    Product>>8051 MicroController>>STC15F101W 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:
STC15F101W series: 5.5V ~ 3.8V (5V MCU).
STC15L101W series: 3.6V ~ 2.4V (3V MCU).
On-chip 2K/4K/5K/7K FLASH program memory with flexible ISP/IAP capability, can be repeatedly erased more than 100 thousand times.
on-chip 128 bytes SRAM
On-chip EEPROM with large capacity can be repeatedly erased more than 100 thousand times.
ISP/IAP, In-System-Programming and In-Application-Programming , no need for programmer and emulator. Internal hghly reliable Reset with 8 levels optional threshold voltage of reset, external reset curcuit can be completely removed
Internal high- precise R/C clock(±0.3%) with ±1% temperature drift (-40℃~+85℃) while ±0.6% (-20℃ ~+65℃) in normal temperature and widefrenquency 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: 0- 35MHz, is equivalent to traditional 8051:0~420MHz.
UART can be achieved by combining [P3.0/INT4, P3.1] with Timer

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/P3.4, INT3/P3.5, INT4/P3.0 ( INT2 / INT3/ INT4, only be generated on falling edge); pins T0/T2(their falling edge can wake up
if T0/T2 have been enabled before power-down mode,but no interrupts can be generatetd); internal low-power special wake- up Timer.
Two Timers/Counters----T0(are compatible with Timer0 of traditional 8051) and T2, T0/T2 all can independently achieve external
programmable clock output
Programmable clock output function(output by dividing the frequency of the internal system clock or the input clock of external pin):
The speed of external programmable clock output of 5V MCU is also not more than 13.5MHz, because the output speed of I/O port
of STC15 series 5V MCU is not more than 13.5MHz.
The speed of external programmable clock output of 3.3V MCU is also not more than 8MHz, because the output speed of I/O port
of STC15 series 3.3V MCU is not more than 8MHz.
① The Programmable clock output of T0 is on P3.5/T0CLKO (output by dividing the frequency of the internal system clock or the input clock
of external pin T0/P3.4)
② The 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)
Two timers/counters in above all can be output by dividing the frequency from 1 to 65536.
③ The Programmable clock output of master clock is on P3.4/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.
It is on MCLKO/P3.4 that the Programmable clock output of master clock of STC15 series 8-pin MCU (such as STC15F101W series).
However, it is on MCLKO/P5.4 that the Programmable clock output of master clock of other STC15 series MCU including 16-pin or more
than 16-pin MCU(such as STC15F2K60S2, STC15W4K32S4 and so on)
One 15 bits Watch-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.
6 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 push-pull/ strong pull-up, input-only/high-impedance and open drain.
the driving ability of each I/O port can be up to 20mA, but the current of the whole chip don’texceed this maximum 90mA.
If I/O ports are not enough, it can be extended by connecting a 74HC595. Besides, cascading several chips also can extend to dozens of
I/O ports.
Package: SOP-8, DIP-8, DFN-8.
All products are baked 8 hours in high-temperature 175℃ after be packaged, Manufacture guarantee good quality.
In Keil C development environment, select the Intel 8052 to compiling and only contain < reg51.h > as header
