Product details
Overview
TMS320F28032PNTR from Texas Instruments is a 60-MHz C28x-core real-time microcontroller with integrated control peripherals, designed for closed-loop motor and power conversion systems. It delivers 16.67-ns instruction cycle time, 32 KB on-chip Flash, 10 KB SARAM, and supports ePWM, HRPWM, eCAP, eQEP, 12-bit ADC (4.6 MSPS), and dual comparators - enabling high-precision digital control in DC/DC converters and EV charging modules.
For engineers reviewing the TMS320F28032PNTR datasheet, TMS320F28032PNTR pinout, TMS320F28032PNTR application, or TMS320F28032PNTR equivalent, key selection criteria include its 80-pin LQFP package, CLA-free architecture, 32 KB Flash/10 KB RAM memory map, -40°C to 105°C industrial temperature grade, and native support for eCAN, LIN, SPI, I²C, and UART interfaces in real-time control firmware development.
Technical Context
The TMS320F28032PNTR implements a Harvard-architecture 32-bit C28x CPU with atomic operations and fast interrupt response, paired with a unified memory model for efficient C/C++ execution. Its peripheral set centers on deterministic timing: three 32-bit CPU timers, 8 ePWM channels (including 4 high-resolution), one eQEP module, and a 12-bit ADC with 16 input channels and dual sample-and-hold.
Control-specific hardware includes analog comparators with internal 10-bit references routed directly to PWM trip zones, HRPWM dual-edge modulation capability, and PIE-integrated interrupt handling for all peripherals. The device lacks a Control Law Accelerator (CLA), distinguishing it from F28033/F28035 variants, and uses a single 3.3-V supply with integrated POR/BOR and voltage regulator.
