EPM3512AQC208-10NS 概要
A CPLD (Complex Programmable Logic Device) is a non-volatile, instant-on programmable logic device that combines multiple PAL-like macro-cell blocks with a central interconnect matrix. Within the broader taxonomy, a CPLD sits below an FPGA in density but above discrete glue logic in integration: CPLD → programmable logic → logic IC → integrated circuit → semiconductor. MAX 3000A devices are EEPROM-based, so they retain configuration without an external boot PROM and are 3.3 V in-system programmable via the IEEE Std. 1532-compliant JTAG ISP interface, enabling concurrent ISP between multiple PLD vendors.
Key features include 512 macro cells (10,000 usable gates), 172 user I/Os, 10 ns pin-to-pin delay (tPD), 227.3 MHz internal counter frequency, MultiVolt I/O supporting 2.5 V/3.3 V/5.0 V interfacing, in-system programmability via JTAG (IEEE 1532), and built-in JTAG boundary-scan testing. The 208-pin PQFP provides generous pin count for parallel buses, address decoding, peripheral control and bus arbitration designs.
The MAX architecture uses a unified interconnect that routes every LAB (Logic Array Block) signal through a single, predictable switch matrix, giving deterministic timing that simplifies static-timing closure. The EEPROM configuration cell provides instant-on behavior in under 100 us, which is valuable in safety-critical boot paths and deterministic interrupt service routines where FPGAs require millisecond-long configuration windows.
Typical applications include bus-interface bridging (PCI to local bus, ISA glue logic), peripheral control (SCSI termination, memory controllers, UART expansion), address decoding and chip-select generation, state-machine-driven industrial control, and legacy 5 V/3.3 V system logic replacement. Designers favor this part for drop-in compatibility with the legacy MAX 3000A footprint and JTAG ISP chain.
When designing with this device, observe the VCCINT/VCCIO separation (3.3 V core, optional 2.5 V/3.3 V/5.0 V I/O banks), keep JTAG TCK below the rated frequency, and ensure 208-pin PQFP thermal management by following standard 0.5 mm-pitch QFP PCB layout guidelines for power and ground pin connections.

主な用途
EPM3512AQC208-10NS の用途: 6 件s: PCI-to-Local Bus Bridge, Memory Controller Chip-Select Decoder, UART and Peripheral Expansion Glue, Industrial State-Machine Controller, Legacy 5V to 3.3V Level-Shifting Bridge, JTAG-Based Boundary-Scan Test Controller.
PCI-to-Local Bus Bridge
The EPM3512AQC208-10NS is well suited as a PCI-to-local-bus bridge controller because its 172 user I/Os easily accommodate the 32-bit PCI AD/C/BE pins plus local-bus address, data and control signals. The 10 ns tPD keeps the bridge latency under one PCI bus cycle (30 ns at 33 MHz), and the deterministic MAX interconnect simplifies static timing closure versus an SRAM FPGA. According to the MAX 3000A datasheet, the MultiVolt I/O allows 3.3 V PCI signaling while the core runs on a single 3.3 V VCCINT rail. Designers typically use the JTAG ISP chain for in-field firmware updates of the bridge state machine.
おすすめ
Memory Controller Chip-Select Decoder
The EPM3512AQC208-10NS delivers 512 macro cells and 172 I/Os, which is more than sufficient to decode address ranges for SRAM, DRAM, Flash and peripheral chips on a 32-bit embedded bus. Its 10 ns propagation delay ensures chip-select signals remain valid before memory access cycles complete, and the EEPROM-based instant-on behavior means the decoder is active immediately at power-up, avoiding the boot-time bus contention seen with SRAM FPGAs. According to the MAX 3000A datasheet, MultiVolt I/O allows direct 5 V interfacing with legacy peripherals. Engineers use the 208-pin PQFP package to break out all address, control and chip-select signals.
おすすめ
UART and Peripheral Expansion Glue
The EPM3512AQC208-10NS is ideal for UART expansion, parallel-to-serial conversion, and peripheral glue logic in industrial control and test equipment. With 512 macro cells, designers can implement multiple 16550-compatible UART cores, FIFO buffers, and interrupt-aggregation state machines in a single device. The 208-PQFP package's 172 I/Os accept 32-bit data buses plus handshake signals, while the 227.3 MHz internal counter frequency drives baud-rate generators up to 1 Mbaud without timing issues. According to the MAX 3000A datasheet, JTAG ISP via IEEE 1532 allows in-field firmware updates without removing the board.
おすすめ
Industrial State-Machine Controller
The EPM3512AQC208-10NS excels as a deterministic state-machine controller for industrial automation, where its EEPROM-based instant-on architecture guarantees the controller is operational within microseconds of power-up. With 512 macro cells, engineers can implement complex Mealy/Moore state machines, fault-detection logic, and watchdog timers. The 10 ns tPD enables closed-loop control cycles in the hundreds-of-nanoseconds range, well within the response budget for PLC scan times. According to the MAX 3000A datasheet, the 0C-70C commercial temperature range is suitable for factory-floor environments with adequate thermal management.
おすすめ
Legacy 5V to 3.3V Level-Shifting Bridge
The EPM3512AQC208-10NS MultiVolt I/O makes it an excellent level-shifting bridge between legacy 5 V TTL/CMOS peripherals and modern 3.3 V processors or ASICs. With VCCIO tied to 5 V and VCCINT on 3.3 V, the same device can drive 5 V outputs and accept 3.3 V inputs, eliminating external bus-switch ICs. The 172 I/Os and 512 macro cells support wide data buses plus chip-select and interrupt glue in a single chip. According to the MAX 3000A datasheet, this mixed-voltage capability is one of the family's signature advantages for industrial retrofit designs.
おすすめ
JTAG-Based Boundary-Scan Test Controller
The EPM3512AQC208-10NS supports IEEE Std. 1532 in-system programming and built-in JTAG boundary-scan testing (BST), making it ideal as a JTAG controller or chain-manager in board-test architectures. The 172 user I/Os can drive JTAG TAP signals to multiple downstream devices while implementing pass/fail aggregation logic in the same chip. According to the MAX 3000A datasheet, the EEPROM-based non-volatile storage means test firmware is retained across power cycles without a boot PROM. Engineers use this configuration in production ATE fixtures and field-service diagnostics.

主な差別化要因
- Instant-on EEPROM-based configuration （vs SRAM-based FPGAs (e.g., Cyclone series))
- MultiVolt I/O supporting 2.5 V / 3.3 V / 5.0 V signaling （vs Single-voltage 3.3 V-only CPLDs)
- Deterministic MAX interconnect with predictable timing （vs SRAM FPGAs with variable routing delays)
設計ノート
Decouple the EPM3512AQC208-10NS VCCINT pins with one 0.1 uF ceramic capacitor per supply pin, placed within 5 mm of each PQFP pin pad. Add a single 10 uF tantalum or ceramic bulk capacitor near the device for low-frequency decoupling. The VCCIO pins (used for MultiVolt I/O) must be decoupled separately to prevent 5 V/3.3 V rail noise from coupling into the 3.3 V core. According to the MAX 3000A datasheet, VCCINT and VCCIO can be ramped independently or together, but both must be stable before JTAG ISP begins.
The 208-pin PQFP package has 0.5 mm pitch leads; route signals on 0.2 mm traces with 0.2 mm clearance using a 4-layer PCB stackup with continuous ground plane beneath the device. Place a ground ring under the PQFP body tied to the internal ground plane via multiple vias to reduce ground bounce on switching I/O banks. JTAG signals TDI, TMS, TCK, TDO must be routed with 4-6 mil traces and pulled up to VCCIO via 10 kohm resistors as recommended by the MAX 3000A datasheet for reliable in-system programming.
Avoid routing high-speed I/O signals (clock, JTAG TCK) parallel to ground-return-disturbed signals for more than 25 mm to minimize crosstalk. Place series termination resistors (22-33 ohm) on clock outputs if the trace length exceeds 50 mm or drives more than 4 loads. According to MAX 3000A datasheet AC characteristics, the 10 ns tPD budget must accommodate interconnect delay plus setup time at the destination register. Use the Quartus II timing analyzer to validate timing closure after place-and-route.
