(hereinafter referred to as "ReneSola"), a world-leading provider of AIoT system-on-chip (SoC) solutions, recently announced that its first low-power Bluetooth chip, RM1200, is available in volume.

 

 

 

For a long time, Nordic, Dialog and TI, representing European and American chip companies, have occupied about 90% of the multi-billion dollar annual low-power Bluetooth market. Many domestic original manufacturers can only fight in the low-end market because the key performance indicators cannot reach a certain level of requirements.

 

 

After nearly three years of refinement and polishing of the RM1200 in the power consumption level, RF performance, integration, to reach, and even some aspects beyond the level of similar products of well-known international manufacturers. Compared with the products of large overseas manufacturers, RM1200 has outstanding advantages in terms of cost to meet the needs of large-scale applications in the IoT market.

 

 

 

 

Low power consumption and high performance. With coin cell batteries can work continuously for more than two years

 

 

Due to the use of ReneSola Micro's unique "micro-watt connection system (uWLinkSystem)" low-power design, the RM1200 power consumption level performance is very eye-catching. In the case of connected state of sending and receiving data per second, the average operating current is less than 10uA; deep sleep, the operating current of 300nA. powered by a 200mA coin cell battery, the RM1200 can work continuously for more than two years under the conditions of maintaining real-time communication, power consumption performance indicators to meet the international standards of the world's leading original vendors.

 

 

Long transmission distance: actual pull distance test over a thousand meters

 

 

The RM1200's RF performance exceeds that of its international counterparts. At 125Kbps rate, the sensitivity reaches -106dBm; at 1Mbps rate, the reception sensitivity reaches -99dBm; while having a very strong anti-jamming capability. In terms of transmit power, the RM1200's maximum transmit power is 10dBm. therefore, at 1Mbps rate, the RF link gain reaches 109dB; at 125Kbps rate, the RF link gain reaches an amazing 116dB. according to the actual distance pull test, the RM1200's transmission distance exceeds 1000 meters.

 

 

High integration and low cost: only one crystal is required at the periphery

 

 

The RM1200 has an integrated charging function and LDO/DC-DC with an operating voltage of 1.8~5.5V. If the RM1200 is used in a system with a rechargeable battery, it can save the reset chip, charging chip, and LDO chip, significantly reducing the overall BOM cost and processing cost. More importantly, because of the reduced BOM, the system complexity is reduced, thus improving system reliability and reducing product defect rates.

 

 

RM1200 also in the clock stability and system robustness performance, the crystal frequency offset requirements to meet 50ppm can be, compared to the market requires the crystal frequency offset must be within 10ppm and specify the crystal manufacturer and model of the BLE chip, reducing the hidden cost of the program.

 

 

In addition, the RM1200's smallest package (QNF20) is 3mm*3mm, which is ideal for small size PCBs, and only one crystal is required for the RM1200 in the most compact circuit. The small package size, combined with the high level of integration, can help customers make previously impossible small boards possible. In addition the RM1200 series is available in a QFN32 (4mm*4mm) package to meet the needs of different application scenarios.

 

 

RM1200 advantages far beyond these, other features are also outstanding, such as: ESD of all pins exceeds 4KV (HBM), antenna port ESD performance up to 8KV; harmonic radiation intensity than the FCC standard 10 dB lower; operating temperature range: -40 ° ~ 125 °; peripheral interfaces are abundant, in addition to the common SPI, I2C, PWM, UART, UART, and other interfaces. In addition to the common SPI, I2C, PWM, UART, five-channel input GADC interface, but also support, infrared, quadrature decoder interface, digital and analog voice input.

 

 

Multi-application scenario: RM1200 can be mainly used as a replacement for similar chips from NordicnRF52 series, TI and NXP in the following application areas: smart industry, smart transportation and logistics, smart agriculture, smart buildings, smart IoT, smart medical, meta-universe, automotive electronics, positioning beacons, low-power consumer electronics, etc.

 

 

ReneSola will continue to work hard and develop in the direction of low-power consumption, to contribute to the low-carbon goals of all mankind, but also look forward to working with a common philosophy and pursuit of program companies, end-product enterprises, agents, partners together to provide society with efficient, high-energy, low-consumption wireless interconnection solutions to achieve a win-win situation for all. ReneSola Micro will provide partners with friendly and easy-to-use development tools, rapid after-sales response and full capacity guarantee.

 

 

The majority of partners should get in touch through the ReneSola Micro website (www.realmega-micro.com).

 

 

 

 

ReneSola Microelectronics Technology (Shanghai) Co., Ltd. was established at the end of 2018, located in Zhangjiang Science City, China (Shanghai) Pilot Free Trade Zone, is a high-tech enterprise focusing on the design and sales of wireless MCUs and intelligent chips in the AIOT field, and also engaged in the design and development of RF IP business.

 

 

The company's R&D team is formed by a group of domestic and foreign first-class experts with 20 years of product experience, with a complete variety of short-range wireless communication technology, as well as rich experience in audio signal processing, with a variety of billions of chips mass production experience.

 

 

The company's main business currently has two major blocks: first, the design of AIoT chip products, the company is developing ultra-low power wireless interface (BLE and WiFi6) MCU system chips; second, RF analog IP commissioning design business, mainly based on CMOS advanced process of various IP commissioning design and consulting. Many IPs have been mass-produced, and these IPs have been well received and respected by industry users because of their excellent performance, easy operability, extremely low cost, and mature and reliable stability.

 

 

The future goal of ReneSola Microelectronics is to deeply cultivate artificial intelligence, smart audio, smart home, wearable devices, smart medical and other fields to create a complete chip-level signal chain system (sensor - wireless transmission - signal processing and output) to provide customers with highly integrated high-performance low-cost, stable and secure system solution chips for wireless interconnection and edge computing and audio processing.
