Infineon Technologies MB91F467TAPMC-GSK5E2

Overview

MB91F467TAPMC-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 low-power operation. It operates at up to 100 MHz core frequency, integrates 2112 KB Flash, 32 KB D-RAM, dual C-CAN controllers (1 Mbps), 11 LIN-USART channels, and a 10-bit 32-channel ADC with 1 µs conversion time.

For engineers reviewing the MB91F467TAPMC-GSK5E2 datasheet, MB91F467TAPMC-GSK5E2 pinout, MB91F467TAPMC-GSK5E2 application, or MB91F467TAPMC-GSK5E2 equivalent, key selection factors include CAN/LIN coexistence, QFP-144 package compatibility, 3 V–5 V supply range, -40°C to +105°C operating temperature, and FR60 instruction set compatibility with legacy Fujitsu designs.

Technical Context

The MB91F467TA implements the FR60 CPU core with five-stage pipeline, 16-bit fixed-length instructions, and single-cycle execution for basic operations. It supports signed 32-bit multiplication in 5 cycles and interrupt response in 6 cycles across 16 priority levels.

Its peripheral set includes two C-CAN controllers (32 message buffers each), 11 LIN-USART channels with sync-break detection and internal baud rate generators, four I²C interfaces (400 kbps), and a DMA controller with five simultaneous channels supporting 8/16/32-bit transfers and full 32-bit addressing.

FAQ

What is the maximum operating frequency of the MB91F467TAPMC-GSK5E2 core?

The FR60 CPU core operates at a maximum frequency of 100 MHz (CLKB). This is achieved using the on-chip PLL with 4 MHz main oscillator input multiplied by ×25. The 100 MHz clock drives the core while peripheral clocks (CLKP, CLKCAN) run at derived frequencies-50 MHz and 50 MHz respectively-to meet timing requirements of CAN and DMA subsystems.

Does MB91F467TAPMC-GSK5E2 support CAN FD or only classical CAN?

MB91F467TAPMC-GSK5E2 implements C-CAN controllers compliant with ISO 11898-1:2003 (Classical CAN only). It does not support CAN FD features such as flexible data-rate, extended data length, or CRC enhancements. Its two C-CAN modules support up to 1 Mbps classical CAN with 32 message buffers each, suitable for body and chassis networks but not high-bandwidth ADAS domains.

How many I/O pins are available for general-purpose use?

MB91F467TAPMC-GSK5E2 provides up to 109 general-purpose I/O ports, though the actual number depends on pin multiplexing. In QFP-144 package, 102 usable I/O pins are accessible after accounting for power, clock, reset, and mode pins. Port functions include GPIO, peripheral alternate functions (e.g., PPG, ICU, OCU), and analog inputs shared with ADC channels.

Is the on-chip Flash memory protected against unauthorized read/write access?

Yes, MB91F467TAPMC-GSK5E2 includes Flash protection logic that disables external readout and programming via debug interfaces when enabled. Protection is configured through dedicated Flash security registers and persists across power cycles. Once activated, only a full chip erase (requiring specific unlock sequence) can disable protection-meeting basic anti-tampering requirements for automotive ECUs.
