Single chip microcontroller, LPC2106FBD48, NXP
This microcontroller due to its tiny size and low power consumption is ideal for applications where miniaturization is a key requirement, such as access control and point-of-sale. With a wide range of serial communications interfaces and on-chip SRAM options up to 64 kB, it is very well suited for communication gateways and protocol converters, soft modems, voice recognition and low end imaging, providing both large buffer size and high processing power.
