W536030P

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. 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. It can be implemented with Winbond Power Speech using MDPCM 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 educational toys, remote controllers and other application products which incorporate both melody and speech
