概要

Description

AT25DN512C-SSHF-T is a 512‑Mbit serial SPI flash memory from Atmel (Microchip) used for non-volatile storage in embedded systems. Key points:
- Capacity: 512 Mb (64 MB)
- Interface: Serial SPI flash with standard Read/Write/Erase commands (high-speed reads available)
- Voltage: 1.8–3.6 V supply
- Speed: Fast read options up to about 100 MHz
- Organization: Pages (up to 256 bytes), sectors (e.g., 4 KB), blocks (e.g., 64 KB)
- Erase/Program: Sector and block erases plus page programming; chip erase if needed
- Endurance and retention: Typical sector P/E cycles on the order of 100k; data retention ~20 years
- Security/protection: Write protection and status/lock bits for memory regions
- Power management: Power-down and wake-up modes
- Package: 8-pin device in SSHF form factor; suffix “T” indicates Tape & Reel shipping
Ideal for boot code, firmware storage, and data logging in embedded applications. For exact command set, timing, and electrical specs, consult the AT25DN512C data sheet.

Features

AT25DN512C-SSHF-T features (concise):
- Density: 512 Mbit (64 MB) serial DataFlash
- Interface: SPI-compatible serial interface with support for dual/quad I/O modes
- Read/Write: Random byte access; page program; sector/block erase
- Organization: Page size and sector/block sizes per datasheet (optimized for embedded code/data storage)
- Performance modes: Fast read and continuous read options
- Power: Deep power-down and low-power standby modes
- Reliability/security: Hardware write protection, block protection registers, and security features
- Protection: WP# and BPx pins for data protection
- Packaging/conditions: 8-pin SSHF package; RoHS-compliant; industrial temperature range (typical)
- Voltage: Broad supply range (typical 2.7V–3.6V)
Note: For exact page/sector sizes, erase blocks, throughput numbers, and operating conditions, please refer to the AT25DN512C datasheet for this specific variant.

Package

8‑pin SSOP (Small‑Outline, 8‑lead) package, Halogen‑Free (HF). The -T suffix indicates Tape & Reel packaging.

Pinout

- Pin count: 8 pins (8‑pin package, e.g., SOIC-8)
- Function: 512 Mbit serial SPI flash memory (non-volatile storage) used for program/data storage. It provides a standard SPI interface (CS, CLK, DI, DO) plus WP# and HOLD# control signals. Some variants support dual/quad I/O SPI modes.

Manufacturer

- Manufacturer: Microchip Technology Inc. (the company that now owns Atmel’s product line; AT25DN512C-SSHF-T was an Atmel DataFlash part before the Atmel acquisition).
- What kind of company: A multinational semiconductor company (an integrated device manufacturer, designing and manufacturing microcontrollers, memory products and other ICs).

Application

Common uses for AT25DN512C-SSHF-T include:
- Boot flash and firmware storage for microcontrollers/SoCs
- High-density code/data storage for consumer electronics, IoT, and networking gear
- Firmware update and secure storage with block protection
- Data logging and configuration storage in industrial/automotive systems
- Harsh-environment applications (wide temperature range) requiring reliable external flash
