Product details
Overview
F280037CSPZ 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 200 Mbps, and CLB with 4 tiles-targeting high-efficiency motor control in AC inverters, servo drives, and GaN/SiC power stages.
For engineers reviewing the F280037CSPZ datasheet, F280037CSPZ pinout, F280037CSPZ application, or F280037CSPZ equivalent, key selection criteria include CLA-enabled deterministic control loop offload, functional safety support (ASIL B/SIL 2) in PZ package, 100-pin LQFP thermal performance, and live firmware update capability for zero-downtime field updates.
Technical Context
The F280037CSPZ implements a dual-core real-time architecture: the C28x CPU executes main control code at 120 MHz with FPU, TMU, and VCRC extensions, while the independent CLA runs parallel floating-point tasks at 120 MHz using dedicated message RAM and direct peripheral access. Its analog subsystem tightly couples three 12-bit ADCs with ePWM triggers and post-processing blocks for closed-loop current/voltage sensing.
Control peripherals include 16 ePWM channels with integrated dead-band and hardware trip zones, three eCAP modules (one with HRCAP), two eQEP interfaces, and eight SDFM input channels for isolated current sensing. The device supports secure boot, JTAGLOCK, dual-zone security, and AES acceleration for firmware integrity and IP protection.

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 100-pin PZ package | Supports larger control algorithms and dual-bank firmware storage for complex energy management systems | Select when >256KB flash required for multi-axis motion profiles or encrypted firmware partitioning |
| TMS320F280037C-Q1 | Automotive AEC-Q100 Grade 1 qualification (–40°C to 125°C TA), identical electrical specs and pinout | Required for automotive traction inverters, EPS, or ADAS power modules subject to automotive qualification | Select for automotive production programs requiring documented functional safety evidence and PPAP support |
Compared with TMS320F280039C, F280037CSPZ trades 128KB flash for cost-sensitive industrial applications while retaining full CLA, CLB, and analog performance; versus F280037C-Q1, it omits automotive qualification but offers identical real-time control capability for non-automotive use cases.

FAQ
What is the maximum operating junction temperature for F280037CSPZ?
The F280037CSPZ has a specified junction temperature range of –40°C to 150°C per TI's SPRSP61C datasheet. This rating applies to the 100-pin PZ package and enables operation in high-power-density motor control environments where thermal management is critical. The device includes built-in thermal monitoring circuitry and supports software-configurable thermal shutdown thresholds. F280037CSPZ maintains full specification compliance across this entire range when used with appropriate PCB copper pour and airflow.
Does F280037CSPZ support functional safety certification out of the box?
F280037CSPZ itself is not certified; however, the PZ package variant (which matches F280037CSPZ's 100-pin LQFP form factor) is explicitly qualified to ISO 26262 ASIL B and IEC 61508 SIL 2 by TÜV SÜD. Documentation including FMEDA reports, safety manuals, and diagnostic coverage analysis is provided by Texas Instruments for system-level integration. F280037CSPZ must be used with certified hardware design practices and safety firmware to achieve end-system compliance.
How many independent ADC modules does F280037CSPZ integrate, and what is their sampling rate?
F280037CSPZ integrates three independent 12-bit Analog-to-Digital Converters (ADCs), each capable of 4 MSPS sampling. Each ADC supports up to 25 external channels in the 100-pin PZ package, with hardware synchronization to ePWM timers for precise current/voltage sampling in motor control loops. Conversion time is 250 ns, and each ADC includes four post-processing blocks (PPBs) for real-time filtering and offset correction without CPU overhead.
Can F280037CSPZ execute code from RAM while programming flash?
Yes, F280037CSPZ supports concurrent execution and programming due to its three independent flash banks. While Bank 0 is being erased or programmed, the C28x CPU and CLA can execute code from Bank 1 or Bank 2. This capability is essential for Live Firmware Update (LFU) operations and enables zero-downtime field upgrades. The device's memory map reserves dedicated RAM regions (LS, GS, message RAM) for real-time task execution during flash maintenance cycles.
What communication interfaces with isolation capability does F280037CSPZ provide?
F280037CSPZ provides Fast Serial Interface (FSI) with dedicated TX and RX lanes supporting up to 200 Mbps across galvanic isolation boundaries. Unlike optocoupler-based solutions, FSI uses differential signaling and embedded clock recovery for robust noise immunity. It is commonly paired with TI's ISO7842 or ISO7742 digital isolators. No other interface (CAN, SPI, I²C) on F280037CSPZ includes native isolation-external isolators are required for those buses.
