Product details
Overview
TMS320F28026FPTQ from Texas Instruments is a C28x-core 32-bit real-time control microcontroller designed for motor and power conversion systems. It operates at 60 MHz (16.67-ns cycle time), integrates 16 KB flash, 6 KB SARAM, 8 KB boot ROM, and features 8 ePWM channels with 4 high-resolution outputs, 12-bit ADC (3 MSPS, 7 channels), and dual comparators with integrated DACs. It targets automotive-grade inverter control in AC-input BLDC motor drives.
For engineers reviewing the TMS320F28026FPTQ datasheet, TMS320F28026FPTQ pinout, TMS320F28026FPTQ application, or TMS320F28026FPTQ equivalent, key selection criteria include its AEC Q100-qualified –40°C to 125°C operation, InstaSPIN-FOC™ enablement, 48-pin LQFP package with GPIO multiplexing, and integrated analog peripherals for closed-loop timing-critical control.
Technical Context
The TMS320F28026FPTQ implements the C28x CPU core with Harvard architecture, atomic instructions, and unified memory model for deterministic real-time execution. Its clock system includes dual zero-pin oscillators, on-chip crystal oscillator support, and missing-clock detection - enabling robust timing in automotive power stages.
Peripheral integration centers on control-specific functions: four ePWM modules each with independent 16-bit timers and HRPWM capability, two analog comparators routed directly to PWM trip zones, and a 12-bit ADC with dual sample-and-hold supporting ratio-metric VREFHI/VREFLO references and low-latency conversion for current sensing.
