概述

Description

The AT45DB161E-SSHF-T is a 16-megabit (2M x 8 bits) serial flash memory chip manufactured by Atmel (now part of Microchip Technology). It utilizes the SPI (Serial Peripheral Interface) protocol, allowing for high-speed data transfer rates. This chip features a uniform sector architecture, with each sector consisting of 4KB, which supports flexible data management and efficient erasing and programming operations.
Key features include:
1. Voltage Range: Operates at 2.7V to 3.6V, making it suitable for low-power applications.
2. High Performance: Fast read speeds of up to 85 MHz and quick programming times enhance system responsiveness.
3. Data Security: Supports over 100,000 program/erase cycles, with data retention of over 20 years.
4. Small Form Factor: Available in a compact 8-pin SOIC package, ideal for space-constrained designs.
The AT45DB161E-SSHF-T is commonly used in applications like consumer electronics, automotive systems, and industrial controls, where reliable non-volatile storage is essential.

Features

The AT45DB161E-SSHF-T is a 16 megabit (2 Megabyte) serial flash memory chip designed by Atmel (now part of Microchip Technology). Key features include:
1. Interface: SPI (Serial Peripheral Interface) for easy integration with microcontrollers.
2. Memory Organization: It is organized in 8 sectors of 4KB each and 32 pages of 256 bytes, allowing efficient data storage and retrieval.
3. Data Retention: Typically provides excellent data retention of up to 20 years.
4. Erase and Program: Supports fast page programming and full chip erase capabilities, with a maximum page program time of 12ms.
5. Low Power Consumption: Designed for low power operation, making it suitable for battery-operated devices.
6. High Speed: Offers high-speed read operations (up to 85 MHz).
7. Package: Available in a small, space-saving 8-lead SOIC package.
This device is ideal for applications requiring non-volatile storage, such as firmware storage, data logging, and configuration settings in embedded systems.
