Hardware Features
Software Features
Sector Protection
— Software command sector locking
Reduced Wait-State Handshaking feature available
— Provides host system with minimum possible latency
Hardware reset input (RESET#)
— Hardware method to reset the device for reading
WP# input
— Write protect (WP#) function protects sectors 0 and 1
ACC input: Acceleration function reduces
programming time; all sectors locked when ACC =
V
CMOS compatible inputs, CMOS compatible outputs
Low V
Supports Common Flash Memory Interface (CFI)
Software command set compatible with JEDEC
42.4 standards
— Backwards compatible with Am29F and Am29LV
Data# Polling and toggle bits
— Provides a software method of detecting program
Erase Suspend/Resume
— Suspends an erase operation to read data from, or
Unlock Bypass Program command
— Reduces overall programming time when issuing
IL
