Pluggable Processor Module D2 (PPM D2)

PPM D2 is a pluggable processor module (PPM) for use with the CubeSat-compatible Motherboard Module (MBM). This is flight hardware (blue). By adding a PPM D2 to an MBM, the user creates a CubeSat-compatible Command & Data Handling (C&DH) module built around a Microchip dsPIC33FJ256GP710 16-bit low-power Digital Signal Controller (DSC) with built-in DSP instructions. PPM D2 has a dsPIC33FJ256GP710 with 256 KB internal Flash memory and 30,720 B internal RAM, and enables up to 20 MIPS operation via its 8 MHz external crystal. PPM D2 also has an on-board, external AT25DF641 64 Mbit SPI serial Flash memory chip.

Each unit includes a fully tested PPM D2 with a Microchip dsPIC33FJ256GP710 soldered in place. PPM D2 is part of the CubeSat Kit flight hardware line and plugs into a Motherboard Module (MBM); it is used on flight hardware to run fully debugged dsPIC33 software and to control fully debugged hardware on the CubeSat Kit. PPM D2 is electrically identical to PSPM D, so software developed on PSPM D will run identically on PPM D2 in a flight environment.

Compatibility: Motherboard Module (MBM), Development Board (DB), JFPC-PIC24, Microchip dsPIC33FJ256GP710. PPM D2 is compatible with the MBM (and DB) but not compatible with the newer MBM 2.

PPM D2 is included in: the CubeSat Kit /dsPIC33 (PSPM D + PPM D2) and the CubeSat Kit Upgrade to dsPIC33 (PSPM D + PPM D2). It carries Flight Hardware, Flight Qualified, and Space Proven classifications, indicating flight heritage.

Purchasing restrictions: prospective customers must purchase an entire CubeSat Kit first before purchasing additional PPM D2s a la carte; it is available only to customers who have already purchased a CubeSat Kit /dsPIC33, with proof of prior purchase required.
