Description

The DS9034PC+ is a full-function, year-2000-compliant (Y2KC), real-time clock/calendar (RTC) and 8k x 8 non-volatile static RAM, belonging to the product category of Memory - Batteries.

Specifications and features

• Integrated NV SRAM, real-time clock, crystal, power-fail control circuit, and Lithium energy source
• Clock registers are accessed identically to the static RAM. These registers reside in the eight top RAM locations.
• Century byte register and totally non-volatile with over ten years of operation in the absence of power
• BCD-coded century, year, month, date, day, hours, minutes, and seconds with automatic leap year compensation valid through 2099
• Low-battery-voltage-level indicator flag and power-failure write protection allows for ±10% VCC power-supply tolerance
• Lithium energy source is electrically disconnected to retain freshness until power is applied for the first time
• DIP module only with standard JEDEC Bytewide 8k x 8 Static RAM Pinout and PowerCap module board only for surface-mountable package for direct connection to PowerCap containing battery and crystal
• Replaceable battery (PowerCap), power-on reset output, and pin-for-pin compatible with other densities of DS174XP Timekeeping RAM
• Underwriters Laboratories (UL) recognized to prevent charging of the internal lithium battery

Application Scenarios

The DS9034PC+ can be used in a variety of applications, such as electronic devices, communication devices, medical instrumentation, security systems, and more.

Comparison

• Year-2000-compliant and provides automatic leap year compensation through 2099
• Integrated NV SRAM, real-time clock, crystal, power-fail control circuit, and Lithium energy source
• Totally non-volatile with over ten years of operation in the absence of power
• Lithium energy source is electrically disconnected to retain freshness until power is applied for the first time
• Underwriters Laboratories (UL) recognized to prevent charging of the internal lithium battery

• The PowerCap module board is only surface-mountable and requires direct connection to PowerCap containing battery and crystal
• DIP module only and pin-for-pin compatible with other densities of DS174XP Timekeeping RAM, which may limit the flexibility of the device
