Datasheet Summary
CAT1024, CAT1025
Supervisory Circuits with EEPROM Serial 2k-bit I2C and Manual Reset
Description The CAT1024 and CAT1025 are plete 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.
