Abracon Introduces Ultra Low Power Real-Time-Clock Integrated Circuits

“Both AB08XX and AB18XX devices are offered with either SPI or I2C interface with up to 256 bytes of on-board RAM. Furthermore, the AB18XX devices are offered with an on-board Power Switch to control the power port of system processor/µcontroller; thereby, eliminating leakage currents,” continues Raza.

Since RTC ICs have broad applications, these low cost, ultra low power solutions are ideal for all power sensitive designs such as: Coin-cell and Other Battery Powered Hand-held Solutions, Smart Grid Meters, Smart Cards, Wireless Sensors and Tags, Medical Electronics, Patient Monitoring, Utility Meters, Data Loggers, Appliances, Handsets and Other General Purpose Consumer Electronics.

Key features of this family include:

-An ultra low supply current:
-Less than 15nA with RC Oscillator
-Less than 20nA with RC Oscillator & Auto Calibration
-Less than 55nA with Crystal Oscillator
-Operating voltage: +1.70V to +3.60V
-An industry standard: 3x3mm QFN package
-I2C (400kHz) or SPI (2MHz) communication
-Counters for hundreds, seconds, minutes, hours, date, weekday, month, year and century
-Alarm capability on all counters
-A watchdog timer with hardware reset
-Up to 256 bytes of general purpose RAM
-Power management: Integrated less than 1Ω power switch for off-chip components, such as the host MCU

These solutions are currently in stock with Abracon's Global Distribution partners at a competitive distribution resale price.
