Product>>8051 MicroController>>STC15W1K16S series


Features:

 

  • Enhanced 8051 Central Processing Unit, 1T, single clock per machine cycle, faster 8~12 times than the rate of a traditional 8051.
  • Operating voltage range: 5.5V ~ 2.5V.
  • On-chip 16K/24K/29/31.5K FLASH program memory with flexible ISP/IAP capability, can be repeatedly erased more than 100 thousand times
  • Large capacity of on-chip 1024 bytes SRAM: 256 byte scratch-pad RAM and 768 bytes of auxiliary RAM
  • Be capable of addressing up to 64K byte of external RAM
  • On-chip EEPROM with large capacity can be repeatedly erased more than 100 thousand times.
  • Dual Data Pointer (DPTR) to speed up data movement
  • ISP/IAP, In-System-Programming and In-Application-Programming , no need for programmer and emulator.
  • Internal hghly reliable Reset with 16 levels optional threshold voltage of reset, external reset curcuitcan be completely removed
  • Internal high- precise R/C clock with¡À1% temperature drift(-40~+85°C) while 5¡ë in normal temperature and wide frenquency adjustable between 5MHz and 35MHz (5.5296MHz / 11.0592MHz / 22.1184MHz / 33.1776MHz).
  • Internal high- precise R/C clock(¡À0.3%) with ¡À1% temperature drift (-40~+85°C) while ¡À0.6% (-20~+65¡ãC) in normal temperature and wide frenquency adjustable between 5MHz and 35MHz (5.5296MHz / 11.0592MHz / 22.1184MHz / 33.1776MHz)
  • No need external crystal and reset, and can output clock and low reset signal from MCU.
  • Operating frequency range: 5- 35MHz, is equivalent to traditional 8051:60~420MHz.
  • A high-speed asynchronous serial port----UART( can be used simultaneously and regarded as 3 serial ports by shifting among 3 groups of pins):
    UART1(RxD/P3.0, TxD/P3.1) can be switched to (RxD_2/P3.6, TxD_2/P3.7), also can be switched to (RxD_3/P1.6, TxD_3/P1.7).
  • A high-speed synchronous serial peripheral interface----SPI.
  • Support the function of Encryption Download (to protect your code from being intercepted).
  • Support the function of RS485 Control
  • Code protection for flash memory access, excellent noise immunity, very low power consumption
  • Power management mode: Slow-Down mode, Idle mode(all interrupt can wake up Idle mode), Stop/Power- Down mode.
  • Timers which can wake up stop/power-down mode: have internal low-power special wake-up Timer.
  • Resource which can wake up stop/power-down mode are:
    INT0/P3.2, INT1/P3.3 (INT0/INT1, may be generated on both rising and falling edges), INT2/P3.6, INT3/P3.7, INT4/P3.0 (INT2 /INT3/INT4, only be generated on falling edge); pins RxD; pins T0/T1/T2(their falling edge can wake up if T0/T1/T2 have been enabled before power-down mode, but no interrupts can be generatetd); internal lowpower special wake-up Timer. threee 16-bit reloadable Timers/Counters(T0/T1/T2, T0 and T1 are compatible with Timer0/Timer1 of traditional 8051), T0/T1/T2 all can independently achieve external programmable clock output (3 channels).
  • Programmable clock output function(output by dividing the frequency of the internal system clock or the input clock of external pin):
    ¢ÙThe Programmable clock output of T0 is on P3.5/T0CLKO (output by dividing the frequency of the internal system clock or the input clockof external pin T0/P3.4)
    ¢ÚThe Programmable clock output of T1 is on P3.4/T1CLKO (output by dividing the frequency of the internal system clock or the input clock of external pin T1/P3.5)
    ¢ÛThe Programmable clock output of T2 is on P3.0/T2CLKO (output by dividing the frequency of the internal system clock or the input clock of external pin T2/P3.1)
    Three timers/counters in above all can be output by dividing the frequency from 1 to 65536.
    ¢ÜThe Programmable clock output of master clock is on P5.4/MCLKO, and its frequency can be divided into MCLK/1, MCLK/2, MCLK/4.
    The master clock can either be internal R/C clock or the external input clock or the external crystal oscillator.
    MCLK is the frequency of master clock. MCLKO is the output of master clock.
  • One 15 bitsWatch-Dog-Timer with 8-bit pre-scaler (one-time-enabled)
  • advanced instruction set, which is fully compatible with traditional 8051 MCU, have hardware multiplication / division command.
  • 42/38/30/26 common I/O ports are available, their mode is quasi_bidirectional/weak pull-up(traditional 8051 I/O ports mode) after reset, and can be set to four modes: quasi_bidirectional /weak pull-up, strong pushpull/ strong pull-up, input-only/high-impedance and open drain.
  • the driving ability of each I/O port can be up to 20mA, but it don't exceed this maximum 120mA that the current of the whole chip of 40-pin or more than 40-pin MCU, while 90mA that the current of the whole chip of 16-pin or more than 16-pin MCU or 32-pin or less than 32-pin MCU.
  • Package:LQFP44, LQFP32,TSSOP20, SOP28, SKDIP28, PDIP40.
  • All products are baked 8 hours in high-temperature 175°C after be packaged ,Manufacture guarantee good quality.
  • In Keil C development environment, select the Intel 8052 to compiling and only contain < reg51.h >
