DC CharacteristiCs (STC11LEXX) Package Dimension 44 Version History 48 S]C11Fxx Technical Summa Features High Performance Enhanced 80C51 Unit Operating voltage range: 3.3V/5.0V Operating frequency range: 35Mhz (Max) On-chip 6K(max) FLASH program memory with flexible ISP/lAP capability On-chip 128+128 byte scratch-pad RAM Code protection for flash memory access Two 16-bit timer/counter(TO/T1) 6 vector-address, 4 level priority interrupt capability One enhanced UART with hardware address-recognition and frame-error detection function One 15 bits Watch-Dog- Timer with 8-bit pre -scalar(one-time-enabled)a Build In internal 6MHz RC oscillator Three power management modes: idle mode, slow down mode and power-down mode Power down mode can be woken-up by any external interrupt pins and any RXD interrupt Maximum 16 programmable I/O ports are available Package type: PDIP-16/18/20 SOP-16/18/20 STC11FXX Technical Summary General Description STC11FXX is a single-chip 8-bit micro-controller with instruction sets fully compatible with industrial-standard 80C51 series micro controller There is very excellent MCU kernel built in this device compared to general 80C51 MCU those take twelve oscillating cycles to finish an instruction, the device could take only one oscillating cycle to finish one instruction There is 6K(max) bytes flash memory embedded which could be used as program or data Also the In-System Programming and In-Application Programming mechanisms are supported. The data endurance of the embedded flash gets over 20,000 times, and 21 years data retention is guaranteed The operation frequency reaches at 35MHzS. An user can apply a crystal oscillator for the oscillating source, or alternatively uses the built in 6MHz Rc oscillator to save system cost The UART interfaces make the device convenient to communicate with the peripheral component, say talking to a personal computer via RS-232 port, or communicating with a serial memory. Up to 16 programmable GPlOs are available from STC11FXX The STC11Fxx is really the most efficient MCU adapted for simple control; say electronic scales, remote controller, security encoder/decoder, Video Player Controller, and user interface controller Order Information: Part Number Temperature Package Packing Operation Range Voltage STC11FXx-PDIP Industrial PD|P16/18/20 Tube 33v/5.0v STC11FXX-SOP Industrial soP-16/18/20 Tube 33v/50v X: voltage aa: rom size bbb: ADC, PWM. or none cc active frequency d: temperature"I"for industrial eeee: package type ff: pin count STC11FXX Technical Summary Pin Description Pin Definition Package Type MNEMONIC DESCRIPTION PDIP16PDIP-18PDIP-20 P1.0 10 12 Port1: General-purposed l/O with weak pull-up P1.1 11 12 13 resistance inside.
