Stc89C52Rc Microcontroller Minimum System Development Board

STC89xx collection, which is produced by way of STC MCU Limited, is a 8-bit single-chip microcontroller with a totally well matched training set with commercial-widespread 80C51 series microcontroller.

There is 64K bytes flash memory embedded for utility program, which is shared with In-System-Programming code. In-System- Programming (ISP) and In-Application-Programming (IAP) support the users to improve this system and records in system.

ISP lets in the person to down load new code with out disposing of the microcontroller from the actual give up product; IAP means that the tool can write non-risky statistics in Flash memory while the software application is strolling.

There are 1280 bytes or 512 bytes on-chip RAM embedded that offers requirement from extensive field application. The consumer can configure the tool to run in 12 clocks consistent with gadget cycle, and to get the identical overall performance just as he uses another standard 80C51 tool this is supplied by means of different dealer, or 6 clocks in step with device cycle to reap two times performance.

The STC89xx collection retain all functions of the standard 80C51. In addition, the STC89xx collection have a more I/O port (P4 ), Timer 2, a 8-assets, four-priority-stage interrupt structure, on-chip crystal oscillator,and a one-time enabled Watchdog Timer.

• Enhanced 80C51 Central Processing Unit ,6T or 12T per machine cycle
• On-chip 4/8/13/16/20/32/64K FLASH program memory with flexible ISP/IAP capability
• Dual Data Pointer (DPTR) to speed up data movement
• Three 16-bit timer/counter, Timer 2 is an up/down counter with programmable clock output on P1.0
• 8 vector-address, 4 level priority interrupt capability
• One enhanced UART with hardware address-recognition, frame-error detection function, and with self baud rate generator.
• One 15 bits Watch-Dog-Timer with 8-bit pre-scaler (one-time-enabled)
• integrate MAX810 — specialized reset circuit
• Three power management modes: idle mode and power-down mode
• Low EMI: inhibit ALE emission
• Power down mode can be woken-up by INT0/P3.2 pin, INT1/P3.3 pin, T0/P3.4, T1/P3.5, RXD/P3.0 pin, INT2/P4.3, INT3/P4.2
• Maximum 39 programmable I/O ports are available
• Four 8-bit bi-directonal ports; extra four-bit additional P4 are available for PLCC-44 and LQFP-44
• Operating temperature: -40 ~ +85oC (industrial) / 0~75oC (commercial)
