Infineon Technologies CY96F338RWAPMC-GS-UJE2

Overview

CY96F338RWAPMC-GS-UJE2 from Infineon Technologies (formerly Cypress) is a 16-bit F2MC-16FX microcontroller with dual-clock architecture, 544 KB Flash, 32 KB RAM, 3 CAN channels, 8 USARTs, 40-channel 10-bit SAR ADC, and USB Full-Speed interface. It operates up to 48 MHz (20.8 ns instruction cycle), features on-chip PLL, voltage regulator, clock modulation, and supports automotive-grade I/O with Schmitt-trigger inputs and programmable drive strength.

For engineers reviewing the CY96F338RWAPMC-GS-UJE2 datasheet, CY96F338RWAPMC-GS-UJE2 pinout, CY96F338RWAPMC-GS-UJE2 application, or CY96F338RWAPMC-GS-UJE2 equivalent, key selection criteria include dual-clock domain support (main + sub-oscillator), USB Mini-HOST capability, 3-channel CAN with ISO16845 certification, 20-channel PPG for motor control timing, and Flash security with sector protection - all in a 144-pin LQFP package.

Technical Context

The CY96F338RWAPMC-GS-UJE2 implements the F2MC-16FX CPU core with RISC-like pipelined execution, 23 addressing modes, barrel shift, and signed multiply/divide instructions. 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 (CAN 2.0A/B, 1 Mbit/s, 32 message objects), eight full-duplex USARTs with LIN master/slave support, four I²C interfaces (400 kbps), and a 16-bit programmable pulse generator with duty-cycle and cycle registers. The alarm comparator monitors external voltages with maskable interrupts, and the DMA controller supports 10 channels with flexible resource assignment.

FAQ

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

The CY96F338RWAPMC-GS-UJE2 achieves a maximum CPU frequency of 48 MHz using its internal PLL, resulting in a minimum instruction cycle time of 20.8 ns. This performance is sustained across the full industrial temperature range (−40 °C to +105 °C) under 3.3 V ±10% supply conditions, as verified in AC characteristics Table 82 of Document 002-04586 Rev. *D.

Does this MCU support USB device and host functionality simultaneously?

No - the CY96F338RWAPMC-GS-UJE2 supports USB Full-Speed (12 Mbps) device mode and USB Mini-HOST mode, but not simultaneous dual-role operation. Mini-HOST enables enumeration of USB flash drives or HID devices, while device mode supports CDC/DFU class implementations. Both modes share the same PHY and endpoint resources, requiring software reconfiguration.

How many CAN message objects are supported per channel, and are they hardware-queued?

Each of the three CAN channels supports 32 independent message objects, each with dedicated identifier mask and control registers. Message objects can be configured in FIFO mode by concatenating adjacent objects, enabling automatic sequential reception/transmission without CPU intervention - confirmed in Section 3.3.1 of the datasheet.

Is the sub-oscillator (32.768 kHz) integrated or external, and how is RTC accuracy maintained?

The sub-oscillator is external - the MCU provides X0A/X1A pins for connecting a 32.768 kHz quartz crystal. RTC accuracy is maintained via an on-chip clock calibration feature that adjusts the internal divider based on periodic comparison with the main oscillator, correcting for crystal aging and temperature drift - detailed in Section 3.12.3 of Document 002-04586 Rev. *D.
