EPM240T100C3N Ringkasan

The Altera (now Intel) EPM240T100C3N is a member of the MAX II family of low-power, non-volatile CPLDs (Complex Programmable Logic Devices), providing 240 Logic Elements (LEs), 192 macrocells, and 80 user I/O pins in a 100-pin TQFP package. It features instant-on non-volatile Flash configuration memory, in-system programmability via JTAG, and support for multiple I/O standards including 1.5 V, 1.8 V, 2.5 V, 3.3 V LVCMOS/LVTTL.

A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that sits between simple PAL/GAL devices and larger FPGAs in the programmable logic hierarchy (PAL/GAL -> CPLD -> FPGA -> ASIC). Unlike SRAM-based FPGAs, MAX II CPLDs store their configuration in on-chip Flash, so they boot instantly without an external configuration PROM and retain their bitstream through power cycles. They are typically used for glue logic, bus bridging, power-up sequencing, and state-machine replacement where deterministic timing, low power, and instant-on behavior matter more than density.

Key features include 8 Kbits of user Flash memory (UFM), 4.4 ns pin-to-pin logic delay (tPD), 200 MHz internal oscillator, and a MultiVolt I/O interface. The device operates from a single 3.3 V core supply with separate VCCIO banks for mixed-voltage interfacing, consumes only 35 mA typical quiescent current, and supports commercial temperature range (0 °C to +85 °C).

The MAX II architecture combines a continuous interconnect fabric with Logic Array Blocks (LABs), each containing 10 Logic Elements. This non-volatile, instant-on approach eliminates the boot/configuration overhead of SRAM FPGAs, making the EPM240T100C3N a deterministic, low-power solution for high-volume glue-logic applications.

Typical applications include I/O expansion and bus bridging, power-supply sequencing and supervisory logic, LED display driving, industrial control interfaces, and bootloader/reset management for FPGAs and microprocessors. The 80 user I/O pins provide flexible interfacing to parallel buses and digital sensor arrays.

When designing with this device, allocate sufficient VCCIO decoupling (100 nF plus 10 µF bulk) at each bank, and verify JTAG chain integrity before relying on in-system programming. Designers migrating from older MAX 7000-series parts should review the MultiVolt core/I/O split and ensure 3.3 V core rails are present.
