Manufacturer: Microchip Technology

Categories: Microcontrollers

Quality Control: Learn More

Microchip Technology PIC® 16F Series PIC16F873A-E-ML is an 8-bit microcontroller featuring 7KB of FLASH program memory, organized as 4K x 14 words. This component operates at a maximum speed of 20MHz and includes 192 bytes of RAM and 128 bytes of EEPROM. Connectivity options include I2C, SPI, and UART/USART interfaces. On-chip peripherals such as Brown-out Detect/Reset, Power-On Reset (POR), Pulse Width Modulation (PWM), and Watchdog Timer (WDT) are integrated. It also incorporates a 5-channel, 10-bit Analog-to-Digital (A/D) converter. The device offers 22 programmable I/O pins and supports external oscillator types. Packaged in a 28-QFN (6x6) with an exposed pad, the PIC16F873A-E-ML is designed for surface mount applications operating within a temperature range of -40°C to 125°C and a supply voltage of 4V to 5.5V. This microcontroller is commonly utilized in industrial control, automotive, and consumer electronics applications.

Microcontroller FAQs

A microcontroller is a compact integrated circuit that combines a processor, memory, and input/output peripherals for embedded control applications.

Microcontrollers execute programmed instructions to process sensor inputs and control outputs such as motors, displays, and communication interfaces.

Microcontrollers are commonly used in:

  • Automotive systems
  • Robotics
  • IoT devices
  • Industrial automation
  • Household appliances
  • Smart electronics

Microcontrollers integrate memory and peripherals on-chip for dedicated tasks, while microprocessors are designed for higher-performance computing systems requiring external components.
