DESCRIPTION

The CAT1026 and CAT1027 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 400kHz I

C bus.

The CAT1026 and CAT1027 provide a precision V

sense circuit with five reset threshold voltage options

that support 5V, 3.3V and 3V systems. The power

supply monitor and reset circuit protects memory and

systems controllers during power up/down and against

brownout conditions. If power supply voltages are out of

tolerance reset signals become active preventing the

system microcontroller, ASIC, or peripherals from

operating.

used as an input for push-button manual reset capability.

The CAT1026 and CAT1027 provide an auxiliary voltage

sensor input, V

SENSE

, which is used to monitor a second

system supply. The auxiliary high impedance comparator

drives the open drain output, V

LOW

, whenever the sense

voltage is below 1.25V threshold.

The CAT1027 is designed with a 1.6 second watchdog timer

circuit that resets a system to a known state if software or a

hardware glitch halts or “hangs” the system. The CAT1027

features a watchdog timer interrupt input, WDI.

The on-chip 2k-bit EEPROM memory features a 16-byte

page. In addition, hardware data protection is provided by a

sense circuit that prevents writes to memory whenever

falls below the reset threshold or until V
