EPM3512AFC256-7N 概要
What is a CPLD? A Complex Programmable Logic Device is a non-volatile programmable logic device that combines multiple PAL/GAL-style macrocell arrays with a central interconnect matrix, providing fast deterministic propagation delays, predictable timing, and instant-on behavior from on-chip EEPROM. CPLDs sit between simple SPLDs/GALs and large SRAM-based FPGAs in the programmable logic taxonomy: SPLD < CPLD < FPGA. The MAX 3000A family uses 3.3V core supply with multi-voltage VCCIO support for mixed 3.3V/2.5V I/O interfacing.
Key features include in-system programmability compliant with IEEE Std. 1532 (concurrent ISP across vendors), a 116.3 MHz internal fMAX, 5V-tolerant I/O pins, JTAG boundary-scan test support, and programmable power-saving modes per macrocell. The 256-pin FBGA (1.0 mm pitch, FineLine BGA) package provides dense I/O with controlled-impedance signal paths suitable for high-speed glue-logic applications.
The EPM3512AFC256-7N is built on a 0.30 micrometer CMOS EEPROM process with a 4-wire JTAG interface and a MultiVolt I/O architecture. Its deterministic timing model allows software tools (Quartus II / MAX+PLUS II) to compute exact worst-case fMAX before fabrication, eliminating timing closure iterations common with SRAM FPGAs.
Typical applications include bus interface bridging, address decoding and glue logic, peripheral I/O expansion, state-machine controllers, and system-level reset/sequencing blocks in telecom, industrial, and consumer products. The 208 user I/Os make it especially useful where many parallel control signals must be aggregated without requiring an FPGA.
Designers should use the Quartus II (legacy) or MAX+PLUS II toolchain to compile designs. A 1.0 mm-pitch FBGA requires careful PCB layout with microvia or via-in-pad technology; an external JTAG header (TCK, TMS, TDI, TDO, plus optional TRST) is required for ISP. Decouple each VCC and VCCIO pin with a 0.1 uF ceramic capacitor placed within 3 mm of the pin.

主な用途
EPM3512AFC256-7N の用途: 7 件s: Bus Interface Bridging and Address Decoding, Industrial Control and Factory Automation Glue Logic, Peripheral I/O Expansion for Embedded Microcontrollers, State Machine Controllers for Telecom and Datacom, Legacy Board Repair and Obsolescence Maintenance, Power Sequencing and System Reset Generation, Test and Measurement Equipment Front-End Logic.
Bus Interface Bridging and Address Decoding
The EPM3512AFC256-7N's 512 macrocells and 208 user I/Os are well suited for bridging between legacy and modern buses (ISA/PCI to local-bus glue, asynchronous SRAM to microcontroller, etc.) and for centralized address decoding in systems with many peripheral selects. Its deterministic 7.5 ns pin-to-pin propagation delay provides tight chip-select timing without timing closure iterations typical of FPGAs. Use it where the design is mostly combinational decode plus a few state machines, with 3.3V core and 2.5V/3.3V VCCIO banks allowing direct interface to mixed-voltage peripherals without external level shifters.
おすすめ
Industrial Control and Factory Automation Glue Logic
In industrial control cabinets, the EPM3512AFC256-7N aggregates many 24V-to-3.3V opto-isolated control signals and re-drives them to motor drivers, PLCs, and HMIs. The 208 I/Os allow direct parallel connection to dozens of isolated inputs/outputs without external muxing, while 5V-tolerant I/Os simplify interfacing to legacy 5V sensors. Deterministic timing enables reliable PLC scan-time behavior, and JTAG ISP lets field engineers reprogram the device without removing it from the panel via a JTAG header on the front door.
おすすめ
Peripheral I/O Expansion for Embedded Microcontrollers
The EPM3512AFC256-7N is ideal for expanding the limited I/O count of small microcontrollers (e.g., 80C51, MSP430, Cortex-M0) where designers need dozens of PWM outputs, GPIOs, or chip selects. Its 512 macrocells can host multiple UART/SPI/I2C controllers, custom timers, and watchdog logic, freeing the MCU to focus on application code. The 3.3V core matches modern MCUs, while 2.5V VCCIO banks allow connection to lower-voltage peripherals. JTAG ISP allows field firmware updates via a simple 4-wire header.
おすすめ
State Machine Controllers for Telecom and Datacom
Telecom and datacom line cards frequently require deterministic hardware state machines for protocol sequencing (e.g., HDLC framing, T1/E1 line-card glue, SERDES initialization). The EPM3512AFC256-7N's 7.5 ns propagation delay and 116.3 MHz fMAX are well matched to 8.192 MHz / 16.384 MHz backplane clocks, while the 512 macrocells can host multiple independent state machines in a single device. EEPROM-based non-volatile storage ensures instant-on behavior without external boot flash.
おすすめ
Legacy Board Repair and Obsolescence Maintenance
Many long-lifecycle industrial, medical, and aerospace boards originally built around the EPM3512AFC256-7N are still in field service. Because the part is obsolete (NRND), repair depots must keep an inventory of direct drop-in replacements. The EPM3512AFC256-10N, EPM3512AFC256-7, and other speed-grade variants in the same 256-ball FBGA package serve as repair substitutes, allowing a depot to consolidate orders across speed bins and reduce stock-out risk on a single MPN.
おすすめ
Power Sequencing and System Reset Generation
The EPM3512AFC256-7N can host complex multi-rail power-up/power-down sequencers and watchdog reset logic for systems with 8-16 voltage rails (CPU core, GPU, memory, I/O, PLLs). Its non-volatile EEPROM allows the sequencing order to be stored on-chip, eliminating external boot PROMs. The 208 I/Os are sufficient to drive dozens of enable and PG (power-good) signals directly, and the JTAG port lets field engineers re-tune sequencing without re-spinning firmware.
おすすめ
Test and Measurement Equipment Front-End Logic
Test instruments (oscilloscopes, logic analyzers, function generators) often require custom front-end routing and trigger logic that does not fit neatly into an FPGA's SRAM-based fabric. The EPM3512AFC256-7N's deterministic timing, EEPROM-based non-volatility, and 208 I/Os allow it to host a trigger matrix, channel multiplexer, and status indicator logic that boots instantly on power-up. Its 3.3V core and MultiVolt I/O support direct connection to modern ADC/DAC front ends.

設計ノート
The 256-ball FineLine BGA uses a 1.0 mm ball pitch, which demands either microvia (uVia) PCB technology or via-in-pad construction for reliable fan-out. Standard 0.1 mm laser-drilled microvias are recommended; tented or plugged microvias are required for fine-line BGA escape routing. Place at least one 0.1 uF X7R ceramic decoupling capacitor within 3 mm of every VCC and VCCIO pin, plus bulk 10 uF tantalum or polymer capacitors on each supply rail. A continuous ground plane on the layer immediately beneath the BGA is essential to control return paths and reduce simultaneous switching noise (SSN).
Do not confuse the 256-ball FBGA (1.0 mm pitch) with the larger 1.27 mm pitch BGA variants; land-pattern mistakes will cause shorts or opens. The VCCIO pins are banked, and each bank must be tied to either 3.3V or 2.5V; mixing voltages across banks without proper decoupling leads to CMOS input latch-up. The JTAG TRST pin (if present on the package variant) must be tied low through a 10 kohm resistor or driven by the programmer, otherwise the TAP controller may power up in an undefined state.
The FBGA-256 package has a theta-JA of approximately 18 C/W with a standard JEDEC test board, but in practice real-world designs with limited inner-plane copper can show 25 to 35 C/W. The MAX 3000A family's CMOS EEPROM process draws very low quiescent current (typically under 50 mA at 3.3V core), so thermal management is rarely a problem unless the design forces all 208 outputs to switch at the maximum 116.3 MHz simultaneously. Estimated: at 50% toggle rate and 50 pF load per pin, dynamic current adds ~10 mA, raising total to ~60 mA, well within the package's thermal envelope.
Place the JTAG header (TCK, TMS, TDI, TDO, plus optional TRST and VCC sense) on the board edge for in-system programming access without disassembling the chassis. Keep JTAG traces under 100 mm total length and series-terminate TCK with a 22 ohm resistor if the trace exceeds 50 mm. Quiescent VCCIO noise below 50 mVpp is required for reliable JTAG ISP; add a ferrite bead or pi-filter if the VCCIO rail is shared with high-di/dt loads. Reserve four general-purpose I/O pins for future ISP-triggered user-code update if field upgrades are anticipated.
コンプライアンス情報
RoHS compliance unknown because the part was originally released by Altera before RoHS documentation standardization. The 'N' suffix indicates Pb-free terminal finish, which suggests RoHS-compliant solder-joint compatibility, but a RoHS declaration document is not confirmed in the Verified Web Data.
