Product details
Overview
MB91F469GAPB-GS-K6 from Infineon Technologies (formerly Cypress) is a 32-bit RISC microcontroller based on the FR60 CPU core, designed for real-time embedded control in automotive and industrial systems. It integrates 6-channel C-CAN, 8-channel LIN-USART, 32-channel 10-bit ADC, 205 GPIOs, and operates from −40°C to +125°C at up to 100 MHz core frequency with 3–5 V supply.
For engineers reviewing the MB91F469GAPB-GS-K6 datasheet, MB91F469GAPB-GS-K6 pinout, MB91F469GAPB-GS-K6 application, or MB91F469GAPB-GS-K6 equivalent, key selection criteria include CAN/LIN coexistence, high-pin-count BGA-320 packaging, flash-protected 2112 KB program memory, and support for safety-critical vehicle subsystems requiring AEC-Q100 alignment.
Technical Context
The MB91F469GAPB-GS-K6 implements the FR60 CPU - a five-stage-pipeline, load/store 32-bit RISC core with 16-bit fixed-length instructions, 1-instruction-per-cycle execution, and hardware multiplier (3-cycle 16-bit, 5-cycle 32-bit). It supports full Harvard architecture for concurrent instruction and data access.
On-chip peripherals include six independent C-CAN controllers (1 Mbps, 128 message buffers), eight LIN-USART channels (four with FIFO), four I²C interfaces (400 kbps), and a 5-channel DMAC with fly-by transfer between external I/O and memory using 8/16/32-bit data widths.

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 |
|---|---|---|---|
| RH850/F1K (Renesas) | 400 MHz dual-core, 16 MB Flash, ISO 26262 ASIL-D ready; no integrated LIN-USART; requires external transceivers. | Targeted at higher-ASIL domains (e.g., brake control); lacks native LIN support, increasing BOM cost and layout complexity for body electronics. | Select when functional safety certification (ASIL-D) is mandatory and LIN is handled externally or omitted. |
| S32K144 (NXP) | ARM Cortex-M4F core, 1 MB Flash, 128 KB RAM, single CAN FD, no LIN-USART; supports CAN FD but not legacy LIN 2.x protocol stack. | Optimized for gateway and low-end ECU roles; lacks dedicated LIN hardware, requiring software-based LIN bit-banging with higher CPU load and jitter. | Select for CAN FD migration paths where LIN is secondary or implemented via software abstraction layers. |
Compared with RH850/F1K and S32K144, MB91F469GAPB-GS-K6 uniquely combines native 6-CAN + 8-LIN hardware in a single die, enabling compact, cost-effective designs for mixed-protocol vehicle networks without sacrificing real-time determinism or extended temperature operation.

Manufacturer
Infineon Technologies is a German semiconductor manufacturer specializing in power management, automotive MCUs, and security solutions, with global R&D and manufacturing infrastructure serving Tier-1 automotive suppliers and industrial OEMs.
This device belongs to the CY91460G series - a family of high-reliability 32-bit RISC microcontrollers engineered specifically for automotive embedded control applications demanding real-time responsiveness, mixed-protocol connectivity (CAN/LIN/I²C), and operation across −40°C to +125°C.
FAQ
Is MB91F469GAPB-GS-K6 qualified to AEC-Q100?
Yes - MB91F469GAPB-GS-K6 is AEC-Q100 Grade 1 qualified (−40°C to +125°C ambient), with test reports confirming reliability for automotive powertrain and chassis applications. Its 0.18 μm CMOS process, built-in clock supervisor, and low-voltage detection circuit meet stress-test requirements for humidity, temperature cycling, and ESD.
Does it support CAN FD or only classical CAN?
MB91F469GAPB-GS-K6 implements C-CAN compliant with ISO 11898-1 (Classical CAN only), supporting up to 1 Mbps. It does not support CAN FD features such as flexible data-rate or extended payload length. For CAN FD, consider Infineon's newer AURIX™ TC3xx series.
What debug interface does it use?
The device uses JTAG boundary scan (IEEE 1149.1) with EDSU (Embedded Debug Support Unit) featuring 16 hardware breakpoints. It supports real-time trace via DSU4-compatible debug probes and integrates with Cypress/Infineon's PSoC Creator and ModusToolbox IDEs for flash programming and runtime analysis.
Can the internal 100 kHz RC oscillator be used as system clock source?
Yes - the internal 100 kHz RC oscillator serves as a fail-safe clock source during main/sub-oscillator startup or failure. It can drive the CPU directly in low-power modes or feed the PLL for coarse-frequency operation, though it lacks the stability required for CAN bit timing or RTC accuracy.
