Texas Instruments F280025PMSR

Overview

F280025PMSR 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 resolution) for high-precision power electronics control in solar inverters, EV charging stations, and industrial motor drives.

For engineers reviewing the F280025PMSR datasheet, F280025PMSR pinout, F280025PMSR application, or F280025PMSR equivalent, key selection criteria include dual 3.45MSPS 12-bit ADCs with four post-processing blocks, integrated CLB for custom logic augmentation, and FSI interface supporting up to 200Mbps isolated communication.

Technical Context

The F280025PMSR implements a deterministic real-time control architecture centered on the C28x CPU core augmented by TMU and VCRC instruction sets for accelerated trigonometric and CRC operations. Its analog subsystem tightly couples two 12-bit ADCs with ePWM and CMPSS modules to enable closed-loop control with sub-microsecond latency.

System-level timing is managed via dual zero-pin 10MHz oscillators, PLL-based clock synthesis, and dual-clock comparator (DCC) for voltage monitoring. The device supports functional safety development per ISO 26262 and IEC 61508 with hardware BIST, MPOST, and ERAD diagnostic features.

Key Specifications

Pinout & Package

64-pin Low-profile Quad Flatpack (LQFP) package with 0.5mm pitch, 12mm × 12mm body size, and exposed thermal pad. Pin count and peripheral mapping align with PM-suffix variants across the F28002x family.

Equivalent & Alternatives

The following parts are listed as comparable options for similar real-time control applications.

Compared with F280025PMSR, the F280025C adds CLB-based hardware acceleration for motor-specific functions but shares identical timing performance and analog subsystem specs, while the F280023 reduces flash and removes CLB to lower BOM cost in less complex control systems.

FAQ

What is the maximum operating frequency of the C28x core in F280025PMSR?

The F280025PMSR integrates a C28x 32-bit DSP core operating at 100MHz. This fixed-frequency operation enables deterministic real-time execution of control algorithms, with cycle-accurate timing verified across temperature and voltage ranges per TI's production characterization data.

Does F280025PMSR support functional safety certification out-of-the-box?

F280025PMSR provides hardware features required for functional safety development-including hardware BIST, MPOST, ERAD, and windowed watchdog-but does not ship with pre-certified ASIL or SIL documentation. TI supplies safety manuals and FMEDA reports to aid ISO 26262 and IEC 61508 system-level certification of designs using F280025PMSR.

How many analog input channels does F280025PMSR support in its 64-pin LQFP package?

In the 64-pin LQFP (PM) package, F280025PMSR supports 16 analog input channels-accessible through dedicated AIO pins and multiplexed GPIOs. These feed into two independent 12-bit ADCs capable of simultaneous sampling and hardware post-processing.

What is the role of the Configurable Logic Block (CLB) in F280025PMSR?

F280025PMSR does not include a Configurable Logic Block (CLB). That feature is present only in the 'C' variants (e.g., F280025C). The F280025PMSR retains full C28x CPU, analog, and control peripheral functionality but omits CLB tiles to reduce cost and complexity for non-motor-specific applications.

Can F280025PMSR directly interface with isolated gate drivers?

Yes, F280025PMSR supports direct interface with isolated gate drivers via its 14 ePWM outputs, which include programmable dead-band generation and hardware trip-zone inputs (FLT1/FLT2) for immediate fault shutdown. Its 3.3V logic-level outputs are compatible with standard digital isolators and level-shifted gate driver inputs.
