Product details
Overview
TMS320F2800137RGZR from Texas Instruments is a 120-MHz C28x real-time microcontroller with FPU and TMU acceleration, 256KB ECC-protected flash, 36KB ECC/parity-protected RAM, dual 4-MSPS 12-bit ADCs, 14 ePWM channels (2 with 150-ps resolution), and integrated CAN, SPI, I²C, and SCI interfaces - deployed in motor control for AC drive power stages and solar charge controllers.
For engineers reviewing the TMS320F2800137RGZR datasheet, TMS320F2800137RGZR pinout, TMS320F2800137RGZR application, or TMS320F2800137RGZR equivalent, key selection criteria include real-time signal chain latency, high-resolution PWM timing precision, on-chip analog subsystem integration, and industrial temperature operation (–40°C to 125°C).
Technical Context
The TMS320F2800137RGZR implements TI's C28x DSP core with hardware-accelerated trigonometric math (TMU) and floating-point unit (FPU32), enabling deterministic execution of field-oriented control (FOC) and sensorless algorithms at 120 MHz. Its dual-clock comparator (DCC) and windowed watchdog provide robust system monitoring.
Analog-peripheral coupling includes two 12-bit ADCs with 250-ns conversion time and four post-processing blocks per ADC, synchronized directly to ePWM triggers. The 14-channel ePWM subsystem integrates dead-band generation, hardware trip zones (TZ), and high-resolution capability on two channels for precise gate-drive timing in SiC/GaN-based power stages.
