SLUS118AMAY 1999REVISED MAY 2007  
32 k × 8 NONVOLATILE SRAM (5 V, 3.3 V)  
FEATURES  
GENERAL DESCRIPTION  
Data Retention for at least 10 Years Without  
Power  
The CMOS bq4011/Y/LY 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 the  
unlimited write cycles of standard SRAM.  
Automatic Write-Protection During  
Power-up/Power-down Cycles  
Conventional SRAM Operation, Including  
Unlimited Write Cycles  
The control circuitry constantly monitors the single  
supply for an out-of-tolerance condition. When VCC  
falls out of tolerance, the SRAM is unconditionally  
write-protected to prevent an inadvertent write  
operation.  
Internal Isolation of Battery before Power  
Application  
5-V or 3.3-V Operation  
Industry Standard 28-Pin DIP Pinout  
At this time the integral energy source is switched on  
to sustain the memory until after VCC returns valid.  
The bq4011/Y/LY uses extremely low standby  
current CMOS SRAMs, coupled with small lithium  
coin cells to provide nonvolatility without long  
write-cycle times and the write-cycle limitations  
associated with EEPROM.  
The bq4011/Y/LY requires no external circuitry and is  
compatible with the industry-standard 256-kb SRAM  
pinout.
