W562XXX
DUAL-TONE MELODY WITH
VOICE SYNTHESIZER (BandDirector
TM
Series)
GENERAL DESCRIPTION
The W562xxx is one of the derivatives of the BandDirector
TM
family. It consists of a 4-bit
μ
C, two
voice synthesizers, one Dual tone Melody generator, 38 KHz carrier output for IR transmission and
one ROM shared ROM.
The muti-tasking operation for voice synthesis and Dual Tone Melody generation is implemented by
dedicated H/W that can output the speech voice in parallel with the background music. The 4 bit
kernel, which executes instructions of up to 12 KIPS (Kilo-Instructions Per Second) can offer
customers a great deal of flexibility to achieve various kind of program controls for different
applications.
In addition, the W562xxx's user-friendly development environment can effectively reduce your design
period and help you easily tool your project by yourself with the W56xxx ICE and emulation kit.
There are 9 kinds of W562xxx IC bodies. (see table below)
