The STC11F02 series is a single-chip microcontroller based on a high performance 1T architecture 80C51 CPU, which is produced by STC MCU Limited. With the enhanced kernel, STC11/10xx 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 microcontrollers .

Features

1. On-chip 1280/512/256 byte RAM
2. Be capable of addressing up to 64K byte of external RAM
3. Dual Data Pointer (DPTR) to speed up data movement (except STC11F01 series)
4. Code protection for flash memory access
5. Excellent noise immunity, very low power consumption
6. Two 16-bit timer/counter, as the same as Timer0/Timer1 of standard 8051
7. 6 vector-address, 2 level priority interrupt capability
