Designers seeking innovative design are turning to the pic and AVR microcontroller series of microchip. These new products have powerful processing power, can easily communicate with other chips and analog peripherals, and can realize super configuration without changing the printed circuit board (PCB) during construction. These devices combine ASIC like functions with simple development experience, expand the functions of traditional MCU, and allow them to be configured as intelligent peripheral chips. Intelligent peripherals such as software controlled operational amplifier, multi voltage input / output (mvio) and analog-to-digital converter (ADCC) with computing function in pic16f171 series bring new value to applications that do not use traditional MCU.


Systems using different power supply voltage chips often need to span multiple voltage domains (for example, connect a 5V MCU to a 1.8V sensor). Such systems usually require level conversion hardware, which increases the cost. Mvio peripherals in microchip's latest 8-bit MCU (including AVR DD Series) allow a single port on the MCU to work in a voltage domain different from other parts of the MCU, thus eliminating the need for additional external components.

Some systems require a certain level of speed and response time, which is difficult for software based processing. MPLAB can be used for kernel independent peripherals (CIPS) of Microchip PIC and AVR product families ® The code configurator (MCC) is programmed to facilitate the connection to form a hardware processing chain. This makes it possible to create custom peripherals, thereby eliminating the cycle time of software processing. For example, by configuring a super peripheral composed of pulse width modulator (PWM), SPI interface and configurable logic unit (CLC), it is easy to control a ws2812 LED array that requires a unique timing to drive correctly.

With the continuous growth of the 8-bit pic and AVR MCU device market, microchip continues to respond to customers' long-term needs by adhering to the powerful basic functions in its product portfolio and support structure. Pic and AVR MCU are very easy to design, and their support network enables microchip customers to shorten the time to realize revenue. The 8-bit MCU product portfolio is pin to pin compatible. When higher performance is required or customers want to maximize product supply and minimize redesign requirements, alternative pic or AVR MCU can be selected.

Greg Robinson, vice president of marketing of microchip 8-bit MCU business department, said: "pic and AVR MCU are very popular. Their design can meet the requirements of our customers for current and future applications. We have also established a strong supply chain for 8-bit pic and AVR MCU, most of which are produced in microchip's own factories. This enables us to control the production process in a way that is not common in the industry."
