V62C1802048L(L)
Ultra Low Power
256K x 8 CMOS SRAM
Features
• Low-power consumption
Functional Description
The V62C1802048L is a low power CMOS Static RAM orga-
nized as 262,144 words by 8 bits. Easy memory expansion is p-
rovided by an active LOW CE1 , an active HIGH CE2, an act-
- Active: 25mA at 70ns
- Stand-by: 10 mA (CMOS input/output)
2 mA CMOS input/output, L version
, and Tri-state I/O’s. This device has an auto-
ive LOW OE
matic power-down mode feature when deselected.
• Single + 1.8 to 2.2V Power Supply
• Equal access and cycle time
• 70/85/100/150 ns access time
Writing to the device is accomplished by taking Chip E-
nable 1 (CE1
) LOW, and Chip En-
) with Write Enable (WE
able 2 (CE2) HIGH. Reading from the device is performed
by taking Chip Enable 1 (CE1
) with Output Enable
(OE ) LOW while Write Enable (WE ) and Chip Enable 2
(CE2) is HIGH. The I/O pins are placed in a high-imped-
ance state when the device is deselected: the outputs are
disabled during a write cycle.
• Easy memory expansion with CE1, CE2
and OE inputs
• 1.0V data retention mode
The V62C1802048LL comes with a 1V data retention feature
and Lower Standby Power. The V62C1802048L is available in
a 32-pin 8 x 13.4 & 8 x 20 mm TSOP1 / STSOP packages.
• TTL compatible, Tri-state input/output
• Automatic power-down when deselected
• Package available: 32-TSOP1 / STSOP

Notes
1. L-version includes this feature.
2. This Parameter is samples and not 100% tested.
3. For test conditions, see AC Test Condition, Figure A.
4. This parameter is tested with CL = 5pF as shown in Figure B. Transition is measured + 500mV from steady-state voltage.
5. This parameter is guaranteed, but is not tested.
6. WE is HIGH for read cycle.
7. CE1 and OE are LOW and CE2 is HIGH for read cycle.
8. Address valid prior to or coincident with CE1 transition LOW or CE2 transition HIGH.
9. All read cycle timings are referenced from the last valid address to the first transtion address.
10. CE1 or WE must be HIGH or CE2 must be LOW during address transition.
11. All write cycle timings are referenced from the last valid address to the first transition address.
