28 / 45 page  28/45 ¡ Semiconductor MSM6650 Family FEDL6650-03 PIN DESCRIPTIONS 1.MSM6652/53/54/55/56-xxx, MSM6652A/53A/54A/55A/56A/58A-xxx 18-Pin plastic DIP Symbol Type Description RESET CMD ST Reset. The devices enter stanby status when a low level is input to this pin. When RESET, oscillation stops. The AOUT output goes to ground and the IC status is reinitialized. This pin has an internal pull-up resistor. I I I CH I6/SD I5/SI I I I BUSY O NAR O Busy. Outputs a "L" level during playback and a "H" level when power is turned ON. The CMD and ST inputs become effective when high. NAR indicates whether the address bus (I0 through I6) is ready to accept another address. When high, it is ready to accept. NAR goes high when power is turned ON. AOUT O Analog Speech Output. D/A converter output or LPF output is selected by entering the command. Ceramic Oscillator Output. If an external clock is used, leave this pin open. XT O Command Input and Option Control. This pin is used as command and option input when CMD is at the high level with ST low. If this pin is not used or serial input is optioned, set this pin to "H" level. This pin has an internal pull-up resistor. Start. Speech playback starts at the fall of the ST pulse. The I0 - I6 addresses are latched at the rise of the ST pulse. Input a ST pulse when NAR goes to the high level for channels 1 and 2. This pin has an internal pull-up resistor. Channel Control. Channel 1 is selected when the input is pulled high. Channel 2 is selected when the input is low. This pin has an internal pull-up resistor. This pin is command and user-defined phrase input when parallel input is optioned. This pin is serial data (command and address) input when serial input is optioned. This pin is command and user-defined phrase input when parallel input is optioned. This pin is used as serial clock input when serial input is optioned. XT I Ceramic Oscillator Input. This pin has an internal 0.5 to 5 M W feedback resistor between XT and XT. If an external clock is used, this is the clock input pin. I4 I This pin is command and user-defined phrase input when parallel input is optioned. When serial input is optioned, set this pin to "L" level. This pin has an internal pull-down resistor. I3/PORT1 I/O This pin is command and user-defined phrase input when parallel input is optioned. When serial input is optioned, this pin is a port output. The port output is controlled by entering external silence insertion code. I2/PORT0 I/O This pin is command and user-defined phrase input when parallel input is optioned. When serial input is optioned, this pin is a port output. The port output is controlled by entering external silence insertion code. I0, I1 I This pin is command and user-defined phrase input when parallel input is optioned. When serial input is optioned, set this pin to "L" level. This pin has an internal pull-down resistor. Pin 5 13 14 4 3 2 6 7 8 12 11 1 18 17 15, 16 Ground pin. GND — 9 Power supply. Insert a 0.1µF ro more bypass capacitor between this pin and GND. VDD — 10 |
