ISD-T360SA
For optimal noise immunity, the power and
ground pins should be connected to V
ground planes, respectively, on the printed circuit
board. If V
single conductors should be run directly from
each V
GND pin to a ground point. Avoid daisy-chained
connections. The VoiceDSP does not perform its
usual functions in power-down mode but it still pre-
serves stored messages, maintains the time of
day.
When you build a prototype, using wire-wrap or
other methods, solder the capacitors directly to
the power pins of the VoiceDSP processor socket,
or as close as possible, with very short leads.

Flash Support
The ISD-T360SA VoiceDSP supports Flash devices
for storing recorded data, thus, power can be dis-
connected to the ISD-T360SA without losing data.
The ISD-T360SA supports NAND Flash device inter-
faces,
TC58A040F,
KM29W16000AT. The ISD-T360SA may be con-
nected to up to four Flash devices, resulting with
maximum recording storage of 16-Mbits x 4 =
64 Mbits (up to 4 hours of recording time).
The following flash devices are supported:
