In anticipation of the Auto Show, showcasing core products | YTMicro launches the new "Z" series dedicated micro-motor SoC.

Recently, Jiangsu Yuntu Microelectronics Co., Ltd. (YTMicro for short) has made another significant breakthrough with the successful launch of the new "Z" series dedicated micro-motor SoC. Prior to this, YTMicro had already achieved mass production of 15 chip models from the YTM32B1L and YTM32B1M series. The introduction of the YTM32Z series marks a key step in YTMicro's development of a complete portfolio of automotive-grade products, featuring both "general-purpose MCUs + dedicated SoCs."

According to research data from the China Automotive Chip Industry Alliance, the market shortage for automotive micro-motor dedicated chips is even more severe than that for general-purpose MCUs. Leveraging YTMicro's expertise and long-term experience in automotive-grade chip development, we are proud to introduce the Z series micro-motor dedicated SoC to the market. This will greatly address the current shortage of micro-motor chips and further contribute to the stability of the domestic chip supply chain.

The YTM32Z series is a highly integrated, dedicated SoC chip developed by YTMicro for automotive applications, specifically for DC brushless (BLDC) motors and stepper motors. The YTM32Z series integrates a power management module, LIN transceiver, and four pairs of high and low side pre-drivers on a single chip, enabling it to drive a DC brushless motor or stepper motor with just one chip. This significantly simplifies the motor driver board structure, reduces PCB area, and enhances both stability and reliability, while effectively lowering costs.

Product Features and Advantages:

· Cortex M0+ 32-bit ARM processor, with a maximum clock speed of 48MHz, compatible with ARM compilation and debugging toolchain

· Integrated EEPROM

· Supports operating voltage of 5.5 ~ 28V, supports HVIO input

· Operating temperature range from -40°C to 175°C

· Integrated LDO, 4 high-side drivers, 4 low-side drivers

· Integrated LIN-PHY

· Built-in common motor drive algorithms

· 1MSPS 10-bit ADC, supports 16-channel internal signal sampling and 8-channel external sampling, supports internal temperature sensor sampling

· Integrated sampling resistor op-amp, supports single-resistor sampling

The YTM32Z series has an operating temperature range of -40°C to 150°C, with a junction temperature up to 175°C. It is widely applicable in automotive micro-motor applications such as water pumps, oil pumps, air conditioning compressors, air conditioning blower motors, electronic rearview mirrors, and anti-pinch window motors.

Compared to general-purpose MCUs, YTMicro's Z series products, with their highly integrated compact solutions, significantly reduce design workload while offering the required functionality at a lower BOM cost. At the same time, the number of dedicated SoC peripherals and memory size in the Z series are optimally configured for specific applications, effectively minimizing resource waste.

YTMicro Z Series Promotes the Intelligent Development of Domestic Automotive Industry

From general-purpose MCUs to the Z series micro-motor dedicated SoCs, YTMicro's products have continuously achieved leaps in chip performance and upgrades in product portfolio. YTMicro is making significant contributions to chip localization and the security of the automotive industry supply chain.

Due to the high integration and design complexity of automotive micro-motor SoC chips, as well as limited special process capacity, market research shows that automotive micro-motor SoC chips will remain in severe shortage until mid-2024. The successful launch of YTMicro's Z series will greatly alleviate the shortage of automotive micro-motor SoC chips in the domestic market and further accelerate the widespread adoption of intelligent electric vehicles.

At the same time as launching the Z series dedicated micro-motor SoCs, YTMicro's H series high-performance multi-core products, which meet functional safety ASIL-D requirements, have also completed tape-out and are expected to be released to the market in Q3 of this year. YTMicro's four major product series—YTM32B1L, YTM32B1M, YTM32B1H, and YTM32Z—will gradually cover 90% of the application functions across the five major vehicle domains.

YTMicro's Service Advantages as a Domestic Chip Manufacturer

Against the backdrop of supply chain security, YTMicro's domestic service advantages have become increasingly prominent. The automotive industry is placing more emphasis on the autonomy and control of the supply chain, making supply chain security the top priority for OEMs and Tier 1 suppliers when selecting domestic automotive-grade chips. This has also created an opportunity for the domestic substitution of automotive-grade chips.

In this context, YTMicro chips have become the first choice for many OEMs and component manufacturers looking for domestic chip solutions. Through its localized supply chain service system, YTMicro continuously enhances its risk resilience, flexibly allocates resources, shortens R&D cycles, and reduces development costs.

In addition, YTMicro, as a domestic chip company, offers strong local technical service support. With customer needs as the top priority, YTMicro provides in-depth product development assistance. Through close collaboration and alignment with customer requirements, YTMicro is able to continuously meet the evolving needs for automotive intelligence and connectivity.
