When it comes to small-scale, deterministic logic design, Programmable Logic Devices (PLDs) like the ATF750C-15JI provide a cost-effective and power-efficient alternative to FPGAs and CPLDs. With reliable EEPROM-based configuration and fast propagation delay, the ATF750C-15JI is widely used in automotive control, industrial automation, and embedded telecom systems.
In this post, we explore the technical capabilities, application scenarios, and procurement benefits of the ATF750C-15JI — a legacy-friendly solution still trusted by engineers and system integrators worldwide.
What is the ATF750C-15JI?
The ATF750C-15JI is a high-performance PLD (Programmable Logic Device) based on Electrically Erasable Programmable Read-Only Memory (EEPROM) technology. Designed by Microchip Technology (formerly Atmel), this device belongs to the ATF750 series, known for its reliable architecture and pin-compatibility with older PAL devices.
It is a drop-in replacement for the PAL22V10 and ATF22V10C, with additional capabilities including output macrocell flexibility, asynchronous clocking, and configurable feedback paths.

Advantages of the ATF750C-15JI
✅ Drop-In Compatibility
The ATF750C is fully pin-compatible with PAL22V10 and earlier Atmel devices, making it ideal for legacy system upgrades or maintenance of long-life industrial and military systems.
✅ Low Power & Fast Switching
With a 15 ns propagation delay and EEPROM configuration, it offers excellent performance for control logic that must respond quickly and consistently.
✅ Flexible Logic Design
Each output macrocell is individually configurable as registered or combinational. This allows the same device to serve multiple roles within a system: counters, decoders, state machines, and more.
✅ Reprogrammable EEPROM Logic
Unlike one-time programmable PALs, the ATF750C can be reprogrammed in development or in-system, which is ideal for iterative design and prototyping.
