EPM7256AETI100-7N

Complex Programmable Logic Devices Overview

The Altera EPM7256AETI100-7N is a Complex Programmable Logic Device (CPLD) belonging to the MAX 7000AE family. It features 256 macrocells organized into 16 Logic Array Blocks (LABs), providing approximately 5,000 usable gates. The device operates at a supply voltage of 3.3V (range 3.0V to 3.6V) and offers 84 I/O pins. Key electrical parameters include a maximum propagation delay of 5.5 ns and a maximum operating frequency of 172.4 MHz. It utilizes EEPROM technology for non-volatile configuration and is housed in a TQFP-100 surface-mount package.

Complex Programmable Logic Devices Procurement Notes

Verify component authenticity due to the device's end-of-life status. Confirm RoHS compliance details as specifications may vary by manufacturing batch. Ensure handling procedures account for moisture sensitivity classification during soldering processes.

Complex Programmable Logic Devices Selection Notes

Select this model when 256 macrocells are sufficient for the design logic. The 5.5 ns speed grade is suitable for applications requiring deterministic timing under 172.4 MHz. Choose the TQFP-100 package if board space allows for its footprint while retaining through-hole compatible pin spacing for prototyping flexibility.

Complex Programmable Logic Devices Part Context

This part is a variant within the Altera MAX 7000AE series, distinguished by the 'TI' suffix indicating the TQFP-100 package and '-7N' denoting the specific speed grade and commercial/industrial temperature range options. It succeeds earlier MAX 7000 variants with improved density and speed characteristics.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-compatible replacements are limited due to the end-of-life status. Consider Intel MAX 10 or Cyclone V families for new designs, though these require significant schematic and layout modifications.
