DS1543 - 64k NV Timekeeping RAM

Description

A0-A12 - Address Input DQ0-DQ7 - Data Input/Outputs IRQ FT - Interrupt, Frequency Test Output (Open-Drain) RST - Power-On Reset Output (Open-Drain) CE - Chip Enable OE - Output Enable WE VCC GND NC - Write Enable - Power Supply Input - Ground - No Connection 1 of 17 081000 DS1543 DESCRI

Features

  • Integrated NV SRAM, real time clock, crystal, power-fail control circuit and lithium energy source Clock registers are accessed identical to the static RAM. These registers are resident in the sixteen top RAM locations Totally nonvolatile with over 10 years of operation in the absence of power Precision Power-On Reset Programmable Watchdog Timer and RTC Alarm BCD coded year, month, date, day, hours, minutes, and seconds with automatic leap year compensation valid up to the year 2100 Battery volt.
