Use the A3P-MRAM development module when designing and developing your microcontroller applications. The A3P-MRAM FPGA module supports designing and developing of customized SL8051 (Silicon Laude) or Core8051 (Actel) microcontroller applications. As shown above, the board features an Actel ProASIC3 re-programmable FPGA, 512 kbytes of non-volatile Magneto-resistive Random Access Memory (MRAM), thirty-four undedicated user I/O's, with configurable voltage level between 1.5 and 3.3V, and an on-board USB-JTAG interface for programming the device as well as debugging the resulting microcontroller application.

Use the A3P-MRAM-BASE Board in conjunction with the  A3P-MRAM development module to provide a prototype area for circuit development.

The A3P-MRAM module is available in 4 configurations. With A3P1000 or A3P250 and with or without MRAM installed. Please refer to for specific part numbers.

• Up to 40 User I/Os
• 34 pins of User I/Os can be set to 3.3, 2.5 and 1.5V
• Integrated USB-JTAG Interface
• USB-powered with External 5 Volt Option
• Can supply up to 250 mA @5V to external logic
• Dimensions 2.4" x 1"

A3P-MRAM is a stand-alone multi-purpose controller module. It features a re-programmable FPGA, which can be programmed with the Silicon Laude SL8051 or Actel Core8051 microcontroller. The external 512 KB of MRAM allows for non-volatile storage of the controller data. The user program loaded on the module will always be available on power-up. The MRAM allows for very fast writing and read back of the contents; this provides an advantage over Flash memory which requires very long programming cycles.

• Quad LEDs providing simple status display.
• Two pushbutton momentary switches.

The microcontroller has direct control of four 8-bit bidirectional GPIO ports and single RS-232 port without transceiver for optional serial port logic which could be implemented on the FPGA. The built-in USB microcontroller provides a JTAG interface to the FPGA, allowing for device reprogramming and debugging of the loaded processor core. This functionality is compatible with Domain Technologies BoxViewIDE.
The A3P-MRAM is available with the re-programmable Actel ProASIC3 A3P1000 or A3P250 FPGA.

For logic projects not incorporating the microcontroller, there is available Real-time I/O to/from the PC over the USB,
