Infineon Technologies MB96F387RSBPMC-GSE2

Overview

MB96F387RSBPMC-GSE2 from Cypress Semiconductor is a 16-bit F2MC-16FX microcontroller featuring 576 KB Flash (544 KB + 32 KB dual-bank), 28 KB RAM, integrated CAN 2.0A/B controller, 16-channel 10-bit SAR ADC, and LCD controller supporting up to 4 COM × 65 SEG. It operates at up to 56 MHz via on-chip PLL (17.8 ns instruction cycle) and targets automotive body control modules requiring real-time CAN communication, sensor interfacing, and segmented display driving.

For engineers reviewing the MB96F387RSBPMC-GSE2 datasheet, MB96F387RSBPMC-GSE2 pinout, MB96F387RSBPMC-GSE2 application, or MB96F387RSBPMC-GSE2 equivalent, key selection criteria include dual-bank Flash for safe firmware updates, ISO16845-certified CAN with 32 message objects, programmable clock domains for peripheral independence, and low-voltage reset with persistent enable (suffix "R" indicates reset cannot be disabled).

Technical Context

The MB96F387RSBPMC-GSE2 implements the F2MC-16FX CPU core with 23 addressing modes, barrel shift, signed multiply/divide instructions, and an 8-byte instruction queue-enabling RISC-like performance while maintaining binary compatibility with legacy 16LX software. Its clock tree supports independent domain selection: CPU from PLL (up to 56 MHz), peripherals from main/sub/RC clocks, and LCD from three configurable sources.

Hardware acceleration includes 20-channel 16-bit PPG for PWM generation, 6-channel reload timers with event counting, and a dedicated DMA controller with 16 channels. The device integrates two alarm comparators, dual CAN interfaces (5 total channels), and a stepper motor controller with four high-current outputs per channel-designed for deterministic timing-critical subsystems in automotive ECUs.

Key Specifications

FAQ

What is the maximum operating frequency of the MB96F387RSBPMC-GSE2 CPU core?

The MB96F387RSBPMC-GSE2 CPU core runs at up to 56 MHz using its internal PLL clock multiplier (x1–x25) driven by a 4 MHz external resonator. This yields a minimum instruction cycle time of 17.8 ns. The PLL must be enabled and configured via the Clock & Mode Controller registers; direct external clock input up to 56 MHz is also supported on devices with fast clock input capability.

Does the MB96F387RSBPMC-GSE2 support in-system programming (ISP) via serial interface?

Yes, the MB96F387RSBPMC-GSE2 supports serial programming through its SCI interface (USART0) using the Serial Programming Communication Interface protocol defined in the datasheet. Programming requires a specific command sequence, valid checksum, and proper entry into boot ROM mode via MD0–MD2 pin configuration. Flash security features can lock ISP access after final programming.

How many CAN message objects does the MB96F387RSBPMC-GSE2 support per channel?

Each of the five CAN channels supports 32 individually configurable message objects. Each object includes dedicated identifier, mask, data length, and control registers. Message objects can be grouped into programmable FIFOs for automatic reception handling, reducing CPU intervention during high-throughput CAN traffic.

Is the LCD controller capable of driving static or multiplexed displays?

The MB96F387RSBPMC-GSE2 LCD controller supports only multiplexed displays-specifically up to 4 commons and 65 segments (4 × 65). It provides internal voltage generation, selectable duty cycles (1/2, 1/3, 1/4), fixed 1/3 bias, and programmable frame period. Static segment driving is not supported; all SEG/COM pins are designed for time-multiplexed waveform output.
