CY62167EV30 MoBL(R) 16-Mbit (1M x 16 / 2M x 8) Static RAM Features * * * * TSOP I package configurable as 1M x 16 or as 2M x 8 SRAM Very high speed: 45 ns Wide voltage range: 2.20V-3.60V Ultra low standby power -- Typical standby current: 1.5 A -- Maximum standby current: 12 A * Ultra low active power * * * * -- Typical active current: 2.2 mA @ f = 1 MHz Easy memory expansion with CE1, CE2, and OE features Automatic power down when deselected CMOS for optimum speed/power Offered in Pb-free 48-ball BGA and 48-pin TSOP I packages Functional Description[1] The CY62167EV30 is a high performance CMOS static RAM organized as 1M words by 16 bits / 2M words by 8 bits. This device features advanced circuit design to provide an ultra low active current. This is ideal for providing More Battery LifeTM (MoBL(R)) in portable applications such as cellular telephones. The device also has an automatic power down feature that significantly reduces power consumption by 99% when addresses are not toggling. Place the device into standby mode when deselected (CE1 HIGH or CE2 LOW or both BHE and BLE are HIGH). The input and output pins (IO0 through IO15) are placed in a high-impedance state when: the device is deselected (CE1 HIGH or CE2 LOW), outputs are disabled (OE HIGH), both Byte High Enable and Byte Low Enable are disabled (BHE, BLE HIGH), or a write operation is in progress (CE1 LOW, CE2 HIGH and WE LOW). To write to the device, take Chip Enables (CE1 LOW and CE2 HIGH) and Write Enable (WE) input LOW. If Byte Low Enable (BLE) is LOW, then data from IO pins (IO0 through IO7) is written into the location specified on the address pins (A0 through A19). If Byte High Enable (BHE) is LOW, then data from the IO pins (IO8 through IO15) is written into the location specified on the address pins (A0 through A19). To read from the device, take Chip Enables (CE1 LOW and CE2 HIGH) 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 IO0 to IO7. If Byte High Enable (BHE) is LOW, then data from memory will appear on IO8 to IO15. See the "Truth Table" on page 10 for a complete description of read and write modes.

NC pins are not connected on the die. 3. The BYTE pin in the 48-TSOPI package has to be tied to VCC to use the device as a 1M X 16 SRAM. The 48-TSOPI package can also be used as a 2M X 8 SRAM by tying the BYTE signal to VSS. In the 2M x 8 configuration, Pin 45 is A20, while BHE, BLE and IO8 to IO14 pins are not used. 4. Ball H6 for the FBGA package can be used to upgrade to a 32M density. 5. Typical values are included for reference only and are not guaranteed or tested. Typical values are measured at VCC = VCC(typ), TA = 25C.

VIL(min) = -2.0V for pulse durations less than 20 ns. 7. VIH(max) = VCC + 0.75V for pulse durations less than 20 ns. 8. Full Device AC operation assumes a 100 s ramp time from 0 to VCC (min) and 200 s wait time after VCC stabilization. 9. Under DC conditions the device meets a VIL of 0.8V. However, in dynamic conditions Input LOW Voltage applied to the device must not be higher than 0.7V. This is applicable to TSOP I package only. 10. Only chip enables (CE1 and CE2), byte enables (BHE and BLE) and BYTE need to be tied to CMOS levels to meet the ISB2 / ICCDR spec. Other inputs can be left floating. 11. Tested initially and after any design or process changes that may affect these parameters.

Test conditions for all parameters other than tri-state parameters assume signal transition time of 1 V/ns, timing reference levels of VCC(typ)/2, input pulse levels of 0 to VCC(typ), and output loading of the specified IOL/IOH as shown in "AC Test Loads and Waveforms" on page 4. 15. AC timing parameters are subject to byte enable signals (BHE or BLE) not switching when chip is disabled. See application note AN13842 for further clarification. 16. 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. 17. tHZOE, tHZCE, tHZBE, and tHZWE transitions are measured when the outputs enter a high impedance state. 18. The internal write time of the memory is defined by the overlap of WE, CE1 = VIL, BHE or BLE or both = VIL, and CE2 = VIH. All signals must be ACTIVE to initiate a write and any of these signals can terminate a write by going INACTIVE. The data input setup and hold timing should be referenced to the edge of the signal that terminates the write.
