Preliminary
GENERAL DESCRIPTION
EM22000 series is a series of single chip ASPCM voice synthesizers fully utilizing the VLSI technology.
It provide 3 seconds to 6 seconds of voice capacity with 6.4K Hz sample rate. The voice content can be partitioned
into sections with arbitrary length and several sections can be combined to form a complete trigger group. In
addition to multiple normal trigger inputs, Trigger 2 provides ONEKEY function to achieve random or sequential
group playing. 4 trigger modes (level mode, one-shot with re-trigger mode, one-shot without re-trigger mode and
level hold mode with SAF3 active) of each trigger input, 3 output functions (stop pulse, active pulse and flash)
and 2 output status (active high/inactive low; active low/inactive high) of control outputs are also provided to
meet diverse applications.
FEATURES
Single power supply: 2.2V~5.2V.
3 seconds to 6 seconds voice capacity under 6.4K Hz sample rate.
Device
22003
22006
Capacity
3 sec.
6 sec.
6.4K Hz, 8K Hz sample rates of each voice section is selective by mask option.
Normal triggers with optional ONEKEY function (random/sequential) are provided.
Four trigger configuration can be selected by mask option normal trigger inputs or keyboard scan inputs.
i.
3 trigger inputs by pure trigger
ii. 6 trigger inputs by keyboard scan
iii. 8 trigger inputs by keyboard scan
iv. 3 trigger inputs with ONEKEY function by pure trigger
One of four trigger modes for each trigger input can be selected by option :
i.
Level mode
ii. One-shot with re-trigger mode
iii. One-shot without re-trigger mode
iv. Level mode with SAF3 active
Three control output signal (SAF pins) for indicating or external device controlling are provide :
i.
Three output functions, STOP, ACT and FLASH, are selective for each control output (SAF) by mask
option.
ii. Two output configurations, active high/inactive low, active low/inactive high, are selective for each
control output by mask option.
Built-in de-bounce circuit for about 20 ms.
Flash with volume function is provided.
Built in PWM driver to drive speaker directly.
