MX25U6435F
1.8V 64M-BIT [x 1/x 2/x 4] CMOS MXSMIO
®
(SERIAL MULTI I/O)
FLASH MEMORY
1. FEATURES
GENERAL
• Supports Serial Peripheral Interface -- Mode 0 and Mode 3
•
67,108,864 x 1 bit structure or 33,554,432 x 2 bits (two I/O mode) structure or 16,777,216 x 4 bits (four I/O
mode) structure
• Equal Sectors with 4K byte each, or Equal Blocks with 32K byte each or Equal Blocks with 64K byte each
- Any Block can be erased individually
• Single Power Supply Operation
- 1.65 to 2.0 volt for read, erase, and program operations
• Latch-up protected to 100mA from -1V to Vcc +1V
• Low Vcc write inhibit is from 1.0V to 1.4V
PERFORMANCE
• High Performance
- Fast read for SPI mode
- 1 I/O: 104MHz with 8 dummy cycles
- 2 I/O: 84MHz with 4 dummy cycles, equivalent to 168MHz
- 4 I/O: 104MHz with 2+4 dummy cycles, equivalent to 416MHz
- Fast read for QPI mode
- 4 I/O: 84MHz with 2+2 dummy cycles, equivalent to 336MHz
- 4 I/O: 104MHz with 2+4 dummy cycles, equivalent to 416MHz
- Fast program time: 0.5ms(typ.) and 3ms(max.)/page (256-byte per page)
- Byte program time: 12us (typical)
- 8/16/32/64 byte Wrap-Around Burst Read Mode
- Fast erase time: 35ms (typ.)/sector (4K-byte per sector); 200ms(typ.)/block (32K-byte per block), 350ms(typ.) /
block (64K-byte per block)
• Low Power Consumption
- Low active read current: 20mA(typ.) at 104MHz, 15mA(typ.) at 84MHz
- Low active erase current: 18mA (typ.) at Sector Erase, Block Erase (32KB/64KB); 20mA at Chip Erase
- Low active programming current: 20mA (typ.)
- Standby current: 15uA (typ.)
• Deep Power Down: 1.5uA(typ.)
• Typical 100,000 erase/program cycles
• 20 years data retention
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 instruc-
tions
- Additional 4k-bit secured OTP for unique identifier
• Auto Erase and Auto Program Algorithm
-
Automatically erases and verifies data at selected sector or block
-
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)
