It packs 256 KB of Flash, 32 KB of SRAM, and 2 KB of EEPROM in a 100-pin LQFP package, rated for -40 to 85 °C industrial environments. The part is aimed at real-time control, sensor fusion, and communication gateway applications where the FPU accelerates PID loops or FFT math without an external DSP.
Memory map — Flash, RAM, and the EEPROM edge
The 2 KB EEPROM stores parameters without wearing the Flash.
Peripheral set — CAN, USB OTG, and serial flexibility
The CAN interface makes this MCU a natural fit for industrial automation gateways or automotive body controllers. USB OTG allows direct connection to a flash drive for data logging or to a PC for firmware updates without an external USB-serial bridge. The 69 GPIOs in the 100-LQFP package leave room for a parallel LCD interface or a bank of opto-isolated inputs alongside the serial buses.
For BOM planning, the base product number TM4C1237 covers multiple Flash/RAM density variants in the same 100-LQFP footprint, so a pin-compatible upgrade path exists within the family if firmware grows.
