Description

Features:

· Dual-channel operation via interrupt for automatic voice segment concatenation
· Multi-engine processor, which is composed of
   1) mC, with basic ALU, 64-nibble RAM, and 8-bit timer.
   2) Synth1, capable of voice syntheses with 4-bit ADPCM
       @SR=4.8/6/8/12 Khz and 8-bit PCM @SR=3/4/6 Khz.
   3) Synth2, same as synth1.
   4) PCM Melody (4-tone melody) and voice melody are possible with 16 Kbyte timbre ROM.
   5) The on-chip ROM is divided into two memory spaces: the main ROM is
       shared among program execution, voice synthesis, and note storage;
       the timbre ROM is used to store the PCM data of timbre.
· Multi-tasking (+: in cascade, //: in parallel)
   à mC // (synth1 + PCM Melody) // synth2
· Dynamic register control by LD instructions
   à Volume (VOL1/VOL2 for channel 1/2)
   à Melody: timbre0/1/2/3, tempo
· PCM Melody (W561xxx only)
   à melody synthesis
   à Note number only limited by main ROM size
   à Note span: G1 - G5 (G3 as timbre, 49 notes, 4 octaves). G2 - G6, provided G4 as timbre.
   à 4 kind of envelope control in 16 steps
   à User-definable timbre library to achieve various kind of instrument effects
   à Midi-conversion utility provided
· Selectable PCM Melody quality (SR=12 KHz, 1key/timbre)
   à Table size: 1/2/3/4/6/8/12/16 Kbyte per timbre.
   à Loop size: 128/256/512/1K/2K/4Kbit with respect to table size.
· Low power consumption (@5 volt)
   à < 1 uA @standby
   à < 1 mA @operation, no load (Ring oscillator)
   à < 100 mA @operation with one SPK connected
· Operating voltage: 2.4 - 5.5 volt
· Truely interrupt, instead of polling
· TG interrupt provided
   à Shared TG interrupt for P0/P1 inputs
   à Global TG interrupt enable (IEF.3) provided
   à Individual interrupt enable (PER0/PER1) provided
· 1 input port (P0), 2 I/O ports (P1 & P2), & 1 output port (P3)
· 8-level STACK shared by CALL, timer, synthesis, and TG.

Description

The W561xxx is a sub-set of the W56000. It consists of a 4-bit uC, two ADPCM/PCM synthesizer and one PCM Melody generator. The W562xx also consists of 4 bits uC, two ADPCM synthesizer and one dual tone melody generator but PCM Melody generator for cost issue, and do not support volume control. The internal 4-bit uC is composed of a 64-nibble RAM, and an 8-bit timer.

The W561xxx is one of the derivatives of the W56000 family (the MIDI speech products with multi-engine capability). It is capable of processing mC, speech synthesis, and PCM Melody generation in parallel. The internal 4-bit mC is a simple engine to execute instructions of up to 12 KIPS (Kilo-Instructions Per Second). Other engines are activated in parallel with the mC to implement specific tasks, like speech syntheses and PCM Melody generation.

The W561xxx consists of a 4-bit mC, two ADPCM/PCM synthesizers, one 4-tone PCM Melody generator, and on-chip ROM (program ROM plus 128-Kbit timbre ROM). The internal 4-bit mC is composed of an ALU, a 64-nibble RAM, and an 8-bit timer.

The dual channel operations (synth1 and synth2, or synth and PCM Melody) is implemented by dedicated H/W only with the help of synth interrupts for concatenating voice segments and melody phrases automatically. The efforts in programming the speech equation is much like that of the PowerSpeech. User-friendly programming style is thus preserved under Winbond's speech coding system.

The W561xxx is equipped with the W56000 ICE system, customers' programs can be debugged efficiently and effectively than ever.
