DESCRIPTION
The X46402 combines several functions into one
device. The first is a dual voltage CPU supervisor plus
64Kbit serial EEPROM memory with password pro-
tected write and read operations. The size of the pass-
word protected area is selectable by 3 control bits. A
Write Protect (WP) pin in conjunction with a WPEN bit
provides hardware OTP control of the configuration of
the array. Password protected areas require 64 bit
read or write passwords prior to access.
A secondary voltage monitor circuit activates a V2FAIL
pin when the secondary supply voltage drops below a
V2trip voltage. This circuit is primarily intended to
detect the immediate loss of the battery supply.
A low V
when V
also blocks read or write operations.
CC
CC
voltage detect circuit activates a RESET pin
drops below a V
TRIP
voltage. This signal
A watchdog timer with the time period controlled by
three bits provides several possible time out periods
from 150ms to 1 minute.
