Infineon Technologies CY96F348RSBPQCR-GSUJERE2

Overview

CY96F348RSBPQCR-GSUJERE2 from Infineon Technologies (formerly Cypress) is a 16-bit F2MC-16FX microcontroller with dual CAN 2.0A/B interfaces, 576 KB on-chip Flash (544 KB Flash A + 32 KB Flash B), 24 KB RAM, and 100-pin LQFP package. It operates at up to 56 MHz CPU frequency (17.8 ns instruction cycle), supports 24-channel 10-bit SAR ADC, dual I²C, seven USARTs (with LIN master/slave), and real-time clock with subclock calibration - deployed in automotive body control modules requiring deterministic CAN messaging and mixed-signal monitoring.

For engineers reviewing the CY96F348RSBPQCR-GSUJERE2 datasheet, CY96F348RSBPQCR-GSUJERE2 pinout, CY96F348RSBPQCR-GSUJERE2 application, or CY96F348RSBPQCR-GSUJERE2 equivalent, key selection criteria include dual-CAN channel count, Flash B partitioning for safe firmware updates, 24-channel ADC input routing, LQFP-100 thermal performance, and compatibility with legacy 16LX software migration paths.

Technical Context

The CY96F348RSBPQCR-GSUJERE2 implements the F2MC-16FX CPU core with instruction pipeline for RISC-like throughput, executing instructions in 17.8 ns at 56 MHz using an internal PLL multiplier (x1–x25) driven by a 4 MHz external resonator. Its clock tree enables independent domain configuration: CPU, peripheral bus 1, and peripheral bus 2 each select distinct clock sources (main oscillator, subclock, or RC oscillator).

It integrates two ISO16845-certified CAN controllers supporting bit rates up to 1 Mbit/s, 32 message objects per channel with individual identifier masks, programmable FIFO concatenation, and loop-back mode for self-test. The 24-channel 10-bit SAR ADC includes dual reference voltage inputs (AVRH/AVRL and AVRH2), conversion trigger options (software, reload timer, external), and interrupt generation per channel.

FAQ

What is the maximum operating temperature and qualification grade for CY96F348RSBPQCR-GSUJERE2?

The CY96F348RSBPQCR-GSUJERE2 is qualified to AEC-Q100 Grade 2 (−40°C to +105°C ambient), with junction temperature rated up to +125°C. Its 100-pin LQFP package features internal thermal pad design and copper leadframe construction to sustain continuous operation at full 56 MHz CPU frequency under industrial and automotive under-hood conditions.

Does this MCU support LIN 2.2 protocol natively, and how is slave wakeup implemented?

Yes, the CY96F348RSBPQCR-GSUJERE2 supports LIN 2.2 as both master and slave via its seven USART channels. Slave wakeup is implemented through dedicated SINx pins that detect dominant pulses on the LIN bus and generate interrupts even in Stop mode, enabling sub-100 µs response without CPU polling or external circuitry.

How does the Flash B partition differ from Flash A in terms of erase granularity and security?

Flash B (32 KB) supports sector-erase only - identical granularity to Flash A - but is configured as a dedicated, write-protected update region. Its security lock bits prevent read-out or accidental overwrite during normal Flash A execution, enabling certified A/B firmware rollbacks and secure OTA updates compliant with ISO/SAE 21434 cybersecurity requirements.

Can the 24-channel ADC operate simultaneously with the alarm comparator and real-time clock active?

Yes. The ADC, alarm comparator, and RTC operate independently on separate clock domains (CLKP1, ALARM clock, subclock). All three functions remain fully operational during Stop mode with only the 100 kHz RC oscillator active, allowing continuous voltage monitoring, time-stamped event capture, and periodic sensor sampling without CPU intervention.
