GENERAL DESCRIPTION

The W536XXXT, a member of ViewTalkTM family, is a high-performance 4-bit micro-controller (uC) with built-in speech unit, melody unit and 64seg * 32 com LCD driver unit which includes internal regulator,pump circuit and dedicated two pages LCD RAM. The 4-bit uC core contains dual clock source, 4-bit ALU, two 8-bit timers, one 14 bits divider, maximum 24 pads for input or output, 8 interrupt sources and 8-level nesting for subroutine/interrupt applications. Speech unit, integrated as a single chip with maximum 128 seconds (based on 6.4K sample rate with 5 bits MDPCM), is capable of expanding to 512 seconds speech addressed by external memory W55XXX with serial bus interface.
