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 400kHz I
2
C bus.
The CAT1025 provides a precision V
CC
sense circuit
and two open drain outputs: one (RESET) drives high
and the other (
RESET
) drives low whenever V
CC
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.
The CAT1024 also provides a precision V
CC
sense
circuit, but has only a
RESET
output and does not have
a Write Protect input.
The power supply monitor and reset circuit protect
memory and system controllers during power up/down
and against brownout conditions. Five reset threshold
Doc No. 3008, Rev. M
voltages support 5V, 3.3V and 3V systems. If power supply
voltages are out of tolerance reset signals become active,
preventing the system microcontroller, ASIC or peripherals
from operating. Reset signals become inactive typically 200
ms after the supply voltage exceeds the reset threshold
level. With both active high and low reset signals, interface
to microcontrollers and other ICs is simple. In addition, the
RESET
pin or a separate input,
MR
, can be used as an input
for push-button manual reset capability.
The CAT1024/25 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, 8-pin SOIC, 8-pin
TSSOP, 8-pin TDFN and 8-pin MSOP. The TDFN package
thickness is 0.8mm maximum. TDFN footprint is 3x3mm.
