The DS1742-100+ is an integrated circuit (IC) component manufactured by Maxim Integrated. It is a non-volatile static RAM (NVSRAM) specifically designed for timekeeping and data storage applications. With its small form factor and low power consumption, this IC is widely used in various electronic devices.
One of the key features of the DS1742-100+ is its non-volatile memory, which means that it retains data even when the power supply is disconnected. This is achieved by incorporating an on-chip lithium energy source that powers the IC in the absence of an external power supply. The non-volatile feature makes it highly suitable for applications where data retention and reliability are crucial.
Another noteworthy feature is its static RAM component, which provides fast and random access to the stored data. With a 4-wire interface, the DS1742-100+ offers convenient read and write operations, allowing users to efficiently retrieve and update the stored information.
Furthermore, the DS1742-100+ has a power sense circuit that detects power failures and automatically switches to the on-chip lithium energy source to maintain accurate timekeeping and data retention. The power sense circuit also serves as a power-fail chip-enable (CE) control, enabling a smooth transition between external and internal power supplies.
The DS1742-100+ operates in a wide voltage range, from 2.7V to 5.5V, providing flexibility and compatibility with various power sources
