The TM4C1237H6PMI7R is a Texas Instruments Tiva C series microcontroller built around an ARM Cortex-M4F core with a single-precision floating-point unit, clocked at 80 MHz. That FPU is the differentiator versus a plain Cortex-M3 — it handles sensor fusion, PID coefficients, and FFT bins without software emulation, so the loop stays deterministic. Program memory is 256 KB of Flash, backed by 32K x 8 SRAM and 2K x 8 EEPROM, which is enough for a Modbus TCP-to-CAN gateway or a small HMI panel running a real-time OS.
Connectivity and I/O — CAN and USB OTG on a single chip
The 12-channel 12-bit ADC (A/D 12x12b) captures analog sensor inputs without an external converter. With 43 I/O lines in a 64-LQFP package, the pin count is tight for a multi-interface design but workable if you multiplex the lower-speed buses.
Supply range is 1.08 V to 3.63 V.
Lifecycle and sourcing — what the record shows
One source marks the part as end-of-life hot; another lists the product status as Active. For a firm commitment, submit an RFQ.
