Product details
Overview
CY96F346RSAPMCR-GS-UJE2 from Infineon Technologies (formerly Cypress) is a 16-bit F2MC-16FX microcontroller with dual-clock domain support, 416 KB Flash (Flash A + Data Flash), 16 KB RAM, integrated dual CAN 2.0B controllers, 24-channel 10-bit SAR ADC, and programmable pulse generators. It operates up to 56 MHz via on-chip PLL from a 4 MHz resonator and supports automotive-grade I/O with Schmitt-trigger inputs, voltage regulation, and clock modulation for EMI reduction. Used in body control modules requiring real-time CAN communication and analog sensor interfacing.
For engineers reviewing the CY96F346RSAPMCR-GS-UJE2 datasheet, CY96F346RSAPMCR-GS-UJE2 pinout, CY96F346RSAPMCR-GS-UJE2 application, or CY96F346RSAPMCR-GS-UJE2 equivalent, key selection criteria include dual CAN channel count, 24-channel ADC resolution and trigger sources, Flash memory partitioning (Flash A vs. Data Flash), dual-clock domain configuration (suffix "W"), and LQFP-100 package thermal performance under 125°C ambient.
Technical Context
The CY96F346RSAPMCR-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), independent main/subclock domains, and a 100 kHz/2 MHz internal RC oscillator for safe startup and oscillator failure detection.
Peripheral integration includes two ISO16845-certified CAN controllers (32 message objects each, FIFO mode, loop-back test), 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/AVRH2). The device supports 13 low-power operating modes and on-chip voltage regulation to reduce EMI and active current.

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 |
|---|---|---|---|
| SPC560P50L5 | 32-bit Power Architecture core, 512 KB Flash, single CAN, no integrated voltage regulator | Requires external LDO; lacks dual-clock domain flexibility and PPG-based PWM resolution | Prefer when migrating to AUTOSAR-compliant toolchains or needing higher integer throughput for complex math. |
| RL78/F13 | 16-bit RL78 core, 256 KB Flash, single CAN, 12-bit ADC (8 channels), no Data Flash | Lower ADC channel count and resolution; no dedicated Data Flash for logging; smaller memory footprint | Prefer for cost-sensitive entry-level BCMs where dual CAN and 24-channel ADC are not required. |
Compared with SPC560P50L5 and RL78/F13, the CY96F346RSAPMCR-GS-UJE2 delivers superior analog integration (24×10-bit ADC + dual reference), deterministic real-time performance (17.8 ns cycle), and functional safety-ready features (ISO16845 CAN, clock fail detection) without external regulators or muxes-reducing BOM count and layout complexity in space-constrained automotive modules.

FAQ
What is the maximum operating temperature and thermal design guidance for CY96F346RSAPMCR-GS-UJE2?
The device is rated for −40°C to +125°C ambient operation. Thermal design requires soldering the exposed thermal pad (EPAD) to a minimum 200 mm² copper pour connected to VSS plane. Junction temperature must remain ≤150°C; derate power consumption above 85°C ambient using the 1.8°C/W θJA value specified in the LQFP-100 package drawing.
Does CY96F346RSAPMCR-GS-UJE2 support CAN FD or only classical CAN 2.0?
This MCU supports only Classical CAN 2.0A/B (ISO 11898-1:2003), with bit rates up to 1 Mbit/s and ISO16845 physical layer conformance testing. It does not implement CAN FD protocol features such as flexible data-rate, extended data length, or CRC enhancements. Use case validation requires CAN 2.0-compliant transceivers like TJA1042T/3.
How is Flash memory organized, and can Data Flash be used for EEPROM emulation?
It contains 416 KB total Flash: 352 KB Flash A (code storage) and 64 KB Data Flash (separate erase/write domain). Data Flash supports byte-aligned writes and sector erase (10,000 cycles), enabling reliable EEPROM emulation for parameter storage, calibration data, or event logs without external serial EEPROM.
Is the internal RC oscillator accurate enough for RTC or LIN communication?
The 100 kHz internal RC oscillator has ±10% initial tolerance and ±20% variation over temperature/voltage-insufficient for LIN baud rate accuracy (<1.5% error) or precise RTC. For LIN, use external crystal or ceramic resonator; for RTC, use the 32.768 kHz subsystem quartz oscillator (X2/X3 pins) with optional calibration via clock correction register.
