90 MHz C28x core with 128 KB flash — real-time control headroom
The TMS320F28062FPNT is a Texas Instruments C2000 C28x Piccolo MCU running at 90 MHz with a 32-bit single-core C28x processor. The 128 KB on-chip flash (64K x 16) and 26K x 16 RAM provide enough code and data space for a three-phase motor control loop, a digital power PFC stage, or a multi-axis servo commutation routine without external memory. The 12-channel 12-bit ADC maps to three-phase current sensing plus DC bus voltage and auxiliary inputs — a single part covers the analog front-end for a field-oriented control (FOC) algorithm.
Peripheral set and connectivity for drive and power applications
On-chip peripherals include PWM channels, a watchdog timer, brown-out detect, POR, and DMA — the PWM module is the key block for generating complementary gate-drive signals with dead-band insertion. The connectivity suite (CANbus, I2C, McBSP, SCI, SPI, UART/USART) ties the MCU to a fieldbus gateway, encoder interface, or isolated SPI ADC. The 40 general-purpose I/O are multiplexed with the peripheral functions; the 80-LQFP package (12x12 mm) breaks out enough pins for a typical motor-drive BOM without a larger footprint. Supply voltage range 1.71 V to 1.995 V means a single 1.8 V rail or an LDO from a 3.3 V bus powers the core.
