Accurate MEMS Real-Time Clocks Product Guide
Benefits of MEMS Technology in RTC Applications
Environmental and Manufacturing Ruggedness
Maxim Integrated’s MEMS-based RTC products have proven, demonstrable performance advantages based on environmental
criteria and observation. In reflow operations that replicate customer attachment, MEMS devices demonstrate frequency shifts
of less than ±1ppm (Figures 1a and 1b). Crystal-based products that face the same regimen of reflow temperature exposure
demonstrate shifts as high as ±5ppm. One of the most important criteria for establishing how well a device operates is its
frequency performance prior to attachment to a motherboard compared to its performance after this attachment process. The
attachment process can have temperature excursions as high as +260°C for several seconds and be above +200°C for several
10s of seconds. Dependable frequency performance over the life of the device is the most important criteria for choosing accurate
timekeeping products. Maxim Integrated MEMS RTCs guarantee ±5ppm frequency accuracy and stability regardless of voltage,
time (aging), or temperature.
Additionally, MEMS-based RTCs have demonstrable shock and vibration performance and have passed AEC-Q100 qualification,
making them one of the most rugged, dependable, and accurate solutions in the industry.
Benefits
• Higher manufacturing temperature processes (+260°C reflows, < 1ppm frequency shifts, fully RoHS)
• Significantly higher shock and vibration capability (> 50g)
• Wide operational temperature environments (-40°C to +85°C)
