PIC16C74B-20/L Description

Short technical summary and product information.

The Microchip PIC16C74B-20/L is an 8-bit microcontroller based on the PIC architecture, operating at a maximum frequency of 20MHz. It provides 7KB of One-Time Programmable (OTP) memory for program storage and 192 bytes of RAM for data. This device is designed for embedded applications requiring a moderate number of I/O pins, offering 33 general-purpose I/O lines.

Key features include an integrated 8-bit Analog-to-Digital converter with 8 channels, supporting various analog input requirements. The microcontroller also includes peripherals such as Timer0, Timer1, Timer2, Capture/Compare/PWM modules, a Synchronous Serial Port (SSP) supporting SPI and I2C protocols, and a Universal Synchronous Asynchronous Receiver Transmitter (USART/SCI). It also features Brown-out Detect/Reset, Power-on Reset (POR), and a Watchdog Timer (WDT).

The PIC16C74B-20/L operates within a voltage range of 4V to 5.5V and has an operating temperature range of 0°C to 70°C (TA). It is supplied in a 44-PLCC (16.59x16.59) package, designed for surface mounting. The package is also referred to as 44-LCC (J-Lead).
