7 / 100 page 28F640L30, 28F128L30, 28F256L30 Datasheet 7 1.0 Introduction This document provides information about the 1.8 Volt Intel StrataFlash ® wireless memory with 3-Volt I/O (L30) device. This document describes the L30 flash memory device features, operation, and specifications. 1.1 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 L30 flash memory device has two block sizes: 16K-Word, and 64K-Word. 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. 1.2 Acronyms CUI: Command User Interface MLC: Multi-Level Cell OTP: One-Time Programmable PLR: Protection Lock Register PR: Protection Register RCR: Read Configuration Register RFU: Reserved for Future Use SR: Status Register WSM: Write State Machine |
