"Description: DS3234 is a low cost, high accuracy, real-time clock (RTC). It adopts SPI? bus, integrated temperature compensated crystal oscillator (TCXO) and crystal. DS3234 is set with precision voltage reference after temperature compensation, and a comparator circuit to monitor VCC. When the VCC is below the power failure (VPF), the device output /RST; When VCC is below in both VPF and VBAT, the device will be banned from the read/write access. The device also monitors /RST pin, and can be used as μP reset input button. When the device's main power supply is disconnected, the device switch to backup power input to maintain precise timing. Integrated crystal resonator enhances the long-term accuracy and reduces the number of parts. DS3234 provides commercial grade and industrial grade temperature range, and adopt industry standard 300mil, SO package for 20 pins. DS3234 adopts 256 byte SRAM battery backup. When the main power is down, the power connected to VBAT pin enables the content of the RAM to be maintained. The RTC can count seconds, minutes, hours, weeks, months and provide year information. For months less than 31 days, the device can adjust automatically at the end of the month. It's also equiped with leap year correction function. The clock have 24 hours or 12 hours with/AM/PM indicator system mode. It provides two programmable timed alarms everyday and 1 contact for programmable square wave output. Address and data can be parallel transfered by SPI bidirectional bus · accuracy: ±3.5ppm with temperature range of 0°C to + 40°C · battery backup for uninterrupted timing · working temperature range Industrial grade: to 40 ° C to + 85 ° C Commercial grade: 0 ° C to + 70 ° C · low power consumption, · real time clock counting seconds, minutes and, hours, weeks, months and provide year information, has leap year conrection until year 2099 · provide two timing alarms every day · programmable square wave output · 4MHZ SPI interface, support mode 1 and
