program memory and data EEPROM are rated to
last for many thousands of erase/write cycles – up to
1K for program memory and 100K for EEPROM.
Data retention without refresh is conservatively
estimated to be greater than 40 years.
to their own program memory spaces under
internal software control. Using a bootloader
routine located in the code protected Boot Block,
it is possible to create an application that can
update itself in the field.
LF1XK50 family introduces an optional extension
to the PIC18 instruction set, which adds 8 new
instructions and an Indexed Addressing mode.
This extension has been specifically designed to
optimize re-entrant application code originally
developed in high-level languages, such as C.
module provides 1, 2 or 4 modulated outputs for
controlling half-bridge and full-bridge drivers.
Other features include:
- Auto-Shutdown, for disabling PWM outputs
- Auto-Restart, to reactivate outputs once the

communication module is capable of standard
RS-232 operation and provides support for the LIN
bus protocol. Other enhancements include
automatic baud rate detection and a 16-bit Baud
Rate Generator for improved resolution.
programmable acquisition time, allowing for a
channel to be selected and a conversion to be
initiated without waiting for a sampling period and
thus, reduce code overhead.
enhanced version incorporates a 16-bit
postscaler, allowing an extended time-out range
that is stable across operating voltage and
temperature. See
