GENERAL DESCRIPTION
small internal display RAM as the buffer of large-sized display. User may free major internal RAM for computing or temporary access while keeping the display content. The clock of LCD (LCDCK) is not only sourced from main-frequency (OSC), it can also be sourced by OSCX (32KHz crystal) to make current consumption to be minimum. The ST2608B equips serial communication ports, one UART and one SPI, to perform different communications, ex.: RS-232 and IrDA, with system components or other products such as PC, Notebook, and popular PDA. Three clocking outputs can produce synthesized PWM signals or high frequency carrier for IR remote control. This helps products become more useful in our daily life. The built-in four-channel PSG are designed to generate key tone, melody, voice, and speech. Two dedicated pins with large driving capacity can drive a buzzer/speaker directly. The ST2608B has a Low Voltage Detector (LVD) for power management usage. The status of internal or external power can be detected and reported to the management software. Power bouncing during power-on is a major problem when designing a reliable system. The ST2608B equips a Low Voltage Reset function to keep the whole syst……
