TMS320F28374DZWTS

Microcontrollers Overview

The TMS320F28374DZWTS is a 32-bit dual-core microcontroller from the Texas Instruments C2000 Delfino family. It features two C28x CPUs operating at 200MHz, equipped with IEEE 754 single-precision floating-point units (FPU), trigonometric math units (TMU), and Viterbi/complex math units (VCU-II). The device includes two programmable Control Law Accelerators (CLAs) running independently at 200MHz. Memory consists of 512KB flash with ECC protection and 86KB RAM with ECC or parity protection. It integrates four 16-bit ADCs, six DMA controllers, up to 169 GPIOs, USB 2.0, CAN, SPI, I2C, SCI, and uPP interfaces in a 337-NFBGA package.

Microcontrollers Feature Summary

• Dual-core architecture with two independent 200MHz C28x CPUs for high-performance real-time control
• Integrated hardware accelerators including TMU, VCU-II, and FPU for complex mathematical computations
• Two programmable Control Law Accelerators (CLAs) that execute code independently of the main CPU
• Advanced analog subsystem with four 16-bit ADCs and hardware-integrated post-processing capabilities

Microcontrollers Applications

• Industrial motor drives and servo systems
• Photovoltaic inverters and digital power supplies
• Electric vehicle and transportation control systems
• High-speed signal processing and sensing applications

Microcontrollers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for specific PCN notices regarding design changes or wafer fab site updates. Ensure the package marking matches the official datasheet specifications to avoid counterfeit risks during integration.

Microcontrollers Selection Notes

Select this model when dual-core processing isolation and functional safety requirements are necessary. The inclusion of CLAs allows offloading time-critical control loops from the main CPU. Verify that the 512KB flash capacity meets application code storage needs and that the NFBGA package fits the PCB layout constraints compared to QFP alternatives.

Microcontrollers Part Context

This part belongs to the TMS320F2837xD series, which defines the dual-core variant of the Delfino microcontrollers. It shares architectural similarities with other members like the TMS320F28377D but differs in memory size and pin count. The 'ZWT' suffix indicates the 337-NFBGA package type, while 'S' denotes the commercial temperature range extension.

Microcontrollers Replacement Considerations

The TMS320F28377DZWTS serves as a verified substitute within the same package offering higher memory capacity. For single-core requirements, the TMS320F28374SPZPS provides comparable core performance in a different package format.
