ATF1502AS-10JC44

Overview

The ATF1502AS-10JC44 is a high-performance, electrically-erasable Complex Programmable Logic Device (CPLD) from Microchip Technology. It features 32 macrocells with up to 40 product terms per macrocell and operates on a 5V supply. The device provides 44 pins, including 32 bi-directional I/Os and four dedicated inputs. It achieves a maximum pin-to-pin delay of 10 ns and supports registered operation up to 100 MHz. Designed for commercial applications, it functions within a temperature range of 0°C to +70°C.

Feature Summary

• 32 Macrocells with expandable logic structure supporting up to 40 product terms
• In-System Programmability (ISP) via standard 4-pin JTAG interface
• Advanced power management with automatic standby and pin-controlled power-down modes
• PCI-compliant output drivers with programmable slew rate control

Applications

• Logic integration replacing TTL, SSI, MSI, LSI, and classic PLDs
• PCI-based system interface designs requiring high current drive
• State machine initialization and control logic in embedded systems

Procurement Notes

Verify the specific speed grade suffix (-10) against the required timing constraints for your design. Confirm that the commercial temperature range (0°C to +70°C) meets your operational environment requirements. Ensure the PLCC-44 package footprint matches your PCB layout specifications before ordering.

Selection Notes

Select this component when 32 macrocells are sufficient for your logic density needs. The -10 speed grade offers a balance between performance and power consumption at 100 MHz. Consider the ATF1502ASL variant if lower power consumption or industrial temperature ranges are required instead.

Part Context

This part belongs to the ATF1502AS family of high-density CPLDs. It utilizes advanced EEPROM technology allowing for 10,000 program/erase cycles and 20-year data retention. The device is fully reprogrammable and includes security fuse features to protect intellectual property.

Replacement Considerations

The ATF1502ASL series serves as the low-power alternative. For higher density requirements, consider the ATF1504AS or ATF1508AS models within the same family.
