TM4C1230H6PMI Key Features

• ARM Cortex?M4F core with floating point unit for faster math and signal processing compared with Cortex?M0 alternatives.
• Up to 80 MHz clock to reduce execution time and increase throughput for real?time control and communication tasks.
• Multiple serial buses (UART, SSI/SPI, I2C, USB) to simplify sensor, actuator, and host interfaces while reducing external components.
• Two 12?bit ADCs that provide higher resolution analog sampling than typical 8?bit ADCs, improving measurement accuracy for control loops.
• Rich PWM and timer resources to drive motors and power stages with finer resolution and deterministic timing compared with basic timer MCUs.
• 64?pin package density that offers more I/O and peripheral pins than smaller packages, while keeping board area moderate versus larger 100+ pin parts.
• Embedded flash and SRAM for code and data storage that streamlines system BOM by avoiding external memory in many applications.

Typical Applications

• Industrial motor control and basic servo systems where deterministic PWM and 12?bit ADC feedback are required for stable closed?loop performance over temperature.
• Human?machine interfaces and control panels that need multiple UART and I2C links for displays, keypads, and peripheral sensors with reduced component count.
• Embedded communications gateways that aggregate sensor data via SPI/I2C and forward it over USB or serial links with adequate CPU headroom.
• Prototyping and educational development on 64?pin boards, offering more GPIO and peripherals than minimal MCUs while remaining cost?effective for production.

TM4C1230H6PMI Advantages vs Typical Alternatives

The device delivers more computational power and peripheral density than typical 8? or 16?bit MCUs. With a floating?point?capable Cortex?M4F and up to 80 MHz, it executes DSP and control algorithms faster and with fewer clock cycles. Integrated dual 12?bit ADCs, multiple UART/SSI/I2C ports, and a USB interface reduce the need for external parts and simplify board design. The 64?pin package balances I/O count and PCB area better than larger 100+ pin devices while offering far more integration than minimalist 28?pin MCUs.
