EPM240GT100I5N

Complex Programmable Logic Devices Overview

The Altera EPM240GT100I5N is a MAX II series Complex Programmable Logic Device (CPLD) featuring 240 logic elements and 192 macrocells. It utilizes non-volatile Flash architecture for immediate operation upon power-up without external configuration memory. The device operates with an internal core voltage range of 1.71V to 1.89V and supports I/O banks at 1.5V, 1.8V, 2.5V, or 3.3V. Key electrical parameters include a maximum propagation delay of 4.7ns and a maximum operating frequency of 304 MHz. It offers 80 user I/Os, 4 global clocks, and 8Kbit of user-accessible Flash storage within a 100-pin TQFP package.

Complex Programmable Logic Devices Feature Summary

• Non-volatile Flash architecture enables instant-on functionality and retains configuration without power.
• Integrated 8Kbit user Flash allows storage of small data sets such as serial numbers or calibration parameters.
• Dual independent I/O voltage domains support flexible interfacing with various logic families (LVCMOS/LVTTL).
• System-in-Programmability (ISP) via JTAG interface allows in-circuit reprogramming.

Complex Programmable Logic Devices Applications

• Bus protocol conversion between different voltage levels or standards.
• Address decoding and chip select generation in embedded systems.
• Simple state machine implementation for industrial control logic.
• GPIO expansion for microcontrollers requiring additional digital inputs/outputs.

Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'GT' confirms the 100-pin TQFP package variant, distinct from MBGA options. Confirm the 'I5' designation indicates the industrial temperature range (-40°C to +100°C junction temperature). Ensure compatibility with legacy Quartus II software versions, as newer Quartus Prime releases may not support this MAX II family member. Check RoHS compliance status if environmental regulations apply to the target assembly.

Complex Programmable Logic Devices Selection Notes

Select this model when non-volatile configuration is required to eliminate external PROM components. Compare against EPM240T100I5N for identical electrical performance but verify package differences; GT denotes TQFP while T typically denotes TFBGA. Consider the 4.7ns delay limit for timing-critical paths. Evaluate power consumption requirements against the 1.8V core supply constraints. Ensure design tools support the MAX II architecture before finalizing the component choice.

Complex Programmable Logic Devices Part Context

This component belongs to the Intel (formerly Altera) MAX II family, designed for low-cost, low-power programmable logic applications. It serves as a successor to the MAX 7000 series, offering improved density and lower power consumption through 0.18μm technology. The MAX II line bridges the gap between simple fixed-function logic and high-complexity FPGAs, targeting cost-sensitive consumer and industrial electronics.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-to-pin replacements within the same package are limited to other MAX II devices with equal or greater LE counts, such as EPM240T100I5N (package difference) or EPM570 variants (higher density). Cross-family migration to MAX 10 or Cyclone IV requires significant schematic and PCB redesign due to architectural differences and pinout incompatibilities.
