Texas Instruments F280037SPZ

Overview

F280037SPZ from Texas Instruments is a C28x-based real-time microcontroller with 120-MHz DSP core, IEEE 754 FPU, CLA accelerator, 256KB ECC-protected flash, and 69KB ECC-protected RAM. It integrates three 4-MSPS 12-bit ADCs, 16 ePWM channels (8 with 150-ps resolution), dual CAN/CAN FD interfaces, FSI up to 200Mbps, and CLB for FPGA-like logic extension-designed for motor control in AC inverters and servo drives.

For engineers reviewing the F280037SPZ datasheet, F280037SPZ pinout, F280037SPZ application, or F280037SPZ equivalent, key selection criteria include CLA offload capability, 150-ps HRPWM timing precision, dual CAN FD support, functional safety compliance (ASIL B/SIL 2), and 100-pin LQFP package compatibility with industrial temperature range (–40°C to 125°C).

Technical Context

The F280037SPZ implements a dual-core real-time architecture: the C28x CPU executes deterministic control loops at 120 MHz with FPU, TMU, and VCRC acceleration, while the independent CLA runs parallel floating-point tasks-including NLPID and fast integer division-without CPU intervention. Its memory subsystem features three flash banks enabling concurrent execute-and-program operations.

Analog and control peripherals are tightly coupled: ADC sampling triggers ePWM updates via hardware synchronization, CMPSS comparators feed directly into trip zones, and SDFM filters process sigma-delta sensor data with comparator-triggered fast-action response. The 100-pin PZ package exposes all 55 GPIO, 23 analog inputs, and full peripheral pinout including FSI TX/RX, MCAN, DCAN, and dual LIN/SCI.

FAQ

What is the maximum operating junction temperature for F280037SPZ?

The F280037SPZ has a specified junction temperature range of –40°C to 150°C. This rating applies to the 100-pin PZ package and enables operation in demanding environments such as industrial motor drives and automotive under-hood applications. Thermal design must ensure sustained TJ ≤ 150°C under worst-case load and ambient conditions.

Does F280037SPZ support functional safety certification out of the box?

Yes, the F280037SPZ in the PZ package is ISO 26262 ASIL B and IEC 61508 SIL 2 certified by TÜV SÜD. It includes hardware safety mechanisms such as dual-clock comparator (DCC), memory built-in self-test (HWBIST), power-on self-test (MPOST), and ERAD debug trace-enabling systematic development of safety-critical motor control systems.

How many ePWM channels on F280037SPZ support high-resolution mode?

The F280037SPZ provides eight ePWM channels (ePWM1–ePWM4, each with A/B outputs) capable of 150-ps resolution. This high-resolution capability is essential for precise timing control in GaN and SiC-based power stages, enabling accurate dead-time insertion and reduced switching losses in high-frequency converters.

Is F280037SPZ pin-compatible with other TMS320F28003x variants in the PZ package?

Yes, all TMS320F28003x devices in the 100-pin PZ package-including F280039C, F280037C, and F280037SPZ-share identical pinout and electrical characteristics. This allows hardware reuse across performance tiers while scaling flash, CLA, and CLB features in firmware.

What communication interfaces does F280037SPZ provide for isolated gate driver control?

The F280037SPZ includes Fast Serial Interface (FSI) with one transmitter and one receiver supporting up to 200Mbps, designed explicitly for robust isolated communication with gate drivers. It also supports SPI and SCI with configurable GPIO remapping-enabling flexible interface selection based on isolation barrier requirements and bandwidth needs.
