The TM4C1231H6PZI microcontroller is a 32-bit Arm Cortex-M4F-based MCU with 80-MHz, 256-kb Flash, 32-kb RAM, CAN, RTC, 100-pin LQFP.

• 32-bit ARM? Cortex?-M4 80-MHz processor core with System Timer (SysTick), integrated Nested Vectored Interrupt Controller (NVIC), Wake-Up Interrupt Controller (WIC) with clock gating, Memory Protection Unit (MPU), IEEE754-compliant single-precision Floating-Point Unit (FPU), Embedded Trace Macro and Trace Port, System Control Block (SCB) and Thumb-2 instruction set

  
  

• On-chip memory, featuring 256 KB single-cycle Flash up to 40 MHz (a prefetch buffer improves performance above 40 MHz), 32 KB single-cycle SRAM; internal ROM loaded with TivaWare? for C Series software; 2KB EEPROM

  
  

• One Controller Area Network (CAN) module, using CAN protocol version 2.0 part A/B and with bit rates up to 1 Mbps

  
  

• ARM PrimeCell? 32-channel configurable μDMA controller, providing a way to offload data transfer tasks from the Cortex?-M4 processor, allowing for more efficient use of the processor and the available bus bandwidth

  
  

• Industrial-range (-40°C to 85°C) RoHS-compliant 100-pin LQFP
