Maxim Integrated DS1345YP-70 Nonvolatile Timekeeping RAM

The DS1345YP-70 is a cutting-edge nonvolatile timekeeping RAM product designed and manufactured by Maxim Integrated, a renowned leader in the development of innovative mixed-signal products for the industrial, communications, consumer, and computing markets. This high-performance integrated circuit combines a full-featured real-time clock/calendar and 1024k x 8 nonvolatile static RAM.

Key Features

• Real-Time Clock/Calendar: The DS1345YP-70 features a highly accurate real-time clock/calendar that provides seconds, minutes, hours, day, date, month, and year information. The end of the month date is automatically adjusted for months with fewer than 31 days, including corrections for leap year.
• Nonvolatile Memory: It includes 1024k x 8 bits of nonvolatile static RAM, which ensures data retention without the need for a battery backup during power loss.
• Integrated Battery Input: The device comes with a direct battery input which maintains timekeeping and RAM data with a nominal timekeeping voltage as low as 2.5V.
• Low Power Operation: Designed for low power consumption, the DS1345YP-70 extends the life of the battery backup source, making it ideal for battery-powered applications.
• Industrial Temperature Range: This product operates reliably across an industrial temperature range of -40°C to +85°C, catering to the stringent requirements of industrial environments.
• Surface-Mount Package: The device is available in a 28-pin 600-mil surface-mount package, which is suitable for high-density mounting and is compatible with standard PCB assembly processes.

Applications

The DS1345YP-70 is particularly well-suited for applications where durable and reliable nonvolatile memory is critical. These include utility meters, HVAC systems, audio/video components, POS terminals, and medical devices. Its robust design ensures that critical data is preserved and timekeeping functions are maintained even in the event of a power interruption.
