Product details

Overview

CY96F338USAPMC-GS-UJE2 from Infineon Technologies (formerly Cypress) is a 16-bit F2MC-16FX microcontroller with USB Full Speed interface, 3-channel CAN 2.0A/B support (ISO16845 certified), 36-channel 10-bit SAR ADC, and 544KB on-chip flash memory. It operates at up to 48 MHz (20.8 ns instruction cycle), features an on-chip PLL, voltage regulator, and 13 low-power operating modes. Used in automotive body control modules requiring real-time CAN communication, analog sensing, and USB diagnostics.

For engineers reviewing the CY96F338USAPMC-GS-UJE2 datasheet, CY96F338USAPMC-GS-UJE2 pinout, CY96F338USAPMC-GS-UJE2 application, or CY96F338USAPMC-GS-UJE2 equivalent, key selection factors include its dual-clock domain support (main + sub-oscillator), programmable pulse generator (20 channels), 36 ADC inputs with external trigger capability, and USB Mini-HOST functionality for peripheral enumeration.

Technical Context

The CY96F338USAPMC-GS-UJE2 implements the F2MC-16FX CPU core with instruction pipeline and RISC-like performance, backward-compatible with 16LX software. Its clock tree supports independent frequency selection for CPU (up to 48 MHz via PLL) and two peripheral domains using main oscillator, 32–100 kHz sub-oscillator, or 100 kHz/2 MHz internal RC oscillator.

It integrates three CAN controllers (each with 32 message objects, FIFO mode, loop-back test, and Time-Triggered disable), eight USARTs (SCI/LIN master/slave), two I²C interfaces (400 kbps, 8-/10-bit addressing), and a 16-channel DMA controller. The alarm comparator monitors external voltages with user-defined thresholds and maskable interrupts.

Real-Time Clock (RTC)	Independent from CPU clock; supports sub-oscillator calibration and interrupt generation at half-second to daily intervals.

Applications

Automotive Body Control Module

Industrial CAN Gateway

Use Scenario: Centralized control of door locks, lighting, window lifts, and HVAC in modern vehicles.

IC Role / Device Role / Timing Role: Primary MCU executing real-time CAN message filtering, sensor fusion (ADC), and actuator PWM (PPG), synchronized via RTC and sub-oscillator.

Use Value: 3 integrated CAN controllers eliminate external transceivers for multi-bus architectures; USB Mini-HOST enables technician tool connectivity for calibration and diagnostics.

Use Scenario: Protocol translation between CAN FD backbone and legacy CAN 2.0 networks in factory automation systems.

IC Role / Device Role / Timing Role: Dual-clock domain operation allows independent timing for CAN message buffering (sub-clock) and USB host polling (PLL-driven CPU clock).

Use Value: 32-message-object FIFO per CAN channel ensures deterministic latency under burst traffic; DMA-accelerated message transfer reduces CPU load by >70% vs. polling.

Smart Energy Meter Interface

Medical Diagnostic Handheld

Use Scenario: Secure metering data aggregation with tamper detection, PLC/CAN backhaul, and local USB configuration port.

IC Role / Device Role / Timing Role: Alarm comparator monitors supply rail integrity; flash security prevents unauthorized firmware access; USB handles secure parameter updates.

Use Value: Low-voltage reset persistence (US suffix) guarantees safe shutdown during brown-out; 20-year flash retention meets utility-grade meter certification requirements.

Use Scenario: Portable ultrasound or ECG device requiring analog front-end sampling, battery-aware sleep scheduling, and PC-based firmware updates.

IC Role / Device Role / Timing Role: 36-channel ADC acquires multi-sensor biometric data; 13 low-power modes extend battery life; USB Full Speed enables <5 s firmware download.

Use Value: Internal RC oscillator provides fast wake-up (<10 µs) from Stop mode; programmable PPG generates precise timing pulses for transducer excitation sequences.

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; no native USB Mini-HOST; 12-bit ADC; 384KB flash.	Lacks USB peripheral enumeration capability; requires external PHY for host functions.	Select when ARM ecosystem compatibility and RTOS support outweigh USB Mini-HOST requirement.
SPC560P50 (STMicroelectronics)	Power Architecture e200z0 core; 2 CAN FD channels; 12-bit ADC; 512KB flash; no USB.	Supports CAN FD but lacks USB interface and sub-oscillator RTC calibration.	Select for CAN FD upgrade path where USB diagnostics are handled externally via UART-to-USB bridge.

Compared with MB9B500R and SPC560P50, CY96F338USAPMC-GS-UJE2 uniquely combines USB Mini-HOST, 3 CAN 2.0 controllers, and sub-oscillator RTC calibration in a single 144-LQFP package-enabling compact, self-contained diagnostic and gateway designs without external USB or CAN transceiver ICs.

FAQ

What is the maximum operating temperature range for CY96F338USAPMC-GS-UJE2?

The device is rated for ambient operating temperature from −40 °C to +105 °C, qualified per AEC-Q100 Grade 2 standards. This rating applies across all supported supply voltages (2.7 V to 5.5 V) and includes full functionality of USB, CAN, ADC, and flash programming operations within this range.

Does CY96F338USAPMC-GS-UJE2 support JTAG or SWD debugging?

No-it uses Cypress's proprietary JTAG-compatible interface called "ICE" (In-Circuit Emulator) with 5-pin connector (TCK, TMS, TDI, TDO, TRST). Debug access requires Cypress/Infineon-compatible tools such as the MiniProg3 or KitProg2; standard ARM SWD probes are not compatible.

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

Yes-the 100 kHz or 2 MHz internal RC oscillator can serve as the primary clock source for CPU and peripherals. It enables fast wake-up from Stop mode (<10 µs) and safe startup before crystal stabilization, but lacks the accuracy needed for USB or CAN timing; external crystal remains mandatory for those functions.

How many simultaneous CAN message objects can be active across all three CAN channels?

All three CAN controllers support 32 message objects each, for a total of 96 configurable message buffers. Each object has independent identifier masking, direction control (Tx/Rx), and FIFO chaining capability-allowing concurrent handling of standard and extended frames across multiple buses without CPU intervention.
