AS1C512K16P-70BIN
The
AS1C512K16P-70BIN
is 8,388,608 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 interface is compatible to a low power Asynchronous type SRAM. The
AS1C512K16P-70BIN
is
organized as 524,288 Words x 16 bit.

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
