The DS1558W is a Real Time Clock (RTC) IC manufactured by Analog Devices, also known as Maxim Integrated. This component integrates a real-time clock, a power-fail control circuit, and an NV RAM controller. The clock registers are accessed identically to static RAM and reside in the top 16 RAM locations.
Key features include a century register, over 10 years of timekeeping and data retention without power (with a small lithium coin cell and low-leakage SRAM), precision power-on reset, and a programmable alarm. It supports BCD-coded year, month, date, day, hours, minutes, and seconds with automatic leap-year compensation valid up to the year 2100. A battery voltage-level indicator flag and power-fail write protection are also included, allowing for ±10% VCC power-supply tolerance.
The DS1558W operates with a voltage range of 2.5V to 3.7V and consumes approximately 2mA at 3.3V. It supports a parallel interface for accessing its functions. The device is designed for surface mounting and comes in a 48-LQFP (7x7mm) package.
The DS1558W features an integrated Real-Time Clock (RTC), Power-Fail Control Circuit, NV RAM Controller, Century Register, programmable alarm, and watchdog timer. It also offers over 10 years of timekeeping and data retention without power.
The DS1558W operates with a voltage range of 2.5V to 3.7V.
