Product details
Overview
F280034SPT from Texas Instruments is a C28x-based real-time microcontroller with 120 MHz DSP core, IEEE 754 FPU, CLA accelerator, 128KB 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 for FPGA-like logic - deployed in servo drives, solar inverters, and EV charging power modules.
For engineers reviewing the F280034SPT datasheet, F280034SPT pinout, F280034SPT application, or F280034SPT equivalent, key selection criteria include flash size (128KB), CLA availability, CLB absence, 48-pin LQFP package, -40°C to 125°C temperature range, and functional safety qualification status.
Technical Context
The F280034SPT implements a deterministic real-time control architecture centered on a 120 MHz C28x CPU with IEEE 754 single-precision FPU, TMU, and VCRC extensions - enabling fast NLPID, trigonometric, and CRC-intensive control loops. Its CLA runs parallel 120 MHz floating-point code with dedicated memory and direct peripheral access.
Unlike higher-tier F28003x variants, F280034SPT omits the Configurable Logic Block (CLB) but retains full ePWM, SDFM, CMPSS, and HIC support. It uses two internal 10-MHz oscillators, supports crystal/external clock input, and includes BOR, windowed watchdog, and dual-clock comparator for robust system timing integrity.

Equivalent & Alternatives
The following parts are listed as comparable options for similar real-time control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMS320F280034-Q1 | AEC-Q100 qualified (Grade 1), same 48-pin PT package, identical peripherals and memory map | Required for automotive body electronics, EPS, or HVAC compressor modules needing functional safety compliance | Select when ASIL-B readiness and automotive qualification are mandatory - no PCB changes needed |
| TMS320F280037C | 100-pin PZ package, 256KB flash, 4 CLB tiles, enhanced analog channel count (25 ADC inputs) | Suitable for complex multi-axis servo systems requiring FPGA-augmented logic and expanded I/O | Choose for higher integration density and CLB-based position manager implementation - requires PCB redesign |
Compared with F280034SPT, the F280034-Q1 adds automotive qualification without altering functionality, while F280037C expands flash, I/O, and logic capability at the cost of larger footprint and higher BOM cost - making F280034SPT optimal for cost-sensitive, space-constrained industrial power modules.

FAQ
What is the maximum operating frequency of the C28x CPU in F280034SPT?
The F280034SPT features a C28x 32-bit DSP core running at 120 MHz - confirmed in TI's SPRSP61C datasheet Section 1 and Table 4-1. This frequency applies to both fixed- and floating-point instruction execution, supported by on-chip PLL and dual internal oscillators. The CLA also operates at 120 MHz independently. F280034SPT maintains this speed across its full –40°C to 125°C temperature range.
Does F280034SPT include a Configurable Logic Block (CLB)?
No, F280034SPT does not include a Configurable Logic Block. Per TI's Device Comparison Table (SPRSP61C Section 4), CLB is only present on "C" suffix variants (e.g., F280039C, F280037C) and absent on base variants like F280034 and F280034SPT. This omission reduces logic flexibility but maintains full ePWM, ADC, and communications peripheral functionality.
What is the flash memory configuration of F280034SPT?
F280034SPT contains 128KB (64KW) of ECC-protected flash memory organized into two independent 64KB banks. This structure enables simultaneous code execution from one bank while programming the other - essential for Live Firmware Update (LFU) operation. The flash supports 100K write/erase cycles and retains data for 20 years at 85°C, per TI's specification in Section 6.6.
Which CAN protocols does F280034SPT support?
F280034SPT supports two physically separate CAN interfaces: one legacy DCAN port compliant with ISO 11898-1 (Classical CAN), and one MCAN port supporting CAN FD (Flexible Data-Rate) per ISO 11898-1:2015. Both interfaces operate concurrently, with independent message RAM and filtering - enabling hybrid networks where legacy ECUs communicate alongside high-bandwidth CAN FD nodes.
Is F280034SPT qualified for automotive applications?
F280034SPT is not AEC-Q100 qualified. Only the F280034-Q1 variant carries AEC-Q100 Grade 1 qualification (–40°C to 125°C) and functional safety documentation for ASIL-B systems. F280034SPT is rated for industrial temperature range (–40°C to 125°C) and lacks the automotive-specific test reports, failure-in-time (FIT) data, and safety manual required for automotive deployment.
