Product Overview

EKI-LM3S9B90 is a stellaris LM3S9B90 Ethernet plus USB to OTG evaluation kit provides a low cost IAR systems embedded workbench evaluation platform for the LM3S9B90 ARM Cortex-M3 based microcontroller. The evaluation board design highlights the LM3S9B90's 10/10Mbit Ethernet port, full speed USB to OTG port, In Circuit Debug interface (ICDI) board and easy connection to the GPIO ports. LM3S9B90 MCU 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 16MHz 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 80MHz. A 25MHz crystal is used for the Ethernet clock and a 4.194304MHz crystal is used for the real time clock, internal LDO voltage regulator.
