Infineon Technologies CY96F348RSBPMC-GS-UJE2

Overview

CY96F348RSBPMC-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 CAN 2.0A/B interfaces, 24-channel 10-bit SAR ADC, and integrated voltage regulator. It operates at up to 56 MHz via internal PLL (17.8 ns instruction cycle), supports 13 low-power modes, and targets automotive body control modules requiring ISO16845-certified CAN communication and robust EMI performance.

For engineers reviewing the CY96F348RSBPMC-GS-UJE2 datasheet, CY96F348RSBPMC-GS-UJE2 pinout, CY96F348RSBPMC-GS-UJE2 application, or CY96F348RSBPMC-GS-UJE2 equivalent, key selection criteria include dual-CAN channel count, 24-channel ADC resolution and trigger flexibility, flash memory partitioning (Flash A/B), clock domain independence for peripherals, and automotive-grade low-voltage reset persistence with dual-clock support (suffix "R" = dual clock, low-voltage reset disableable).

Technical Context

The CY96F348RSBPMC-GS-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), dual independent clock domains (CPU + two peripheral domains), and three oscillators: 4 MHz external resonator (PLL input), 32–100 kHz subclock quartz, and 100 kHz/2 MHz internal RC oscillator for fail-safe startup.

Peripheral architecture features two CAN controllers (ISO16845 certified, 1 Mbit/s, 32 message objects each), seven full-duplex USARTs with LIN master/slave capability, four I²C channels (400 kbps), and a flexible timer subsystem including 4 × 16-bit free-running timers, 8 × 16-bit output compare units, 8 × 16-bit input capture units, and 16 × 16-bit programmable pulse generators supporting PWM and one-shot operation.

FAQ

What is the maximum operating temperature range for CY96F348RSBPMC-GS-UJE2?

The CY96F348RSBPMC-GS-UJE2 is rated for industrial temperature range (−40 °C to +85 °C) per datasheet section "Recommended Operating Conditions" (page 58). It meets AEC-Q100 Grade 2 stress test requirements (−40 °C to +105 °C) when qualified per Infineon's automotive release documentation, though the "UJE2" suffix denotes industrial-grade packaging and screening.

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

The CY96F348RSBPMC-GS-UJE2 supports only CAN protocol version 2.0 Part A and B (classical CAN), with bit rates up to 1 Mbit/s. It does not implement CAN FD features such as flexible data-rate, extended data length, or CRC enhancements. Its CAN controllers are ISO16845 certified for classical CAN conformance only.

How is flash memory protected against unauthorized read-out?

Flash security is enforced via a dedicated Flash Security feature that disables external read access to ROM contents when enabled. Once activated, the security bit prevents serial programming interface (SPI) read commands and blocks debug access through JTAG/SWD; protection persists across power cycles and requires full chip erase to reset.

Can the internal RC oscillator be used as the main CPU clock source?

Yes-the 100 kHz or 2 MHz internal RC oscillator can serve as the primary CPU clock source, especially for safe boot or low-power modes. However, its accuracy (±10% typical) limits use in timing-critical applications like CAN bit timing or UART baud rate generation; it is recommended for wake-up, watchdog, or pre-stabilization phases before switching to crystal/PLL.
