TI's New Low Energy, Real-Time Reduces clock module

A completely new low energy, real-time getting a CPU supervisor and non-volatile SRAM control from Texas Instruments (TI) offers designers a really integrated device that requires fewer than fifty percent in the board space from the traditional through-hole oral appliance 45 percent less space than surface mount solutions. Furthermore, the system combines a period of time-of-day clock together with a hundred years-based calendar which is offered in many packages getting a 2-piece SNAPHAT(TM) module, which causes it to be perfect for any tale- and understanding-communications programs, for instance modems, modems, Internet service provider servers, cell phone base stations and network remote controls.

"TI's bq4802 is beneficial to individuals programs because of the top amount of system integration and packaging technology, enabling reduced system size that has been enhanced system design flexibility," mentioned Garry Elder, product manager, Portable Energy Products, TI.

By utilizing conditioned nick-enable output and battery current output hooks, the bq4802 can write-safeguard making nonvolatile exterior SRAMs connected having a density. The system includes a backup cell to energy the particular-time and keeps valid SRAM information without needing a technique supply current. The bq4802 offers direct connection for just about any 32.768KkHz quarto movement very together with a 3V backup battery, which are put in the SNAPHAT package on top. Abilities in the device add a built-in watchdog timer that monitors the processor operation and could create a system totally reset when the error happens additionally to help system interrupts with various clock alarm or periodic alarm designs.

Availability, Packaging, Prices

The bq4802 could be acquired now from TI which is approved entrepreneurs and may be bought in the 5.0V or 3.3V version too as with a 28-pin SOIC or 28-pin TSSOP package. The plethora of packages will probably be extended while using SNAPHAT version, that's planned to become proven in 1Q 2002. To complete the SNAPHAT module, the bq48SH-28x6, which houses the backup battery and RTC very, is required.

Suggested resale prices for your bq4802 IC starts at $2.35 in amounts of a single. The Two-piece SNAPHAT module will probably be available starting with $7.00 in amounts of a single.

Texas Instruments Incorporated might be the planet leader in digital signal processing and analog technologies, the semiconductor engines from the web age. Their companies have sensors and controls, and academic and productivity solutions. TI relies in Dallas, Texas, and contains manufacturing or sales methods in than 25 nations.
