Infineon Technologies MB96F338USAPMC-GS-N2E2

Overview

MB96F338USAPMC-GS-N2E2 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, internal voltage regulator, and 13 low-power operating modes. Used in automotive body control modules requiring real-time CAN/USB coexistence and analog sensor acquisition.

For engineers reviewing the MB96F338USAPMC-GS-N2E2 datasheet, MB96F338USAPMC-GS-N2E2 pinout, MB96F338USAPMC-GS-N2E2 application, or MB96F338USAPMC-GS-N2E2 equivalent, key selection considerations include its dual-clock domain flexibility, USB Mini-HOST capability, 36-channel ADC with external trigger support, and ISO16845-certified CAN timing compliance for automotive ECU designs.

Technical Context

The device implements the F2MC-16FX CPU core with instruction pipeline and RISC-like performance, maintaining software compatibility with legacy 16LX series while delivering higher throughput and lower power. Its clock architecture supports independent selection of CPU and peripheral clock sources-including main oscillator (3–16 MHz), sub-oscillator (32–100 kHz), and 100 kHz/2 MHz internal RC oscillator-with programmable prescalers and clock modulation for EMI reduction.

Peripheral integration includes three independent CAN controllers with 32 message objects each, eight full-duplex USARTs supporting LIN master/slave operation, four I²C interfaces (400 kbps), and a 16-bit programmable pulse generator with PWM/one-shot modes. The alarm comparator monitors external voltages with configurable thresholds and interrupt masking, and the external bus interface provides 24-bit addressing with six chip selects and wait-state control.

FAQ

Does MB96F338USAPMC-GS-N2E2 support USB device and host modes simultaneously?

No. The device implements USB Full Speed function mode and USB Mini-HOST mode, but they cannot operate concurrently. USB function mode supports device enumeration on a host PC, while Mini-HOST mode enables connection to USB peripherals like flash drives or diagnostic dongles. Mode selection is configured at boot via MD pins and software initialization.

What is the maximum allowed external clock frequency for the main oscillator?

The main oscillator input (X0/X1) accepts frequencies from 3 MHz to 16 MHz when using a quartz crystal. With ceramic resonators, the maximum usable frequency depends on Q-factor and is typically limited to 8 MHz for reliable startup and stability. External clock input (ECCLK) supports up to 48 MHz directly applied to the CLKIN pin.

How many CAN message objects can be configured per channel, and are they shared or independent?

Each of the three CAN channels supports 32 dedicated message objects, with individual identifier masks and FIFO configuration. Message objects are not shared across channels - each channel maintains its own 32-object RAM buffer, enabling independent filtering, transmission prioritization, and interrupt generation per CAN bus.

Is the internal RC oscillator accurate enough for real-time clock (RTC) operation without calibration?

The internal 100 kHz RC oscillator has ±10% initial tolerance and significant temperature/voltage drift, making it unsuitable for standalone RTC use. However, the device includes clock calibration logic that adjusts the RTC divider based on periodic comparisons with the more stable sub-oscillator (32.768 kHz quartz), enabling compensated RTC operation even when the sub-oscillator is unavailable.
