■Application Note
■FUNCTIONAL DESCRIPTION •Standby Function
When CONT Terminal is “Low”, the FOUT Terminal output is High impedance.
CONT FOUT Oscillator High(Open) Frequency output Normal operation Low High impedance Stop
When not using Stand-by function, CONT terminal is recommended to connect to VDD.
•Built-in Variable Pull-up Resistance of CONT terminal The built-in pull-up resistance value of CONT Terminal changes in response to the input level. When CONT is “Low” level, the pull-up resistance value is large to reduce the current consumption by the resistance. When CONT is open or
connected to VDD, the pull-up resistance value is small to decrease the input susceptibility to external noise. It works to prevent an unexpectedly stopping of the output by external noise.
•VIRSION DISCRIMINATION INTERNAL COMPONENTS PAD layout version of the NJU6222 series is determined by the version name in chip. Divide version of the NJU6222 series is determined by the internal fuse trimming.
Laser-trimmed versions are identified externally by the combination of the version name marking (1) and the locations of trimmed fuses (2). (Table 1 shows the chip version identification)
