Numonyx™ Wireless Flash Memory (W18)

1.2

Conventions

Table 2:

Conventions

Refers to the full V_CCvoltage range of 1.7 V – 1.95 V (except where noted) and “V_PP= 12 V” refers to 12 V

±5%.

“1.8 V”

Set

Refers to registers means the bit is a logical 1 and cleared means the bit is a logical 0.

Often used interchangeably to refer to the external signal connections on the package (ball is the term used for

VF BGA).

Pin and signal

Word

2 bytes or 16 bits.

Signal

Voltage

Names are in all CAPS (see Section 4.2, “Signal Descriptions” on page 18.)

Applied to the signal is subscripted for example V_PP

Throughout this document, references are made to top, bottom, parameter, and partition. To clarify these references, the

following conventions have been adopted:

Block

A group of bits (or words) that erase simultaneously with one block erase instruction.

Contains 32-Kwords.

Main block

Parameter

block

Contains 4-Kwords.

Block Base

Address (BBA)

The first address of a block.

Partition

A group of blocks that share erase and program circuitry and a common Status Register.

Partition Base

Address (PBA)

The first address of a partition. For example, on a 32-Mbit top-parameter device partition number 5 has a PBA

of 0x140000.

Top partition

Located at the highest physical device address. This partition may be a main partition or a parameter partition.

Located at the lowest physical device address. This partition may be a main partition or a parameter partition.

Contains only main blocks.

Bottom

partition

Main partition

Parameter

partition

Contains a mixture of main blocks and parameter blocks.

Top parameter Has the parameter partition at the top of the memory map with the parameter blocks at the top of that

device

partition. This was formerly referred to as a Top-Boot device.

Bottom

parameter

device (BPD)

Has the parameter partition at the bottom of the memory map with the parameter blocks at the bottom of that

partition. This was formerly referred to as a Bottom-Boot Block flash device.
