It carries an integrated Ethernet MAC and PHY alongside I²C, SPI, SSI, UART, IrDA, Microwire, and QEI peripherals — enough serial connectivity to serve as the communications hub in an industrial controller or a building-automation gateway. The 100-LQFP package (14x14 mm) keeps the board footprint compact while still routing 43 GPIOs and a 3-channel 10-bit ADC. The Flash is enough for a moderate application with an Ethernet stack and a few protocol layers; the 64 KB RAM handles packet buffers and data arrays without external memory. If the firmware grows beyond 256 KB, a pin-compatible upgrade in the same family with larger Flash exists — but that part is also obsolete. The 100-LQFP (14x14 mm) is a standard fine-pitch QFP; it reflows without special handling as long as the MSL rating (not listed here, but typical for this package class is MSL 3) is respected. Bake it if the floor life has been exceeded — popcorning in a 100-pin QFP is a panel killer.","metaTitle":"LM3S6952-IQC50-A2 Stellaris ARM Cortex-M3 MCU, 50 MHz, 256 KB Flash","metaDescription":"LM3S6952-IQC50-A2 Stellaris ARM Cortex-M3 MCU, 50 MHz, 256 KB Flash, 64 KB RAM, Ethernet, -40°C to 85°C.
