ATF1500ABV-12JC

Overview

The ATF1500ABV-12JC is a high-performance, high-density electrically erasable complex programmable logic device (CPLD) manufactured by Microchip Technology. It features 32 logic macrocells and supports up to 36 inputs with a maximum pin-to-pin delay of 12 ns. The device operates on a supply voltage between 2.7V and 5.5V and utilizes advanced EEPROM technology for complete reprogrammability. It is housed in a 44-lead Plastic J-leaded Chip Carrier (PLCC) package and is rated for commercial operation within an ambient temperature range of 0°C to 70°C.

Feature Summary

• High-density architecture with 32 macrocells, fully connected input and feedback logic array, and 12 ns maximum pin-to-pin delay.
• Flexible macrocell design supporting D/T/Latch configurable flip-flops, global/individual register control signals, and programmable output slew rates.
• Advanced power management including automatic standby mode and pin-controlled low-power shutdown (typically 5 µA).
• EEPROM-based non-volatile programming offering 10,000 program/erase cycles, 20-year data retention, and integrated security fuse.

Applications

• Integration of TTL, SSI, MSI, and classic PLD logic functions into single-chip solutions.
• State machine initialization and sequential logic operations requiring registered outputs up to 90.9 MHz.
• Bus-friendly designs utilizing programmable pin-keeper circuits to prevent floating inputs and reduce system noise.

Procurement Notes

Verify the specific ordering suffix 'JC' corresponds to the 44J PLCC package and commercial temperature range (0°C to 70°C) as defined in the official datasheet. Confirm that the required speed grade (-12) meets the system timing constraints, specifically the 12 ns max propagation delay and 62.5 MHz external feedback frequency. Ensure design tools support the ATF1500 series for JEDEC file generation and programming.

Selection Notes

Select this component when a high-density CPLD with 32 macrocells and fast 12 ns switching speeds is required for commercial environments. The PLCC package is suitable for through-hole mounting or specific socketed applications. Consider the -15AC variant if lower performance requirements allow for cost optimization, or the Industrial variants if extended temperature ranges are necessary. Verify power supply stability within the 2.7V to 5.5V operating window.

Part Context

This part belongs to the ATF1500ABV family of Electrically Erasable PLDs from Microchip (formerly Atmel). The family offers backward compatibility with earlier ATF1500 software and hardware ecosystems. The -12JC designation specifies the 12 ns speed grade, Commercial temperature range, and 44-lead PLCC package, distinguishing it from TQFP packages and Industrial temperature options within the same logical family.

Replacement Considerations

Direct functional replacements include other ATF1500ABV speed grades such as ATF1500ABV-15JC for relaxed timing requirements. For package changes, the ATF1500ABV-12AC provides identical electrical characteristics in a 44-lead TQFP package. Cross-family upgrades may require retargeting to higher-density devices like the ATF1504ASV series if additional macrocells are needed.
