.. W53300/W53320 16" Voice/Melody/LCD Controller (View Talk TM Series) GENERAL DESCRIPTION The W53300/W53320 are a high-performance 4-bit microcontroller (µC) with built-in speech, melody and 16- 48/32- 48 LCD driver which includes internal pump circuit. The 4-bit uc core contains dual clock source, 4-bit ALU, two 8-bit timers, one divider, 20 pin input or output, 7 interrupt sources and 8-level subroutine nesting for interrupt applications. Speech unit can be implemented with Winbond 16-sec Power Speech using ADPCM algorithm. Melody unit provides dual tone output and can store up to 1k notes. Power reduction mode is also built in to minimize power dissipation. It is ideal for games, educational toys, remote controllers, watches, clocks and other application products which incorporate both LCD display and melody. Features - Operating voltage: 2.4 volt ~ 5.5 volt - Dual clock operating system - RC/Crystal (400 KHz to 4 MHz) for main clock - 32.768 KHz crystal oscillation circuit for sub-oscillator - Memory - Program ROM: 16K× 20 - Data RAM: 512 × 4 bit (W53320), 704 × 4 bit(W53300) - LCD RAM: 384 × 4 bit (W53320), 192× 4 bit (W53300) - 20 input/output pins - Ports for input only: 2 ports/8 pins - Input/output ports: 2 ports/8 pins - Port for output only: 1 port /4 pins - Power-down mode - Hold function: no operation (except for oscillator) - Seven types of interrupts - Five internal interrupts (Divider ,Timer 0, Timer 1, Speech, Melody) - Two external interrupts (Port RC, Port RD) - One built-in 14-bit clock frequency divider circuit - Two built-in 8-bit programmable countdown timers - Timer 0: one of two internal clock frequencies (FOSC/4 or FOSC/1024) can be selected - Timer 1: built-in auto-reload function includes internal timer, external event counter from RC.0 or TONE output function (can be used as IR carrier output if main clock is 455 k Hz) - Built-in 18/14-bit watchdog timer for system reset by mask code option - Powerful instruction sets -...
