Infineon Technologies CY96F348ASBPMC-GS-UJE2

Overview

CY96F348ASBPMC-GS-UJE2 from Infineon Technologies (formerly Cypress) is a 16-bit F2MC-16FX microcontroller with 576 KB on-chip Flash (544 KB Flash A + 32 KB Flash B), 24 KB RAM, dual-clock domain support, and integrated CAN 2.0A/B controller. It operates at up to 56 MHz via internal PLL (17.8 ns instruction cycle), features 24-channel 10-bit SAR ADC, 2-channel alarm comparator, and 2× CAN interfaces - deployed in automotive body control modules requiring deterministic real-time communication and flash-based firmware updates.

For engineers reviewing the CY96F348ASBPMC-GS-UJE2 datasheet, CY96F348ASBPMC-GS-UJE2 pinout, CY96F348ASBPMC-GS-UJE2 application, or CY96F348ASBPMC-GS-UJE2 equivalent, key selection criteria include dual-clock domain configuration (main/sub oscillator), 2× ISO16845-certified CAN channels with programmable FIFO and loop-back test mode, Flash B for safe firmware swap, and 100-pin LQFP package with multiplexed external bus interface.

Technical Context

The CY96F348ASBPMC-GS-UJE2 implements the F2MC-16FX CPU core with RISC-like pipelined execution, 23 addressing modes, and native 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 - enabling independent clock sourcing for CPU and two peripheral domains.

Peripheral architecture includes 2× CAN controllers (each with 32 message objects, maskable interrupts, and disabled auto-retransmission for time-triggered operation), 7× full-duplex USARTs (SCI/LIN master/slave), 2× I²C interfaces (400 kbps, 7-/10-bit addressing), and a 24-channel 10-bit SAR ADC with dual reference voltage switching and external trigger support.

FAQ

What clock sources does CY96F348ASBPMC-GS-UJE2 support for the CPU and peripherals?

The CY96F348ASBPMC-GS-UJE2 supports three independent clock sources: an external 3–16 MHz crystal/resonator (X0/X1) feeding the PLL for up to 56 MHz CPU operation; a 32–100 kHz sub-oscillator (XS/X1S) for RTC and low-power timers; and a 100 kHz/2 MHz internal RC oscillator for fast wake-up and oscillator-failure detection. The CPU and two peripheral clock domains can be assigned separately.

Does CY96F348ASBPMC-GS-UJE2 support LIN communication, and how is it implemented?

Yes - the device integrates full LIN 2.1 functionality within its 7 USART channels. Each USART can operate as LIN master or slave using dedicated hardware baud rate generation, break detection, sync field handling, and checksum calculation. LIN frames are managed autonomously by the SCI peripheral without CPU intervention during normal operation.

How is Flash memory protected against unauthorized access or corruption?

Flash security is enforced via a dedicated Flash Security feature that disables ROM read-out through external interfaces (including serial programming). Sector protection allows locking individual Flash blocks against erase/write operations. Additionally, low-voltage detection during Flash erase prevents incomplete writes, and a completion flag confirms algorithm execution status before software proceeds.

Can CY96F348ASBPMC-GS-UJE2 operate in a single-supply 3.3 V system without external regulators?

Yes - the device integrates an on-chip voltage regulator that steps down the 3.3 V VCC supply to a lower internal core voltage (typically ~1.8 V), reducing dynamic power and EMI. AVCC and VCC share the same 3.3 V rail, but AVCC requires separate 100 nF decoupling adjacent to the package to ensure 10-bit ADC accuracy and noise immunity.
