Infineon Technologies CY91F467CBPMCR-GS-UJE2

Overview

CY91F467CBPMCR-GS-UJE2 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 high-precision timing. It operates at up to 100 MHz core frequency (CLKB), integrates 1088 KB Flash, 32 KB D-RAM, 32 KB ID-RAM, 3 CAN channels (1 Mbps), 5 DMA channels, and a 10-bit 30-channel ADC with 1 μs conversion time.

For engineers reviewing the CY91F467CBPMCR-GS-UJE2 datasheet, CY91F467CBPMCR-GS-UJE2 pinout, CY91F467CBPMCR-GS-UJE2 application, or CY91F467CBPMCR-GS-UJE2 equivalent, key selection criteria include CAN/LIN coexistence, QFP-144 package compatibility, 100 MHz real-time execution, sub-1 μs interrupt latency (6-cycle save), and integrated stepper motor control with 6-channel PWM outputs.

Technical Context

The CY91F467CB uses the FR60 CPU core - a 32-bit load/store RISC architecture with five-stage pipeline, 16-bit fixed-length instructions, and instruction-level multiplier support (signed 32-bit in 5 cycles). It implements Harvard architecture for simultaneous program/data access and full FR-family instruction compatibility.

Its peripheral set includes three C-CAN controllers (32 message buffers each), five LIN-USART channels (with sync-break detection and dedicated baud rate generator), and a 6-channel stepper motor controller delivering two synchronized 8/10-bit PWMs per channel plus four high-current outputs per channel.

FAQ

What is the maximum operating frequency of the FR60 core in CY91F467CBPMCR-GS-UJE2?

The FR60 core operates at a maximum frequency of 100 MHz (CLKB), achieved using the on-chip PLL with 25× multiplication of the 4 MHz main oscillator. This frequency is fully supported across the −40°C to +105°C operating range and enables deterministic execution of real-time control algorithms with cycle-accurate timing.

Does CY91F467CBPMCR-GS-UJE2 support CAN FD or only classical CAN?

CY91F467CBPMCR-GS-UJE2 implements C-CAN controllers compliant with ISO 11898-1:2003 (classical CAN only), supporting bit rates up to 1 Mbps. It does not support CAN FD features such as flexible data-rate, extended data length, or CRC enhancements - confirmed by the device's peripheral specification and register map in Document 002-04609 Rev. *B.

How many general-purpose I/O ports does CY91F467CBPMCR-GS-UJE2 provide?

The device provides up to 104 general-purpose I/O ports, mapped across multiple port groups (P02, P14–P29), with configurable drive strength, pull-up/down, and alternate function assignment. Pin assignment tables in pages 6–8 of the datasheet confirm all 144 pins are assigned, including power, ground, clock, and dedicated peripheral signals - leaving 104 pins available for GPIO use.

Is the internal 1.8 V logic regulator externally accessible or monitored?

Yes - the internal step-down voltage converter generates 1.8 V for core logic and is monitored by the on-chip supply supervisor. The VCC18C pin (pin 25) provides external access to this regulated rail, allowing external decoupling and optional measurement. The low-voltage detection circuit triggers interrupts if VCC18C falls below 1.62 V or rises above 1.98 V, as specified in Section 8.3 of the datasheet.
