The AM29DL400BB-70EC is a 4 Mbit (512 K x 8-bit / 256 K x 16-bit) CMOS 3.0 Volt-only, simultaneous operation Flash memory device manufactured by Advanced Micro Devices (AMD). It offers separate data I/O pins for reading data and writing data, which allow simultaneous read/write operations.

Applications

• Wireless communication devices (e.g., cellular phones, pagers).
• Networking equipment (e.g., routers, switches).
• Embedded systems for storing code and data.
• Digital cameras and other portable devices.
• Automotive applications (e.g., engine control units).

Features

• 4 Mbit (512 K x 8-bit / 256 K x 16-bit) CMOS Flash Memory
• Simultaneous Read/Write Operations
• 3.0 Volt-only operation for read and write
• 70 ns access time
• Sector Erase Architecture: Uniform 64 Kbyte sectors
• Erase Suspend/Resume: Supports interrupting erase operations to read data from other sectors
• Embedded Erase and Program Algorithms
• Automatic Program Timing
• JEDEC standard pinout
• Available in a TSOP package

Benefits

• Simultaneous operation enables faster system performance by allowing read and write operations to occur concurrently.
• Low voltage operation reduces power consumption, extending battery life in portable applications.
• Fast access time allows for quick boot-up and execution of embedded code.
• Sector erase architecture allows for flexible memory management and efficient data updates.
• Erase Suspend/Resume feature ensures that critical data can be accessed even during erase operations.
• Embedded algorithms simplify memory programming and reduce system overhead.
• Standard JEDEC pinout allows for easy integration into existing systems.

Additional Details

The AM29DL400BB-70EC operates from a single 3.0V power supply and is available in a TSOP package. The simultaneous operation feature is particularly useful in applications where data needs to be updated frequently while also providing read access to the stored data. The device features embedded erase and program algorithms which further simplifies memory programming.
