EPM7256EGC192-20

Complex Programmable Logic Devices Overview

The Altera EPM7256EGC192-20 is a complex programmable logic device (CPLD) from the MAX 7000S family. It features 256 macrocells and supports up to 48 user I/Os within a 192-pin FineLine BGA package. The device operates at a maximum system clock frequency of 20 MHz, indicated by the -20 speed grade. It utilizes non-volatile Flash memory technology for configuration retention, eliminating the need for external configuration PROMs. Key electrical parameters include a supply voltage range of 3.0V to 3.6V and an operating temperature range of 0°C to 70°C for the commercial grade variant.

Complex Programmable Logic Devices Feature Summary

• 256 macrocells with 48 usable I/O pins in a 192-pin FineLine BGA package
• Non-volatile Flash memory architecture for instant-on operation without external configuration devices
• Maximum system clock frequency of 20 MHz (-20 speed grade)
• Supports high-density logic applications with low power consumption typical of CMOS technology

Complex Programmable Logic Devices Applications

• High-density logic replacement in industrial control systems
• Address decoding and bus interfacing in embedded systems
• State machine implementation for communication protocols
• Glue logic consolidation in consumer electronics hardware

Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix codes on the component marking against official Altera documentation to confirm speed grade and package type. Ensure compatibility with 3.3V logic levels when integrating into modern designs. Check for RoHS compliance status if required by current manufacturing standards. Confirm availability through authorized distributors as this is a legacy component.

Complex Programmable Logic Devices Selection Notes

Select this component when non-volatile configuration is required without external PROMs. The 256 macrocell count suits moderate complexity logic functions. The -20 speed grade limits maximum toggle rates to 20 MHz; higher performance requirements necessitate faster speed grades or different families. Ensure the 192-pin BGA footprint fits the PCB layout constraints.

Complex Programmable Logic Devices Part Context

This part belongs to Altera's MAX 7000S series, which introduced Flash memory technology to replace EEPROM-based configurations found in earlier MAX 7000 devices. It serves as a bridge between simple PAL/GAL replacements and more complex FPGAs, offering deterministic timing and non-volatility. The EGC192 designation specifies the Green Commercial grade package type.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-compatible replacements are limited due to the specific Flash architecture and package. Consider Altera MAX II or MAX V series for modern equivalents, though these require design adaptation for pinout and voltage differences. Verify that substitute components support the required 3.3V I/O levels and non-volatile configuration needs.
