The 128 KB Flash and 32K x 8 RAM footprint fits moderate-complexity firmware: a CANopen stack plus a PID loop and a Modbus RTU slave, for example, without squeezing. The 2K x 8 EEPROM holds calibration constants and boot-config parameters that survive a firmware update. ## Industrial temperature grade and connectivity The peripheral set includes CANbus, I²C, SPI, SSI, UART, and QEI — the quadrature encoder interface is a direct fit for reading incremental encoder position in a servo axis without external logic. The 22-channel 12-bit ADC on board handles current sensing on three motor phases plus a few analog inputs for temperature and voltage monitoring. Brown-out detect and POR are integrated, so a separate supervisor IC is optional for most designs. ## 100-LQFP package — board fit and routing The 100-LQFP (14x14 mm) gives 69 general-purpose I/O. That is enough for a parallel LCD data bus, encoder channels, CAN and UART transceiver control, and pushbutton/LED lines on a 4-layer board. ## Lifecycle status — EOL hot, plan the BOM transition","metaTitle":"Texas Instruments TM4C123BE6PZIR Tiva C ARM Cortex-M4F MCU, 80 MHz","metaDescription":"TI TM4C123BE6PZIR Tiva™ C series 32-bit MCU with ARM Cortex-M4F core at 80 MHz, 128 KB Flash, 32K x 8 RAM, 100-LQFP.
