Quality Control: Learn More

Microchip Technology PIC® 18C microcontroller PIC18C442T-E-PT is an 8-bit device featuring a 40MHz core. This OTP (One-Time Programmable) microcontroller offers 16KB of program memory (8K x 16) and 512 bytes of RAM. Connectivity options include I2C, SPI, and UART/USART. The PIC18C442T-E-PT integrates an 8-channel, 10-bit Analog-to-Digital converter. Available peripherals include Brown-out Detect/Reset, Low Voltage Detection (LVD), Power-On Reset (POR), Pulse Width Modulation (PWM), and Watchdog Timer (WDT). With 33 general-purpose I/O pins, this device is suitable for surface mount applications in a 44-TQFP (10x10) package. It operates within an extended temperature range of -40°C to 125°C and requires an external oscillator. This component is commonly utilized in industrial automation, 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.
