ATMT MP170 1GB DAB/MP3 player

Introduction

As suspected, this appears to be very similar if not identical to the Logic Dax.

Hardware

  • Telechips TCC773L? CPU - ARM946E?-S CPU Core (4KB Cache, up to 120MHz)
  • Kwang Sung Electronics ARBP-8 DAB Module - contains an Integrant Technologies ITD3020 tuner and Telechips TCC320 decoder. This DAB module is only capable of receiving Band 3 (174-240MHz) broadcasts, not Band L (1452-1492MHz)
  • LCD module (seems to have an SSD1815 controller). Has the following markings:
      R G  M1-RGB  B
      0YOOO1B-38-AO2
  • Samsung K9K8G08U0A? 1GB NAND Flash

Differences with the Logic Dax

None of these seem to me to be of any importance, but for completeness:

DAB module is KSM-AEBP000S-800 6255 00-D-0PbF and not KSM-AEBP000S-800 6184 D-0PbF. It also does not appear to have an antenna. I'm not currently is a DAB Band III country so I can't test reception. Board version is 3306 instead of 2106

LCD is 0YOOO1B-38-AO2 and not 0YOOO1B-38-MO2

Flash is K9K8G08U0A? and not K9K8G08U0M?. Board version is 3506 cf. 1906.

USB

Conecting to USB without the NAND board attached gives the following in lsusb:
