GENERAL DESCRIPTION
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. Besides, Vlcd has excellent voltage variation when Vdd changes from 2.4V to 3.6V. Further more, ST2602B has inside trimming fuse function for Vlcd and LVD.So every ST2602B real-chip will have almost the same default Vlcd and LVD voltage. The ST2602B equips 2 serial communication ports, one UART port and one SPI port, 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 ST2602B 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 designi……
