ATF22V10CZ-15JC

Overview

The ATF22V10CZ-15JC is a high-performance CMOS electrically erasable programmable logic device (PLD) utilizing Flash memory technology. It features 12 dedicated inputs and 10 I/O macrocells, each with 8 to 16 product terms. The device offers a maximum pin-to-pin propagation delay of 15 ns and operates at frequencies up to 83.3 MHz. It supports zero standby power via Input Transition Detection (ITD), consuming 100 µA maximum in standby mode. The component is housed in a 28-lead Plastic J-leaded Chip Carrier (PLCC) package and is rated for commercial operation between 0°C and +70°C.

Feature Summary

• Zero Standby Power: Utilizes patented Input Transition Detection (ITD) circuitry to automatically power down when idle, achieving 100 µA maximum standby current.
• High Performance: Delivers a maximum 15 ns pin-to-pin delay and supports external feedback clocking up to 83.3 MHz.
• Flash Memory Architecture: Electrically erasable and reprogrammable with 100 erase/write cycles, 20-year data retention, and 200mA latchup immunity.
• Universal Compatibility: Emulates industry-standard 24-pin PAL devices and includes internal pin-keeper circuits to maintain logic states.

Applications

• State machine implementation requiring automatic initialization via power-up reset.
• Logic replacement for legacy 22V10 family and combinatorial PLDs.
• Systems requiring low-power management through automatic idle power-down modes.

Procurement Notes

Verify the ordering suffix 'JC' corresponds to the 28-lead PLCC package and commercial temperature range (0°C to +70°C). Confirm that the specific speed grade matches the required 15 ns maximum propagation delay. Check for RoHS compliance status as standard packages may be obsolete or transitioning to green options.

Selection Notes

Select this part for designs needing direct replacement of 22V10 architectures with enhanced reprogrammability. Ensure the application fits within the commercial temperature range; use industrial variants for -40°C to +85°C environments. Consider the ATF22V10CQZ series for new designs, as the CZ series is noted as not recommended for new design.

Part Context

This component belongs to the ATF22V10C(Q)Z family of high-performance EEPLDs. The datasheet explicitly states that the ATF22V10CZ series is obsolete and replaced by the ATF22V10CQZ. The 'C' designation indicates commercial temperature grading, while 'J' denotes the PLCC package type.

Replacement Considerations

The ATF22V10CZ series is officially replaced by the ATF22V10CQZ. For equivalent performance in industrial temperatures, consider ATF22V10CQZ-20JI or similar CQZ variants. Direct functional replacement is supported for most 24-pin PAL devices.

FAQ

How does the device achieve zero standby power?

The device uses Atmel's patented Input Transition Detection (ITD) circuitry. When inputs are idle, the ITD detects no transitions and automatically powers down the internal logic, reducing supply current to 100 µA maximum.

What is the function of the pin-keeper circuits?

Internal pin-keeper circuits on input and I/O pins eliminate static power consumption from pull-up resistors and hold the pins at their previous logic state when not actively driven externally.

Can this device replace standard PAL devices?

Yes, the ATF22V10CZ incorporates a superset of generic architectures allowing it to directly replace the 22V10 family and most 24-pin combinatorial PLDs.
