W562XXX Datasheet, PDF (3/8 Pages) Winbond – DUAL-TONE MELODY WITH VOICE SYNTHESIZER (BandDirector Series)

W562XXX
− ICE & ROM chips use different Rosc. Rosc for mass production should check “W562 Freq vs
R.pdf” file for more details.
• Wide operating voltage range: 2.4 to 5.5 volts
• Low power consumption (VDD = 5 Volt)
− Standby current < 1 µA
− Operating current < 1 mA
• Main oscillator: 3 MHz, Ring oscillation
• 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
• Melody + Voice outputs for DAC
• TG interrupt provided
− Share 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)
• A total of around 64,000 instructions can be used in the program
• 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, PLAY CH2, STOP CH1, STOP CH2
