Cortex-M3 at 50 MHz with 32 KB Flash
The Texas Instruments LM3S610-EGZ50-C2T is a Stellaris ARM Cortex-M3S 600 series microcontroller built around a 32-bit ARM Cortex-M3 core running at 50 MHz (cite:,). It carries 32 KB of on-chip Flash program memory and 8 KB of SRAM (cite:,), which is the memory budget for control-loop code, communication stacks, and data buffering in a single-chip design.
The peripheral set includes I²C, SPI, SSI, UART/USART, and legacy Microwire interfaces — enough for sensor fusion, serial displays, and fieldbus gateways in a single MCU (cite:). Two 10-bit ADC channels handle analog feedback from potentiometers, current shunts, or temperature sensors without an external converter (cite:). On-chip brown-out detect, POR, PWM, and a watchdog timer reduce the external supervisor IC count (cite:). The internal oscillator means the device can run without an external crystal for applications that tolerate the factory-calibrated accuracy (cite:).
Package, footprint, and supply posture
Tape & Reel packaging suits automated pick-and-place assembly (cite:).
