The DS1743W-150+ is a Y2K-compliant, nonvolatile timekeeping RAM from Analog Devices / Maxim Integrated. It integrates NV SRAM, a Real-Time Clock, crystal, power-fail control circuit, and a lithium energy source.
This device features 8 KB of NV SRAM and a Clock/Calendar function, accessed identically to the static RAM. It provides totally nonvolatile operation for over 10 years in the absence of power. The clock registers are BCD-coded and include century, year, month, date, day, hours, minutes, and seconds, with automatic leap year compensation valid through 2099. It also includes a low-battery-voltage level indicator flag and power-fail write protection, allowing for ±10% VCC power-supply tolerance.
The DS1743W-150+ is available in a 28-pin EDIP module package suitable for through-hole mounting. The lithium energy source is electrically disconnected to retain freshness until power is applied for the first time. It is UL recognized to prevent charging of the internal lithium battery.
The DS1743W-150+ has a memory size of 8 KB.
The operating voltage for the DS1743W-150+ is 5V.
The DS1743W-150+ is available in a 28-EDIP Module package.
The RoHS status of the DS1743W-150+ is RoHS3 Compliant.
