DESCRIPTION  
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 and CAT1025 are complete memory and  
supervisorysolutionsformicrocontroller-basedsystems.  
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 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.  
The CAT1024/25 memory features a 16-byte page. In  
addition, hardware data protection is provided by a VCC  
sense circuit that prevents writes to memory whenever VCC  
falls below the reset threshold or until VCC reaches the reset  
threshold during power up.  
The CAT1024 also provides a precision VCC sense  
circuit, but has only a RESET output and does not have  
a Write Protect input.  
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.  
The power supply monitor and reset circuit protect  
memory and system controllers during power up/down  
and against brownout conditions. Five reset threshold
