Rochester Electronics Memory DS1350WP-150

The DS1350WP-150 is a nonvolatile SRAM memory device with a capacity of 1,048,576 bits, organized as 131,072 words by 8 bits. It features a built-in lithium energy source that ensures data retention for a minimum of 10 years without external power. The device automatically protects data during power loss and includes a power supply monitor that resets the processor when voltage drops below a certain threshold. It also has a battery monitor that checks the remaining capacity daily. This memory operates at a supply voltage of 3.3V and offers read and write access times of 100 ns, with unlimited write cycle endurance. The typical standby current is 50 ¬µA. The DS1350WP-150 is designed for surface mounting and is compatible with a replaceable PowerCap module, which provides the lithium backup battery. It is available in an industrial temperature range of -40¬8C to +85¬8C, making it suitable for a variety of applications. The device is a potential upgrade for existing SRAM, EEPROM, or Flash components.
