Texas Instruments TMS32F28032LENAPNS

Overview

TMS320F28032LENAPNS from Texas Instruments is a 60-MHz C28x-core real-time microcontroller with integrated control peripherals, designed for digital power and motor control systems. It features 32 KB on-chip Flash, 10 KB SARAM, 3× 32-bit CPU timers, 8 ePWM channels, 16-channel 12-bit ADC (4.6 MSPS), and eCAN, SPI, I²C, LIN, and SCI interfaces. It operates from a single 3.3-V supply and targets inverter gate drive, DC/DC converter control, and EV charging power modules.

For engineers reviewing the TMS320F28032LENAPNS datasheet, TMS320F28032LENAPNS pinout, TMS320F28032LENAPNS application, or TMS320F28032LENAPNS equivalent, key selection criteria include its 64-pin TQFP package, CLA absence, 8 ePWM channels, 16 ADC inputs, and -40°C to 105°C industrial temperature rating - critical for embedded power conversion design validation.

Technical Context

The TMS320F28032LENAPNS implements a Harvard-architecture C28x CPU executing at 60 MHz (16.67 ns cycle time) with atomic operations and fast interrupt response. Its peripheral set includes ePWM with high-resolution capability, eCAP, eQEP, and HRCAP modules - all accessible via a unified memory-mapped register space and coordinated through the PIE interrupt controller.

It integrates analog functions including a 12-bit ADC with dual sample-and-hold, three comparators with internal DACs, and an on-chip temperature sensor. Clocking is supported by dual zero-pin oscillators, external crystal input, and missing-clock detection - enabling robust timing in isolated power stage environments without external clock sources.

FAQ

What is the maximum operating frequency of the TMS320F28032LENAPNS?

The TMS320F28032LENAPNS operates at a maximum CPU frequency of 60 MHz, corresponding to a 16.67 ns instruction cycle time. This timing is guaranteed across its full industrial temperature range (–40°C to 105°C) and 3.3-V supply, enabling deterministic execution of control loops with sub-microsecond latency - a requirement verified in TI's SPRS584Q datasheet revision January 2024.

Does the TMS320F28032LENAPNS include a Control Law Accelerator (CLA)?

No, the TMS320F28032LENAPNS does not include a CLA. Per Table 4-1 in the official datasheet, CLA is present only in the TMS320F28033 and TMS320F28035 variants. The TMS320F28032LENAPNS relies solely on its C28x CPU for control law computation, making it suitable for applications where computational load fits within the 60-MHz core bandwidth without hardware acceleration.

What package type and pin count does the TMS320F28032LENAPNS use?

The TMS320F28032LENAPNS uses a 64-pin Thin Quad Flatpack (TQFP) package, designated as PAG in TI's ordering nomenclature. Its mechanical dimensions are 10.0 mm × 10.0 mm with 0.5-mm lead pitch. This package is confirmed in TI's "Mechanical, Packaging, and Orderable Information" section and matches the pin diagram shown in Figure 5-2 of the SPRS584Q datasheet.

How many ePWM channels does the TMS320F28032LENAPNS support?

The TMS320F28032LENAPNS supports 8 ePWM channels, organized as four independent ePWM modules (EPWM1–EPWM4), each providing complementary A/B outputs. This configuration is explicitly listed in Table 4-1 of the datasheet and enables full-bridge or three-phase inverter control with integrated dead-time generation and trip-zone protection - critical for safe gate-driver interfacing.

What is the ADC resolution and sampling rate of the TMS320F28032LENAPNS?

The TMS320F28032LENAPNS integrates a 12-bit analog-to-digital converter with 16 input channels and a maximum sampling rate of 4.6 MSPS, achieving a minimum conversion time of 216.67 ns. It includes dual sample-and-hold circuitry, allowing simultaneous sampling of two channels - a feature confirmed in the Device Comparison table and Functional Description sections of the SPRS584Q datasheet.
