On February 9, 2022, at the beginning of the Chinese New Year, Jerry Technology officially released the second generation smart watch chip - JL7012A. Based on the first generation watch, Jerry carefully listened to market feedback and continuously upgraded and optimized his own products. Compared to the first generation chip, JL7012A significantly improves the chip's processing power, RF performance, screen display effect, peripheral interfaces, and overall battery life of the solution. The JL7012A, tailored for mid to high-end smartwatches, is a dual mode SoC that supports Bluetooth 5.3. It has a dual core 32bit 192MHz CPU, 640KB SRAM, and 16Mb FLASH, audio encoding and decoding module, image hardware acceleration module, as well as SDIO, high-speed USB2.0, QSPI, IIC, UART serial port, low-power Sensorhub, and other interfaces, allowing for flexible access to peripheral devices such as heart rate, blood oxygen, and G-sensors.
The second generation smart watch chip JL7012A has the following obvious advantages:
1、 5.3 Dual mode Bluetooth single chip, highly integrated chip
At present, most of the Bluetooth call watches on the market are equipped with a BLE chip and a Bluetooth audio 3.0 chip. This dual chip solution will result in a particularly large number of peripheral devices and a very high overall cost, which lacks competitiveness in the market. JL7012A supports Bluetooth BLE and Bluetooth audio to work simultaneously or independently; At the same time, it also has built-in modules such as PMU, Flash, RAM, and a variety of peripherals, making the periphery very streamlined. This will greatly improve the production yield of finished products and leave more room for small-scale smart watches to play.
2、 Supports high-resolution screens with a refresh rate of 480 * 480 @ 60Hz
JL7012A has strong computing and processing capabilities, with a 32-bit dual core CPU, each with a main frequency of up to 192MHz. It is equipped with a built-in 640+32KB SRAM and image hardware acceleration module, as well as a 4-channel 96MHz QSPI and 8080 interface; Swiping the screen can achieve a refresh rate of 480 * 480 @ 60Hz, and can achieve UI effects such as cropping, scaling, rotation, and translucency. Fingers can quickly drag without tearing sensation. If you want to achieve better screen brushing effect, JL7012A also supports expanding PSAM with larger data capacity.
3、 Ultra low power standby
JL7012A inherits the low-power advantage of Jerry Bluetooth earphones, which greatly reduces power consumption while ensuring screen brushing effect. In terms of standby power consumption, BLE maintains a connection of about 100uA; BR maintains a connection of approximately 200uA, while BR+BLE simultaneously connects approximately 200uA; The soft shutdown running time is about 15uA. In terms of working power consumption, Bluetooth audio playback is 5mA, Bluetooth call is 6mA, and local audio playback is 10mA; At the same time, the chip also features a low-power Sensorhub, which can greatly increase the overall battery life of the watch.
4、 Bluetooth call+Bluetooth audio playback
JL7012A is a dual mode Bluetooth chip that supports 16KHz MSBC high-definition Bluetooth calls. You can make phone calls through a smartwatch and play mobile music through Bluetooth. In order to enable the small smartwatch to achieve high-definition calls and play beautiful songs, the chip is also equipped with high-performance DAC and ADC. Echo cancellation and DNS neural network deep call noise reduction algorithms are added to the calls, supporting single/double label ENC.
5、 Local audio playback+push songs to TWS Bluetooth headphones
The JL7012A has a built-in 24bit high-performance stereo audio encoding and decoding module. When disconnected from the phone, the watch can play songs from the TF card/SD nand, which supports up to 256GB and can store a large amount of songs. JL7012A also supports Bluetooth host mode and can connect various Bluetooth audio devices to play smartwatch music (such as TWS Bluetooth headphones, Bluetooth speakers, etc.).
6、 Support Alipay/WeChat dual payment
Alipay/WeChat dual payment mode, no cash payment, no need to search the wallet, just raise your wrist for shopping settlement, fast and safe, save time and worry, even if there is no network, it can also pay, at the same time, it is also an access card, traffic card, covering nearly 300 cities in the country, subway/bus, no need to manually switch, smart card swiping, more convenient travel.
7、 Superior audio performance and Bluetooth RF performance
JL7012 A not only has low power consumption and high screen refresh rate, but also has excellent Bluetooth and audio performance indicators. Bluetooth reception sensitivity -96dBm, transmission power 10dBm; The DAC signal-to-noise ratio can reach 105dB, with an absolute noise level of 4UV, and the ADC signal-to-noise ratio can reach 95dB. In order to achieve better auditory effects, the JL7012A supports flexible adjustment of the EQ curve.
8、 Voice interruption wake-up, voice control equipment
JL7012A supports self-developed or third-party voice interruption wake-up algorithms, and supports two modes: offline voice wake-up and online voice wake-up; Can independently define command words and wake-up words, and support voice assistant wake-up words for all mobile phones; You can control the device through voice, whether it's playing songs up and down, pausing, making and answering calls through voice, or navigating maps, all of which can be controlled through voice.
9、 Diversified functions
JL7012A has very powerful functions. In addition to the above, it can also achieve Bluetooth call recording, local environment recording, mini game applications, and more.
