1. Description
AcSiP Technology Corp. introduces a low-cost and low-power consumption IoT module. This
stand-alone module is an operating system designed for wearable or internet of things (IoT) devices
with smart connection and cloud application/services.
AI7687H is a highly integrated SIP module which features an application processor, a low power 1x1
11n single-band Wi-Fi subsystem, a Bluetooth subsystem, and a Power Management Unit. The
application processor subsystem contains an ARM Cortex-M4F MCU, which has many peripherals,
including UART, I2C, SPI, I2S, PWM, IrDA, and auxiliary ADC. AI7687H also includes embedded
SRAM/ROM and a SPI 2MB serial flash.
The Wi-Fi subsystem contains the 802.11b/g/n radio, baseband, and MAC that are designed to meet
both the low power and high throughput application. It also contains a 32-bit RISC CPU that could
fully offload the application processor.
