GENERAL DESCRIPTION

The W536XXXP, a member of ViewTalkTM family, is a high-performance 4-bit micro-controller (uC) with built-in 8KW uC program. The 4-bit uC core contains dual clock source, 4-bit ALU, two 8-bit timers, one 14 bits divider, maximum 32 pads for input or output, 8 interrupt sources and 8-level nesting for subroutine/interrupt applications.

FEATURES

? Operating voltage: 2.4 volt ~ 5.5 volt

? Watch dog disabled/enabled by mask option

? Dual clock operating system

? Main clock with Ring/Crystal (400 KHz to 4 MHz)

? Sub-clock with 32.768 KHz RC/Crystal by mask option

? Memory

? Program ROM (P-ROM): 8 K × 20 (ROM Bank0)

? Data RAM (W-RAM): 1K × 4 bit

(RAM Bank 0 is 512 nibbles from 0: 000~0: 1FF and 0:380~0:3FF are mapped to special register. RAM Bank F is 512 nibbles from F: 200~F: 3FF either data RAM or dedicated to script kernel)

? Maximum 32 input/output pads

? Ports for input only: 12 pads (RC, RD and RG port; RG for W536090P/120P only)

? Ports for output only: 12 pads (RE, RF and RH port; RH for W536090P/120P only)

? Ports for Input/output: 8 pads
