Infineon Technologies CY96F386RSBPMC-GS-UJE1

Overview

CY96F386RSBPMC-GS-UJE1 from Cypress Semiconductor is a 16-bit F2MC-16FX microcontroller featuring 416 KB on-chip Flash, 16 KB RAM, dual-clock domain support (main + subclock), CAN 2.0A/B interface, and integrated stepper motor controller with six channels. It operates up to 56 MHz via internal PLL (from 4 MHz resonator), delivers 17.8 ns instruction cycle time, and targets automotive body control, industrial motion systems, and smart appliance HMI.

For engineers reviewing the CY96F386RSBPMC-GS-UJE1 datasheet, CY96F386RSBPMC-GS-UJE1 pinout, CY96F386RSBPMC-GS-UJE1 application, or CY96F386RSBPMC-GS-UJE1 equivalent, key selection criteria include dual-clock reset configuration (suffix "S"), 120-pin LQFP package, 5-channel CAN support, 40-channel ADC capability, and Flash security features for firmware protection in safety-critical embedded deployments.

Technical Context

The CY96F386RSBPMC-GS-UJE1 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 16-bit width. Its clock tree supports independent CPU and peripheral domain sourcing from main oscillator, 32–100 kHz subclock, or 100 kHz/2 MHz RC oscillator.

On-chip peripherals include five CAN controllers (ISO16845 certified, up to 1 Mbit/s), six stepper motor channels with dual 8/10-bit PWM per channel, two sound generators, real-time clock with calibration, and dual alarm comparators with external/internal threshold options-configured via dedicated memory-mapped registers and interrupt vectors.

FAQ

What is the purpose of the "S" suffix in CY96F386RSBPMC-GS-UJE1?

The "S" suffix indicates single-clock domain configuration with persistent low-voltage reset functionality. Unlike "W"-suffixed variants, it lacks subclock oscillator support and uses only the main oscillator for reset and timing-simplifying design for applications where dual-clock wake-up is unnecessary and board space is constrained.

Does CY96F386RSBPMC-GS-UJE1 support LIN communication?

Yes-it integrates full-duplex USARTs with LIN protocol support, configurable as either master or slave device. The SCI/LIN peripheral includes dedicated baud rate reload timers and synchronization options, enabling compliance with LIN 2.2A specifications for automotive sub-networks such as seat control or climate sensors.

How many CAN message objects does each CAN channel support?

Each of the five CAN channels supports 32 independent message objects, each with its own identifier mask and programmable FIFO mode. This allows flexible mailbox allocation for standard/extended ID filtering, priority-based transmission, and time-triggered CAN operation with disabled automatic retransmission.

Is external memory required to use the External Bus Interface?

No-external memory is optional. The EBI provides 24-bit addressing and six chip selects for expansion, but the device operates fully standalone using its 416 KB on-chip Flash and 16 KB RAM. External memory is only needed for applications exceeding internal memory capacity or requiring parallel-access peripherals like FPGA co-processors.
