For engineers reviewing the CY96F355RSBPMC-GS-UJE2 datasheet, CY96F355RSBPMC-GS-UJE2 pinout, CY96F355RSBPMC-GS-UJE2 application, or CY96F355RSBPMC-GS-UJE2 equivalent, key selection criteria include its dual-clock domain support (main/sub/RC oscillators), on-chip voltage regulator for EMI reduction, programmable pulse generator (20 channels), 10-bit SAR ADC with 15 channels, and CAN interface with loop-back and time-triggered disable modes.

Technical Context

The CY96F355RSBPMC-GS-UJE2 implements the F2MC-16FX CPU core with 23 addressing modes, barrel shift, and hardware signed multiply/divide (16×16/32÷16). Its clock tree enables independent frequency selection for CPU (up to 56 MHz via PLL) and peripherals using main oscillator (3–16 MHz), subclock (32–100 kHz), or internal RC (100 kHz/2 MHz).

It integrates a full-featured CAN controller compliant with ISO16845, supporting bit rates up to 1 Mbit/s, 32 configurable message objects with individual identifier masks, FIFO concatenation, and programmable automatic retransmission disable for time-triggered operation. The device also includes a real-time clock with subclock calibration and 16-bit reload/free-running timers with input capture/output compare functions.

FAQ

What is the maximum operating frequency and instruction cycle time of the CY96F355RSBPMC-GS-UJE2?

The CY96F355RSBPMC-GS-UJE2 achieves a maximum CPU frequency of 56 MHz using its on-chip PLL, resulting in a minimum instruction cycle time of 17.8 ns. This performance is attainable with a 4 MHz external resonator and requires proper PCB layout for PLL stability, including decoupling capacitors near VCC/VSS pins and controlled impedance traces for X0/X1.

Does the CY96F355RSBPMC-GS-UJE2 support AEC-Q100 qualification?

While the CY96F355RSBPMC-GS-UJE2 is designed for automotive applications and incorporates features aligned with AEC-Q100 requirements-including wide temperature range operation (–40°C to +125°C), on-chip LVR, and EMI mitigation-the official AEC-Q100 qualification status must be verified per specific date-code lot through Infineon's product change notifications (PCNs) and reliability reports.

How many CAN message objects does the CY96F355RSBPMC-GS-UJE2 support, and what filtering options are available?

The device supports 32 independent CAN message objects, each with its own 29-bit identifier mask register for precise acceptance filtering. Message objects can be grouped into programmable FIFOs, and the controller supports both standard (11-bit) and extended (29-bit) identifiers. Maskable interrupts are generated per object or group, enabling efficient mailbox-style reception without CPU polling.

Can the internal RC oscillator be used as the main system clock source, and what is its accuracy?

Yes, the internal RC oscillator provides 100 kHz and 2 MHz outputs for safe startup and oscillator-failure detection. At 2 MHz, typical accuracy is ±2% over –40°C to +105°C, making it suitable for non-timing-critical functions like watchdog supervision or initial boot sequencing-but not for CAN bit timing or RTC, which require crystal or subclock sources.
