EPM7128STC100-10F

Complex Programmable Logic Devices Overview

The Altera EPM7128STC100-10F is a MAX 7000S series Complex Programmable Logic Device (CPLD) housed in a 100-pin Thin Quad Flat Pack (TQFP). It features 128 macrocells, 2,500 usable gates, and 100 user I/O pins. The device operates at a maximum frequency of 147.1 MHz with a typical pin-to-pin propagation delay of 6 ns. It supports 5.0-V in-system programmability via an IEEE Std. 1149.1 JTAG interface and includes built-in boundary-scan test circuitry. The 'F' suffix indicates the device was tested using a constant algorithm for ISP compatibility.

Complex Programmable Logic Devices Procurement Notes

Verify that the ordering suffix 'F' corresponds to the constant algorithm testing method required by specific in-circuit testers. Confirm package dimensions for the 100-pin TQFP form factor. Ensure design tools support the MAX 7000S architecture for proper compilation and verification.

Complex Programmable Logic Devices Selection Notes

Select this model when 5.0-V ISP and JTAG BST are required. Compare against EPM7128E if ISP is not needed. Check Table 3 for speed grade availability (-10). Verify MultiVolt I/O requirements as it is not available in 44-pin packages, though this is a 100-pin part.

Complex Programmable Logic Devices Part Context

Part of the MAX 7000 family based on second-generation MAX architecture. Fabricated with CMOS EEPROM technology. Supports reprogramming up to 100 times. Compatible with Altera development systems including MAX+PLUS II and Quartus.

Complex Programmable Logic Devices Replacement Considerations

Pin-compatible with low-voltage MAX 7000A and MAX 7000B devices. Consider EPM7128AE or EPM7128BE for 3.3-V or 2.5-V operation respectively, noting voltage level differences.
