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 400 kHz I
2
C bus.
The CAT1026 and CAT1027 provide a precision V
CC
sense circuit
with five reset threshold voltage options that support 5 V, 3.3 V and

3 V 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.
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 200 ms
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.
CASE 846AD
CASE 511AL
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,

LOW
, whenever the sense voltage is below 1.25 V threshold.
For Ordering Information details, see page 13.
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
CC
sense circuit that prevents writes to memory whenever V
CC
falls below the reset threshold or until V
CC
reaches the reset
threshold during power up.
Available packages include an 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 0.8 mm maximum. TDFN footprint is 3 x 3 mm.
