Description：
The ARMKEY is a system on a board module, housed in a DIP-40 package. It uses a high performance and low power consumption ARM chip as like a main control unit. This chip can speed up to 60MHz via internal on-chip PLL. There are 32 general purpose input/output pins at most, each pin can be multiplex with on-chip peripheral specific function pin. This ARM chip has many on-chip peripheral units：including two Capture/Comapre/ Timers, a 32-bits GPIO, a PWM, a RTC, a IIC serial interface, a SPI serial interface, two UARTs, a Watch-Dog Timer and a system control unit. For the on-chip memory, it includes 128K bytes Flash and 16K~64K bytes SRAM. There are many kinds of chip configuration modes could be used：including ISP, IAP and JTAG.
There are a USB chip for communicating and power-supplying to the module stand alone. It can easily use Windows’ hyper-terminal to developing any application with this module in an interactive mode real-time. An additional serial EEPROM is option for setting customer’s USB-ID or holding private data.
For other special design in this module, it uses an 8051-compatible pin assignment for replace any exist 8051 application easily. It lets you have 8051’s functions and have ARM’s high performace.
