6.2.4 CPU Memory
The memory requirements for G600 are;
1
16Mbit 3V FLASH organized as 1M * 16
2
2Mbit 3V RAM organized as 256k * 8
3
16kbit 3V Serial EEPROM as 2k * 8
6.2.5 LCD
The LCD assembly is a subassembly comprising of LCD glass and driver chip with connection to the Logic PCB.
A 96 x 58 pixel graphical display is used to give maximum information. It can also display Chinese characters and
large numbers. For example, 12 x 12 line or 16 x 3 li ne, both with 2 lines of icons.
A Sharp LH155B display driver is used.
6.2.6 Microphone
The microphone is the same type used on G500.
6.2.7 Buzzer
The volume level of the buzzer is defined by the 6 bit PWM register setting in GEMINI I/O. The buzzer tune is then
superimposed on this level using software.
Timer 1 in GEMINI is used to time the period between switching the buzzer on and off to make the tune. For more
complex buzzer ringing tunes, the buzzer volume level can also be altered after each time-out of timer 1.
