Description
The R1LV0108E Series is a family of low voltage 1-Mbit static RAMs organized as 131,072-word by 8-bit, fabricated
by Renesas’s high-performance 0.15um CMOS and TFT technologies. The R1LV0108E Series has realized higher
density, higher performance and low power consumption. The R1LV0108E Series is suitable for memory applications
where a simple interfacing, battery operating and battery backup are the important design objectives. It has been
packaged in 32-pin SOP, 32-pin TSOP and 32-pin sTSOP.
Features
Single 2.7V~3.6V power supply
Small stand-by current: 0.6µA (3.0V, typical)
No clocks, No refresh
All inputs and outputs are TTL compatible.
Easy memory expansion by CS1# and CS2
Common Data I/O
Three-state outputs: OR-tie Capability
OE# prevents data contention on the I/O bus

1. tCHZ, tOHZ and tWHZ are defined as the time at which the outputs achieve the open circuit conditions and are not
referred to output voltage levels.
2. This parameter is sampled and not 100% tested.
3. At any given temperature and voltage condition, tHZ max is less than tLZ min both for a given device and from
device to device.
4. A write occurs during the overlap of a low CS1#, a high CS2, a low WE#.
A write begins at the latest transition among CS1# going low, CS2 going high and WE# going low.
A write ends at the earliest transition among CS1# going high, CS2 going low and WE# going high.
tWP is measured from the beginning of write to the end of write.
5. tCW is measured from the later of CS1# going low or CS2 going high to end of write.
6. tAS is measured the address valid to the beginning of write.
7. tWR is measured from the earliest of CS1# or WE# going high or CS2 going low to the end of write cycle.
8. Don’t apply inverted phase signal externally when DQ pin is output mode.

Note 1. Typical parameter indicates the value for the center of distribution at 3.0V (Ta= 25ºC), and not 100% tested.
2. CS2 controls address buffer, WE# buffer, CS1# buffer, OE# buffer and Din buffer. If CS2 controls data retention
mode, Vin levels (address, WE#, CS1#, OE#, DQ) can be in the high impedance state.
If CS1# controls data retention mode, CS2 must be CS2 ≥ Vcc-0.2V or 0V ≤ CS2 ≤ 0.2V. The other input levels
(address, WE# ,OE#, DQ) can be in the high impedance state.
