The newest members of Microchip Technology Inc.'s PIC18F high-end 8-bit microcontroller family are the PIC18F8622/8527/6622/6527 series. They offer an extra serial port for expanded connectivity and a faster analog-to-digital converter (ADC) for quicker measurement, all at a 30 percent lower price than the previous generation.

Through nanoWatt Technology, the sleep current is 40 percent lower, and the operating current is more than 50 percent lower, over previous generations. This combination of cost-effectiveness, features and performance is ideal for a wide variety of applications, such as battery-powered, industrial and consumer products, according to the company.

Design engineers are faced with ever-increasing demands for processing power and connectivity, while simultaneously facing the challenge to lower power consumption and overall system costs. The new series of MCUs provides high performance with its 10bit, 100ksps ADC; extended communication with two synchronous and two asynchronous serial ports; and longer battery life and an 8MHz internal oscillator.

The PIC18F8622 is compatible with Microchip's MPLAB development tools and C-code efficiency. "The PIC18F8622 series completes the migration path for nanoWatt Technology from 48KB to 128KB of Flash in Microchip's popular PIC18F family of high-end 8bit MCUs," said Mitch Obolsky, VP of Microchip's Advanced Microcontroller Architecture Division.

All four members of the PIC18F8622 series are available today for general sampling and volume production. The PIC18F8622 and PIC18F8527 are available in 80-pin TQFP packaging, while the PIC18F6622 and PIC18F6527 are available in 64-pin TQFP packaging. Unit pricing for the PIC18F8622 starts at $5.23 in quantities of 10,000 pieces.
