Texas Instruments F280023PTQR

Overview

F280023PTQR from Texas Instruments is a C28x-based real-time microcontroller designed for high-efficiency power electronics control, featuring a 100MHz 32-bit DSP core with IEEE 754 FPU, 64KB ECC-protected flash, 24KB RAM (ECC/parity-protected), and 20 GPIO pins in a 48-pin LQFP package. It targets solar inverters, EV charging power modules, and industrial motor drives requiring deterministic timing and analog integration.

For engineers reviewing the F280023PTQR datasheet, F280023PTQR pinout, F280023PTQR application, or F280023PTQR equivalent, key selection criteria include its 14-channel ePWM (8 with 150ps resolution), dual 3.45MSPS 12-bit ADCs with four post-processing blocks, integrated CLB for custom logic, and AEC-Q100 qualification for automotive-grade reliability in powertrain and on-board charger designs.

Technical Context

The F280023PTQR implements a deterministic real-time control architecture centered on the C28x CPU with TMU and VCRC acceleration for fast trigonometric and CRC operations. Its analog subsystem tightly couples two 12-bit ADCs (3.45MSPS) and four windowed comparators (CMPSS) with internal 12-bit DACs to enable closed-loop current/voltage sensing in GaN/SiC-based power stages.

Control peripherals include 14 ePWM channels (8 high-resolution), three eCAP modules (one with HRCAP), two eQEP interfaces, and a Configurable Logic Block (CLB) supporting position manager functions. Communication is handled via one CAN, two SPI, one SCI, two LIN, two I2C, one PMBus, and one FSI (200Mbps) interface - all accessible through pin multiplexing on its 48-pin LQFP footprint.

FAQ

What is the maximum operating frequency of the C28x core in F280023PTQR?

The F280023PTQR features a C28x 32-bit DSP core running at 100MHz, delivering deterministic real-time performance for floating- and fixed-point control algorithms. This clock speed is maintained across its full operating temperature range (–40°C to 125°C) and supports IEEE 754-compliant FPU operations, TMU-accelerated trigonometric functions, and VCRC instructions - all critical for high-speed current loop execution in F280023PTQR-based power converters.

Does F280023PTQR support AEC-Q100 qualification for automotive use?

Yes, F280023PTQR is AEC-Q100 qualified for Grade 1 (–40°C to 125°C free-air temperature), making it suitable for automotive applications including on-board chargers, DC/DC converters, and electric power steering modules. Its functional safety features - such as hardware BIST, memory POST, windowed watchdog, and dual-clock comparator - align with ISO 26262 ASIL-B system design requirements, as documented in TI's F280023PTQR safety manual.

How many analog-to-digital converter (ADC) channels does F280023PTQR support?

F280023PTQR integrates two independent 12-bit ADCs capable of 3.45MSPS sampling, with up to 14 external single-ended input channels in its 48-pin PT package. Each ADC includes four post-processing blocks (PPBs) for real-time result filtering, offset correction, and window comparison - enabling simultaneous voltage/current sensing and fast over-limit detection without CPU intervention in F280023PTQR-based motor control or power supply designs.

What communication interfaces are available on F280023PTQR?

F280023PTQR provides one CAN bus port, two SPI ports, one UART-compatible SCI, two LIN interfaces, two I2C interfaces, one PMBus interface, and one Fast Serial Interface (FSI) with 200Mbps capability. These interfaces are implemented via pin multiplexing on its 20 GPIOs, allowing flexible system connectivity - for example, CAN for vehicle network integration, FSI for isolated gate driver communication, and PMBus for digital power management in F280023PTQR-based applications.

Is the Configurable Logic Block (CLB) present in F280023PTQR?

No, the F280023PTQR does not include the Configurable Logic Block (CLB). The CLB is only available in the 'C' variants (e.g., F280023CPTQR), which feature two CLB tiles for implementing custom logic, position manager functions, or safety monitors in hardware. F280023PTQR retains the full complement of control peripherals (14 ePWM, 3 eCAP, 2 eQEP) and analog resources but relies solely on the C28x CPU and accelerators (TMU, VCRC) for real-time computation - a deliberate trade-off for cost-sensitive, non-CLB-dependent applications.
