Description and Introduction

3.3 and 5.0 volt micromonitor The DS1705 is a real-time clock (RTC) and nonvolatile RAM (NV RAM) device manufactured by Maxim Integrated (formerly Dallas Semiconductor). Below are its key specifications:

1. **Features**:
   - Integrated real-time clock (RTC) with battery backup.
   - 32.768 kHz crystal oscillator.
   - Nonvolatile static RAM (NV SRAM) – 16KB (DS1705-16) or 64KB (DS1705-64).
   - Automatic power-fail detection and switchover to battery backup.
   - Battery-backed timekeeping and RAM retention.
   - Century byte register for year 2000 compliance.

2. **Timekeeping**:
   - Tracks seconds, minutes, hours, day, date, month, and year (with leap-year compensation).
   - 24-hour or 12-hour (AM/PM) format.
   - Binary or BCD time representation.

3. **Power Supply**:
   - Operates from 4.5V to 5.5V (primary supply).
   - Battery backup voltage range: 2.0V to 3.5V.
   - Low power consumption in battery mode.

4. **Memory**:
   - 16KB or 64KB of NV SRAM (depending on model).
   - Unlimited read/write cycles.
   - Data retention for over 10 years without power.

5. **Interface**:
   - Parallel interface compatible with standard SRAM.
   - Directly interfaces with microprocessors.

6. **Package Options**:
   - Available in 32-pin DIP and 32-pin SOIC packages.

7. **Operating Temperature**:
   - Commercial range: 0°C to +70°C.
   - Industrial range: -40°C to +85°C.

8. **Applications**:
   - Embedded systems requiring timekeeping and nonvolatile memory.
   - Data loggers, industrial controls, and medical devices.
