The 80 MHz core clock gives it the throughput for real-time control loops and sensor fusion without an external DSP. The 128 KB on-chip Flash and 32K x 8 SRAM provide enough headroom for a modest firmware stack with a small RTOS, while the 2K x 8 EEPROM space holds calibration constants or configuration parameters that survive a power cycle without needing external storage.
The 22-channel 12-bit ADC (A/D 22x12b) samples analog inputs from current sensors, thermocouples, or potentiometers without an external converter. The Brown-out Detect/Reset, DMA, POR, and WDT peripherals handle supply monitoring and fault recovery on-chip. With 69 I/O lines in the 100-LQFP package, there is enough GPIO for a parallel LCD bus, keypad matrix, and a few status LEDs alongside the serial interfaces.
Package and procurement — 100-LQFP (14x14 mm), active lifecycle
For buyers verifying component authenticity: the laser-etched marking on the 100-LQFP body should show the TI logo, the base part number TM4C1231, and a date-code consistent with the reel label. Any sanded or re-marked surface is a red flag. Sourced through independent distribution, each reel is traceable back to the authorized TI channel.
