SPI-Compatible RTC in a TDFN  
General Description  
Features  
♦ Real-Time Clock Counts Seconds, Minutes, Hours,  
The MAX6902 SPI™-compatible real-time clock con-  
tains a real-time clock/calendar and 31 x 8 bits of static  
random-access memory (SRAM). The real-time  
clock/calendar provides seconds, minutes, hours, day,  
date, month, year, and century information. A time/date  
programmable polled ALARM is included in the  
MAX6902. The end-of-the-month date is automatically  
adjusted for months with fewer than 31 days, including  
corrections for leap year up to the year 2100. The clock  
operates in either the 24hr or 12hr format with an  
AM/PM indicator. The MAX6902 operates with a supply  
voltage of +2V to +5.5V, is available in the ultra-small  
8-pin TDFN package, and works over the -40°C to  
+85°C industrial temperature range.  
Day of Week, Date of Month, Month, Year, and Century  
♦ Leap-Year Compensation Valid up to Year 2100  
♦ +2V to +5.5V Wide Operating Voltage Range  
♦ SPI Interface: 4MHz at 5V; 1MHz at 2V  
♦ 31 x 8-Bit SRAM for Scratchpad Data Storage  
♦ Uses Standard 32.768kHz, 12.5pF Watch Crystal  
♦ Low Timekeeping Current (400nA at 2V)  
♦ Single-Byte or Multiple-Byte (Burst Mode) Data  
Transfer for Read or Write of Clock Registers or  
SRAM  
♦ Ultra-Small 8-Pin 3mm x 3mm x 0.8mm TDFN  
Package  
♦ Programmable Time/Date Polled ALARM Function  
♦ No External Crystal Bias Resistors or Capacitors
