Infineon Technologies CY96F346ASBPQC-G-UJE2

Overview

CY96F346ASBPQC-G-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, two CAN 2.0B interfaces, 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/USART/I²C, and targets automotive body control, industrial PLC I/O modules, and CAN-based gateway nodes.

For engineers reviewing the CY96F346ASBPQC-G-UJE2 datasheet, CY96F346ASBPQC-G-UJE2 pinout, CY96F346ASBPQC-G-UJE2 application, or CY96F346ASBPQC-G-UJE2 equivalent, key selection criteria include dual-clock domain support (main + subclock), 2× ISO16845-certified CAN controllers with 32 message objects each, programmable pulse generator for motor timing, on-chip voltage regulator for EMI reduction, and Flash security with sector protection.

Technical Context

The CY96F346ASBPQC-G-UJE2 implements the F2MC-16FX CPU core with RISC-like pipelined execution, 23 addressing modes, and native 16×16 signed multiply / 32÷16 divide instructions. Its clock tree allows independent frequency selection for CPU (up to 56 MHz) and peripherals using main oscillator, 32–100 kHz subclock, or 100 kHz/2 MHz internal RC source.

Peripheral integration includes two CAN controllers (each with FIFO mode, loop-back test, and time-triggered disable), seven full-duplex USARTs with LIN master/slave capability, 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 modes including Stop and Timer-wakeup modes with oscillator stop detection.

FAQ

What is the maximum operating frequency and how is it achieved?

The CY96F346ASBPQC-G-UJE2 achieves 56 MHz CPU operation using its on-chip PLL with multiplication factors up to ×25, driven by an external 4 MHz ceramic resonator. This yields a 17.8 ns instruction cycle time while maintaining low EMI through integrated clock modulation and voltage regulation-no external clock generator or high-frequency crystal required.

Does this part support LIN communication natively?

Yes. The CY96F346ASBPQC-G-UJE2 integrates LIN functionality directly into seven of its USART channels, supporting both master and slave roles per channel. Each LIN-capable USART includes dedicated baud rate reload timers and sync-break detection circuitry-no external LIN transceiver or software stack overhead is needed for basic frame handling.

How many CAN message objects does each controller support?

Each of the two CAN controllers supports 32 independent message objects, each with configurable identifier, mask, and data length. Message objects can be concatenated into FIFOs for efficient reception, and all support maskable interrupts, automatic retransmission disable (for time-triggered use), and loop-back self-test mode-validated per ISO16845 compliance testing.

Is Flash security implemented in hardware or software?

Flash security is implemented in hardware via dedicated protection logic that prevents unauthorized read-out of ROM contents through JTAG or serial programming interfaces. Security activation permanently disables external access to protected sectors; it is enforced independently of software execution state and survives power cycles-verified in Infineon's flash security documentation for CY96F34x series.
