Microchip Technology PIC16LC74B-04/L Microcontroller

The PIC16LC74B-04/L is a powerful 8-bit microcontroller from Microchip Technology, designed to offer a robust solution for embedded systems requiring low power consumption and high performance. This versatile microcontroller is ideal for a wide range of applications, from industrial control systems to consumer electronics, thanks to its rich set of features and peripherals.

The PIC16LC74B-04/L operates at a clock speed of 4 MHz, providing a balanced combination of processing speed and power efficiency. It is equipped with 7 KB of program memory and 192 bytes of RAM, allowing for the storage and execution of complex programs and algorithms. The device also includes an EEPROM with 128 bytes of data memory, which is perfect for storing non-volatile data that must be preserved between power cycles.

One of the standout features of the PIC16LC74B-04/L is its integrated peripherals. It boasts a 10-bit analog-to-digital converter (ADC) with 8 channels, enabling the microcontroller to interface with analog sensors and convert their signals into digital values for processing. Additionally, it includes two Capture/Compare/PWM modules, which are essential for tasks like motor control, signal measurement, and pulse width modulation for LED dimming.

The microcontroller also features a synchronous serial port (SSP) with SPI and I²C support, allowing for easy communication with other microcontrollers, sensors, and peripherals. The inclusion of two Enhanced Universal Synchronous Asynchronous Receiver Transmitters (EUSART) provides full-duplex serial communication, which is vital for applications requiring data exchange with computers, networks, or other serial devices.

For safety and reliability, the PIC16LC74B-04/L is equipped with a Watchdog Timer (WDT) and brown-out detection, ensuring that the system can recover from unexpected conditions like power drops or software lock-ups. It also supports power-saving modes, such as Sleep and Idle, to further reduce power consumption when the full operation of the microcontroller is not required.

In a 44-pin PLCC (Plastic Leaded Chip Carrier) package, the PIC16LC74B-04/L is a compact, yet powerful microcontroller that provides a scalable option for designers looking to balance performance with power constraints. Its comprehensive feature set and connectivity options make it an excellent choice for a multitude of embedded system applications.
