Texas Instruments F280023PTSRG4

Overview

TMS320F280023PTSRG4 from Texas Instruments is a real-time microcontroller built on the C28x 32-bit DSP core operating at 100MHz, featuring IEEE 754 FPU, 64KB ECC-protected flash, 24KB RAM (ECC/parity-protected), and 43 GPIOs. It integrates dual 3.45MSPS 12-bit ADCs, 14 ePWM channels (8 with 150ps high-resolution), four CMPSS modules with 12-bit DACs, and supports GaN/SiC-based power electronics control in solar inverters and motor drives.

For engineers reviewing the TMS320F280023PTSRG4 datasheet, TMS320F280023PTSRG4 pinout, TMS320F280023PTSRG4 application, or TMS320F280023PTSRG4 equivalent, key selection criteria include its 48-pin LQFP package, -40°C to 125°C junction temperature rating, CLB-free configuration, and support for fast integer division, TMU, and VCRC instructions in real-time control firmware.

Technical Context

The TMS320F280023PTSRG4 implements a deterministic real-time control architecture centered on the C28x CPU with hardware accelerators: Trigonometric Math Unit (TMU) for sine/cosine/arctan in motor control loops, VCRC engine for CRC-32 computation in communication integrity checks, and Fast Integer Division (FINTDIV) for efficient PID/NLPID execution. Its dual ADC subsystem feeds post-processing blocks (PPBs) directly into ePWM trip zones for cycle-critical protection.

Control peripherals are tightly coupled: 14 ePWM channels include integrated dead-band generation and hardware trip zones (TZs) linked to four windowed comparators (CMPSS); three eCAP modules provide capture timing with one supporting high-resolution capture (HRCAP); two eQEP modules enable CW/CCW encoder feedback. The Fast Serial Interface (FSI) delivers up to 200Mbps isolated communication, while the Host Interface Controller (HIC) enables external host access to internal memory resources.

FAQ

What is the maximum operating frequency of the C28x CPU in the TMS320F280023PTSRG4?

The TMS320F280023PTSRG4 features a C28x 32-bit DSP core running at a maximum frequency of 100MHz. This clock rate is achieved using the on-chip PLL with either internal zero-pin oscillators (two 10MHz INTOSC sources) or an external crystal/clock input. All instruction execution, including FPU, TMU, and VCRC operations, occurs at this deterministic 100MHz rate, ensuring consistent real-time loop timing for power control applications.

Does the TMS320F280023PTSRG4 include Configurable Logic Block (CLB) resources?

No, the TMS320F280023PTSRG4 does not include Configurable Logic Block (CLB) resources. CLB functionality is present only in the 'C' variants (e.g., TMS320F280023CPTSRG4), which integrate two CLB tiles for user-defined logic offload. The standard TMS320F280023PTSRG4 retains full peripheral complement - including 14 ePWM, 3 eCAP, 2 eQEP, dual ADC, and FSI - but omits CLB to optimize cost and die size for applications not requiring FPGA-like logic extension.

How many analog input channels are supported by the TMS320F280023PTSRG4 in its 48-pin LQFP package?

The TMS320F280023PTSRG4 supports 14 external analog input channels in its 48-pin LQFP (PT) package. These are distributed across ADC-A and ADC-C modules, with pins A0–A15 and C0–C15 available for analog use depending on package pin count and multiplexing configuration. The device includes two independent 12-bit, 3.45MSPS ADCs, each capable of sampling up to 14 channels with hardware post-processing blocks (PPBs) for filtering and limit checking before CPU read.

What communication interfaces are integrated into the TMS320F280023PTSRG4?

The TMS320F280023PTSRG4 integrates one CAN bus port, two I²C interfaces, one UART-compatible SCI, two SPI ports, two UART-compatible LIN interfaces, one PMBus interface, and one Fast Serial Interface (FSI) with separate 200Mbps transmitter and receiver paths. These interfaces support robust system-level connectivity for power electronics - including isolated communication (via FSI), automotive diagnostics (CAN/LIN), digital power management (PMBus), and sensor/actuator interfacing (I²C/SPI).

Is the TMS320F280023PTSRG4 qualified for automotive applications?

No, the TMS320F280023PTSRG4 is not AEC-Q100 qualified. It carries the 'S' temperature grade (–40°C to 125°C junction), intended for industrial and commercial applications. For automotive use, TI offers the pin-compatible TMS320F280023QPTSRG4 (Q1 variant), which undergoes AEC-Q100 stress testing and includes additional automotive-specific documentation for functional safety compliance (ISO 26262). Both share identical peripherals, memory, and electrical specs - only qualification and screening differ.
