NP108 module¶

This module is built around 18x Conexant/Mindspeed RL56CSMV/6 chips (data sheet see RL56CSMV_6.pdf). Each of the chips features its own MT48LC4M16A2 RAM chip. Internally, each of those chips contains an ARM core for management, and six Digital Data Pump dies.

Interfacing with the backplane is done via 3x Intel i960.
