It packs 128 KB of Flash, 32 KB of RAM, and 2 KB of EEPROM on-chip — enough for a moderate control loop with some data logging or a small protocol stack. The 43 I/O lines break out to CAN, SPI, I²C, UART, and a 22-channel 12-bit ADC, making it a natural fit for industrial sensor hubs, motor-control interface boards, and CAN-bus gateway modules that need to live in a -40°C to 85°C enclosure.
The 80 MHz Cortex-M4F core includes a hardware FPU for single-cycle MAC and divide operations.
80 MHz, running on an ARM Cortex-M4F core with single-precision FPU.
It is part of the Tiva C series from Texas Instruments.
