Infineon Technologies MB91F467SAPMC-GSK5E2

Overview

MB91F467SAPMC-GSK5E2 from Cypress Semiconductor is a 32-bit FR60 RISC microcontroller designed for automotive and industrial embedded control requiring real-time processing, LIN/CAN communication, and APIX®-enabled display interconnect. It operates at up to 100 MHz core frequency, integrates 2 CAN channels (1 Mbps), 6 LIN-USARTs, 3 I²C interfaces (400 kbps), and a 10-bit 16-channel ADC with 1 μs conversion time.

For engineers reviewing the MB91F467SAPMC-GSK5E2 datasheet, MB91F467SAPMC-GSK5E2 pinout, MB91F467SAPMC-GSK5E2 application, or MB91F467SAPMC-GSK5E2 equivalent, key selection criteria include its LQFP-176 package, -40°C to +105°C operating range, dual-clock supervision (main 4 MHz/sub 32 kHz), and integrated APIX® controller supporting 105 Mbit/s automotive serial links.

Technical Context

The MB91F467SAPMC-GSK5E2 implements the FR60 CPU core with five-stage pipeline, Harvard architecture, and instruction-level multiplier support-enabling 1-instruction-per-cycle execution for embedded C code. Its interrupt latency is fixed at 6 cycles across 16 priority levels, and it supports simultaneous program/data access via separate buses.

Internal peripherals include a 5-channel DMAC with full 32-bit addressing and 8/16/32-bit transfer size selection, two independent clock supervisors monitoring both main and sub-oscillators, and an alarm comparator with programmable voltage thresholds for system-level power monitoring.

FAQ

What is the maximum operating frequency of the FR60 core in MB91F467SAPMC-GSK5E2?

The FR60 core operates at a maximum frequency of 100 MHz (CLKB), confirmed in the CY91460S datasheet Rev. *B, Page 4, Product Lineup table. This frequency is achieved using the internal PLL with 25× multiplication of the 4 MHz main oscillator, and is validated across the full -40°C to +105°C temperature range.

Does MB91F467SAPMC-GSK5E2 support CAN FD or only classical CAN?

MB91F467SAPMC-GSK5E2 implements C-CAN controllers compliant with ISO 11898-1:2015 for classical CAN only, with a maximum bit rate of 1 Mbps. It does not support CAN FD features such as flexible data-rate or extended data length, as confirmed in the peripheral resource list on Page 2 of the datasheet.

How many independent clock domains does MB91F467SAPMC-GSK5E2 provide?

The device provides three independent clock domains: CLKB (core bus, up to 100 MHz), CLKP (peripheral bus, up to 50 MHz), and CLKCAN (CAN interface, up to 40 MHz), each with dedicated prescalers and gating controls. This separation allows dynamic power optimization by disabling unused peripheral clocks without affecting core operation.

Is the APIX® controller in MB91F467SAPMC-GSK5E2 compatible with INOVA Semiconductors' latest APIX3 standard?

No-the integrated APIX® controller implements the original APIX® specification (105 Mbit/s / 6 Mbit/s link rates) as defined in the CY91460S datasheet Page 38. It is not backward-compatible with APIX3 features such as HDR video transport, embedded audio, or sideband channel extensions.
