Distinctive Characteristics
Architectural Advantages
? Single Power Supply Operation
– Full voltage range: 2.7 to 3.6 volt read and write operations for
battery-powered applications
? Manufactured on 110 nm Process Technology
– Fully compatible with 200 nm S29AL008D
? Secured Silicon Sector region
– 128-word/256-byte sector for permanent, secure identification
through an 8-word/16-byte random Electronic Serial Number
accessible through a command sequence
– May be programmed and locked at the factory or by the customer
? Flexible Sector Architecture
– One 16 Kbyte, two 8 Kbyte, one 32 Kbyte, and fifteen 64 Kbyte
sectors (byte mode)
– One 8 Kword, two 4 Kword, one 16 Kword, and fifteen 32 Kword
sectors (word mode)
? Sector Group Protection Features
– A hardware method of locking a sector to prevent any program or
erase operations within that sector
– Sectors can be locked in-system or via programming equipment
– Temporary Sector Unprotect feature allows code changes in
previously locked sectors
? Unlock B** Program Command
– Reduces overall programming time when issuing multiple program
command sequences
? Top or Bottom Boot Block Configurations Available

Package Options
? 48-ball Fine-pitch BGA
? 48-pin TSOP
Software Features
? CFI (Common Flash Interface) Compliant
– Provides device-specific information to the system, allowing host
software to easily reconfigure for different Flash devices
? Erase Suspend/Erase Resume
– Suspends an erase operation to read data from, or program data to,
a sector that is not being erased, then resumes the erase operation
? Data# Polling and Toggle Bits
– Provides a software method of detecting program or erase operation
completion
Hardware Features
? Ready/Busy# Pin (RY/BY#)
– Provides a hardware method of detecting program or erase cycle
completion
? Hardware Reset Pin (R*ET#)
– Hardware method to reset the device to reading array data
? WP# input pin
– For boot sector devices: at VIL
, protects first or last 16 Kbyte sector
depending on boot configuration (* boot or bottom boot)
