Peripheral set includes a 16-channel 10-bit ADC, PWM timers, DMA, and a quadrature encoder interface for motor-control feedback. The part is specified over the industrial temperature range of -40°C to 85°C and operates from a 1.08 V to 1.32 V core supply. It is housed in a 108-ball BGA package (10x10 mm). The 80 MHz Cortex-M3 core provides 80 DMIPS. The 24 KB SRAM limits buffered applications. ## Obsolete — sourcing reality and what replaces it Texas Instruments has marked the LM3S5P3B-IBZ80-C5T as obsolete.","metaTitle":"LM3S5P3B-IBZ80-C5T Stellaris ARM Cortex-M3 MCU, 80MHz, 64KB Flash","metaDescription":"Texas Instruments LM3S5P3B-IBZ80-C5T is an obsolete 32-bit ARM Cortex-M3 MCU from the Stellaris 5000 series. 80MHz core, 64KB Flash, 24KB RAM, 67 I/O, CAN/USB, -40 to 85°C.
