Description

Features:

· Multi-engine processor parallel management with mC, speech and PCM Melody
   - mC // (Synthesizer1 or 4-CH Melody) // Synthesizer2 (//: in parallel)
   - mC, with basic ALU, 64-nibble RAM (including 8 working registers) and an 8-bit timer
   - Synthesizer1 capable of voice syntheses with Sample rate @4.8/6/8/12 KHz
   - Synthesizer2, same as synthesizer1
   - 4-CH Melody with total 16 Kbyte Timbre table, which can store up to 16 kinds of timbre samples.
   - The on-chip ROM is shared among program, voices and melody notes
· Wide operating voltage range: 2.4 to 5.5 volts
· Low power consumption (VDD = 5 Volt)
   - Standby current < 2 mA
   - Operating current (no load with ring oscillator) < 1 mA
· Main oscillator: Crystal/ Ring oscillation selectable by pin option
· Input/ Output port
   - Port for input only: 1 port/4 pins
   - Input/ Output ports: 2 ports/8 pins
   - Port for output only: 1 port/4 pins
   - Can offer a direct row and column matrix of up to 72 (8 ´ 9) keys
· Interrupts
   - Internal interrupts: Timer
   - External interrupts: TG (port 0, port1), POI (Power On Initialization)
   - Priority: POI > TG > Timer
· DAC1/2 provided for stereo voice output
· Melody + Voice output for DAC1
· TG interrupt provided
   - Shared TG interrupt for Port0/Port1 input.
   - Global TG interrupt enable controlled (bit3 of the IER register)
   - Individual interrupt enable controlled (PER0 and PER1 registers)
· Built-in 8 bit programmable down count timer
   - One of two internal clock frequencies can be selected
   - Desired Timer interval = (preset value +1) ´ 1/FT ( FT: 32 Hz or 32 KHz
     dependent on the bit0 of the MODE register, at Fosc = 3 MHz)
· Powerful instruction set:
   - Arithmetic: ADD, ADDC, SUB, SUBC, INC, DEC, SETB, CLRB
   - Logic Operation: AND, OR, XOR, NOT
   - Shift & Rotate: RORC, ROLC, SHRC, SHLC
   - Date move: LD, LDR, MV
   - Branch: JP, JB0, JB1, JB2, JB3, JZ, JNZ, JC, JNC, JBZ1, JBZ2, CJNE, CJE, DJNZ, DJZ
   - Subroutine: CALL, RTN, RTI
   - Others: NOP, END, EN INT, DIS INT, PLAY CH1, STOP CH1, STOP CH2
· 8-level STACK shared by CALL, Timer, Synthesizer and TG
· Dynamic register controlled by LD instructions
   - Volume control (VOL1/VOL2 registers for DAC 1/2)
   - Melody Timbre control (Timbre0/1/2/3 registers for CH0/1/2/3)
   - Melody Speed control (Tempo register)
· 4-CH Melody with
   - Timbre-based melody synthesis
   - Note number : only limited by ROM size
   - Timbre ROM size: 16 Kbyte
- Note span: 49 notes, 4 octaves
   - 9 kinds of timbre size: 1K/2K/3K/4K/6K/8K/10K/12K/16K bytes per timbre
   - 7 kinds of loop size: one-shot /128/256/512/1K/2K/4K bytes per timbre
   - 6 kinds of note sustainments (1/4, 1/2, 1, 4/3, 2, 4 sec)
   - 4 kinds of envelope effect
   - User-defined timbre library to achieve various kind of instrument effects
   - Midi-conversion utility provided
· Multi-tasking operation via interrupt for automatic voice segment concatenation
   - Melody voice or Speech voice can be easily concatenated with symbol "+"
   - Example: PLAY CH1, H4 + Melody1 + Speech1 + Speech2 + Melody2 + T4
     The DAC1 of the W561xxx will play Melody1, Speech1, Speech2, and Melody2 sequentially.
· The length of the voice segment is only limited by the ROM size
· Speech section control
   - Fading effect, eight levels of volume control (0-7)
   - Sample rate control (4.8K/6K/8K/12K)
   - Example: PLAY CH2, H4 + speech1_SV + T4; S: define the sample rate, V: define the volume
· Provides ICE (In Circuit Emulation) system for easy debugging
   - Free Run
   - Stop Run
   - Program Reset
   - Step Into
   - Step Over
   - Go To Cursor
   - Break point
   - Register read/ modify

Description

The W588B015 is one of the derivatives of the BandDirectorTM familiy. W588B015 consists of a 4-bit mC, two voice synthesizers, one 4-CH Melody generator, and one shared ROM.

The muti-tasking operation for voice synthesis and 4-CH 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 W588B015 '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.
