Overview

MB96F346RSBPQC-GSE2 from Infineon Technologies (formerly Cypress) is a 16-bit F2MC-16FX microcontroller with dual-clock architecture, 416 KB Flash (Flash A), 16 KB RAM, two CAN 2.0B interfaces, 24-channel 10-bit SAR ADC, and 100-pin LQFP package. It operates up to 56 MHz via on-chip PLL driven by a 4 MHz resonator, delivers 17.8 ns instruction cycle time, and supports automotive-grade low-power operation with 13 configurable power modes.

For engineers reviewing the MB96F346RSBPQC-GSE2 datasheet, MB96F346RSBPQC-GSE2 pinout, MB96F346RSBPQC-GSE2 application, or MB96F346RSBPQC-GSE2 equivalent, key selection criteria include dual-clock domain support (main/sub), CAN protocol compliance (ISO16845), Flash sector protection, programmable pulse generator (PPG) count (16 channels), and alarm comparator availability (2 channels).

Technical Context

The MB96F346RSBPQC-GSE2 implements the F2MC-16FX CPU core with RISC-like pipelined execution, 23 addressing modes, barrel shift, and native 16×16 signed multiply/32÷16 divide instructions. Its clock tree allows independent frequency selection for CPU (up to 56 MHz) and peripheral domains using main oscillator, sub-oscillator (32–100 kHz), or internal 100 kHz/2 MHz RC source.

Peripheral integration includes two ISO16845-certified CAN controllers (32 message objects each, FIFO mode, loop-back test), seven full-duplex USARTs with LIN master/slave capability, four I²C channels (400 kbps), and a 24-input ADC with dual reference voltage switching (AVRH/AVRL or AVRH2). The device supports external bus interface with 6 chip selects and multiplexed address/data lines.

FAQ

What is the maximum operating frequency of the MB96F346RSBPQC-GSE2 CPU core?

The MB96F346RSBPQC-GSE2 CPU core runs at up to 56 MHz using its integrated PLL clock multiplier. This frequency is achieved with an external 4 MHz ceramic resonator input, resulting in a minimum instruction cycle time of 17.8 ns. The PLL supports multiplication factors from x1 to x25, and the device also accepts direct external clock inputs up to 56 MHz on models with fast clock input capability.

Does MB96F346RSBPQC-GSE2 support LIN communication, and how is it implemented?

Yes, MB96F346RSBPQC-GSE2 supports LIN 2.1 communication through its full-duplex USART peripherals. Each USART can be configured as LIN master or slave using dedicated baud rate reload timers and synchronous serial options. LIN frame generation, checksum calculation, and header/response timing comply with ISO 17987-4, and the device supports automatic wake-up detection on LIN bus activity.

How many CAN message objects does MB96F346RSBPQC-GSE2 support, and what configuration options exist?

The MB96F346RSBPQC-GSE2 integrates two independent CAN 2.0B controllers, each supporting 32 message objects. Each object has individually programmable identifier masks, acceptance filtering, and configurable FIFO mode (concatenated message storage). Message transmission supports automatic retransmission, loop-back self-test, and disabled retransmission for time-triggered CAN operation.

Is the MB96F346RSBPQC-GSE2 qualified for automotive applications, and what reliability features does it include?

MB96F346RSBPQC-GSE2 meets AEC-Q100 Grade 2 requirements (−40 °C to +105 °C ambient) and includes automotive-specific features: dual-clock domain operation for fail-safe RTC, low-voltage reset with persistent or disableable behavior (suffix "R"), on-chip voltage regulator for EMI reduction, clock modulation circuit, and Flash security with ROM protection. It also supports oscillator stop detection and watchdog timer with independent RC clock source.
