Infineon Technologies MB91F469QAPB-GSK6E1

Overview

MB91F469QAPB-GSK6E1 from Infineon Technologies (formerly Cypress) is a 32-bit FR60 RISC microcontroller designed for real-time embedded control in automotive and industrial systems. It operates at up to 100 MHz core frequency (at 1.9 V), integrates 3 CAN channels (1 Mbps), 12 LIN-USART channels, dual 10-bit ADCs (32 + 8 channels), and 205 general-purpose I/O ports. It supports −40°C to +105°C operation in a 320-pin BGA package.

For engineers reviewing the MB91F469QAPB-GSK6E1 datasheet, MB91F469QAPB-GSK6E1 pinout, MB91F469QAPB-GSK6E1 application, or MB91F469QAPB-GSK6E1 equivalent, this page delivers verified technical context, validated pin functions, real-world use cases, and confirmed alternative options - all grounded in the official CY91460Q Series documentation (Rev. *C, June 2019).

Technical Context

The MB91F469QAPB-GSK6E1 implements the FR60 CPU core with five-stage pipeline, 16-bit fixed-length instructions, and instruction-level multiplier support (signed 32-bit in 5 cycles). Its Harvard architecture enables concurrent program/data access, and interrupt latency is fixed at 6 cycles across 16 priority levels.

It integrates C-CAN controllers (32 message buffers per channel), LIN-USART with sync-break detection and dedicated baud rate generator, and dual successive-approximation ADCs with 1 µs minimum conversion time. Clock supervision includes main (4 MHz) and sub-clock (32 kHz) monitoring with automatic CR oscillator fallback.

Key Specifications

Pinout & Package

FAQ

What is the maximum operating frequency of the MB91F469QAPB-GSK6E1 core?

The MB91F469QAPB-GSK6E1 achieves a maximum core frequency of 100 MHz when powered by a 1.9 V main regulator (REGSEL_FLASHSEL=1 and REGSEL_MAINSEL=1). At the default 1.8 V supply, the maximum is 88 MHz. Both settings are specified in the "Product Lineup" table (page 4) of the official datasheet.

Does this MCU support CAN FD or only classical CAN?

MB91F469QAPB-GSK6E1 implements C-CAN controllers compliant with ISO 11898-1:2003 (classical CAN only), supporting up to 1 Mbps. It does not support CAN FD frame format, bit rate switching, or extended data length - confirmed in the "Internal Peripheral Resources" section (page 2) and "Product Lineup" (page 4).

How many independent ADC modules does it have, and what are their resolutions?

It contains two independent successive-approximation ADC modules: ADC0 (10-bit, 32 input channels) and ADC1 (10-bit, 8 input channels). Each has separate trigger sources, clocks, and result registers - enabling concurrent sampling without resource contention, as detailed on page 2 and page 103 of the datasheet.

Is the 320-pin BGA package lead-free and RoHS-compliant?

Yes - the BYA320 package used for MB91F469QAPB-GSK6E1 is lead-free and RoHS-compliant, consistent with Infineon's environmental policy and documented in the "Package Dimension" section (page 146) and "Sales, Solutions, and Legal Information" (page 152) of the datasheet.
