PERFORMANCE
• High Performance
- Access time: 90ns
- Program time: 11us/word
- Erase time: 0.7s/sector, 45s/chip (typical)
• Low Power Consumption
- Low active read current: 9mA (typical) at 5MHz
- Low standby current: 5uA(typical)
• 100,000 erase/program cycles (typical)
• 10 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 or not
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#/ACC input
- Write protect (WP#) function allows protection highest or lowest sector, regardless of sector protection settings
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 sector
• Sector Permanent Lock
- A unique lock bit feature allows the content to be permanently locked
