Infineon Technologies MB9EF226PMC-GSK5E2

Overview

MB9EF226PMC-GSK5E2 from Infineon Technologies (formerly Cypress) is an automotive-grade Arm® Cortex®-R4 microcontroller with 2 MB internal flash, 208 KB ECC-protected RAM, and integrated 2D graphics engine for TFT instrument cluster control. It delivers 205 DMIPS at up to 128 MHz via internal PLL, supports dual CAN, 50-channel 10-bit ADC, and operates from −40 °C to +105 °C in LQFP-176 package.

For engineers reviewing the MB9EF226PMC-GSK5E2 datasheet, MB9EF226PMC-GSK5E2 pinout, MB9EF226PMC-GSK5E2 application, or MB9EF226PMC-GSK5E2 equivalent, key selection criteria include real-time safety features (TPU, MPU, PPU, CRC), graphics subsystem (IRIS-SDL, 1 MB VRAM, 40 MHz pixel clock), and automotive interface support (LIN-USART, SMC, RSDS/TTL display outputs).

Technical Context

The device implements a dual-issue, superscalar 8-stage pipeline Cortex-R4 core with 8 KB I-Cache and 8 KB D-Cache, SECDED ECC on TCM and AXI RAM, and tightly coupled memory architecture enabling deterministic real-time execution. Its clock system integrates a programmable PLL, spread-spectrum clock generator (SSCG) for graphics, and independent stabilization timers for all clock sources.

Safety-critical operation is enforced through multiple hardware protection units: Timing Protection Unit (TPU) with eight 24-bit deadline timers, Peripheral Protection Units (PPU) per bus bridge, and Memory Protection Units (MPU) with 12 configurable regions. The Secure Hardware Extension (SHE) provides AES encryption, TRNG, and secure key storage in a self-contained domain.

FAQ

What is the maximum operating frequency and how is it achieved?

The MB9EF226PMC-GSK5E2 achieves 128 MHz CPU operation using its on-chip Phase-Locked Loop (PLL), which multiplies an external 4–8 MHz crystal input. The PLL includes spread-spectrum clock generation (SSCG) to reduce EMI, and its output is validated for stability across −40 °C to +105 °C with built-in clock supervision and reset generation on out-of-spec conditions.

Does this MCU support AUTOSAR and ISO 26262 compliance?

While not pre-certified, the MB9EF226PMC-GSK5E2 provides foundational hardware features required for ASIL-B development: MPU, TPU, PPU, CRC on memory, watchdog with windowing, and dual-lockstep-capable peripherals. Customers implement AUTOSAR Basic Software modules and achieve ISO 26262 compliance through configuration, diagnostics, and safety analysis per their specific system architecture.

How is graphics memory managed and what interfaces support external display?

It integrates 1 MB of dedicated VRAM accessible via 64-bit AXI bus to the IRIS-SDL graphics engine. External display is driven through parallel RGB888 interface (GFX0_DISP[0..25]) with configurable TTL or RSDS output, supporting up to 40 MHz pixel clock. No external frame buffer is needed for resolutions ≤1024×1024 at 60 Hz.

What debug and trace capabilities are available?

The device supports Arm CoreSight debug and trace via standard 5-pin JTAG interface, with up to 16-bit trace data width. On-chip trace buffer captures instruction and data flow; breakpoints, watchpoints, and debug halt modes are fully supported. Trace clock (CLK_TRACE_PD2) is independently gated to minimize power impact during active tracing.
