GENERAL DESCRIPTION The MT28F322P3 is a high-performance, highdensity, nonvolatile memory solution that can significantly improve system performance. This new architecture features a two-memory-bank configuration that supports background operation with no latency. A high-performance bus interface allows a fast page mode data transfer; a conventional asynchronous bus interface is provided as well. FEATURES • Flexible dual-bank architecture Support for true concurrent operation with zero latency Read bank a during program bank b and vice versa Read bank a during erase bank b and vice versa • Basic configuration: Seventy-one erasable blocks Bank a (8Mb for data storage) Bank b (24Mb for program storage) • VCC, VCCQ, VPP voltages 2.7V (MIN), 3.3V (MAX) VCC 2.2V (MIN), 3.3V (MAX) VCCQ 3.0V (TYP) VPP (in-system PROGRAM/ERASE) 12V ±5% (HV) VPP tolerant (factory programming compatibility) • Random access time: 70ns @ 2.7V VCC • Page Mode read access Eight-word page Interpage read access: 70ns @ 2.7V Intrapage read access: 30ns @ 2.7V • Low power consumption (VCC = 3.3V) Asynchronous/interpage READ < 15mA Intrapage READ < 7mA WRITE < 20mA (MAX) ERASE < 25mA (MAX) Standby < 15µA (TYP), 50µA (MAX) @ 3.3V Automatic power save (APS) feature • Enhanced write and erase suspend options ERASE-SUSPEND-to-READ within same bank PROGRAM-SUSPEND-to-READ within same bank ERASE-SUSPEND-to-PROGRAM within same bank • Dual 64-bit chip protection registers for security purposes • Cross-compatible command support Extended command set Common flash interface • PROGRAM/ERASE cycle 100,000 WRITE/ERASE cycles per block • Fast programming algorithm VPP = 12V ±5%
