EPM240GT100C3

Complex Programmable Logic Devices Overview

The Altera EPM240GT100C3N is a MAX II series Complex Programmable Logic Device (CPLD) housed in a 100-pin TQFP package. It features 240 logic elements organized into 24 Logic Array Blocks and provides 192 macrocells with 80 available I/Os. The device operates on an internal 1.8V supply (range 1.71V to 1.89V) and supports JTAG in-system programming via non-volatile Flash memory. Key electrical specifications include a maximum propagation delay of 4.7 ns, a maximum operating frequency of 304 MHz, and a total user memory capacity of 8192 bits.

Complex Programmable Logic Devices Feature Summary

• Non-volatile Flash architecture allows immediate operation upon power-up without external configuration devices.
• Integrated 8Kbit user-accessible Flash memory for storing small data sets or configuration parameters.
• Dual voltage domain support enabling independent VCCIO configurations for different I/O standards.
• System-in-Programmability (SIP) capability via JTAG interface for field updates.

Complex Programmable Logic Devices Applications

• Logic level translation between disparate voltage domains.
• Bus protocol conversion and interface bridging.
• General-purpose glue logic for embedded systems.
• Address decoding and simple state machine implementation.

Complex Programmable Logic Devices Procurement Notes

Verify the suffix 'N' indicates lead-free RoHS compliance. Confirm the temperature grade 'C' corresponds to the commercial range of 0°C to +70°C. Ensure the design accounts for Moisture Sensitivity Level 3 (MSL 3), requiring appropriate storage and reflow profile adherence during assembly.

Complex Programmable Logic Devices Selection Notes

Select this component when non-volatile configuration is required to eliminate external Flash chips. The 100-TQFP package is suitable for surface-mount applications where moderate pin density is needed. Verify that the 4.7 ns delay meets timing constraints for the target clock frequencies.

Complex Programmable Logic Devices Part Context

This part belongs to the Intel (formerly Altera) MAX II family, designed as a low-power successor to the MAX 7000 series. It utilizes a 0.18μm process technology. Development requires Quartus II software versions up to 13.1, as newer Quartus Prime versions do not support this legacy family.

Complex Programmable Logic Devices Replacement Considerations

Public documentation identifies the AGM AG256SL100 as a pin-compatible alternative offering similar functionality in a TQFP-100 package. Note that internal power pin mappings may differ, requiring schematic review.
