STC offers free developing tools for it's 8051 microcontrollers

STC offers free thumb USB In-System programming tool for their STC series 8051 based microcontroller. STC MCU is now the world's largest 8051 microcontroller family.
Feb. 21, 2011 - PRLog -- STC Technology Ltd. ,  a leading 8051 based microcontroller provider, has announced that they are going to offer free develope tools for all new customers. The tools included thumb USB ISP programmer, Windows ISP softwares for STC10, STC11, STC12 and STC15 series microcontrollers and controller data base file for Keil uVersion 2.0 and 3.0. These tools enable developers to compile and siumlate the STC microcontrollers in Keil IDC and download the program into flash with in a few seconds.

About STC Technology Ltd: STC is a Chinese IC design company. The major product line is enhanced 8051 based microcontroller. Now there are more than 1000 different products in 5 series: STC10, STC11, STC12, STC15, STC89. All STC 8051 microcontrollers are based on a high performance 1T architecture 8051 CPU core. With the enchanced kernal, STC series excute instructions in 1 to 6 clock cycles, (about 6-8 times faster than conventional 8051 device), and have a fully compatible instruction set with industrial-stand 80C51 mcu. In-System_Programming (ISP) and IN-Application_Programming (IAP) enable the developers to upgrade the program and data in system. In addition, the STC mcus have a extra I/O port (P4), a 6-sources 2 priorityy level interrupt structure, on-chip oscillator and a watchdog timer.

Features of STC8051 microcontroller:
- Enchanced 80C51 CPU, 1T per machine cycle, 6-8 timers faster than conventional 8051
- 0.5-62K on-chip flash ROM
- up to 2048KB SRAM
- Be capable of addressing up to 64KB of external RAM
- Dual data pointer
- Ultra safe code protection for flash ROM
- 6 vector address, 2 level priority interrupt
- Up to 3 UART with hardware address recognition, frame-error detection and baud-rate generator
- Internal oscillator
- 3 power management modes, Power consumption is less than 1uA in power down mode
- Up to 40 programmable IO
- 8 to 48Pins, DIP/PLCC/QFN/SOP/DIP/SSOP package
- Highly EDS protecting

Due to the rappid progressing of China's huge market, STC is now the worlds largest 8051 microcontroller family. Thanks for the huge annually selling quantity, STC is also the most cost effective MCU in the industry. It will lower down the cost dramatically when improving the performance significantly.
