Product details
Overview
TMS320F280025PTQR from Texas Instruments is a C2000™ real-time microcontroller featuring a 100MHz C28x DSP core with IEEE 754 FPU, 128KB ECC-protected flash, 24KB RAM (ECC/parity), 14 ePWM channels (8 with 150ps resolution), and dual 3.45MSPS 12-bit ADCs - designed for high-efficiency power electronics control in solar inverters, EV charging, and motor drives.
For engineers reviewing the TMS320F280025PTQR datasheet, TMS320F280025PTQR pinout, TMS320F280025PTQR application, or TMS320F280025PTQR equivalent, key selection criteria include AEC-Q100 qualification (Q-grade), 48-pin LQFP package, CLB absence (vs. -C variants), integrated CMPSS with 12-bit DACs, and FSI support up to 200Mbps for isolated communication.
Technical Context
The TMS320F280025PTQR implements a deterministic real-time control architecture centered on the C28x CPU augmented by TMU and VCRC instructions for fast trigonometric and CRC operations. Its analog subsystem tightly couples dual 12-bit ADCs with four windowed comparators (CMPSS) and post-processing blocks for closed-loop timing-critical feedback.
Control peripherals include 14 ePWM channels with independent dead-band and trip-zone logic, three eCAP modules (one with HRCAP), two eQEP interfaces, and a Host Interface Controller (HIC) enabling external host access to internal memory - all synchronized via a shared crossbar and clock domain management including dual zero-pin oscillators and PLL.

Equivalent & Alternatives
The following parts are listed as comparable options for similar real-time control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMS320F280025CPTQR | Includes 2 CLB tiles and motor control libraries in ROM; identical pinout and peripherals otherwise | Required when custom logic (e.g., position manager, encoder interpolation) must run in hardware alongside CPU | Select -C variant only if CLB functionality is needed; adds no cost or footprint penalty |
| TMS320F280023PTQR | 64KB flash, no CLB, same package/peripherals; lower memory capacity and no F280025-specific ROM features | Suitable for cost-sensitive, lower-complexity inverters or motor drives with <100k lines of control code | Choose for reduced BOM cost where flash headroom and advanced ROM libraries are non-critical |
Compared with TMS320F280025CPTQR, the TMS320F280025PTQR omits CLB logic but retains full 128KB flash and identical real-time peripherals - making it optimal for pure software-defined control.

FAQ
What is the maximum operating temperature specification for the TMS320F280025PTQR?
The TMS320F280025PTQR is qualified for –40°C to 125°C free-air temperature (Q-grade), meeting AEC-Q100 Grade 1 requirements. This rating applies to the full 48-pin LQFP package and is validated per TI's automotive qualification test plan, including thermal cycling, HTOL, and ESD testing.
Does the TMS320F280025PTQR include a Configurable Logic Block (CLB)?
No, the TMS320F280025PTQR does not include a Configurable Logic Block. CLB functionality is exclusive to the "C" suffix variants (e.g., TMS320F280025CPTQR). The TMS320F280025PTQR retains all other peripherals - including 14 ePWM channels, dual ADCs, and FSI - but relies solely on C28x CPU execution for logic implementation.

The TMS320F280025PTQR provides 14 single-ended analog input channels in the 48-pin LQFP package, mapped to pins A0–A5, A10–A12, A14–A15, and C0–C2, C4–C5, C7, C9–C10, C14. These connect directly to the two integrated 12-bit ADCs with 3.45MSPS aggregate sampling capability.
What communication interfaces does the TMS320F280025PTQR support for isolated system design?
The TMS320F280025PTQR supports isolated communication via its Fast Serial Interface (FSI), which delivers up to 200Mbps bidirectional data transfer across reinforced insulation barriers. It also supports standard isolated protocols through external transceivers on its CAN, SPI, and UART-compatible SCI/LIN interfaces - all accessible on the 48-pin LQFP package.
Is the TMS320F280025PTQR pin-compatible with other members of the F28002x family in the same package option?
Yes, the TMS320F280025PTQR is pin-compatible with TMS320F280023PTQR and TMS320F280021PTQR in the 48-pin LQFP (PT) package.
