ATF750C-10JI

Complex Programmable Logic Devices Overview

The ATF750C-10JI is a high-speed, electrically-erasable complex programmable logic device (CPLD) manufactured by Microchip Technology. It features 24 pins in a Plastic J-leaded Chip Carrier (PLCC) package and operates at a maximum propagation delay of 10 ns with a 5V supply. The device provides 171 total product terms, 20 sum terms, and 20 individually configurable D- or T-type flip-flops. It supports full military temperature ranges from -55°C to +125°C and includes programmable pin-keeper circuits to prevent floating inputs.

Complex Programmable Logic Devices Feature Summary

• High-density CPLD architecture with 171 product terms and 20 registered outputs
• Maximum 10 ns pin-to-pin propagation delay under 5V operation
• Individually configurable D- or T-type flip-flops with asynchronous reset and synchronous preset
• Programmable pin-keeper circuits eliminate the need for external pull-up resistors

Complex Programmable Logic Devices Applications

• Complex state machine implementation
• Bus interface logic design
• Replacement for legacy 22V10 PLDs
• Military-grade digital control systems

Complex Programmable Logic Devices Procurement Notes

Verify that the ordering suffix 'JI' corresponds to the 28-lead PLCC package and Industrial/Military temperature range as specified in the datasheet tables. Confirm RoHS compliance status if required, noting that specific green package options may have distinct suffixes. Ensure the design tool supports the V750 device mnemonic for proper fuse pattern programming.

Complex Programmable Logic Devices Selection Notes

Select this component when a 24-pin CPLD with higher logic density than standard PALs is required. The 10 ns speed grade offers a balance between performance and power consumption compared to the 7.5 ns variant. Ensure the application requires the full -55°C to +125°C operating range, as commercial variants are limited to 0°C to 70°C.

Complex Programmable Logic Devices Part Context

The ATF750C series serves as a superset of the 22V10 architecture, offering enhanced flexibility through additional product terms and flip-flops. It is backward compatible with ATV750B/BL and ATV750/L devices, allowing for direct replacement or speed upgrades in existing designs without significant schematic changes.

Complex Programmable Logic Devices Replacement Considerations

The ATF750C is a direct functional replacement for the ATV750(L) and ATV750B(L). When migrating from these legacy devices, ensure the third-party programmer supports the V750 cross-programming mode to automatically handle user row bits and disable pin-keeper features if necessary.
