6 / 20 page MB94R215B 6 ■ HANDLING DEVICES 1. Preventing Latchup Latch-up may occur in a CMOS IC if a voltage greater than VCC or less than VSS is applied to an input or output pin, or if an above-rating voltage is applied between VCC and VSS. A latchup, if it occurs, significantly increases the power supply current and may cause thermal destruction of an element. When you use a CMOS IC, be very careful not to exceed the absolute maximum rating. 2. Treatment of N.C. pins Be sure to use NC pins in open state. 3. Rising time for power supply voltage Ensure that the power supply rise time is 100 µs or less when using contact mode operation but, which may cause misoperation resulting in the corruption of FRAM data. 4. Power supply off time Ensure that the power supply off time is 1ms or longer when using contact mode operation. 5. Magnetic field strength rise time See the “■ RF INTERFACE in CONTACTLESS OPERATION” section for points to note regarding contactless operation. 6. When using both contact and contactless operation When operating in contact mode, ensure there is no RF input from the antenna. When operating in contactless mode, ensure that the contact terminals are open circuit. |
