2 Megabit (256 K x 8-Bit) CMOS 5.0 Volt-only Boot Sector Flash Memory
DISTINCTIVE CHARACTERISTICS
s Single power supply operation — 5.0 Volt-only operation for read, erase, and program operations — Minimizes system level requirements s High performance — Access times as fast as 55 ns s Low power consumption (typical values at 5 MHz) — 1 A standby mode current — 20 mA read current — 30 mA program/erase current s Flexible sector architecture — One 16 Kbyte, two 8 Kbyte, one 32 Kbyte, and three 64 Kbyte sectors — 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 via programming equipment Temporary Sector Unprotect feature allows code changes in previously locked sectors s Top or bottom boot block configurations available s 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 s Minimum 100,000 write cycle guarantee per sector s Package option — 32-pin PDIP — 32-pin TSOP — 32-pin PLCC s Compatibility with JEDEC standards — Pinout and software compatible with singlepower supply Flash — Superior inadvertent write protection s Data# Polling and toggle bits — Provides a software method of detecting program or erase operation completion s Erase Suspend/E……
