REAL-TIME CLOCK
S-3511A
Seiko Instruments Inc.
1
The S-3511A is a CMOS real-time clock that supplies
and sets time and calendar data when requested by the
CPU. Soft-ware processing is reduced by connecting the
CPU via 3 wires and due to an interrupt/alarm function.
The constant voltage drive of the oscillation circuit also
enables low current consumption.
Features
Low current consumption
: 0.7
A typ.(VDD = 3.0 V, Ta = 25°C)
Wide operating voltage range : 1.7 V to 5.5 V
BCD I/O of second, minute, hour, day, date, month and year
Interface to CPU with 3 lines
Built-in automatic calendar, automatic leap-year calculation up to 2099
Built-in voltage detector
Built-in constant voltage circuit
Built-in flag generation circuit during power-on and power down
Built-in alarm interrupter
Steady-state interrupt frequency/duty setting function
Built-in 32 kHz oscillation circuit (Internal Cd, External Cg and Crystal)
Applications
Cellular phone
PHS
A variety of pagers
TV set and VCR
Camera
