I Version determined by laser trimming: These chips are produced from a common device by the laser trimming of fuses corresponding to the ordered version, shown in table 1. These devices are shipped for electrical characteristics testing. Laser-trimmed versions are identified externally by the combination of the version name marking (1) and the locations of trimmed fuses (2). I Version determined by mask pattern: These chips are fabricated using the mask corresponding to the ordered version, and do not require trimming. Mask-fabricated versions are identified externally by the version name marking (1) only. Since the WF5027 series devices are manufactured using 2 methods, there are 2 types of IC chip available (identified externally) for the same version name. The identification markings for all WF5027 series device versions is shown in table 2.

Output switching waveform VIH VIL INHN tOD 0.1V tSTR Q Normal operation Output stopped Hi-Z* Normal operation When INHN goes HIGH to LOW, the Q output goes HIGH once and then becomes high impedance. When INHN goes LOW to HIGH, the Q output goes from high impedance to normal output operation when the oscillation starts (oscillation is detected). *) The high-impedance interval in the figure is shown as a LOW level due to the 1kΩ pull-down resistor connected to the Q pin (see "Measurement circuit 2" in the "Measurement Circuits" section).

INHN HIGH (or open) LOW Q Frequency output High impedance Oscillator Normal operation Stopped Power-saving Pull-up Resistor The INHN pin pull-up resistance RUP1 or RUP2 changes in response to the input level (HIGH or LOW). When INHN is tied LOW level, the pull-up resistance is large (RUP1), reducing the current consumed by the resistance. When INHN is left open circuit, the pull-up resistance is small (RUP2), which increases the input susceptibility to external noise. However, the pull-up resistance ties the INHN pin HIGH level to prevent external noise from unexpectedly stopping the output. Oscillation Detector Function The WF5027 series also feature an oscillation detector circuit. This circuit functions to disable the outputs until the oscillator circuit starts and oscillation becomes stable. This alleviates the danger of abnormal oscillator output at oscillator start-up when power is applied or when INHN is switched.
