General description
The MT7697 is a highly integrated single chip, which features an application processor, low power consumption 1x1. 11N single-band Wi-Fi subsystem, Bluetooth subsystem and power management unit. This application processor subsystem contains an ARM CORTEX-M4 with a 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 subsystem contains only a WiFi 802.11b/g subsystem and radio/N, baseband that are to MAC design, to satisfy both the application of low power and high throughput. It also contains a 32-bit RISC CPU that completely offloads the application processor. The Bluetooth subsystem includes the Bluetooth radio, baseband, and link controller. It also uses the same 32-bit RISC CPU for the Bluetooth protocol.

PMU Architecture
The PMU integrates 5 LDOs and a Buck converter.
The four LDOs are CLDO, ALDO, high voltage SLDO (SLDO-H) and low voltage SLDO (SLDO-L). SLDO stands for sleep mode LDO and CLDO stands for digital core LDO. Buck converter 1.6 ~ 1.8V output to other subsystems of MT7697. It can operate in PFM mode or PWM mode. Low ripple output via external on-board LC filter (2.2uH inductor and 10uF cap). 1.6~1.8V to Wi-Fi RF system, Bluetooth RF system and CLDO. CLDO is under the Buck domain, then it outputs 1.15V for the whole chip digital logic. The Aldo is also the power input from the 3.3V chip and generates 2.5V for the auxiliary ADC. The two SLDOs have output voltages of 1.8V and 0.85V, respectively. They are used to maintain the buck and CLDO output voltage while the MT7697 is in sleep mode to reduce. current consumption.
CPU
The MT7697 has an ARM CORTEX-M4 processor, which is the most energy-efficient ARM processor. available. It supports clock rates from 1MHz to 192MHz. The MCU implements the Thumb-2 instruction set for optimal performance and code size, including hardware partitioning, single-cycle multiply and bit field operations.
