Due to the benefits of saving space, it is available in the 28-SOIC (0.295, 7.50mm Width) package. In this case, it is mounted using the method of Surface Mount. A package of Tube contains it. PIC core processor is present on the device. When working, it is recommended that the temperature be kept at 0°C~70°C TA. OTP is its program memory type. The device has 22 I/Os. To find comparable components, use the PIC16C66 base part number. A DUAL position is assigned to its terminals. 28 terminationals are present. There are a number of electrical components in the PIC? 16C series, including this one. It is possible to achieve high efficiency with a 5V supply voltage. It has uPs/uCs/Peripheral IC - MICROCONTROLLER, RISC. It is constructed using 28 pins. There are a total of 28 pins on it. This is a component included in Microcontrollers. The devices have a maximum memory size of 14kB that can be used to store programs and data. 20mA is the maximum supply current. A 5V source of power is being used to run it. At a frequency of 20MHz, it exhibits excellent efficiency. While deploying 5V, designers will be able to fully take advantage of its adaptability. 3 timers/counters are in use. It is part of the PIC CPU family. It works with an oscillator type External.
