TMS320F28P55x MCU: Powering the Next-Gen EV Market
TMS320F28P55x Microcontroller Chips Drive Upgrades in the New Energy Vehicle Market
From late 2024 to early 2025, Texas Instruments (TI) officially released the TMS320F28P55x series of real-time microcontroller chips. Since its release, demand for this series in the new energy electric drive market has rapidly increased, with sales increasing by over 20% year-over-year. Its outstanding real-time performance and automotive-grade reliability have made it the preferred choice for automakers and Tier 1 suppliers. As an electronic component trader, Kingrole recommends the most suitable microcontroller chip model based on the customer's vehicle platform, power range, and cost requirements, helping them reduce system costs and shorten development cycles.
Microcontroller Chip: Meets Automotive-Grade Reliability
The TMS320F28P55x meets AEC-Q100 automotive standards and operates in temperatures ranging from -40°C to 125°C, making it suitable for harsh automotive environments. Built-in ECC checksum and safe boot mechanisms ensure the stability of the electric drive control system even at high speeds.
Microcontroller Chips: Analysis of Popular Models and Their Functions
In new energy vehicle applications, the F28P550Q and F28P552R are the most popular models. The former is suitable for single-motor platforms, while the latter supports multi-motor control, features more high-resolution PWM and ADC channels, and enables synchronized three-phase drive and current sampling.
Microcontroller Chips: Practical Application Examples
Taking BYD as an example, its latest generation 800V SiC electric drive system uses the F28P550Q controller, combined with TI's MotorWare control algorithm, to achieve 20kHz high-frequency PWM drive, improving the electric drive system efficiency by 3%. Ideal Auto uses the F28P552R for coordinated control of its front and rear motors, improving vehicle energy recovery efficiency.
Microcontroller Chips: Pricing and Supply Chain
In the second quarter of 2025, the high-volume purchase price of the automotive-grade F28P550Q will remain between US$8.0 and US$8.5, with a lead time of approximately 12 weeks. Thanks to the recovery of global wafer foundry capacity, supply stability has significantly improved. Through Kingrole, automotive customers can obtain genuine, authorized microcontroller chips from the original manufacturer and lock in long-term supply agreements, reducing the risk of stockouts.
Microcontroller Chip: Comparison with Competitive Products
Compared with the Infineon TC3xx series, the F28P55x offers advantages in unit cost and development ecosystem. Compared with the Renesas RH850 series, the F28P55x offers a more comprehensive motor control library, enabling rapid implementation of dual closed-loop torque and speed control, reducing development workload.
Microcontroller Chips: Trader Purchasing Recommendations
For new energy vehicle customers, we recommend planning production capacity needs in advance and targeting popular models, especially the F28P550Q. Kingrole can provide BOM optimization, volume discounts, and on-site technical support to help customers reduce development and production costs.
