2.9.1 Block Diagram

2.9.2 Pin Connections and short description

Pin No. Pin Name I/O Pin Function

1CS#

(Chip Select)

I Places device in active power mode when driven low.

Deselects device and places SO at high impedance when high.

After power-up, device requires a falling edge on CS# before any command is written.

Device is in standby mode when a program, erase, or Write Status Register operation is not in progress.

2SO

(Signal data Output)

O Transfers data serially out of the device on the falling edge of SCK.

3W#

(Write Protect)

I Protects the memory area specified by Status Register bits BP2:BP0.

When driven low, prevents any program or erase command from altering the data in the protected mem-

ory area.

4 GND — Ground

5SI

(Serial Data Input)

I Transfers data serially into the device. Device latches commands, addresses, and

program data on SI on the rising edge of SCK.

6SCK

(Serial Clock)

I Provides serial interface timing.

Latches commands, addresses, and data on SI on rising edge of SCK.

Triggers output on SO after the falling edge of SCK.

7 HOLD# I Pauses any serial communication with the device without deselecting it. When driven low, SO is at high

impedance, and all input at SI and SCK are ignored. Requires that CS# also be driven low.

8 VCC — Supply Voltage
