SS885X

Overview

SS885X is a low-power MCU that integrates touch detection and 5V carrier communication functions. The chip has built-in rich interface functions, flexible configuration modes and different low-power options, mainly used in TWS Bluetooth headsets, providing functions such as communication with the charge cabin, in-ear detection, and touch detection in the form of a coprocessor.

Feature

- 8-bit enhanced MCU，8KB Flash，256B RAM，128B EEPROM

- Battery or 5V adapter power supply

- VIN supplies through VOUT after the OVP module      (which supports withstand voltage up to 14V)

- supports bidirectional carrier communication, which can modulate data to the power supply signal for synchronous transmission

- Integrated input overvoltage, overcurrent, VDD low power, system overtemperature protection

- Ultra-low power consumption with as low as 0.8μA in SLEEP mode and 10μA in STOP mode. Normal mode is 500μA

- Integrated a 5-channel capacitive touch sensor, supports in-ear detection and touch buttons

- Integrated 1 hardware trigger module can output a specified level or pulse on the Trigger pin when the chip is in any operation mode, timing or the input level of VIN pin changes
