Product Usage
The DS1210N is a non-volatile (NV) RAM controller chip by Dallas Semiconductor (now part of Maxim Integrated), used to protect the data in SRAM (Static RAM) during power failures by switching to a battery backup. Here are some typical circuits and applications where DS1210N is used:
Battery-Backed SRAM Modules: The DS1210N is commonly used in memory modules where data retention is crucial, such as in industrial control systems, data logging devices, and equipment that may experience intermittent power loss.
Microcontroller Systems with SRAM: It can be used in conjunction with microcontrollers that use external SRAM for data storage, ensuring that critical data is not lost during power outages.
Embedded Systems: Often found in embedded systems that need to save state or log data periodically, including medical devices, security systems, and telecommunications equipment.
Real-Time Clocks (RTC): Although primarily used for SRAM, the DS1210N can also be a part of RTC circuitry where it ensures the timekeeping device maintains the correct time across power cycles.
Uninterruptible Power Supplies (UPS): In UPS systems, the DS1210N can be used to maintain configuration data or logs.
Power Monitoring: The DS1210N monitors the power supply and when it detects that the main power drops below a certain threshold, it switches to the backup battery to preserve the SRAM data.
Write Protection: During the power-down cycle, it protects the memory content by inhibiting writes to the SRAM until stable power is restored.
In a typical circuit, the DS1210N would be connected between the power supply and the SRAM as follows:
