Product details
Overview
TMS320F28034PNQ from Texas Instruments is an AEC-Q100 qualified 32-bit C28x real-time microcontroller with 60MHz CPU, CLA accelerator, 32KB on-chip Flash, 10KB SARAM, and integrated analog peripherals including 12-bit 4.6 MSPS ADC (16 channels), 3 comparators with DACs, ePWM (14 channels), HRPWM (7 channels), eCAP, eQEP, and eCAN. It targets automotive-grade motor control in EV charging modules and onboard converters.
For engineers reviewing the TMS320F28034PNQ datasheet, TMS320F28034PNQ pinout, TMS320F28034PNQ application, or TMS320F28034PNQ equivalent, key selection criteria include AEC-Q100 qualification, 80-pin LQFP package with 45 GPIOs, dual-sample-and-hold ADC timing, CLA offloading capability, and automotive temperature range (–40°C to 125°C).
Technical Context
The TMS320F28034PNQ implements a Harvard-architecture C28x CPU with atomic instructions and fast interrupt response, paired with a dedicated 32-bit floating-point CLA that executes control law code independently of the main CPU. Its memory subsystem includes 32KB secure Flash, 10KB SARAM (0-wait), 8KB Boot ROM, and 1KB OTP - all protected by a 128-bit security key and lock.
Peripheral integration centers on high-resolution real-time control: ePWM modules support dual-edge modulation via HRPWM; ADC features 16 input channels, 4.6 MSPS sampling, and ratio-metric VREFHI/VREFLO references; analog comparators route directly to PWM trip zones for hardware-based protection; and eCAN, LIN, SPI, I²C, and SCI provide robust communication for automotive subsystems.
