CH551G 8Bit ADC - 8051 Core MCU - 32MHz - 16KB Flash - USB Microcontroller IC - SOP16

CH551G 8Bit ADC - 8051 Core MCU - 32MHz - 16KB Flash - USB Microcontroller IC - SOP16

Datasheet

An 8051 core Microcontroller with low cost packed in SOP16 package with tons of attractive features. SOP16 package makes it intesresting for small scale hand soldered projects where other cheap microcontrollers are difficult to use because of much smaller packages which are not easy to solder by hand. 

CH551 is an enhanced E8051 core MCU, compatible with MCS51 instruction set. 79% of its instructions are single-byte single-cycle instructions. The average instruction speed is 8~15 times faster than that of standard MCS51. CH551 supports up to 32MHz system clock frequency.
