CY62147CV18 MoBL2™ 256K x 16 Static RAM Features • High Speed — 55 ns and 70 ns availability • Low voltage range: — CY62147CV18: 1.65V−1.95V • Pin Compatible w/ CY62147V18/BV18 • Ultra-low active power — Typical Active Current: 0.5 mA @ f = 1 MHz • • • • — Typical Active Current: 2 mA @ f = fmax (70 ns speed) Low standby power Easy memory expansion with CE and OE features Automatic power-down when deselected CMOS for optimum speed/power power consumption by 99% when addresses are not toggling. The device can also be put into standby mode when deselected (CE HIGH or both BLE and BHE are HIGH). The input/output pins (I/O0 through I/O15) are placed in a high-impedance state when: deselected (CE HIGH), outputs are disabled (OE HIGH), both Byte High Enable and Byte Low Enable are disabled (BHE, BLE HIGH), or during a write operation (CE LOW and WE LOW). Writing to the device is accomplished by taking Chip Enable (CE) and Write Enable (WE) inputs LOW. If Byte Low Enable (BLE) is LOW, then data from I/O pins (I/O0 through I/O7), is written into the location specified on the address pins (A0 through A17). If Byte High Enable (BHE) is LOW, then data from I/O pins (I/O8 through I/O15) is written into the location specified on the address pins (A0 through A17). Reading from the device is accomplished by taking Chip Enable (CE) and Output Enable (OE) LOW while forcing the Write Enable (WE) HIGH. If Byte Low Enable (BLE) is LOW, then data from the memory location specified by the address pins will appear on I/O0 to I/O7. If Byte High Enable (BHE) is LOW, then data from memory will appear on I/O8 to I/O15. See the Truth Table at the back of this data sheet for a complete description of read and write modes. The CY62147CV18 is available in a 48-ball FBGA package. Functional Description The CY62147CV18 is a high-performance CMOS static RAM organized as 256K words by 16 bits. This device features advanced circuit design to provide ultra-low active current. This is ideal for providing More Battery Life™ (MoBL™) in portable applications such as cellular telephones. The device also has an automatic power-down feature that significantly reduces Logic Block Diagram DATA IN DRIVERS A10 A9 A8 A7 A6 A5 A4 A3 A2 A1 A0 ROW DECODER 256K x 16 RAM Array 2048 X 2048 SENSE AMPS I/O0–I/O7 I/O8–I/O15 COLUMN DECODER BHE WE CE OE BLE CE BHE BLE A11 A12 A13 A14 A15 A16 Pow er Down Circuit MoBL, MoBL2, and More Battery Life are trademarks of Cypress Semiconductor Corporation.

Test conditions assume signal transition time of 3ns or less, timing reference levels of VCC(typ)/2, input pulse levels of 0 to VCC(typ), and output loading of the specified IOL/IOH and 30-pF load capacitance. 9. At any given temperature and voltage condition, tHZCE is less than tLZCE, tHZBE is less than tLZBE, tHZOE is less than tLZOE, and tHZWE is less than tLZWE for any given device. 10. tHZOE, tHZCE, tHZBE, and tHZWE transitions are measured when the outputs enter a high impedance state. 11. The internal write time of the memory is defined by the overlap of WE, CE = VIL, BHE and/or BLE =VIL. All signals must be ACTIVE to initiate a write and any of these signals can terminate a write by going INACTIVE. The data input set-up and hold timing should be referenced to the edge of the signal that terminates the write Document #: 38-05011 Rev. *B Page 5 of 12 CY62147CV18 MoBL2™ Switching Waveforms [12, 13] Read Cycle No. 1 (Address Transition Controlled) tRC ADDRESS tOHA DATA OUT PREVIOUS DATA VALID tAA DATA VALID Read Cycle No. 2 (OE Controlled) [13, 14] ADDRESS CE tACE OE tRC tPD tHZCE BHE/BLE tDOE tHZOE tLZOE tDBE tLZBE tHZBE HIGH IMPEDANCE DATA VALID DATA OUT HIGH IMPEDANCE tLZCE VCC SUPPLY CURRENT tPU 50% 50% ICC ISB Notes: 12.
