Product details
Overview
TMS320F28031PAGQ from Texas Instruments is a 60-MHz C28x-core real-time microcontroller with integrated control peripherals, designed for motor control and digital power applications. It delivers 16.67-ns instruction cycle time, 32-bit floating-point CLA acceleration, 32 KB on-chip Flash, 8 KB SARAM, and supports automotive-grade operation from –40°C to 125°C (AEC Q100 qualified). Its ePWM, HRPWM, ADC, comparators, and eCAN enable closed-loop control in EV charging modules and industrial inverters.
For engineers reviewing the TMS320F28031PAGQ datasheet, TMS320F28031PAGQ pinout, TMS320F28031PAGQ application, or TMS320F28031PAGQ equivalent, key selection considerations include its 64-pin TQFP package, 12-bit 4.6-MSPS ADC with dual sample-and-hold, 12 ePWM channels, 3 analog comparators with DACs, and AEC Q100 qualification for automotive power electronics.
Technical Context
The TMS320F28031PAGQ implements a Harvard-architecture C28x CPU executing at 60 MHz with atomic operations and fast interrupt response. Its CLA operates independently of the main CPU to offload control-law computations using 32-bit floating-point math.
Peripheral integration includes 12 ePWM channels with high-resolution capability (dual-edge modulation), 12-channel 12-bit ADC with 216.67-ns conversion time and ratio-metric reference support, and three analog comparators with internal 10-bit references routed directly to PWM trip zones.

FAQ
What is the maximum operating frequency of the TMS320F28031PAGQ?
The TMS320F28031PAGQ operates at a maximum CPU frequency of 60 MHz, corresponding to a 16.67-ns instruction cycle time. This frequency is generated by the internal PLL from an external crystal (4–20 MHz) or clock source connected to X1/X2 pins. The device maintains this speed across its full operating temperature range of –40°C to +125°C.
Does the TMS320F28031PAGQ include a Control Law Accelerator (CLA)?
No, the TMS320F28031PAGQ does not include a Control Law Accelerator. According to the official device comparison table, CLA is present only in TMS320F28033 and TMS320F28035 variants. The TMS320F28031PAGQ relies solely on its C28x CPU for control-law execution, making it suitable for applications where CLA offload is not required.
What ADC performance does the TMS320F28031PAGQ provide?
The TMS320F28031PAGQ integrates a 12-bit analog-to-digital converter with 4.6 MSPS throughput, 12 input channels, and 216.67-ns conversion time. It supports dual sample-and-hold and ratio-metric referencing using VREFHI/VREFLO, enabling accurate current/voltage sensing in noisy power-conversion environments.
Is the TMS320F28031PAGQ qualified for automotive applications?
Yes, the TMS320F28031PAGQ carries the "Q" suffix indicating AEC Q100 qualification for automotive use. It is rated for operation from –40°C to +125°C and meets enhanced ESD requirements (±2-kV HBM, ±500-V CDM), making it suitable for under-hood power electronics including EV charging modules and traction inverters.
How many ePWM channels does the TMS320F28031PAGQ support?
The TMS320F28031PAGQ supports 12 ePWM channels, each with dedicated time-base, counter-compare, and action qualifier modules. All 12 channels include high-resolution extension (HRPWM) capability for sub-nanosecond edge placement-critical for high-frequency GaN/SiC-based power stages in DC/DC and inverter designs.
