Infineon Technologies CY96F346RSBPMC-GS-UJE2

Overview

CY96F346RSBPMC-GS-UJE2 from Infineon Technologies (formerly Cypress) is a 16-bit F2MC-16FX microcontroller with dual-clock architecture, 416 KB Flash (Flash A), 16 KB RAM, integrated dual CAN 2.0A/B controllers, 24-channel 10-bit SAR ADC, and programmable pulse generators. It operates at up to 56 MHz CPU frequency via on-chip PLL, supports LIN/SCI/USART/I²C interfaces, and targets automotive body control modules requiring ISO16845-certified CAN communication and low-voltage reset persistence.

For engineers reviewing the CY96F346RSBPMC-GS-UJE2 datasheet, CY96F346RSBPMC-GS-UJE2 pinout, CY96F346RSBPMC-GS-UJE2 application, or CY96F346RSBPMC-GS-UJE2 equivalent, key selection criteria include dual-CAN channel count, 24-channel ADC resolution and reference switching, Flash sector protection, clock modulation for EMI reduction, and support for dual-clock domain operation with subclock calibration.

Technical Context

The CY96F346RSBPMC-GS-UJE2 implements the F2MC-16FX CPU core with instruction pipeline enabling RISC-like performance at 17.8 ns minimum instruction cycle time. Its clock tree supports independent selection of CPU clock (up to 56 MHz via PLL ×1–×25) and peripheral clocks (main/sub/RC oscillators), including 32–100 kHz quartz subsystem clock and 100 kHz/2 MHz internal RC oscillator for safe startup.

It integrates two ISO16845-certified CAN controllers (32 message objects each, bit rates up to 1 Mbit/s), seven full-duplex USARTs with LIN master/slave capability, two I²C interfaces (400 kbps), and a 24-channel 10-bit SAR ADC with dual independent reference voltage inputs (AVRH/AVRL and AVRH2). The device includes 16-bit reload timers (4 + 1 PPG), free-running timers (2), input capture/output compare units (8 each), and alarm comparators (2).

FAQ

What is the maximum operating frequency of the CY96F346RSBPMC-GS-UJE2 CPU core?

The CY96F346RSBPMC-GS-UJE2 CPU core achieves a maximum operating frequency of 56 MHz using its internal PLL clock multiplier (configured up to ×25 from a 4 MHz external resonator). This yields a minimum instruction cycle time of 17.8 ns, verified in the official datasheet (002-04579 Rev. *C, Section 3.1).

Does this microcontroller support LIN communication, and if so, in which modes?

Yes, the CY96F346RSBPMC-GS-UJE2 supports LIN 2.1 communication through its full-duplex USARTs configured as SCI/LIN peripherals. It operates in both master and slave roles, with baud rate generation controlled by a dedicated reload timer and automatic sync-break detection per LIN specification.

How many CAN message objects does each CAN channel support, and are they independently configurable?

Each of the two CAN controllers supports 32 fully independent message objects. Each object has its own identifier mask, acceptance filter, and configurable FIFO mode (concatenated or non-concatenated), allowing flexible mailbox allocation for standard/extended frames and prioritized transmission scheduling.

Is the Flash memory protected against unauthorized access, and what security mechanisms are implemented?

Yes, the Flash memory includes hardware-based security features: ROM content protection prevents external read-out via JTAG or serial programming interface, and Flash sector protection allows locking individual sectors against accidental erase/write. These functions are enabled via dedicated security bits in the Flash configuration register.
