Description
Spansion S29AL004D70TFI020 NOR Flash Parallel 3V/3.3V 4M-bit 512K x 8/256K x 16 70ns 48-Pin TSOP Tray
8 Megabit x 16-Bit) CMOS 3.0 Volt-only Boot Sector Flash Memory
to 3.6 volt read and write operations for batterypowered applications
Access times as fast 55 ns Extended temperature range to +125°C)
Ultra low power consumption (typical values at 5 MHz)
200 nA Automatic Sleep mode current 200 nA standby mode current 7 mA read current 15 mA program/erase current
One 16 Kbyte, two 8 Kbyte, one 32 Kbyte, and fifteen 64 Kbyte sectors (byte mode) One 8 Kword, two 4 Kword, one 16 Kword, and fifteen 32 Kword sectors (word mode) Supports full chip erase Sector Protection features: A hardware method of locking a sector to prevent any program or erase operations within that sector Sectors can be locked in-system or via programming equipment Temporary Sector Unprotect feature allows code changes in previously locked sectors
Cycling endurance: 1,000,000 cycles per sector typical Data retention: 20 years typical
Reduces overall programming time when issuing multiple program command sequences
Provides a software method of detecting program or erase operation completion
Top or bottom boot block configurations available Embedded Algorithms
Embedded Erase algorithm automatically preprograms and erases the entire chip or any combination of designated sectors Embedded Program algorithm automatically writes and verifies data at specified addresses
