Simultaneous Read/Write operations
-Host system can program or erase in one bank,
then immediately and simultaneously read from the other bank
-Zero latency between read and write operations
-Read-while-erase
-Read-while-program
Single power supply operation
-2.7 to 3.6 volt read and write operations for battery-powered applications
Manufactured on 0.35 µm process technology
High performance
-Access times as fast as 70 ns
Low current consumption (typical values at 5 MHz)
-7 mA active read current
-21 mA active read-while-program or read-while-erase current
-17 mA active program-while-erase-suspended current
-200 nA in standby mode
-200 nA in automatic sleep mode
-Standard tCE chip enable access time applies to
transition from automatic sleep mode to active mode
Flexible sector architecture
-Two 16 Kword, two 8 Kword, four 4 Kword, and six 32 Kword sectors in word mode
-Two 32 Kbyte, two 16 Kbyte, four 8 Kbyte, and six 64 Kbyte sectors in byte mode
-Any combination of sectors can be erased
-Supports full chip erase
Unlock Bypass Program Command
-Reduces overall programming time when issuing multiple program command sequences
Sector protection
-Hardware method of locking a sector to prevent
any program or erase operation within that sector
-Sectors can be locked in-system or via programming equipment
-Temporary Sector Unprotect feature allows code changes in previously locked sectors
Top or bottom boot block configurations available
Embedded Algorithms
-Embedded Erase algorithm automatically pre-programs and erases sectors or entire chip
-Embedded Program algorithm automatically programs and verifies data at specified address
Minimum 1 million program/erase cycles guaranteed per sector
Package options
-44-pin SO
-48-pin TSOP
Compatible with JEDEC standards
-Pinout and software compatible with single-power-supply flash standard
-Superior inadvertent write protection
Data# Polling and Toggle Bits
-Provides a software method of detecting program or erase cycle completion
Ready/Busy# output (RY/BY#)
-Hardware method for detecting program or erase cycle completion
Erase Suspend/Erase Resume
-Suspends or resumes erasing sectors to allow reading and programming in other sectors
-No need to suspend if sector is in the other bank
Hardware reset pin (RESET#)
-Hardware method of resetting the device to reading array data
