A3PE1500-1PQG208I - ProASIC3E FPGA 1.5M Gates | Microchip
The Microchip Technology A3PE1500-1PQG208I is a ProASIC3E flash-based Field Programmable Gate Array (FPGA) with 1.5 million system gates, 147 user I/Os, and 276,480 bits of true dual-port SRAM, housed in a 208-pin PQFP (FQFP) package. It operates from a 1.5V core supply (1.425V to 1.575V) and supports system performance up to 231 MHz (typical) in the -1 speed grade. This industrial-temperature (-40°C to 100°C junction) device is part of Microchip's low-cost, single-chip, reprogrammable FPGA family.
An FPGA (Field Programmable Gate Array) is an integrated circuit that can be configured by the customer after manufacturing to implement arbitrary digital logic functions. FPGAs belong to the programmable logic device (PLD) hierarchy, which sits above CPLDs and below ASICs in flexibility and cost. The ProASIC3E family uses a flash-based configuration cell, making it non-volatile, instant-on (Level 0 support), and single-chip—no external boot memory is required. This distinguishes it from SRAM-based FPGAs that need configuration from an external flash or EEPROM at power-up.
Key features include 1.5M system gates, 38,400 VersaTiles (each configurable as a 3-input LUT or D-flip-flop/latch with enable), 276,480 bits of true dual-port SRAM, and 147 user I/Os. The flash-based 130-nm, 7-layer metal (6 copper) CMOS process provides instant-on capability, design security, and low power consumption. The device supports multiple I/O standards, including LVCMOS, LVTTL, PCI, and LVDS, with programmable slew rate and drive strength. It also includes on-chip PLLs for clock management and a JTAG interface for programming and boundary-scan testing.
Architecturally, the ProASIC3E core tile (VersaTile) can be used as either a three-input lookup table (LUT) equivalent or as a D-flip-flop/latch with enable, allowing efficient use of the FPGA fabric. The flash-based configuration is reprogrammable, supporting in-system programming (ISP) via JTAG. The device is available in a 208-pin PQFP (FQFP) package with 0.5mm pitch, measuring 28mm x 28mm with 3.4mm height, and is lead-free (RoHS compliant). The -1 speed grade offers a maximum system performance of 231 MHz, while the industrial temperature grade ensures operation from -40°C to 100°C junction.
Typical applications include industrial control, communications/networking, computing, avionics, and consumer electronics where low cost, instant-on, and security are critical. The A3PE1500-1PQG208I is well-suited for ASIC replacement, glue logic, and medium-density digital designs. Its non-volatile configuration eliminates the need for external configuration memory, reducing BOM cost and board space.
When designing with this device, ensure adequate decoupling on the 1.5V core supply and 3.3V I/O supply. The flash-based architecture requires no configuration loading time, but proper power sequencing is recommended. For high-speed I/O, follow the PCB layout guidelines in the ProASIC3E datasheet to minimize signal integrity issues.
