Product details
Overview
TMS320F28023DAS 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.
For engineers reviewing the TMS320F28023DAS datasheet, TMS320F28023DAS pinout, TMS320F28023DAS application, or TMS320F28023DAS equivalent, key selection criteria include its 38-pin TSSOP package, single 3.3-V supply operation, on-chip VREG, temperature range (–40°C to 125°C), and support for closed-loop control via ePWM/HRPWM/ADC/comparator integration.
Technical Context
The TMS320F28023DAS implements the C28x CPU core with Harvard bus architecture, atomic operations, and unified memory model-enabling deterministic real-time execution. Its peripheral set centers on high-resolution timing control: four ePWM modules (each with independent 16-bit timer and dual-edge HRPWM capability), one eCAP input, and a 12-bit ADC with dual sample-and-hold and ratio-metric reference support.
Clocking relies on internal zero-pin oscillators or external crystal/XCLKIN, with integrated POR/BOR and watchdog timer. The device uses an on-chip voltage regulator for single-rail 3.3-V operation and supports JTAG debugging via dedicated pins multiplexed with GPIO functions including TRST, TCK, TMS, TDI, and TDO.

Equivalent & Alternatives
The following parts are listed as comparable options for similar real-time control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMS320F28023PT | 48-pin LQFP package; adds two ADC channels (13 vs. 7), COMP2, SPI, I2C, SCI, and 2 additional GPIOs | Suitable for designs needing expanded analog I/O, serial communication, or higher pin count for complex sensor interfacing | Select when board layout allows larger footprint and application requires extra peripherals not present on DA variant |
| TMS320F28022DA | Same 38-pin TSSOP package but with 40 MHz CPU (25-ns cycle time), 4 kB flash, 2 kB SARAM, and no HRPWM | Targeted at cost-sensitive, lower-performance motor control where sub-100-ns PWM resolution is unnecessary | Choose for simpler scalar V/f drives or basic fan control where reduced memory and timing capability are acceptable |
Compared with TMS320F28023PT, the TMS320F28023DAS offers identical core functionality in a smaller footprint but trades off ADC channel count and serial interfaces; versus TMS320F28022DA, it delivers higher CPU speed, more memory, and critical HRPWM for advanced motor control.

FAQ
What is the maximum operating frequency of the TMS320F28023DAS?
The TMS320F28023DAS operates at a maximum CPU frequency of 50 MHz, corresponding to a 20-ns instruction cycle time. This speed is fixed for the DAS variant and is confirmed in TI's SPRS523P datasheet revision P. The device does not support overclocking, and system timing-including ePWM, ADC, and peripheral clocks-is derived from this base frequency via configurable dividers.
Does the TMS320F28023DAS include an integrated voltage regulator?
Yes, the TMS320F28023DAS includes an on-chip voltage regulator (VREG) that generates the internal 1.8-V core supply from a single 3.3-V input. This eliminates the need for an external 1.8-V rail, simplifying power design and reducing bill-of-materials cost. The VREG is enabled by default at power-up and supports operation across the full –40°C to +125°C temperature range specified for the TMS320F28023DAS.
How many high-resolution PWM channels does the TMS320F28023DAS support?
The TMS320F28023DAS supports four high-resolution PWM (HRPWM) channels-specifically ePWM1A, ePWM2A, ePWM3A, and ePWM4A-as confirmed in Table 6-1 of the SPRS523P datasheet. Each HRPWM channel enables dual-edge control with sub-nanosecond resolution, critical for minimizing dead-time uncertainty in SiC and GaN-based motor drives and digital power converters.
What analog-to-digital converter (ADC) specifications apply to the TMS320F28023DAS?
The TMS320F28023DAS integrates a 12-bit ADC with 7 input channels (Group A only), 2-MSPS conversion rate, and dual sample-and-hold capability. It supports ratio-metric referencing using VREFHI/VREFLO and includes an on-chip temperature sensor. Unlike higher-pin-count variants, it does not include Group B ADC channels or COMP2, as verified in the Device Comparison table of SPRS523P.
Is the TMS320F28023DAS pin-compatible with other F2802x family members in the same package?
Yes, the TMS320F28023DAS shares identical pinout and electrical characteristics with other 38-pin DA TSSOP variants in the F2802x family-including TMS320F28022DA, TMS320F28021DA, and TMS320F28020DA-as documented in Figure 7-2 of SPRS523P. This allows direct substitution within the same package footprint when memory, CPU speed, or peripheral requirements align.
