General description
The NE1617A is an accurate two-channel temperature monitor. It measures the temperature of itself and the temperature of a remote sensor. The remote sensor is a diode connected transistor. This can be in the form of either a discrete NPN/PNP, such as the 2N3904/2N3906, or a diode connected PNP built into another die, such as is done on some Intel microprocessors.
The temperature of both the remote and local sensors is stored in a register that can be read via a 2-wire SMBus. The temperatures are updated at a rate that is programmable via the SMBus (the average supply current is dependent upon the update rate—the faster the rate, the higher the current).
In addition to the normal operation, which is to update the temperature at the programmed rate, there is a one-shot mode that will force a temperature update.
There is also an alarm that senses either an overtemperature or undertemperature condition. The trip points for this alarm are also programmable.
The device can have 1 of 9 addresses (determined by 2 address pins), so there can be up to 9 of the NE1617A on the SMBus.
can also be put in standby mode (in order to save power). This can be done either with software (over the SMBus) or with hardware (using the STBY pin).

Features
*Replacement for Maxim MAX1617 and Analog Devices ADM1021
*Monitors local and remote temperature

-±2 °C at 60 °C to 100 °C

*3 V to 5.5 V supply range; 5.5 V tolerant
*70 mA supply current in operating mode
*3 mA (typical) supply current in standby mode
*ESD protection exceeds 2000 V HBM per JESD22-A114, 250 V MM per JESD22-A115, and 1000 V CDM per JESD22-C101

DESCRIPTION
The DS5000FP Soft Microprocessor Chip is an 8051-compatible processor based on NV RAM
technology. It is substantially more flexible than a standard 8051, yet provides full compatibility with the 8051 instruction set, timers, serial port, and parallel I/O ports. By using NV RAM instead of ROM, the user can program and then reprogram the microcontroller while in-system. The application software can even change its own operation, which allows frequent software upgrades, adaptive programs, customized systems, etc. In addition, by using NV SRAM, the DS5000FP is ideal for data-logging applications and it connects easily to a Dallas real-time clock for time stamp and date.
The DS5000FP provides the benefits of NV RAM without using I/O resources. It uses a non-multiplexed Byte-wide address and data bus for memory access. This bus can perform all memory access and provides decoded chip enables for SRAM. This leaves the 32 I/O port pins free for application use. The DS5000FP uses ordinary SRAM and battery backs the memory contents with a user’s external lithium cell. Data is maintained for over 10 years with a very small lithium cell. A DS5000FP also provides crashproof operation in portable systems or systems with unreliable power. These features include the ability to save the operating state, Power-fail Reset, Power-fail Interrupt, and Watchdog Timer.
A user loads programs into the DS5000FP via its on-chip Serial Bootstrap Loader. This function
supervises the loading of code into NV RAM, validates it, then becomes transparent to the user. Software can be stored in an 8-kbyte or 32-kbyte CMOS SRAM. Using its internal Partitioning, the DS5000FP will divide this common RAM into user programmable code and data segments. This Partition can be selected at program loading time, but can be modified anytime later. It will decode memory access to the SRAM, communicate via its Byte-wide bus and write-protect the memory portion designated as ROM.
Combining program and data storage in one device saves board space and cost. The DS5000FP can also access a second 32 kbytes of NV RAM but this area is restricted to data memory. For a user that wants a pre-constructed module using the DS5000FP, RAM, lithium cell, and optional real time clock; the DS2250(T) and DS5000(T) are available and described in separate data sheets. More details are also contained in the User’s Guide section of the Secure Microcontroller Data Book.

FEATURES
*8051-compatible microprocessor adapts to task
- Accesses between 8kB and 64kB of nonvolatile SRAM
- In-system programming via on-chip serial port
- Can modify its own program or data memory
- Accesses memory on a separate Bytewide bus
*Crashproof operation
- Maintains all nonvolatile resources for over 10 years
- Power-fail Reset
- Early Warning Power-fail Interrupt
- Watchdog Timer
- User-supplied lithium battery backs user SRAM for program/data storage

The MAX809 and MAX810 are cost–effective system supervisor circuits designed to monitor VCC in digital systems and provide a reset signal to the host processor when necessary. No external components are required.
The reset output is driven active within 20 msec of VCC falling through the reset voltage threshold. Reset is maintained active for a minimum of 140msec after VCC rises above the reset threshold. The MAX810 has an active–high RESET output while the MAX809 has
an active–low RESET output. The output of the MAX809 is guaranteed valid down to VCC = 1V. Both devices are available in a SOT–23 package.
The MAX809/810 are optimized to reject fast transient glitches on the VCC line. Low supply current of 17mA (VCC = 3.3V) makes these devices suitable for battery powered applications.

GENERAL DESCRIPTION
The Am386®SX/SXL/SXLV microprocessors are lowcost, high-performance CPUs for embedded applications.
Embedded customers benefit from using the Am386 microprocessor in a number of ways.
The Am386SX/SXL/SXLV microprocessors provide embedded customers access to very inexpensive processors and the highest performance of any 386SX available anywhere. The 16-bit data path allows for inexpensive memory design. Full static operation, coupled with 3-V supplies, benefit customers who desire low-power designs. Standby Mode allows the Am386SXL/SXLV microprocessors to be clocked down to 0 MHz (DC) and retain full register contents. A float pin places all outputs in a three-state mode to facilitate board test and debug. Additionally, the Am386SXLV microprocessor comes with System Management Mode (SMM) for system and power management. SMI (System Management Interrupt) is a non-maskable, higher priority interrupt than NMI and has its own code space (1 Mbyte in Real Mode and 16 Mbyte in Protected Mode). SMI can be coupled with the I/O instruction break feature to implement transparent power management of peripherals.
SMM can be used by system designers to implement system and power management code independent of the operating system or the processor mode. Since the Am386SX/SXL/SXLV microprocessors are supported as an embedded product in the E86 family, customers can rely on long-term supply of product, and extended temperature products.
In addition, customers have access to the largest selection of inexpensive development tools, compilers, and chipsets. A large number of PC operating systems and Real Time Operating Systems (RTOS) support the Am386SX/SXL/SXLV microprocessors. This means cheaper development costs, and improved time to market.
The Am386SX/SXL/SXLV microprocessor is available in a small footprint 100-pin Plastic Quad Flat Pack (PQFP) package.

General Description
The LM2688 is a low-cost non-synchronous voltage-mode PWM controller which maintains an accurate and adjustable output voltage for high current, low voltage DC/DC applications such as the Pentium microprocessor family. By using different combinations of feedback resistors, the regulator output voltage can be precisely adjusted to match different requirements. Coming in an 8-lead surface mount package, the LM2688 can be used to control a buck regulator with an load current up to 10A. An on-chip precision trimmed reference allows tight voltage regulation and an internal 150 kHz fixed-frequency oscillator eliminates extra components to set the switching frequency. The LM2688 also provides an ON/ OFF pin which enables the CPU to shutdown the regulator when necessary. Self protection features include a two stage current limit for the output switch and an over temperature shutdown for complete protection under fault conditions. The controller also provides internal loop gain compensation, minimizing the number of external components.

Features
* Adjustable output voltage
* Available in 8-pin surface mount
* Guaranteed 0.5A gate drive current
* Supply voltage up to 40V
* 150 kHz fixed frequency internal oscillator
* TTL shutdown capability
* Low power standby mode, IQ typically <85 μA
* Thermal shutdown and current limit protection

Applications
* Controller for voltage regulators for Pentium, Pentium MMX, K5, K6 MMX, Alpha and PowerPC processors
* Efficient pre-regulator for linear regulators
