Product details
Overview
TMS320F28022DAT 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 16 KB on-chip Flash, 3 KB SARAM, 8-channel ePWM with 4 high-resolution outputs, 12-bit ADC (3 MSPS, 7 channels), and integrated comparators with DACs - deployed in AC-input BLDC motor drives and industrial AC-DC power stages.
For engineers reviewing the TMS320F28022DAT datasheet, TMS320F28022DAT pinout, TMS320F28022DAT application, or TMS320F28022DAT equivalent, key selection criteria include CPU clock speed (50 MHz), Flash/SARAM memory allocation, HRPWM channel count, ADC resolution and sampling rate, and TSSOP-38 package compatibility with space-constrained control boards.
Technical Context
The TMS320F28022DAT 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, PIE-integrated interrupt handling, and dual-sample-and-hold ADC architecture enabling synchronized current/voltage sampling.
Control-specific peripherals are tightly coupled: ePWM modules support dead-time insertion and trip-zone protection; HRPWM enables dual-edge modulation for precise timing; analog comparators route directly to PWM outputs for hardware-based fault response; and the internal 1.8-V regulator enables single 3.3-V rail operation without sequencing.

FAQ
What is the maximum operating frequency of the TMS320F28022DAT?
The TMS320F28022DAT operates at a maximum CPU clock frequency of 50 MHz, corresponding to a 20-ns instruction cycle time. This speed is factory-configured and supported across its full industrial temperature range (–40°C to 105°C). The device uses an internal PLL to derive SYSCLK from either the on-chip oscillator or external crystal, and this 50-MHz rating is validated per TI's SPRS523P datasheet specifications for the TMS320F28022DAT variant.
Does the TMS320F28022DAT support hardware-based fault protection?
Yes, the TMS320F28022DAT provides hardware-trip capability through its ePWM trip-zone (TZ) inputs and integrated analog comparators. COMP1OUT and COMP2OUT can be routed directly to EPWM trip inputs, enabling sub-microsecond shutdown of PWM outputs upon overcurrent or overvoltage detection - without CPU intervention. This functionality is fully implemented in the TMS320F28022DAT's silicon and documented in Section 9.9.4 of the technical reference manual.
How much Flash and RAM does the TMS320F28022DAT include?
The TMS320F28022DAT integrates 16 KB of on-chip Flash memory (16-bit words) for program storage and 3 KB of SARAM (single-access RAM) operating at zero wait states. These memory resources are fixed for this specific part number and confirmed in Table 6-1 of the SPRS523P datasheet. No configuration or option bits alter these values - they are hard-coded silicon features of the TMS320F28022DAT.
Is the TMS320F28022DAT pin-compatible with other F2802x devices in TSSOP-38?
Yes, the TMS320F28022DAT shares identical pinout, electrical characteristics, and package dimensions with all other F2802x variants offered in the 38-pin DA TSSOP package - including TMS320F28021DAT, TMS320F28023DAT, and TMS320F28026DAT. Pin assignments, signal multiplexing, and power/ground locations are fully aligned per Figure 7-2 in the datasheet, enabling direct PCB reuse across this subset.
What communication interfaces are available on the TMS320F28022DAT?
The TMS320F28022DAT includes one Serial Communications Interface (SCI) configured as UART, one Serial Peripheral Interface (SPI), and one Inter-Integrated Circuit (I²C) module. All three are functional in the TSSOP-38 package: SCI uses GPIO12/SCITXDA and GPIO28/SCIRXDA; SPI uses GPIO16–19; I²C uses GPIO28/SDAA and GPIO29/SCLA. These interfaces are silicon-verified and enabled by default peripheral clock gating in the device's system control module.
