Product details
Overview
CY96F348RSAPMCR-GS-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, 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, supports LIN/SCI/USART/I²C, and targets automotive body control and industrial real-time control.
For engineers reviewing the CY96F348RSAPMCR-GS-UJE2 datasheet, CY96F348RSAPMCR-GS-UJE2 pinout, CY96F348RSAPMCR-GS-UJE2 application, or CY96F348RSAPMCR-GS-UJE2 equivalent, key selection criteria include dual-clock support (main + sub-oscillator), 2× ISO16845-certified CAN channels, Flash B for secure boot partitioning, 24-channel ADC with dual reference voltage switching, and low-power operation across 13 configurable modes.
Technical Context
The CY96F348RSAPMCR-GS-UJE2 implements the F2MC-16FX CPU core with RISC-like instruction pipeline, 23 addressing modes, and hardware multiply/divide. Its clock system integrates a programmable PLL (×1–×25), 32–100 kHz subsystem quartz oscillator, and 100 kHz/2 MHz internal RC oscillator - all independently selectable per CPU and two peripheral clock domains.
Peripheral integration includes two CAN controllers (each supporting bit rates up to 1 Mbit/s, 32 message objects, FIFO mode, and loop-back self-test), seven full-duplex USARTs with LIN master/slave capability, four I²C channels (400 kbps), and a 24-channel ADC with interrupt-on-conversion, external trigger, and dual AVRH/AVRL reference voltage inputs.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MB9B500R (Renesas) | ARM Cortex-M3 core, 128 KB Flash, no integrated CAN, requires external CAN controller | Lacks dual CAN and Flash B partitioning; targets cost-sensitive non-automotive industrial use | Select when ARM ecosystem toolchain compatibility outweighs CAN integration and boot security needs |
| S9KEAZ128AMLH (NXP) | ARM Cortex-M0+, 128 KB Flash, single CAN 2.0B, 16-channel ADC, 64-pin LQFP | Lower peripheral count and memory; lacks sub-oscillator RTC and dual-reference ADC | Prefer for space-constrained designs where CAN+ADC+LIN fit within 64-pin footprint and 128 KB Flash suffices |
Compared with MB9B500R and S9KEAZ128AMLH, CY96F348RSAPMCR-GS-UJE2 delivers higher integration (dual CAN, 24-channel ADC, Flash B), deterministic real-time performance via 16FX core, and automotive-grade clock redundancy - making it optimal for safety-critical body electronics requiring functional partitioning and ISO16845 compliance.

FAQ
What is the maximum operating frequency and how is it achieved?
The CY96F348RSAPMCR-GS-UJE2 achieves a maximum CPU frequency of 56 MHz using its on-chip PLL clock multiplier, which can scale an external 4 MHz ceramic resonator by factors from ×1 to ×25. This eliminates need for high-frequency crystals while maintaining low EMI through integrated clock modulation and internal voltage regulation.
Does this MCU support secure firmware updates?
Yes - the device features Flash B (32 KB), a physically separate memory block with independent sector protection and Flash Security lock. This allows secure bootloader storage and authenticated firmware updates without risking corruption of main application code in Flash A.
How many CAN message objects does each controller support?
Each of the two CAN controllers supports up to 32 message objects, each with individually programmable identifier masks and acceptance filtering. Message objects can be concatenated into FIFOs, and interrupts are maskable per object - enabling scalable handling of complex automotive network traffic.
Is the sub-oscillator (32–100 kHz) required for RTC operation?
Yes - the Real Time Clock requires either the 32–100 kHz subsystem quartz oscillator (X0A/X1A pins) or the internal RC oscillator. The part number suffix "W" indicates dual-clock capability (main + sub-oscillator), and CY96F348RSAPMCR-GS-UJE2 includes this feature, enabling accurate timekeeping during deep-sleep modes.
