EPM7128BTC100-7N

Complex Programmable Logic Devices Overview

The Altera EPM7128BTC100-7N is a high-performance, 2.5-V CMOS EEPROM-based programmable logic device (PLD) belonging to the MAX 7000B family. It utilizes the second-generation Multiple Array MatriX (MAX) architecture and features 128 macrocells with 2,500 usable gates. The device operates in a 100-pin TQFP package and supports 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 provides advanced 2.5-V in-system programmability via an IEEE Std. 1149.1 JTAG interface.

• MultiVolt I/O interface supporting 3.3-V, 2.5-V, and 1.8-V logic levels.
• Built-in boundary-scan test circuitry compliant with IEEE Std. 1149.1.

Complex Programmable Logic Devices Applications

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

Complex Programmable Logic Devices Procurement Notes

Verify the specific speed grade suffix (-7) against current manufacturer availability lists, as older MAX 7000B variants may have limited production status. Confirm package integrity for the 100-pin TQFP form factor. Ensure programming hardware supports the enhanced ISP algorithm and IEEE Std. 1532 compliance for in-system configuration.

Complex Programmable Logic Devices Selection Notes

Select this device when a 2.5-V core voltage is required alongside mixed-voltage I/O capabilities. Compare tPD of 4.0 ns and fCNT of 243.9 MHz against timing requirements. Consider pin-compatibility with MAX 7000S and MAX 7000A families if migrating from 5.0-V or 3.3-V designs. Verify that the 100-pin TQFP package meets board space constraints.

Complex Programmable Logic Devices Part Context

This component is part of the MAX 7000B family, which succeeded the MAX 7000A series. It offers lower power consumption due to its 2.5-V operation compared to previous generations. The family supports SameFrame pin-outs for BGA packages, though this specific unit uses a TQFP package. It is designed for applications requiring reprogrammable logic with fast turnaround 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 and I/O count requirements. Cross-family migration to MAX 7000A (3.3-V) or MAX 7000S (5.0-V) requires voltage level adjustment and potential software recompilation.
