GENERAL DESCRIPTION
The EM22300 series is a series of single chip ASPCM voice synthesizers fully utilizing the VLSI
technology. This full series ICs provide voice capacity ranging from 9 seconds to 60 seconds with
6K Hz sample rate. The voice content can be partitioned into sections with arbitrary length and
several sections can be combined to form complete trigger group. In addition to multiple normal
trigger inputs, ONEKEY trigger is provided to achieve random or sequential group play by triggering
pin ONE. Besides, 4 trigger modes (level mode, one-shot with retrigger mode, one-shot without
retrigger mode, and level mode with SAF1 active) of each trigger input, 3 output functions (stop pulse,
active pulse and flash) and 4 output status (active high/inactive low; active low/inactive high, active
high/inactive floating, active low/inactive floating) of control outputs are also provided to meet
diverse applications.
FEATURES
Single power supply: 2.4V~5.0V.
9 seconds to 61 seconds of voice capacity (under 6K Hz sample rate) are provided as followed:

Control output signals (SAF pins) for indicating or external device controlling are provided:
i.
Three output functions, STOP, ACT and FLASH, are selectable for each control output (SAF) by mask
option.
ii. Four output configurations, active high/active low, active low/inactive high, active high/inactivefloat-
ing, and active low/inactive floating, are selectable for each control output by mask option.
Built-in 20ms debouncing circuit for trigger inputs.
Speaker output driver and buzzer output driver (EM22309 and EM22312) are provided.
Selective speaker output current: 3 mA or 5 mA by pin option.
