Conventions
The following abbreviated terms and phrases are used throughout this document:
Throughout this document, references are made to top, bottom, parameter, and
partition. To clarify these references, the following conventions have been adopted:
• RWE - Read-While-Erase
• RWW - Read-While-Write
• SCSP - Stacked Chip Scale Package
• SRD - Status Register Data
• VF BGA - Very-thin, Fine-pitch, Ball Grid Array
• WSM - Write State Machine
• 1.8 V refers to the V
• 3.0 V refers to the V
• V
• When referring to registers, the term set means the bit is a logical 1, and cleared
• The terms pin and signal are often used interchangeably to refer to the external
• A word is 2 bytes, or 16 bits.
• Signal names are in all CAPS (for example, WAIT).
• Voltage applied to the signal is subscripted (for example, V
• A block is a group of bits (or words) that erase simultaneously with one block
• 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
• The Partition Base Address (PBA) is the first address of a partition. For example,
• The top partition is located at the highest physical flash device address. This
• The bottom partition is located at the lowest physical flash device address. This
• A main partition contains only main blocks.
• A parameter partition contains a mixture of main blocks and parameter blocks.
• A top parameter device (TPD) has the parameter partition at the top of the
