ATF22LV10C-15JI

Overview

The ATF22LV10C-15JI is a high-performance Electrically Erasable Programmable Logic Device (EEPLD) manufactured by Microchip Technology. It features 12 dedicated inputs and 10 I/O macrocells within a 24-lead Plastic Dual In-line Package (PDIP). The device operates on a 3.0V to 5.5V supply voltage with a maximum propagation delay of 15ns. It utilizes advanced Flash memory technology, offering reprogrammability, 20-year data retention, and 100 erase/write cycles. Key electrical characteristics include a typical standby power consumption of 10µA in power-down mode and industrial temperature range operation from -40°C to +85°C.

Feature Summary

• Advanced Low-voltage EEPLD Architecture: Supports 3.0V to 5.5V operation with CMOS and TTL compatible I/Os.
• User-controlled Power-down Mode: Reduces supply current to typically 10µA when the PD pin is active.
• High Reliability Flash Memory: Provides 20-year data retention, 100 erase/write cycles, and 200mA latchup immunity.
• Pin-keeper Circuits: Maintains input and I/O pins at previous logic states when idle to eliminate static power.

Applications

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

Procurement Notes

Verify package type compatibility as the 'J' suffix denotes a 28-lead PLCC package in standard ordering codes, while 'I' indicates Industrial temperature range. Confirm RoHS compliance status if lead-free components are required, noting that lead-based packages are becoming obsolete. Ensure design files account for the specific compiler mode if utilizing the power-down feature.

Selection Notes

Select the ATF22LV10C-15JI for applications requiring low-power standby modes and industrial temperature stability (-40°C to +85°C). The 15ns speed grade offers a balance between performance and power dissipation. Ensure the design utilizes the PD pin configuration if zero-power standby is critical, as this disables one logic array input. Verify that the 24-pin DIP footprint matches the PCB layout requirements.

Part Context

This component belongs to the Atmel ATF22LV10C family of high-performance EEPLDs. It is part of the broader ATF22V10 series, distinguished by its low-voltage operation (3.0V minimum) compared to standard 5V-only devices. The device serves as a drop-in replacement for many legacy PAL devices due to its universal architecture and standard pinouts.

Replacement Considerations

Direct substitutes include other ATF22LV10C variants with different speed grades or packages, such as ATF22LV10C-10JI for faster switching. For non-low-voltage applications, the ATF22V10B series may be considered, though voltage tolerances differ. Always verify pinout compatibility and programming tool support before substitution.
