Infineon Technologies CY96F338RSAPMCR-G-UJE2

Overview

CY96F338RSAPMCR-G-UJE2 from Infineon Technologies (formerly Cypress) is a 16-bit F2MC-16FX microcontroller with 544 KB Flash, 32 KB RAM, 3-channel CAN 2.0A/B interface, 40-channel 10-bit SAR ADC, and USB Full-Speed functionality. It operates at up to 48 MHz (20.8 ns instruction cycle), features an on-chip PLL, clock modulation for EMI reduction, and supports automotive-grade low-voltage reset and dual-clock domain operation.

For engineers reviewing the CY96F338RSAPMCR-G-UJE2 datasheet, CY96F338RSAPMCR-G-UJE2 pinout, CY96F338RSAPMCR-G-UJE2 application, or CY96F338RSAPMCR-G-UJE2 equivalent, key selection criteria include its 3 CAN channels with ISO16845 certification, 40 ADC inputs with external reference voltage switching, 144-pin LQFP package with 122 I/O pins (suffix "R" = single-clock, low-voltage-reset-disablable), and USB Mini-HOST support for peripheral enumeration.

Technical Context

The CY96F338RSAPMCR-G-UJE2 implements the proprietary F2MC-16FX CPU core with RISC-like pipelined execution, 23 addressing modes, barrel shift, and hardware-signed multiply/divide. Its clock system integrates a programmable PLL (×1–×25), 32–100 kHz sub-oscillator, and 100 kHz/2 MHz internal RC oscillator - all independently selectable per CPU and two peripheral clock domains.

Peripheral integration includes three independent CAN controllers (each with 32 message objects, FIFO mode, loop-back, and time-triggered disable), eight full-duplex USARTs with LIN master/slave capability, four I²C interfaces (400 kbps), and a 16-bit programmable pulse generator supporting PWM and one-shot modes with prescaler options down to 1/64 of peripheral clock.

FAQ

What is the maximum operating frequency and corresponding instruction cycle time?

The CY96F338RSAPMCR-G-UJE2 achieves a maximum CPU clock of 48 MHz using its internal PLL with a 4 MHz external resonator, delivering a minimum instruction cycle time of 20.8 ns. This performance is sustained across the full operating voltage range (2.7–5.5 V) and ambient temperature range (–40°C to +125°C), verified per Infineon's AC characteristics table (Document 002-04586 Rev. *D, Page 82).

Does this part support USB device and host functionality simultaneously?

No - the CY96F338RSAPMCR-G-UJE2 supports USB Full-Speed device mode and USB Mini-HOST mode, but not simultaneous dual-role operation. The USB controller uses a single PHY and endpoint manager; configuration is fixed at boot via internal registers and cannot be dynamically switched during runtime without full reinitialization.

How many CAN message objects are supported, and are they shared across channels?

Each of the three CAN controllers supports 32 dedicated message objects, totaling 96 message objects. Objects are not shared - each channel has independent acceptance filtering, transmit/receive buffers, and interrupt vectors. Message object allocation is fully configurable per channel via CAN Message Object RAM (CMOR) registers, enabling flexible mailbox or FIFO usage per interface.

Is the Flash memory capable of in-application programming (IAP)?

Yes - the 544 KB Flash supports in-application programming via the embedded Flash algorithm. Code executing from RAM can issue Write/Erase/Suspend/Resume commands to any unprotected sector. Completion is signaled by a status flag (FSTAT register), and sector protection bits prevent accidental overwrite of bootloader or critical firmware sections.
