EPM240T100C5 - MAX II CPLD, 192 Macrocells, 100-TQFP | Altera
MPN: EPM240T100C5 ✓ Hoạt độngEPM240T100C5 Tóm tắt
A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that uses a macrocell-based architecture with continuous, distributed interconnect. In the system-level hierarchy, a CPLD sits below an FPGA (Field-Programmable Gate Array) in density, above small PAL/GAL devices, and below microcontroller units (MCUs) in flexibility. MAX II CPLDs target glue-logic, interface bridging, power-sequencing, and bus-management functions where deterministic timing and zero in-system configuration delay are mandatory.
Key features include 192 logic elements, 4.7 ns pin-to-pin logic delay (tPD1), 201.1 MHz maximum internal operating frequency, support for 2.5 V and 3.3 V core supply operation, MultiVolt I/O supporting 1.5 V/1.8 V/2.5 V/3.3 V levels, JTAG-based IEEE 1149.1 boundary-scan testing and in-system programmability (ISP), and a global chip-wide DEV_OE output enable pin for board-level tri-state control.
The device uses a non-volatile Flash-based architecture with 8 Kbits of embedded storage, four I/O banks for voltage-domain isolation, and on-chip pull-up resistors (User I/O pin 4 control) configurable in Quartus II. Each macrocell contains a programmable AND/OR array, a flip-flop, and feedback paths to the logic array, enabling compact state-machine and decoding-logic implementation.
Typical applications include I/O expansion for microcontrollers and microprocessors, address decoding and chip-select generation in memory subsystems, bus-interface bridging (LVCMOS, LVTTL, PCI-compatible), power-supply sequencing in multi-rail systems, and configurable glue logic in industrial automation equipment. The instant-on behavior also suits FPGA configuration control, where the CPLD provides boot-up housekeeping before the main FPGA completes its configuration cycle.
When designing with the EPM240T100C5, observe I/O bank voltage constraints: each of the four banks shares a common VCCIO that must match the signal level of devices connected to that bank. The 5.0-V tolerant I/O feature requires VCCIO at 3.3 V; do not apply 5 V to any I/O pin. Use Quartus II (legacy) or the Intel Quartus Prime Lite Edition for design entry, synthesis, and JTAG programming.

Ứng dụng tiêu biểu
EPM240T100C5 phù hợp cho 6 Áp dụngs: Microcontroller I/O Expansion and Glue Logic, Power Supply Sequencing in Multi-Rail Systems, FPGA Configuration and Boot Control, Bus Interface Bridging (LVCMOS, LVTTL, PCI), Industrial Automation Control Logic, Address Decoding in Memory Subsystems.
Microcontroller I/O Expansion and Glue Logic
The EPM240T100C5 expands a host MCU's limited GPIO by decoding address lines and generating chip-select strobes for peripherals like SRAM, Flash, and sensors. Its 192 macrocells and 80 user I/O pins provide ample headroom for 8-bit and 16-bit bus decoding, while the 4.7 ns pin-to-pin delay ensures address-to-CS propagation stays well under one 50 MHz system clock period. The instant-on non-volatile Flash eliminates boot-PROM overhead, so the CPLD is ready to drive chip-selects before the MCU finishes its PLL lock - critical for deterministic power-on behavior. Designers typically place the CPLD between the MCU EMI bus and 4-8 peripheral devices, freeing the MCU's GPIO for serial interfaces.

Power Supply Sequencing in Multi-Rail Systems
The EPM240T100C5 sequences 3-6 voltage rails (1.0 V core, 1.5 V DDR, 1.8 V I/O, 2.5 V PLLs, 3.3 V analog) in the correct order during power-up and reverse order during power-down. Each macrocell implements a comparator-and-counter state machine that watches a PGOOD signal and asserts the next rail's enable after a configurable delay. The non-volatile Flash means the sequencing logic is active within microseconds of VCCINT reaching 2.5 V, eliminating the race condition between bulk-capacitor charging and rail-monitors. Designers typically route 4 power-good inputs to the CPLD and 6 enable outputs to DC-DC converter PG pins.
Được đề xuất
FPGA Configuration and Boot Control
The EPM240T100C5 acts as a configuration controller for SRAM-based FPGAs that require multi-mode boot (JTAG / parallel / serial). It reads the FPGA's configuration mode-pins and drives them based on a user-defined mode sequence, holds the FPGA in RESET until VCCINT is stable, and generates the PROG_B pulse on demand. The 8 Kbit embedded Flash stores the mode-selection logic permanently, so no external PROM is needed. Designers route DONE, INIT_B, and CONFIG_B lines from the FPGA to the CPLD, with the CPLD returning CTRL0/CTRL1 selections. This pattern is common in industrial and telecom designs where field-upgrade flexibility is required.
Được đề xuất
Bus Interface Bridging (LVCMOS, LVTTL, PCI)
The EPM240T100C5 bridges between mismatched bus standards - for example, translating a 3.3 V LVCMOS microcontroller bus to 1.8 V LVCMOS peripherals or providing a 5-V-tolerant input buffer for legacy PCI signals (when VCCIO is set to 3.3 V). Four I/O banks allow voltage-domain isolation so 1.5 V, 1.8 V, 2.5 V, and 3.3 V devices can all connect to the same CPLD without external level-shifters. With 4.7 ns tPD, the bridge introduces negligible latency into memory-mapped interfaces. Typical designs use 8-16 macrocells per 8-bit bus-converter instance, leaving headroom for handshaking and parity logic.
Được đề xuất
Industrial Automation Control Logic
In factory-automation PLCs, distributed I/O blocks, and motor-control auxiliary boards, the EPM240T100C5 implements deterministic state machines for safety-interlock logic, encoder-decoder counting, and PWM-edge multiplexing. Its 0-85C commercial or -40-85C industrial variants and 4.7 ns tPD suit real-time control loops. The on-chip pull-up resistors (configurable per User I/O pin 4) reduce BOM cost by eliminating external 10K arrays. Designers typically deploy 1-2 CPLDs per PLC chassis to consolidate discrete logic that would otherwise require dozens of 74HC-series gates.
Được đề xuất
Address Decoding in Memory Subsystems
The EPM240T100C5 decodes 24-32 bit address lines into individual chip-selects for Flash, SRAM, DRAM, and peripheral registers in embedded systems. A typical implementation uses 32 macrocells to generate 8 chip-selects with address-range masking via internal feedback comparators. The instant-on behavior ensures the chip-selects are valid at the first clock edge after reset, eliminating the boot-window violation that occurs with SRAM-based FPGAs. Designers often combine this application with bus-cycle termination logic (RDY/BWAIT stretching) using the same CPLD, saving board area versus discrete MSI logic.

Ghi chú thiết kế
Decouple each VCCINT and VCCIO pin with a 0.1 µF ceramic capacitor placed within 5 mm of the respective pin and a 10 µF bulk tantalum or ceramic capacitor at the board-level supply rail. The four VCCIO banks allow mixed-voltage operation (1.5 V / 1.8 V / 2.5 V / 3.3 V) but each bank must share a common voltage; do not drive signals between different VCCIO domains without series resistors or level shifters if voltage mismatch exceeds 0.3 V.
The 100-pin TQFP has a 0.5 mm pitch and 14 mm × 14 mm body - use 4-mil (0.1 mm) traces between pads with 8-mil (0.2 mm) clearance for escape routing. Place a continuous ground plane on the layer directly beneath the device to minimize ground bounce on the JTAG and DEV_OE pins. Route JTAG signals (TDI, TMS, TCK, TDO) in a daisy-chain with 10K pull-ups on TDI/TMS/TCK as recommended in the MAX II handbook.
When using the EPM240T100C5 for high-speed address decoding or bus-bridging, observe 50 ohm controlled-impedance routing on outputs driving more than 25 mm of trace. Source-synchronous clocks should be assigned to dedicated clock input pins and use the on-chip PLL-free global clock network - the MAX II does not contain a PLL, so clock multiplication must be implemented in the macrocell fabric. Add 22-33 ohm series damping resistors on outputs driving backplane connectors to suppress ringing.
Do not apply 5.0 V to any I/O pin when VCCIO is set to less than 3.3 V - the absolute-maximum VCCIO+0.3 V input rating applies, and 5 V tolerance requires VCCIO = 3.3 V. Do not leave JTAG pins floating during in-system operation; floating TMS or TCK can inadvertently trigger boundary-scan operations. Verify that the Quartus II .pof programming file matches the target device ID before JTAG programming - using a C5 image on a C4 device will fail verification.
