External Memory Interface

4 Chip select Pins: (CS0~3) /CS0 for Nor flash /CS1 for pSRAM /CS2. Sub LCM or Melody IC (NC) /CS3. Main LCM We have verify many MCP supplier’s parts, including Spansion, Toshiba, Renesas, Intel.. Pay attention to: Renesas nor die or intel Tyax: /WP->GND Others nor die: /WP->Vmen

MCP decoder
R350 3 2 1 0 /CE_F2_88B /CE_F2 /CE_F2_73B

R350 is a jumper for option the different package MCP In order to support two die Flash MCP. Use EA23 decide which die selected. If 64Mb only, R303 = 0 ohm and U302 and R302 NC For the GPRS and multi-media application, we suggest to use the MCP with page mode.
