Overview

MB91F469GAPB-GS-K6E1 from Cypress Semiconductor is a 32-bit FR60 RISC microcontroller with integrated CAN (C-CAN), LIN-USART, and 10-bit ADC for automotive and industrial embedded control. It operates at up to 100 MHz core frequency, supports 3–5 V supply, −40°C to +125°C operation, and features 205 GPIOs, 6-channel CAN, and 32-channel ADC with 1 µs conversion time.

For engineers reviewing the MB91F469GAPB-GS-K6E1 datasheet, MB91F469GAPB-GS-K6E1 pinout, MB91F469GAPB-GS-K6E1 application, or MB91F469GAPB-GS-K6E1 equivalent, key selection criteria include CAN/LIN coexistence, BGA-320 package compatibility, real-time interrupt latency (6-cycle save), and flash security support in production-grade automotive ECUs.

Technical Context

The MB91F469GAPB-GS-K6E1 implements the FR60 CPU core with five-stage pipeline, Harvard architecture, and instruction-level multiplier (3-cycle 16-bit, 5-cycle 32-bit). It integrates dual-clock supervision (main 4 MHz / sub 32 kHz), PLL clock modulation, and hardware RTC calibration using sub-oscillator drift correction.

Its peripheral set includes 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 supporting fly-by transfers between external I/O and memory with 8/16/32-bit data width selection.

FAQ

What is the maximum operating frequency of the MB91F469GAPB-GS-K6E1 core?

The MB91F469GAPB-GS-K6E1 achieves a maximum core frequency of 100 MHz when powered by a 1.8 V internal regulator output voltage. This frequency is sustained across the full −40°C to +125°C operating range and enables sub-microsecond interrupt response and deterministic real-time execution for safety-critical tasks.

Does this microcontroller support both CAN and LIN communication simultaneously?

Yes. The MB91F469GAPB-GS-K6E1 integrates six independent C-CAN controllers and eight LIN-USART channels (four with FIFO), allowing concurrent CAN and LIN communication without resource contention. Each interface has dedicated message buffers and clock domains, verified in production automotive gateways.

What package type and pin count does MB91F469GAPB-GS-K6E1 use?

MB91F469GAPB-GS-K6E1 uses a 320-pin plastic BGA (BGA-320P-M06) package with 0.8 mm pitch and 20 × 20 mm footprint. Pin assignments are documented in the official Cypress datasheet (002-04606 Rev. *A), including JEDEC-compliant I/O grouping and dedicated power/ground banks.

Is flash memory programming security supported on this device?

Yes. The MB91F469GAPB-GS-K6E1 includes on-chip flash protection features: write/erase lock bits, flash CRC calculation hardware, and secure boot verification. These mechanisms prevent unauthorized firmware access or modification and are enabled via dedicated register settings per Cypress application note AN95127.
