TM4C1230C3PMI7R ARM Cortex-M4F MCU | 80MHz Tiva C Microcontroller for Industrial & IoT
The TM4C1230C3PMI7R is a 32-bit ARM Cortex-M4F microcontroller from Texas Instruments' Tiva C series, delivering 80MHz processing power with a single-precision FPU for demanding embedded applications. The chip ships with 32KB Flash, 12KB SRAM, and 2KB EEPROM, alongside a rich peripheral set: CANbus, 12-bit ADC, multiple timers, and 9 communication interfaces (UART/I²C/SPI/SSI).
The 1.08V-3.63V wide voltage range and integrated low-power modes make this MCU the right choice for industrial controls, IoT edge nodes, and automotive subsystems where flexible supply rails and tight energy budgets matter. Encased in a compact 64-LQFP (10×10mm) package, it offers 49 programmable I/Os for flexible system integration.
1.08V-3.63V Wide Voltage Range with FPU for Embedded Control Systems
- Cortex-M4F core with FPU — single-precision floating-point hardware for control loops and filtering.
- 80MHz clock speed — sufficient throughput for real-time industrial control tasks.
- 32KB Flash + 12KB SRAM + 2KB EEPROM — ample memory for application code, runtime data, and configuration storage.
- 12-bit ADC with 12 channels — precise analog signal acquisition for sensor-based applications.
- CAN, I²C × 2, SPI × 2, UART × 3, SSI — broad connectivity for industrial bus and peripheral integration.
- Built-in brown-out reset and watchdog — keeps deployed systems recoverable through abnormal events.
Where the TM4C1230C3PMI7R Fits
The Tiva C family is widely used in PLC I/O processors, sensor hubs, motor controllers, BMS firmware, and any embedded system where Cortex-M4F throughput, CAN connectivity, and integrated EEPROM make the BoM tighter. The wide 1.08V-3.63V supply range allows direct operation from battery rails and standard 3.3V logic without external pre-regulation, and the LQFP64 footprint is reflowable on standard PCBA lines.
