4 / 60 page R2061x NO.EA-112-160701 4 * R2061K (FFP12) is the discontinued product as of July, 2016. PIN DESCRIPTION Symbol Item Description CE Chip enable Input The CE pin is used for interfacing with the CPU. Should be held high to allow access to the CPU. Incorporates a pull-down resistor. Should be held low or open when the CPU is powered off. Allows a maximum input voltage of 5.5 volts regardless of supply voltage. SCLK Serial Clock Input The SCLK pin is used to input clock pulses synchronizing the input and output of data to and from the SIO pin. Allows a maximum input voltage of 5.5 volts regardless of supply voltage. SIO Serial Input / Output The SIO pin is used to input or output data intended for writing or reading in synchronization with the SCLK pin. INTR Interrupt Output The INTR pin is used to output alarm interrupt (Alarm_W) and alarm interrupt (Alarm_D) and output periodic interrupt signals to the CPU signals. Disabled at power-on from 0V. Nch. open drain output. VCC Main Battery input Supply power to the IC. VSB Power Supply Input for Backup Battery Connect a primary battery for backup. Normally, power is supplied from VCC to the IC. If VCC level is equal or less than –VDET1, power is supplied from this pin. OSCIN OSCOUT Oscillation Circuit Input / Output The OSCIN and OSCOUT pins are used to connect the 32.768-kHz quartz crystal unit (with all other oscillation circuit components built into the R2061x). VDD Positive Power Supply Input The VDD pin is connected to the power supply. Connect a capacitor as much as 0.1 F between VDD and VSS. In the case of using a secondary battery, connecting the secondary battery to this pin is possible. VDCC VCC Power Supply Monitoring Result Output While monitoring VCC Power supply, if the voltage is equal or lower than –VDET1, this output level is “L”. When VDCC becomes “L”, SW1 turns off and SW2 turns on. As a result, power is supplied from VSB pin to the internal real time clock. When VCC is equal to +VDET1 or more, SW1 turns on and SW2 turns off. After t DELAY passed, VDCC output becomes off, or “H”. Nch Open-drain output. CIN Noise Bypass Pin To stabilize the internal reference, connect a capacitor as much as 0.1uF between this pin and VSS. VSS Negative Power Sup Supply Input The VSS pin is grounded. N.C.
