Product details
Overview
F280033SPZ from Texas Instruments is a C2000™ real-time microcontroller featuring a 120-MHz TMS320C28x DSP core with IEEE 754 FPU, 128KB ECC-protected flash, 69KB ECC-protected RAM, and integrated analog peripherals including three 4-MSPS 12-bit ADCs and 16 ePWM channels (8 with 150-ps high-resolution capability). It targets motor control and power electronics in industrial inverters and EV charging modules.
For engineers reviewing the F280033SPZ datasheet, F280033SPZ pinout, F280033SPZ application, or F280033SPZ equivalent, key selection criteria include its 100-pin LQFP (PZ) package, absence of CLA and Configurable Logic Block (CLB), CAN FD/MCAN interface, FSI up to 200 Mbps, and functional safety support up to ASIL B/SIL 2 in PZ package variants.
Technical Context
The F280033SPZ implements a deterministic real-time control architecture centered on the 120-MHz C28x CPU augmented by TMU, VCRC, and FINTDIV instructions - enabling fast execution of NLPID, trigonometric, and CRC-intensive control loops. Its memory subsystem includes three independent flash banks for concurrent execute-and-program operations and ECC protection across all SRAM blocks.
Peripheral integration is optimized for closed-loop power stage control: dual eQEP modules support CW/CCW encoder feedback; eight SDFM channels enable fast overcurrent detection via comparator filtering; and four CMPSS units with 12-bit DAC references provide hardware-based analog trip zones directly tied to ePWM dead-band logic.

FAQ
What is the maximum operating frequency of the C28x CPU in the F280033SPZ?
The F280033SPZ integrates a TMS320C28x DSP core rated for 120 MHz operation. This frequency is sustained across the full –40°C to 125°C temperature range under recommended operating conditions, with timing closure verified for all on-chip peripherals including ePWM, ADC, and FSI interfaces. The F280033SPZ achieves deterministic real-time performance without dynamic frequency scaling.
Does the F280033SPZ include a Control Law Accelerator (CLA)?
No, the F280033SPZ does not include a Control Law Accelerator (CLA). According to TI's official device comparison table, CLA is explicitly marked as "No" for all F280033 and F280033-Q1 variants. This distinguishes it from higher-tier F28003x parts like F280034SPZ and F280037SPZ, which integrate a 120-MHz CLA for parallel floating-point math execution.
What analog-to-digital converter (ADC) specifications apply to the F280033SPZ?
The F280033SPZ integrates three independent 12-bit ADCs, each capable of 4 MSPS sampling rate with 250 ns conversion time. It supports up to 25 external analog input channels (including two GP-DAC outputs), four post-processing blocks (PPB) per ADC, and hardware windowed comparators (CMPSS) with integrated 12-bit DAC references for real-time trip-zone generation.
Which communication interfaces with isolation capability are supported by the F280033SPZ?
The F280033SPZ supports isolation-ready communication via its Fast Serial Interface (FSI), which provides two differential LVDS lanes (FSITX0/FSIRX0 and FSITX1/FSIRX1) capable of 200 Mbps bidirectional data transfer across galvanic isolation barriers. It also supports isolated CAN FD via external signal transformers on the MCANRX/MCANTX pins.
Is the F280033SPZ qualified for automotive applications?
The standard F280033SPZ is not AEC-Q100 qualified. However, the pin-compatible F280033SPZQ1 variant (with Q1 suffix) is AEC-Q100 Grade 1 qualified (–40°C to 125°C) and certified to ISO 26262 ASIL B and IEC 61508 SIL 2 for functional safety applications. Functional safety documentation and diagnostic coverage data are provided exclusively for Q1 variants.
