EPM7128BTC100-4N

Complex Programmable Logic Devices Overview

The Altera EPM7128BTC100-4N is a high-performance, 2.5-V CMOS EEPROM-based programmable logic device (PLD) belonging to the MAX 7000B family. Built on the second-generation Multiple Array MatriX (MAX) architecture, it provides 2,500 usable gates and 128 macrocells organized into eight logic array blocks. The device features a 100-pin TQFP package with up to 100 user I/O pins. Key electrical parameters include a pin-to-pin logic delay (tPD) of 4.0 ns and a maximum counter frequency (fCNT) of 243.9 MHz. It supports advanced in-system programmability via IEEE Std. 1149.1 JTAG.

Complex Programmable Logic Devices Feature Summary

• MultiVolt I/O interface allowing compatibility with 3.3-V, 2.5-V, and 1.8-V logic levels.
• Configurable expander product terms providing up to 32 product terms per macrocell.

Complex Programmable Logic Devices Applications

• Complex digital logic replacement for SSI, MSI, and LSI functions.
• Mixed-voltage system interfacing requiring MultiVolt I/O compatibility.
• Prototyping and design iterations utilizing in-system programmability.

Complex Programmable Logic Devices Procurement Notes

Verify the specific speed grade suffix (-4) corresponds to the required 4.0 ns tPD performance. Confirm the package type matches the 100-pin Thin Quad Flat Pack (TQFP) specification. Ensure programming hardware supports the IEEE Std. 1149.1 JTAG interface for in-system programming capabilities.

Complex Programmable Logic Devices Selection Notes

Select this device when 128 macrocells and 100 I/O pins are required within a 100-pin footprint. Consider the 2.5-V core voltage with MultiVolt I/O support for mixed-voltage designs. Compare against EPM7064B or EPM7256B if gate density or I/O count requirements differ. Verify temperature range specifications against application environmental constraints.

Complex Programmable Logic Devices Part Context

The EPM7128BTC100-4N is part of the MAX 7000B family, which offers pin-compatibility with the 5.0-V MAX 7000S and 3.3-V MAX 7000A families. This allows for migration between voltage domains without redesigning the PCB layout. The device utilizes CMOS EEPROM technology, enabling reprogramming up to 100 times.

Complex Programmable Logic Devices Replacement Considerations

Pin-compatible replacements within the same package include other MAX 7000B devices such as EPM7064B or EPM7256B, subject to density requirements. Cross-family migration to MAX 7000A (3.3-V) or MAX 7000S (5.0-V) is possible due to pin compatibility, but voltage level differences must be addressed.
