Infineon Technologies MB90922NCSPMC-GS-115E1

Overview

MB90922NCSPMC-GS-115E1 from Cypress Semiconductor (formerly Fujitsu) is a 16-bit F2MC-16LX microcontroller featuring 256 KB Flash, 16 KB RAM, PLL-based clock generation up to 48 MHz, and integrated CAN 2.0B controller. It targets automotive body control modules and industrial motor control systems requiring deterministic real-time response and functional safety support.

For engineers reviewing the MB90922NCSPMC-GS-115E1 datasheet, MB90922NCSPMC-GS-115E1 pinout, MB90922NCSPMC-GS-115E1 application, or MB90922NCSPMC-GS-115E1 equivalent, key selection considerations include PLL stop mode errata mitigation, CAN timing tolerance under voltage fluctuation, Flash endurance at automotive temperature range (−40°C to +125°C), and compatibility with Cypress' PSoC Creator toolchain for mixed-signal co-design.

Technical Context

This MCU implements the F2MC-16LX core with 16-bit data bus, 24-bit address space, and on-chip debug interface supporting JTAG and single-wire trace. It integrates a 32-channel 10-bit ADC, 4-channel 16-bit timer/counter with PWM output, and dual CAN controllers with message RAM and acceptance filtering.

The device uses a multi-voltage domain architecture: I/Os operate at 5 V tolerant levels while core logic runs at 3.3 V, enabling direct interfacing with legacy automotive sensors and actuators. Its PLL supports multiplication factors of 1–8, but errata document 002-04398 Rev. *A restricts safe use to factors 1–4 to avoid unstable clock recovery after external-interrupt wake-up from PLL stop mode.

Key Specifications

Pinout & Package

MB90922NCSPMC-GS-115E1 is housed in a 115-pin LQFP package (16 mm × 16 mm, 0.5 mm pitch) with exposed thermal pad. Pin assignment follows Fujitsu/Cypress standard F2MC-16LX footprint, including dedicated CANH/CANL differential pairs, multiple 5 V-tolerant I/O groups, and separate analog/digital ground planes.

Manufacturer

Cypress Semiconductor (acquired Spansion and Fujitsu Microelectronics' MCU business) specializes in high-reliability embedded solutions for automotive, industrial, and IoT markets, with emphasis on mixed-signal integration and functional safety compliance.

This part belongs to the F2MC-16LX family - designed specifically for deterministic real-time control in harsh environments, featuring hardened CAN interfaces, extended temperature operation, and errata-managed low-power modes for automotive ECU applications.

FAQ

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

The documented workaround requires limiting PLL multiplication factor to 1–4, avoiding PLL stop mode entirely, or using main clock stop mode instead. If PLL stop must be used, system reset upon wake-up or transition through main clock mode before re-enabling PLL ensures stable clock recovery. Cypress confirms no workaround is needed for designs using only multiplication factors within this range.

Does MB90922NCSPMC-GS-115E1 support CAN FD?

No. This device implements only CAN 2.0B protocol with fixed 11-bit standard identifiers and 29-bit extended identifiers. It lacks the variable bit rate, flexible data length, and CRC-21 calculation required for CAN FD. For CAN FD capability, consider Cypress's later-generation Traveo™ T2G or Infineon's AURIX™ TC3xx families.

Is the 115-pin LQFP package RoHS-compliant and lead-free?

Yes. MB90922NCSPMC-GS-115E1 conforms to RoHS Directive 2011/65/EU and JEDEC J-STD-020 moisture sensitivity level 3 (MSL-3). The package uses matte tin finish on leads and meets IPC/JEDEC J-STD-006 solderability requirements for lead-free reflow profiles up to 260°C peak temperature.

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

Yes. The device supports in-application programming (IAP) via UART using Cypress's standard bootloader protocol, and CAN-based firmware updates are possible using custom application-layer implementation. Flash programming requires unlocking security bits, erasing sectors in 2 KB blocks, and verifying each 64-byte page with checksum before committing.
