Infineon Technologies CY96F385RWAPMC-GS-UJE2

Overview

CY96F385RWAPMC-GS-UJE2 from Cypress Semiconductor is a 16-bit F2MC-16FX microcontroller featuring 288 KB Flash, 16 KB RAM, dual-clock domain (main + subclock), CAN 2.0A/B interface, and integrated stepper motor controller with six channels. It operates up to 56 MHz via on-chip PLL (from 4 MHz resonator), delivers 17.8 ns instruction cycle time, and supports automotive-grade low-voltage reset disable (RW suffix) in 120-pin LQFP package.

For engineers reviewing the CY96F385RWAPMC-GS-UJE2 datasheet, CY96F385RWAPMC-GS-UJE2 pinout, CY96F385RWAPMC-GS-UJE2 application, or CY96F385RWAPMC-GS-UJE2 equivalent, key selection criteria include dual-clock configurability, ISO16845-certified CAN timing compliance, 6-channel stepper control with synchronized PWMs, and flash security with sector protection for embedded motor control and body electronics.

Technical Context

The CY96F385RWAPMC-GS-UJE2 implements the F2MC-16FX CPU core with 23 addressing modes, barrel shift, signed multiply/divide instructions, and an 8-byte instruction queue-enabling RISC-like throughput at 56 MHz. Its clock tree allows independent CPU (up to 56 MHz) and peripheral domain (e.g., CAN, ADC, RTC) frequency selection using main oscillator, 32–100 kHz subclock, or 100 kHz/2 MHz internal RC source.

It integrates five CAN channels (ISO16845 certified, up to 1 Mbit/s), 16-channel 10-bit SAR ADC with dual reference voltage support, two alarm comparators, and a dedicated 6-channel stepper motor controller with per-channel 8/10-bit PWMs, internal prescaling, and separate high-current driver power supply-targeting deterministic real-time motion control.

FAQ

What is the maximum operating frequency and corresponding instruction cycle time?

The CY96F385RWAPMC-GS-UJE2 achieves a maximum CPU clock frequency of 56 MHz using its on-chip PLL with a 4 MHz external resonator. At this speed, the minimum instruction cycle time is 17.8 ns, confirmed in the Electrical Characteristics section (Page 77) of Document 002-04582 Rev. *C. This timing is guaranteed across the full industrial temperature range (-40°C to +85°C) under specified VCC conditions.

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

This device supports only Classical CAN per ISO 11898-1:2015 (CAN 2.0A/B), 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. The documentation explicitly states "Supports CAN protocol version 2.0 part A and B" and makes no mention of CAN FD capability.

How many independent stepper motor channels can be controlled simultaneously?

The CY96F385RWAPMC-GS-UJE2 integrates a dedicated 6-channel stepper motor controller, each with two synchronized 8/10-bit PWM outputs (M/P pair), enabling concurrent control of up to six independent stepper motors. This is verified in the Product Lineup table (Page 5) and Block Diagram (Page 7), which list "Stepping Motor Controller: 6 channels" for CY96(F)385 devices.

Is the internal RC oscillator accurate enough for RTC operation?

No-the internal RC oscillator (100 kHz/2 MHz) is intended for fast startup and watchdog operation, not RTC timing. For real-time clock functionality, the device requires connection of a 32.768 kHz quartz crystal to X0A/X1A pins, as indicated by the "RW" suffix (dual-clock support) and confirmed in the Clock Source Selection section (Page 2). The subclock oscillator provides ±20 ppm accuracy over temperature, meeting automotive RTC requirements.
