ATF1500ABV-15AI

Overview

The ATF1500ABV-15AI is a high-performance, high-density complex programmable logic device (CPLD) manufactured by Microchip Technology. Built on advanced EEPROM technology, it features 32 logic macrocells and up to 36 inputs within a 44-pin package. The device supports a supply voltage range of 2.7V to 5.5V with a maximum pin-to-pin delay of 15 ns and registered operation speeds up to 52.6 MHz. It includes flexible macrocell architecture, global/regional buses, and power management features such as a pin-controlled standby mode reducing current to typically 5 µA.

Feature Summary

• EEPROM-based non-volatile technology with 10,000 program/erase cycles and 20-year data retention
• 32 macrocells with fully connected global input and feedback architecture
• Pin-controlled low-power standby mode (typically 5 µA) and automatic speed/power management
• Programmable output slew rate control to reduce system noise

Applications

• Replacing TTL, SSI, MSI, and classic PLDs in digital logic designs
• State machine initialization and control logic
• Complex combinational and sequential logic functions requiring reprogrammability

Procurement Notes

Verify the specific package type required for the -15AI suffix, which corresponds to Industrial temperature range (-40°C to 85°C). Confirm whether the 'A' or 'J' package variant (TQFP or PLCC) is needed, as the ordering code distinguishes between 44A (TQFP) and 44J (PLCC). Ensure design tools support the ATF1500ABV family for compilation and programming.

Selection Notes

Select this component when a dense CPLD with EEPROM reprogrammability is required for industrial environments. The 15 ns speed grade offers a balance between performance and power consumption. Consider the available I/O count (32 I/O + 4 dedicated inputs) and the need for global control signals like clock, reset, and output enable before finalizing the choice.

Part Context

This part belongs to the ATF1500ABV series, which utilizes Atmel's (now Microchip) advanced EEPROM technology. It is distinct from the Flash-based ATF1500A series. The -15AI designation specifically indicates the 15 ns speed grade and Industrial operating temperature range, differentiating it from Commercial variants.

Replacement Considerations

Direct pin-compatible replacements within the same family include ATF1500ABV-12AC/JC/AI/JI for faster speeds or ATF1500ABV-15AC/JC for commercial temperatures. For industrial applications requiring similar density, verify compatibility with other ATF15xx series devices, noting potential differences in macrocell configuration or I/O counts.
