STC11F/10Fxx series are a single-chip microcontroller based on a high performance 1T architecture 80C51
CPU, which is produced by STC MCU Limited. With the enhanced kernel, STC11F/10Fxx series execute instructions in 1~6 clock cycles (about 6~7 times the rate of a standard 8051 device), and have a fully compatible instruction set with industrial-standard 80C51
series microcontroller . In-System-Programming (ISP) and In-Application- Programming (IAP) support the users to upgrade the program and data in system. ISP allows the user to download new code without removing the microcontroller from the actual end product; IAP means that the device can write non-valatile data in Flash memory while the application program is running. The STC11F/10Fxx series retain all features of the standard 80C51. In addition, the STC11F/10Fxx series have a extra I/O port (P4 ), a 6-sources, 2-priority-level interrupt structure, on-chip crystal oscillator,and a one-time enabled Watchdog Timer.
