Caution: 1. Permanent damage to the chip may result if absolute maximum ratings are
exceeded.
2. Never apply more than 7.0 V to any of the pins of the 5- or 4-V version or 4.3 V to
any of the pins (except for port A) of the 3-V version.
Notes: 1. Power supply voltage for VCC1 pin.
Never exceed the maximum rating of V
CL
in the low-power version (3-V version)
because both the VCC1 and VCL pins are connected to the V
CL
power supply.
2. It is an operating power supply voltage pin on the chip.
Never apply power supply voltage to the VCL pin in the 5- or 4-V version.
Always connect an external capacitor between the VCL pin and ground for internal
voltage stabilization.
