DS1230Y-85

Product Overview

Category

The DS1230Y-85 belongs to the category of non-volatile static RAM (NVSRAM).

Use

It is primarily used for storing data that needs to be retained even when power is lost.

Characteristics

• Non-volatile: Data remains intact even without power.
• Static RAM: Provides fast read and write access times.
• Low power consumption: Operates at low power levels.
• High reliability: Offers robust data retention and endurance.

Package

The DS1230Y-85 is available in a 28-pin DIP (Dual Inline Package) format.

Essence

The essence of the DS1230Y-85 lies in its ability to combine the benefits of both SRAM and non-volatile memory technologies.

Packaging/Quantity

The DS1230Y-85 is typically packaged individually and sold as a single unit.

Specifications

• Memory capacity: 32 kilobits (4 kilobytes)
• Access time: 85 nanoseconds
• Supply voltage: 4.5V to 5.5V
• Operating temperature range: -40°C to +85°C
• Data retention: Minimum 10 years

Detailed Pin Configuration

The DS1230Y-85 has a total of 28 pins, each serving a specific function. The detailed pin configuration is as follows:

1. Chip Enable (CE)
2. Output Enable (OE)
3. Write Enable (WE)
4. Address Inputs (A0-A14)
5. Data Inputs/Outputs (DQ0-DQ7)
6. Ground (GND)
7. VCC (+5V)

Functional Features

• Battery backup: The DS1230Y-85 can be connected to an external battery to ensure data retention during power loss.
• Automatic store on power loss: It automatically saves the data to non-volatile memory when power is lost.
• High-speed access: Provides fast read and write access times for efficient data handling.

Advantages and Disadvantages

Advantages

• Non-volatile storage: Data remains intact even without power.
• Fast access times: Allows for quick retrieval and modification of stored data.
• Low power consumption: Operates at low power levels, extending battery life in portable applications.

Disadvantages

• Limited storage capacity: The DS1230Y-85 has a relatively small memory capacity compared to other storage devices.
• Higher cost: NVSRAM technology tends to be more expensive than traditional SRAM or DRAM.

Working Principles

The DS1230Y-85 combines the benefits of SRAM and non-volatile memory technologies. It utilizes a small battery to provide backup power, ensuring that data remains intact during power loss. When power is restored, the DS1230Y-85 automatically transfers the data from the SRAM to the non-volatile memory, preserving it for future use.

Detailed Application Field Plans

The DS1230Y-85 finds applications in various fields, including:

1. Industrial control systems: Used for storing critical configuration data and program code.
2. Embedded systems: Provides non-volatile storage for system parameters and settings.
3. Automotive electronics: Stores essential data such as mileage, engine diagnostics, and user preferences.
4. Medical devices: Utilized for storing patient information, device settings, and calibration data.

Detailed and Complete Alternative Models

Some alternative models to the DS1230Y-85 include:

1. DS1230AB-120: Offers a higher access time of 120 nanoseconds.
2. DS1230AB-200: Provides a lower access time of 200 nanoseconds.
3. DS1230AB-70: Features a faster access time of 70 nanoseconds.
