SS881X is Sinhmicro's AD Flash MCU series with integrated charge and discharge managementbuilt-in rich interface functions, flexible configuration modes, and different low power consumption options. This product is mainly used in portable intelligent electronic devices that require charging and intelligent control, bringing simplified peripheral costs, excellent performance,and flexible and convenient development.
SS881X has built-in 8-bit MCU compatible with 8051 instruction set, the highest frequency is12MHz. After optimization, most 1-byte instructions can be executed in a single clock cycle. Built-in 192 bytes of RAM are used for data caching, 8K bytes of Flash support multiple code updates,and 128 bytes of EEPROM are used to save special user information.
Ss881X also integrates a power management unit and a charging management unit. Supports battery or 5V adapter power supply, supports charging of batteries with different specifications and different capacities, provides full software real-time configurable charging voltage and currentsettings, and combines built-in detection and protection mechanisms such as undervoltage,overvoltage, overcurrent, and overtemperature, Can provide efficient and safe power solutions.it supports 5 working modes: normal, low speed, idle, standby and hibernation. While providing high performance, it provides a variety of low power consumption options to support battery-powered devices and scenarios. The typical power consumption in sleep mode is 3uA, and the typical power consumption in standby mode is 30uA.
ss881X contains a wealth of peripherals, up to 16 bidirectional 1/ 0 ports (Ss8819 only 12 1 / 0),some 1 / O support high current constant current drive, 2 external interrupt EINT0 / 1, 12-bit 8-channel differential ADC, 2 analog comparators, 1 UART, 1 I2C, 1 SCOM interface for driving and controlling the broken code display, 1 serial distribution port supporting cascade control， 1 programmable frequency output unit, 1 debugging interface for debugging and programming
SS881X has a built-in 16-bit timer / counter. These two timers / counters can independently output two PWM signals With adjustable cycle and duty cycle (can be configured as a breathing lamp mode automatically controlled by hardware). It also contains a 13-bit timer, supports automatic reload,supports up to 4 comparison outputs or capture inputs, and can simultaneously output 4 PWM signals with the same frequency and different duty cycles. These 4 PWM signals can support higher precision duty cycle mode.
Typical application scenarios of Ss881X series chips: smart TWS earphone charging cabin, smart personal care equipment, smart portable electrical appliances.
