Introduction
This document provides information about the Numonyx™ StrataFlash® wireless
memory (L30) device and describes the Numonyx™ StrataFlash® Wireless Memory
(L30) features, operation, and specifications.
The Numonyx StrataFlash® wireless memory (L30) product is the latest generation of
Numonyx StrataFlash® memory devices featuring flexible, multiple-partition, dual
operation. It provides high performance synchronous-burst read mode and
asynchronous read mode using 1.8 V low-voltage, multi-level cell (MLC) technology.
The multiple-partition architecture enables background programming or erasing to
occur in one partition while code execution or data reads take place in another
partition. This dual-operation architecture also allows a system to interleave code
operations while program and erase operations take place in the background.
The L30 device is manufactured using Intel 0.13 µm ETOX* VIII process technology. It
is available in industry-standard chip scale packaging.
Nomenclature
• 1.8 V: VCC voltage range of 1.7 V – 2.0 V (except where noted)
• 3.0 V Range: VCCQ voltage range of 2.2 V – 3.3 V
• VPP = 9.0 V: VPP voltage range of 8.5 V – 9.5 V
• Block: A group of bits, bytes or words within the flash memory array that erase
simultaneously when the Erase command is issued to the device. The Numonyx™
StrataFlash® Wireless Memory (L30) has two block sizes: 16-Kword, and 64-Kword.
• Main block: An array block that is usually used to store code and/or data. Main
blocks are larger than parameter blocks.
• Parameter block: An array block that is usually used to store frequently changing
data or small system parameters that traditionally would be stored in EEPROM.
• Top parameter device: Previously referred to as a top-boot device, a device with
its parameter partition located at the highest physical address of its memory map.
Parameter blocks within a parameter partition are located at the highest physical
address of the parameter partition.
• Bottom parameter device: Previously referred to as a bottom-boot device, a
device with its parameter partition located at the lowest physical address of its
memory map. Parameter blocks within a parameter partition are located at the
lowest physical address of the parameter partition.
• Partition: A group of blocks that share common program/erase circuitry. Blocks
within a partition also share a common status register. If any block within a
partition is being programmed or erased, only status register data (rather than
array data) is available when any address within that partition is read.
• Main partition: A partition containing only main blocks.
• Parameter partition: A partition containing parameter blocks and main blocks.
