M200 Chipset info

[turbodog]

I cracked my M250 open to see what hardware is used:

Main processor/"System on Chip" (SOC): Telechips TCC 770
www.telechips.com

Couldn't get any detailed info, their website requires a logon just to see the datasheet. Possibly because they are in the process of being sued by SigmaTel for patent infringement. I emailed asking how to get a software developer's kit, but don't expect an answer. They are not set up to sell product into the USA. Anyone have a friend in Hong Kong that would front for me in getting one ?
Anyway, here's the info I COULD find:


TCC77x Series are system LSI for digital audio player based on the ARM946E-S, ARM'sproprietary 32-bit RISC CPU core.

it can decode and encode MP3 or other types of audio/voice compression/ decompression standards by software based architechure. The on-chip USB 2.0 compliant controller enables the data transmission between a personal computer and storage device such as NAND flash, HDD, SD,MMC etc.

Applications

Portable MP3 player (WMDRM10)
Mobile MP3 phone
Juke Box (Audio & Photo)
Portable MP3 Karaoke
Digital Internet Radio Server
Electronic Dictionary
Personal Multimedia Player (Audio/Image/Video)
Multimedia Storage Device


SDK

Provides Reference Solution including H/W and S/W
Provides World-first proven JANUS DRM(WMDRM 10 - PD) Solution
Supports various Audio & Video codec
MP3 decoding/encoding
WMA decoding/encoding
OGG decoding
ADPCM decoding/encoding
JPEG decoding
MPEG4-SP decoding
Supports MSC (Mass Storage Class) & MTP (Media Transfer Protocol)
Supports Meta-data Browsing

Features

ARM946E-S CPU core (4KB cache, up to 120MHz), 0.13um process
- Core : 1.1V ~ 1.3V, I/O : 1.8V ~ 3.3V
4K bytes of internal boot ROM with various boot procedure (NAND, UART, USB, EHI) and security
64K bytes of internal SRAM for general usage
4K bytes of data TCM (Tightly Coupled Memory) for fast data access
On-chip peripherals
- USB2.0 Device / USB1.1 Host
- ECC generator for SLC and MLC NAND Flash
- General purpose 8 channel 10-bit ADC
- RTC (Real Time Clock) for battery backup
- EHI (External Host Interface) for parallel host interface
Dedicated Memory Interfaces: SD ,MMC, SLC / MLC NAND Flash , IDE I/F for HDD
Embedded 8Mbit Nor Flash ,16Mbit SDRAM, High Performance Audio Codec Options


Besides the Telechips part, here are the other main chunks of silicon:

TI TLV320AIC23B Stereo codec and headphone amp (not sure why this is needed, as the telechips supposedly has the codec built in? Maybe just for the headphone amp)

ESMT M12S16161A 1M X 16 DRAM

Flash is Samsung... I didn't bother with the chip IDs

Philips TEA5767 FM radio

and a couple I was unable to track down from the markings:

59TI
AIP

and


AZ-76
VOB

..... and, yes, I got it back together and working perfectly

Thanks for investigating and documenting that info.

I think I’m going to start actively requesting that Sandisk impliment OGG playback on the m200.

RDS would be nice too - according to an old 2004 Philips press release

Philips’ complete portfolio of FM radio solutions gives manufacturers the opportunity to target specific market segments. This flexibility is of particular importance with the decreasing lifespan of mobile phones and other devices due to accelerating innovation cycles and increased competition worldwide.

The external component count has been reduced dramatically in the new FM and FM+RDS products. The size of the FM radio TEA5761 has been reduced from 150 mm2 to a 50mm2 PCB area. The FM with integrated RDS demodulator and decoder TEA5764 covers a total PCB area of only 70 mm2. The two versions are realized in wafer level chips-scale (WL-CSP) packaging. Philips is the first company to achieve this level of integration. The FM radio and FM+RDS are fully pin compatible, which means that manufacturers benefit from the ability to make last-minute easy swaps.

The FM radio TEA5767 remains in production. The AM/FM TEA5777 appears in the HVQFN48 and has 200mm2 PCB.

With a firmware upgrade I can see this is very possible since the radio chipset in the M200 series appear to be pin for pin compatible with Philips other radio chipsets. (ie TEA5764 FM +RDS)
