Hardware Components Overview of the iRiver H3XX

Board images

I snapped these while I had my player apart (for exercise really), hope they are remotely useful. This is an international H340. There are hardware differences between this and the US version (the wiring of the USB hosting port at the very least).

Unknown parts till now

LCD Display

We need to find out which display it is.

2 inch, 220x176, 18Bits/pix
This information is extract from here:

Also interesting, i find an LCD search engine here (linked to the LCD with the H3XX size):

It could be this one: LTM020A
Robin V
JamesLee: By comparing the smeared logo on the above label it has become clear that this module was made by Varitronix ( Currently, the only 176x220 2" module they make is the COG-T200MLF ( The similarity as far as where the pins are make the match very convincing. Unfortunately, the diagram doesn't outline which IC is used specifically. I have emailed them regarding the subject, and they responded saying that the controller is an HD66789R, attaching its datasheet.


RobinVet: I hope you're right, that would be a great news !

Datasheets and chip images

This hardware is used in the H3XX series

Motorola Coldfire Integrated Microprocessor SCF 5249VF140


140MHz coldfire


This is the CPU at the heart of the player

Samsung K4S561632E-TL75 - 4M x 16bit x 4Banks SDRAM LVTTL (256Mbit/32MB)


The same RAM as one in H1x0 series.

P23AF-LVX245 Low Voltage Octal Bidirectional Transceiver


20 pin

SST 39VF3201 Multi-Purpose Flash


Driver example:

UDA 1380TT Stereo Audio Decoder/Encoder


Philips UDA1380TT

Philips TEA 5767 Low-power FM stereo radio



LW052A Dual 4-channel analog multiplexer/ demultiplexer



MEC-AA4D4 30.0000 oscillator


Mercury Crystal Products 'MEC'

LVCH16245A - 16-Bit Bus Transceiver With 3-State Outputs



TPS61020 - TI DC/DC Converter - 5V version


10 pin (5 + 5 + 4 pins for the extra "PowerPAD" grounding)


This is a TPS61027DRC, the 5V version.

Philips ISP1362 - Single-chip USB On-The-Go controller


ISSI IS24C02 - 2kbit EEPROM

2 in number. One, located on the front side of the PCB, and other, located nearly to the CPU.
WAS IS25C02 but this is an SPI device, not I2c
Same as one of the H1x0's EEPROMs

Microsemi LX2201 - USB/AC/battery power supply / battery charger

This chip is on the front side of the PCB, between the plug for charging, battery connector and one 12.000MHz crystal oscillator.

It is likely from the die stamp that this is a Microsemi chip (MSC). Based on the description of the location of the chip and a search for iriver on the Microsemi site, it seems that this is the LX2201 linear battery charger circuit (for lithium ion batteries). This device is USB bus compliant. There should be an output from this device that provides the charging status (in process, level of charge, etc).

It is possible that this chip is not the same in the US and Euro versions, precipitating the "missing" devices around the US USB host. Since the MSC LX2201 is already USB compliant, it may well be that those components are to make up for the hardware shortcoming of the charging chip on the Euro model. Someone needs to confirm whether this chip is the same in the US and Euro devices (the one shown above may be the Euro chip? I'm going to see if MSC has a euro site).


Philips PCF50606HN/03A/N1Y Realtime Power Management Unit (PMU)


Here is located also the Realtime clock (RTC)

Philips TEA1211 DC/DC Converter


If we can trust ( this chip is TEA1211 regardless of it's mark being T1211

Btw, this combination (Philips PCF50606 PMU & Philips TEA1211 DC/DC conv.) is being used in iPods 3rd generation also (see

Definitely the same combination, (iPod 3rd Gen's PCB back - right-top), but the PMU is an older revision (PCF50605)

Cypress ISD-300LP USB 2.0 to ATA/ATAPI Bridge

Again info from (, because on the scan of the front side of PCB that i have there is a white sticker on the chip.
The same as H1x0's one.
HELP Can someone find a good picture of this chip? (It's located on the front side of PCB next to the SDRAM & the USB 1.1 Host controller)

Hard Drive

H340 - MK4004GAH 1.8-inch Hard Disk Drive info:

Differences between Northamerican (aka US) and International versions

Missing 5 components for the USB HOST power supply

Missing 5 components in the US version on the front side of the PCB. You can see them on the following pictures (marked with red, new one with blue):
International version:


US version:
(Note: the red wire is "modding" of US H3x0, i.e. it is missing in an untouched US player)

Location of these components:

Its almost sure that these (red) missing components are related to supplying power for the devices, attached to the USB host of ISP1362.

HELP Anyone who can help finding other hardware differences between the US and the International versions of H3x0?

Comparison between the hardware in H3x0 and H1x0 (H120 & H140) series

LinusNielsenFeltzing: Hmm. This means that we have yet not found a way to distinguish between the two remotes. The only difference between inserted and extracted remotes is the GPIO30 pin, which we already know is the remote detect pin. BTW, I have an H300 remote, so I'll work on this when I find the time. Good work anyway, guys!

HristoKovachev : I've just made my h300 remote to behave correctly (no detection of remote type, of course). If someone is interested, i can make a patch (or give full tonight

LinusNielsenFeltzing: Just add the patch to the patch tracker.

HristoKovachev: I'll do it ASAP. BTW, Rockbox for sure doesn't get all the info it can from the remote. I tryed my NON-lcd remote (the one that comes with Intl players) and the only change in View I/O Ports was when i press the Play/Pause button (which is also used for powering the unit on). As probably expected, the change is in GPIO1_READ (last byte 0x74->0x34). The remote also has "<<", ">>", Vol up and Vol Down (and hold switch). However, none of these caused any change in any of the readings.

MatthiasM: I can confirm the H300 NON-LCD remote behaviour. I added it to the above table... (Linus, do you own such a NON-LCD remote?)

LinusNielsenFeltzing: Yes I have one. It is very different from the LCD ones. I'll have a stab at it in due time.

BradCampbell: Non-LCD-remote ADC values Idle : 0xFF (Unplugged or no button pressed) ; Vol + : 0xE4 ; Vol - : 0xC8 ; <<| : 0x33 (skip back) ; |>> : 0x18 (skip forward ; HOLD : 0x00
