LUMINARY MICRO LM3S9B90 User Manual

Stellaris® LM3S9B90
Ethernet+USB-OTG Evaluation Kit

The Stellaris® LM3S9B90 Ethernet+USB-OTG
Evaluation Kit provides a low-cost evaluation platform
for the LM3S9B90 ARM® Cortex™-M3-based
microcontroller. The kit includes two boards: the
EK-LM3S9B90 evaluation board, and the BD-ICDI
In-Circuit Debug Interface board.The evaluation board
design highlights the LM3S9B90 microcontroller’s
10/100 Mbit Ethernet port, full-speed USB-OTG port,
In-Circuit Debug Interface (ICDI) board, and easy
connection to the GPIO ports.

Features

The evaluation board uses the LM3S9B90
microcontroller which features a Hibernation module to
efficiently power down the device to a low-power state
during extended periods of inactivity.The LM3S9B90
microcontroller also features an external 16 MHz
crystal that provides the main oscillator clock which
can directly drive the ARM core clock or an internal
PLL to increase the core clock up to 80 MHz. A
25 MHz crystal is used for the Ethernet clock and a

4.194304 MHz crystal is used for the real-time clock.
The LM3S9B90 microcontroller also has an internal
LDO voltage regulator that supplies power for internal
use.
