Product details
Overview
TMS320F28376SPTPS 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), supporting up to 1MB flash and 164KB RAM. It integrates four 16-/12-bit ADCs (1.1MSPS/3.5MSPS), 24 ePWM channels (16 HRPWM), dual CAN, USB 2.0, and CLA coprocessor - deployed in EV traction inverters, solar string inverters, and industrial motor drives.
For engineers reviewing the TMS320F28376SPTPS datasheet, TMS320F28376SPTPS pinout, TMS320F28376SPTPS application, or TMS320F28376SPTPS equivalent, key selection criteria include its single-CPU/CLA architecture (vs. dual-core F2837xD), –40°C to 125°C junction temperature rating, 176-pin HLQFP package with PowerPAD™ thermal enhancement, and functional safety compliance up to ASIL B/SIL 2.
Technical Context
The TMS320F28376SPTPS implements a single-C28x CPU + CLA subsystem (200MHz each), where the CLA executes time-critical control loops independently of the main CPU using IEEE 754 floating-point instructions. Its analog subsystem includes four independent ADCs with differential/single-ended input modes, hardware post-processing (windowed comparators, DAC-referenced thresholds), and SDFM for isolated shunt current sensing.
Control peripherals feature 24 ePWM channels with dead-band generation on both standard and high-resolution outputs, six eCAP modules, three eQEP interfaces, and eight SDFM input channels. Communications include two ISO 11898-1-compliant CAN modules, four SCI/UART ports, three SPIs, two I²C, one USB 2.0 (MAC+PHY), and a uPP interface for FPGA co-processing.
