EPM3032ATC44-10AA Visão geral

The Intel (formerly Altera) EPM3032ATC44-10AA is a 32-macrocell, 34-I/O Complex Programmable Logic Device (CPLD) from the MAX 3000A family, offering 600 usable gates, 10 ns pin-to-pin propagation delay, and 3.3 V in-system programmability through the IEEE Std. 1149.1 JTAG interface in a 44-pin TQFP package. The -10 speed grade provides a maximum propagation delay of 10 ns and counter frequencies up to 227.3 MHz, while the 'A' suffix denotes the 3.3 V core supply and the 'C' denotes the commercial 0C to +70C operating temperature range.

A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines multiple PAL/GAL-like logic blocks with a centralized interconnect matrix. CPLDs sit in the programmable logic hierarchy between simple SPLDs (PAL/GAL) and large FPGAs; they offer instant-on (zero-configuration) behavior, deterministic timing, and high-drive I/O. The MAX 3000A family uses EEPROM configuration cells, eliminating the need for external boot memory and supporting multi-vendor ISP per IEEE Std. 1532.

Key features include 32 macrocells across 2 logic array blocks (LABs), 34 user I/O pins, 3.3 V core supply (VCCINT) with selectable 2.5 V/3.3 V/5.0 V I/O supply (VCCIO), an IEEE Std. 1149.1 JTAG boundary-scan test interface, and built-in ISP compliance per IEEE Std. 1532. The MAX architecture delivers predictable timing because routing paths through the programmable interconnect array (PIA) have fixed delays that do not depend on user logic placement.

The MAX 3000A architecture employs a classic AND-OR-XOR macrocell with a product-term allocator, shared logic expanders, and a per-macrocell flip-flop with programmable clear, preset, and clock options. The EEPROM-based configuration is one-time programmable per logic cell, with ISP re-programmability through JTAG. The I/O structure is split: VCCINT powers the core and input buffers, VCCIO powers the output drivers, allowing mixed-voltage interfacing without external level shifters. The 44-pin TQFP package provides a compact 10 mm x 10 mm footprint for surface-mount designs.

Typical applications include glue-logic integration in industrial controllers, address decoding and bus interfacing in embedded systems, state-machine replacement in motor control, I/O expansion for legacy microcontrollers, and JTAG-configured bus bridges. The instant-on behavior is valuable in safety-critical and deterministic-latency paths where FPGA configuration time is unacceptable.

When designing with this part, observe the dual-supply requirement: VCCINT must be 3.3 V, while VCCIO can be tied to 2.5 V, 3.3 V, or 5.0 V depending on the interface voltage of the connected devices. Decouple both rails locally with 0.1 F and 10 F capacitors.
