Product details

80 MHz Cortex-M3 with Ethernet and USB OTG

The LM3S9B96-IQC80-C0T is a Texas Instruments Stellaris ARM Cortex-M3 MCU from the 9000 series, built around a 32-bit single-core processor clocked at 80 MHz. The 100-LQFP package provides 65 GPIOs and a 16-channel 10-bit ADC for sensor acquisition.

256 KB Flash and 96 KB RAM — firmware budget check

The 256 KB Flash and 96 KB RAM are the memory envelope for this part. An Ethernet TCP/IP stack with a web server and a CANopen node can fit comfortably; a full GUI frame buffer or large data-logging buffer will push the RAM limit. The 96 KB is shared between code and data — factor in the stack and heap footprint early in the firmware partition.

Frequently asked questions
