Replacing the Maxim DS1337 RTC with the ISL12057
Intersil has recently introduced the ISL12057 Real Time Clock (RTC) devices. The device is pin-to-pin (8 Ld SOIC and 8 Ld MSOP package) and software compatible to Maxim DS1337 RTC. In fact, the ISL12057 is an enhancement because it provides:
• Fixed Default Register Values at Power-up
• Flexible Alarm Selection
• Stable Frequency Output vs V-DD
• Smaller Package Option - 2mmx2mm μTDFN (Tiniest RTC available in the market)
The features are detailed in the data sheets. This Technical Brief provides information for an engineer wishing to use the ISL12057 to replace the DS1337 in their system.
