Infineon Technologies MB91F362GBPFVS-G-N1

Overview

MB91F362GBPFVS-G-N1 from Infineon Technologies (formerly Cypress) is a 32-bit FR50 RISC microcontroller designed for high-performance embedded control in automotive and industrial systems. It operates at up to 64 MHz (15.6 ns instruction cycle), integrates 12 KB D-bus RAM, 4 KB instruction RAM, 512 KB Fast Flash, 3 CAN channels, 16-channel 10-bit ADC, and dual 10-bit DACs. Its QFP208 package supports extensive external bus interfacing (32-bit address/32-bit data) and real-time motor control.

For engineers reviewing the MB91F362GBPFVS-G-N1 datasheet, MB91F362GBPFVS-G-N1 pinout, MB91F362GBPFVS-G-N1 application, or MB91F362GBPFVS-G-N1 equivalent, key selection criteria include CAN channel count, external bus width support, integrated stepper motor control, RTC with subclock calibration, and 64 MHz deterministic real-time execution capability.

Technical Context

The MB91F362GBPFVS-G-N1 implements the FR50 32-bit RISC CPU core with five-stage pipeline, fixed 16-bit instruction encoding, and 16 × 32-bit general-purpose registers. It delivers single-cycle instruction execution and 6-cycle interrupt latency, enabling hard real-time response in safety-critical control loops.

Its peripheral set includes three independent CAN controllers (ISO 11898-1 compliant), four-channel stepper motor controller with phase/current control logic, and dual 10-bit DACs with independent output buffers - all synchronized to a shared 64 MHz system clock derived from PLL-stabilized crystal input.

Key Specifications

FAQ

What is the maximum operating temperature range for MB91F362GBPFVS-G-N1?

The MB91F362GBPFVS-G-N1 is qualified for operation from −40 °C to +125 °C ambient temperature, meeting AEC-Q100 Grade 2 requirements for automotive under-hood applications. Its thermal design includes dedicated HVDD/HVSS power domains and thermal pad grounding to sustain continuous 64 MHz operation within this range.

Does MB91F362GBPFVS-G-N1 support CAN FD?

No - MB91F362GBPFVS-G-N1 implements classical ISO 11898-1 CAN 2.0B controllers with bit rates up to 1 Mbps. It does not include CAN FD frame formatting, CRC extension, or flexible data-length support. For CAN FD applications, consider Infineon's newer AURIX™ TC3xx series.

How is the 32 kHz subclock calibrated on this device?

The subclock calibration module measures the deviation between the internal 32.768 kHz oscillator and an external 32.768 kHz crystal reference, then adjusts trimming capacitors via firmware-controlled register writes. Calibration occurs during initialization and can be repeated dynamically to maintain ±1 ppm accuracy across temperature and aging.

Can the external bus interface operate in burst mode?

Yes - the external bus interface supports burst transfers via the DMAC with up to eight configurable channels. When configured for burst mode, the bus controller asserts sequential addresses and latches data on consecutive cycles without reasserting chip select or address lines, achieving peak throughput of 256 MB/s with 32-bit data width and zero wait states.
