EPM3128ATC144-7

Complex Programmable Logic Devices Overview

The Altera EPM3128ATC144-7 is a Complex Programmable Logic Device (CPLD) belonging to the MAX 3000A family. It features 2,500 usable gates and 128 macrocells organized into eight logic array blocks. The device operates at a maximum frequency of 192.3 MHz with a typical pin-to-pin propagation delay of 5 ns. It utilizes a 3.3-V supply voltage and supports in-system programming via an IEEE Std. 1149.1 JTAG interface. The component is housed in a 144-pin Thin Quad Flat Pack (TQFP) package and includes MultiVolt I/O compatibility for 2.5-V, 3.3-V, and 5.0-V logic levels.

Complex Programmable Logic Devices Procurement Notes

Verify the specific speed grade suffix (-7) against the datasheet Table 2 to confirm availability within the MAX 3000A product line. Ensure the TQFP-144 package matches the required PCB footprint. Check for end-of-life status or obsolescence notices from the manufacturer before finalizing procurement plans.

Complex Programmable Logic Devices Selection Notes

Select this component when designs require up to 128 macrocells and 96 user I/O pins in a 144-pin package. The -7 speed grade offers a 5 ns delay suitable for moderate-speed applications. Consider the -5 or -4 grades if faster switching speeds are necessary, or the -10 grade for lower power consumption requirements.

Complex Programmable Logic Devices Part Context

This part is a member of the Altera MAX 3000A family, which ranges from 600 to 10,000 usable gates. The EPM3128A variant specifically provides 2,500 gates and 128 macrocells. Other variants in the series include EPM3032A, EPM3064A, EPM3256A, and EPM3512A, offering different densities and pin counts.

Complex Programmable Logic Devices Replacement Considerations

Compatible alternatives within the same family include EPM3128ATC144-5 and EPM3128ATC144-10. These parts share identical pinouts and functionality but differ in speed grades and timing characteristics. Verify that the replacement meets the specific timing constraints of the original design.
