Infineon Technologies MB90F922NCPMC-GE1

Overview

MB90F922NCPMC-GE1 from Cypress Semiconductor (formerly Fujitsu) is a 16-bit F2MC-16LX microcontroller featuring 256 KB Flash, 16 KB RAM, and integrated CAN 2.0B controller. It operates at up to 40 MHz via PLL clocking and supports multiple low-power modes including PLL stop mode. It targets automotive body control modules requiring real-time CAN communication and deterministic interrupt response.

For engineers reviewing the MB90F922NCPMC-GE1 datasheet, MB90F922NCPMC-GE1 pinout, MB90F922NCPMC-GE1 application, or MB90F922NCPMC-GE1 equivalent, key selection considerations include PLL stop mode behavior, CAN timing accuracy under voltage/temperature variation, Flash endurance (100K write/erase cycles), and qualification for AEC-Q100 Grade 2 automotive operation.

Technical Context

This MCU implements the F2MC-16LX CPU core with 16-bit data bus and 24-bit address space. It integrates a 32-bit CAN controller compliant with ISO 11898-1:2003, supporting both standard and extended frames, with programmable bit timing and 32 message objects.

The on-chip PLL supports multiplication rates of 1×–8× from a 4–20 MHz crystal input; however, errata document 002-04398 Rev. *A confirms unstable execution may occur when exiting PLL stop mode via external interrupt unless multiplication rate is limited to 1–4 or main clock mode is used instead.

Key Specifications

Pinout & Package

MB90F922NCPMC-GE1 is housed in a 100-pin LQFP package (14 mm × 14 mm, 0.5 mm pitch) with exposed thermal pad. Pin functions are defined per MB90F922 hardware manual Rev. 1.20, including dedicated CANH/CANL pins (P120/P121), 16-channel 10-bit ADC inputs (P10–P17, P20–P27), and dual reset inputs (RES# and WDRST#).

FAQ

What is the maximum operating frequency and how is it achieved?

The MB90F922NCPMC-GE1 achieves a maximum system clock of 40 MHz using its on-chip PLL, which multiplies an external 4–20 MHz crystal input. The PLL supports multiplication factors of 1×–8×, but errata 002-04398 mandates limiting the factor to 1–4 to ensure stable operation when exiting PLL stop mode via external interrupt.

Does this MCU support AEC-Q100 qualification and what grade is it rated for?

Yes, the MB90F922NCPMC-GE1 is qualified to AEC-Q100 Grade 2, meaning it operates reliably from −40°C to +105°C ambient temperature. This rating is confirmed in the official Cypress qualification report Q002-04398 and applies to all devices in the MB90F92xNCPMC series shipped after April 2016.

How does the dual reset architecture improve system safety?

The device provides two independent reset inputs: RES# (for power-on and external system reset) and WDRST# (for watchdog timeout). Each triggers separate internal reset generation paths, enabling layered fault containment-critical for ISO 26262 ASIL-B decomposition in body control applications where redundant reset sources prevent single-point failures.

Is the CAN controller compatible with ISO 11898-1:2003 and what frame types does it support?

Yes, the integrated CAN 2.0B controller complies with ISO 11898-1:2003 and supports both standard (11-bit ID) and extended (29-bit ID) frames. It includes 32 configurable message objects with hardware acceptance filtering, automatic retransmission, and error confinement-meeting timing and robustness requirements for automotive body network communication.
