Infineon Technologies CY96F347RSAPQCR-GSUJERE2

Overview

CY96F347RSAPQCR-GSUJERE2 from Infineon Technologies (formerly Cypress) is a 16-bit F2MC-16FX microcontroller with dual-clock architecture, 544 KB on-chip Flash memory, 24 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 internal PLL (17.8 ns instruction cycle), supports LIN master/slave, I²C, USART, and real-time clock - deployed in automotive body control modules requiring deterministic CAN timing and low EMI.

For engineers reviewing the CY96F347RSAPQCR-GSUJERE2 datasheet, CY96F347RSAPQCR-GSUJERE2 pinout, CY96F347RSAPQCR-GSUJERE2 application, or CY96F347RSAPQCR-GSUJERE2 equivalent, key selection criteria include dual-clock domain support (main + sub-oscillator), 2× ISO16845-certified CAN controllers, Flash security features, programmable pulse generators for motor control, and automotive-grade I/O voltage tolerance (5 V tolerant inputs).

Technical Context

The CY96F347RSAPQCR-GSUJERE2 implements the F2MC-16FX CPU core with RISC-like pipelined execution, 23 addressing modes, and native signed multiply/divide instructions. Its clock system integrates a programmable PLL (×1–×25), 32–100 kHz sub-oscillator, and 100 kHz/2 MHz internal RC oscillator - enabling independent clock domains for CPU and peripherals.

Peripheral integration includes two CAN 2.0B controllers (32 message objects each, loop-back/self-test mode), seven full-duplex USARTs with LIN support, two I²C masters/slaves (400 kbps), and a 24-channel ADC with dual reference voltage switching (AVRH/AVRL or AVRH2). The device supports 13 low-power operating modes and on-chip voltage regulation for EMI reduction.

FAQ

What is the maximum operating temperature range for CY96F347RSAPQCR-GSUJERE2?

The CY96F347RSAPQCR-GSUJERE2 is qualified for operation from –40°C to +125°C ambient temperature, meeting AEC-Q100 Grade 2 requirements. This rating applies to all core logic, Flash memory, ADC, CAN, and I/O circuits when powered within specified VCC and AVCC ranges per datasheet Section 5.6.

Does this MCU support CAN FD or only classical CAN 2.0?

The CY96F347RSAPQCR-GSUJERE2 supports only CAN 2.0A/B protocol (ISO 11898-1:2003), with bit rates up to 1 Mbit/s and ISO16845 physical layer certification. It does not implement CAN FD features such as flexible data-rate, extended data length, or CRC enhancements.

How is Flash security implemented to prevent unauthorized code extraction?

Flash security uses a write-protected lock bit that disables external read access to user Flash and Boot ROM. Once enabled, the protection persists through power cycles and resets. Debug access via JTAG/SWD is also disabled unless unlocked via specific secure sequence - verified in datasheet Section 21 "Flash Security Feature".

Can the internal RC oscillator be used as the main CPU clock source in production systems?

Yes - the 100 kHz or 2 MHz internal RC oscillator can serve as the primary CPU clock source, enabling fast wake-up from Stop mode (< 10 µs) and safe operation during crystal startup failure. Accuracy is ±1% over temperature and voltage, sufficient for non-timing-critical control loops but not for CAN bit timing without calibration.
