Infineon Technologies MB96F346ASBPMC-GSE2

Overview

MB96F346ASBPMC-GSE2 from Infineon Technologies (formerly Cypress) is a 16-bit F2MC-16FX microcontroller with dual-clock architecture, 416 KB Flash (Flash A), 16 KB RAM, 2 CAN channels, 24-channel 10-bit SAR ADC, and 7 USARTs. It operates at up to 56 MHz CPU frequency (17.8 ns instruction cycle) using an on-chip PLL driven by a 4 MHz external resonator, targeting automotive body control and industrial real-time embedded systems.

For engineers reviewing the MB96F346ASBPMC-GSE2 datasheet, MB96F346ASBPMC-GSE2 pinout, MB96F346ASBPMC-GSE2 application, or MB96F346ASBPMC-GSE2 equivalent, key selection criteria include dual-clock domain support (main/sub), ISO16845-certified CAN 2.0A/B compliance, flash security features, programmable pulse generator for motor timing, and low-voltage reset disable capability per ordering suffix "S".

Technical Context

The MB96F346ASBPMC-GSE2 implements the F2MC-16FX CPU core with RISC-like pipelined execution, 23 addressing modes, and hardware multiply/divide. Its clock system integrates a configurable PLL (×1–×25), independent CPU/peripheral clock domains, and three oscillator sources: 3–16 MHz main crystal, 32–100 kHz sub-quartz, and 100 kHz/2 MHz internal RC.

Peripheral integration includes two ISO16845-certified CAN controllers (up to 1 Mbit/s, 32 message objects each), seven full-duplex USARTs with LIN master/slave support, four I²C channels (400 kbps), and a 24-channel 10-bit ADC with dual reference voltage switching. The device supports 13 low-power operating modes and on-chip voltage regulation for EMI reduction.

FAQ

What clock sources does MB96F346ASBPMC-GSE2 support?

The device supports three independent clock sources: a 3–16 MHz external crystal/resonator on X0/X1, a 32–100 kHz sub-quartz on XS/X1S, and an internal 100 kHz/2 MHz RC oscillator. Clock domains for CPU and peripherals are selectable independently, enabling precise timing partitioning for CAN, RTC, and ADC subsystems without software overhead.

Does MB96F346ASBPMC-GSE2 support LIN communication?

Yes - all seven USART channels support LIN 2.x functionality, operating either as master or slave. Each USART includes dedicated baud rate reload timers and synchronous protocol adaptation features, allowing direct implementation of LIN cluster nodes without external transceivers beyond physical layer compliance.

How is flash security implemented on this MCU?

Flash security is enforced via a dedicated Flash Security feature that prevents unauthorized read-out of ROM contents through debug interfaces or serial programming. Memory patching remains functional for authorized firmware updates, and sector protection allows selective locking of critical bootloader or calibration regions without affecting user application space.

What is the role of the alarm comparator in system design?

The dual-channel alarm comparator monitors external analog voltages against programmable thresholds - either derived from internal references or external resistive dividers. It generates maskable interrupts for overvoltage or undervoltage conditions, enabling fail-safe shutdown, brown-out recovery, or supply health logging without CPU polling or ADC resource usage.
