PERFORMANCE
• High Performance
- Fast access time: 86MHz serial clock (15pF + 1TTL Load) and 66MHz serial clock (30pF + 1TTL Load)
- Serial clock of two I/O read mode : 50MHz (15pF + TTL Load), which is equivalent to 100MHz
- Fast program time: 1.4ms(typ.) and 5ms(max.)/page (256-byte per page)
- Byte program time: 7us (typical)
- Continuously program mode (automatically increase address under word program mode)
- Fast erase time: 60ms(typ.) /sector (4K-byte per sector) ; 0.7s(typ.) /block (64K-byte per block); 25s(typ.) for 32Mb
· Low Power Consumption
- Low active read current: 25mA(max.) at 86MHz, 20mA(max.) at 66MHz and 10mA(max.) at 33MHz
- Low active programming current: 20mA (max.)
- Low active erase current: 20mA (max.)
- Low standby current: 20uA (max.)
- Deep power-down mode 1uA (typical)
· Typical 100,000 erase/program cycles
SOFTWARE FEATURES
· Input Data Format
- 1-byte Command code
· Advanced Security Features
- Block lock protection
The BP0-BP3 status bit defines the size of the area to be software protection against program and erase instructions
- Additional 512-bit secured OTP for unique identifier
· Auto Erase and Auto Program Algorithm
- Automatically erases and verifies data at selected sector
- Automatically programs and verifies data at selected page by an internal algorithm that automatically times the program pulse widths (Any page to be
