POWER-ON DATA PROTECTION
In order to prevent data corruption and inadvertent
write operations during power-up and power-down,
a Power On Reset (POR) circuit resets all internal
programming circuitry and sets the device in the
Write Disable mode.
– At Power-up and Power-down, the device
must NOT be selected (that is, the S input
must be driven low) until the supply voltage
reaches the operating value Vcc specified in
the AC and DC tables.
– When VCC reaches its functional value, the de-
vice is properly reset (in the Write Disable
mode) and is ready to decode and execute an
incoming instruction.
For the M93Sx6 specified at 5V, the POR threshold
voltage is around 3V.
For all the other M93Sx6 specified at low VCC (with
-W and -R VCC range options), the POR threshold
voltage is around 1.5V.
