The Bootloader is a ROM-based application that provides the following features:
The bootloader manages communication according to a specifically defined protocol to provide
the whole access and service on Flash memory. Furthermore, all accesses and routines can be
called from the user application.

• Flash EEPROM Internal Program Memory
• Boot vector allows user provided Flash loader code to reside anywhere in the Flash memory
• Default loader in Boot ROM allows programming via the serial port without the need of a user
• Programming and erasing voltage with standard power supply
• Read/Programming/Erase:
• Typical programming time (64K bytes) is 22s with on chip serial bootloader
• Programmable security for the code in the Flash
• 100K write cycles
• 10 years data retention
space. This configuration provides flexibility to the user.
