TM4C123AE6PMI Technical Specifications

TM4C123AE6PMI Key Features

• High?performance Cortex?M4F core: provides hardware floating?point and DSP instructions for faster control loops and sensor processing.
• Large on?chip flash and SRAM: 256 KB flash and 32 KB SRAM reduce the need for external memory, simplifying BOM and board area.
• Rich peripheral set: multiple UARTs, SSI (SPI), I2C, USB and timers enable direct interfacing to sensors, actuators and host systems.
• 12?bit ADC: multi?channel analog inputs support higher resolution sensing for measurement and control tasks.
• Power and integration: integrated power domain and sleep modes lower system complexity and help manage power for battery?assisted applications.
• Compact package: 64?pin LQFP provides a balance between pin count and PCB space for medium?density designs.

Typical Applications

• Industrial motor control systems requiring deterministic real?time control and integrated PWM, timers and ADC functionality for closed?loop performance.
• Human?machine interface (HMI) panels where USB connectivity, multiple serial ports and sufficient on?chip memory support graphical displays and touch input.
• Sensor aggregation and edge processing nodes that need a hardware FPU and DSP instructions for filtering, sensor fusion and condition monitoring algorithms.
• Embedded communication gateways and protocol translators leveraging multiple UART, SPI/SSI and I2C ports plus USB host/device support for system integration.

TM4C123AE6PMI Advantages vs Typical Alternatives

The device combines a dedicated Cortex?M4F core with floating?point support and a larger on?chip memory footprint than many 32?bit competitors. This yields faster numeric processing and fewer external components compared with solutions that require external memory or DSP co?processors. Integrated USB, multiple serial interfaces and a full analog front end reduce board complexity and BOM cost, making it more efficient for mid?range embedded control than smaller microcontrollers lacking peripherals.
