Product details
Overview
TMS320F28023DAT from Texas Instruments is a 32-bit C28x-core microcontroller optimized for real-time motor control and digital power applications, operating at 50 MHz (20-ns cycle time), featuring 8 kB flash, 3 kB SARAM, 3-channel 12-bit ADC (3 MSPS), 8 ePWM channels with HRPWM support, and integrated comparators. It targets compact inverter designs requiring deterministic timing and analog integration.
For engineers reviewing the TMS320F28023DAT datasheet, TMS320F28023DAT pinout, TMS320F28023DAT application, or TMS320F28023DAT equivalent, key selection considerations include its 38-pin TSSOP package, single 3.3-V supply operation, 50-MHz CPU performance, on-chip VREG, and compatibility with C2000™ real-time control ecosystem tools and firmware libraries.
Technical Context
The TMS320F28023DAT implements the TMS320C28x 32-bit CPU core with Harvard architecture, atomic instructions, and unified memory model-enabling efficient C/C++ execution in closed-loop control. Its peripheral set includes three 32-bit CPU timers, PIE interrupt controller, and dual-sample-and-hold ADC for synchronized sampling.
It integrates enhanced control peripherals: eight ePWM modules (each with independent 16-bit timer and HRPWM capability), two analog comparators with internal 10-bit references, and configurable GPIO with input filtering. Clocking relies on dual zero-pin oscillators or external crystal/XCLKIN, with missing-clock detection and watchdog timer support.

FAQ
What is the maximum operating frequency of the TMS320F28023DAT?
The TMS320F28023DAT operates at a maximum CPU frequency of 50 MHz, corresponding to a 20-ns instruction cycle time. This speed is fixed for the -DAT variant per TI's device comparison table and is achieved using the internal 1.8-V VREG powered from a single 3.3-V supply. The 50-MHz rating ensures deterministic execution for real-time control loops up to 20 kHz in typical motor drive implementations.
Does the TMS320F28023DAT support CAN communication?
No, the TMS320F28023DAT does not include a Controller Area Network (CAN) peripheral. Its serial interfaces are limited to one SCI (UART-compatible), one SPI, and one I²C module - all confirmed in the device comparison table and functional block diagram. For CAN-enabled variants in the F2802x family, engineers must select higher-pin-count devices such as the TMS320F2803x series.
How many analog-to-digital converter (ADC) channels does the TMS320F28023DAT have?
The TMS320F28023DAT features a 12-bit ADC with 7 input channels in Group A (ADCINA0–ADCINA6), as specified in the device comparison table and signal descriptions. It does not include Group B ADC channels (ADCINB1–ADCINB7), which are only available on 48-pin variants like the TMS320F28023PT. The ADC supports 3 MSPS sampling rate and dual sample-and-hold for synchronized acquisition.
What is the purpose of the VREGENZ pin on the TMS320F28023DAT?
The VREGENZ pin on the TMS320F28023DAT is an active-low enable input for the internal voltage regulator (VREG). When pulled low, it activates the 1.8-V core supply derived from the 3.3-V VDDIO rail. This pin must be externally tied to GND for normal operation; leaving it floating or pulling high disables the VREG and halts device functionality. Its behavior is documented in Section 9.5 of the datasheet.
Is the TMS320F28023DAT pin-compatible with other F2802x devices in the DA package?
Yes, the TMS320F28023DAT is fully pin-compatible with other 38-pin DA TSSOP variants in the F2802x family (e.g., TMS320F28026DAT, TMS320F28027DAT), sharing identical pin assignments, electrical characteristics, and package dimensions. This allows direct substitution within the same PCB footprint when upgrading flash size, CPU speed, or peripheral count - provided firmware and configuration align with the target device's specifications.
