STC15W101** is a microcontroller manufactured by **STC Micro**.

The STC15W101 is a microcontroller manufactured by STC Micro. Below are its factual specifications, descriptions, and features:

Manufacturer:

STC Micro (STC)

Key Specifications:

  • Core: 8051 (Enhanced 1T architecture)
  • Operating Frequency: Up to 35 MHz
  • Flash Memory: 1KB (for program storage)
  • RAM: 256 bytes
  • EEPROM: None
  • GPIO Pins: 8 pins (P3.0–P3.7)
  • Timers:
  • 2x 16-bit timers (Timer0, Timer1)
  • 1x watchdog timer
  • ADC: None
  • PWM: None
  • UART: 1 (Supports serial communication)
  • SPI/I2C: None
  • Operating Voltage: 2.4V–5.5V
  • Power Consumption: Low-power modes available (Idle & Power-down)
  • Package: SOP-8

Features:

  • 1T 8051 Core: Faster execution than traditional 12-clock 8051 MCUs.
  • High Noise Immunity: Robust design for industrial environments.
  • Internal RC Oscillator: No external crystal required (adjustable).
  • Reset Circuit: Built-in power-on reset (POR) and brown-out detection (BOD).
  • ISP (In-System Programming): Supports serial programming via UART.
  • Wide Voltage Range: Operates from 2.4V to 5.5V.
  • Industrial-Grade: High reliability for harsh conditions.

Applications:

  • Simple control systems
  • Consumer electronics
  • Sensor interfaces
  • LED control
  • Basic automation

Note:

The STC15W101 is a minimal-feature MCU suitable for cost-sensitive, low-complexity applications. It lacks an ADC, PWM, and extensive peripherals compared to higher-end STC models.
