DESCRIPTION
The DS1315 Phantom Time Chip is a combination of a CMOS timekeeper and a nonvolatile memory controller. In the absence of power, an external battery maintain the timekeeping operation and provides power for a CMOS static RAM. The watch keeps track of hundredths of seconds, seconds, minutes, hours, day, date, month, and year information. The last day of the month is automatically adjusted for months with less than 31 days, including leap year correction. The watch operates in one of two formats: a 12-hour mode with an AM/PM indicator or a 24-hour mode. The nonvolatile controller supplies all the necessary support circuitry to convert a CMOS RAM to a nonvolatile memory. The DS1315 can be interfaced with either RAM or ROM without leaving gaps in memory.

FEATURES
*Real-Time Clock Keeps Track of Hundredths of Seconds, Seconds, Minutes, Hours, Days, Date of the Month, Months, and Years
*Adjusts for Months with Fewer than 31 Days
*Automatic Leap Year Correction Valid Up to 2100
*No Address Space Required to Communicate with RTC

Functional Description
The Cypress STK15C88 is a 256Kb fast static RAM with a nonvolatile element in each memory cell. The embedded nonvolatile elements incorporate QuantumTrap™ technology producing the world’s most reliable nonvolatile memory. The SRAM provides unlimited read and write cycles, while independent, nonvolatile data resides in the highly reliable QuantumTrap cell. Data transfers from the SRAM to the nonvolatile elements (the STORE operation) takes place automatically at power down. On power up, data is restored to the SRAM (the RECALL operation) from the nonvolatile memory. Both the STORE and RECALL operations are also available under software control.
PowerStore nvSRAM products depend on the intrinsic system capacitance to maintain system power long enough for an automatic store on power loss. If the power ramp from 5 volts to 3.6 volts is faster than 10 ms, consider our 14C88 or 16C88 for more reliable operation.

Features
*25 ns and 45 ns access times
*Pin compatible with industry standard SRAMs
*Automatic nonvolatile STORE on power loss
*Nonvolatile STORE under Software control
*Automatic RECALL to SRAM on power up
*Unlimited Read/Write endurance
*Unlimited RECALL cycles
*1,000,000 STORE cycles
*100 year data retention
*Single 5V+10% power supply
*Commercial and Industrial Temperatures
*28-pin (300 mil and 330 mil) SOIC packages
*RoHS compliance

DESCRIPTION
The PA84 is a high voltage operational amplifier designed for output voltage swings up to ±145V with a dual supply or 290V with a single supply. Two versions are available. The new PA84S, fast settling amplifier can absorb differential input overvoltages up to ±50V while the established PA84 and PA84A can handle differential input overvoltages of up to ±300V. Both versions are protected against common mode transients and overvoltages up to the supply rails. High accuracy is achieved with a cascode input circuit configuration. All internal biasing is referenced to a zener diode fed by a FET constant current source. As a result, the PA84 features an unprecedented supply range and excellent supply rejection. The output stage is biased-on for linear operation. External phase compensation allows for user flexibility in obtaining the maximum slew rate. Fixed current limits protect these amplifiers against shorts to common at supply voltages up to 150V. For operation into inductive loads, two external flyback pulse protection diodes are recommended. However, a heatsink may be necessary to maintain the proper case temperature under normal operating conditions.
This hybrid integrated circuit utilizes a beryllia (BeO) substrate, thick film resistors, ceramic capacitors and semiconductor chips to maximize reliability, minimize size and give top performance. Ultrasonically bonded aluminum wires provide reliable interconnections at all operating temperatures. The 8-pin TO-3 package is hermetically sealed and electrically isolated. The use of compressible thermal isolation washers and/or improper mounting torque will void the product warranty. Please see “General Operating Considerations”.

FEATURES
*HIGH SLEW RATE — 200V/μs
*FAST SETTLING TIME — .1% in 1μs (PA84S)
*FULLY PROTECTED INPUT — Up to ±150v
*LOW BIAS CURRENT, LOW NOISE — FET Input
*WIDE SUPPLY RANGE — ±15V to ±150V

APPLICATIONS
*HIGH VOLTAGE INSTRUMENTATION
*ELECTROSTATIC TRANSDUCERS & DEFLECTION
*PROGRAMMABLE POWER SUPPLIES UP TO 290V
*ANALOG SIMULATORS
