Infineon Technologies CY96F356RWBPMC1-GS-UJE2

Overview

CY96F356RWBPMC1-GS-UJE2 from Infineon Technologies (formerly Cypress) is a 16-bit F2MC-16FX microcontroller with dual CAN 2.0A/B controllers, 288 KB on-chip Flash, 12 KB RAM, and 51 I/O pins in 64-pin LQFP. It operates at up to 56 MHz via internal PLL (17.8 ns instruction cycle), supports 10-bit SAR ADC (15 channels), and integrates RTC, PPG, DMA (16 ch), and LIN/USART/I²C peripherals. Used in automotive body control modules requiring real-time CAN communication and low EMI.

For engineers reviewing the CY96F356RWBPMC1-GS-UJE2 datasheet, CY96F356RWBPMC1-GS-UJE2 pinout, CY96F356RWBPMC1-GS-UJE2 application, or CY96F356RWBPMC1-GS-UJE2 equivalent, key selection criteria include dual-CAN channel count, Flash sector protection, clock modulation for EMI reduction, and dual-clock domain support (main/sub/RC oscillators) for fail-safe timing in ASIL-B–aligned systems.

Technical Context

The CY96F356RWBPMC1-GS-UJE2 implements the F2MC-16FX CPU core with 23 addressing modes, barrel shift, and hardware 16×16 signed multiply/32÷16 divide. Its clock tree enables independent frequency selection for CPU (up to 56 MHz) and peripheral domains using main oscillator (3–16 MHz), subclock (32–100 kHz), or internal RC (100 kHz/2 MHz).

It integrates two ISO16845-certified CAN controllers supporting bit rates up to 1 Mbit/s, 32 message objects each, programmable FIFO mode, loop-back self-test, and disabled automatic retransmission for time-triggered operation. The on-chip voltage regulator reduces internal CPU voltage to minimize power and EMI.

FAQ

What is the maximum allowed external crystal frequency for CY96F356RWBPMC1-GS-UJE2?

The device supports external crystal oscillators from 3 MHz to 16 MHz. When using ceramic resonators, the maximum frequency depends on Q-factor and must be verified per board layout; typical limit is 8 MHz for stable startup and jitter performance. The internal PLL can multiply this input up to 56 MHz for CPU operation.

Does CY96F356RWBPMC1-GS-UJE2 support CAN FD?

No. This device implements two CAN 2.0A/B controllers compliant with ISO 11898-1:2015, supporting bit rates up to 1 Mbit/s and message objects with identifier masking and FIFO mode. It does not support CAN FD features such as flexible data-rate, extended payload, or CRC enhancements.

How is Flash memory protected against unauthorized access?

Flash security is enforced via ROM content protection logic that blocks external read-out attempts through serial programming interface. Additionally, the Memory Patch Function allows controlled runtime updates without exposing original firmware, and sector-level write/erase protection prevents accidental overwrites of critical bootloader or calibration regions.

Can the internal RC oscillator be used as the main system clock source?

Yes-the 100 kHz or 2 MHz internal RC oscillator can serve as the primary clock source for CPU and peripherals. It enables fast wake-up from Stop mode (< 10 µs) and safe boot before crystal stabilization. However, its ±2% accuracy limits use in time-critical functions like CAN bit timing or RTC; external crystals remain required for those roles.
