Infineon Technologies MB96F326RSBPMC-GSE2

Overview

MB96F326RSBPMC-GSE2 from Infineon Technologies (formerly Cypress) is a 16-bit F2MC-16FX microcontroller with dual-clock capability, integrated CAN 2.0A/B controller (2 channels), 288 KB Flash, 12 KB RAM, and 18-channel 10-bit SAR ADC. It operates at up to 56 MHz CPU frequency via on-chip PLL (×1–×25), achieves 17.8 ns instruction cycle time, and supports automotive-grade low-voltage reset and clock modulation for EMI reduction. Used in vehicle body control modules requiring real-time CAN communication and mixed-signal processing.

For engineers reviewing the MB96F326RSBPMC-GSE2 datasheet, MB96F326RSBPMC-GSE2 pinout, MB96F326RSBPMC-GSE2 application, or MB96F326RSBPMC-GSE2 equivalent, key selection criteria include dual-clock domain support (main/sub oscillator + RC), 2-channel ISO16845-certified CAN, 18-channel ADC with external trigger capability, and Flash security features including sector protection and 10,000 erase cycles.

Technical Context

The MB96F326RSBPMC-GSE2 implements the F2MC-16FX CPU core with 23 addressing modes, barrel shift, and signed multiply/divide instructions - enabling deterministic control-loop execution in automotive ECUs. Its clock tree allows independent configuration of CPU (up to 56 MHz) and peripheral domains using main oscillator (3–16 MHz), sub-oscillator (32 kHz–100 kHz), or internal 100 kHz/2 MHz RC source.

Peripheral integration includes two ISO16845-certified CAN controllers supporting bit rates up to 1 Mbit/s, 32 message objects with individual identifier masks, and programmable FIFO/loop-back modes. The 10-bit SAR ADC supports single/continuous conversion triggered by software, reload timer, or external event - critical for sensor signal acquisition in body electronics.

FAQ

What is the maximum operating frequency of the MB96F326RSBPMC-GSE2 CPU core?

The CPU core runs at up to 56 MHz using the on-chip PLL multiplier (×1–×25) driven by a 4 MHz external resonator. This yields a minimum instruction cycle time of 17.8 ns. The PLL supports dynamic reconfiguration, and the CPU clock domain is independently selectable from peripheral clocks.

Does MB96F326RSBPMC-GSE2 support CAN FD or only classical CAN?

MB96F326RSBPMC-GSE2 supports only Classical CAN (ISO 11898-1:2003), compliant with CAN protocol version 2.0 Part A and B. It does not implement CAN FD features such as flexible data-rate, extended data length, or CRC enhancements. Bit rates are limited to 1 Mbit/s maximum.

How many ADC channels can be simultaneously sampled with hardware triggering?

The 18-channel 10-bit SAR ADC supports simultaneous sampling only in single-channel mode with external trigger (e.g., reload timer overflow or GPIO edge). It lacks hardware-synchronized multi-channel sampling; sequential conversion across all 18 channels takes ~1.8 µs per channel in continuous mode.

Is the internal RC oscillator calibrated at factory, and can it be adjusted in-system?

Yes - the internal 100 kHz/2 MHz RC oscillator is factory-trimmed for ±2% accuracy. System-level calibration is supported via the Real Time Clock's clock correction register, allowing software adjustment of sub-oscillator or RC oscillator deviation using measured reference periods.
