Output Enable Input (OE#) is pin-shared with RAMCS# (RAM Enable Input) signal in order to maintain the standard 32-lead TSOP package. The SST30VR041/043 have an output enable input for precise control of the data outputs. It also has two (2) separate chip enable inputs for selection of either SRAM or ROM and for minimizing current drain during power-down mode. The SST30VR041/043 is particularly well suited for use in low voltage (2.7-3.3V) supplies such as pagers, organizers and other handheld applications. The device is fabricated using SST’s advanced CMOS low power process technology.

A write occurs during the overlap (TWP) of a low RAMCS# and low WE#. A write begins at the latest transition among RAMCS# going low and WE# going low: A write end at the earliest transition among RAMCS# going high and WE# going high, TWP is measured from the beginning of write to the end of write. 2. TCW is measured from the later of RAMCS# going low to the end of write. 3. TAS is measured from the address valid to the beginning of write. 4. TWR is measured from the end of write to the address change. 5. If RAMCS#, WE# are in the read mode during this period, the I/O pins are in the outputs Low-Z state. Inputs of opposite phase of the output must not be applied because bus contention can occur. 6. If RAMCS# goes low simultaneously with WE# going low or after WE# going low, the outputs remain high impedance state. 7. DOUT is the same phase of the latest written data in this write cycle. 8.
