HY62LF16406C Series
DESCRIPTION
The HY62LF16406C is a high speed, super low power and 4Mbit full CMOS SRAM organized as 256K words by 16bits. The HY62LF16406C uses high performance full CMOS process technology and is designed for high speed and low power circuit technology. It is particularly well-suited for the high density low power system application. This device has a data retention mode that guarantees data to remain valid at a minimum power supply voltage of 1.2V.
FEATURES
* Fully static operation and Tri-state output * TTL compatible inputs and outputs * Battery backup -. 1.2V(min) data retention * Standard pin configuration -. 48-ball uBGA

Notes: 1. A write occurs during the overlap of a low /WE, a low /CS1, a high CS2 and a low /UB and/or /LB . 2. tWR is measured from the earlier of /CS1, /LB, /UB, or /WE going high or CS2 going low to the end of write cycle. 3. During this period, I/O pins are in the output state so that the input signals of opposite phase to the output must not be applied. 4. If the /CS1, /LB and /UB low transition and CS2 high transition occur simultaneously with the /WE low transition or after the /WE transition, outputs remain in a high impedance state. 5. Q(data out) is the same phase with the write data of this write cycle. 6. Q(data out) is the read data of the next address. 7. Transition is measured + 200mV from steady state. This parameter is sampled and not 100% tested. 8. /CS1 in high for the standby, low for active CS2 in low for the standby, high for active. /UB and /LB in high for the standby, low for active
