R5F109GCKFB

The successors to the 78K0R and R8C, with the industry's lowest level of consumption current. Automotive general-purpose low-end microcontrollers with various built-in functions necessary for automotive application communications and implementing functional safety.

OVERVIEW

RL78/F12 microcontrollers are available in a 20 to 64-pin, 8 to 64 KB flash memory lineup, and realize the industry's lowest level of consumption current. They have a built-in LIN module as an automotive interface. With various built-in functions for realizing functional safety including flash memory CRC calculation, illegal memory access detection, RAM guard, A/D converter testing, and SFR guard, a highly reliable system can be built, so these microcontrollers can be used for industrial applications and of course automotive applications.
