EPM3512AQC208-7N/I20 - 512-Macrocell MAX 3000A CPLD, 208-PQFP | Altera
MPN: EPM3512AQC208-7N/I20 ✗ Cuối đờiEPM3512AQC208-7N/I20 Tóm tắt
A CPLD (Complex Programmable Logic Device) is a non-volatile, instantly-on programmable logic device that sits between simple PAL/GAL devices and higher-density FPGAs in the programmable logic hierarchy: PAL/GAL -> CPLD -> FPGA -> SoC FPGA. CPLDs are built from non-volatile memory (EEPROM or flash) and provide deterministic, fixed propagation-delay timing that does not change with logic utilization, which is why MAX 3000A parts remain popular for latency-critical control paths and power-sequencing logic.
Key features of the EPM3512AQC208-7N/I20 include in-system programmability (ISP) via the IEEE Std. 1149.1 JTAG interface, IEEE Std. 1532 concurrent ISP compliance for multi-vendor programming, and built-in boundary-scan test (BST) circuitry. The device operates from a single 3.3 V supply (3.0 V to 3.6 V) and is offered in the commercial 0 C to 70 C temperature grade. MultiVolt I/O allows interfacing with 1.8 V, 2.5 V, and 3.3 V logic without external level shifters.
Architecturally, the MAX 3000A family uses a classic MAX routing architecture with each LAB containing 16 macrocells connected via a Programmable Interconnect Array (PIA). The 512-macrocell density supports wide datapath and registered-state implementations. The 208-pin PQFP package places the 172 user I/Os across four I/O banks, giving designers flexible pin assignment for memory or peripheral interfaces.
Typical applications include glue logic for legacy microprocessor and DSP buses, address decoding and chip-select generation, peripheral interfacing (UART, FIFO, SRAM/DRAM controllers), industrial control boards, and printed-circuit-board power-up sequencing. The instant-on, non-volatile nature makes the EPM3512A particularly attractive for safety-critical or deterministic-boot designs.
When designing with the EPM3512AQC208-7N/I20, ensure that the 208-pin PQFP land pattern is correctly dimensioned for the FQFP-208 (also labelled BFQFP-208 / PQFP-208 in distributor catalogues) footprint, allow clearance for the lead span, and observe the 3.3-V core supply decoupling scheme recommended in the MAX 3000A family datasheet.

Ứng dụng tiêu biểu
EPM3512AQC208-7N/I20 phù hợp cho 6 Áp dụngs: Microprocessor / DSP Bus Glue Logic, Address Decoding and Chip-Select Generation, Industrial Control Board Logic, Power-Sequencing and Reset Distribution, Peripheral Interface Bridging, Legacy Telecom Backplane Glue Logic.
Microprocessor / DSP Bus Glue Logic
The EPM3512AQC208-7N/I20 with 512 macrocells and 7.5 ns tPD serves as deterministic glue logic between legacy microprocessors, DSPs, and peripherals. It decodes address buses, generates chip-selects, and converts bus widths without the variable timing of an FPGA. Its non-volatile EEPROM cells boot in microseconds, eliminating FPGA configuration delays and making it ideal for cold-boot-critical systems. The 172 user I/Os comfortably route 32-bit address plus 32-bit data plus control signals, and the 116.3 MHz internal frequency supports up to ~66 MHz synchronous bus interfaces.
Được đề xuất
Address Decoding and Chip-Select Generation
With 32 LABs and 512 macrocells, the EPM3512AQC208-7N/I20 can implement large address-decoding trees for memory maps spanning multiple banks of SRAM, DRAM, Flash, and peripherals. Each macrocell provides a programmable product term, register, and tri-state control, enabling registered chip-select outputs that meet 7.5 ns setup time for modern microprocessors. The deterministic tPD simplifies worst-case timing closure, and the 172 I/Os comfortably address 20+ peripheral chip-selects with margin for future expansion.
Được đề xuất
Industrial Control Board Logic
The 0 C to 70 C commercial temperature range and robust CMOS EEPROM technology of the EPM3512AQC208-7N/I20 suit it for industrial control boards requiring deterministic I/O timing. The device consolidates dozens of 74-series TTL/CMOS glue parts into a single IC, reducing PCB area, BOM count, and supply-chain risk on long-lifecycle industrial products. The JTAG-supported ISP allows in-field firmware updates without removing the board from the chassis, and the 208-pin PQFP package is friendly to through-hole-like rework on legacy manufacturing lines.
Được đề xuất
Power-Sequencing and Reset Distribution
The instant-on, non-volatile nature of the EPM3512AQC208-7N/I20 makes it well suited to power-rail sequencing in multi-voltage systems. It can monitor voltage-rail good signals from supervisors and assert enables to DC-DC converters and LDOs in a defined order with microsecond timing precision, eliminating the timing variability of discrete RC delay networks. Its 7.5 ns propagation delay supports tight sequencing of rails for processors requiring strict power-on order, and the 172 user I/Os comfortably handle 10+ independent power domains with margin.
Được đề xuất
Peripheral Interface Bridging
The EPM3512AQC208-7N/I20 bridges between incompatible peripheral interfaces - for example, converting a parallel FIFO bus to an SPI-controlled GPIO expander, or translating an Intel-style bus to a Motorola-style bus for legacy peripherals. Its 116.3 MHz internal frequency supports up to 50 MHz state-machine operation, sufficient for UART, SPI, I2C, and parallel-port bridging at standard baud rates. MultiVolt I/O (1.8/2.5/3.3 V) lets it sit directly between modern SoCs and 5 V-tolerant legacy peripherals.
Được đề xuất
Legacy Telecom Backplane Glue Logic
Telecom backplanes built around ATCA / CompactPCI architectures still rely on MAX 3000A CPLDs for hot-swap control, I2C management bus isolation, and interrupt routing. The EPM3512AQC208-7N/I20's 172 I/Os comfortably aggregate multiple board-management signals, and its 3.3 V core with 5 V-tolerant I/O is ideal for mixed-voltage backplane environments. The JTAG-supported ISP enables in-system firmware updates during board bring-up without removing line cards from service.

Ghi chú thiết kế
Decouple each VCCINT pin with a 0.1 uF ceramic capacitor placed within 5 mm of the pin, plus a single 10 uF bulk capacitor near the supply entry. Place 0.1 uF caps on every VCCIO bank supply as well. The 512-macrocell core draws up to ~300 mA during programming pulses, so the 3.3 V regulator must supply at least 500 mA peak with <100 mV transient excursion.
Estimated: at 116.3 MHz toggling all 172 I/Os with 10 pF loads, dynamic core power is ~0.7 W. Combined with ~50 mW static power, total dissipation is ~0.75 W; on a 4-layer PCB with PQFP-208 thermal pad of ~32 C/W theta_JA, junction rises ~24 C above ambient. No heatsink required, but provide continuous ground plane under the package for best thermal performance.
Route JTAG signals TDI, TMS, TCK, TDO as a 4-wire bus with 10 kohm pull-ups on TDI/TMS/TCK to VCCIO. Keep the JTAG chain under 150 mm and avoid stubs. The 208-pin PQFP has a 0.5 mm lead pitch and 30.6 mm body width; use 0.25 mm-wide traces with 0.20 mm spaces and micro-vias on inner escape layers to fan out cleanly.
Do not connect 5 V signals directly to I/O pins when VCCIO is 3.3 V unless the input is verified 5 V-tolerant (MAX 3000A inputs are 5 V-tolerant with 3.3 V VCCIO). Never apply 5 V to VCCINT - the absolute maximum is 4.0 V. Always include the JTAG IDCODE check in your BSDL file before in-system programming; the factory default IDCODE for the EPM3512A is 0x0120A0DD.
Thông tin tuân thủ
Pb-free lead finish (N suffix) indicates SnPb-free plating, but RoHS compliance was not explicitly stated in the verified web data; AEC-Q100 not applicable because the device is a commercial-grade (0-70 C) programmable logic IC, not an automotive-grade IC.
