Am42DL32x4G
Stacked Multi-Chip Package (MCP) Flash Memory and SRAM
32 Megabit (4 M x 8-Bit/2 M x 16-Bit) CMOS 3.0 Volt-only, Simultaneous Operation Flash Memory and 4 Mbit (256 K x 16-Bit) Static RAM DISTINCTIVE CHARACTERISTICS MCP Features
■ Power supply voltage of 2.7 to 3.3 volt ■ High performance
— Flash Access time as fast as 70 ns — SRAM access time as fast as 55 ns
SOFTWARE FEATURES
■ Data Management Software (DMS)
— AMD-supplied software manages data programming and erasing, enabling EEPROM emulation — Eases sector erase limitations
■ Package
— 73-Ball FBGA
■ Supports Common Flash Memory Interface (CFI) ■ Erase Suspend/Erase Resume
— Suspends erase operations to allow programming in same bank
■ Operating Temperature
— –40°C to +85°C
■ Data# Polling and Toggle Bits
— Provides a software method of detecting the status of program or erase cycles
Flash Memory Features
ARCHITECTURAL ADVANTAGES
■ Simultaneous Read/Write operations
— Data can be continuously read from one bank while executing erase/program functions in other bank — Zero latency between read and write operations
■ Unlock Bypass Program command
— Reduces overall programming time when issuing multiple program command sequences
HARDWARE FEATURES
■ Any combination of sectors can be erased ■ Ready/Busy# output (RY/BY#)
— Hardware method for detecting program or erase cycle completion
■ Secured Silicon (SecSi) Sector: Extra 256 Byte sector
— Factory locked and identifiable: 16 bytes available ……
