BS62LV1025
DESCRIPTION
FEATURES
The BS62LV1025 is a high performance, very low power CMOS
Static Random Access Memory organized as 131,072 words by 8 bits
and operates from a wide range of 4.5V to 5.5V supply voltage.
Advanced CMOS technology and circuit techniques provide both high
speed and low power features with a typical CMOS standby current of
0.4uA and maximum access time of 55ns in 5V operation.
• Vcc operation voltage : 4.5V ~ 5.5V
• Very low power consumption :
Vcc = 5.0V C-grade : 35mA (Max.) operating current
I- grade : 40mA (Max.) operating current
0.4uA (Typ.) CMOS standby current
• High speed access time :
Easy memory expansion is provided by an active LOW chip
enable (CE1), an active HIGH chip enable (CE2), and active LOW
output enable (OE) and three-state output drivers.

55ns (Max.) at Vcc = 5.0V
70ns (Max.) at Vcc = 5.0V
• Automatic power down when chip is deselected
• Three state outputs and TTL compatible
• Fully static operation
The BS62LV1025 has an automatic power down feature, reducing the
power consumption significantly when chip is deselected.
The BS62LV1025 is available in DICE form, JEDEC standard 32 pin
450mil Plastic SOP, 300mil Plastic SOJ, 600mil Plastic DIP,
8mmx13.4mm STSOP and 8mmx20mm TSOP.
• Data retention supply voltage as low as 1.5V
• Easy expansion with CE2, CE1, and OE options

PIN DESCRIPTIONS

Function
A0-A16 Address Input
These 17 address inputs select one of the 131,072 x 8-bit words in the RAM
CE1 Chip Enable 1 Input
CE2 Chip Enable 2 Input
CE1 is active LOW and CE2 is active HIGH. Both chip enables must be active when
data read from or write to the device. If either chip enable is not active, the device is
deselected and is in a standby power mode. The DQ pins will be in the high
impedance state when the device is deselected.
WE Write Enable Input
OE Output Enable Input
The write enable input is active LOW and controls read and write operations. With the
chip selected, when WE is HIGH and OE is LOW, output data will be present on the
DQ pins; when WE is LOW, the data present on the DQ pins will be written into the
selected memory location.
The output enable input is active LOW. If the output enable is active while the chip is
selected and the write enable is inactive, data will be present on the DQ pins and they
will be enabled. The DQ pins will be in the high impedance state when OE is inactive.
These 8 bi-directional ports are used to read data from or write data into the RAM.

NOTES:
1. WE must be high during address transitions.
2. The internal write time of the memory is defined by the overlap of CE1 and CE2 active and WE low.
All signals must be active to initiate a write and any one signal can terminate a write by going
inactive. The data input setup and hold timing should be referenced to the second transition edge
of the signal that terminates the write.
3. TWR is measured from the earlier of CE1 or WE going high or CE2 going low at the end of write
cycle.
4. During this period, DQ pins are in the output state so that the input signals of opposite phase to the
outputs must not be applied.
5. If the CE1 low transition or the CE2 high transition occurs simultaneously with the WE low
transitions or after the WE transition, output remain in a high impedance state.
6. OE is continuously low (OE = VIL ).
7. DOUT is the same phase of write data of this write cycle.
8. DOUT is the read data of next address.
9. If CE1 is low and CE2 is high during this period, DQ pins are in the output state. Then the data input
signals of opposite phase to the outputs must not be applied to them.
10. Transition is measured 500mV from steady state with CL = 5pF as shown in Figure 1B. The
parameter is guaranteed but not 100% tested.
11. TCW is measured from the later of CE1 going low or CE2 going high to the end of write.
