描述：描述
The bq4802Y/bq4802LY real-time clock is a low-power microprocessor peripheral that integrates a time-of-day clock, a century-based calendar, and a CPU supervisor, with package options including a 28-pin SOIC, TSSOP, or SNAPHAT that requires the bq48SH-28x6 to complete the two-piece module. The bq4802Y/ bq4802LY is ideal for fax machines, copiers, industrial control systems, point-of-sale terminals, data loggers, and computers.
The bq4802Y/bq4802LY provides direct connections for a 32.768-kHz quartz crystal and a 3-V backup battery. Through the use of the conditional chip enable output (CE\OUT) and battery voltage output (VOUT) pins, the bq4802Y/bq4802LY can write-protect and make non- volatile external SRAMs. The backup cell powers the real-time clock and maintains SRAM information the absence of system voltage. The crystal and battery are contained within the modules for a more integrated solution.
The bq4802Y/bq4802LY contains a temperature-compensated reference and comparator circuit that monitors the status of its voltage supply. When the bq4802Y/bq4802LY detects an out-of-tolerance condition, it generates an interrupt warning and subsequently a microprocessor reset. The reset stays active for 200 ms after VCC rises within tolerance, to allow for power supply and processor stabilization. The reset function also allows for an external push-button override.
特性
Real-Time Clock Counts Seconds Through Centuries in BCD Format
bq4802Y: 5-V Operation
bq4802LY: 3.3-V Operation
On-Chip Battery-Backup Switchover Circuit With Nonvolatile Control for External SRAM
