Infineon Technologies CY96F346RSCPMC-GS-UJF4E1

Overview

CY96F346RSCPMC-GS-UJF4E1 from Infineon Technologies (formerly Cypress) is a 16-bit F2MC-16FX microcontroller with dual-clock architecture, 416 KB Flash (Flash A + Data Flash), 16 KB RAM, integrated dual CAN 2.0B controllers, 24-channel 10-bit SAR ADC, and programmable pulse generators. It operates up to 56 MHz via on-chip PLL from a 4 MHz resonator and supports automotive-grade I/O with Schmitt-trigger inputs, voltage regulation, and clock modulation for EMI reduction. Used in body control modules requiring real-time CAN communication and analog sensor interfacing.

For engineers reviewing the CY96F346RSCPMC-GS-UJF4E1 datasheet, CY96F346RSCPMC-GS-UJF4E1 pinout, CY96F346RSCPMC-GS-UJF4E1 application, or CY96F346RSCPMC-GS-UJF4E1 equivalent, key selection criteria include dual-CAN channel count, 24-channel ADC resolution and trigger sources, Flash sector protection, low-voltage reset persistence, and QFP-100 package compatibility with legacy 16LX software migration paths.

Technical Context

The CY96F346RSCPMC-GS-UJF4E1 implements the F2MC-16FX CPU core with instruction pipeline enabling RISC-like performance at up to 56 MHz (17.8 ns instruction cycle), while maintaining full binary compatibility with Cypress 16LX firmware. Its dual-clock domain supports independent CPU and peripheral clocking - main clock (3–16 MHz crystal or 56 MHz external), subclock (32–100 kHz quartz), and internal 100 kHz/2 MHz RC oscillator with oscillator stop detection.

It integrates two ISO16845-certified CAN 2.0A/B controllers (32 message objects each, up to 1 Mbit/s, FIFO mode, loop-back self-test), seven full-duplex USARTs with LIN master/slave support, four I²C channels (400 kbps), and a 24-channel 10-bit SAR ADC with dual reference voltage switching (AVRH/AVRL or AVRH2). The alarm comparator monitors external voltages with interrupt-on-threshold-crossing capability.

FAQ

Is CY96F346RSCPMC-GS-UJF4E1 pin-compatible with earlier CY96346 series devices?

Yes - it shares identical 100-pin LQFP mechanical footprint and electrical pin mapping with CY96346R devices. The "F" suffix denotes Flash-based implementation versus mask ROM, but all I/O, power, clock, and peripheral pin functions remain consistent per datasheet 002-04579 Rev. *C, page 7.

Does this MCU support LIN 2.1 physical layer compliance?

No - it implements LIN 2.0 protocol stack in firmware via its USARTs with dedicated LIN break detection and sync field handling, but lacks integrated LIN PHY. External LIN transceivers (e.g., TLE7259-3GE) must be used for physical layer compliance per ISO 17987-4.

What is the maximum allowed ADC input voltage range?

The absolute maximum analog input voltage is AVCC + 0.3 V, with recommended operating range of 0 V to AVCC. When AVRH = AVCC and AVRL = VSS, full-scale conversion corresponds to 0–AVCC; AVRH2 enables alternate reference routing for ratiometric sensor measurements.

Can the on-chip PLL operate with a 4 MHz ceramic resonator?

Yes - the PLL accepts 4 MHz input from a ceramic resonator and multiplies it up to 56 MHz (×14). Datasheet section "Notes on PLL clock mode operation" confirms stable PLL lock with Q-factor ≥100 resonators; external load capacitors must match resonator specifications.
