System Overview

1.1

General Description

MT7697D is a highly integrated single chip which features an application processor, a low power 1x1

11n dual-band Wi-Fi subsystem, a Bluetooth subsystem, and a Power Management Unit. The

application processor subsystem contains an ARM Cortex-M4 with floating point MCU. It also

includes many peripherals, including UART, I2C, SPI, I2S, PWM, IrDA, and auxiliary ADC. It also

includes embedded SRAM/ROM .

The Wi-Fi subsystem contains the 802.11a/b/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.

The Bluetooth subsystem contains the Bluetooth radio, baseband, link controller. It also uses the

same 32-bit RISC CPU for the Bluetooth protocols.
