概述

Description

The M48T08-150PC1 is a battery-backed static RAM (SRAM) memory chip that combines the functionality of a SRAM with the convenience of non-volatile storage. It is designed to retain data even during power outages, thanks to an integrated lithium battery that provides power to retain memory contents when the main power is lost.
This specific model features 1 megabit (128K x 8 bits) of storage capacity and operates at a maximum access time of 150 nanoseconds, making it suitable for applications that require quick data retrieval. The device is packaged in a 28-pin DIP (Dual In-line Package), facilitating easy integration into various electronic systems.
The M48T08-150PC1 is often used in applications such as telecommunications, industrial automation, and embedded systems, where reliable data retention is crucial. Its ability to automatically switch to battery mode when external power is lost ensures that critical data is not lost, making it a popular choice for designers seeking robust memory solutions.

Features

The M48T08-150PC1 is a Real-Time Clock (RTC) with a built-in battery backup and non-volatile SRAM. Key features include:
1. Memory Capacity: 8K x 8 bits of SRAM, retaining data during power loss.
2. Real-Time Clock: Maintains accurate time and date, supports leap years.
3. Battery Backup: Integrated battery allows continued operation and timekeeping during power interruptions.
4. Interface: Uses a standard parallel interface for easy integration with microcontrollers.
5. Low Power Consumption: Designed for energy efficiency, extending battery life.
6. Temperature Range: Operates within a wide temperature range, suitable for various environments.
7. Power Supply Voltage: Typically operates at 5V, with a maximum of 6V.
8. Package Type: Available in a 28-pin DIP or other configurations for versatile mounting options.
This device is ideal for applications requiring timekeeping and data retention, such as in consumer electronics, industrial systems, and embedded applications.
