EPM3512AQ208-10N 概要
A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines multiple PAL-like logic blocks with a central interconnect matrix. CPLDs sit in the programmable-logic hierarchy below FPGAs and above discrete glue logic (74-series), offering deterministic timing, instant-on behavior from on-chip EEPROM, and predictable pin-to-pin delays as fast as 4.5 ns in the MAX 3000A family. They are typically used for I/O expansion, bus bridging, state-machine control, and address decoding where deterministic timing and battery-free configuration retention are required.
The EPM3512A delivers up to 10,000 usable gates and counter speeds reaching 227.3 MHz. It features in-system programmability (ISP) compliant with IEEE Std. 1532, which allows concurrent programming across multiple vendors. The device includes four JTAG I/O pins (TDI, TDO, TMS, TCK) for boundary-scan test and programming, plus a dedicated INPUT pin for fast input paths and a global CLEAR pin for asynchronous reset.
Architecturally, the device is built from Logic Array Blocks (LABs) interconnected by a Programmable Interconnect Array (PIA). Each macrocell contains a programmable AND/OR/registered array, a product-term selector, and a flip-flop with independent programmable clock, clear, and preset controls. The 208-pin PQFP package provides 172 usable I/O pins with 5-V tolerant inputs in 3.3-V mode, suitable for industrial control, glue-logic replacement, and bus-interface bridging.
Typical applications include PCI bus interface glue logic, telecommunications backplane control, industrial PLC I/O expansion, JTAG-based test infrastructure, and legacy 5V-to-3.3V voltage translation. The non-volatile EEPROM configuration means designs boot instantly without an external configuration memory, simplifying board layout and reducing BOM cost.
When designing with this device, observe the VCCINT/VCCIO dual-suprail requirement and place 0.1 uF decoupling capacitors near each supply pin. For high-speed designs, route JTAG signals with characteristic impedance control and avoid stub branches longer than one-eighth of the signal rise time.
This page synthesizes distributor pricing, IEEE 1532 programming notes, and pin-compatible MAX 3000A alternatives not consolidated in the manufacturer datasheet, helping engineers select a drop-in equivalent quickly.

主な用途
EPM3512AQ208-10N の用途: 6 件s: PCI Bus Interface Glue Logic, Industrial PLC I/O Expansion, Telecommunications Backplane Control, JTAG-Based Test Infrastructure, Legacy 5V to 3.3V Voltage Translation, Address Decoding and Chip Select Generation.
PCI Bus Interface Glue Logic
The EPM3512AQ208-10N is well-suited for PCI bus interface glue logic in industrial and embedded systems because its 4.5 ns pin-to-pin delay and 227.3 MHz counter speed meet PCI timing requirements for address decoding and command signal generation. Its 172 I/Os comfortably handle 32-bit address plus 32-bit data plus control signals with margin for chip selects and interrupts. The IEEE 1532 ISP simplifies firmware updates on production boards. Compared to discrete 74-series logic, a single CPLD replaces dozens of packages, reducing PCB area, BOM count, and propagation skew between parallel paths.
おすすめ
Industrial PLC I/O Expansion
In industrial PLC and process-control designs, the EPM3512AQ208-10N provides deterministic glue logic for I/O expansion modules, encoder interfacing, and isolated digital I/O aggregation. The 3.3 V core with 5 V-tolerant I/Os simplifies interface to legacy 24 V field-translated logic, and the industrial -40 C to +85 C operating range covers most factory environments. The 10,000 usable gates accommodate up to several dozen state machines and address decoders, while instant-on EEPROM configuration eliminates external boot memory - critical for PLCs that must be operational within milliseconds of power-up.
おすすめ
Telecommunications Backplane Control
The EPM3512AQ208-10N excels at telecommunications backplane control applications such as T1/E1 framer glue, line-card interface logic, and clock-distribution steering. Its high 172 I/O count supports multi-port serial interfaces and bus isolation between line cards and switch fabric. The 227.3 MHz internal counter speed handles high-rate bit-stuffing and clock-recovery state machines, while the deterministic tPD ensures consistent framing latency. ISP via JTAG allows field firmware updates without removing line cards from service.
おすすめ
JTAG-Based Test Infrastructure
For JTAG-based boundary-scan test and in-system programming infrastructure, the EPM3512AQ208-10N acts as a JTAG chain extender, TAP controller aggregator, or BSDL-driven test access port. Its 4 dedicated JTAG pins and 172 user I/Os allow it to fan out test access to multiple downstream devices while supporting boundary-scan tests on its own I/O pins. The IEEE 1532 compliance ensures interoperability with other vendors' JTAG-capable parts, simplifying mixed-vendor PCB test development.
おすすめ
Legacy 5V to 3.3V Voltage Translation
The EPM3512AQ208-10N functions as a level-translation bridge between legacy 5 V peripherals and 3.3 V processors, using its 5 V-tolerant inputs and configurable VCCIO banks. A single CPLD can replace multiple bus-switch ICs and 74LVC245 transceivers, with the added benefit of programmable direction control and bus-hold behavior. This simplifies board design when migrating from 5 V MCUs to 3.3 V ARM processors while preserving existing 5 V peripherals on the same PCB.
おすすめ
Address Decoding and Chip Select Generation
The EPM3512AQ208-10N is widely used for address decoding and chip-select generation in microprocessor systems where multiple memory and peripheral devices share a common bus. Its 172 I/Os allow dozens of chip-select outputs with sub-10 ns propagation delay, ensuring zero wait-state operation with fast processors. The programmable AND/OR array with optional output registers handles complex address maps and timing requirements that would otherwise require multiple 74-series decoders, while EEPROM configuration preserves decoding logic through power cycles.

設計ノート
The EPM3512AQ208-10N requires two separate supply rails: VCCINT (3.3 V) for internal logic and input buffers, and VCCIO (2.5 V, 3.3 V, or 5.0 V) for I/O output drivers. Each VCCINT/VCCIO pin must have a 0.1 uF decoupling capacitor placed within 100 mils of the pin, with additional 1 uF to 10 uF bulk capacitors on each supply rail. Mixed-voltage designs can configure VCCIO1-VCCIO4 independently, but VCCINT must remain at 3.3 V +/- 0.3 V. Power sequencing is not required; either rail may come up first without damaging the device.
For the 208-pin PQFP package, route JTAG signals (TDI, TDO, TMS, TCK) with characteristic impedance of 50 ohms and keep traces shorter than 4 inches to avoid signal integrity issues at programming time. Place a 4.7 kohm pull-up resistor on TMS and TDI per IEEE 1532 recommendations to keep the JTAG TAP controller in a known state at power-up. Ensure the TCK trace has a clean ground reference and avoid routing JTAG signals near switching power or high-frequency clock traces to prevent programming failures.
Estimated: At -10 speed grade with 172 active outputs switching at 33 MHz CMOS loads, ICC (core current) may reach 150 mA and I/O current may add 10-50 mA per bank. Verify thermal dissipation by calculating total package dissipation and ensuring junction temperature stays below 150 C. Also note that all VCCIO banks must be powered even if unused - floating VCCIO pins cause unpredictable I/O behavior. Always program the device before connecting outputs to live buses to avoid contention during initial power-up.
