Product details
Overview
TMS320F28033P1PAGS from Texas Instruments is a 60-MHz C28x-core real-time microcontroller with integrated Control Law Accelerator (CLA), 32 KB flash, 10 KB SARAM, 14-channel 12-bit ADC (4.6 MSPS), 14 ePWM channels (7 with high-resolution capability), and dual comparators with DACs - deployed in EV charging power modules, solar string inverters, and industrial AC-DC converters.
For engineers reviewing the TMS320F28033P1PAGS datasheet, TMS320F28033P1PAGS pinout, TMS320F28033P1PAGS application, or TMS320F28033P1PAGS equivalent, key selection criteria include CLA offload capability for real-time control loops, HRPWM dual-edge modulation support, analog integration (ADC + comparators + temperature sensor), and TQFP-64 packaging for space-constrained motor drive PCBs.
Technical Context
The TMS320F28033P1PAGS implements a Harvard-architecture C28x CPU with atomic instruction execution and zero-wait-state memory access, enabling deterministic 16.67 ns cycle-time control. Its CLA operates independently of the CPU using shared 32-bit floating-point math resources to accelerate PID and observer algorithms.
Peripheral integration includes ePWM modules with EPWMSYNCI/EPWMSYNCO synchronization signals, HRCAP for sub-nanosecond edge capture, and ADC with dual sample-and-hold supporting simultaneous sampling across 14 input channels - all coordinated via the PIE interrupt controller and mapped to 33 GPIO pins with programmable filtering.
