Product details
Overview
TMS320F28054MPNT from Texas Instruments is a 60-MHz C28x-core real-time microcontroller with integrated CLA accelerator, 64 KB flash, 10 KB SARAM, 14 ePWM channels, and analog front-end including 12-bit ADC (3.75 MSPS), 7 comparators, 4 PGAs, and 3 DACs - deployed in motor control, inverter systems, and AC/DC drive modules.
For engineers reviewing the TMS320F28054MPNT datasheet, TMS320F28054MPNT pinout, TMS320F28054MPNT application, or TMS320F28054MPNT equivalent, key selection criteria include CPU+CLA dual-execution capability, on-chip analog integration for sensorless FOC, 80-pin LQFP package compatibility, and AEC-Q100-qualified temperature range (–40°C to 125°C).
Technical Context
The TMS320F28054MPNT implements a Harvard-architecture C28x CPU with atomic instruction support and unified memory mapping, paired with a dedicated 32-bit floating-point CLA that executes control law code independently of the main CPU - enabling deterministic sub-microsecond loop closure in motor control.
Its analog subsystem integrates dual-sample-and-hold ADC with 16-channel input multiplexing, seven rail-to-rail comparators (three with internal 6-bit DAC references), four programmable-gain amplifiers (gain ≈ 3/6/11), and one buffered reference DAC - all directly routable to ePWM trip zones for hardware-based protection and fast-loop response.

Equivalent & Alternatives
The following parts are listed as comparable options for similar real-time motor control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMS320F28054PN | Same core, peripherals, and pinout; differs only in temperature grade (–40°C to 105°C vs. –40°C to 125°C) and AEC-Q100 qualification | Not qualified for automotive underhood use; suitable for industrial drives where ambient temperature remains ≤105°C | Select when AEC-Q100 compliance is not required and cost optimization is prioritized. |

Yes, the TMS320F28054MPNT includes four programmable gain amplifiers (PGAs) with discrete gain settings of approximately 3, 6, or 11. These PGAs are part of the integrated analog front end and connect directly to ADC input channels and comparator inputs - enabling high-accuracy current sensing without external op-amp circuitry. All four PGAs are fully functional and documented in the device comparison table for the F28054 family.

What analog-to-digital converter (ADC) specifications does the TMS320F28054MPNT support?
The TMS320F28054MPNT features a 12-bit ADC with 3.75 MSPS sampling rate, 267-ns conversion time, and 16 input channels organized in two groups (A and B). It supports dual sample-and-hold, ratio-metric referencing (VREFHI/VREFLO), and fixed full-scale range of 0–3.3 V. These specifications are confirmed in the Device Comparison table and apply identically to the TMS320F28054MPNT variant.
Does the TMS320F28054MPNT support AEC-Q100 qualification and what grade is it rated for?
Yes, the TMS320F28054MPNT is AEC-Q100 qualified for automotive applications and rated as Grade 1, supporting operation from –40°C to 125°C. This qualification is explicitly stated in the Device Comparison table under "Temperature options" for the "28054-Q1" variant, and the "MPNT" suffix denotes the Q1 automotive-grade packaging and screening - distinguishing it from commercial-grade "PN" variants.
