Function
Chip Select Input.
at a high impedance state. Unless a nonvolatile write cycle is underway, the
device will be in the standby power mode. CS LOW enables the device, plac-
ing it in the active power mode. Prior to the start of any operation after power
up, a HIGH to LOW transition on CS is required.
Watchdog Input.
A HIGH to LOW transition on the WDI pin restarts the watch-
dog timer. The absence of a HIGH to LOW transition within the watchdog time
out period results in RESET/RESET going active.
Serial Output.
SO is a push/pull serial data output pin. A read cycle shifts data
out on this pin. The falling edge of the serial clock (SCK) clocks the data out.
Serial Input.
SI is a serial data input pin. Input all opcodes, byte addresses, and
memory data on this pin. The rising edge of the serial clock (SCK) latches the in-
put data. Send all opcodes (Table 1), addresses and data MSB first.
Serial Clock.
The serial clock controls the serial bus timing for data input and
output. The rising edge of SCK latches in the opcode, address, or data bits
present on the SI pin. The falling edge of SCK changes the data output on the
SO pin.
Write Protect.
The WP pin works in conjunction with a nonvolatile WPEN bit to
“l(fā)ock” the setting of the watchdog timer control and the memory write protect bits.

Reset Output
.
RESET/RESET is an active LOW/HIGH, open drain output
which goes active whenever V
CC
falls below the minimum V
It will remain active until V
CC
rises above the minimum V
200ms. RESET/RESET goes active if the watchdog timer is enabled and CS
remains either HIGH or LOW longer than the selectable watchdog time out
period. A falling edge of CS will reset the watchdog timer. RESET/RESET
goes active on power up at about 1V and remains active for 200ms after the
power supply stabilizes.
No internal connections
