iNADN Standard
SanDisk iNAND devices are fully compatible with the SDA
Physical Layer Specification, Version 2.00. This specification is
available from the SD Card Association (SDA).

Why is iNAND?
7
iNAND Vs. Embedded Raw NAND
• No support for MLC
– Supporting each new revision of MLC will mean
firmware or hardware changes in host CPU
• Changing error correction requirements
– Higher densities bring higher error correction rates
– MLC brings even more requirements
• Systems need complex management and reliability
algorithms
– More challenging logical to physical management
– More frequent exception handling
– Higher performance requirements
8
iNAND Is Your Design Solution
• Embedded storage solution in a single package
– Controller + memory
• Interface
– Secure Digital (SD)
• Internal MLC – memory management
– Wear-leveling
– Error correction
– Ever changing block and page sizes
• Pinout/footprint consistent across capacity points
– Allows manufacturing flexibility and easy upgradeability
• Capacity
– 512MB to 8GB

iNAND is JEDEC compatible
•
JEDEC foot print:
–
–
•
Common SD/MMC driver - supported by
all OS

Host should support SD I/F, same as used
for SD cards

JEDEC compatible package sizes: 11.5mm
x 13mm; 12mm x 16mm; 12mm x 18mm
JEDEC compatible Ball-out1
Current iNAND supports 3.3V range
(2.7~3.6v)
1.8V I/O support
iNAND external capacitor and timing spec
different
Note: Balls [C12:M14] (total of 30 balls) in iNAND are reserved (DNU) for testing/debug and therefore should be left floated.

iNAND Pinout
• One PCB for all
capacity options
– Only 6 signal balls
– JC64 FBGA 169 ball
0.5mm ball pitch,
package
• 12 x 16 x 1.2 mm
12 x 18 x 1.2 mm
• Layout recommendation

SanDisk iNAND Value
Proposition
• Mass storage
– High-capacity embedded flash storage in a small,
JEDEC (JC-64.1) compatible package and ball-out.
– proven reliability
– easy upgrade
• Industry-standard interface
– Based on industry-standard SD interface
– Offers seamless hardware and software integration
– Fully backward compatible, significantly minimizing
design risks
