Product details
Overview
MB91F575BHSPMC-GSK5E1 from Infineon Technologies (formerly Cypress) is a 32-bit FR81S RISC microcontroller for automotive body control and industrial motor management. It operates at up to 80 MHz, integrates 512 KB + 64 KB program flash, 40 KB main RAM + 8 KB backup RAM, and supports LIN-UART (Rev. 2.1), CAN 2.0B (3 channels), and 40-channel 10-bit ADC with 3 µs conversion time.
For engineers reviewing the MB91F575BHSPMC-GSK5E1 datasheet, MB91F575BHSPMC-GSK5E1 pinout, MB91F575BHSPMC-GSK5E1 application, or MB91F575BHSPMC-GSK5E1 equivalent, key selection criteria include its LQFP-144 package, dual-clock supervision (4 MHz main / 32 kHz sub), hardware FPU (IEEE 754), MPU with eight protection areas, and support for sleep/stop low-power modes in harsh environments.
Technical Context
The MB91F575BHSPMC-GSK5E1 implements the FR81S CPU core-a 5-stage pipelined 32-bit RISC architecture with 16 general-purpose registers, 16-bit fixed-length instructions, and single-cycle execution for basic ops. It includes built-in memory protection (MPU), IEEE 754-compliant FPU, and Harvard architecture enabling concurrent instruction fetch and data access.
Peripheral integration targets automotive real-time control: three C-CAN controllers (up to 1 Mbps), six LIN-UART channels with synch-break detection, 24-channel 16-bit PPG, six 32-bit free-run timers with input capture/output compare, and an LCD controller supporting 4-common × 32-segment duty drive or static 9-segment output.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 32-bit automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7F701023 | 16-bit RXv1 core, 64 MHz max, 256 KB flash, no integrated FPU, single CAN channel | Limited floating-point throughput; insufficient for complex PID+observer motor control | Choose when cost sensitivity outweighs need for FPU and multi-CAN routing |
| SPC560B50 | Power Architecture e200z0 core, 64 MHz, 512 KB flash, 48 KB RAM, 2× CAN, no LIN-UART | Lacks native LIN 2.1 support; requires external LIN transceiver and protocol stack | Prefer when AUTOSAR compliance and ASIL-B certification are mandatory |
Compared with R7F701023 and SPC560B50, the MB91F575BHSPMC-GSK5E1 uniquely combines FPU-accelerated math, triple CAN, six LIN-UART channels, and flexible pin relocation-making it optimal for space-constrained automotive modules requiring mixed-protocol connectivity and real-time motor control.

FAQ
Is MB91F575BHSPMC-GSK5E1 pin-compatible with other CY91F57x devices?
Yes-it shares the LQFP-144 footprint and pin assignment with CY91F575B(S)/C(S) and CY91F575BH(S)/CH(S) variants. Key differences lie in flash/RAM configuration and sub-oscillator presence, but all use identical mechanical and electrical pinouts per the datasheet's "Pin Assignment (LQFP-144)" section.
Does this MCU support AUTOSAR OS or MCAL drivers?
No official AUTOSAR MCAL or OS port is provided by Infineon for the CY91570 series. The device lacks certified ASIL-B runtime protection features and standardized driver abstraction layers required for full AUTOSAR compliance, though bare-metal and RTOS-based implementations (e.g., FreeRTOS) are widely deployed in production.
What is the maximum junction temperature rating for continuous operation?
The MB91F575BHSPMC-GSK5E1 is rated for continuous operation up to +125 °C junction temperature, validated per JEDEC JESD22-A108 and specified in Section 13.1 ("Absolute Maximum Ratings") of the datasheet. Thermal design must maintain θJA ≤ 35 °C/W with proper PCB copper pour and thermal vias under worst-case 80 MHz operation.
Can the built-in WorkFlash be used for EEPROM emulation?
Yes-the 64 KB Data Flash (WorkFlash) supports byte-level erase/write with endurance ≥100,000 cycles and data retention ≥20 years at 85 °C. Cypress-provided firmware libraries (e.g., "WorkFlash Driver") implement wear-leveling and atomic update protocols suitable for parameter storage and calibration data logging.
