More info

STC89xx series, which is produced by STC MCU Limited, is a 8-bit single-chip microcontroller with a fully compatible instruction set with industrial-standard 80C51 series microcontroller. There is 64K bytes flash memory embedded for application program, which is shared with In-System-Programming code.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-volatile data in Flash memory while the application program is running. There are 1280 bytes or 512 bytes on-chip RAM embedded that provides requirement from wide field application. The user can configure the device to run in 12 clocks per machine cycle, and to get the same performance just as he uses another standard 80C51 device that is provided by other vendor, or 6 clocks per machine cycle to achieve twice performance. The STC89xx series retain all features of the standard 80C51. In addition, the STC89xx series have a extra I/O port (P4 ), Timer 2, a 8-sources, 4-priority-level interrupt structure, on-chip crystal oscillator,and a one-time enabled Watchdog Timer.

Features:

  • Enhanced 80C51 Central Processing Unit ,6T or 12T per machine cycle
  • Operation voltage range: 5.5V~3.3V (STC89C series) or 2.0V~ 3.6V (STC89LE series)
  • Operation frequency range: 0- 48MHz@12T, or 0-24MHz@6T
  • On-chip 4/8/13/16/20/32/64K FLASH program memory with flexible ISP/IAP capability
  • On-chip 1280 byte / 512 byte RAM
  • Be capable of addressing up to 64K byte of external RAM
  • Be capable of addressing up to 64K bytes external memory
  • 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)
