The integral control circuitry and lithium energy source provide reliable nonvolatility coupled with the unlimited write cycles of standard SRAM. 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. 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-Mb SRAM pinout.

During power-down and power-up cycles, the bq4010/Y/LY acts as a nonvolatile memory, automatically protecting and preserving the memory contents. Power-down/power-up control circuitry constantly monitors the VCC supply for a power-fail-detect threshold VPFD. The bq4010 monitors for VPFD = 4.62 V typical for use in 5-V systems with 5% supply tolerance. The bq4010Y monitors for VPFD = 4.37 V typical for use in 5-V systems with 10% supply tolerance. The bq4010LY monitors for VPFD = 2.90 V (typ) for use in 3.3-V systems. When VCC falls below the VPFD threshold, the SRAM automatically write-protects the data. All outputs become high impedance, and all inputs are treated as don't care. If a valid access is in process at the time of power-fail detection, the memory cycle continues to completion. If the memory cycle fails to terminate within time tWPT, write-protection takes place. As VCC falls past VPFD and approaches VSO, the control circuitry switches to the internal lithium backup supply, which provides data retention until valid VCC is applied. When VCC returns to a level above the internal backup cell voltage, the supply is switched back to VCC. After VCC ramps above the VPFD threshold, write-protection continues for a time tCER (120 ms maximum in 5-V system, 85 ms maximum in 3.3-V system) to allow for processor stabilization. Normal memory operation may resume after this time. The internal coin cells used by the bq4010/Y/LY have an extremely long shelf life and provide data retention for more than 10 years in the absence of system power. As shipped from TI, the integral lithium cells of the MT-type module are electrically isolated from the memory. (Self-discharge in this condition is approximately 0.5% per year.) Following the first application of VCC, this isolation is broken, and the lithium backup provides data retention on subsequent power-downs. The LIFETIME LITHIUM package option is shipped as two devices, which must be ordered separately.

TI is not responsible or liable for any such statements. TI products are not authorized for use in safety-critical applications (such as life support) where a failure of the TI product would reasonably be expected to cause severe personal injury or death, unless officers of the parties have executed an agreement specifically governing such use. Buyers represent that they have all necessary expertise in the safety and regulatory ramifications of their applications, and acknowledge and agree that they are solely responsible for all legal, regulatory and safety-related requirements concerning their products and any use of TI products in such safety-critical applications, notwithstanding any applications-related information or support that may be provided by TI. Further, Buyers must fully indemnify TI and its representatives against any damages arising out of the use of TI products in such safety-critical applications. TI products are neither designed nor intended for use in military/aerospace applications or environments unless the TI products are specifically designated by TI as military-grade or "enhanced plastic." Only products designated by TI as military-grade meet military specifications. Buyers acknowledge and agree that any such use of TI products which TI has not designated as military-grade is solely at the Buyer's risk, and that they are solely responsible for compliance with all legal and regulatory requirements in connection with such use. TI products are neither designed nor intended for use in automotive applications or environments unless the specific TI products are designated by TI as compliant with ISO/TS 16949 requirements. Buyers acknowledge and agree that, if they use any non-designated products in automotive applications, TI will not be responsible for any failure to meet such requirements.
