One Channel Direct Drive Speech Controller
5.6. I/O Ports
P2 and P3 are two 4-bit I/O ports. Any bit of P2 and P3 can be programmed as
either input or output port individually. Any valid data transition (H
L or L
H) of
P2 and P3 can reactivate the chip when the chip is in power-down stage.

Note: Weak N-MOS can serve as pull-low resistor.
5.7. DAC & PWM
SNC510 is an advanced chip to be designed having two optimal methods to play
out the voices. One is DAC and the other is PWM. Upon user’s applications, user
can select either DAC or PWM in his design. Please be aware that only one
method can be activated at a time.
DAC
: A 7-bit current type digital-to-analog converter is built-in SNC510. The
relationship between input digital data and output analog current signal is listed
in the following table. Also, the recommended application circuit is illustrated as
follows.
