w562xxx dual-tone melody with voice synthesizer (banddirector tm series) publication release date: fabruary 1999 - 1 - revision a2 general description the w562xxx is one of the derivatives of the banddirector tm family. it consists of a 4-bit 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.
