80 MHz Cortex-M4F with floating-point unit
The TM4C1237D5PMI7R is a Texas Instruments Tiva C series 32-bit ARM Cortex-M4F microcontroller clocked at 80 MHz. The single-cycle multiply-accumulate and single-precision floating-point unit handle sensor fusion and motor-control math without a separate DSP. On-chip memory breaks down as 64 KB Flash for program storage, 24 KB SRAM for data, and 2 KB EEPROM for calibration constants or fault logs. The 64-LQFP package (10x10 mm) gives 43 I/O lines, enough for a CAN node with USB OTG and several serial peripherals.
