S29AS008J
8 Mbit (1M x 8-Bit / 512K x 16-Bit), 1.8 V
Boot Sector Flash
Distinctive Characteristics
Architectural Advantages
Single Power Supply Operation
– Full voltage range: 1.65 to 1.95 volt read and write operations for
battery-powered applications
Manufactured on 110 nm Process Technology
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
– Eight 8 Kbyte and fifteen 64 Kbyte sectors (byte mode)
– Eight 4 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 Group Unprotect feature allows code changes
in previously locked sectors
Unlock Bypass Program Command
– Reduces overall programming time when issuing multiple program
command sequences
Top or Bottom Boot Block Configurations Available
Compatibility with JEDEC standards
– Pinout and software compatible with single-power supply Flash
– Superior inadvertent write protection
Performance Characteristics
High Performance
– Access times as fast as 70 ns
– Industrial temperature range (-40°C to +85°C)
– Word programming time as fast as 6 µs (typical)
Ultra Low Power Consumption (typical values at 5 MHz)
– 15 µA Automatic Sleep mode current
– 8 µA standby mode current
– 8 mA read current
– 20 mA program/erase current
Cycling Endurance: 1,000,000 cycles per sector typical
Data Retention: 20 years typical
Package Options
48-ball 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 (RESET#)
– Hardware method to reset the device to reading array data
WP# input pin
– Write protect (WP#) function allows protection of two outermost
boot sectors (boot sector models only), regardless of sector group
protect status
