EPM3512AQC208-7 概要
A Complex Programmable Logic Device (CPLD) is a non-volatile programmable logic device that combines multiple PAL-like logic blocks on a single chip, providing predictable timing, instant-on behavior, and high I/O count for glue-logic, bus-interface, and state-controller applications. CPLDs sit alongside FPGAs in the programmable logic hierarchy: FPGAs offer higher logic density and register count, while CPLDs excel at deterministic timing, lower power, and instant boot from on-chip EEPROM. The MAX 3000A family targets cost-sensitive industrial, communication, and consumer designs that need fast, deterministic logic integration.
The EPM3512AQC208-7 integrates in-system programmability (ISP) compliant with the IEEE Std. 1532 specification, allowing concurrent ISP across multiple PLD vendors and reconfiguration without removing the device from the board. The MultiVolt I/O pins interface directly with 5.0 V, 3.3 V, and 2.5 V logic, eliminating external level shifters when bridging legacy and modern buses. Built on a 0.30 um CMOS EEPROM process with a MAX architecture, the device delivers high logic density with predictable interconnect delays that are independent of routing patterns, simplifying static-timing closure.
Typical applications include bus-interface bridging, address decoding and glue logic for microprocessor systems, state-machine controllers, I/O expansion, and power-up sequencing for FPGAs or processors requiring controlled reset behavior. Designers often pair the EPM3512AQC208-7 with an external configuration PROM or use it standalone for deterministic control logic. Its instant-on EEPROM architecture boots the configured logic within microseconds, which is critical for safety-critical and deterministic system bring-up.
When designing with the EPM3512AQC208-7, observe the 208-PQFP thermal envelope and provide a sufficient ground/power plane on inner PCB layers to keep junction temperature below 125 C. Decouple each VCCINT and VCCIO pin with a 0.1 uF ceramic capacitor placed within 100 mils of the pin, and use the Quartus II or MAX+PLUS II software toolchain for fitting, simulation, and JTAG-based ISP.

主な用途
EPM3512AQC208-7 の用途: 6 件s: Microprocessor Bus Interface Bridging, FPGA Configuration and Power Sequencing Controller, State Machine and Control Logic, Address Decoding and Memory Interfacing, I/O Expansion and GPIO Multiplexing, Legacy System Maintenance and Drop-In Replacement.
Microprocessor Bus Interface Bridging
The EPM3512AQC208-7's 172 user I/Os and 7.5 ns tPD make it an ideal bridge between microprocessors, DSPs, and peripherals operating at different bus widths or voltages. Its MultiVolt I/O directly interfaces 5.0 V legacy peripherals with 3.3 V modern cores without external level shifters, reducing BOM cost and board area. With 512 macrocells and deterministic timing, it can decode full 24-bit address spaces in a single pass, providing chip-select generation, wait-state insertion, and interrupt prioritization for systems requiring fast, predictable glue logic.
おすすめ
FPGA Configuration and Power Sequencing Controller
FPGAs require strict multi-rail power-up and reset sequencing to prevent inrush damage and configuration errors. The EPM3512AQC208-7's instant-on EEPROM architecture boots in microseconds - far faster than FPGAs that need external configuration time - allowing it to drive enable lines, monitor PGOOD flags, and release FPGA reset only after all rails stabilize. Its 172 I/Os can manage multiple FPGAs, voltage regulators, and monitoring rails simultaneously, while the deterministic 7.5 ns tPD guarantees precise timing margins for sequenced power systems in industrial and telecom hardware.
おすすめ
State Machine and Control Logic
Industrial controllers, motor drives, and instrumentation require deterministic state machines with guaranteed response times. The EPM3512AQC208-7's CPLD architecture provides predictable, routing-independent 7.5 ns pin-to-pin delays that simplify static-timing analysis - unlike FPGAs whose interconnect delays vary with placement. With 512 macrocells and 116.3 MHz counter frequency, designers can implement multi-state FSMs, PWM generators, quadrature decoders, and protocol controllers in a single device, while the instant-on EEPROM eliminates boot-time variability in safety-critical control loops.
おすすめ
Address Decoding and Memory Interfacing
Memory subsystems require precise address decoding with sub-nanosecond setup times to avoid bus contention. The EPM3512AQC208-7's 7.5 ns tPD and 172 I/Os support full 32-bit address decoding with multiple chip-select outputs that enable memory banks, ROMs, and peripherals in a single cycle. Its MultiVolt I/O interfaces directly with SRAM, DRAM, and Flash memories operating at 5 V or 3.3 V without glue logic. The deterministic timing makes it a preferred choice for legacy CPU boards and 8/16/32-bit embedded systems requiring reliable address decoding.
おすすめ
I/O Expansion and GPIO Multiplexing
Embedded systems frequently need more I/Os than the host microcontroller provides. The EPM3512AQC208-7 with 172 user I/Os can multiplex keypad rows/columns, LCD segment drivers, LED displays, and parallel peripherals through a serial SPI or I2C interface from the host. Its 3.3 V core with 5 V-tolerant I/O directly drives both modern and legacy peripherals, while the in-system programmability via JTAG allows field firmware updates without desoldering. This makes it ideal for industrial HMIs, point-of-sale terminals, and instrumentation front panels.
おすすめ
Legacy System Maintenance and Drop-In Replacement
Many industrial, military, and aerospace systems designed in the late 1990s and early 2000s use the EPM3512AQC208-7 and now face EOL pressure on legacy components. The same -7 part with original Altera die remains available through distribution channels, providing an authentic drop-in replacement that preserves qualification, certification, and form-fit-function. Designers can also substitute speed-grade variants (-10, -3) within the same 208-PQFP package if stock of the -7 grade is constrained. This makes the EPM3512AQC208-7 family an essential part for sustaining legacy equipment.

設計ノート
Estimated: The EPM3512AQC208-7 draws approximately 100-300 mA at 3.3 V VCCINT depending on activity factor, plus I/O bank current at VCCIO. Decouple every VCCINT and VCCIO pin with a 0.1 uF ceramic capacitor placed within 100 mils of the pin; add a bulk 10 uF tantalum or ceramic near the device. Place VCCIO decoupling per bank because each bank can run at a different MultiVolt level. Use separate analog and digital ground planes joined at a single point under the CPLD.
The 208-PQFP has a theta_JA of approximately 35 C/W. At maximum commercial ambient (70 C) and typical 1 W dissipation, junction temperature rises 35 C to about 105 C - within the 125 C limit but with limited headroom. Provide thermal vias under the exposed die pad (PQFP has no exposed pad; rely on copper pour and inner-layer ground planes for heat spreading). Avoid placing the CPLD near high-power devices; in enclosed industrial housings, derate to 60 C ambient.
Route JTAG signals (TCK, TMS, TDI, TDO) with 4-8 mil traces and keep them under 2 inches; place a 10 kohm pull-up on TCK, TMS, TDI per IEEE 1532. The 208-PQFP has fine-pitch gull-wing leads at 0.5 mm pitch - use 4-layer PCB with 4-mil space/4-mil trace design rules for escape routing. Keep high-speed output traces short and series-terminate if driving more than 2 inches.
Do not confuse the 208-PQFP with the 256-FBGA (EPM3512AFI256-7) - they are NOT drop-in compatible despite sharing the 3512 die. The PQFP uses peripheral gull-wing leads while the FBGA uses a ball grid; pin functions and I/O bank assignments differ. Also, the EPM3512AQC208-7 vs EPM3512AQC208-7N differs only in lead finish (Pb vs Pb-free) - both are electrically identical. Use Quartus II 13.0 or earlier for design compilation; newer Quartus versions dropped MAX 3000A support.
When interfacing 5 V peripherals with the EPM3512AQC208-7, set the relevant VCCIO bank to 3.3 V (not 5 V) - the I/O pins are 5 V tolerant when VCCIO = 3.3 V per MultiVolt spec. Driving 5 V signals into a VCCIO=2.5 V bank exceeds absolute maximum ratings. For clock inputs, keep rise/fall times below 200 ns and avoid ringing by source-terminating fast edges with a 33 ohm series resistor at the driver.

RoHS compliance depends on suffix: the -7N suffix is explicitly Pb-free per FindIC data; the -7 suffix may be SnPb or Pb-free depending on date code. AEC-Q100 not qualified - commercial grade only (0-70 C). IEEE Std. 1532 ISP compliant.
