Detailed Description

RK3126 is a Rockchip quad-core application processor in the Specialized ICs category. It is built for cost-effective smart devices such as tablets, HMI panels, and learning devices. It integrates CPU, GPU, memory interfaces, display, camera, audio, and rich I/O on a single chip for compact designs and fast time to market.

Key Features

Quad-core ARM Cortex-A7 class CPU for smooth basic computing and UI

Integrated Mali-400 class GPU for 2D/3D graphics acceleration

Video decode support suitable for mainstream HD playback (model-dependent)

Display interfaces including MIPI DSI and RGB/TTL LCD options

Camera interface (CSI) for single-sensor capture

Memory support for DDR3/LPDDR2 with eMMC/SD storage options

Connectivity and I/O including USB 2.0 OTG/Host, SDIO, SPI, I2C, UART, PWM, GPIO

Audio interfaces such as I2S/PCM for external codecs or audio subsystems

Touch controller support for capacitive or resistive touch (platform dependent)

Android and Linux software stack availability through Rockchip SDKs and ecosystem partners

Key Advantages

Proven, cost-effective SoC with broad market adoption and ecosystem support

Simple integration to reduce BOM and board size

Stable software platforms and tools to speed development

Flexible display and camera options for a wide range of products

Low power design suitable for handhelds and always-on devices

Strong community and third-party resources for faster troubleshooting and tuning

Packaging

Type QFP per listing

Case code 1180 per supplier listing

Material Molded epoxy package with plated leads, RoHS and REACH compliant

Outline Four-sided quad flat package footprint for easier hand or wave rework versus fine-pitch BGA

Lead pitch and pin count High-pin-count QFP with fine pitch (exact dimensions vary by sub-revision; confirm in datasheet)

Pin configuration Leads on four sides for dense I/O mapping; signals include memory, display, camera, audio, USB, and general-purpose interfaces

Moisture sensitivity MSL typical for plastic QFP; follow proper bake and reflow practices per datasheet

Thermal characteristics Passive cooling in many designs; use solid ground planes and optional heat spreader for sustained high-load operation; validate junction temperature with your enclosure

Electrical properties Typical multi-rail supplies including core rail around 1.0–1.2 V, memory rails around 1.5–1.8 V, and I/O rails up to 3.3 V depending on interface; refer to official datasheet for exact limits, ripple and sequencing

Lifecycle

Status Mature and widely deployed. Not announced as end-of-life at the time of writing, but it is an older platform. Availability can vary by region and revision.

Common equivalents or alternatives

- RK3126C A cost-down or revised variant of RK3126 for similar use cases. Check pinout and software compatibility.

- RK3128 Similar CPU generation with enhanced interfaces such as HDMI on some variants. Often used in TV boxes and smart displays.

- RK3229 Higher multimedia capability within Cortex-A7 class, better video decode performance. Usually BGA; board redesign likely.

- RK3326 Newer quad-core class with improved efficiency and graphics. Different architecture and package; redesign required.

Notes Cross-compatibility depends on PCB, pinout, firmware, and thermal design. If you need a form-fit-function match or a long-term supply plan, contact our sales team via the Y-IC website for the latest lifecycle and cross-reference guidance.
