The DS1251Y-70 from Analog Devices / Maxim Integrated is a 4096K (512K x 8 bit) Non-Volatile Static RAM (NV SRAM) with an integrated real-time clock. This component is designed to directly replace volatile static RAM or EEPROM, offering the advantage of embedded lithium energy cell to maintain calendar operation and retain RAM data.
Key features include automatic leap year compensation valid up to the year 2100 and over 10 years of data retention in the absence of power. The watch function is transparent to RAM operation. The device operates over a voltage range of 4.5V to 5.5V with a typical current consumption of 10mA at 5V.
This part is available in a 32-pin EDIP package suitable for through-hole mounting. It supports a parallel interface and operates within a temperature range of 0°C to 70°C. The DS1251Y-70 is designed for applications requiring continuous timekeeping and data storage without external power.
It is recognized by Underwriters Laboratories (UL). The module is designed for ease of integration, offering a standard 32-pin JEDEC pinout and is upward compatible with the DS1248.
The DS1251Y-70 has a memory size of 512Kb.
The DS1251Y-70 is a Phantom Time Chip.
Key features include Leap Year compensation and NVSRAM.
The operating voltage range is 4.5V to 5.5V.
The operating temperature range is 0°C to 70°C.
The typical current consumption is 10mA at 5V.
The DS1251Y-70 can retain data for over 10 years in the absence of power.
