5.0 Volt single power supply operation
— Minimizes system-level power requirements
High performance
— Access times as fast as 70 ns
Manufactured on 0.32 µm process technology
Ultra low power consumption (typical values at
5 MHz)
— 20 mA typical active read current
— 30 mA typical program/erase current
— 1 µA typical standby mode current
Flexible sector architecture
— One 16 Kbyte, two 8 Kbyte, one 32 Kbyte, and
— Supports full chip erase
— Sector Protection features:
seven 64 Kbyte sectors
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
Top or bottom boot block configurations available
Minimum 1,000,000 write cycle guarantee per
sector
Package option
— 32-pin PLCC
Compatible with JEDEC standards
— Pinout and software compatible with single-
— Superior inadvertent write protection
Embedded Algorithms
— Embedded Erase algorithm automatically
— Embedded Program algorithm automatically
Erase Suspend/Erase Resume
— Suspends an erase operation to read data from,
Data# Polling and toggle bits
— Provides a software method of detecting
20-year data retention at 125°C
power supply Flash
preprograms and erases the entire chip or any
combination of designated sectors
writes and verifies data at specified addresses
or program data to, a sector that is not being
erased, then resumes the erase operation
program or erase operation completion
