PREFACE
■Objectives and intended reader
Thank you for purchasing Fujitsu Microelectronics products.
The MB90460/465 series was developed as a group of general-purpose models in the F2MC-16LX Family,
which is a family of original 16-bit single-chip microcontrollers that can be used for application specific ICs
(ASICs).
This manual is intended for engineers who design products using the MB90460/465 series of
microcontrollers. The manual describes the functions and operation of the MB90460/465 series.
Note: F2MC is a registered of Fujitsu Microelectronics Limited and stands for FUJITSU Flexible Microcontroller.
