Details
General DescriptionThe MAX6902 SPI™-compatible real-time clock contains 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.Features♦ Real-Time Clock Counts Seconds, Minutes, Hours, 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 RequiredApplications Point-of-Sale Equipment Intelligent Instruments Fax Machines Battery-Powered Products Portable Instruments
