GENERAL DESCRIPTION This SyncFlash® data sheet is divided into two major sections. The SDRAM Interface Functional Description details compatibility with the SDRAM memory, and the Flash Memory Functional Description specifies the symmetrical-sectored flash architecture functional commands. FEATURES • 100 MHz SDRAM-compatible read timing • Fully synchronous; all signals registered on positive edge of system clock • Internal pipelined operation; column address can be changed every clock cycle • Internal banks for hiding row access • Programmable burst lengths: 1, 2, 4, 8, or full page (READ) • LVTTL-compatible inputs and outputs • Single +3.3V ±0.3V power supply – Additional VHH hardware protect mode (RP#) • Four-bank architecture supports true concurrent operations with zero latency: Read from any bank while performing a PROGRAM or ERASE operation to any other bank • Deep power-down mode: 300µA maximum • Cross-compatible Flash memory command set • Industry-standard, SDRAM-compatible pinouts – Pins 36 and 40 are no connects for SDRAM
