STC Microcontroller STC8H8K64U-45I-SKDIP28

Description

Core Specs:  Ultra-high speed 8051 Core with single clock per machine cycle, which is called 1T and the speed is about 12 times faster than traditional 8051  Fully compatible instruction set with traditional 8051  22 interrupt sources and 4 interrupt priority levels  Online debugging is supported  Operating voltage 1.9V~5.5V  Operating temperature -40℃~85℃ (The chip is produced in -40℃~125℃ process. Please refer to the description of the electrical characteristics chapter for applications beyond the temperature range)  Flash memory Up to 64Kbytes of Flash memory to be used to store user code  Configurable EEPROM size, 512 bytes single page for being erased, which can be repeatedly erased more than 100 thousand times.  In-System-Programming, ISP in short, can be used to update the application code. No special programmer is needed.  Online debugging with single chip is supported, and no special emulator is needed. The number of breakpoints is unlimited theoretically.  SRAM 128 bytes internal direct access RAM (DATA, use keyword data to declare in C language program)  8192 bytes internal extended RAM (internal XDATA, use keyword xdata to declare in C language program)  1280 bytes USB Data RAM  Internal high precise RC clock IRC(IRC for short, ranges from 4MHz to 45MHz), adjustable while ISP and can be divided to lower frequency by user software, 100KHz for instance.  Error:±0.3% (at the temperature 25℃) -1.35%～+1.30% temperature drift (at the temperature range of
