Overview
¡ Semiconductor MSM6242B ¡ Semiconductor DESCRIPTION The MSM6242B is a silicon gate CMOS Real Time Clock/Calendar for use in direct busconnection Microprocessor/Microcomputer applications.
An on-chip 32.
768 KHz crystal oscillator time base is divided to provide addressable 4-bit I/O data for SECONDS, MINUTES, HOURS, DAY OF WEEK, DATE, MONTH and YEAR.
Data access is controlled by 4-bit address, chip selects (CSO, CS1), WRITE, READ, and ALE.
Control Registers www.
DataSheet4U.
com D, E and F provide for 30 SECOND error adjustment, INTERRUPT REQUEST (IRQ FLAG) and BUSY status bits, clock STOP, HOLD, and RESET FLAG bits, 4 selectable INTERRUPTS rates are available at the STD.
P MSM6242B DIRECT BUS CONNECTED CMOS REAL TIME CLOCK/CALENDAR (STANDARD PULSE) output utilizing Control Register inputs T0, T1 and the ITRPT/ STND (INTERRUPT/STANDARD).
Masking of the interrupt output (STD.
P) can be accomplished via the MASK bit.
The MSM6242B can operate in a 12/24 hour format and Leap Year timing is ...
