CAUTION: Exposure to ultraviolet (UV) light can degrade the data stored in EEPROM cells. Therefore,

customers who use a WLCSP package or the product at a die level must ensure that exposure to ultraviolet

light does not occur.

Microchip Devices Code Protection Feature

Note the following details of the code protection feature on Microchip devices:

• Microchip products meet the specifications contained in their particular Microchip Data Sheet.

• Microchip believes that its family of products is secure when used in the intended manner and under normal

conditions.

• There are dishonest and possibly illegal methods being used in attempts to breach the code protection features

of the Microchip devices. We believe that these methods require using the Microchip products in a manner
