Infineon Technologies CY96F356RSBPMC-GS-UJERE2

Overview

CY96F356RSBPMC-GS-UJERE2 from Infineon Technologies (formerly Cypress) is a 16-bit F2MC-16FX microcontroller with dual CAN 2.0A/B controllers, 288 KB on-chip Flash, 12 KB RAM, and 51 GPIOs in 64-pin LQFP. It delivers up to 56 MHz CPU operation via internal PLL (17.8 ns instruction cycle), supports LIN/USART/I²C peripherals, and integrates 15-channel 10-bit SAR ADC - deployed in automotive body control modules requiring real-time CAN messaging and sensor interfacing.

For engineers reviewing the CY96F356RSBPMC-GS-UJERE2 datasheet, CY96F356RSBPMC-GS-UJERE2 pinout, CY96F356RSBPMC-GS-UJERE2 application, or CY96F356RSBPMC-GS-UJERE2 equivalent, key selection criteria include dual-CAN channel count, Flash sector protection, programmable pulse generator (PPG) channel count (20), RTC calibration capability, and support for ISO16845-certified CAN conformance testing.

Technical Context

The CY96F356RSBPMC-GS-UJERE2 implements the F2MC-16FX CPU core with 23 addressing modes, barrel shift, and hardware-signed multiply/divide (16×16, 32/16). Its clock tree enables independent domain scaling: CPU at up to 56 MHz (PLL ×25 from 4 MHz resonator), peripherals at lower frequencies via programmable prescalers.

Dual CAN interfaces each support 32 message objects with individual identifier masks, FIFO concatenation, loop-back self-test, and Time-Triggered CAN mode with disabled automatic retransmission. The 15-channel 10-bit ADC includes external trigger input (ADTG_R), stop conversion mode, and selectable reference voltage (AVRH).

FAQ

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

The CY96F356RSBPMC-GS-UJERE2 achieves 56 MHz CPU clock using its internal PLL multiplier (up to ×25) driven by a 4 MHz external resonator. This yields a minimum instruction cycle time of 17.8 ns, confirmed in the datasheet's AC Characteristics table (Page 54, Rev. *D). The CPU maintains this performance across the full industrial temperature range (−40°C to +105°C) under 2.7–5.5 V supply.

Does this MCU support LIN communication, and how is it implemented?

Yes - the device integrates four full-duplex USARTs with LIN 2.1 compliance. Each USART can operate as LIN master or slave using dedicated hardware baud rate generation and sync-break detection. LIN functionality is implemented in SCI mode with automatic header checksum calculation and response timing control, eliminating software overhead for standard LIN frame handling.

How many CAN message objects does each controller support, and what filtering options exist?

Each of the two CAN controllers supports 32 independent message objects. Each object has its own 29-bit identifier mask for acceptance filtering, enabling precise message routing without CPU intervention. Filtering is performed in hardware before message storage, and objects can be grouped into programmable FIFOs to reduce interrupt load during burst traffic.

Is external memory expansion supported, and what are the bus interface capabilities?

Yes - the MCU provides a multiplexed 24-bit address / 8- or 16-bit data external bus interface with six chip select signals (CS0_R–CS5_R), wait-state control, and programmable timing. It supports external SRAM, Flash, or peripherals with configurable address decoding and timing parameters, enabling direct connection to common industrial memory devices without glue logic.
