ATF22LV10C-10JC

Overview

The ATF22LV10C-10JC is a high-performance, low-voltage Electrically Erasable Programmable Logic Device (EEPLD) manufactured by Microchip Technology. It features 10 macrocells and supports up to 10 I/Os with a maximum propagation delay of 10 ns. The device operates within a supply voltage range of 3.0V to 5.5V and includes an optional user-controlled power-down pin for reduced standby current. It utilizes advanced electrically erasable Flash memory technology, offering reprogrammability, 20-year data retention, and 100 erase/write cycles.

Feature Summary

• Advanced Low-voltage EEPLD with 3.0V to 5.5V operating range
• User-controlled Power-down Pin Option for zero standby power
• CMOS and TTL Compatible Inputs and Outputs
• High-reliability CMOS Process with 200mA Latchup Immunity

Applications

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

Procurement Notes

Verify the package type associated with the 'JC' suffix, which corresponds to the 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 mode configuration if utilized in the design.

Selection Notes

Select the ATF22LV10C-10JC when a PLCC package is required for commercial temperature ranges (0°C to 70°C). For industrial temperature applications (-40°C to +85°C), consider the ATF22LV10C-10JI variant instead. Ensure the design accounts for the 10ns max propagation delay and verify that the 3.0V to 5.5V supply range meets system requirements.

Part Context

This component belongs to the Atmel ATF22LV10C family of high-performance CMOS programmable logic devices. It is designed to emulate standard 24-pin PAL devices while providing enhanced flexibility through electrically erasable Flash memory. The device architecture allows for complex logic functions using variable product terms and includes features like register preload and security fuses.

Replacement Considerations

Public confirmed substitute part numbers: ATF22LV10C-10JI (Industrial Temp, PLCC), ATF22LV10C-10PC (Commercial Temp, PDIP), ATF22LV10C-10SC (Commercial Temp, SOIC), ATF22LV10C-10XC (Commercial Temp, TSSOP).

FAQ

What is the function of the PD pin?

The PD pin acts as a programmable power-down pin. When active, it reduces the device supply current to less than 100µA, placing the device in a zero standby power-down mode where all output data and internal logic states are latched.

How many product terms are available per macrocell?

Each output macrocell is allocated from 8 to 16 product terms, allowing for highly complex logic functions. Two additional product terms are included for synchronous and asynchronous reset.

What is the typical standby power consumption in power-down mode?

In power-down mode, the typical standby power consumption is 10µA at VCC = 3.6V with inputs at 0 and outputs open.
