About the Module
CHAPTER 1
The NS9210 Processor Module is part of the ConnectCore embedded core
processor module family. Built on leading Digi technology, the network-enabled
ConnectCore 9P family provides a modular and scalable core processor solution that
significantly minimizes hardware and software design risk. This module combines
superior performance and a complete set of integrated peripherals and component
connectivity options in a compact and versatile form factor.
The NS9210 Processor Module is built around the NS9215 processor with a powerful
ARM926EJ-S core. For further information about the NS9215, see the NS9215
Hardware Reference available through your Digi JumpStart Kit. The embedded
module offers 8MB SDRAM and can support a maximum of 64MB SDRAM. The module
has also 4MB NOR flash and can support up to a maximum of 16MB NOR flash, a
single high speed serial peripheral interface (SPI) module, an I2C interface, UARTs,
programmable flexible interface modules (FIMs), ADC, 16-bit data/17-bit address
bus (buffered), and 64 shared GPIO signals for application-specific usage.
