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 Digi 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 ConnectCore 3G 9P 915 module allows you to instantly add intelligent cellular
communication to your products.
Built on leading Qualcomm Gobi 2000 technology, the module delivers a pre-
certified embedded cellular connectivity solution without the traditional
carrier/network limitations. Selecting cellular network technology and carriers is
now a matter of software configuration and service provisioning, any time.
The unique FIMs on the Digi 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.
