DS1747P-70+ Description

Short technical summary and product information.

The DS1747P-70+ by Dallas Semiconductor is a Y2K-compliant, nonvolatile timekeeping RAM. This integrated circuit combines NV SRAM, a Real-Time Clock (RTC), a crystal, a power-fail control circuit, and a lithium energy source.

 

The device features 512KB of memory and a parallel interface. It operates within a voltage supply range of 4.5V to 5.5V and has a battery voltage of 3V. The operating temperature range is 0°C to 70°C. The timekeeping current consumption is a maximum of 4mA at 5V.

 

Key features include automatic leap year compensation valid up to the year 2100, a battery voltage-level indicator flag, and power-fail write protection with ±10% VCC power-supply tolerance. The clock registers are accessed identically to the static RAM, residing in the eight top RAM locations.

 

This component is available in a 34-PowerCap™ Module package and is designed for surface mounting. It offers over 10 years of operation in the absence of power, ensuring data integrity and reliable timekeeping.
