EPM7256AETC100-7

Complex Programmable Logic Devices Overview

The Altera EPM7256AETC100-7 is a Complex Programmable Logic Device (CPLD) belonging to the MAX 7000A family. It features 256 macrocells organized into 16 Logic Array Blocks (LABs), providing approximately 5,000 usable gates. The device operates on a 3.3V supply voltage with a range of 3.0V to 3.6V and utilizes EEPROM technology for non-volatile configuration storage. Housed in a TQFP-100 surface-mount package, it offers 84 user I/O pins. Key electrical specifications include a maximum propagation delay of 5.5 ns and a maximum operating frequency of 172.4 MHz. The component supports an industrial temperature range from -40°C to +85°C.

Complex Programmable Logic Devices Feature Summary

• 256 Macrocells across 16 Logic Array Blocks (LABs)
• EEPROM-based non-volatile memory for instant-on operation
• System-in-Programmable (SIP) capability via JTAG interface
• High-speed performance with 5.5 ns max propagation delay

Complex Programmable Logic Devices Applications

• Address decoding and data bus interfacing
• State machine implementation and timing control
• Replacement for discrete logic gate arrays
• Industrial control system logic integration

Complex Programmable Logic Devices Procurement Notes

Verify RoHS compliance status as records indicate 'N' (Non-compliant) for this specific suffix variant. Confirm end-of-life (EOL) status through official Intel/Altera channels, as distribution availability is restricted. Ensure handling procedures account for moisture sensitivity classification prior to soldering.

Complex Programmable Logic Devices Selection Notes

Select this model when a 3.3V CPLD with 84 I/Os and industrial temperature rating (-40°C to +85°C) is required. Compare against EPM7256AETC100-10 if commercial temperature range (0°C to +70°C) suffices, noting the difference in propagation delay (5.5 ns vs 10 ns). Verify pin compatibility with existing TQFP-100 footprints.

Complex Programmable Logic Devices Part Context

This part belongs to the Altera MAX 7000A series, designed for high-density logic applications requiring low power and fast turnaround. It serves as a successor to earlier MAX 7000 variants, offering improved speed and density within the same footprint constraints. The EPM7256AETC100-7 specifically targets industrial environments due to its extended temperature range.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-compatible replacements are limited due to EOL status. Consider EPM7256AETC100-10 for commercial grade applications or EPM7256AEFC256-7 for higher I/O counts in FBGA packages. Validate firmware compatibility if migrating between speed grades.
