Infineon Technologies MB90F922NCSPMC-GSE1

Overview

MB90F922NCSPMC-GSE1 from Cypress Semiconductor is a 16-bit F2MC-16LX microcontroller featuring 256 KB Flash, 16 KB RAM, PLL-based clock generation (×1–×8), 32-bit timer/counter, and CAN 2.0B interface. It operates at up to 40 MHz and targets automotive body control modules requiring deterministic real-time response and low-power stop modes.

For engineers reviewing the MB90F922NCSPMC-GSE1 datasheet, MB90F922NCSPMC-GSE1 pinout, MB90F922NCSPMC-GSE1 application, or MB90F922NCSPMC-GSE1 equivalent, key selection considerations include PLL stop mode errata mitigation, CAN timing tolerance under clock instability, Flash endurance (100K cycles), and package-specific thermal derating for 100-pin LQFP.

Technical Context

This MCU implements the F2MC-16LX core with Harvard architecture, supporting instruction fetch from Flash and data access from RAM in parallel. It integrates a 3-channel 16-bit PWM generator with dead-time control, 12-bit ADC (16 channels, 1.25 µs conversion), and dual CAN controllers with message object buffers and automatic retransmission.

The device uses an on-chip PLL with programmable multiplication factor (1×–8×) and supports three low-power modes: HALT, STOP, and PLL STOP - though PLL STOP requires workaround per Errata 002-04398 Rev. *A due to potential unstable clock resumption after external interrupt wake-up.

Key Specifications

Pinout & Package

MB90F922NCSPMC-GSE1 is housed in a 100-pin LQFP package with exposed thermal pad (EP), compliant with JEDEC MS-026. Pin functions are defined per the MB90F922 hardware manual (Rev. 1.2), including dedicated CANH/CANL differential I/Os, multiplexed 16-bit address/data bus, and dedicated reset/watchdog inputs.

FAQ

What is the recommended workaround for the PLL STOP mode errata?

The documented workaround requires transitioning through main clock mode before re-entering PLL mode: PLL → main clock → main stop → main clock → PLL. This avoids unstable clock resumption after external interrupt wake-up. The sequence must be implemented in firmware prior to entering PLL STOP, and is validated in Errata 002-04398 Rev. *A.

Does MB90F922NCSPMC-GSE1 support CAN FD?

No. MB90F922NCSPMC-GSE1 implements CAN 2.0B protocol only, with fixed 11-bit identifier support and bit rates up to 1 Mbps. It lacks CAN FD features such as flexible data-rate switching, extended data length (up to 64 bytes), and CRC separation - these require newer-generation CAN IP not present in the F2MC-16LX peripheral set.

Is the 100-pin LQFP package RoHS-compliant and lead-free?

Yes. MB90F922NCSPMC-GSE1 uses a lead-free, RoHS-compliant 100-pin LQFP package (Pb-free solder finish, halogen-free molding compound) meeting JEDEC J-STD-020D moisture sensitivity level 3 and IPC/JEDEC J-STD-033 handling requirements.

Can the on-chip Flash be programmed in-system via CAN or UART?

No. In-system programming requires the SWD debug interface and Cypress-provided bootloader tools. CAN and UART are data communication interfaces only; they lack dedicated flash programming command sets or secure boot ROM access. Field updates must use external programmer or pre-integrated SWD-enabled firmware updater.
