Infineon Technologies CY96F388HWBPMC-GS-UJE2

Overview

CY96F388HWBPMC-GS-UJE2 from Cypress Semiconductor is a 16-bit F2MC-16FX microcontroller featuring 832 KB Flash (544 KB + 288 KB dual-bank), 32 KB RAM, dual-clock domain support (main/sub), and integrated CAN 2.0A/B interface with ISO16845 certification. It delivers 56 MHz CPU operation via on-chip PLL (17.8 ns instruction cycle), supports 5 CAN channels, 40-channel 10-bit SAR ADC, LCD controller (4 COM × 72 SEG), and stepper motor control with six high-current PWM outputs - deployed in automotive body control modules requiring deterministic real-time communication and mixed-signal actuation.

For engineers reviewing the CY96F388HWBPMC-GS-UJE2 datasheet, CY96F388HWBPMC-GS-UJE2 pinout, CY96F388HWBPMC-GS-UJE2 application, or CY96F388HWBPMC-GS-UJE2 equivalent, key selection criteria include dual-clock reset configuration (suffix "W"), LQFP-120 package compatibility, Flash memory partitioning for OTA updates, CAN FD readiness via software-defined timing, and peripheral clock domain independence for low-power subsystem operation.

Technical Context

The CY96F388HWBPMC-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 separates CPU (PLL-driven up to 56 MHz) and peripheral domains (subclock, RC, or main oscillator selectable per domain), supporting concurrent high-speed computation and low-frequency sensor interface.

Hardware peripherals are tightly coupled to dedicated bus bridges: five CAN controllers share independent message objects (32 total), four 16-bit reload timers feed eight PPG channels, and the 40-channel ADC includes dual reference voltage switching (AVRH/AVRH2). The device supports Flash memory emulation via external RAM and includes Memory Patch functionality for runtime ROM replacement and debug assist.

Manufacturer

Cypress Semiconductor (now part of Infineon Technologies) designs high-performance, mixed-signal embedded solutions for automotive, industrial, and consumer applications, emphasizing reliability, integration, and long-term support.

The CY96F388 belongs to the CY96380 series - a family of 16-bit F2MC-16FX microcontrollers engineered for automotive body electronics and industrial motion control, where deterministic real-time performance, multi-CAN networking, and integrated analog/motor peripherals reduce system complexity.

FAQ

What is the function of the "W" suffix in CY96F388HWBPMC-GS-UJE2?

The "W" suffix indicates dual-clock capability: the device includes both main oscillator (X0/X1) and subsystem oscillator (X0A/X1A) inputs, enabling independent clock domains for CPU and RTC/peripherals. This allows low-power wake-up from subclock while maintaining full-speed CAN operation upon event detection - essential for automotive always-on nodes.

Does CY96F388HWBPMC-GS-UJE2 support CAN FD?

No, the integrated CAN controllers comply strictly with ISO 11898-1:2015 for CAN 2.0A/B (up to 1 Mbit/s). They do not implement CAN FD features such as flexible data-rate, extended data length, or CRC enhancements. CAN FD support would require external protocol translation or migration to a newer Infineon AURIX™ device.

How is Flash memory protected against unauthorized access?

Flash security is enforced via hardware lock bits that disable read-out of user ROM content through serial programming or debug interfaces. Once enabled, the Flash Security feature prevents external extraction of firmware; memory patch operations remain functional for authorized field updates, but only within secured execution context.

Can the LCD controller drive a 4×72 segment display while simultaneously running CAN and ADC tasks?

Yes - the LCD controller operates autonomously using its own clock source (subclock, peripheral clock, or RC oscillator) and internal display memory. It requires no CPU intervention during active display, freeing the 56 MHz CPU for concurrent CAN message handling, 40-channel ADC sampling, and PPG-based motor control without timing conflict.
