Description

Inputs/Outputs. The I/O pins are used for command input, address input, data input, and data output. The

I/O pins float to High-Z when the device is deselected or the outputs are disabled.

Command Latch Enable. This input activates the latching of the I/O inputs inside the Command Register on the

rising edge of Write Enable (WE#).

Address Latch Enable. This input activates the latching of the I/O inputs inside the Address Register on the rising

edge of Write Enable (WE#).

Chip Enable. This input controls the selection of the device. When the device is not busy CE# low selects the

memory.

Write Enable. This input latches Command, Address and Data. The I/O inputs are latched on the rising edge of

WE#.

Read Enable. The RE# input is the serial data-out control, and when active drives the data onto the I/O bus. Data is

valid tREA after the falling edge of RE# which also increments the internal column address counter by one.

Write Protect. The WP# pin, when low, provides hardware protection against undesired data modification

(program / erase).

Ready Busy. The Ready/Busy output is an Open Drain pin that signals the state of the memory.

Supply Voltage. The VCC supplies the power for all the operations (Read, Program, Erase). An internal lock circuit

prevents the insertion of Commands when VCC is less than VLKO.

Ground.

Not Connected.

Notes:

1. A 0.1 µF capacitor should be connected between the VCC Supply Voltage pin and the VSS Ground pin to decouple the current surges from

the power supply. The PCB track widths must be sufficient to carry the currents required during program and erase operations.

2. An internal voltage detector disables all functions whenever VCC is below 1.8V to protect the device from any involuntary program/erase

during power transitions.
