Part No.	W536E3A0
Datasheet	N/A
Description	The W536xxx0 is a high-performance 4-bit micro-controller (µC) with built-in speech and 64seg * 16 com LCD driver which includes internal pump circuit. The 4-bit µC core contains dual clock source, 4-bit ALU, two 8-bit timers, one divider, max 1 2 pin input or output, 5 interrupt sources and 8-level subroutine nesting for interrupt applications. 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 speech.
Features	Operating voltage: 2.4 volt ~ 5.5 volt Dual clock operating system - Main clock with Ring/Crystal (400 KHz to 4 MHz) - sub-clock with RC/Crystal ( 32.768 KHz ) Memory - Program ROM: 32K x 20 bit - Data RAM: 1.4K x 4 bit - LCD RAM: 256 x 4 bit x 2 pages Input only: 4 pi ns (RC port); I/O ports: 8 pins (RA , RB port) One built-in 14-bit clock frequency divider circuit Two built-in 8-bit programmable countdown timers Built-in 18/14-bit watchdog timer MFP output: modulating or non - modulating frequency output . 8-level subroutine (including interrupt) nesting LCD driver output 64 seg x 16 com - 1/4, 1/8 or 1/16 duty, 1/3, 1/4 or 1/5 bias - internal pump circuit option by special register - SEG /COM shared IO Direct driving speaker/buzzer or PWM output
