Product details
Overview
TMS320F28374SPTPSR from Texas Instruments is a 32-bit floating-point real-time microcontroller with a 200MHz C28x CPU, IEEE 754 FPU, Trigonometric Math Unit (TMU), and Viterbi/Complex Math Unit (VCU-II), designed for high-precision closed-loop control in industrial motor drives and solar inverters. It integrates dual-zone security, 512KB ECC-protected flash, 132KB RAM, four 16-/12-bit ADCs (up to 4.4MSPS system throughput), and 24 ePWM channels with 16 high-resolution outputs.
For engineers reviewing the TMS320F28374SPTPSR datasheet, TMS320F28374SPTPSR pinout, TMS320F28374SPTPSR application, or TMS320F28374SPTPSR equivalent, key selection criteria include its –40°C to 125°C junction temperature rating, 176-pin HLQFP (PTP) package, CLA coprocessor support, ISO 26262 ASIL B functional safety compliance, and compatibility with C2000 MotorControl and DigitalPower SDKs.
Technical Context
The TMS320F28374SPTPSR implements a single-core C28x CPU subsystem augmented by an independent 200MHz CLA coprocessor, enabling concurrent execution of time-critical control loops and background tasks. Its analog subsystem includes four ADCs configurable in 16-bit (1.1MSPS each) or 12-bit (3.5MSPS each) mode, with hardware post-processing including windowed comparators, DAC references, and SDFM integration for isolated current sensing.
Communication is supported via two CAN 2.0B modules, four SCI/UART interfaces, three SPI ports, two I²C interfaces, USB 2.0 (MAC+PHY), and a uPP parallel interface. The device uses 1.2V core and 3.3V I/O supply rails, features dual internal 10MHz oscillators, and supports multiple low-power modes with external wakeup capability.
