ATF750C-15PC

Complex Programmable Logic Devices Overview

The ATF750C-15PC is a high-speed, electrically-erasable CPLD from the ATF750C series. It features 20 macrocells with 171 total product terms and supports D- or T-type flip-flops. The device operates at 5V ± 5% (Commercial) or 5V ± 10% (Industrial/Military). Key electrical parameters include a maximum pin-to-pin propagation delay of 15 ns, a maximum operating frequency of 71 MHz (no feedback), and standby supply currents up to 180 mA for Commercial grades. It offers 10 I/O pins, 12 inputs, and programmable pin-keeper circuits.

Complex Programmable Logic Devices Feature Summary

• High-density logic architecture providing 20 sum terms and 20 individually configurable flip-flops.
• Flexible clocking options allowing individual product term clocks or direct input pin clocking for each register.
• Programmable pin-keeper circuits on all I/O pins to prevent floating states and reduce power consumption.
• Backward compatible with ATV750B/BL and ATV750/L devices while offering enhanced logic flexibility.

Complex Programmable Logic Devices Applications

• Replacement for standard 22V10 PALs requiring higher density.
• Complex state machine implementations utilizing buried registers.
• Address decoding and bus interface logic in embedded systems.
• Migration from legacy Atmel ATV750(L) architectures.

Complex Programmable Logic Devices Procurement Notes

Verify the package suffix 'PC' corresponds to the specific plastic dual inline package variant required. Confirm the temperature grade matches the application environment, as the base model number does not explicitly define the commercial or industrial range without additional suffixes. Ensure programming tools support the V750 mnemonic for JEDEC compatibility.

Complex Programmable Logic Devices Selection Notes

Select this component when upgrading from 22V10 devices to gain access to registered outputs and flexible clocking. Compare the 15 ns speed grade against -7 and -10 variants if higher performance is needed. Consider the ATF750CL variant if low-power standby operation (1 mA) is critical, noting that the standard C version draws significantly more current in standby mode.

Complex Programmable Logic Devices Part Context

The ATF750C is part of Atmel's (now Microchip) advanced CPLD family, designed as a superset of the popular 22V10 architecture. It utilizes electrically-erasable CMOS technology, allowing for 1000 erase/write cycles and 20-year data retention. The device integrates both combinatorial and registered logic within a compact 24-pin footprint.

Complex Programmable Logic Devices Replacement Considerations

Direct functional replacement for ATV750, ATV750L, ATV750B, and ATV750BL devices. When migrating from these legacy parts, ensure the design compiler settings account for the additional macrocells and pin-keeper features available in the ATF750C.
