Product details
Overview
TMS320F28023PTQ from Texas Instruments is a C28x-core 32-bit real-time control microcontroller operating at 50 MHz (20-ns cycle time), featuring 8 kB flash, 3 kB SARAM, 12-bit ADC with 7 channels, 8 ePWM channels, and integrated comparators - deployed in motor drive power stages and industrial AC-DC converters.
For engineers reviewing the TMS320F28023PTQ datasheet, TMS320F28023PTQ pinout, TMS320F28023PTQ application, or TMS320F28023PTQ equivalent, key selection criteria include its AEC-Q100 qualified automotive temperature range (–40°C to 125°C), LQFP-48 package, single 3.3-V supply operation, and HRPWM-capable ePWM peripheral for high-fidelity digital power control.
Technical Context
The TMS320F28023PTQ implements the TMS320C28x CPU core with Harvard bus architecture, atomic operations, and unified memory model - enabling deterministic real-time interrupt response and efficient C/C++ code execution. It integrates a Peripheral Interrupt Expansion (PIE) block supporting all peripheral interrupts and three independent 32-bit CPU timers for precise system timing coordination.
Its analog subsystem includes dual analog comparators with internal 10-bit references, routed directly to ePWM trip-zone logic, and a 12-bit ADC with 7 input channels, 3-MSPS sampling rate, and dual sample-and-hold - optimized for closed-loop current/voltage sensing in motor and power conversion systems.

FAQ
What is the maximum operating frequency of the TMS320F28023PTQ?
The TMS320F28023PTQ operates at a maximum CPU frequency of 50 MHz, corresponding to a 20-ns instruction cycle time. This speed is fixed for the TMS320F28023 variant and is confirmed in the Device Comparison table (Table 6-1) of the SPRS523P datasheet. The TMS320F28023PTQ does not support 60-MHz operation - that capability is reserved for the TMS320F28027 and TMS320F28026 variants.
Does the TMS320F28023PTQ include an integrated temperature sensor?
Yes, the TMS320F28023PTQ includes an on-chip temperature sensor as explicitly listed in the Features section and Device Comparison table. It provides die temperature monitoring without external components and is accessible via dedicated ADC channel ADCINA7, enabling thermal management in motor drives and power converters.
How many ADC channels are available on the TMS320F28023PTQ?
The TMS320F28023PTQ features 7 ADC input channels (ADCINA0–ADCINA6), all belonging to Group A. The Device Comparison table confirms "7" under "Channels" for the 12-Bit ADC row for TMS320F28023. Group B inputs (ADCINBx) are not implemented on this variant, distinguishing it from higher-memory F28026/F28027 devices.
Is the TMS320F28023PTQ pin-compatible with other F2802x devices in LQFP-48 package?
Yes, the TMS320F28023PTQ shares identical pinout and package (LQFP-48, PT suffix) with TMS320F28026PTQ, TMS320F28027PT, and other PT-suffixed F2802x devices. Pin Diagram Figure 7-1 applies universally across the family, and signal descriptions in Section 7.2.1 confirm consistent terminal mapping - enabling hardware reuse across performance tiers.
What serial communication interfaces are integrated into the TMS320F28023PTQ?
The TMS320F28023PTQ integrates one Serial Communications Interface (SCI/UART), one Serial Peripheral Interface (SPI), and one Inter-Integrated Circuit (I²C) module - as verified in the Features list and Device Comparison table. All three are present and functional in the LQFP-48 package, with dedicated pins (e.g., SCITXDA/SCIRXDA, SPISIMOA/SPISOMIA/SPISTEA, SDAA/SCLA) assigned in Figure 7-1.
