EPM7128AETC144-10N

Complex Programmable Logic Devices Overview

The EPM7128AETC144-10N is a Complex Programmable Logic Device (CPLD) belonging to the Altera MAX 7000A family. It utilizes second-generation Multiple Array MatriX (MAX) architecture and CMOS EEPROM technology, operating at a supply voltage of 3.3V. The device integrates 128 macrocells, providing approximately 2,500 usable logic gates distributed across eight Logic Array Blocks (LABs). It features a TQFP-144 package with up to 100 user I/O pins. Key electrical parameters include a maximum pin-to-pin propagation delay of 5 ns and a counter frequency reaching 175.4 MHz. The component supports In-System Programming (ISP) via an IEEE Std. 1149.1 JTAG interface.

Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'N' against official manufacturer documentation to confirm compliance status or environmental specifications, as suffix definitions can vary by revision. Confirm availability status, as older CPLD families may be discontinued or subject to last-time buys. Ensure design compatibility with 3.3V power domains and JTAG programming infrastructure.

Complex Programmable Logic Devices Selection Notes

Select this component for designs requiring deterministic timing and non-volatile configuration without external memory. The 5 ns delay and high clock speeds suit moderate-speed digital logic applications. Compare against MAX 7000S variants if 5V operation is required, noting that while pin-compatible, voltage levels differ. Ensure the TQFP-144 footprint matches PCB layout constraints.

Complex Programmable Logic Devices Part Context

This part belongs to the MAX 7000A series, an evolution of the MAX 7000 family designed for lower voltage operation. It serves as a drop-in replacement for many 5V MAX 7000S designs due to pin compatibility. The EEPROM technology allows for unlimited reprogramming cycles, distinguishing it from fuse-based PLDs. It represents a mature, high-reliability solution for legacy and industrial embedded systems.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-compatible replacements within the same voltage domain include other members of the MAX 7000A family, such as the EPM7128AETC144-7N or EPM7256AETC144-10N, depending on logic density requirements. For 5V applications, MAX 7000S devices like the EPM7128STC144-10N offer functional equivalence but require voltage level adjustment.
