DESCRIPTION
The Intersil X45620 combines power-on reset control,
battery switch circuit, watchdog timer, supply voltage
supervision, secondary voltage supervision, block lock
protect and serial EEPROM in one package. This
combination lowers system cost, reduces board space
requirements, and increases reliability.
Applying power to the device activates the power-on
reset circuit which holds RESET active for a period of
time. This allows the power supply and oscillator to
stabilize before the processor can execute code.
A system battery switch circuit compares VCC (V1MON)
with VBATT input and connects VOUT to whichever is
higher. This provides voltage to external SRAM or other
circuits in the event of main power failure. The X45620
can drive 50mA from VCC and 250µA from VBATT. The
device switches to VBATT when VCC drops below the
low VCC voltage threshold and VBATT > VCC.

Note 4
Notes: (8) tWC is the minimum cycle time to be allowed from the system perspective unless polling techniques are used. It is the maximum time
the device requires to automatically complete the internal write operation.
The write cycle time is the time from a valid stop condition of a write sequence to the end of the internal erase/write
cycle. During the write cycle, the X45620 bus interface circuits are disabled, SDA is allowed to remain HIGH, and the
device does not respond to its slave address.
