Infineon Technologies CY96F348RWCPMC-G-UJE2

Overview

CY96F348RWCPMC-G-UJE2 from Infineon Technologies (formerly Cypress) is a 16-bit F2MC-16FX microcontroller with dual-clock architecture, 576 KB on-chip Flash (544 KB Flash A + 32 KB Flash B), 24 KB RAM, integrated dual CAN 2.0A/B controllers, 24-channel 10-bit SAR ADC, and 2-channel alarm comparator. It operates up to 56 MHz via internal PLL (17.8 ns instruction cycle), supports LIN/SCI/USART/I²C interfaces, and targets automotive body control, industrial PLC I/O modules, and CAN-based gateway applications.

For engineers reviewing the CY96F348RWCPMC-G-UJE2 datasheet, CY96F348RWCPMC-G-UJE2 pinout, CY96F348RWCPMC-G-UJE2 application, or CY96F348RWCPMC-G-UJE2 equivalent, key selection criteria include dual-clock domain support (main + subclock), 2× ISO16845-certified CAN channels, Flash B for secure boot partitioning, 100-pin LQFP package with 82 GPIOs, and low-voltage reset disable capability (suffix "R" + "W").

Technical Context

The CY96F348RWCPMC-G-UJE2 implements the F2MC-16FX CPU core with RISC-like pipelined execution, 23 addressing modes, and hardware multiply/divide. Its clock system integrates a programmable PLL (×1–×25), 32–100 kHz subclock oscillator, and 100 kHz/2 MHz internal RC oscillator-each independently assignable to CPU and two peripheral clock domains.

Peripheral integration includes two CAN controllers (32 message objects each, FIFO mode, loop-back test), seven full-duplex USARTs with LIN master/slave support, four I²C channels (400 kbps), and a 24-channel ADC with dual reference voltage switching (AVRH/AVRL or 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 CY96F348RWCPMC-G-UJE2 achieves a maximum CPU clock of 56 MHz using its internal PLL multiplier (×14 from 4 MHz resonator). At this frequency, the minimum instruction cycle time is 17.8 ns. This timing is guaranteed across the full industrial temperature range (−40°C to +105°C) and 3.3 V ±10% supply, as verified in AC characteristics Table 4-1 of datasheet 002-04579 Rev. *C.

Does this part support CAN FD or only classical CAN 2.0?

CY96F348RWCPMC-G-UJE2 implements two CAN 2.0A/B controllers compliant with ISO 11898-1:2015 and certified to ISO 16845 test suites. It does not support CAN FD frame format, bit rate switching, or extended data length. The controllers operate up to 1 Mbit/s with 32 message objects per channel, FIFO mode, and programmable loop-back for self-test.

How is Flash B used, and what prevents accidental overwrite of the boot loader?

Flash B (32 KB) is physically separate from Flash A and supports independent sector erase, write protection, and memory patch functions. Sector protection bits (set via Flash security command) lock Flash B against unintended programming or read-out. Boot vector mapping is controlled by MD0–MD2 pins at reset, allowing secure boot from Flash B while running application code from Flash A.

Is the subclock oscillator functional with ceramic resonators, or only quartz crystals?

The subclock oscillator (X0A/X1A) is designed exclusively for 32.768 kHz quartz crystals-not ceramic resonators-as specified in Section 5.4 ("Unused sub clock signal") and Electrical Characteristics Table 5-2. Ceramic resonators lack the required Q-factor and frequency stability for reliable RTC operation and low-power wake-up timing accuracy.
