Product details
Overview
F280037CSPN 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, and FSI up to 200Mbps - optimized for motor control in AC inverters, servo drives, and EV power stages.
For engineers reviewing the F280037CSPN datasheet, F280037CSPN pinout, F280037CSPN application, or F280037CSPN equivalent, key selection criteria include CLA-enabled deterministic control loop execution, functional safety support (ASIL B/SIL 2), 80-pin LQFP package thermal performance, and live firmware update capability for minimal downtime during field updates.
Technical Context
The F280037CSPN implements a dual-core real-time architecture: the main C28x CPU runs at 120 MHz with FPU, TMU, and VCRC extensions for fast trigonometric and CRC-intensive control math; the independent CLA executes floating-point control law code concurrently at 120 MHz with dedicated message RAM and peripheral access.
Its analog subsystem tightly couples three 12-bit ADCs (4 MSPS, 250-ns conversion time) with four CMPSS modules (12-bit internal DAC references) and two buffered DAC outputs, enabling closed-loop current/voltage sensing and fast comparator-triggered protection in power stage feedback paths.

Equivalent & Alternatives
The following parts are listed as comparable options for similar real-time control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMS320F280039C | 384KB flash (vs. 256KB), same CLA/CLB/peripheral set, identical 80-pin PN package | Supports larger control algorithms and dual-bank firmware storage; no change in real-time latency or analog performance | Select when firmware size exceeds 256KB or when future-proofing for feature expansion is required |
| TMS320F280034 | No CLA or CLB; 128KB flash; reduced ePWM count (12 channels); no CAN FD or FSI | Limited to cost-sensitive, lower-performance motor control where deterministic sub-µs loop timing is not required | Select only for non-safety-critical, low-feature-count applications where BOM cost reduction outweighs real-time capability loss |
Compared with TMS320F280039C, F280037CSPN trades flash capacity for identical real-time control capability and package compatibility; compared with F280034, it delivers full CLA/CLB acceleration, CAN FD, and FSI - essential for next-generation GaN/SiC power systems requiring hardware-enforced safety and high-speed isolation.

FAQ
What is the maximum operating junction temperature for the F280037CSPN?
The F280037CSPN has a specified junction temperature range of –40°C to 150°C. This rating applies to all package variants including the 80-pin PN LQFP used in the F280037CSPN. Thermal design must ensure that under worst-case power dissipation and ambient conditions, the silicon die does not exceed 150°C to maintain reliability and functional safety integrity per ISO 26262 requirements.
Does the F280037CSPN support functional safety certification out of the box?
The F280037CSPN itself is not individually certified, but Texas Instruments provides ISO 26262 ASIL B and IEC 61508 SIL 2 certification documentation for the F280037C-Q1 variant in PZ and Q100 PM packages. While the F280037CSPN (commercial-grade PN package) shares identical hardware architecture and safety mechanisms, system-level certification requires validation within the target application context using TI's safety manual and FMEDA reports.
How many independent ADC modules does the F280037CSPN integrate, and what is their sampling rate?
The F280037CSPN integrates three independent 12-bit Analog-to-Digital Converters (ADCs), each capable of 4 MSPS sampling. The conversion time is 250 ns, and they support up to 25 external single-ended input channels (including two gpdac outputs). All three ADCs can be triggered synchronously, enabling precise phase-aligned current and voltage measurements in multi-phase power converters.
What is the role of the Configurable Logic Block (CLB) in the F280037CSPN?
The Configurable Logic Block (CLB) in the F280037CSPN consists of four independent logic tiles that implement user-defined digital logic functions - such as position manager state machines, custom PWM generators, or hardware-based fault filters - directly on the MCU die. This eliminates need for external CPLDs/FPGAs in motor control and power conversion applications, reducing board area, latency, and component count while maintaining deterministic timing.
Can the F280037CSPN execute control algorithms simultaneously on both the C28x CPU and CLA?
Yes, the F280037CSPN supports true parallel execution: the C28x CPU and CLA operate independently at 120 MHz each, with dedicated memory spaces and direct peripheral access. For example, the CPU can handle communication stack and diagnostics while the CLA runs the inner current control loop at 20 kHz with zero CPU intervention - verified in TI's C2000Ware motor control libraries and documented in SPRSP61C Section 7.7.
