Product details
Overview
F280025PNSR from Texas Instruments is a 100MHz C28x real-time microcontroller with IEEE 754 FPU, 128KB ECC-protected flash, 24KB RAM (ECC/parity), and 14 ePWM channels (8 with 150ps high-resolution). It integrates dual 3.45MSPS 12-bit ADCs, four CMPSS modules with 12-bit DACs, and FSI up to 200Mbps - designed for digital power control in solar inverters, EV charging stations, and motor drives.
For engineers reviewing the F280025PNSR datasheet, F280025PNSR pinout, F280025PNSR application, or F280025PNSR equivalent, key selection criteria include high-resolution PWM timing accuracy, on-chip analog signal chain integration, functional safety documentation support (ISO 26262/IEC 61508), and CLB-augmented peripheral flexibility for GaN/SiC gate drive control.
Technical Context
The F280025PNSR implements a deterministic real-time control subsystem centered on the C28x 32-bit DSP core, accelerated by TMU for trigonometric functions and VCRC for CRC-32 computation. Its dual-clock comparator (DCC) enables precise timing fault detection, while ERAD provides hardware-assisted runtime diagnostics.
Analog-to-control loop latency is minimized via tightly coupled ADCs with four post-processing blocks per converter and ePWM modules featuring integrated dead-band generation and hardware trip zones. The HIC interface allows external host access to internal memory without CPU intervention.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMS320F280025C | Includes 2 CLB tiles and motor control libraries in ROM; identical core/peripheral specs otherwise | Better suited for position manager solutions requiring FPGA-like logic augmentation | Select F280025C when CLB-based encoder interpolation or custom gate drive logic is required |
| TMS320F280023 | 64KB flash, no CLB, same 100MHz C28x core and peripheral set except reduced GPIO count (30 vs 43) | Targeted at cost-sensitive industrial drives with simpler control requirements | Choose F280023 for compact designs where full 128KB flash and CLB are unnecessary |

FAQ
What is the maximum operating junction temperature for the F280025PNSR?
The F280025PNSR is rated for –40°C to 125°C junction temperature (S-grade). This specification is validated per TI's thermal characterization and supports continuous operation in high-power-density applications such as 3-phase inverters and onboard chargers where ambient temperatures exceed 85°C.
Does the F280025PNSR support AEC-Q100 qualification?
No, the F280025PNSR is the commercial S-grade variant. For automotive applications, TI offers the pin-compatible F280025-Q1, which is AEC-Q100 qualified for Grade 1 (–40°C to 125°C free-air) and includes additional automotive-specific test coverage and documentation.
How many hardware breakpoints does the F280025PNSR support during debug?
The F280025PNSR supports ten hardware breakpoints using the Embedded Real-time Analysis and Diagnostic (ERAD) module. These breakpoints operate independently of code execution flow and remain active during real-time control loops without performance penalty.
Can the F280025PNSR's Fast Serial Interface (FSI) be used across an isolation barrier?
Yes, the F280025PNSR's FSI supports robust 200Mbps communication across galvanic isolation boundaries using standard digital isolators. Its differential signaling and built-in error detection make it ideal for interfacing with isolated gate drivers or auxiliary safety monitors in high-voltage systems.
Is the F280025PNSR pin-compatible with other devices in the F28002x family?
Yes, the F280025PNSR in the 80-pin PN package shares identical pinout with F280025C, F280023, and F280023C in the same package option - enabling hardware reuse across variants with different flash sizes or CLB configurations.
