EPM240T100C3N

Complex Programmable Logic Devices Overview

The Altera EPM240T100C3N is a MAX II series Complex Programmable Logic Device (CPLD) housed in a 100-pin TQFP package. It features 240 logic elements and 192 macrocells, supporting up to 80 user I/Os. The device utilizes non-volatile Flash technology for instant-on operation without external configuration memory. Key electrical parameters include a maximum propagation delay of 4.7 ns, an internal core voltage of 2.5V, and support for 3.3V I/O banks. It operates within a commercial temperature range of 0°C to 85°C and supports In-System Programming (ISP) via JTAG.

Complex Programmable Logic Devices Feature Summary

• Non-volatile Flash architecture enabling immediate operation upon power-up.
• High-density logic with 240 LEs and 192 macrocells in a compact 100-TQFP form factor.
• MultiVolt capability allowing independent voltage domains for VCCINT (2.5V) and VCCIO (3.3V).
• Supports In-System Programming (ISP) compliant with IEEE 1532 standards.

Complex Programmable Logic Devices Applications

• Bus bridging and protocol conversion between different voltage levels.
• I/O expansion for microcontrollers and embedded systems.
• Power-On Reset (POR) generation and sequencing control.
• Device configuration management for peripheral components.

Complex Programmable Logic Devices Procurement Notes

Verify the specific speed grade suffix 'C3' against official datasheets, as standard MAX II listings often cite 'C5' (4.7ns) or 'C3' variants. Confirm RoHS compliance status and current manufacturing availability, as Intel/Altera has issued Product Change Notices regarding labeling and potential lifecycle changes for the MAX II family. Ensure the supplier provides valid traceability documentation.

Complex Programmable Logic Devices Selection Notes

Select this component when non-volatile storage is required to eliminate external configuration Flash chips, reducing BOM cost and board space. The 4.7 ns delay is suitable for moderate-speed digital logic interfacing. Compare against EPM240T100C5N if higher speed grades are needed, or EPM240M100I5N if industrial temperature ranges (-40°C to +100°C) are mandatory. Ensure design tools support Quartus II versions compatible with MAX II devices.

Complex Programmable Logic Devices Part Context

The EPM240T100C3N belongs to the Altera MAX II family, which succeeded the MAX 7000 series by integrating Flash technology. This family bridges the gap between simple PLDs and complex FPGAs, offering deterministic timing and low static power consumption. The part is manufactured using 0.18μm CMOS technology, providing a balance of performance and power efficiency for general-purpose logic applications.

Complex Programmable Logic Devices Replacement Considerations

Publicly documented pin-compatible alternatives include the AG256SL100 from AG Microelectronics. Note that while physically compatible, the AG256SL100 uses SRAM-based architecture requiring external Flash, differing from the native Flash nature of the EPM240T100C3N. Verify voltage domain handling for VCCINT pins during migration.
