FEATURES

LED direct drive by time-sharing (duplex) Wide operating voltage range Alarm on a 24-hour basis Time format: 12-hour AM/PM and 24- hour On-chip RC-oscillator for battery backup 50Hz or 60Hz is usable as the reference frequency Possible to automatically advance "hours", "minutes" Sleep timer (max. 59 minutes or 1 hour 59 minutes) Repeatedly usable snooze Power failure indicator 900Hz output for alarm tone Bare chip or SOP-28 are available Pin-to-Pin replacement with Sanyo LM8560 FUNCTIONS Real time display Alarm with snooze Sleep timer (max. 59 minutes or 1 hour 59 minutes) PIN CONNECTION OPERATION DESCRIPTION 50Hz/60Hz Input: The on-chip Schmitt trigger circuit allows a simple RC filter at the input to remove possible line voltage transients. An internal pull-up resister is provided. CR Input: Then AC power-down occurs, the time counter enters the "hold" mode and the on-chip clock oscillator starts operating immediately. If there is no input at "50/60 Hz input" during 3-clock period, this oscillator controls the time counter advance instead of "50/60Hz input". The values of CR determine the frequency of the on-chip clock oscillator. All segment outputs are off during backup oscillator operation. NOTE: If the backup OSC is used at the power-down mode, "50/60Hz input" must be open or at Vss level. 50/60 select input: Connecting "50/60Hz select" to Vss enables 50Hz operation. For 60Hz operation, "50/60Hz select" is left unconnected: Pull-down to VDD is provided by the internal pulldown resister. Display mode select input (alarm display/sleep display); The internal pull-down resistor allows the use of 2 SPST (single-pole single- throw) switches to select 4 display modes listed in Table 1.

Table 1. Display Mode the seconds display mode is entered. pull-down resistor each is provided. Table 2. Display Mode "Hours" are incremented +1 immediately and advance at a 2Hz rate 1/4 to 3/4 second later. "Minutes" are incremented +1 immediately and advance at a 2Hz rate 1/4 to 3/4 second later. Both operations shown above are performed. "Seconds" are cleared to [00]. "Hours" and "Minutes" are reset to (0:00) (24hour basis) or (12:00) (12hour basis). "Hours" are incremented +1 immediately and advance at a 2Hz rate 1/4 to 3/4 second later. "Minutes" are incremented +1 immediately and advance at a 2Hz rate 1/4 to 3/4 second later. "Hours" and "Minutes" are reset to [0:00] (24-hour basis) or [12:00] (12-hour basis). The moment. VDD is applied to "sleep display", the sleep counter is set to [0:59]. is set to (1:59). The sleep counter counts down at a 2Hz rate. The sleep counter counts down at a 2Hz rate. input and "minute set" input are released.

  • 12/24-hour select input: Leaiving this pin unconnected (VDD) causes the 12-hour basis to be selected; connecting this pin to VSS causes the 24-hour basis to be selected. An internal pull- down resistor is provided.
  • Power failure indication: It the power supply voltage drops and is applied again, all the on-segments flash and the power failure indication mode is entered. The power failure indication mode is released by applying VSS to "hour set" or "minutes set”
  • Alarm operation and alarm output: When the alarm set time is reached, the alarm signal is delivered. This signal continues to be delivered for 1 hour 59 minutes unless reset by "alarm off" or "snooze input". This signal is provided for the tone-signal of 900Hz with 50% duty of 2Hz gated. A simple LPF can be used to turn this alarm signal into DC signal as required.
  • Snooze input: By momentarily connecting this pin to VSS at the alarm on-state, the alarm output is inhibited for 8 to 9 minutes, after which used repeatedly for 1 hour 59 minutes. An

internal pull-down resistor is provided. By connecting "snooze input" to VSS at the alarm off-state, the sleep timer counter is reset to [0:00]. (The sleep timer is reset with one • touch.)

  • Alarm off input: Connecting this input pin to VSS inhibits the alarm output momentarily. An internal pulldown resistor is provided.
  • Sleep timer and sleep output: The sleep output can be used to keep the radio turned on for any period of time up to 59 minutes or 1 hour 59 minutes. Table 2 shows how to select the period (59 minutes or 1 hour 59 minutes). This sleep timer uses a down counter. When the counter contents reach [00], the output stops being delivered, turning off the radio. By connecting "snooze input" to VSS at the sleep output on-state, the sleep output is inhibited.
