.DThe 1.8 Volt Intel® Wireless Flash memory with flexible multi-partition dual-operation provides high-
performance asynchronous and synchronous burst reads. It is an ideal memory for low-voltage burst CPUs.
wCombining high read performance with flash memory’s intrinsic non-volatility, 1.8 Volt Intel Wireless Flash
memory eliminates the traditional system-performance paradigm of shadowing redundant code memory from
slow nonvolatile storage to faster execution memory. It reduces the total memory requirement that increases
wreliability and reduces overall system power consumption and cost.
mThe 1.8 Volt Intel Wireless Flash memory’s flexible multi-partition architecture allows programming or erasing to
woccur in one partition while reading from another partition. This allows for higher data write throughput
ocompared to single partition architectures. The dual-operation architecture also allows two processors to
.cinterleave code operations while program and erase operations take place in the background. The designer can
also choose the size of the code and data partitions via the flexible multi-partition architecture.
t4UThe 1.8 Volt Intel Wireless Flash memory is manufactured on Intel’s 0.18 µm ETOX™ VII process technology. It
is available in µBGA and VF BGA packages which are ideal for board-constrained applications.

1.8 Volt Intel® Wireless Flash Memory (W18)
Introduction
This datasheet contains information about the 1.8 Volt Intel® Wireless Flash memory family.
Section 1.0 provides a flash memory overview. Section 2.0 through Section 6.0 describe the
memory functionality. Section 7.0 describes the electrical specifications for extended temperature
product offerings.
Document Conventions
Many terms and phrases are used throughout this document as a short-hand version of full, and
more accurate verbiage:
• The term “1.8 V” refers to the full VCC voltage range of 1.7 V – 1.95 V (except where noted)
and “VPP = 12 V” refers to 12 V ±5%.
• When referring to registers, the term set means the bit is a ‘1’, and clear means the bit is a ‘0’.
• Even though this product supports multiple package types, the terms pin and signal are often
used interchangeably to refer to the external signal connections on the package. (e.g., balls in
the case of µBGA*).
• A word is 2 bytes, or 16 bits.
• For voltage and ground signals, the signal name is denoted in all CAPS as seen in Section 2.2,
“Signal Descriptions” on page 4, whereas the voltage applied to the signal uses subscripted
notation. For example VPP refers to a signal, while VPP is a voltage level.
Throughout this document, references are made to top, bottom, parameter, and main partitions. To
clarify these references, the following conventions have been adopted:
• A block is a group of bits (or words) that erase simultaneously with one block erase
instruction.
• A main block contains 32 Kwords.
• A parameter block contains 4 Kwords.
• The Block Base Address (BBA) is the first address of a block.
• A partition is a group of blocks that share erase and program circuitry and a common status
register. If one block is erasing or one word is programming, only the status register, rather
than array data, is available when any address within the same partition is read.
• The Partition Base Address (PBA) is the first address of a partition. For example, on a 32-
Mbit top-parameter device, partition number 5 has a PBA of 140000h.
• The top partition is located at the highest physical device address. This partition may be a
main partition or a parameter partition.
• The bottom partition is located at the lowest physical device address. This partition may be a
main partition or a parameter partition.
• A main partition contains only main blocks.
• A parameter partition contains a mixture of main and parameter blocks.
• A top parameter device (TPD) has the parameter partition at the top of the memory map with
the parameter blocks at the top of that partition. This was formerly referred to as top-boot
device.
