The 96 KB on-chip flash (96K x 8) and 32 KB SRAM (32K x 8) fit a moderate application stack: a FreeRTOS kernel plus a CANopen stack leaves roughly 40 KB flash and 12 KB RAM for the application layer, so budget tightly if you are adding a TCP/IP stack or large data buffers. ## Peripheral set and connectivity — what hooks into the bus The connectivity block includes CAN, I²C, IrDA, Microwire, SPI, SSI, and UART/USART — this covers fieldbus bridging (CAN to UART gateway), sensor aggregation over I²C, and SPI flash or display interfaces. Three 10-bit ADC channels handle basic analog sensing (potentiometer feedback, thermistor voltage), but the 10-bit resolution limits precision measurement — a 0-10 V sensor gives 9.8 mV per step. On-chip peripherals include brown-out detect, POR, PWM, and watchdog timer — these reduce the external supervisor IC count and simplify the power-on sequence. The internal oscillator eliminates the external crystal for many applications, though the accuracy is adequate for UART baud rates, not for CAN bit timing at high bus speeds. ## Package and board integration — BGA layout notes The 108-BGA package (10x10 mm) with 0.80 mm ball pitch demands a 4-layer PCB for fan-out — two-layer boards will struggle to route the inner balls. ## Lifecycle reality — NRND and what that means for your BOM Texas Instruments lists the LM3S2432-IBZ50-A2 as NRND (Not Recommended for New Designs). This means the part is still available for existing production but is not intended for new projects.","metaTitle":"TI LM3S2432-IBZ50-A2 ARM Cortex-M3 MCU, 50 MHz, 96 KB Flash","metaDescription":"Texas Instruments LM3S2432-IBZ50-A2 Stellaris ARM Cortex-M3 MCU, 50 MHz, 96 KB flash, 32 KB RAM, 108-BGA.
