General Description

memory until after VCC returns valid.  
The CMOS bq4011 is a nonvolatile  
262,144-bit static RAM organized as  
32,768 words by 8 bits. The integral  
control circuitry and lithium energy  
source provide reliable nonvolatility  
coupled with th e unlim ited write  
cycles of standard SRAM.  
power  
The bq4011 uses an extremely low  
s t a n dby cu r r en t CMOS SRAM,  
coupled with a small lithium coin cell  
to provide nonvolatility without long  
write-cycle times and the write-cycle  
limitations associated with EEPROM.  
Automatic write-protection

cycles

monitors the single 5V supply for an  
ou t -of-t oler a n ce con dit ion . Wh en  
VCC falls out of tolerance, the SRAM  
is unconditionally write-protected to  
prevent inadvertent write operation.  
The bq4011 requires no external cir-  
cuitry and is socket-compatible with  
industry-standard SRAMs and most  
EPROMs and EEPROMs.
