STC15F104E PDIP-8

STC15F101E series is a single-chip microcontroller based on a high performance 1T architecture 80C51 CPU, which is produced by STC MCU Limited. With the enhanced kernel, STC15F101E series execute instructions in 1~6 clock cycles (about 6~7 times the rate of a standard 8051 device), and has a fully compatible instruction set with industrial-standard 80C51 series microcontroller. In-System-Programming (ISP) and InApplication- 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-valatile data in Flash memory while the application program is running. the STC15F101E series has 8 interrupt sources, on-chip high-precision RC oscillator and a one-time enabled Watch-Dog Timer.

Features

Enhanced 80C51 Central Processing Unit, faster 6~7 times than the rate of a standard 8051

Operating voltage range: 3.8 ~ 5.5V or 2.4V ~ 3.6V (STC15L101E series)

Operating frequency range: 5MHz ~ 35MHz, is equivalent to standard 8051: 60 ~ 420MHz

A high-precision internal RC oscillator with temperature drifting ±1% (-400C~+850C)

internal RC oscillator with adjustable frequency to 5.5296MHz/11.0592MHz/22.1184MHz/33.1776MHz

On-chip 128 bytes RAM and 0.5K~6K bytes code flash with flexible ISP/IAP capability

EEPROM function

Code protection for flash memory access

Two 16-bit timers/counters — Timer 0 / Timer 1 with mode 0 (16-bit auto-reload mode), mode 1 (16-bit timer mode) and mode 2 (8-bit auto-reload mode)

simulate UART can be realized by P3.0,P3.1 and Timers

8 interrupt sources

One 15 bits Watch-Dog-Timer with 8-bit pre-scalar (one-time-enabled)

Three power management modes: idle mode, slow down mode and power-down mode

 Power down mode can be woken-up by external INTx pin (INT0/P3.2, INT1/P3.3, INT2 , INT3, INT4 )

Excellent noise immunity, very low power consumption

Support 2-wire serial flash programming interface.(GND/P3.0/P3.1/VCC)

Programmable clock output Function. T0 output the clock on P3.5, T1 output clock on P3.4.

6 configurable I/O ports are available and default to quasi-bidirectional after reset. All ports may be

independently configured to one of four modes : quasi-bidirectional, push-pull output, input-only or opendrain output. The drive capability of each port is up to 20 mA. But recommend the whole chip's should be less than 70 mA.

Package type: SOP-8,DIP-8
