FEATURES
32M-BIT [4M x 8 / 2M x 16] CMOS EQUAL SECTOR
FLASH MEMORY
GENERAL FEATURES
• 4,194,304 x 8 / 2,097,152 x 16 switchable
• Sixty-Four Equal Sectors with 32K word/ 64K byte
- Any combination of sectors can be erased with erase suspend/resume function
• Single Power Supply Operation
- 2.7 to 3.6 volt for read, erase, and program operations
• Latch-up protected to 100mA from -1V to 1.5 x Vcc
• Low Vcc write inhibit is equal to or less than VLKO
• Compatible with JEDEC standard
- Pinout and software compatible to single power supply Flash
PERFORMANCE
• High Performance
- Access time: 70ns
- Program time: 11us/word (typical)
- Erase time: 0.7s/sector, 35s/chip (typical)
• Low Power Consumption
- Low active read current: 9mA (typical) at 5MHz
- Low standby current: 5uA(typical)
• Typical 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
• Erase Suspend/ Erase Resume
- Suspends sector erase operation to read data from or program data to another sector which is not being
erased
• 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
• ACC input pin
- Provides accelerated program capability
• WP# input pin
- Write protect (WP#) function allows protection highest or lowest sector, regardless of sector protection set-
tings
SECURITY
• Sector Protection/Chip Unprotect
- Provides sector protect function to prevent program or erase operation in the protected sector
- Provides chip unprotect function to allow code changes
- Provides temporary sector unprotect function for code changes in previously protected sectors

Notes:
1. Through programming equipment, the sector protect and chip unprotect functions can also be implemented.
2. If WP#=L, all sectors are protected. If WP# remove to H, all sectors recover previous protected or unprotected
status, determined by "sector protect" or "chip unprotect" function.
3. By following the requests of command sequence, sector protection, or data polling algorithm, Q0~Q15 would
be Data Input or Data Output.
4. In Word mode, A20~A0 are address pins. In Byte mode A20~A-1 are address pins. In both modes, A20~A15
are sector address.
