Texas Instruments F280025CPTSRG4

Overview

F280025CPTSRG4 from Texas Instruments is a C28x-based real-time microcontroller designed for high-efficiency power electronics control, featuring a 100MHz DSP core with IEEE 754 FPU, 128KB ECC-protected flash, 24KB RAM (ECC/parity), and dual-zone security. It integrates 14 ePWM channels (8 with 150ps high-resolution), two 3.45MSPS 12-bit ADCs, four CMPSS modules with 12-bit DACs, and CLB logic tiles - deployed in solar inverters, EV charging power modules, and industrial motor drives.

For engineers reviewing the F280025CPTSRG4 datasheet, F280025CPTSRG4 pinout, F280025CPTSRG4 application, or F280025CPTSRG4 equivalent, key selection criteria include high-resolution PWM timing accuracy, on-chip analog signal chain latency, CLB configurability for custom protection logic, and functional safety documentation support for ISO 26262 system integration.

Technical Context

The F280025CPTSRG4 implements a deterministic real-time control architecture centered on the C28x CPU with TMU and VCRC acceleration units, enabling fast trigonometric and CRC operations critical for NLPID control loops and firmware integrity checks. Its dual ADC subsystem feeds directly into ePWM trip zones and CLB logic, supporting sub-microsecond closed-loop response.

System-level timing is governed by dual zero-pin oscillators (10MHz), PLL-based clock synthesis, and DCC circuitry for clock fault detection. The HIC interface provides external host access to internal memory without CPU intervention, while ERAD and BGCRC enable runtime diagnostics and background data integrity verification.

FAQ

What is the operating temperature range for F280025CPTSRG4?

F280025CPTSRG4 is rated for junction temperatures from –40°C to 125°C, meeting industrial and extended-temperature requirements. This rating applies to the PT-package variant and is validated per TI's thermal characterization data for the 48-pin LQFP configuration. The 'S' temperature grade ensures reliability in high-ambient environments such as enclosed power converters and outdoor EV charging stations. F280025CPTSRG4 does not carry AEC-Q100 qualification - that designation applies only to Q1 variants like F280025CPTSQ4.

Does F280025CPTSRG4 include hardware cryptographic acceleration?

F280025CPTSRG4 does not integrate dedicated cryptographic accelerators (e.g., AES, SHA, RSA engines). Security relies on dual-zone code/data protection, secure boot ROM, and DCSM-based flash locking. For applications requiring certified encryption, external secure elements or software-based libraries running on the C28x FPU are recommended. F280025CPTSRG4 supports memory integrity checks via BGCRC and hardware self-tests (HWBIST), but no on-die crypto IP is present per the device's functional block diagram and peripheral list.

How many analog input channels does F280025CPTSRG4 support in the PT package?

In the 48-pin PT package, F280025CPTSRG4 supports 14 analog input channels - accessible via A0–A15 and C0–C15 pins with appropriate multiplexing. These channels feed into two independent 12-bit ADCs, each capable of 3.45MSPS sampling. The PT variant maps 14 of the 16 total possible A/C inputs; the remaining two (e.g., A14, C4) are not bonded out in this package. All 14 channels support simultaneous sampling when configured in interleaved mode.

Is F280025CPTSRG4 pin-compatible with other F28002x devices in the PT package?

Yes - F280025CPTSRG4 shares identical pinout, electrical characteristics, and mechanical footprint with all other PT-package F28002x variants including F280025PTSR, F280023CPTSR, and F280021PTSR. Pin functions (e.g., GPIO, ADC, ePWM) are consistent across these parts; differences lie solely in internal configuration (e.g., CLB presence, flash size, RAM allocation). This allows direct PCB reuse when migrating between F28002x-PT devices during design optimization or cost scaling.

What development tools are officially supported for F280025CPTSRG4?

F280025CPTSRG4 is fully supported by TI's C2000Ware software suite, Code Generation Tools v22.x+, and CCS v12.x IDE. Hardware evaluation is enabled via the TMDSCNCD280025C controlCARD, which provides JTAG debugging, ePWM signal probing, and ADC stimulus injection. TI also provides motor control SDKs, solar inverter reference designs (e.g., TIDM-02007), and functional safety libraries aligned with ISO 26262 ASIL-B requirements for F280025CPTSRG4.
