Description
The HFA5253 is a very high speed monolithic pin driver solution for high performance test systems. The device will switch at high data rates between two input voltage levels providing variable amplitude pulses. Slew Rate Control pins provide independent control over positive and negative slew rate allowing the customer to optimize the pin driver speed for their application. The output impedance is trimmed to achieve a precision 50Ω source for impedance matching.
Two differential ECL/TTL compatible inputs control the operation of the HFA5253, one controlling the VHIGH/VLOW switching and the other controlling the output’s highimpedance state. The HFA5253’s 800MHz data rate makes it compatible with today’s high-speed VLSI test systems and the +8V to -3V output swing satisfies the most stringent testing requirements of all common logic families.
The HFA5253 is manufactured in Harris’ proprietary complementary bipolar UHF-1 process.

DESCRIPTION
The DS87C520/DS83C520 EPROM/ROM High-Speed Micro is a fast 8051-compatible microcontroller. It features a redesigned processor core without wasted clock and memory cycles. As a result, it executes every 8051 instruction between 1.5 and 3 times faster than the original for the same crystal speed. Typical applications will see a speed improvement of 2.5 times using the same code and the same crystal. The DS87C520/DS83C520 offers a maximum crystal speed of 33 MHz, resulting in apparent execution speeds of 82.5 MHz (approximately 2.5X).
The DS87C520/DS83C520 is pin-compatible with all three packages of the standard 8051 and includes standard resources such as three timer/counters, serial port, and four 8-bit I/O ports. It features 16 kB of EPROM or Mask ROM with an extra 1 kB of data RAM. Both OTP and windowed packages are available.
Besides greater speed, the microcontroller includes a second full hardware serial port, seven additional interrupts, programmable Watchdog Timer, Brown-out Monitor, and Power-Fail Reset. The device also provides dual data pointers (DPTRs) to speed block data memory moves. It also can adjust the speed of MOVX data memory access from two to nine machine cycles for flexibility in selecting external memory and peripherals.
A new Power Management Mode (PMM) is useful for portable applications. This feature allows software to select a lower speed clock as the main time base. While normal operation has a machine cycle rate of 4 clocks per cycle, the PMM runs the processor at 64 or 1024 clocks per cycle. For example, at 12 MHz, standard operation has a machine cycle rate of 3 MHz. In Power Management Mode, software can select either 187.5 kHz or 11.7 kHz machine cycle rate. There is a corresponding reduction in power consumption when the processor runs slower.
The EMI reduction feature allows software to select a reduced emission mode. This disables the ALE signal when it is unneeded.
The DS83C520 is a factory Mask ROM version of the DS87C520 designed for high-volume, costsensitive applications. It is identical in all respects to the DS87C520, except that the 16 kB of EPROM is replaced by a user-supplied application program. All references to features of the DS87C520 will apply to the DS83C520, with the exception of EPROM-specific features where noted. Please contact your local Dallas Semiconductor sales representative for ordering information.

General Description
The AMIS-42670 CAN transceiver is the interface between a controller area network (CAN) protocol controller and the physical bus and may be used in both 12V and 24V systems. The transceiver provides differential transmit capability to the bus and differential receive capability to the CAN controller. Due to the wide common-mode voltage range of the receiver inputs, the AMIS-42670 is able to reach outstanding levels of electromagnetic susceptibility (EMS). Similarly, extremely low electromagnetic emission (EME) is achieved by the excellent matching of the output signals.
The AMIS-42670 is the industrial version of the AMIS-30660 and primarily intended for applications where long network lengths are mandatory. Examples are elevators, in-building networks, process control and trains. To cope with the long bus delay the communication speed needs to be low. AMIS-42670 allows low transmit data rates down 10 Kbit/s or lower.

Key Features
*Fully compatible with the ISO 11898-2 standard
*Certified “Authentication on CAN Transceiver Conformance (d1.1)”
*Wide range of bus communication speed (0 up to 1 Mbit/s)
*Allows low transmit data rate in networks exceeding 1 km
*Ideally suited for 12V and 24V industrial and automotive applications
*Low electromagnetic emission (EME) common-mode choke is no longer required
*Differential receiver with wide common-mode range (+/- 35V) for high EMS
*No disturbance of the bus lines with an un-powered node
*Thermal protection
*Bus pins protected against transients
*Silent mode in which the transmitter is disabled
*Short circuit proof to supply voltage and ground
*Logic level inputs compatible with 3.3V devices
