Hi2825V100

Hi2825V100 is a highly integrated 2.4 GHz BLE/SLE combo SoC. It comes equipped with high-performance, ultra-low-power BLE 5.3, SLE 1.0, and RF circuits. The RF circuit consists of the power amplifier (PA), low noise amplifier (LNA), antenna, and power supply management modules. NearLink Low Energy (SLE) supports three bandwidths: 1 Mbps, 2 Mbps, and 4 Mbps. The maximum rate at the physical layer is 12 Mbps. Hi2825V100 also integrates a high-performance 32-bit microprocessor (MCU) and a large-capacity SRAM and flash memory. It allows programs to run in flash memory and comes with a hardware security engine.
Hi2825V100 has a wide range of peripheral interfaces – USB2.0 High Speed, SPI, UART, I2C, PWM, GPIO, PDM, I2S/PCM, and supports the 8-channel 12-bit 4Msps SAR ADC and 1-channel 16-bit 1Msps SAR ADC (high performance).
Hi2825V100 supports LiteOS and FreeRTOS. The complete set of user manuals, open and easy-to-use software SDKs and tools, and detailed hardware reference design – all are provided to create an enjoyable experience with the product.
Hi2825V100 can be used in many different HID peripherals such as VR controllers, e-competition keyboards, mouse devices, and stylus, and consumer electronics such as PCs, tablets, TVs, and STBs.

NearLink Connectivity

Ultra-low delay air interfaces for an ultimate experience

With a novel physical layer, NearLink SLE smaller timeslots leading to greatly reduced end-to-end latency. Its polar code–based channel coding delivers over 7 dB coverage gains and anti-interference capabilities. It allocate resource based on center scheduling and uses an innovative channel scanning and selection mechanism, delivering fast frequency hopping and optimal channel selection, bringing great leaps in connectivity stability and transmission reliability. NearLink SLE also supports higher bandwidth and higher-order modulation to offer much much higher transmission speed.

BLE+SLE+USB 3-in-1

Flexible connectivity to support peripherals

NearLink SLE + USB 2.0 High Speed enable up to 8 KHz wired performance. The support for BLE 5.3 enables massive Bluetooth applications. With a 16-bit high-precision SAR ADC built-in, the product also provides oversampling and automatic calibration, and it can be used to collect various physical data, including pressure and environmental parameters.
