Infineon Technologies CY96F348RSBPQC-GS-UJE2

Overview

CY96F348RSBPQC-GS-UJE2 from Infineon Technologies (formerly Cypress) is a 16-bit F2MC-16FX microcontroller with dual CAN 2.0A/B interfaces, 576 KB on-chip Flash (544 KB + 32 KB), 24 KB RAM, 24-channel 10-bit SAR ADC, and 100-pin LQFP package. It operates up to 56 MHz via internal PLL (17.8 ns instruction cycle), supports LIN master/slave, I²C, USART, RTC, alarm comparator, and programmable pulse generators. Used in automotive body control modules requiring deterministic real-time CAN communication and mixed-signal monitoring.

For engineers reviewing the CY96F348RSBPQC-GS-UJE2 datasheet, CY96F348RSBPQC-GS-UJE2 pinout, CY96F348RSBPQC-GS-UJE2 application, or CY96F348RSBPQC-GS-UJE2 equivalent, key selection criteria include dual-CAN channel count, Flash memory partitioning (Flash A/B), 24-channel ADC with dual reference voltage switching, 16-bit reload/free-running timers with input capture/output compare, and support for dual-clock domain operation (main + subclock).

Technical Context

The CY96F348RSBPQC-GS-UJE2 implements the F2MC-16FX CPU core with RISC-like pipelined execution, 23 addressing modes, barrel shift, and signed multiply/divide instructions. Its clock system integrates a programmable PLL (×1–×25), 32–100 kHz sub-oscillator, and 100 kHz/2 MHz internal RC oscillator - all independently selectable per CPU and two peripheral clock domains.

Peripheral integration includes two ISO16845-certified CAN controllers (up to 1 Mbit/s, 32 message objects each), seven full-duplex USARTs with LIN capability, two I²C interfaces (400 kbps), and a 24-channel ADC with interrupt-on-conversion, external trigger, and dual independent reference voltage inputs (AVRH/AVRL & AVRH2). The device supports 13 low-power operating modes including Stop, Sleep, and Timer-wakeup states.

FAQ

What is the maximum operating frequency and corresponding instruction cycle time?

The CY96F348RSBPQC-GS-UJE2 achieves a maximum CPU clock of 56 MHz using its internal PLL multiplier (×14 from 4 MHz resonator), delivering a minimum instruction cycle time of 17.8 ns. This timing is confirmed in the AC characteristics section (page 68) of datasheet 002-04579 Rev. *C, under "CPU Clock Frequency" and "Instruction Cycle Time" test conditions.

Does this MCU support flash security and memory patching?

Yes - it includes Flash Security to prevent unauthorized ROM read-out and a Memory Patch Function that allows runtime replacement of ROM code segments. These features are documented in sections 1.3 and 1.4 of the datasheet, enabling secure bootloader implementation and field-debuggable firmware patches without full reflash.

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

Each of the two CAN controllers supports 32 independent message objects, each with its own identifier mask and programmable FIFO mode (concatenated message buffering). Configuration is done via CAN Message Object Registers (CMOR) and is fully software-defined - verified in the CAN chapter (pages 101–107) and block diagram (Figure 1).

What are the supported clock sources for the RTC and how is calibration handled?

The RTC can be clocked from the sub-oscillator (32–100 kHz), main oscillator, or internal RC oscillator. Oscillation deviation correction is implemented via a clock calibration register (CALIB) that adjusts timing by ±127 ppm in 1 ppm steps - detailed in Section 12.3 "Real Time Clock" and electrical characteristics table on page 92 of the datasheet.
