Product details
Overview
F280025PTSR 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 capability), designed for digital power control in solar inverters, EV charging stations, and industrial motor drives.
For engineers reviewing the F280025PTSR datasheet, F280025PTSR pinout, F280025PTSR application, or F280025PTSR equivalent, key selection criteria include its 48-pin LQFP package, dual 3.45MSPS 12-bit ADCs with four integrated PPBs, CLB support for custom logic augmentation, and functional safety documentation for ISO 26262 system design.
Technical Context
The F280025PTSR integrates a deterministic C28x DSP core with TMU and VCRC accelerators to accelerate trigonometric and CRC-intensive real-time control loops. Its analog subsystem tightly couples two 12-bit ADCs (3.45MSPS) and four windowed comparators (CMPSS) with 12-bit internal DACs for fast overcurrent protection and closed-loop feedback.
Control peripherals include 14 ePWM channels supporting frequency-independent resolution modes, three eCAP modules (one with HRCAP), two eQEP interfaces for position sensing, and a Configurable Logic Block (CLB) enabling FPGA-like logic insertion without external components - all synchronized via shared XBAR routing and ERAD for runtime diagnostics.

How many ADC channels are accessible on the F280025PTSR in its 48-pin PT package?
The F280025PTSR supports up to 14 single-ended ADC input channels in the 48-pin LQFP (PT) package, derived from its dual 12-bit ADC subsystem. This count is confirmed in TI's Device Comparison table and aligns with pin availability and analog multiplexer routing for the PT variant.
Can the F280025PTSR's CLB be used to replace external logic components in power stage control?
Yes, the Configurable Logic Block (CLB) in the F280025PTSR enables implementation of custom combinational or sequential logic - such as encoder index pulse conditioning, fault signal arbitration, or dead-time extension - directly on-chip, eliminating the need for external CPLDs or discrete glue logic in compact power module designs.
Is the F280025PTSR pin-compatible with other members of the F28002x family in the same PT package?
Yes, all F28002x devices in the 48-pin PT package - including F280025PTSR, F280023PTSR, and F280021PTSR - share identical pinouts, electrical characteristics, and mechanical dimensions, enabling hardware reuse across performance tiers while maintaining software compatibility through TI's C2000Ware SDK.
