Product details
Overview
F2800135RGZR from Texas Instruments is a 120-MHz C28x real-time microcontroller optimized for power electronics control, featuring 128KB flash, 36KB ECC/parity-protected RAM, dual 4-MSPS 12-bit ADCs, 14 ePWM channels (2 with 150-ps resolution), and integrated CMPSS comparators - deployed in AC drive control modules, BLDC motor drives, and solar charge controllers.
For engineers reviewing the F2800135RGZR datasheet, F2800135RGZR pinout, F2800135RGZR application, or F2800135RGZR equivalent, key selection criteria include real-time signal chain latency, on-chip analog integration for closed-loop control, high-resolution PWM timing accuracy, and industrial temperature operation (–40°C to 125°C).
Technical Context
The F2800135RGZR implements TI's C28x 32-bit DSP core with Floating Point Unit (FPU32) and Trigonometric Math Unit (TMU), enabling deterministic execution of complex control algorithms such as field-oriented control (FOC) and sensorless commutation. Its dual 12-bit ADCs support up to 21 external channels with four post-processing blocks (PPB) per ADC for real-time digital filtering and thresholding.
Control peripherals include two eCAP modules, one eQEP module (CW/CCW support), embedded pattern generator (EPG), and hardware trip zones (TZs) for fast fault response. Communication is supported via one CAN port, three UART-compatible SCI interfaces, two I²C ports, and one SPI port - all accessible on the 48-pin VQFN (RGZ) package with full pin multiplexing.

Equivalent & Alternatives
The following parts are listed as comparable options for similar real-time control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMS320F2800137RGZR | 256KB flash, same 120-MHz C28x core, identical peripherals and pinout - differs only in flash capacity and security features. | Required where firmware complexity exceeds 128KB or dual-zone security is mandated for firmware updates. | Select F2800137RGZR when future firmware expansion or secure OTA updates are needed; otherwise F2800135RGZR offers optimal cost/performance balance. |
| TMS320F280025CRGZR | 100-MHz C28x core, 128KB flash, adds CLA accelerator and CAN-FD - lacks CMPSS_LITE and has reduced ADC channel count (16 vs 21). | Better suited for applications needing parallel processing (CLA) or automotive-grade CAN-FD, but less optimal for high-channel-count analog sensing. | Choose F280025CRGZR for CAN-FD networking or CLA-assisted control; retain F2800135RGZR for pure analog-rich, high-speed PWM applications. |
Compared with F2800137RGZR, F2800135RGZR trades flash capacity for lower unit cost while retaining identical real-time performance and analog integration; versus F280025CRGZR, it prioritizes ADC channel density and comparator subsystem depth over CLA acceleration and CAN-FD.

FAQ
What is the maximum operating frequency of the F2800135RGZR CPU core?
The F2800135RGZR features a C28x 32-bit DSP core running at 120 MHz - delivering deterministic real-time performance for control loops with sub-microsecond timing requirements. This frequency is fixed and not user-configurable; it is sustained across the full –40°C to 125°C ambient temperature range specified for the F2800135RGZR device.
Does the F2800135RGZR support hardware-based overcurrent protection?
Yes, the F2800135RGZR integrates one full CMPSS (with dynamic 12-bit DAC) and three CMPSS_LITE modules (each with 9.5-bit effective DAC). These comparators generate immediate hardware trip signals that feed directly into ePWM trip zones, enabling <100 ns response to overcurrent events - a critical feature for protecting IGBTs and SiC MOSFETs in the F2800135RGZR-based power stages.
How many analog input channels does the F2800135RGZR support?
The F2800135RGZR supports up to 21 external analog input channels across its two 12-bit ADCs, with 11 channels shared between analog and GPIO functions. Channel allocation is configurable via the analog input multiplexer (XBAR), and all channels are accessible in the 48-pin RGZ package - confirmed in the device-specific pin multiplexing table for F2800135RGZR.
Is the F2800135RGZR pin-compatible with other devices in the F280013x family?
Yes, the F2800135RGZR shares identical pinout and package dimensions with F2800137RGZR, F2800133RGZR, and F2800132RGZR in the 48-pin VQFN (RGZ) variant. All RGZ-packaged F280013x devices use the same mechanical footprint and signal mapping - allowing direct substitution in PCB layouts where flash size, ADC speed, or peripheral count differences are acceptable.
What development tools are recommended for the F2800135RGZR?
Texas Instruments recommends the TMDSCNCD2800137 controlCARD as the primary evaluation platform for the F2800135RGZR, paired with C2000Ware software suite and Code Generation Tools. The F2800135RGZR is fully supported in CCS v12+ and includes device-specific examples for ePWM, ADC, CAN, and CMPSS - all validated for the exact F2800135RGZR silicon revision.
