Infineon Technologies MB96F338RWAPMC-GSE2

Overview

MB96F338RWAPMC-GSE2 from Infineon (formerly Cypress) is a 16-bit F2MC-16FX microcontroller with dual-clock architecture, 48 MHz CPU frequency (20.8 ns instruction cycle), 288 KB Flash, 24 KB RAM, and integrated CAN 2.0A/B controller supporting 1 Mbit/s bit rate across 3 channels - deployed in automotive body control modules requiring deterministic real-time communication and low-power operation.

For engineers reviewing the MB96F338RWAPMC-GSE2 datasheet, MB96F338RWAPMC-GSE2 pinout, MB96F338RWAPMC-GSE2 application, or MB96F338RWAPMC-GSE2 equivalent, key selection criteria include dual-clock domain support (main + sub-oscillator), on-chip voltage regulator for EMI reduction, 3-channel CAN with ISO16845 certification, 40-channel 10-bit SAR ADC, and 144-pin LQFP package with 122 GPIOs.

Technical Context

The MB96F338RWAPMC-GSE2 implements the F2MC-16FX CPU core with instruction pipeline for RISC-like performance, backward compatibility with 16LX software, and hardware acceleration for signed 16×16 multiply and 32÷16 divide operations. Its clock system integrates a programmable PLL (×1–×25), 32–100 kHz sub-oscillator, and 100 kHz/2 MHz internal RC oscillator - enabling independent clock domain selection for CPU and two peripheral buses.

Peripheral integration includes three CAN controllers (ISO16845 certified, 32 message objects each), eight full-duplex USARTs with LIN master/slave capability, four I²C interfaces (400 kbps), and a 10-bit SAR ADC with external trigger support via reload timer. Power management supports 13 operating modes including Stop mode with wake-up via CAN RX or USART SIN pins.

Key Specifications

Pinout & Package

MB96F338RWAPMC-GSE2 is housed in a 144-pin plastic LQFP (M08) package with exposed thermal pad. Pin functions are organized across six I/O ports (P0–P5), dual clock domains (X0/X1 main oscillator; X0A/X1A sub-oscillator), three CAN transceiver interfaces (CAN0–CAN2), eight USART channels (SIN/SOT/SCK), and dedicated analog inputs (AN0–AN39) routed to the 10-bit ADC.

FAQ

What clock sources does MB96F338RWAPMC-GSE2 support?

The device supports three independent clock sources: a 3–16 MHz external crystal/resonator on X0/X1 (main clock), a 32–100 kHz quartz crystal on X0A/X1A (sub-clock), and an internal 100 kHz/2 MHz RC oscillator. The "W" suffix confirms dual-clock capability, allowing CPU and peripherals to operate from different sources simultaneously - e.g., 48 MHz CPU from PLL-driven main clock while RTC runs from 32.768 kHz sub-clock.

Does MB96F338RWAPMC-GSE2 include hardware security features?

Yes - it integrates Flash Security to prevent unauthorized read-out of program memory, Memory Patch functionality for runtime ROM replacement (used in debug and field updates), and a hardware-based Low Voltage Reset (LVR) circuit that asserts reset when VDD drops below 2.7 V (typical). These features collectively support secure boot, firmware integrity, and reliable operation under supply fluctuations.

How many CAN channels are implemented, and what protocol versions do they support?

MB96F338RWAPMC-GSE2 integrates three fully independent CAN controllers, each compliant with ISO 11898-1:2015 and supporting CAN protocol version 2.0 Part A (standard 11-bit ID) and Part B (extended 29-bit ID). All channels are ISO16845 certified, support bit rates up to 1 Mbit/s, and provide 32 configurable message objects with individual identifier masks and programmable FIFO modes.

Is external RAM required for operation, or is on-chip memory sufficient?

No external RAM is required - the device contains 24 KB of on-chip SRAM mapped into the unified address space, sufficient for real-time control stacks, CAN message buffering, and ADC data acquisition. External bus interface (with 6 chip selects and programmable wait states) is optional and used only when expanding memory or connecting peripherals like displays or Ethernet MACs - not needed for baseline CAN/ADC/PPG operation.
