FEATURES
z Stand CMOS process.
z Embedded 1M bit EPROM.
z 40 Sec Voice Length at 6 KHz sampling and 4‐bit ADPCM compression.
z Built‐in oscillator to control sampling frequency without an external resistor .
z Maximum 64 voice groups.
z One groups contain several steps(voice section) ;Maximum 700 steps for all the groups.
z User selectable 8bit / 5bit / 4bit data compression.
z 2 input pin(TG1&TG2) and 6 user selectable input or output pin (TG5 & TG6 & TG7 & TG8 & TG11 & TG12).
z Two triggering modes are available by whole chip option during voice compilation
‐ Key Trigger Mode – Up 64 Voice Groups are trigger by TG1 & TG2 & TG5~TG8 & TG11 & TG12
‐ Serial Trigger Mode‐Combinations of TG1 and TG5 to trigger maximum 32 Voice Groups.
‐ CPU Serial Trigger Mode – user commands are clocked serially into the chip to control the playback of chip.
z Voice Group Trigger Options: Edge/LEVEL; Hold/Un‐hold; Retrigger/Non‐retrigger.
z User selectable 50us (@8KHz sampling rate) or 10ms (@8KHz sampling rate) Debounce Time in all of three
trigger Modes.
z Two user programmable outputs for FLASH(0.75Hz/1.5Hz/3Hz/6Hz) or BUSY(High/Low).
z Support Power‐on play.
z 2.6 ~ 5.0V;Wide range single power supply and <1uA low stand‐by current.
z PWM pwm1 and pwm2 drive speaker directly.
z D/A PWM2 to drive speaker through an external BJT or OP.
z Development System support voice compilation and options selection.
DESCRIPTION
AK040FDIP16
high performance Voice OTP is fabricated with Standard C MOS process with embedded 1M bit EPROM. It
can srore up 40sec voice message with 4bit data compression at 6KHz sampling rate.5bit and 8bit data
compression are also available as user selectable option.Three trigger modes,simple Key trigger mode and Serial
trigger mode and CPU Command mode facilitate different user interface。Internal oscillator to control smpling
during the voice playback,8bit current mode D/A output and PWM direct speaker driving output minimize the
number of external components. PC controlled programmer and developing software are available.

Input Options:
User selectable options how to trigger each individual group for each input pin in Key Trigger Mode.They are:
z Edge / Level trigger
z Unholdable / Holdable trigger
z Re‐triggerable / Non‐retriggerable
