The DS1248WP-120 is a 128K NV SRAM with a phantom clock, designed by Analog Devices Inc. (formerly Maxim Integrated). This integrated circuit functions as a Real Time Clock (RTC) and includes 128K x 8 bits of non-volatile static RAM, directly replacing volatile static RAM or EEPROM. It features an embedded lithium energy cell that maintains calendar operation and retains RAM data, even in the absence of power, offering over 10 years of data retention.
The device operates with a supply voltage of 3V and a typical current draw of 7mA at 3.3V. It supports a parallel interface and is suitable for operation within a temperature range of 0°C to 70°C. The RTC keeps track of seconds, minutes, hours, days, date, months, and years, with automatic leap year compensation valid up to 2100.
Packaged in a 34-PowerCap Module, the DS1248WP-120 is designed for surface mounting. This configuration allows for direct connection to a separate PowerCap containing the battery and crystal, offering a replaceable battery solution. The part is pin-for-pin compatible with DS1244P and DS1251P.
The operating voltage for the DS1248WP-120 is 3V, with a supply range of 2.97V to 3.63V.
The DS1248WP-120 operates within a temperature range of 0°C to 70°C.
