The PCM2 has two configurations: each of them is described in detail below.

The core of both the configurations is using the TMS320F2808GGMA which is a single chip DSP. This DSP is designed to implement servo amplifiers, outer analog and power designs.

The DSP contains 128KB flash, 18KBSram, 16 analog inputs 12 bit each. The outer IO capabilities support up to: 2 quad inputs, 8 PWM 2 SCI, 2CAN bus controllers and 4 SPI.

A programmable logic device (Altera) device expands the total IO lines of the DSP via SPI interface between the ALTERA device and the DSP.
