For Ordering Information details, see page 19.

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 V

sense circuit that prevents writes to memory

whenever V

falls below the reset threshold or until V

reaches the reset threshold during power up.

Available packages include 8-pin DIP and surface

mount, 8-pin SO, 8-pin TSSOP, 8-pin TDFN and 8-pin

MSOP packages. The TDFN package thickness is

0.8mm maximum. TDFN footprint is 3 x 3mm.

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.

The CAT1026 features two open drain reset outputs:

¯¯¯¯¯¯

one (RESET) drives high and the other (RESET)

drives low whenever V

falls below the threshold.

Reset outputs become inactive typically 200ms after

the supply voltage exceeds the reset threshold value.

With both active high and low reset signals, interface

to microcontrollers and other ICs is simple. CAT1027

¯¯¯¯¯¯

has only a RESET output. In addition, the RESET pin

can be 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 impe-

dance comparator drives the open drain output, V

LOW

whenever the sense voltage is below 1.25V threshold.

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 techno–

logy. 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
