Circuit-, IC descriptions and list of abbreviations
16 Megabit (2 M x 8-Bit/1 M x 16-Bit)
CMOS 3.0 Volt-only Sector Erase Flash Memory
I Single power supply operation
— Full voltage range: 2.7 to 3.6 volt read and write
operations for battery-powered applications
— Regulated voltage range: 3.0 to 3.6 volt read
and write operations and for compatibility with
high performance 3.3 volt microprocessors
I Manufactured on 0.35 µm process technology
I Supports Common Flash Memory Interface
I High performance
— Full voltage range: access times as fast as 90 ns
— Regulated voltage range: access times as fast
as 80 ns
I Ultra low power consumption (typical values at
5 MHz)
— 200 nA Automatic Sleep mode current
— 200 nA standby mode current
— 10 mA read current
— 20 mA program/erase current
I Flexible sector architecture
— One 16 Kbyte, two 8 Kbyte, one 32 Kbyte, and
thirty-one 64 Kbyte sectors (byte mode)
— One 8 Kword, two 4 Kword, one 16 Kword, and
thirty-one 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
SACD 1000
I Top or bottom boot block configurations
I 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
I Minimum 100,000 write cycle guarantee per
I Package option
— 48-ball FBGA
— 48-ball µBGA
— 48-pin TSOP
— 44-pin SO
I Compatibility with JEDEC standards
— Pinout and software compatible with single-
power supply Flash
— Superior inadvertent write protection
I Data# Polling and toggle bits
— Provides a software method of detecting
program or erase operation completion
I Ready/Busy# pin (RY/BY#)
— Provides a hardware method of detecting
program or erase cycle completion (not
available on 44-pin SO)
I Erase Suspend/Erase Resume
— Suspends an erase operation to read data from,
or program data to, a sector that is not being
erased, then resumes the erase operation
I Hardware reset pin (RESET#)
— Hardware method to reset the device to reading
array data
GB 123
