INS5609
INS5609
INS5609 is an I2C bus interface real-time clock with low power consumption. It embeds a 32.768KHz TCXO. The high precise temperature sensor and temperature compensated circuit ensure the high clock accuracy. It supports calendar (year, month, day, hour, minute, second), clock and timer functions etc. The SMD3225 package with only 1.0mm thickness makes it very suitable to be used in portable and small size electronic devices.
