Its symmetrically-blocked architecture, flexible voltage and extended cycling provide for highly flexible component suitable for resident flash arrays, SIMMs and memory cards. 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 LH28F008SCT-L85 offers three levels of protection: absolute protection with VPP at GND, selective hardware block locking, or flexible software block locking. These alternatives give designers ultimate control of their code security needs. The LH28F008SCT-L85 is manufactured on SHARP’s 0.38µm ETOXTM process technology. It come in industry-standard package: the 40-lead TSOP, ideal for board constrained applications. Based on the 28F008SA architecture, the LH28F008SCT-L85 enables quick and easy upgrades for designs demanding the state-of-the-art. *ETOX is a trademark of Intel Corporation. Rev. 1.3 sharp LHF08CH1 1 INTRODUCTION This datasheet contains LH28F008SCT-L85 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. LH28F008SCT-L85 Flash memory documentation also includes application notes and design tools which are referenced in Section 7. 1.1 New Features The LH28F008SCT-L85 SmartVoltage Flash memory maintains backwards-compatibility with SHARP’s 28F008SA. Key enhancements over the 28F008SA include: •SmartVoltage Technology •Enhanced Suspend Capabilities •In-System Block Locking Both devices share a compatible pinout, status register, and software command set. These similarities enable a clean upgrade from the 28F008SA to LH28F008SCT-L85. When upgrading, it is important to note the following differences: •Because of new feature support, the two devices have different device codes. This allows for software optimization. •VPPLK has been lowered from 6.5V to 1.5V to support 3.3V and 5V block erase, byte write, and lock-bit configuration operations. The VPP voltage transitions to GND is recommended for designs that switch VPP off during read operation. •To take advantage of SmartVoltage technology, allow VPP connection to 3.3V or 5V. 1.2 Product Overview The LH28F008SCT-L85 is a high-performance 8M-bit SmartVoltage Flash memory organized as 1M-byte of 8 bits. The 1M-byte of data is arranged in sixteen 64K-byte blocks which are individually erasable, lockable, and unlockable in-system. The memory map is shown in Figure 3. 3 SmartVoltage technology provides a choice of VCC and VPP combinations, as shown in Table 1, to meet system performance and power expectations. 2.7V VCC consumes approximately one-fifth the power of 5V VCC. But, 5V VCC provides the highest read performance. VPP at 3.3V and 5V eliminates the need for a separate 12V converter, while VPP=12V maximizes block erase and byte write performance. In addition to flexible erase and program voltages, the dedicated VPP pin gives complete data protection when VPP≤VPPLK. Table 1.
