CY62167DV30 MoBL
16-Mbit (1M x 16) Static RAM
Features
* Very high speed: 55 ns * Wide voltage range: 2.20V - 3.60V * Ultra-low active power -- Typical active current: 2 mA @ f = 1 MHz -- Typical active current: 15 mA @ f = fmax * Ultra-low standby power * Easy memory expansion with CE1, CE2, and OE features * Automatic power-down when deselected * CMOS for optimum speed/power * Packages offered in a 48-ball BGA and 48-pin TSOPI reduces power consumption by 99% when addresses are not toggling. The device can also be put into standby mode when deselected (CE1 HIGH or CE2 LOW or both BHE and BLE are HIGH). The input/output pins (I/O0 through I/O15) are placed in a high-impedance state when: deselected (CE1HIGH or CE2 LOW), outputs are disabled (OE HIGH), both Byte High Enable and Byte Low Enable are disabled (BHE, BLE HIGH), or during a Write operation (CE1 LOW, CE2 HIGH and WE LOW). Writing to the device is accomplished by taking Chip Enables (CE1 LOW and CE2 HIGH) and Write Enable (WE) input 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 A19). 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 A19). Reading from the device is accomplished by taking 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 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.

Notes: 2. NC pins are not connected on the die. 3. DNU pins have to be left floating. 4. The BYTE pin in the 48-TSOPI package has to be tied HIGH 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 LOW. For 2M x 8 Functionality, please refer to the CY62168DV30 datasheet. In the 2M x 8 configuration, Pin 45 is A20. 5. Ball H6 for the FBGA package can be used to upgrade to a 32M density.

Notes: 14. Test conditions for all parameters other than three-state parameters assume signal transition time of 1 ns/V, 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 the "AC Test Loads and Waveforms" section. 15. 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. 16. tHZOE, tHZCE, tHZBE, and tHZWE transitions are measured when the outputs enter a high impedance state. 17. The internal Write time of the memory is defined by the overlap of WE, CE1 = VIL, BHE and/or BLE = 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 set-up and hold timing should be referenced to the edge of the signal that terminates the Write.
