GENERAL DESCRIPTION The W561xxx is one of the derivatives of the BandDirectorTM familiy. It consists of a 4-bit µC, two voice synthesizers, one 4-track PCM-Melody generator, and one shared ROM. The muti-tasking operation for voice synthesis and 4-track PCM-Melody generation is implemented by dedicated H/W that can output the speech voice in parallel with the background music. With the 4 bit kernel, which can execute instructions of up to 12 KIPS (Kilo-Instructions Per Second), and high quality dual speaker output, you will be amazed at the possible applications. W561xxx provides you with a total solution in one chip. In addition, the W561xxx's user-friendly development environment can effectively reduce your design period and help you easily tool your projects by yourself with the ICE and emulation kit. There are 10 kinds of W561xxx IC bodies (see table below). PART NO. Duration Main ROM size PART NO.

FEATURES • Multi-engine processor parallel management with µC, speech and PCM Melody − − µC // (Synthesizer1 or 4-track PCM-Melody) // Synthesizer2 (//: in parallel) µC, with basic ALU, 64-nibble RAM (including 8 working registers) and an 8-bit timer The W561&W562 user RAM initialization value is not constant. It is random. So, user must initial constant value. − − − Synthesizer1 capable of voice syntheses with Sample rate @4.8/6/8/12 KHz Synthesizer2, same as synthesizer1 4-track PCM-Melody with total 16 Kbyte Timbre table, which can store up to 16 kinds of timbre samples. -2- W561XXX − − • • The on-chip ROM is shared among program, voices and melody notes ICE & ROM chips use different Rosc.
