The MSM62X42B is a bus-connection Microcomputer peripheral IC of a Real Time Clock with built-in crystal in the perpetual calendar which can be read and written from a second unit. The interface between this IC and a microcomputer uses 4 data buses, 4 address buses, 3 control buses and 2 chip selects and carries out setting up, amending and reading time. ALE.
• 32.768kHz built-in crystal oscillator (2 ranks of ± 10PPM and ± 50PPM --DIP) (2 ranks of ± 20PPM and ± 50PPM --SOP)
• Real time clock of second, minute, date, month, year and day of week
• Interface corresponding to microcomputer bus
• 30-second compensation controlled by software
• Periodical interrupt function (or periodical waveform output) for alarm
• STOP/START function for clock
• 12/24 hour selectable
• AEL input for 8048 system, 8051 system or 8085 system (when a microcomputer does not provide the ALE output, fix the AEL input at "H".)
• Low current consumption for CMOS device
• Low .
