Caution: Permanent damage may occur to the chip if maximum ratings are exceeded. Normal
operation should be under the conditions specified in Electrical Characteristics.
Exceeding these values can result in incorrect operation and reduced reliability.
Notes: 1. A voltage not lower than V
CC
must be applied as LCD power supply voltage V
LCD
.
2. 12 V must not be applied to the FWE pin, as this will permanently damage the device.
3. When the built-in op-amps are not used, and the LCD drive voltages are supplied
directly from an external source, this applies to V1OUT, V2OUT, V3OUT, V4OUT, and
V5OUT.
4. The operating temperature range when programming/erasing flash memory is: T
a
= 0°C
to +75°C.
