EPM3512AQ208-10N Tóm tắt

The Intel / Altera EPM3512AQ208-10N is a member of the MAX 3000A Complex Programmable Logic Device (CPLD) family, delivering 512 macrocells, 172 user I/Os, and 10,000 usable gates in a 208-pin PQFP package with a -10 speed grade (10 ns pin-to-pin delay). It is fabricated on an advanced CMOS EEPROM process, operates from a 3.3 V core supply, and supports 2.5 V, 3.3 V, or 5.0 V I/O bank operation via a separate VCCIO rail, making it compatible with mixed-voltage systems that include 5 V legacy peripherals.

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.
