Description

The 29F400TC-70 is a 4M-bit Flash memory electronic component, belonging to the IC Chips product category. It is designed to be programmed in-system and does not require 12.0 V VPP supply for write or erase operations. It is offered in 48-pin TSOP and 44-pin SOP packages.

Specifications and features

• Single 5.0 V read, write, and erase
• Compatible with JEDEC-standard commands, software commands as E2PROMs, and 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. Any combination of sectors can be concurrently erased. Supports full chip erase
• Boot Code Sector Architecture: T = Top sector, B = Bottom sector
• 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 electronic component is suitable for use in flash memory applications where high performance, low power consumption, and minimal system requirements are critical. It can be used for personal computers, mobile phones, automotive systems, digital cameras, and other similar devices.
