MX25L3255D
32M-BIT [x 1/x 2/x4] CMOS MXSMIO
TM
(SERIAL MULTI I/O) FLASH MEMORY
FEATURES
GENERAL
• Serial Peripheral Interface compatible -- Mode 0 and Mode 3
•
33,554,432 x 1 bit structure or 16,772,216 x 2 bits (two I/O read mode) structure or 8,388,608 x 4 bits (four I/O
read mode) structure
• 1024 Equal Sectors with 4K byte each
- Any Sector can be erased individually
• 64 Equal Blocks with 64K byte each
- Any Block can be erased individually
• Single Power Supply Operation
- 2.7 to 3.6 volt for read, erase, and program operations
• Latch-up protected to 100mA from -1V to Vcc +1V
PERFORMANCE
• High Performance
- Fast read
- 1 I/O: 104MHz with 8 dummy cycles
- 4 I/O: 75MHz with 6 dummy cycles for 4READ; 75MHz with 8 dummy cycles for QREAD
- 2 I/O: 75MHz with 4 dummy cycles for 2READ; 75MHz with 8 dummy cycles for DREAD
- Fast access time: 104MHz serial clock
- Serial clock of four I/O read mode : 75MHz, which is equivalent to 300MHz
- Fast program time: 1.4ms(typ.) and 5ms(max.)/page (256-byte per page)
- Byte program time: 9us (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.) /chip
• Low Power Consumption
- Low active read current: 25mA(max.) at 104MHz, 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.)
• Typical 100,000 erase/program cycles
• 20 years data retention
SOFTWARE FEATURES
• Input Data Format
- 1-byte Command code
• Advanced Security Features
- Block Write Lock protection
- Additional 4K-bit secured OTP for unique identifier
- Permanent lock
- Read protection function
• 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 programed should have page in the erased state first)
1 Introduction
In the mid-1960s, American scientist Maas conducted extensive experimental research on the charging process of open-cell batteries and proposed an acceptable charging curve for ...[详细]
