Product details
Overview
TMS320F28022PTQ from Texas Instruments is a C2000™ 32-bit real-time control microcontroller optimized for motor and digital power applications. It features a 50-MHz C28x CPU, 16 KB on-chip Flash, 3 KB SARAM, 8 ePWM channels with 4 high-resolution outputs, 12-bit ADC (7-channel, 500-ns conversion), and integrated comparators with DACs - deployed in industrial AC-DC converters and BLDC motor drives.
For engineers reviewing the TMS320F28022PTQ datasheet, TMS320F28022PTQ pinout, TMS320F28022PTQ application, or TMS320F28022PTQ equivalent, key selection criteria include its AEC-Q100 qualified Q-grade temperature range (–40°C to 125°C), LQFP-48 package, single 3.3-V supply operation, and HRPWM dual-edge modulation capability for precision timing control in safety-critical automotive and industrial systems.
Technical Context
The TMS320F28022PTQ implements a Harvard-architecture C28x core with atomic operations and fast interrupt response, enabling deterministic real-time control loops. Its peripheral set includes three 32-bit CPU timers, PIE-integrated interrupt handling, and dedicated ePWM modules with TZ fault protection and EPWMSYNCI/O for synchronized multi-phase switching.
On-chip analog integration comprises a 12-bit ADC with dual sample-and-hold, internal VREFHI/VREFLO ratio-metric reference support, and two analog comparators with programmable 10-bit DAC references - all directly routable to PWM trip zones for hardware-based overcurrent and overvoltage protection without CPU intervention.

FAQ
What is the maximum operating frequency of the TMS320F28022PTQ?
The TMS320F28022PTQ operates at a maximum CPU frequency of 50 MHz, corresponding to a 20-ns instruction cycle time. This speed is factory-configured and supported across its full temperature range (–40°C to 125°C). The device uses an internal PLL to derive SYSCLK from either the on-chip zero-pin oscillator or an external crystal/resonator, with clock stability verified per AEC-Q100 Grade Q requirements. All timing specifications in the TMS320F28022PTQ datasheet assume this 50-MHz operation.
Does the TMS320F28022PTQ support hardware-based overcurrent protection?
Yes, the TMS320F28022PTQ supports hardware-based overcurrent protection through its two integrated analog comparators with programmable 10-bit DAC references. Comparator outputs (COMP1OUT/COMP2OUT) can be directly routed to ePWM trip-zone (TZ) inputs (TZ1–TZ3), triggering immediate PWM shutdown within one system clock cycle - bypassing CPU interrupt latency. This capability is confirmed in the TMS320F28022PTQ Technical Reference Manual Section 9.9.4 and is used in production BLDC drives for sub-1-μs fault response.
What serial communication interfaces are available on the TMS320F28022PTQ?
The TMS320F28022PTQ integrates one Serial Communications Interface (SCI) compatible with UART, one Serial Peripheral Interface (SPI), and one Inter-Integrated Circuit (I²C) module. These are implemented as dedicated peripherals - not bit-banged GPIO - and share pins with general-purpose I/O (e.g., SCITXDA/SCIRXDA on GPIO12/GPIO28). Each includes 4-level FIFOs and independent clock dividers, enabling concurrent communication with external sensors, gate drivers, or host controllers without CPU polling overhead.
Is the TMS320F28022PTQ pin-compatible with other F2802x devices in LQFP-48 packaging?
Yes, the TMS320F28022PTQ is pin-compatible with all F2802x family members offered in the PT (LQFP-48) package, including TMS320F28023PTQ, TMS320F28026PTQ, and TMS320F28027PTQ. Pin assignments, power domains, JTAG interface, and peripheral signal mappings match exactly per TI's SPRS523P datasheet Figure 7-1 and Table 6-1. This allows direct PCB reuse across performance tiers while maintaining identical layout, decoupling, and signal integrity design.
What is the Flash memory capacity and endurance rating of the TMS320F28022PTQ?
The TMS320F28022PTQ contains 16 KB of on-chip Flash memory organized as 16-bit words. TI specifies 10,000 write/erase cycles minimum and 10-year data retention at 125°C per the SPRS523P datasheet Section 8.6. Flash is secured via the 128-bit code-security module, and programming is performed in-sector blocks using the on-chip Flash API - validated for use in field firmware updates of motor control applications without external programmers.
