Product details
Overview
TMS320F280025PTS 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 14 ePWM channels with 8 supporting 150ps resolution - deployed in solar inverters, EV charging power modules, and industrial motor drives.
For engineers reviewing the TMS320F280025PTS datasheet, TMS320F280025PTS pinout, TMS320F280025PTS application, or TMS320F280025PTS equivalent, key selection criteria include its 48-pin LQFP package, dual 3.45MSPS 12-bit ADCs with four post-processing blocks, integrated CLB for custom logic augmentation, and functional safety documentation support for ISO 26262 system design.
Technical Context
The TMS320F280025PTS implements TI's C28x 32-bit CPU with hardware-accelerated TMU and VCRC instructions for real-time control math, paired with two independent 12-bit ADCs tightly coupled to ePWM and CMPSS peripherals for closed-loop timing-critical sampling. Its 48-pin LQFP (PT suffix) supports 20 GPIOs, 14 analog inputs, and dedicated HIC interface for external host memory access.
System-level timing is managed via dual internal 10MHz oscillators, PLL, windowed watchdog, and DCC; power integrity includes single 3.3V supply with internal VREG, BOR, and brownout reset - all qualified for –40°C to 125°C junction operation per S-grade specification.

FAQ
What is the operating temperature range for the TMS320F280025PTS?
The TMS320F280025PTS is rated for –40°C to 125°C junction temperature (S-grade), validated for continuous operation in industrial and automotive under-hood environments. This rating is confirmed in TI's SPRSP45C datasheet Section 6.4 and applies specifically to the PT-package variant with S-temperature marking.
Does the TMS320F280025PTS include hardware cryptographic acceleration?
No, the TMS320F280025PTS does not integrate dedicated cryptographic accelerators such as AES or SHA engines. It supports secure boot and code protection via DCSM dual-zone security and BGCRC for firmware integrity, but encryption/decryption operations must be implemented in software using the C28x CPU and FPU.
How many analog input channels are supported on the TMS320F280025PTS package?
The TMS320F280025PTS in the 48-pin LQFP (PT) package supports 14 external analog input channels, as specified in Table 4-1 of the SPRSP45C datasheet. These are distributed across A0–A15 and C0–C15 pins with multiplexing, and include dedicated VREFHI/VREFLO references for ADC calibration.
Is the TMS320F280025PTS pin-compatible with other F28002x family members in the same package?
Yes, the TMS320F280025PTS shares identical pinout and electrical characteristics with TMS320F280023PTS and TMS320F280021PTS in the 48-pin PT package, as confirmed by TI's Package Information table and Pin Diagram Figure 5-3. All three variants maintain full hardware compatibility at the board level.
What development tools are officially supported for the TMS320F280025PTS?
Texas Instruments officially supports the TMS320F280025PTS with C2000Ware software suite, Code Generation Tools v22.x+, and the TMDSCNCD280025C evaluation board. Debugging is enabled via JTAG/cJTAG using XDS110 or XDS200 emulators, and real-time analysis uses ERAD and CCS EnergyTrace+.
