RX4901CEXSA0 RX4901CE REAL TIME CLOCK MODULE (SPI-Bus)
■Interface type : 3 wire / 4 wire SPI-Bus
■High stability
▲XS :
◆±3.0 x 10⁻⁶ / -40 ºC to +85 ºC (Monthly rate: ±8 seconds)
◆±5.0 x 10⁻⁶ / +85 ºC to +105 ºC (Monthly rate: ±13.2 seconds)
▲XB :
◆±5.0 x 10⁻⁶ / -40 ºC to +85 ºC (Monthly rate: ±13.2 seconds)
◆±8.0 x 10⁻⁶ / +85 ºC to +105 ºC (Monthly rate: ±21 seconds)
■Time stamp function
▲Trigger source: External event (EVIN) input, voltage drop/oscillation stop status detected, command input from the host
▲Record data: 1/1024 seconds to 1 second, seconds, minutes, hours, days, months, years
▲Number of recordable events: Maximum 32 events
■Backup power supply switching function
▲The VDD and VBAT voltages are monitored to switch between Normal mode (VDD operation) and Backup mode (VBAT operation).
■Clock output (FOUT)
▲Selectable from 32.768 kHz, 1024 Hz and 1 Hz outputs
▲Output can be controlled by a register or FOE input (selectable with a register).
●Built in frequency adjusted 32.768 kHz crystal unit and DTCXO
●Interface Type : 3 wire / 4 wire SPI-Bus
●Current consumption : 240 nA / 3 V (Typ.)
●Auto power switching function : Automatically switches to backup power supply by monitoring the VDD / VBAT voltage
●Time stamp function : Maximum 32 time stamps
●Interrupt output : Wake up every hour or every minute or every second
●Alarm interruption : Day, date, hour, minute, second
●Auto repeat wakeup timer interruption
●Self-monitoring interruption : Crystal oscillation stop, VBAT low, VDD low
