The DS1746-70+ from Dallas Semiconductor is a Y2K-compliant, nonvolatile static RAM (NV SRAM) with an integrated real-time clock (RTC). This component combines NV SRAM, an RTC, a crystal, a power-fail control circuit, and a lithium energy source into a single package.
Key features include over 10 years of nonvolatile operation without external power, automatic leap year compensation valid up to the year 2100, and power-fail write protection with a ±10% VCC power supply tolerance. The clock registers are accessed identically to the static RAM, residing in the eight top RAM locations.
This device is available in a 32-pin EDIP (Extended DIP) package with a through-hole mounting type. It operates over a voltage range of 5V and has an operating temperature range of 0°C to +70°C. The lithium energy source is electrically disconnected to retain freshness until power is applied for the first time.
