RAC (ROW ADDRESS CLOCK)
RAC is an open drain output pin that normally marks the end of a row. At the 8 kHz sample frequency
the duration of this period is 256 ms. there are 1888 pages of memory in the Winbond ISD5216
device. RAC stays HIGH for 248 ms and goes LOW for the remaining 8 ms before it reaches the end
of the page.

The RAC pin remains HIGH for 500 µsec and stays LOW for 15.6 µsec under the Message Cueing
mode. See the
table on page 63 for RAC timing information at other sample rates.
Timing Parameters
When a record command is first initiated, the RAC pin remains HIGH for an extra T
period in
RACLO
order to load sample and hold circuits internal to the device. The RAC pin can be used for message
management techniques.
