Sony BDP-S390 is a mid-range Blu-ray player released in Feb 01, 2012.

 

Technical Specifications

This model contains the proprietary Sony CXD90007G-AA System-on-Chip (ARMv6I). Not much is much is known about this chip due to lack of datasheets and its proprietary nature. 

For memory, it contains two DDR3 SDRAM chips from Samsung:

Samsung K4B1G1646G-BCH9

• Type: DDR3 SDRAM
• Density: 1 Gigabit (organized as 64M x 16) (128 MB)
• Voltage: 1.5V (standard DDR3)
• Package: 96-ball FBGA (Fine-pitch Ball Grid Array)
• Speed bin: The "-BCH9" suffix indicates it's rated for DDR3-1600 (800 MHz clock, CL=11 timing, often labeled as PC3-12800)

Samsung K4B2G1646C-HCH9

• Type: DDR3 SDRAM
• Density: 2 Gigabit (organized as 128M x 16) (256 MB)
• Voltage: 1.5V
• Package: 96-ball FBGA
• Speed: The "-HCH9" suffix typically indicates DDR3-1333 (667 MHz clock) or similar bins from that era.

For local storage, it contains the Samsung K9F2G08U0C, a NAND flash memory chip.

• Type: SLC (Single-Level Cell) NAND flash – more reliable and durable than TLC/MLC, common in embedded/industrial devices like Blu-ray players.
• Density: 2 Gb = 256 MB raw capacity
• Organization: x8 interface, typically in a 48-pin TSOP1 package (though it looks like FBGA here, common variant)
• Voltage: 3.3V

Despite being a Profile 2.0 (BD-Live) player, it's local storage size is only 256 MB and not 1 GB.

It also contains a Richtek RT8293AL, a 3A, 23V-input, 340kHz synchronous buck (step-down) DC-DC converter in a small SOP-8 exposed-pad package.

• Function: High-efficiency voltage regulator that steps down higher voltages (e.g., from the player's 12V or 19V power input) to lower rails like 3.3V or 1.8V needed by the SoC, memory, or other components.
• Features: Synchronous rectification for better efficiency, adjustable output, over-current/temperature protection, and a latch-off UVP mode (the "L" in RT8293AL likely denotes this variant).
• The bottom marking "ZSPDHR08" is a Richtek internal lot/date code (nothing publicly notable).

The player's single board chips

There's two other chips from Texas Instruments, Texas Instruments TPIC2050RDFDRG4, a 9-channel motor driver IC used in optical disc drives. The other one is marked with "1011047" and the TI logo, is the Texas Instruments SN1011047PWPR, a 14-pin HTSSOP (High Temperature Small Outline Package) integrated circuit; it is unknown what its purpose is. 

Two more chips from ROHM Semiconductor, BD80GA3WNUX-TR, is a single-output LDO (low dropout) regulator. It contains these makings, "80GA3W" with "1442". The other is the BD9328EFJ-E2, a synchronous step-down switching regulator with built-in power MOSFETs. It contains these markings, "DP328" with "1444".

 An interesting component is a quartz crystal resonator (commonly just called a crystal or clock crystal) from ECEC (ZheJiang East Crystal Electronic Co., Ltd., a Chinese manufacturer specializing in frequency control components). It contains the markings, ECEC 27.000CL1. "27.000" = 27 MHz exactly. It's a passive through-hole quartz crystal (HC-49S or similar low-profile package) — not an active oscillator (those have 4 pins and built-in circuitry). The board uses it with the Sony SoC's internal oscillator circuit to generate a precise 27 MHz master clock signal.

Features

Media Player: Plays many types of media from a USB or a local DLNA server. It doesn't show thumbnails or music albums on video and music files.

Super Audio CD playback: Sony & Phillip's proprietary surround sound CD format.

The player's XMB menu with apps and Gracenote enabled

Digital-Analog-Converter (dac) that converts digital audio to analog signals in stereo. This is often preferred for audiophiles who prefer natural sounds, and provides compatibility with legacy audio equipment.

This model formerly included online services such as the Sony Entertainment Network and an app store, that included Netflix, Prime Video, Hulu, and, many others. These web apps were powered by Opera 9 browser. Sony discontinued online services for this model on September 2025.

 It also includes a built-in web browser powered by Opera 9, it doesn't support modern websites that uses HTTPS connection, however you can browse websites that uses HTTP or local pages. It is capable of playing MP3 files, and opening .TXT files.

Gracenote was also supported, an online feature that fetches metadata for video and music including Blu-rays. However, the service for the player was shutdown in 2025. The player supports BD metadata but only displays the title and not the thumbnail.

Xross Media Bar (XMB): Sony's iconic UI used for the player's menu. Performance is not as smooth as the PS3's XMB with average frame rates at 15 FPS.

The player uses the embedded version of the Linux Operating System and contains many open source code:

List of Open Source Components:

Component	Version	Explanation
busybox	1.17.2	A lightweight suite of Unix-like command-line tools combined into a single executable, used for basic system management and scripting in embedded environments like this player.
DirectFB	1.2.7	A graphics library for hardware-accelerated rendering on embedded systems, handling display output, input devices, and basic UI elements without needing a full windowing system.
glibc	2.12.2	The GNU C Library, which provides essential C standard library functions for running applications on Linux, including memory management, string handling, and I/O operations.
libsoap	1.1.0	A library for SOAP (Simple Object Access Protocol) support, enabling web service communications like those used for streaming services or firmware updates.
linux	2.6.35	The main kernel used for the operating system.
linux-fusion	8.2.0	A customized Linux kernel module for enhanced multitasking and real-time performance in embedded devices, often used in media players for smoother operation.
lirc	0.8.5	Software for handling infrared remote control signals, allowing the player to receive commands from the IR remote.
mtd-utils	1.2.0	Tools for managing flash memory (Memory Technology Devices), such as reading, writing, or erasing NAND chips for local storage.
mtp	0.3.6	A library implementing the Media Transfer Protocol, used for transferring media files between the player and computers or other devices via USB.
sawman	1.4.0	A window manager extension for DirectFB, helping manage screen layers and compositing for graphical interfaces in embedded systems.
u-boot	2009.08	A popular open-source bootloader that initializes hardware and loads the OS during startup.
