EPM7128AETC100-5

Complex Programmable Logic Devices Overview

The Altera EPM7128AETC100-5 is a Complex Programmable Logic Device (CPLD) belonging to the MAX 7000AE family. It utilizes CMOS EEPROM technology and features 128 macrocells, 84 I/O pins, and approximately 2,500 usable gates organized into 8 Logic Array Blocks (LABs). The device operates at a supply voltage of 3.3 V (range 3.0 V to 3.6 V) with a maximum propagation delay of 5 ns and a maximum operating frequency of 192.3 MHz. It supports In-System Programming (ISP) via IEEE Std. 1149.1 JTAG and includes boundary-scan test circuitry. The component is housed in a TQFP-100 package and functions within an industrial temperature range of 0°C to +70°C.

Complex Programmable Logic Devices Procurement Notes

This specific part number is listed as discontinued by the manufacturer. Verification of current availability requires checking authorized distributors or secondary market suppliers. Users must confirm the authenticity of components sourced from non-original channels due to the end-of-life status. Design-in decisions should account for long-term supply constraints associated with obsolete programmable logic devices.

Complex Programmable Logic Devices Selection Notes

Select this component when a 3.3-V CPLD with high-speed performance (5 ns delay) and ISP capability is required. It serves as a direct pin-compatible replacement for 5.0-V MAX 7000S variants where voltage translation is managed externally. Ensure the application fits within the 128 macrocell density and 84 I/O limit. Verify that the TQFP-100 surface-mount package aligns with the PCB layout requirements.

Complex Programmable Logic Devices Part Context

The EPM7128AETC100-5 is part of the MAX 7000A series, which bridges the gap between older 5.0-V MAX 7000 devices and newer low-voltage families. It retains the proven MAX architecture while introducing native 3.3-V operation and enhanced ISP features. This series was widely adopted for legacy system upgrades and cost-sensitive digital logic implementations before being superseded by later FPGA and CPLD generations.

Complex Programmable Logic Devices Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the discontinued status, designers should evaluate modern Intel/Altera CPLD families such as MAX 10 or MAX V for new designs, ensuring functional equivalence in terms of I/O count, speed grade, and package type.
