| Ordering number : EN5804A CMOS IC LC3564B, BS, BM, BT-70/10 64K (8192-word x 8-bit) SRAM with OE, CE1, and CE2 Control Pins Overview The LC3564B, LC3564BS, LC3564BM, and LC3564BT are 8192-word x 8-bit asynchronous silicon gate CMOS SRAMs. These are full CMOS type SRAMs that adopt a six-transistor memory cell and feature fast access times, low operating power dissipation, and an ultralow standby current. These SRAMs provide three control signal inputs: an OE input for high-speed memory access, and two chip enable lines, CE1 and CE2, for low power mode and device selection. These means that these SRAMs area ideal for systems that require low power and battery backup, and that they support easy memory expansion. The ultralow standby current that is a feature of these SRAMs allows them to be used with capacitor backup as well. Since these SRAMs support 3-V operation, they are also appropriate for use in portable battery operated systems. * * * * Three control inputs: OE, CE1, and CE2 Shared input and output pins, three-state outputs No clock required Packages 28-pin DIP (600 mil) plastic package: LC3564B 28-pin DIP (300 mil) plastic package: LC3564BS 28-pin SOP (450 mil) plastic package: LC3564BM 28-pin TSOP (8 x 13.4 mm) plastic package: LC3564BT Package Dimensions unit: mm 3012A-DIP28 (600 mil) [LC3564B] Features * Supply voltage range: 2.7 to 5.5 V -- In 5-V operation mode: 5.0 V 10% -- In 3-V operation mode: 3.0 V 10% * Address access time (tAA) -- In 5-V operation mode: LC3564B, BS, BM, and BT-70: 70 ns (max) LC3564B, BS, BM, and BT-10: 100 ns (max) -- In 3-V operation mode: LC3564B, BS, BM, and BT-70: 200 ns (max) LC3564B, BS, BM, and BT-10: 500 ns (max) * Ultralow standby current -- In 5-V operation mode: 1.0 A (Ta 70C), 3.0 A (Ta 85C) -- In 3-V operation mode: 0.8 A (Ta 70C), 2.5 A (Ta 85C) * Operating temperature range -- In 5-V operation mode: -40 to 85C -- In 3-V operation mode: -40 to 85C * Data retention supply voltage: 2.0 to 5.5 V * All input and output levels: -- In 5-V operation mode: TTL compatible levels -- In 3-V operation mode: VCC -0.2 V/0.2 V SANYO: DIP28 (600 mil) unit: mm 3133-DIP28 (300 mil) [LC3564BS] SANYO: DIP28 (300 mil) SANYO Electric Co.,Ltd.

Hold WE high during the read cycle. 2. Applications must not apply reverse phase signals to the DOUT pins when those pins are in the output state. 3. The time tWP is the period when CE1 and WE are low and CE2 is high, and is defined as the time from the fall of WE until either CE1 or WE rises, or CE2 falls, whichever occurs first. 4. The times tCW1 and tCW2 are periods when CE1 and WE are low and CE2 is high. They are defined as the times from the fall of CE1 or the rise of CE2 to the rise of CE1 and WE, or the fall of CE2, whichever occurs first. 5. The DOUT pins will be in the high-impedance state if either OE is high, CE1 is high, CE2 is low, or WE is low. 6. OE must be held either at VIH or VIL during the write cycle. 7. The DOUT pins have the same phase as the write cycle write data.
