Description
Supply voltage: Provides the power supply for READ, PROGRAM, and ERASE operations.
The command interface is disabled when VCC VLKO. This prevents WRITE operations from ac-
cidentally damaging the data during power-up, power-down, and power surges. If the pro-
gram/erase controller is programming or erasing during this time, then the operation aborts,
and the contents being altered will be invalid.
A 0.1μF capacitor should be connected between VCC and VSS 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. (See DC Characteristics.)
I/O supply voltage: Provides the power supply to the I/O pins and enables all outputs to be
powered independently from VCC.
Ground: All VSS pins must be connected to the system ground.
Reserved for future use: RFUs should be not connected.
