CAT1024, CAT1025
Supervisory Circuits with EEPROM Serial 2k-bit I2C and Manual Reset
Description The CAT1024 and CAT1025 are complete memory and supervisory
solutions for microcontroller−based systems.
A 2k−bit serial EEPROM memory and a system power supervisor with brown−out protection are integrated together in low power
CMOS technology.
Memory interface is via a 400 kHz I2C bus.
The CAT1025 provides a precision VCC sense circuit and two open drain outputs: one (RESET) drives high and the other (RESET) drives low whenever VCC falls below the reset threshold
voltage.
The CAT1025 also has a Write Protect input (WP).
Write operations are disabled if WP is connected to a logic high.
