SC1431, Raspberry Pi 5 – 4GB

The Raspberry Pi 5 features three newly designed chips, each specifically created to deliver a significant performance boost.

BCM2712

• BCM2712 is a cutting-edge 16-nanometer application processor from Broadcom, evolving from the 28-nanometer BCM2711 processor found in Raspberry Pi 4. It includes multiple architectural improvements.
• Powered by a quad-core 64-bit Arm Cortex-A76 processor clocked at 2.4GHz.
• Features 512KB per-core L2 cache and a 2MB shared L3 cache.
• The Cortex-A76 offers enhanced instructions per clock (IPC) and lower energy consumption per instruction than the Cortex-A72.
• Combining the newer architecture, higher clock speed, and advanced process geometry, Raspberry Pi 5 is significantly faster while using less power.

RP1

• Unlike previous Raspberry Pi models with a monolithic AP architecture, the RP1 provides a more efficient solution by offloading some I/O functions from the main processor.
• Earlier models relied on external devices (e.g., Via Labs VL805 USB controller, Microchip LAN951x USB hub), but this method became technically and economically unsustainable with advancements in process nodes.

DA9091

• The Renesas DA9091 “Gilmour” power-management IC (PMIC) is the third key component, supporting the BCM2712 and RP1 chips.
• Integrates eight separate switch-mode power supplies to manage the required voltages for the Raspberry Pi 5.
• Features a quad-phase core supply, delivering up to 20 amps of current to power the Cortex-A76 cores and other digital logic components in the BCM2712.
