EPM240T100I5NAB

Complex Programmable Logic Devices Overview

The Altera EPM240T100I5NAB is a MAX II series Complex Programmable Logic Device (CPLD) featuring 240 logic elements and 192 macrocells. It utilizes a non-volatile Flash architecture for instant-on operation without external configuration memory. The device supports up to 80 user I/Os with MultiVolt capabilities, allowing independent voltage domains of 1.5V, 1.8V, 2.5V, or 3.3V. Key electrical parameters include a maximum propagation delay of 4.7ns and an internal kernel voltage of 2.5V. It operates within an industrial temperature range of -40°C to +100°C and is housed in a 100-pin TQFP package.

Complex Programmable Logic Devices Feature Summary

• Non-volatile Flash architecture enabling instant power-up and no external configuration chip requirement
• MultiVolt I/O banks supporting 1.5V, 1.8V, 2.5V, and 3.3V levels independently
• Industrial temperature rating (-40°C to +100°C) for robust environmental performance
• System In-Programmability (ISP) via JTAG interface for field updates

Complex Programmable Logic Devices Applications

• Bus bridging and protocol conversion between different voltage domains
• I/O expansion for microcontrollers and processors
• Power-on reset sequencing and timing control
• Logic glue for embedded system interconnects

Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'AB' against official Intel/Altera documentation, as standard listings typically use 'N' for lead-free compliance. Confirm the package type matches the required PCB footprint, as TQFP dimensions differ significantly from MBGA variants. Ensure design tools are compatible with the MAX II family, noting that newer Quartus Prime versions may have limited support compared to legacy Quartus II environments.

Complex Programmable Logic Devices Selection Notes

Select this component when non-vatility and instant-on functionality are critical, eliminating the need for external configuration Flash. Choose the TQFP package if through-hole or larger surface-mount spacing is preferred over BGA. Verify that the 240 LE count is sufficient for the target logic complexity, as higher density options exist within the MAX II family for more complex designs.

Complex Programmable Logic Devices Part Context

This part belongs to the Intel (formerly Altera) MAX II family, designed as a low-cost, low-power replacement for older GALs and PLDs. The MAX II series bridges the gap between simple discrete logic and high-complexity FPGAs, offering deterministic timing and ease of use for small-scale digital logic applications.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-to-pin replacements within the same package and speed grade should be sought from the MAX II family, such as the EPM240T100C5NAC for commercial grade or EPM240T100I5N for industrial grade. Cross-family migration to MAX V or Cyclone IV requires significant schematic and code redesign due to architectural differences.
