Microchip Technology Inc. has announced the four-member PIC18F4523 family, the company's first high-end 8bit flash MCUs to include a high-speed 12bit ADC peripheral on-chip. Additionally, this MCU includes nanoWatt Technology features, which provide multiple options for effectively managing power consumption and extending battery life. These features eliminate the cost and complexity of interfacing to an external ADC, the company said, while providing the precision required for high-speed, high-resolution sensor measurements in applications such as medical, industrial and utility metering.

Sophisticated embedded systems increasingly require advanced sensor measurement with very low power consumption and very little board space. By providing an 8bit MCU with a 12bit, 13-channel ADC and advanced power management in small 28-, 40- and 44-pin packages, Microchip said its PIC18F4523 family is meeting these market needs.

"The addition of 12bit ADCs to the PIC18 portfolio offers system designers the ability to employ advanced sensor designs that were previously out of reach without the use of external components," said Mitch Obolsky, VP of Microchip's advanced microcontroller architecture division. "This saves on overall component costs but, more importantly, the effort involved in implementing complex designs."

The PIC18F4523 family is suited for a broad range of applications requiring precision measurement and control. It also maintains compatibility with Microchip's free MPLAB IDE integrated development environment, MPLAB C18 C compiler, MPLAB ICD 2 in-circuit debugger and emulator, and the MPLAB PM3 universal device programmer. In addition, the PICDEM 2 Plus (part # DM163022) demonstrates the capabilities of the PIC18F4523 family.

The PIC18F4523/4423/2523/2423 MCUs are available for general sampling and volume-production shipments. The PIC18F4523/4423 come in 44-pin QFN or TQFP and 40-pin PDIP packages, while the PIC182523/2423 are available in 28-pin QFN, SOIC and SPDIP packages, all of which are RoHS-compliant.
