2 / 15 page X84256 Preliminary 2 PIN CONFIGURATIONS Drawings are to the same scale, actual package sizes are shown in inches: PIN NAMES PIN DESCRIPTIONS Chip Enable (CE) The Chip Enable input must be LOW to enable all read/ write operations. When CE is HIGH, the chip is dese- lected, the I/O pin is in the high impedance state, and unless a nonvolatile write operation is underway, the device is in the standby power mode. Output Enable (OE) The Output Enable input must be LOW to enable the out- put buffer and to read data from the device on the I/O line. Write Enable (WE) The Write Enable input must be LOW to write either data or command sequences to the device. Data In/Data Out (I/O) Data and command sequences are serially written to or serially read from the device through the I/O pin. Write Protect (WP) When the Write Protect input is LOW, nonvolatile writes to the device are disabled. When WP is HIGH, all functions, including nonvolatile writes, operate normally. If a nonvol- atile write cycle is in progress, WP going LOW will have no effect on the cycle already underway, but will inhibit any additional nonvolatile write cycles. DEVICE OPERATION The X84256 serial EEPROM is designed to interface directly with most microprocessor buses. Standard CE, OE, and WE signals control the read and write opera- tions, and a single l/O line is used to send and receive data and commands serially.
