SS802X

Overview

SS802X is a special MCU development by Sinhmicro for electronic cigarettes that integrates MIC detection, heating wire resistance detection, and short-circuit protection.

Feature

  • ​​​​​​Enhanced 8-bit microcontroller compatible with the 8051 instruction set
    • Maximum frequency 12 MHz
    • Single clock instruction cycle, the performance is 8 times of the native 8051
  • Memory:8KB Code Flash (the final 32B cannot be run code. If burning 1KB each time, can be burned 8 times),192B Data RAM
  • Operation voltage: 2.7V~5.5V
  • Support one or more power supplies from adapter (VIN), battery (BAT), or VDD
  • 2 adjustable LDOs (VINLDO and BATLDO), can configure the appropriate operation voltage to other modules when VIN or BAT supplies
  • Integrated VDD low power, system overtemperature protection
  • Ultra-low power dissipation
    • Support 4 operation modes: Normal, Low-speed, IDLE, and SLEEP      
    • Power dissipation in SLEEP mode: 2μA   
    • I/O pins compared with specific levels to wake up the system 

 

  • 1 adjustable NTC
  • 12-bit 11-channel ADC
    • Supports up to 7 external inputs and 4 internal signal measurements 
    • All external input channels support configurable channel gain for current and microvoltage measurement scenarios

 

  • 2 NMOS, can be controlled by software and support linkage control with PWM, which can be applied in scenarios such as motor control
  • 2 RC oscillators
    • Low-frequency RC oscillator LORC, 32KHz
    • High-frequency RC oscillator HIRC, 12MHz
  • 1 SysTick, providing timing reference for the program
  • 1 AlwaysTimer, can wake up the system from SLEEP mode
  • 1 watchdog timer, can be used to reset when the system is timeout
  • 3* 16-bit timers  
    • Timer 0 can be used to generate PWM0 and support linkage control with Charger and NMOS
    • Timer 1 can be used to generate PWM1 and support linkage control with  ACMP, Charger and NMOS
    • Timer 2 can generate 5 PWMs with the same frequency and different duty cycles at the same time and support linkage control with Charger and NMOS

 

  • Integrated linear charger management unit with maximum 1A charge current 
    • Support 3.2V~5.5V wide voltage input, charge voltage and charge current can be finely adjusted 
    • Supports undervoltage and temperature loop functions  
    • Support linkage control with PWM 
    • Support chopper charge
  • 2 digital comparators 
  • 1 analog comparator 
    • Support linkage control with timer 1 to turn on/off
    • Support linkage control with I/O to break
    • Support e-cigarette short-circuit protection

 

  • Built-in e-cigarette MIC detection module
    • The maximum sampling range supports 100pF capacitors
    • Support MIC capacitance increasing or falling wakeup, can meet the inhalation or blow wakeup
    • Support detection of most e-cigarette airflow sensors
    • Negative pressure triggering thresholds can be flexibly configured
    • High-resolution sampling configuration, which meets the application needs of adjusting the power according to the size of the negative pressure​​​​​​​
    • Negative pressure detection conversion rates up to 50Hz​​​​​​​
  • Integrated e-cigarette heating wire resistance detection

 

  • 13 bidirectional I/O ports
    • 13 ports can be configured as Pull-Push mode or Open Drain mode
    • 5 I/Os support large current drive capability
    • Several I/Os support linkage protection with comparators to output a specific protection level when the comparator is triggered
    • The digital and analog functions of the pins can be present at the same time (for example, when the pin is high level as a GPIO output, ADC can be turned on to measure the actual voltage of the pin)
  • 1 UART, supports half-duplex communication on a single pin
  • 2-wire debug/burn interface
  • Package Type: QFN16 and DFN10
