概要

Description

The AT45DB161E-SHF2B-T is a 16-megabit serial peripheral interface (SPI) flash memory chip produced by Microchip Technology. It features a 3.3V power supply and is designed for high-speed performance with a maximum clock frequency of 66 MHz. The device supports multiple read modes, including continuous read and dual I/O, making it suitable for applications that require quick data access.
With a density of 16 Mbit, it provides ample storage for firmware, configuration data, and user data in embedded systems. The chip has a page erase feature that allows for efficient data management, along with a fast programming capability of around 1.5 ms per page.
The AT45DB161E is ideal for applications in consumer electronics, automotive, and industrial sectors where reliable non-volatile memory is essential. It comes in a compact 8-pin SOIC package, facilitating easy integration into various electronic designs.

Features

The AT45DB161E-SHF2B-T is a 16-megabit (2 M x 8) serial NOR Flash memory, featuring a single I/O interface. It operates on a supply voltage of 2.7V to 3.6V and is designed for low power consumption, making it suitable for battery-operated applications. Key features include:
- Serial Peripheral Interface (SPI) for easy integration with microcontrollers.
- Fast programming and erase times, with a page program time of approximately 10 μs.
- Memory organization in pages (typically 256 bytes) and sectors (typically 64KB) allowing flexible memory management.
- Data retention up to 20 years and endurance for up to 100,000 write/erase cycles.
- Deep power-down mode for extended battery life.
- High-speed clock frequency support (up to 66 MHz).
This memory chip is ideal for data logging, firmware storage, and general-purpose applications requiring non-volatile data retention.

Package

The AT45DB161E-SHF2B-T is packaged in a 16-lead SOIC (Small Outline Integrated Circuit) form factor. This package type is designed for surface mounting and typically features a width of 3.9 mm and a length of 10.3 mm.

Pinout
