REAL-TIME CLOCK
RP/RF/RJ5C15
OUTLINE
NO. EK-086-9908
The RP/RF/RJ5C15 are real-time clocks for microcomputers that can be connected directly to data buses of
16bit CPUs, such as the 8086, Z8000, and 68000, and of 8bit CPUs, such as the 8085A, Z80, 6809, and 6502. They
allow setting or reading of the clock with the same procedures as for the Read/Write operation for memory.
These products have various features including clock, calendar and alarm functions and can be backed up by
batteries.
FEATURES
鈥?Connected directly to CPU enabling fast access.
鈥?4bit address input : A0 - A3
鈥?All clock data expressed in BCD codes
鈥?Backed up by batteries (minimum : 2.0V)
鈥?4bit bidirectional data bus : D0 - D3
鈥?Built-in clock counter (hour, minute, second) and calendar counter (leap year, year, month, day, day-of-the-week)
鈥?Selectable basic clock frequency : 16kHz, 1kHz, 128Hz, 16Hz, 1Hz, 1/60Hz.
