TM4C1231H6PMI 32-bit ARM Cortex-M4 Microcontroller, 64-pin LQFP

TM4C1231H6PMI Overview

The TM4C1231H6PMI is a 32-bit microcontroller built on an ARM Cortex-M4F core. It targets real-time control and connected embedded systems that need higher numeric performance and lower latency. Operating at up to 80 MHz, the device balances compute and peripheral density for industrial and consumer designs. Onboard mixed-signal peripherals and standard serial interfaces help shorten designs and reduce bill-of-materials compared with separate controller plus peripheral ICs.

TM4C1231H6PMI Key Features

• ARM Cortex-M4F core with single-precision FPU delivers faster math and signal processing compared with Cortex-M3 alternatives.
• Up to 80 MHz system clock for higher throughput in control loops and communication stacks.
• Integrated 12-bit ADC enables accurate sensor acquisition without external converters, reducing component count.
• Multiple serial interfaces (UART, SPI, I2C, SSI) simplify system integration across faster and legacy buses.
• Rich GPIO set and flexible timer/PWM resources facilitate motor control, power management, and human-machine interfaces.
• Industrial temperature rating supports deployment in harsher environments compared with consumer-grade parts.

Typical Applications

• Industrial motor control modules requiring deterministic loop timing and floating-point math for PID control, position and speed regulation, and sensor fusion.
• Embedded HMI and control panels that need multiple UART/SPI/I2C peripherals for displays, keypads, and external sensors with compact BOM.
• Portable instruments where 12-bit ADC accuracy, low-voltage operation, and an integrated MCU reduce the need for discrete converters and regulators.
• Networked sensors and edge nodes that combine local signal processing with standard serial links to gateways, offering lower latency than offloaded solutions.

TM4C1231H6PMI Advantages vs Typical Alternatives

The part pairs a floating-point Cortex-M4F core with integrated analog and serial peripherals, offering more on-chip functionality than many Cortex-M0/M3 options. At 80 MHz and with built-in 12-bit ADC, it often replaces a microcontroller plus ADC combo, lowering board area and reducing BOM costs. Industrial temperature operation and a 64-pin LQFP give a compact footprint while supporting considerable I/O and timing resources compared with smaller-pin devices.
