Infineon Technologies MB96F386RSBPMC-GSE2

Overview

MB96F386RSBPMC-GSE2 from Cypress Semiconductor is a 16-bit F2MC-16FX microcontroller with 416 KB on-chip Flash, 16 KB RAM, 5 CAN channels, and 120-pin LQFP package. It features an internal PLL enabling 56 MHz CPU operation (17.8 ns instruction cycle), dual clock domains, and integrated stepper motor controller for motion control systems.

For engineers reviewing the MB96F386RSBPMC-GSE2 datasheet, MB96F386RSBPMC-GSE2 pinout, MB96F386RSBPMC-GSE2 application, or MB96F386RSBPMC-GSE2 equivalent, key selection criteria include CAN 2.0A/B compliance, ISO16845 certification, 32-message-object FIFO, dual-clock domain flexibility, and Flash sector protection for automotive and industrial firmware integrity.

Technical Context

The MB96F386RSBPMC-GSE2 implements Cypress's F2MC-16FX core with instruction pipeline for RISC-like throughput and backward compatibility with 16LX software. Its clock tree supports independent CPU and peripheral domain sourcing from main oscillator (3–16 MHz), subclock (32–100 kHz), or internal RC (100 kHz/2 MHz), enabling low-power timer modes and fast wake-up.

Hardware peripherals include five ISO16845-certified CAN controllers (each with 32 message objects and programmable FIFO), four 16-bit reload timers, twelve 16-bit input capture units, eight 16-bit programmable pulse generators, and a dedicated stepper motor controller with dual 8/10-bit PWMs per channel and high-current drivers.

Key Specifications

Pinout & Package

MB96F386RSBPMC-GSE2 is housed in a 120-pin plastic LQFP (LQM120) package with 0.4 mm lead pitch and exposed thermal pad. Pin functions are defined across six I/O ports (P0–P5), dual clock inputs (X0/X1), CANH/CANL differential pairs for all five CAN channels, dedicated stepper motor outputs (PWM1M0–PWM1P4, PWM2M0–PWM2P4), and dual VCC/VSS power domains (DVCC/DVSS, AVCC/AVSS).

FAQ

What is the maximum operating frequency of the MB96F386RSBPMC-GSE2 CPU?

The MB96F386RSBPMC-GSE2 CPU achieves a maximum operating frequency of 56 MHz using its on-chip PLL clock multiplier, which can scale an external 4 MHz resonator by up to 25×. This yields a minimum instruction cycle time of 17.8 ns, confirmed in the official datasheet (Document Number: 002-04582 Rev. *C, Page 2).

Does MB96F386RSBPMC-GSE2 support ISO16845-certified CAN communication?

Yes - all five CAN controllers on the MB96F386RSBPMC-GSE2 are ISO16845 certified, as explicitly stated in the datasheet (Page 2). This certification validates conformance to physical layer timing, error handling, and bus arbitration behavior required for automotive CAN networks.

What package type and pin count does MB96F386RSBPMC-GSE2 use?

The MB96F386RSBPMC-GSE2 uses a 120-pin plastic LQFP package designated LQM120, with 0.4 mm lead pitch and RoHS compliance. Pin assignment and mechanical dimensions are documented in Section 3 (Page 8) and Package Dimension section (Page 112) of the datasheet.

Can MB96F386RSBPMC-GSE2 operate with dual clock domains?

Yes - the device supports three independent clock sources (main oscillator, subclock, and internal RC oscillator) and allows CPU and two peripheral clock domains to be assigned separately. This capability is detailed in the "System Clock" feature list (Page 2) and enables simultaneous RTC, CAN, and motor control operations without clock contention.
