EPM3512AQI208-7 Ringkasan

The Altera (Intel) EPM3512AQI208-7 is a member of the MAX 3000A Complex Programmable Logic Device (CPLD) family, delivering 10,000 usable gates with 512 macro cells and a 116.3 MHz internal performance grade, housed in a 208-pin Plastic Quad Flat Pack (PQFP) package. It operates from a 3.3 V core supply and supports 2.5 V, 3.3 V, or 5.0 V I/O operation through separate VCCINT and VCCIO rails.

A CPLD (Complex Programmable Logic Device) is a non-volatile, flash- or EPROM-based programmable logic device that sits between simple PLDs and FPGAs in the programmable logic hierarchy: simple PLD < CPLD < FPGA. Compared with FPGAs, CPLDs offer deterministic timing (typically 5-10 ns pin-to-pin), instant-on non-volatile configuration, and very low standby power, which makes them well suited for glue logic, bus decoding, and power-sequencing tasks in larger systems.

Key features of the EPM3512AQI208-7 include 512 macro cells (arranged in 16 Logic Array Blocks of 32 cells each), 100% non-volatile in-system programmability compliant with the IEEE Std. 1532 ISP specification, 3.3 V core operation with multi-voltage I/O support, and a speed grade of -7 which delivers a tPD (pin-to-pin delay) of approximately 7.5 ns and an fCNT toggle rate around 116.3 MHz. The device integrates JTAG boundary-scan support and a 4-pin JTAG interface for ISP.

Architecturally, the EPM3512AQI208-7 uses an EPROM-based programmable interconnect matrix (PIA) and product-term macro cells - a classic MAX-style architecture that has shipped in hundreds of millions of units since the mid-1990s. Its non-volatile bit cells retain logic configuration without external boot memory, which simplifies board layout and BOM cost versus SRAM-based FPGAs.

Typical applications include industrial control glue logic, address decoding and bus interfacing for legacy microprocessors, power-supply sequencing in multi-rail systems, peripheral expansion in 8051/PIC-based designs, and prototyping interfaces for ASIC emulation. The PQFP-208 footprint also allows hand-soldering and socketed prototyping, which is rarely possible with modern fine-pitch BGA packages.

When designing with this device, ensure that both VCCINT (3.3 V) and VCCIO (2.5 V / 3.3 V / 5.0 V) rails are properly decoupled with 0.1 uF and 10 uF capacitors placed close to the pins. The MAX 3000A is mature and in NRND/EOL transition for many variants, so design for second-source availability within the same PQFP-208 footprint (such as the EPM3512AQC208-7 family).
