NOTES:
1. Parameters are valid over specified temperature range. See ordering information table for applicable temperature range and operating
supply range.
2. Timing is illustrated and referenced to the WRN and RDN inputs. The device may also be operated with CEN as a ‘strobing’ input. CEN and
RDN (also CEN and WRN) are ANDed internally. As a consequence the signal asserted last initiates the cycle; the signal negated first
terminates the cycle. Address is latched at leading edge of a read or write cycle.
3. The RDN signal must be negated for this time to guarantee that internal registers update before the next read.
