X5328/X5329  
CPU Supervisor with 32Kbit SPI EEPROM  
FEATURES  
DESCRIPTION  
• Low V detection and reset assertion  
These devices combine three popular functions, Power-  
on Reset Control, Supply Voltage Supervision, and  
Block Lock Protect Serial EEPROM Memory in one  
package. This combination lowers system cost, reduces  
board space requirements, and increases reliability.  
CC  
—Five standard reset threshold voltages  
—Re-program low V reset threshold voltage  
CC  
using special programming sequence  
—Reset signal valid to V = 1V  
CC  
• Long battery life with low power consumption  
—<1µA max standby current  
—<400µA max active current during read  
• 32Kbits of EEPROM  
• Built-in inadvertent write protection  
Power-up/power-down protection circuitry  
—Protect 0, 1/4, 1/2 or all of EEPROM array with  
Block Lockprotection  
Applying power to the device activates the power on  
reset circuit which holds RESET/RESET active for a  
period of time. This allows the power supply and oscilla-  
tor to stabilize before the processor can execute code.  
The device’s low V  
detection circuitry protects the  
CC  
user’s system from low voltage conditions by holding  
RESET/RESET active when V falls below a mini-  
CC  
—In circuit programmable ROM mode  
• 2MHz SPI interface modes (0,0 & 1,1)  
• Minimize EEPROM programming time  
—32-byte page write mode

lizes. Five industry standard V  
thresholds are  
TRIP  
available, however, Xicor’s unique circuits allow the  
threshold to be reprogrammed to meet custom  
requirements or to fine-tune the threshold in applica-  
tions requiring higher precision.  
—Self-timed write cycle  
—5ms write cycle time (typical)  
• 2.7V to 5.5V and 4.5V to 5.5V power supply
