Description

The 29F400BC-90-V G7 is an IC chip in the electronic components category. It is a 4M-bit, 5.0 V-only Flash memory that can be organized as 512K bytes of 8 bits each, or 256K words of 16 bits each. It is offered in 48-pin TSOP and 44-pin SOP packages. The device is designed to be programmed in-system with the standard system 5.0 V VCC supply. It can also be reprogrammed in standard EPROM programmers. The chip has a single 5.0 V read, write, and erase capacity which minimizes system-level power requirements.

Specifications and Features

• Compatible with JEDEC-standard commands
• Uses same software commands as E2PROMs
• Compatible with JEDEC-standard world-wide pinouts
• Minimum 100,000 write/erase cycles
• High performance- 55 ns maximum access time
• Sector erase architecture- one 16K byte, two 8K bytes, one 32K byte, and seven 64K bytes
• Embedded EraseTM Algorithms -Automatically pre-programs and erases the chip or any sector
• Embedded ProgramTM Algorithms -Automatically writes and verifies data at specified address
• Data Polling and Toggle Bit feature for detection of program or erase cycle completion
• Ready/Busy output (RY/BY)-Hardware method for detection of program or erase cycle completion
• Low Vcc write inhibit ≤ 3.2 V
• Erase Suspend/Resume-Suspends the erase operation to allow a read in another sector within the same device
• Hardware RESET pin-Resets internal state machine to the read mode
• Sector protection- Hardware method disables any combination of sectors from write or erase operations
• Temporary sector unprotection -Temporary sector unprotection via the RESET pin

Application Scenarios

This IC chip can be used in various electronic devices that require a 4M-bit, 5.0 V-only Flash memory. Since it has high performance and a single 5.0 V read, write and erase capacity, it can be integrated into devices with minimal power requirements. It can also be used as a replacement part for devices that have similar characteristics.

Comparison

• High performance with 55 ns maximum access time
• Compatible with JEDEC-standard commands and world-wide pinouts
• Single 5.0 V read, write, and erase capacity which minimizes system-level power requirements
• Can be reprogrammed in standard EPROM programmers

• The device is available only in 48-pin TSOP and 44-pin SOP packages
• Erase Suspend/Resume only allows reads within the same device
• The device does not support 12.0 V VPP; however, it's not required for write or erase operations
