Infineon Technologies CY96F386RSCPMC-GS-UJE2

Overview

CY96F386RSCPMC-GS-UJE2 from Cypress Semiconductor is a 16-bit F2MC-16FX microcontroller featuring 416 KB on-chip Flash, 16 KB RAM, dual CAN 2.0A/B interfaces, 16-channel 10-bit SAR ADC, and integrated stepper motor controller with six channels. It operates up to 56 MHz via internal PLL (17.8 ns instruction cycle), supports dual clock domains (main/sub/RC), and targets automotive body control, industrial motion systems, and smart appliance HMI with LCD driver (4 COM × 72 SEG).

For engineers reviewing the CY96F386RSCPMC-GS-UJE2 datasheet, CY96F386RSCPMC-GS-UJE2 pinout, CY96F386RSCPMC-GS-UJE2 application, or CY96F386RSCPMC-GS-UJE2 equivalent, key selection criteria include dual CAN channel support, Flash memory size (416 KB), 120-pin LQFP package with dedicated stepper motor PWM outputs, and availability of two independent A/D reference voltage inputs (AVRH/AVRH2).

Technical Context

The CY96F386RSCPMC-GS-UJE2 implements the F2MC-16FX CPU core with 23 addressing modes, barrel shift, signed multiply/divide, and an 8-byte instruction queue. Its clock tree enables independent frequency scaling for CPU (up to 56 MHz) and peripherals using main oscillator (3–16 MHz), subclock (32–100 kHz), or internal RC (100 kHz/2 MHz).

It integrates five CAN channels (two active in this variant), six stepper motor controller channels with synchronized 8/10-bit PWMs, and dual alarm comparators. The device uses a 0.18 μm CMOS process, includes an on-chip voltage regulator for EMI reduction, and supports 13 low-power operating modes including Stop and Timer modes.

FAQ

What clock sources does CY96F386RSCPMC-GS-UJE2 support?

The device supports three independent clock domains: main oscillator (3–16 MHz quartz/ceramic), subclock (32–100 kHz quartz), and internal RC oscillator (100 kHz/2 MHz). The PLL multiplies the main clock up to 56 MHz for CPU operation, while peripherals can run from any domain via flexible clock tree routing - enabling simultaneous high-speed computation and low-power RTC operation.

Does CY96F386RSCPMC-GS-UJE2 support LIN communication?

Yes - it includes five full-duplex USART channels (SCI/LIN capable), with dedicated LIN master/slave functionality on USART0–USART2. Each supports automatic LIN header detection, checksum generation, and configurable baud rates via reload timers, meeting LIN 2.2A compliance for automotive sub-networks.

How is Flash security implemented on this MCU?

Flash security uses a dedicated lock-bit mechanism that prevents external read-out of program memory via serial programming interface. Once enabled, the Flash content cannot be accessed externally; security status is verified during reset. Additionally, sector protection allows selective write/erase locking per 4 KB Flash block - critical for protecting bootloader or calibration data.

Can the LCD controller drive graphic displays?

No - the integrated LCD controller supports only static or multiplexed segment-based displays (4 COM × 72 SEG), not pixel-addressable graphic LCDs. It provides direct drive for alphanumeric panels, bar graphs, and custom symbols via programmable segment mapping. For graphic displays, external controllers or SPI-connected modules are required.
