     FH511 In order to EPROM As memory 8 Bit microcontroller , Designed for many IO Designed for the application of the product , For example, remote control 、 Fan / Lighting control or around the amusement device, etc . Adopt CMOS Process and provide customers with low cost 、 Significant advantages such as high performance .FH511 The core is based on RISC The reduced instruction set architecture can be easily edited and controlled , share 55 Orders . Except for a few instructions, you need 2 Time series , Most instructions are 1 A sequence can complete , It allows users to easily complete different applications with program control . Therefore, it is very suitable for all kinds of low and medium memory capacity but complex applications .

      FH511 stay I/O In terms of resources ,FH511 Yes 6 The root is elastic in both directions I/O Foot , Every I/O Each pin has a separate register to control the input or output pin . And every one of them I/O The pins have additional program control functions, such as pulling or pulling down the resistance or opening the drain (Open-Drain) Output . In addition, for infrared remote control products ,FH511 Built in infrared carrier transmitter with selectable frequency .

     FH511 There are two sets of timers , The system frequency can be used as a general timing application or triggered from an external signal . in addition FH511 Provide 1 Group 8 Bit resolution PWM Output or buzzer output , It can be used to drive the motor 、LED、 Or buzzer, etc .

    FH511 Dual clock mechanism is adopted , Both high-speed oscillation and low-speed oscillation are controlled by the internal RC Oscillation input . Under the dual clock mechanism ,FH511 Multiple working modes can be selected, such as normal mode (Normal)、 Slow mode (Slow mode)、 Standby mode (Standby mode) And sleep patterns (Halt mode) It can save power consumption and prolong battery life . And the microcontroller is using internal RC When oscillating at high speed , The low-speed oscillation can use the external accurate vibration at the same time Crystal 32768Hz To time . It can maintain high-speed processing and accurately calculate the real time .

     FH511 In power saving mode, such as standby mode (Standby mode) And sleep patterns (Halt mode) in , There are a variety of events that can trigger interrupt wakeup NY8A051G Enter normal operation mode (Normal) or Slow mode (Slow mode) To deal with emergencies .

     FH511 Built in low-speed crystal oscillator (32768Hz) Capacitance ,CL Yes Disable、7pF、9pF、12.5pF Four options are available , Convenient for customers to reduce external parts , More accurate PPM value .
FH511 stay PB0/PB1/PB2 The built-in large driving current mode can reach a maximum of ([email protected],[email protected]/VOH=4V,[email protected], [email protected]/VOL=1V), Provide customers with high current demand . And in PB3(VPP) Increase the internal pull-up resistance 85K Ohm , And the switch can be controlled by program .
