ACCURACy

Tiny Real Time Clock (RTC) module with

embedded crystal and temperature

compensation circuitry achieves better than

±5 ppm accuracy over the entire industrial

temperature range (-40°C to +85°C). Intersil

is the first to offer an RTC module in a DFN

package. This makes this module very attractive

for handheld and portable applications that have

stringent space requirements.
