1Mb x16 Pseudo Static RAM Specification
GENERAL DESCRIPTION
The EM7164SU16BxP is 16,777,216 bits of Pseudo SRAM which uses DRAM type memory cells, but this device has refresh-free operation and extreme low power consumption technology. Furthermore the inter-face is compatible to a low power Asynchronous type SRAM. The E M7164SU16BxP is organized as 1,048,576 Words x 16 bit.

ABSOLUTE MAXIMUM RATINGS 1)
1. Stresses greater than those listed above “Absolute Maximum Ratings” may cause permanent damage to the device.
Functional operation should be restricted to recommended operating condition. Exposure to absolute maximum rating conditions for extended periods may affect reliability.
2. Undershoot at power-off : -1.0V in case of pulse width < 20ns
FUNCTIONAL DESCRIPTION
Note:
1. X means don’t care. (Must be low or high state)
2. This Low Power mode is supported in EM7164SU16BLP, EM7164SU16BNP & EM7164SU16BRP.
网络收集RECOMMENDED DC OPERATING CONDITIONS 1. Overshoot: V CC +1.0 V in case of pulse width < 20ns
2. Undershoot: -1.0 V in case of pulse width < 20ns
3. Overshoot and undershoot are sampled, not 100% tested. CAPACITANCE1) (f =1MHz, T A=25o C)
1. Capacitance is sampled, not 100% tested,
DC AND OPERATING CHARACTERISTICS
1. Maximum Icc specifications are tested with V CC = V CCmax.
