NXP Semiconductors PCA2125

The PCA2125 is a CMOS real-time clock/calendar optimized for low-power consumption and an operating temperature up to 125 °C. Functional description The PCA2125 contains sixteen 8-bit registers with an auto-incrementing address register, an on-chip 32.768 kHz oscillator with one integrated capacitor, a frequency divider which provides the source clock for the Real-Time Clock (RTC), a programmable clock output, and a 6 MHz...
