the device into standby mode reduces power consumption by
more than 99% when deselected (CE HIGH). The input and
output pins (IO0 through IO15) are placed in a high impedance
state when:

packages
Write to the device by taking Chip Enable (CE) and Write Enable
(WE) inputs 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 A16). If Byte High
Enable (BHE) is LOW, then data from IO pins (IO8 through IO15)
is written into the location specified on the address pins (A0
through A16).
Read from the device 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 appears on IO0 to IO7. If
Byte High Enable (BHE) is LOW, then data from memory
appears on IO8 to IO15. See the “Truth Table” on page 9 for a
complete description of read and write modes.
Functional Description

Notes
11. Test conditions for all parameters, other than tri-state parameters, assume signal transition time of 3 ns (1V/ns) 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 as shown in the “AC Test Loads and Waveforms” on page 4.
12. AC timing parameters are subject to byte enable signals (BHE or BLE) not switching when chip is disabled. Please see application note AN13842 for further clarification.
13. 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.
14. tHZOE, tHZCE, tHZBE, and tHZWE transitions are measured when the outputs enter a high impedance state.
15. The internal write time of the memory is defined by the overlap of WE, CE = VIL, BHE and/or BLE = VIL. All signals are ACTIVE to initiate a write and any of these
signals can terminate a write by going INACTIVE. The data input setup and hold timing are referenced to the edge of the signal that terminates the write.
