Overview
TMS320F2800133PTR from Texas Instruments is a 120-MHz C28x real-time microcontroller with FPU and TMU acceleration, 64KB flash, 36KB ECC/parity-protected RAM, dual 4-MSPS 12-bit ADCs, 14 ePWM channels (2 with 150-ps resolution), and integrated CMPSS/CMPSS_LITE comparators - designed for closed-loop motor control in cordless power tools and AC-input BLDC drives.
For engineers reviewing the TMS320F2800133PTR datasheet, TMS320F2800133PTR pinout, TMS320F2800133PTR application, or TMS320F2800133PTR equivalent, key selection criteria include its 120-MHz deterministic C28x DSP core, on-chip analog signal chain integration (ADC + CMPSS + ePWM), 48-pin LQFP package with 38 GPIO (11 shared analog), and support for CAN, SPI, I²C, and three SCI interfaces.
Technical Context
The TMS320F2800133PTR implements TI's C28x 32-bit DSP CPU at 120 MHz with hardware-accelerated floating-point (FPU32) and trigonometric math (TMU), enabling sub-microsecond loop closure in digital power and motor control. Its dual 12-bit ADCs operate at 4 MSPS with four post-processing blocks per converter and support up to 21 external channels.
Control peripherals include 14 ePWM channels (2 with high-resolution 150-ps timing), two eCAP modules, one eQEP module with CW/CCW support, and four comparator subsystems (1× CMPSS with dynamic 12-bit DACs, 3× CMPSS_LITE with 9.5-bit static DACs). System-level features include dual internal 10-MHz oscillators, windowed watchdog, missing-clock detection, and DCC.

Equivalent & Alternatives
The following parts are listed as comparable options for similar real-time control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMS320F2800135PTR | 128KB flash, same 120-MHz C28x core, identical peripheral set and pinout - differs only in flash capacity and security ROM footprint. | Supports larger control algorithms (e.g., dual-motor FOC + communication stack) without external memory expansion. | Select when firmware complexity exceeds 64KB or when future-proofing for feature upgrades is required. |
| TMS320F2800132PTR | 100-MHz C28x core, same 64KB flash and peripheral complement - lacks HRPWM capability and has reduced ADC performance (3.45 MSPS). | Suitable for cost-sensitive, lower-bandwidth applications like basic fan control or simple pump drives where sub-µs loop timing is not critical. | Select for entry-level designs where 120-MHz performance and 150-ps PWM resolution are unnecessary. |
Compared with TMS320F2800135PTR, the TMS320F2800133PTR trades flash capacity for lower cost and smaller code footprint; compared with TMS320F2800132PTR, it delivers higher deterministic throughput and hardware-enhanced timing precision essential for advanced motor control.

Yes, the TMS320F2800133PTR integrates a Trigonometric Math Unit (TMU) that accelerates sin, cos, arctan, and sqrt operations in hardware. This unit reduces execution time for Park/Clarke transforms and other control-law computations by more than 80% compared to software-only C28x instruction execution - a critical advantage for high-bandwidth field-oriented control (FOC) loops.
How many analog input channels does the TMS320F2800133PTR support, and what is their resolution and speed?
The TMS320F2800133PTR integrates two independent 12-bit analog-to-digital converters (ADCs), each capable of 4 MSPS sampling. It supports up to 21 external analog input channels (11 shared with GPIO), with dedicated pins mapped to ADC-A and ADC-C modules. Conversion time is 250 ns, and each ADC includes four post-processing blocks (PPB) for hardware-based calibration and filtering.
What package type and pin count does the TMS320F2800133PTR use?
The TMS320F2800133PTR uses a 48-pin Low-profile Quad Flatpack (LQFP) package, designated by the "PT" suffix. The package measures 9 mm × 9 mm with 0.5-mm pitch, includes an exposed thermal pad, and is RoHS-compliant. It provides 38 general-purpose I/O pins (11 of which are analog-capable), along with dedicated power, ground, clock, and communication interface pins.
Does the TMS320F2800133PTR include built-in comparator subsystems, and if so, what types?
Yes, the TMS320F2800133PTR integrates four comparator subsystems: one full CMPSS (with two comparators and two dynamic 12-bit DACs) and three CMPSS_LITE modules (each with two comparators and two static 9.5-bit effective DACs).
