EPM7128BTC100-7

Complex Programmable Logic Devices Overview

The Altera EPM7128BTC100-7 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 supports up to 100 user I/O pins in a 100-pin TQFP package. Key electrical parameters include a pin-to-pin logic delay (tPD) of 4.0 ns, a setup time (tSU) of 2.5 ns, and maximum counter frequencies (fCNT) of 243.9 MHz.

Complex Programmable Logic Devices Feature Summary

• Advanced 2.5-V in-system programmability (ISP) via IEEE Std. 1149.1 JTAG interface with enhanced algorithms and ISP_Done bit.
• MultiVolt I/O interface allowing compatibility with 3.3-V, 2.5-V, and 1.8-V logic levels while the core operates at 2.5 V.
• High-density integration with 128 macrocells organized into 8 Logic Array Blocks (LABs) and a Programmable Interconnect Array (PIA).
• Support for advanced I/O standards including SSTL-2, SSTL-3, and GTL+, along with bus-hold and open-drain options.

Complex Programmable Logic Devices Applications

• Complex digital logic replacement for PALs, GALs, and pLSI devices.
• Mixed-voltage system interfacing requiring MultiVolt I/O compatibility.
• High-speed counter applications operating up to 243.9 MHz.
• Designs requiring in-system reprogrammability for field upgrades or debugging.

Complex Programmable Logic Devices Procurement Notes

Verify the specific speed grade suffix (-7) corresponds to the required 4.0 ns tPD performance. Confirm the package type matches the 100-pin Thin Quad Flat Pack (TQFP) outline. Ensure design tools support the MAX 7000B family for compilation and programming.

Complex Programmable Logic Devices Selection Notes

Select this device when 128 macrocells and 100 I/O pins are sufficient for the design logic density. Consider the 2.5-V core voltage requirement and ensure power supplies align with the MultiVolt I/O capabilities. Compare against MAX 7000A or MAX 7000S families if 3.3-V or 5.0-V operation is strictly required instead of 2.5-V.

Complex Programmable Logic Devices Part Context

The EPM7128BTC100-7 is part of the MAX 7000B family, which offers pin-compatibility with the popular 5.0-V MAX 7000S and 3.3-V MAX 7000A device families. This allows for potential migration paths between voltage domains without redesigning the PCB footprint, provided the package type remains consistent.

Complex Programmable Logic Devices Replacement Considerations

Pin-compatible alternatives within the same package include other MAX 7000B devices such as EPM7064B or EPM7256B, subject to logic density requirements. Cross-family replacements like MAX 7000A or MAX 7000S may require voltage level adjustments but maintain physical pin compatibility.
