Product details
Overview
MB91F662PMC-G-N9E1 from Infineon Technologies is a 32-bit FR family microcontroller featuring 512 KB on-chip Flash memory, 32 KB RAM, and integrated CAN 2.0B controller with dual-channel support. It operates at up to 64 MHz, includes a 12-bit ADC (16 channels), and targets automotive body control modules requiring real-time communication and deterministic I/O handling.
For engineers reviewing the MB91F662PMC-G-N9E1 datasheet, MB91F662PMC-G-N9E1 pinout, MB91F662PMC-G-N9E1 application, or MB91F662PMC-G-N9E1 equivalent, key selection criteria include CAN interface timing compliance, Flash endurance (100k write/erase cycles), RAM retention during stop mode, and qualification per AEC-Q100 Grade 2.
Technical Context
This MCU implements Fujitsu's FR60 core architecture with Harvard memory organization and supports three low-power modes: wait, stop, and deep stop. It integrates a 32-bit timer with input capture/compare, watchdog timer with window function, and programmable clock divider for peripheral clock gating.
The CAN controller supports bit rates up to 1 Mbps, message filtering via 32 acceptance masks, and automatic retransmission on error. The ADC features hardware-triggered sampling synchronized to PWM events and supports differential input mode on selected channels.
