RTC8583 Datasheet, PDF (1/2 Pages) Epson ToYoCom – I2C-BUS COMPATIBLE REAL TIME CLOCK MODULE

Real time clock module
I² C-BUS COMPATIBLE REAL TIME CLOCK MODULE
RTC-8583/8593 series
• Builtin crystal unit. Adjustment free with 10pF external capacitor.
• Small package (SOP 14-pin).
• Three mode operations: internal crystal oscillation, external 50 Hz
clock and event counter.
• I²C-Bus inter face compatible.
• Builtin 240 x 8 bit S-RAM available (RTC8583).
• Alarm and timer functions available.
• Wide operating voltage range 2.5V to 6.0V.
• Wide data hold voltage range 1.0V to 6.0V.
• Low current consumption (RTC8593, 1.0µA typical).
