7 | VDD | PWR | Power supply internal power regulator, (2.5V~3.2V) supply VDDA
(1.9V) is the power supply regulator output.
Power supply voltage low power operation (1.73V~1.94V) |
8 | AVDD | PWR | Power supply for analog/digital circuit (1.8V)
Power supply voltage low power operation (1.73V~1.94V) |
Features of wireless mouse chip:
1. Single power supply, power supply range: 1.7V to 3.2V
2. Precise optical displacement prediction technology
3. Very good 2-D motion sensor
4. Support extremely fast movement speed
5. Maximum movement speed: 28 inches/sec
6. CPI up to 1600
7. Once you are not exercising, immediately enter the energy-saving mode
8. Data transmission is realized through serial interface
9. Built-in low-power timer (LPT), there are two modes of sleep1/sleep2
10. The mouse can be waked up by the MOTSWK pin, and the sensor can wake up from sleep mode
11. LED current-limiting resistance: 68 ohms -470 ohms (depending on the actual solution to determine the resistance), recommended: 100 ohms
specification:
Power supply operating voltage: 1.73V ~ 1.94V (VDD and AVDD short) 2.2V ~ 3.2V (VDD) Optical lens: 1:1 Speed: 28 inches/sec CPI: 400/ 500/ 600/ 800/ 1000(Default)/ 1200/ 1600 CPI frame rate: 3000 frames/sec. Typical operating current:
2mA @mouse movement (normal)
300uA @Mouse does not move (Sleep1)
60uA @Mouse does not move (Sleep2)
7uA @power down mode
SPI interface register reading and writing:
Registers in the address segment 0X00~0X0E can be directly read and written;
Read and write registers in the 0X10~0X7F address segment must first open the read and write protection registers, that is, configure the following two registers (generally not used in applications)
Write 0X5A to 0X09;
Write 0X9A to 0X5B.
There is an oscillator with a frequency of about 24Mhz inside the V108, which can be selected through the configuration register. The specific configuration is as follows: first turn on write protection
Reg0X51 = 0x0B is to select external resistance, Reg0X51 = 0x09 is to select internal resistance,
Reg0X53 is the internal resistance adjustment register. When Reg0X53=0x00, the frequency is the highest, and when Reg0X53=0x7f, the frequency is the lowest. The default value Reg0X53=0x48.
