FEATURES

GENERAL FEATURES

? Single Power Supply Operation

- 2.7 to 3.6 volt for read, erase, and program operations

? 8,388,608 x 8 / 4,194,304 x 16 switchable

? Sector structure

- 8KB (4KW) x 8 and 64KB(32KW) x 127

? Sector Protection/Chip Unprotect

- Provides sector group protect function to prevent

program or erase operation in the protected sector

group

- Provides chip unprotect function to allow code

changes

- Provides temporary sector group unprotect function

for code changes in previously protected sector groups

? Secured Silicon Sector

- Provides a 128-word area for code or data that can

be permanently protected

- Once this sector is protected, it is prohibited to program or erase within the sector again

? Latch-up protected to 250mA from -1V to Vcc + 1V

? Low Vcc write inhibit is equal to or less than 1.5V

? Compatible with JEDEC standard

- Pin-out and software compatible to single power supply Flash

PERFORMANCE

? High Performance

- Fast access time: 90ns

- Page read time: 25ns

- Sector erase time: 0.5s (typ.)

- 4 word/8 byte page read buffer

- 16 word/ 32 byte write buffer: reduces programming

time for multiple-word/byte updates

? Low Power Consumption

- Active read current: 18mA(typ.)

- Active write current: 50mA(typ.)

- Standby current: 20uA(typ.)

? Minimum 100,000 erase/program cycle

? 20-years data retention

SOFTWARE FEATURES

? Support Common Flash Interface (CFI)

- Flash device parameters stored on the device and

provide the host system to access.

? Program Suspend Resume

- Suspends programming operation to read data from

other sectors

? Erase Suspend/ Erase Resume

- Suspends sector erase operation to read/program

other sectors

? Status Reply

- Data# polling & Toggle bits provide detection of program and erase operation completion

HARDWARE FEATURES

? Ready/Busy (RY/BY#) Output

- Provides a hardware method of detecting program

and erase operation completion

? Hardware Reset (RESET#) Input

- Provides a hardware method to reset the internal

state machine to read mode

? WP#/ACC input

- Write protect (WP#) function allows protection of two

outermost boot sectors, regardless of sector protect

status

- ACC (high voltage) accelerates programming time

for higher throughput during system

PACKAGE

? 48-pin TSOP

? 63-ball CSP

? All Pb-free devices are RoHS Compliant
