Texas Instruments TMS320F28023DAQ

Overview

TMS320F28023DAQ 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, 32-bit CPU timers, ePWM with HRPWM, 12-bit ADC (7-channel, 2 MSPS), and integrated comparators. It targets compact inverter power stages and BLDC motor drives requiring deterministic timing and analog integration.

For engineers reviewing the TMS320F28023DAQ datasheet, TMS320F28023DAQ pinout, TMS320F28023DAQ application, or TMS320F28023DAQ equivalent, key selection criteria include its 38-pin TSSOP package, single 3.3-V supply operation, on-chip VREG, 20 GPIO pins, and AEC-Q100 qualified temperature range (–40°C to 125°C).

Technical Context

The TMS320F28023DAQ implements the C28x CPU core with Harvard bus architecture, atomic operations, and unified memory model-enabling efficient C/C++ execution in closed-loop control. Its peripheral set includes four ePWM modules (each with independent 16-bit timer and high-resolution extension), one eCAP input, and dual-sample-and-hold ADC supporting ratio-metric VREFHI/VREFLO references.

System-level timing is managed via dual zero-pin oscillators, on-chip crystal oscillator support (X1/X2), missing-clock detection, and watchdog timer. The device uses an internal voltage regulator for single-rail 3.3-V operation and supports JTAG debugging with TRST/TCK/TMS/TDI/TDO signals multiplexed on GPIO pins 35–38.

FAQ

What is the maximum operating frequency of the TMS320F28023DAQ?

The TMS320F28023DAQ 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 confirmed in the device comparison table; it does not support 60 MHz operation like the F28027 or F28026 variants.

Does the TMS320F28023DAQ include an on-chip voltage regulator?

Yes, the TMS320F28023DAQ integrates an internal voltage regulator (VREG) enabling single 3.3-V supply operation. This eliminates external LDO requirements and simplifies power design-confirmed in the "Low cost for both device and system" feature list and functional block diagram.

How many ADC channels does the TMS320F28023DAQ support?

The TMS320F28023DAQ supports 7 analog input channels (ADCINA0–ADCINA6) for Group A ADC conversion. This is explicitly stated in Table 6-1 (Device Comparison) and matches the pin diagram showing only seven Group A analog inputs on the 38-pin DA package.

Is the TMS320F28023DAQ pin-compatible with other F2802x devices in the DA package?

Yes, all F2802x devices in the 38-pin DA TSSOP package-including TMS320F28027DA, TMS320F28026DA, TMS320F28023DAQ, TMS320F28022DAQ, and TMS320F28021DAQ-share identical pinouts and mechanical dimensions, enabling drop-in replacement within the same package family.

What communication interfaces are available on the TMS320F28023DAQ?

The TMS320F28023DAQ includes one Serial Communications Interface (SCI/UART), one Serial Peripheral Interface (SPI), and one Inter-Integrated Circuit (I2C) module-all confirmed in the "Serial port peripherals" feature list and functional block diagram; no CAN or USB interfaces are present.
