36氪 was informed that “Letop Technology”, a full-stack high-performance microcontroller Plus chip design manufacturer, has recently completed a Pre-A round of financing of tens of millions of yuan. This round of financing is exclusively invested by Yida Capital, and the raised funds will be used for chips. Mass production and R&D team expansion.
Established in 2020, “Leituo Technology” is a company that 36氪 continues to pay attention to. It mainly focuses on high-performance MCU (microcontroller) products, which can provide enterprises with one-stop chip solutions such as micro-control and modular custom system integrated chip (SoC, System on Chip), signal chain, BMS power management, etc. There are MCU, There are 4 product lines of PMIC (power management chip), signal conditioning chip and sensor chip.
According to the degree of integration, chips can be divided into two technical routes: system integrated chips and multi-chip combination solutions. Compared with the former, the latter has the advantage of dismantling the functions. One chip implements one or a few functions. It is usually used in fields with complex functional program requirements, but its disadvantages occupy a larger area of the circuit board and consume more power. Higher, more heat dissipation.
“Leituo Technology” chose the integration route, and its full-stack R&D capability can broaden product boundaries while saving IP licensing fees. Founder Yi Zhizhong said, “Except for the CPU core and Flash memory, all other IPs are developed by Litop Technology.” That is to say, when the downstream application market changes, Lietuo can make in-depth customization in real time according to the needs of customers.
One of the core products of “Leetuo Technology” is the CGM (Continuous Glucose Monitoring) integrated solution chip, which is such a full-stack product. It integrates functions such as ADC (analog-to-digital converter), DSP (digital signal processing), DAC (digital-to-analog converter), TIA (programmable transimpedance amplifier), temperature sensor, external communication, etc. With an integrated chip, the sensor analog signal can be converted into a digital signal for processing by the main control chip.
The SoC chips of “Leituo Technology” can also be simultaneously improved in performance and size. For example, the performance of its LTM32 series products is 25% smaller in area and 15% lower in power consumption than similar chips from the global head analog chip company STMicroelectronics. It can also compete with multi-chip solutions.
In addition, PMIC chips, another product line of “Leituo Technology”, have also achieved phased results. The products developed by it have been introduced into mass production by customers.
In terms of play style, “Leituo Technology” has laid out multiple product lines at the same time, from small to large, breaking through one by one from point to surface. In the future, “Leituo Technology” will continue to focus on 4 product lines to build full-stack MCU plus chips. In terms of downstream application scenarios, as a platform-based chip design company, “Leituo Technology” can have more possibilities to expand to other fields. After breaking through the main application scenario of medical treatment, “Leituo Technology” will also start to develop automotive-grade chips in the automotive field with higher chip reliability.
In terms of the architecture selection of SoC chips, the current products of “Leetuo Technology” are mainly based on the ARM architecture. In addition, due to the open source, flexibility, development cost and autonomous controllability of RISC-V, it has been used by more and more people. The chip design company chose, which includes the MCU chip based on the RISCV core developed by “Leituo Technology” and Suzhou Micro Five.
Investor’s point of view:
Yuan Yaguang, a partner of Yida Capital, said, “Leituo Technology is positioned as a full-stack mid-to-high-end MCU and plus chip, and is one of the few companies in China that can provide one-stop solutions. The company has a complete digital and analog chip R&D team. The core IPs are all independently developed. At present, the global MCU market has undergone structural adjustments, and some mid-to-high-end MCUs are still in short supply, and automotive-grade MCUs are the first to bear the brunt. Under the window of “domestic substitution”, Lietuo Technology is striving to catch up and explore High-end market opportunities, and actively plan for the future incremental market.”
