ATF1500ABV-15JI

Overview

The ATF1500ABV-15JI is a high-performance, high-density electrically-erasable complex programmable logic device (CPLD) manufactured by Microchip Technology. It features 32 macrocells and up to 36 inputs in 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. Registered operation reaches up to 52.6 MHz. It includes advanced power management with a typical standby current of 5 µA and a pin-controlled power-down mode reducing current to less than 10 µA. The component is available in Industrial temperature ranges (-40°C to 85°C) and offers 10,000 program/erase cycles.

Feature Summary

• High-density architecture with 32 logic macrocells and fully connected global/regional buses.
• Flexible macrocell design supporting D/T/Latch configurable flip-flops and individual register control signals.
• Advanced power management including pin-controlled 5 µA standby mode and programmable pin-keeper inputs.
• Robust reliability with 200 mA latchup immunity, 2000V ESD protection, and 20-year data retention.

Applications

• Integration of TTL, SSI, MSI, and classic PLD logic functions.
• Complex combinatorial and sequential logic designs requiring high performance.
• Applications necessitating low-power standby modes and pin-keeper functionality for unused lines.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's datasheet to confirm package type and temperature range. The 'J' suffix indicates a 44-lead Plastic J-leaded Chip Carrier (PLCC) package, while 'I' denotes the Industrial temperature range (-40°C to 85°C). Ensure design compatibility with the specified 15 ns speed grade and 2.7V–5.5V operating voltage before procurement.

Selection Notes

Select this component when a high-density CPLD with flexible macrocell resources and low-power features is required. The ATF1500ABV-15JI is suitable for designs needing industrial temperature stability and robust noise immunity via pin-keepers. Compare against other speed grades if higher frequencies are needed, noting that commercial variants may require derating for industrial use.

Part Context

This part belongs to the ATF1500ABV series of Electrically Erasable Programmable Logic Devices (EEPLDs). It utilizes advanced EEPROM technology for non-volatile configuration. The series is characterized by its fully connected input and feedback logic array, which simplifies logic placement and eliminates pinout changes due to design modifications.

Replacement Considerations

To utilize commercial product for Industrial temperature ranges, downgrade one speed grade from the “I” to the “C” device (e.g., 7 ns “C” = 10 ns “I”) and de-rate power by 30%.
