Part Review and Datasheet Update

flux

Completed the RK809-5 part review and added the datasheet/metadata to the project properties. I created the full detailed report here: RK809-5 Part Review.
Key flags: the QFN-68-EP(7x7) footprint and 69-pad count match the datasheet, but pins 42/43 are named MIC1N/MIC1P while the datasheet table uses MICIN/MICIP, and most pins still have unspecified pin types/descriptions. The footprint uses a single large exposed-pad paste area; I’d recommend segmented paste and board-level thermal vias for robust assembly/thermal performance.

Set the pin type and datasheet-based pin description for every terminal. Group all terminals into logical symbol sections according to their functions and the datasheet recommendations. Ensure that pin names, pin numbers, pin types, descriptions, and section assignments are fully consistent with the official datasheet.

I’ll update every RK809-5 terminal with datasheet pin type, pin description, and section assignment, rename the microphone pins to the datasheet table names, then verify the terminal set afterward.

flux

Done. I updated all 69 RK809-5 terminals with datasheet-based pin numbers, standard pin types, pin descriptions, and single logical section assignments.
I also renamed MIC1N → MICIN and MIC1P → MICIP to match the official datasheet pin table. Verification passed for terminal, terminal pin-number, and missing-property part review checks with no open warnings/errors.

RK809-5 thumbnail
QFN-68-EP(7x7) Power Management - Specialized RoHS
The RK809-5 is a highly integrated Power Management Integrated Circuit (PMIC) from Rockchip designed for multi-core processor systems and embedded applications. It provides a complete power management solution by integrating multiple high-efficiency DC-DC buck converters, LDO regulators, power sequencing logic, battery fuel gauging, RTC functionality, and audio codec capabilities into a single device. The RK809-5 is commonly used alongside Rockchip SoCs in single-board computers, tablets, AIoT devices, and industrial embedded systems.
Key Features
Five high-efficiency synchronous buck converters with fast transient response. Nine low-dropout (LDO) voltage regulators for powering sensitive analog and digital circuits. Integrated battery fuel gauge for battery capacity monitoring. Configurable power-up and power-down sequencing (OTP programmable). Dynamic Voltage Scaling (DVS/DVFS) support via I²C interface. Integrated Real-Time Clock (RTC) with 32.768 kHz crystal oscillator support. Two integrated load switches for peripheral power control. Over-current, over-voltage, and thermal protection features. Built-in audio CODEC with headphone driver and Class-D amplifier support. Designed to minimize external component count and simplify power system design. QFN-68-EP (7 mm × 7 mm) package.
