Product details
Overview
TMS320F28032PNT from Texas Instruments is a 32-bit C28x real-time microcontroller with 60MHz CPU, integrated 12-bit ADC (4.6 MSPS), 8 ePWM channels, 1 eQEP module, and 1 eCAN interface - designed for closed-loop motor control in industrial inverters and EV charging power modules.
For engineers reviewing the TMS320F28032PNT datasheet, TMS320F28032PNT pinout, TMS320F28032PNT application, or TMS320F28032PNT equivalent, key selection criteria include its 64-pin TQFP package, CLA absence, 32KB Flash/10KB SARAM memory configuration, and automotive-qualified (-Q1) variant availability for safety-critical power conversion systems.
Technical Context
The TMS320F28032PNT implements a Harvard-architecture C28x CPU with atomic operations and fast interrupt response, paired with peripheral-integrated control logic including HRPWM for dual-edge modulation and analog comparators routed directly to PWM outputs. Its ADC supports ratio-metric VREFHI/VREFLO references and 16-channel sampling at 4.6 MSPS with 216.67 ns conversion time.
It features a dedicated PIE block managing all peripheral interrupts, three 32-bit CPU timers, and serial interfaces including SCI (UART), two SPIs, I²C, LIN, and eCAN - all accessible via multiplexed GPIO with input filtering and programmable pullups. The device lacks the Control Law Accelerator (CLA) present in F28033/F28035 variants.

FAQ
What is the maximum operating frequency of the TMS320F28032PNT?
The TMS320F28032PNT operates at a maximum CPU frequency of 60 MHz, corresponding to a 16.67 ns instruction cycle time. This speed is achieved using the internal PLL with an external crystal or clock source applied to X1/X2 or XCLKIN. The device maintains timing integrity across its full –40°C to 105°C operating range without derating.
Does the TMS320F28032PNT include a Control Law Accelerator (CLA)?
No, the TMS320F28032PNT does not include a CLA. The CLA is present only in the TMS320F28033PNT and TMS320F28035PNT variants. The TMS320F28032PNT relies solely on its C28x CPU for control law execution, making it suitable for cost-sensitive applications where CLA-level parallelism is not required.
What ADC performance specifications apply to the TMS320F28032PNT?
The TMS320F28032PNT integrates a 12-bit SAR ADC with 4.6 MSPS sampling rate and 216.67 ns conversion time. It supports 16 input channels across two banks (ADCINA/ADCINB), ratio-metric referencing via VREFHI/VREFLO, and dual sample-and-hold capability for simultaneous sampling of up to two signals.
Which communication interfaces are available on the TMS320F28032PNT in the 64-pin TQFP package?
In the 64-pin PAG TQFP package, the TMS320F28032PNT supports one eCAN module, one SCI (UART-compatible), two SPI modules, one I²C module, and one LIN module. All interfaces are fully functional and mapped to dedicated pins per the device's signal description table and pin diagram.
Is the TMS320F28032PNT pin-compatible with other F2803x family members in the same package?
Yes, the TMS320F28032PNT is pin-compatible with other F2803x devices in the 64-pin PAG TQFP package, including TMS320F28030PNT, TMS320F28031PNT, TMS320F28033PNT, and TMS320F28034PNT. Peripheral pin mappings and power/ground assignments are identical; differences are limited to internal memory size, CLA presence, and ADC channel count - all software-configurable.
