DESCRIPTION
The HY62LF16804A is a high speed, super low
power and 8Mbit full CMOS SRAM organized as
524,288 words by 16bits. The HY62LF16804A
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(LL/SL-part)
- 1.2V(min) data retention
Standard pin configuration
- 48-uBGA

Notes:
1. A write occurs during the overlap of a low / WE, a low /CS1 and low /UB and /or /LB
2. tWR is measured from the earlier of /CS, /LB, /UB, or /WE going high 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 /CS, /LB and /UB low 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. /CS in high for the standby, low for active
/UB and /LB in high for the standby, low for active
