- All Pb-free products are RoHS-Compliant
⢠Low Vcc write inhibit
⢠Manufactured on 0.18um process technology
⢠Compatible with JEDEC standards
- Pinout and software compatible with single-power
supply flash standard
DEVICE PERFORMANCE
⢠Read access time
- 70ns/90ns for normal Vcc range ( 2.7V ~ 3.6V )
⢠Program and erase time
- Program time : 6us/byte, 8us/word ( typical )
- Accelerated program time : 4us/word ( typical )
- Sector erase time : 0.7sec/sector ( typical )
⢠Power consumption (typical values)
- 15uA in standby or automatic sleep mode
- 10mA active read current at 5MHz
- 15mA active write current during program or erase
⢠Minimum 100,000 program/erase cycles per sector
⢠20 Year data retention at 125oC
SOFTWARE FEATURES
⢠Erase Suspend / Erase Resume
⢠Data# poll and toggle for Program/erase status
⢠CFI ( Common Flash Interface) supported
⢠Unlock Bypass Program
⢠Autoselect mode
⢠Auto-sleep mode after tACC + 30ns
HARDWARE FEATURES
⢠Hardware reset input pin (RESET#)
- Provides a hardware reset to device
- Any internal device operation is terminated and the
device returns to read mode by the reset
⢠Ready/Busy# output pin (RY/BY#)
- Provides a program or erase operational status
about whether it is finished for read or still being
progressed
⢠WP#/ACC input pin
- Two outermost boot sectors are protected when
WP# is set to low, regardless of sector protection
- Program speed is accelerated by raising WP#/ACC
to a high voltage (11.5V~12.5V)
⢠Sector protection / unprotection (RESET# , A9 )
- Hardware method of locking a sector to prevent
any program or erase operation within that sector
- Two methods are provided :
- In-system method by RESET# pin
- A9 high-voltage method for PROM programmers
⢠Temporary Sector Unprotection (RESET# )
- Allows temporary unprotection of previously
protected sectors to change data in-system
