Product details
Overview
F2800133PMR from Texas Instruments is a 120-MHz C28x 32-bit real-time microcontroller optimized for power electronics control, featuring 64KB flash, 36KB ECC/parity-protected RAM, two 4-MSPS 12-bit ADCs, and 14 ePWM channels (2 with 150-ps high-resolution capability), deployed in motor drives and AC-DC converters.
For engineers reviewing the F2800133PMR datasheet, F2800133PMR pinout, F2800133PMR application, or F2800133PMR equivalent, this page delivers verified specifications, package mapping to 64-pin LQFP (PM), confirmed analog/peripheral integration, and validated alternative options for industrial motor control and power supply designs.
Technical Context
The F2800133PMR implements TI's C28x DSP core with integrated Trigonometric Math Unit (TMU) and Floating Point Unit (FPU32), enabling deterministic execution of complex control loops at 120 MHz. Its signal chain architecture tightly couples dual 12-bit ADCs, four post-processing blocks per ADC, and windowed comparators with 12-bit DAC references to minimize latency in closed-loop systems.
System-level timing is managed via dual internal 10-MHz oscillators, crystal/external clock support, windowed watchdog timer, and Dual-Clock Comparator (DCC). The device supports zero-pin boot and dual-zone security with JTAGLOCK, targeting safety-aware industrial applications operating from –40°C to 125°C ambient temperature.
Key Specifications

| GPIO0–GPIO39 | Configurable I/O | 38 individually programmable GPIOs (11 shared with analog functions) - supports status LEDs, fault signaling, encoder inputs, and digital communication interfaces like SPI slave select. |
Key Features
| Feature | Design Value |
|---|---|
| Trigonometric Math Unit (TMU) | Accelerates sin/cos/tan/arctan calculations in <100 cycles - reduces CPU load for FOC angle computation and improves loop update rate by up to 3×. |
| Embedded Pattern Generator (EPG) | Hardware waveform generator synchronized to ePWM timers - eliminates software overhead for generating complex gate drive sequences in resonant LLC or multi-phase inverters. |
| Windowed Watchdog Timer | Configurable timeout window with early-warning interrupt - detects both stuck and runaway code while allowing safe shutdown in motor control fault conditions. |
| Dual-Clock Comparator (DCC) | Monitors system clock integrity using independent reference oscillator - triggers reset if main PLL fails, preventing erratic PWM output during clock instability. |
| Zero-pin Boot Mode | Automatic boot from flash without external configuration pins - simplifies PCB layout and eliminates boot-strapping resistors for cost-sensitive industrial modules. |
