Mobile DiskOnChip P3
256Mb Flash Disk with
M-Systems’ x2 Technology
Preliminary Data Sheet, June 2003
Highlights
Mobile DiskOnChip™ P3, a member of
M-Systems’ DiskOnChip™ family of
optimized memory solutions for new-generation
mobile handsets, provides high performance
and reliability using NAND flash technology. It
combines Toshiba’s cutting-edge 0.13 micron
NAND flash manufacturing process enhanced
for performance and reliability with
M-Systems’ x2 technology.
Mobile DiskOnChip P3 optimizes real estate
and cost structure by incorporating the flash
array and an embedded thin controller in a
single die. A boot block can be used to boot the
OS or initialize the CPU/platform, replacing
expensive NOR flash and further reducing
memory system costs.
Mobile DiskOnChip P3 provides:
Flash disk for both code and data storage
Low voltage: 1.8V or 3.3 I/O (auto-detect),
3V Core
Hardware protection and security-enabling
features
High capacity: 256Mbit (32MByte)
Device cascading option: up to 1Gbit
(128MByte)
Enhanced Programmable Boot Block
enabling eXecute In Place (XIP)
functionality using 16-bit interface
Small form factors:
48-pin TSOP-I package
85-ball FBGA 7x10x1.2 mm package
Enhanced performance with:
Multi-plane operation
DMA support
MultiBurst operation
Turbo operation
Unrivaled data integrity with a robust Error
Detection Code/Error Correction Code
(EDC/ECC)
Maximized flash endurance with TrueFFS
®
6.1 (and higher) flash management software
Support for major mobile OSs, including:
Symbian OS, Pocket PC 2002/3,
Smartphone 2002/3, Palm OS, Nucleus,
Linux, Windows CE
Compatible with major mobile CPUs,
including TI OMAP, XScale, Motorola
DragonBall MX1 and Qualcomm
MSMxxxx.
