Description
X1226V8ZT1 Intersil / Renesas Real Time Clock (RTC) IC Clock/Calendar I2C, 2-Wire Serial 8-TSSOP (0.173″, 4.40mm Width)
The X1226 device is a Real Time Clock with clock/calendar, two polled alarms with integrated 512×8 EEPROM, oscillator compensation, and battery backup switch. The oscillator uses an external, low-cost 32.768kHz crystal. All compensation and trim components are integrated on the chip. This eliminates several external discrete components and a trim capacitor, saving board area and component cost.
