ATF22LV10C-15JC

Overview

The ATF22LV10C-15JC is a high-performance, low-voltage Electrically Erasable Programmable Logic Device (EEPLD) manufactured by Microchip Technology. It features 12 inputs and 10 I/O macrocells with a variable product term architecture providing 8 to 16 terms per output. The device operates within a 3.0V to 5.5V supply range and offers a maximum propagation delay of 15 ns. It includes a user-controlled power-down pin option for reduced standby current and supports industrial temperature ranges.

Feature Summary

• Low-voltage operation from 3.0V to 5.5V with typical standby power of 10µA in power-down mode
• 10ns maximum propagation delay and up to 83.3 MHz operating frequency
• CMOS and TTL compatible inputs and outputs with 5V tolerant pins
• Advanced electrically erasable Flash memory technology with 100 erase/write cycles

Applications

• Glue logic for 3.3V systems
• DMA Control
• State Machine Control
• Graphics processing

Procurement Notes

Verify the package type corresponding to the 'JC' suffix, which indicates a 28-lead Plastic J-leaded Chip Carrier (PLCC). Confirm RoHS compliance status as lead-based packages are becoming obsolete. Ensure programming equipment supports the specific JEDEC file format required for the power-down feature if utilized.

Selection Notes

Select this component when low voltage operation down to 3.0V is required alongside standard PLD functionality. The -15 speed grade provides a 15 ns max propagation delay suitable for moderate-speed applications. Consider the power-down feature if system power management is critical, noting that the PD pin cannot be used as a regular logic input if this feature is enabled.

Part Context

This part belongs to the ATF22LV10C family of advanced low-voltage EEPLDs. It is designed to replace older PAL/GAL devices while offering reprogrammability and lower power consumption. The device utilizes Atmel's proven electrically erasable Flash memory technology, ensuring high reliability and data retention.

Replacement Considerations

Direct replacements include other ATF22LV10C variants with different speed grades or packages, such as ATF22LV10C-10JC. Cross-family replacements like the ATF22V10C may require voltage level adjustments as they typically operate at 5V only.
