Product details
Overview
F280039SPM from Texas Instruments is a C2000™ real-time microcontroller featuring a 120-MHz TMS320C28x DSP core with IEEE 754 FPU, 384KB ECC-protected flash across three banks, 69KB ECC-protected RAM, and dual 10-MHz internal oscillators. It integrates 16 ePWM channels (8 with 150-ps high-resolution), three 4-MSPS 12-bit ADCs, and supports GaN/SiC power stage control in motor drives and digital power systems.
For engineers reviewing the F280039SPM datasheet, F280039SPM pinout, F280039SPM application, or F280039SPM equivalent, key selection considerations include CLA-accelerated real-time control, functional safety compliance (ASIL B/SIL 2), CAN FD + DCAN dual-bus support, and 100-pin LQFP package with 51 GPIOs and 25 ADC channels.
Technical Context
The F280039SPM implements a dual-core real-time architecture: the main C28x CPU executes at 120 MHz with FPU, TMU, and VCRC extensions for fast trigonometric and CRC operations, while the independent CLA runs at 120 MHz executing floating-point control law code without CPU intervention. Both cores share access to on-chip memory and peripherals via dedicated message RAM and XBAR routing.
Its analog subsystem tightly couples three 4-MSPS ADCs with four CMPSS modules (each with 12-bit DAC references) and two buffered DAC outputs, enabling closed-loop current/voltage sensing and fast overvoltage protection. The control peripheral set includes eCAP/HRCAP, eQEP, SDFM, and EPG - all synchronized to ePWM timers for deterministic timing in power electronics feedback loops.

FAQ
What is the maximum operating frequency of the C28x CPU in the F280039SPM?
The C28x CPU in the F280039SPM operates at a maximum frequency of 120 MHz. This clock rate is generated by the on-chip PLL using either an external crystal (1–20 MHz) or internal 10-MHz oscillator. All instruction execution, including FPU, TMU, and VCRC operations, occurs at this frequency, enabling deterministic real-time control loops with sub-microsecond latency. The F280039SPM datasheet confirms 120 MHz as the rated maximum under specified voltage and temperature conditions.
Does the F280039SPM support functional safety certification for automotive applications?
Yes, the F280039SPM is qualified for functional safety applications with ISO 26262 ASIL B and IEC 61508 SIL 2 certification by TÜV SÜD. This applies to the PZ (100-pin LQFP) and Q100 PM packages. The device includes hardware features such as memory built-in self-test (HWBIST), memory power-on self-test (MPOST), embedded real-time analysis and diagnostics (ERAD), and dual-zone security - all documented to support systematic and hardware safety requirements in automotive motor control and battery systems.
How many independent ADC modules does the F280039SPM integrate, and what is their sampling rate?
The F280039SPM integrates three independent 12-bit Analog-to-Digital Converters (ADCs), each capable of 4 million samples per second (4 MSPS). These ADCs support up to 25 external single-ended input channels (including two gpdac outputs) and feature four post-processing blocks (PPBs) per ADC for real-time filtering, averaging, and oversampling. The F280039SPM datasheet specifies 250 ns conversion time and tight synchronization with ePWM timers for precise current/voltage sampling in power stage feedback loops.
What communication interfaces with CAN capability does the F280039SPM provide?
The F280039SPM provides two independent CAN interfaces: one DCAN (Controller Area Network) module compliant with CAN 2.0B protocol, and one MCAN (CAN FD) module supporting CAN with Flexible Data-Rate up to 5 Mbps. Both interfaces operate simultaneously and are electrically isolated from each other. The F280039SPM pinout assigns dedicated differential pairs (CANA_H/L and CANFD_H/L) and supports full mailbox-based message handling, error counters, and automatic retransmission - essential for automotive and industrial networked control systems.
Is the F280039SPM pin-compatible with other members of the TMS320F28003x family?
Yes, the F280039SPM in the 100-pin PZ package shares identical pinout and electrical characteristics with other 100-pin variants including TMS320F280039C, TMS320F280039C-Q1, and TMS320F280039-Q1. This allows direct PCB reuse across commercial and automotive-qualified versions. However, pin compatibility does not extend to smaller packages (PN, PM, PT) or devices with different flash sizes (e.g., F280037C), as peripheral mapping and GPIO availability differ significantly between package options.
