80 MHz Cortex-M4F with FPU — compute headroom for control and signal processing
Program memory is 128 KB of Flash, backed by 32 KB of SRAM and 2 KB of EEPROM for non-volatile parameter storage. On-chip peripherals include a 12-channel 12-bit ADC, CAN, multiple I²C/SPI/UART serial interfaces, and USB connectivity — all in a 64-pin LQFP package with 49 general-purpose I/O lines. The 80 MHz core with FPU means this part can run a sensor-fusion algorithm or a motor-control loop without offloading to a separate DSP — the floating-point unit handles single-precision multiply-accumulate in a single cycle. The 128 KB Flash is sized for firmware that fits a moderate-complexity application: a CANopen stack, a USB device class driver, and a control loop will leave headroom for field updates, but a full GUI stack or extensive data-logging will push you toward the higher-density siblings.
Pinout and package — 64-LQFP, 10×10 mm body
The TM4C1232E6PMI7R comes in a 64-lead LQFP package (supplier device package 64-LQFP, 10×10 mm body). The pinout is shared across the TM4C1232 family base product number.
