On-chip peripherals include brown-out detect/reset, POR, PWM, and a watchdog timer; two 10-bit ADC channels provide basic analog input for voltage or current sensing. No second-source cross-reference exists from TI.","metaTitle":"Texas Instruments LM3S1512-EQC25-A2T ARM Cortex-M3 MCU","metaDescription":"Texas Instruments LM3S1512-EQC25-A2T Stellaris ARM Cortex-M3 MCU, 25 MHz, 96 KB flash, 64 KB SRAM, 100-LQFP.
