The 20 KB SRAM leaves room for a few kilobytes of stack and a double-buffered data array after the RTOS kernel overhead. ## Industrial temperature and peripheral set On-chip peripherals include an 8-channel 10-bit ADC, PWM, DMA, and watchdog timer — enough to close a motor-control loop or read multiple analog sensors without external components. The connectivity block covers I²C, SPI, UART, LIN, IrDA, and SSI, so it can talk to a fieldbus bridge, a serial EEPROM, and an actuator driver on the same board. 33 general-purpose I/O pins in the 64-LQFP package leave room for a parallel LCD interface or a keypad matrix alongside the serial buses. The 10x10 mm body fits a standard 4-layer PCB layout with 0.5 mm pitch. Texas Instruments has marked the LM3S1J16-IQR50-C3 as obsolete. For a BOM line that already carries this part, the available stock is held in independent surplus and excess channels. Each reel is lot-traceable and sourced against an RFQ — no franchised inventory remains in the primary distribution pipeline.","metaTitle":"Texas Instruments LM3S1J16-IQR50-C3 MCU, 50MHz, 128KB Flash","metaDescription":"Texas Instruments Stellaris LM3S1J16-IQR50-C3 ARM Cortex-M3 MCU, 50MHz, 128KB FLASH, 20K x 8 RAM, 64-LQFP, -40°C~85°C.
