About the Module
CHAPTER 1
The ConnectCore 9P 9215 family of modules delivers powerful network-enabled
core processor solutions with up to 16 MB of NOR flash, up to 32 MB SDRAM, a rich
set of integrated peripherals, and superior design flexibility.
At the heart of the modules is a Digi 32-bit ARM9-based NS9215 processor running at
150 MHz. Key features include 10/100 Mbit Ethernet, two on-chip Flexible Interface
Modules (FIMs), 256-bit AES accelerator, power management modes with dynamic
clock scaling, and a rich set of on-chip peripherals. Based on Digi 802.11 baseband
technology, the ConnectCore Wi-9P 9215 also provides an additional 802.11a/b/g
interface with enterprise-grade WPA2/802.11i support.
The unique FIMs on the NS9215 processor are two independent 300 MHz DRPIC165X
processor cores that allow customers to dynamically select application-specific
interfaces in software. The growing list of supported interfaces includes UART,
SD/SDIO, CAN bus, USB-device low-speed, 1-Wire®, USB device low-speed, parallel
bus interface, and others.
Utilizing the Digi NET+ARM processor and secure 802.11a/b/g WLAN technology, the
family of ConnectCore 9P 9215 modules offers the industry’s only network-enabled
core module with true long-term product availability to meet the extended life
cycle requirements of embedded product designs.
For further information about the NS9215, see the NS9215 Hardware Reference.
