Texas Instruments TMS320F28054MPNQ

Overview

TMS320F28054MPNQ from Texas Instruments is a 60-MHz C28x-core real-time microcontroller with integrated analog front end (7 comparators, 4 PGAs, 12-bit ADC), ePWM (14 channels), eCAN, and dual-zone security-designed for automotive-grade motor control in air conditioner outdoor units and BLDC drives.

For engineers reviewing the TMS320F28054MPNQ datasheet, TMS320F28054MPNQ pinout, TMS320F28054MPNQ application, or TMS320F28054MPNQ equivalent, key selection criteria include AEC Q100 qualification, 80-pin LQFP package, 3.3-V single-supply operation, CLA absence, and 32K flash/10K SARAM memory configuration specific to the F28054M variant.

Technical Context

The TMS320F28054MPNQ implements a Harvard-architecture C28x CPU executing at 60 MHz (16.67-ns cycle time) with atomic operations and fast interrupt response. It integrates a 12-bit ADC (3.75 MSPS, 16 channels, dual sample-and-hold) and analog peripherals including seven comparators-three with internal 6-bit DAC references-and four programmable gain amplifiers (gain ≈ 3, 6, or 11).

Its control subsystem includes 14 ePWM channels with dead-band and trip-zone support, one eCAP, one eQEP, three 32-bit CPU timers, and serial interfaces: three SCI/UARTs, one SPI, one I²C, and one eCAN. The device uses an internal voltage regulator enabling single 3.3-V rail operation and supports AEC Q100 Grade 1 (–40°C to 125°C) automotive qualification.

FAQ

What is the maximum operating frequency of the TMS320F28054MPNQ?

The TMS320F28054MPNQ operates at a maximum CPU frequency of 60 MHz, corresponding to a 16.67-ns instruction cycle time. This clock rate is achieved using either the internal zero-pin oscillators or an external crystal/resonator connected to X1/X2 pins, and is fully supported across its AEC Q100 qualified temperature range of –40°C to 125°C.

Does the TMS320F28054MPNQ include a programmable control law accelerator (CLA)?

No, the TMS320F28054MPNQ does not include a CLA. Per the official device comparison table, CLA functionality is present only in the TMS320F28055 variant. The TMS320F28054MPNQ relies solely on its 60-MHz C28x CPU for real-time control computations, making it suitable for applications where CLA acceleration is not required but AEC Q100 qualification is essential.

How many analog-to-digital converter (ADC) channels does the TMS320F28054MPNQ support?

The TMS320F28054MPNQ supports 16 ADC input channels across two groups (A and B), with a 12-bit resolution and 3.75 MSPS sampling rate. Its dual sample-and-hold architecture allows simultaneous sampling of up to two channels, and the ADC accepts ratio-metric references (VREFHI/VREFLO) or uses the internal VREFOUT buffered DAC as a stable reference source.

What is the purpose of the VREGENZ pin on the TMS320F28054MPNQ?

The VREGENZ pin (Pin 71) controls the internal voltage regulator: tying it low (to VSS) enables the 1.8-V core supply, allowing single 3.3-V operation; tying it high (to VDDIO) disables the regulator for external 1.8-V supply use. This pin must be hard-wired-not dynamically controlled-as improper states can prevent device boot or cause functional instability in the TMS320F28054MPNQ.

Is the TMS320F28054MPNQ pin-compatible with other devices in the F2805x family?

Yes, the TMS320F28054MPNQ shares the same 80-pin PN LQFP package and pinout with all F2805x variants (e.g., TMS320F28055PN, TMS320F28054PN, TMS320F28052PN). Signal assignments-including GPIO, ePWM, ADC, and JTAG-are identical across the family, enabling hardware reuse and migration between performance tiers while maintaining PCB layout compatibility.
