ATF22LV10C-15SI

Overview

The ATF22LV10C-15SI is a high-performance, low-voltage Electrically Erasable Programmable Logic Device (EEPLD) manufactured by Microchip Technology. It features an advanced CMOS Flash memory architecture with 12 dedicated inputs and 10 I/O macrocells. The device operates within a supply voltage range of 3.0V to 5.5V and supports industrial temperature ranges from -40°C to +85°C. Key electrical parameters include a maximum propagation delay of 15ns, a typical standby current of 10µA in power-down mode, and a maximum operating frequency of 62.5MHz without feedback. It includes user-controlled power-down capabilities and pin-keeper circuits to maintain logic states.

Feature Summary

• Low-voltage operation with a 3.0V to 5.5V supply range
• User-controllable power-down pin for reduced standby power (10µA typical)
• 10 Macrocells with variable product term architecture (8-16 terms per output)
• CMOS and TTL compatible inputs and outputs with 5V tolerant I/Os

Applications

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

Procurement Notes

Verify the package type 'SI' corresponds to the 24-lead Plastic Gull Wing Small Outline (SOIC) configuration as defined in the ordering information table. Confirm that the design file utilizes the Power-down (PD) feature if the PD pin functionality is required, as this alters the JEDEC fuse map. Ensure compliance with RoHS standards if lead-free packaging is specified.

Selection Notes

Select the ATF22LV10C-15SI when a low-voltage EEPLD solution with specific power management requirements is needed. The -15 speed grade provides a 15ns maximum propagation delay, suitable for applications requiring up to 62.5MHz clock frequencies. Consider the SOIC package for surface-mount assembly needs. Verify compiler mode settings to enable the power-down feature if system power reduction is critical.

Part Context

This component belongs to the Atmel ATF22LV10C family of high-performance EEPLDs. It is designed to emulate standard 24-pin PAL devices while offering reprogrammability via Flash technology. The device supports various compiler modes including PAL, GAL, and Power-down modes, allowing flexibility in logic design implementation. It shares architectural similarities with the ATF22V10C but operates at lower voltages.

Replacement Considerations

Direct replacements include other ATF22LV10C variants with different speed grades or packages, such as ATF22LV10C-10SI for faster performance or ATF22LV10C-15SC for PLCC packaging. Cross-family replacements like the ATF22V10C series may require voltage level adjustments.
