The product is a high-density, low-cost, nonvolatile, read/write storage solution for a wide range of applications. The product can operate at VCC=2.7V-3.6V and VCCW=2.7V-3.6V or 11.7V-12.3V. Its low voltage operation capability realize battery life and suits for cellular phone application. Its Boot, Parameter and Main-blocked architecture, low voltage and extended cycling provide for highly flexible component suitable for portable terminals and personal computers. Its enhanced suspend capabilities provide for an ideal solution for code + data storage applications. For secure code storage applications, such as networking, where code is either directly executed out of flash or downloaded to DRAM, the product offers four levels of protection: absolute protection with VCCW≤VCCWLK, selective hardware block locking or flexible software block locking. These alternatives give designers ultimate control of their code security needs. The product is manufactured on SHARP’s 0.25µm ETOXTM* process technology. It come in industry-standard package: the 48-lead TSOP, ideal for board constrained applications. *ETOX is a trademark of Intel Corporation.

1 INTRODUCTION
This datasheet contains the product specifications. Section 1 provides a flash memory overview. Sections 2, 3, 4 and 5 describe the memory organization and functionality. Section 6 covers electrical specifications.
1.1 Features
Key enhancements of the product are: •Single low voltage operation •Low power consumption •Enhanced Suspend Capabilities •Boot Block Architecture Please note following: •VCCWLK has been lowered to 1.0V to support 2.7V3.6V block erase, full chip erase, word/byte write and lock-bit configuration operations. The VCCW voltage transitions to GND is recommended for designs that switch VCCW off during read operation.
A block erase operation erases one of the device’s 32Kword/64K-byte blocks typically within 1.2s (3V VCC, 3V VCCW), 4K-word/8K-byte blocks typically within 0.6s (3V VCC, 3V VCCW) independent of other blocks. Each block can be independently erased minimum 100,000 times. Block erase suspend mode allows system software to suspend block erase to read or write data from any other block. Writing memory data is performed in word/byte increments of the device’s 32K-word blocks typically within
