EPM240T100C3 - MAX II CPLD, 192 Macrocells, TQFP-100 | Intel
MPN: EPM240T100C3 ✓ Hoạt độngEPM240T100C3 Tóm tắt
What is a CPLD? A Complex Programmable Logic Device is a non-volatile, flash- or EEPROM-backed programmable logic device that sits between simple PAL/GAL SPLDs and FPGAs in the programmable logic hierarchy. Compared to FPGAs, CPLDs offer instant-on configuration (no external boot PROM), deterministic timing with predictable pin-to-pin propagation delays, and excellent general-purpose I/O density at lower cost. They are widely used for I/O expansion, bus bridging, power-up sequencing, address decoding, and logic integration on cost-sensitive boards where FPGAs would be overkill.
The EPM240T100C3 specifically belongs to the MAX II G (Green) family and features Instant-On capability, MultiVolt I/O support for 1.5 V, 1.8 V, 2.5 V, and 3.3 V interfaces, and a built-in User Flash Memory (UFM) block. Designers can also benefit from Altera/Intel Quartus II design software support, a generous JTAG-based ISP interface, and pin-compatible migration to higher-density MAX II devices like the EPM570 and EPM1270.
Typical applications include I/O voltage translation and level shifting in mixed-voltage designs, bus multiplexing and address decoding for microprocessors and DSPs, configuration and control logic for FPGAs and SoCs, board-level glue logic replacing discrete 74-series gates, and digital signal conditioning or interface bridging between peripheral ICs. The wide I/O count and tolerant MultiVolt inputs make it well suited to industrial control, motor drive, and embedded computing motherboards.
When designing with this device, ensure that I/O bank voltage rails match the connected peripherals; the UFM block is limited to approximately 8 Kbits of non-volatile storage and requires careful write/erase cycle management. Designers should also plan for the JTAG chain when multiple programmable devices share the same boundary-scan bus.

Ứng dụng tiêu biểu
EPM240T100C3 phù hợp cho 6 Áp dụngs: I/O Voltage Translation and Level Shifting, Bus Multiplexing and Address Decoding, FPGA / SoC Configuration and Control Logic, Board-Level Glue Logic Replacement, Industrial Control and Motor Drive Logic, Digital Interface Bridging and Protocol Conversion.
I/O Voltage Translation and Level Shifting
The EPM240T100C3 with MultiVolt I/O support for 1.5 V, 1.8 V, 2.5 V, and 3.3 V rails on a single 2.5 V / 3.3 V core is an ideal level translator between mixed-voltage peripherals on a modern motherboard. A typical use case bridges a 3.3 V microcontroller to 1.8 V DDR memory or 1.5 V legacy ASICs without external translator ICs, reducing BOM cost by 30-50%. Its non-volatile instant-on configuration means level-shift mappings are available at power-up with zero software loading delay, which is critical for boot sequencing in processor-based designs. The 80 user I/Os provide abundant channels for wide data buses.
Được đề xuất
Bus Multiplexing and Address Decoding
The EPM240T100C3's 192 macrocells and instant-on flash configuration make it ideal for address decoding, chip-select generation, and bus multiplexing in microprocessor and DSP systems. With deterministic pin-to-pin propagation delay (a hallmark of CPLDs versus FPGAs), the device generates clean, glitch-free chip enables well before any software boot, supporting legacy peripherals and memory windows. A common deployment uses the CPLD to arbitrate between an SDRAM controller and an external bus, eliminating the need for 74-series decoder gates and shrinking board area while improving timing margins.
Được đề xuất
FPGA / SoC Configuration and Control Logic
The EPM240T100C3 frequently sits next to a larger FPGA or SoC as a configuration supervisor, glue-logic controller, or peripheral manager. Its non-volatile flash memory and JTAG ISP let it store board-revision IDs, MAC addresses, or boot straps in the 8-Kbit User Flash Memory block without an external EEPROM. The CPLD can reset, configure, and monitor an FPGA while exposing status LEDs, fan PWM, and I2C peripherals on 80 MultiVolt-tolerant I/O pins. This design pattern is common in telecom line cards, industrial controllers, and FPGA-based PCIe boards where deterministic startup behavior is mandatory.
Được đề xuất
Board-Level Glue Logic Replacement
Engineers replace dozens of 74HC / 74LVC discrete logic gates with a single EPM240T100C3 to consolidate address decoding, parity generation, interrupt prioritization, and reset distribution. The 192 macrocells (240 LEs) absorb roughly 30 to 50 standard SSI / MSI packages, dramatically reducing PCB area, lowering power consumption, and eliminating timing skew between discrete gates. The TQFP-100 footprint fits on existing 74-series land patterns with no board rework, and the Quartus design entry captures schematics that document the logic, easing long-term maintenance.
Được đề xuất
Industrial Control and Motor Drive Logic
In industrial automation, the EPM240T100C3 integrates encoder interfaces, PWM generation, fault handling, and safe-torque-off logic in a single deterministic CPLD. With 80 user I/Os and MultiVolt tolerance, the part directly interfaces 3.3 V MCUs and 5 V gate drivers through external level shifters, while the 0C to +85C commercial temperature range suits factory-floor enclosures. Designers benefit from instant-on startup for deterministic motor-brake engagement, plus a non-volatile configuration that survives brown-outs without external boot PROMs or watchdogs.
Được đề xuất
Digital Interface Bridging and Protocol Conversion
The EPM240T100C3 bridges legacy parallel buses (e.g., 8/16-bit microcontrollers, SRAM, or ASIC registers) to modern serial interfaces such as SPI, I2C, or UART. Designers implement state machines in Verilog or VHDL, compile with Quartus, and program the CPLD via JTAG to create a custom protocol converter with deterministic latency measured in single-digit nanoseconds. With 80 I/Os and an 8-Kbit UFM, the device can also store device IDs, calibration constants, or configuration scripts alongside the logic - eliminating external EEPROMs in compact embedded designs.

Ghi chú thiết kế
The EPM240T100C3 requires both a core supply (VCCINT, 2.5 V or 3.3 V) and per-bank I/O supplies (VCCIO1 through VCCIO4) for MultiVolt operation. Decouple each VCC pin with a 0.1 uF ceramic capacitor as close to the package as possible, and add a bulk 10 uF tantalum or polymer cap on each supply rail. Tie all VCCIO pins in a given bank to the same voltage; mixing voltages within a single bank is not supported by the MAX II architecture and may damage the I/O cells or cause logic errors.
The TQFP-100 (14x14 mm, 0.5 mm pitch) package requires careful PCB layout: use 0.20 mm-wide traces between pins, a 4-layer stack-up with dedicated ground and power planes, and via-in-pad or fan-out vias for clean signal integrity. The MAX II datasheet recommends thermal relief pads on all VCC/GND pins to ease rework, plus a continuous ground plane beneath the device to minimize EMI from the 80 high-speed I/O drivers. Length-match clock and JTAG signals to within 50 mils to avoid setup/hold violations.
Three common pitfalls with the EPM240T100C3: (1) Forgetting that the User Flash Memory (UFM) is only ~8 Kbits and has limited write/erase endurance - do not use it for high-cycle counters. (2) Treating the CPLD as hot-swappable - VCCINT and VCCIO must be ramped together within datasheet limits to avoid latch-up. (3) Confusing the JTAG chain with a microprocessor debug port - the MAX II JTAG pins (TDI/TDO/TMS/TCK) only support boundary scan and ISP, not in-system debugging of external processors.
Although the MAX II is non-fabric-based (instant-on), the 80 LVCMOS I/Os can still produce significant simultaneous switching noise (SSN). Decouple each VCCIO bank with at least 0.1 uF per pin and one bulk cap per bank; place series resistors (22-33 ohm) on high-frequency outputs to dampen reflections. For MultiVolt interfacing, ensure that any 5 V input signal is properly clamped or level-shifted, as the absolute-maximum VCCIO is 3.6 V and over-voltage can permanently damage the I/O cells.
