CE1, CE2 Chip Enable Inputs CE1 is active LOW and CE2 is active HIGH. Both chip enables must be active to read from or write to the device. If either chip enable is not active, the device is deselected and is in a standby power mode. The I/O pins will be in the high-impedance state when deselected. Output Enable Input OE The Output Enable input is active LOW. When OE is LOW with CE1 LOW, CE2 HIGH, and WE HIGH, data of the selected memory location will be available on the I/O pins. When OE is HIGH, the I/O pins will be in the high impedance state. V62C51864 WE Write Enable Input An active LOW input, WE input controls read and write operations. When CE1 and WE inputs are both LOW with CE2 HIGH, the data present on the I/O pins will be written into the selected memory location. I/O0 –I/O7 Data Input/Output Ports These 8 bidirectional ports are used to read data from and write data into the RAM.

The internal write time of the memory is defined by the overlap of 1 and CE active and WElow. Both signals must be active to CE 2 initiate and any one signal can terminate a write by going inactive. The data input setup and hold timing should be referenced to the second transition edge of the signal that terminates the write. 2. tWR is measured from the earlier of CE or WE going HIGH, or CE going LOW at the end of the write cycle. 1 2 3. During this period, I/O pins are in the output state so that the input signals of opposite phase to the outputs must not be applied. 4. OE = VIL or VIH. However it is recommended to keep OEt VIH during write cycle to avoid bus contention. a 5. If CE is LOW and CE is HIGH during this period, I/O pins are in the output state. Then the data input signals of opposite phase 1 2 to the outputs must not be applied to them. 6. tCW is measured from CE going LOW or CE going HIGH to the end of write. 1 2 V62C51864 Rev. 2.1 June 1998 8 MOSEL VITELIC Package Diagrams 28-pin 600 mil Plastic DIP V62C51864 15¡ MAX INDEX 0.543 ±0.010 [13.79 ±0.254] 0.600 [15.24] TYP +0.008 1.407 –0.012 +0.203 35.56 –0.305 0.010 ±0.002 [0.254 ± 0.51] +0.020 0.039 –0.022 +0.508 0.991 –0.559 0.195 [4.95] MAX 0.118 [3.00] MIN 0.062 [1.57] MAX Units in inches [mm] 0.100 [2.54] TYP. 0.020 [0.508] MIN 0.060 +0.020 –0.022 0.152 +0.508 –0.559 0.018 ±0.003 [0.457 ±0.076] 28-pin 330 mil SOP Units in inches [mm] 0 MIN (STAND OFF) 0.339 ± 0.008 [8.61 ± 0.203] 0.465 ± 0.012 [11.81 ± 0.305] 0.402 ±0.012 [10.21 ± 0.203] 0.031 ± 0.008 [0.787 ± 0.203] INDEX 0.713 [18.11] TYP 0.006 ± 0.002 [0.152 ± 0.051] 0.112 [0.285] MAX "A" 0.098 ± 0.005 [2.49 ± 0.127] 0.018 ± 0.004 [0.457 ± 0.102] 0.008 [0.203] View "A" 0.050 [1.27] TYP 0.024 [0.610] 0.008 [0.203] MAX 0.027 [0.686] MAX V62C51864 Rev. 2.1 June 1998 9 MOSEL VITELIC U.S.A. 3910 NORTH FIRST STREET SAN JOSE, CA 95134 PHONE: 408-433-6000 FAX: 408-433-0185 WORLDWIDE OFFICES TAIWAN 7F, NO. 102 MIN-CHUAN E.
