Texas Instruments F2800132RGZR

Overview

F2800132RGZR from Texas Instruments is a 100-MHz C28x real-time microcontroller optimized for power electronics control, featuring 64KB flash, 36KB ECC/parity-protected RAM, dual 12-bit 3.45-MSPS ADCs, and 14 ePWM channels (2 with 150-ps resolution) - deployed in motor drives, UPS, and solar charge controllers.

For engineers reviewing the F2800132RGZR datasheet, F2800132RGZR pinout, F2800132RGZR application, or F2800132RGZR equivalent, key selection criteria include its 100-MHz C28x DSP core with TMU/FPU acceleration, VQFN-48 package with 38 GPIO (11 shared analog), integrated CMPSS/CMPSS_LITE comparators, CAN/SCI/I2C/SPI interfaces, and –40°C to 125°C operating range.

Technical Context

The F2800132RGZR implements TI's C28x 32-bit DSP CPU at 100 MHz with Trigonometric Math Unit (TMU) and Floating Point Unit (FPU32) for deterministic real-time signal processing in closed-loop power conversion. Its analog subsystem tightly couples two 12-bit ADCs (3.45 MSPS, 290 ns conversion time) with four post-processing blocks per ADC and three windowed comparators (CMPSS_LITE) with 9.5-bit effective DACs.

Control peripherals include 14 ePWM channels (2 high-resolution), two eCAP modules, one eQEP module supporting CW/CCW operation, and embedded pattern generator (EPG). System-level features comprise dual internal 10-MHz oscillators, crystal/external clock input, windowed watchdog timer, missing clock detection, and dual-clock comparator (DCC).

FAQ

What is the maximum operating frequency of the C28x CPU in the F2800132RGZR?

The F2800132RGZR features a C28x 32-bit DSP CPU operating at 100 MHz. This frequency is fixed and guaranteed across the full –40°C to 125°C ambient temperature range and 3.3-V ±5% supply, enabling deterministic real-time execution for time-critical control loops in power electronics applications.

Does the F2800132RGZR include hardware floating-point and trigonometric math acceleration?

Yes, the F2800132RGZR integrates both a Floating Point Unit (FPU32) and Trigonometric Math Unit (TMU). These accelerators enable efficient execution of floating-point arithmetic and common trigonometric functions - critical for field-oriented control (FOC) and sensorless motor algorithms - without software emulation overhead.

How many ADC channels does the F2800132RGZR support, and what is their sampling rate?

The F2800132RGZR integrates two independent 12-bit Analog-to-Digital Converters (ADCs), each capable of up to 3.45 million samples per second (MSPS) with 290 ns conversion time. Up to 21 external channels are supported (11 shared with GPIO), and each ADC includes four post-processing blocks for real-time result filtering and offset correction.

What communication interfaces are available on the F2800132RGZR?

The F2800132RGZR provides one Controller Area Network (CAN) port, three UART-compatible Serial Communication Interfaces (SCI), one Serial Peripheral Interface (SPI), and two Inter-Integrated Circuit (I2C) interfaces. All are accessible on the 48-pin VQFN package via multiplexed GPIO pins, supporting host communication, sensor interfacing, and system-level bus connectivity.

Is the F2800132RGZR pin-compatible with other members of the TMS320F280013x family in the same package option?

Yes, the F2800132RGZR is pin-compatible with F2800133RGZR, F2800135RGZR, and F2800137RGZR in the 48-pin VQFN (RGZ) package. Signal mapping, power/ground pin locations, and peripheral pin assignments are identical - allowing drop-in replacement where functional requirements align.
