GENERAL DESCRIPTION
Speech unit, integrated as a single chip with maximum 32 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. 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 that incorporate both LCD display and speech. Voice PART NO I/O pad WDT disable/Enable (Mask Option) Sub-clock RC/XTAL mode (Mask Option) RD port shared as serial bus (Mask Option) Tri-state serial bus (Mask Option) (3) Cascaded Voice ROM through serial bus (2) W536A031 30 sec 8I/O, 8I (RA/RB/RC/RD) Y Y Y (1) Y N Notes: 1. Share 3 pads of RD port (RD1/ADDR, RD2/DATA and RD3/CLK) 2. Dedicate serial bus 3 pads (ADDR, DATA and CLK) to interface with W55XXX. Cascaded Voice ROM can help to expand voice up to 512 sec by W55XXX chip.
