The 256 KB Flash and 32K x 8 RAM give enough room for a real-time OS kernel, CANopen stack, and a modest data log buffer. 105 I/O lines break out to the 144-LQFP package, enough to capture encoder quadrature (QEI), drive a parallel LCD, and still leave pins for limit switches and status LEDs. ## Industrial temperature range — enclosure realities Supply range 1.08 V to 3.63 V. ## EOL status — sourcing plan required ## Connectivity and analog — fieldbus and sensor front-end CAN, I²C, SPI, SSI, UART, and IrDA cover the common industrial interfaces: CAN for drive networks, SPI for external ADC/DAC, UART for Modbus RTU. The 24-channel 12-bit ADC samples analog inputs from thermocouples or current shunts without an external mux — one chip handles both the logic and the analog front-end.","metaTitle":"TM4C123BH6PGEIR Tiva C ARM Cortex-M4F MCU, 80 MHz, 256 KB Flash","metaDescription":"TM4C123BH6PGEIR Tiva C series 32-bit ARM Cortex-M4F MCU. 80 MHz, 256 KB Flash, 32K x 8 RAM, 105 I/O, industrial temp.
