EPM7256BTC100-10N

Complex Programmable Logic Devices Overview

The Altera EPM7256BTC100-10N 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 5,000 usable gates and 256 macrocells organized into 16 Logic Array Blocks (LABs). The device features a pin-to-pin logic delay of 5.0 ns and supports counter frequencies up to 188.7 MHz. It includes advanced in-system programmability via an IEEE Std. 1149.1 JTAG interface and supports MultiVolt I/O for compatibility with 3.3-V, 2.5-V, and 1.8-V logic levels.

Complex Programmable Logic Devices Feature Summary

• High-density PLD with 256 macrocells, 16 LABs, and 5,000 usable gates.
• Advanced 2.5-V in-system programmability (ISP) using IEEE Std. 1149.1 JTAG.
• MultiVolt I/O interface supporting 3.3-V, 2.5-V, and 1.8-V logic levels.
• Configurable expander product terms allowing up to 32 product terms per macrocell.

Complex Programmable Logic Devices Applications

• Complex digital logic replacement for PALs, GALs, and pLSI devices.
• Mixed-voltage system integration requiring voltage translation between 3.3-V, 2.5-V, and 1.8-V domains.
• High-speed sequential and combinatorial logic functions with predictable timing performance.

Complex Programmable Logic Devices Procurement Notes

Verify that the specific ordering suffix corresponds to the required package type and speed grade. Confirm compliance with relevant environmental standards such as RoHS if applicable to the manufacturing batch. Ensure programming hardware supports the IEEE Std. 1532 specification for ISP operations.

Complex Programmable Logic Devices Selection Notes

Select this device when designs require 256 macrocells and 2.5-V core operation with mixed-voltage I/O capabilities. Compare against MAX 7000A or MAX 7000S families if 3.3-V or 5.0-V supply voltages are mandatory. Consider the 100-pin TQFP package constraints regarding pin count and thermal dissipation for the target application.

Complex Programmable Logic Devices Part Context

This component is part of the MAX 7000B family, which succeeded the MAX 7000A series. It offers enhanced performance and lower power consumption compared to previous generations while maintaining pin compatibility with select devices in other MAX 7000 variants. The family utilizes CMOS EEPROM technology for non-volatile configuration storage.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-compatible replacements within the same package include other MAX 7000B devices such as the EPM7128B or EPM7512B, subject to density requirements. Cross-family migration to MAX 7000A or MAX 7000S requires voltage level verification and potential board redesign due to different supply voltage specifications.
