Texas Instruments TMX320F28023DAA

Overview

TMS320F28023DAA from Texas Instruments is a 32-bit C28x-core microcontroller optimized for real-time motor and power control, operating at 50 MHz (20-ns cycle time), featuring 8 kB flash, 3 kB SARAM, 8 ePWM channels, 7-channel 12-bit ADC with 500-ns conversion time, and integrated comparators with DACs - deployed in AC-input BLDC motor drives and industrial AC-DC power stages.

For engineers reviewing the TMS320F28023DAA datasheet, TMS320F28023DAA pinout, TMS320F28023DAA application, or TMS320F28023DAA equivalent, key selection criteria include CPU clock speed, on-chip memory size, ePWM channel count, ADC resolution and sampling rate, and thermal grade (–40°C to 105°C).

Technical Context

The TMS320F28023DAA implements a Harvard-architecture C28x CPU with atomic operations and fast interrupt response, supporting deterministic real-time control loops. Its peripheral set includes three 32-bit CPU timers, independent 16-bit timers per ePWM module, and PIE-integrated interrupt handling for all peripherals.

It integrates analog signal conditioning via two analog comparators with internal 10-bit references, directly routable to PWM outputs for hardware-based protection, and a 12-bit ADC with dual sample-and-hold, fixed 0–3.3-V full-scale range, and ratio-metric VREFHI/VREFLO support - enabling closed-loop current/voltage sensing without external op-amps.

FAQ

What is the maximum operating frequency of the TMS320F28023DAA?

The TMS320F28023DAA operates at a maximum CPU frequency of 50 MHz, corresponding to a 20-ns instruction cycle time. This speed is fixed for the '23 variant and is confirmed in the device comparison table of SPRS523P. The TMS320F28023DAA does not support 60-MHz operation like the F28027 or F28026 variants.

Does the TMS320F28023DAA include an integrated voltage regulator?

Yes, the TMS320F28023DAA includes an internal voltage regulator that enables single 3.3-V rail operation for both core and I/O domains. This eliminates external power sequencing requirements and reduces BOM count. The regulator is enabled by default and supports operation across the full –40°C to 105°C temperature range specified for the TMS320F28023DAA.

How many ePWM modules does the TMS320F28023DAA support?

The TMS320F28023DAA supports eight ePWM channels (ePWM1A/B through ePWM4A/B), organized into four modules. Each module contains independent 16-bit time-base counters, compare logic, and trip-zone inputs. This configuration is consistent across all F2802x devices, including the TMS320F28023DAA, and is verified in Table 6-1 of the datasheet.

Is the TMS320F28023DAA pin-compatible with other F2802x DA-package devices?

Yes, the TMS320F28023DAA shares identical pinout and package dimensions (38-pin DA TSSOP) with all other F2802x DA variants, including TMS320F28027DA, TMS320F28026DA, and TMS320F28022DA. Signal assignments, power/ground locations, and JTAG pin positions are fully aligned, enabling hardware reuse across the family where peripheral requirements match.

What analog peripherals are integrated into the TMS320F28023DAA?

The TMS320F28023DAA integrates a 12-bit, 7-channel ADC with 500-ns conversion time and dual sample-and-hold, two analog comparators with integrated 10-bit DACs, an on-chip temperature sensor, and six analog-capable I/O pins (AIO2, AIO4, AIO6, AIO10, AIO12, AIO14). All analog features are present and functional in the TMS320F28023DAA per the F2802x family datasheet.
