The PIC16C74B-04I/P is a popular microcontroller due to its wide range of application fields, including automotive, industrial, consumer, and portable electronic applications. It is a member of the Microchip Technology family of microcontrollers and offers 8-bit (8-bit instruction words) and 12-bit (12-bit instruction words) instruction sets. The PIC16C74B-04I/P utilizes the enhanced mid-range core which contains 4K bytes of on-chip program memory, 124 bytes of RAM, three Capture/Compare/PWMs (CRC/CCP) modules, and four 8-bit timer/events.

The PIC16C74B-04I/P supports 14-pin Dual In-line Package (DIP) and 20-pin Quad Flat Pack (QFP) package types. It is also available in a 20-pin package with extended core RAM. All four I/O pins, 8 Port A pins, and 8 Port B pins have data access memory. All the I/O lines are high impedance capable and the PIC16C74B-04I/P features both full-port and bit-port operations.

The PIC16C74B-04I/P also features a PWM module which supports pulse width modulation modes. This allows the microcontroller to generate pulse width modulated signals, with duty cycle and control parameters adjustable via software. This module operates in two different operating modes, such as single and continuous. There is a two-cycle instruction cycle and a two-phase clock cycle, with the clock rate being adjustable by the user via software.

The PIC16C74B-04I/P comes equipped with a 16-bit Enhanced Capture/Compare/Pulse Width Modulation (ECCP) module which can be used to control motors and analog components. This module also features an 8-bit Timer/Counter/Event Trigger and an 8-bit Comparator/Capture, which can be used to capture input from external sources and convert it into a digital value or convert a digital value into analog voltage.

The PIC16C74B-04I/P operates at 3.3V/5V and is capable of both 20MHz and 6MHz instruction execution. It supports a wide range of analog and digital peripherals and circuit protection features, such as brown-out reset, watchdog timer, prescalers, clock speed pre-scalers and many more. A variety of external communications interfaces are also available, including USART, SPI, I2C, and a host of other digital and analog communication protocols.

The working principle of the PIC16C74B-04I/P is very simple. It consists of an instruction word, followed by one or more data words (operands) and then an end instruction. All instructions are executed sequentially, and the microcontroller manipulates the operands, making decisions on the fly, according to the instructions. It can be applied to a number of different applications, including embedded, automotive, industrial, and consumer applications. The PIC16C74B-04I/P provides the flexibility of programmable I/O, Programmable Timers/Counters and various other peripherals, while providing a low-power, small package footprint to address embedded requirements in many applications.
