WinCE for i.MX25 Development Platform Introduction

[date:2010-3-16]

from:yuan ying   key:i.MX25  WinCE  EVK

   

   i.MX25 is ARM926EJS core, up to 400MHz, own 16KB I-Cache and 16KB D-cachealso 128KB SRAM as well. Meanwhile, which include both LCDC and SLCDC controller to support displayCE-ATA and P-ATA for mass storage, 12-bit 3 channels ADCthree I2C interfaces and five UART portsone Ethernet interfacetwo CAN interfacetwo SD/MMC interface.  Four timers and 4 channel PWM output, HS USB OTG+ FS USB Host with HF interface. CSI interface to support CMOS sensor input. Regarding display interface, which integrates LCDC and SLCDC connection. About system RAM, adopt DDR2 interfaceit’s new member for industrial application

i.MX25W is the system platform based on WinCE6.0treat FAT as system file  own i.mx258+64MB DDR2 system hardware, be able to boot up form SD card or NAND Flashalso i.MX25W including 7” LCD and resistance touch panel. Which built in i.MX25 all input/output resource. Which still adopt core board + bottom board structurethe components of CPU core board meet the industrial levelbe able to work at the temperature range of -40C to +85Cand storage temperature from  -55C to +125 degree. i.MX25W can widely applied for intelligent electric network, outdoor multimedia, industrial control and HMI, medical equipment and so on .Which is the good selection to power meter terminal, HMI of industry equipment, automotive ECU, medical device display interface

About the business model, YUANYING support core board selling and PCBA business model. And, promise to deliver the cost effective performance among ARM9 system to her customers.
