The integral control circuitry and lithium energy source • Automatic Write-Protection During provide reliable nonvolatility coupled with the Power-up/Power-down Cycles unlimited write cycles of standard SRAM. • Conventional SRAM Operation, Including The control circuitry constantly monitors the single Unlimited Write Cycles supply for an out-of-tolerance condition. When VCC • Internal Isolation of Battery before Power falls out of tolerance, the SRAM is unconditionally Application write-protected to prevent an inadvertent write • 5-V or 3.3-V Operation 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 bq4010/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 bq4010/Y/LY requires no external circuitry and is compatible with the industry-standard 64-Kb SRAM pinout.
