ATF750C-15JC

Complex Programmable Logic Devices Overview

The ATF750C-15JC is a high-speed, electrically-erasable complex programmable logic device (CPLD) manufactured by Microchip Technology. It operates at a maximum supply voltage of 5V and features a propagation delay of 15 ns. The device provides 10 macrocells, 10 I/O pins, and 12 inputs within a 28-pin Plastic J-leaded Chip Carrier (PLCC) package. It supports D- or T-type flip-flops with individual clocking capabilities and includes programmable pin-keeper circuits to prevent floating inputs.

Complex Programmable Logic Devices Feature Summary

• High-density CPLD architecture with 171 total product terms, 20 sum terms, and 20 flip-flops in a 24/28-pin form factor.
• Advanced electrically-erasable technology allowing 1000 erase/write cycles and 20-year data retention.
• Programmable pin-keeper circuits eliminate the need for external pull-up resistors on unused inputs.
• Individual asynchronous reset and selectable D/T-type flip-flop configurations for each register.

Complex Programmable Logic Devices Applications

• Complex state machine implementation
• Bus interface logic replacement
• Address decoding and control logic

Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'JC' against official ordering tables. The datasheet lists 'J' as the code for PLCC packages but does not explicitly define 'JC'. Confirm if this denotes a commercial temperature grade variant or a specific packaging option. Ensure compliance with RoHS requirements if lead-free operation is necessary, as standard versions may contain lead.

Complex Programmable Logic Devices Selection Notes

Select the ATF750C-15JC when a 15 ns speed grade is required for 5V applications. Compare against the ATF750CL-15 series if low-power standby current (1 mA) is critical, as the standard C series draws significantly more current. Ensure the design utilizes the 28-pin PLCC footprint and accounts for the 5V ±5% or ±10% supply tolerance.

Complex Programmable Logic Devices Part Context

This component belongs to the ATF750C family, which serves as a superset of the 22V10 architecture. It offers enhanced logic flexibility compared to legacy devices like the ATV750B/L. The device is designed to replace older PAL/GAL logic with higher density and reprogrammability while maintaining backward compatibility in pinout and basic functionality.

Complex Programmable Logic Devices Replacement Considerations

Direct functional replacements include the ATF750CL-15JU for low-power variants. For migration from legacy parts, the ATF750C can replace ATV750(L) and ATV750B(L) devices using compatible JEDEC files. Verify that third-party programmers support the V750 cross-programming mode if migrating existing designs.
