Am29BDD160G Known Good Die—Die Revision 1
16 Megabit (1 M x 16-Bit/512 K x 32-Bit)
CMOS 2.5 Volt-only Burst Mode, Dual Boot, Simultaneous Read/Write Flash Memory
DISTINCTIVE CHARACTERISTICS
ARCHITECTURE ADVANTAGES
■
Ultra low power consumption
— Burst Mode Read: 90 mA @ 56 MHz max
— Program/Erase: 50 mA max
— Standby mode: CMOS: 250 µA max
■
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
— Two bank architecture: 75%/25%
■
User-Defined x16 or x32 Data Bus
■
Dual Boot Block
— Top and bottom boot in the same device
■
Minimum 1 million write cycles guaranteed per sector
■
20 year data retention at 125
°
C
■
VersatileI/O™ control
— Device generates data output voltages and tolerates data
input voltages as determined by the voltage on the V
IO
pin
— 1.65 V to 2.75 V compatible I/O signals
■
Flexible sector architecture
— Eight 8 Kbytes, thirty 64 Kbytes, and eight 8 Kbytes
sectors
SOFTWARE FEATURES
■
Manufactured on 0.17 µm process technology
■
SecSi (Secured Silicon) Sector (256 Bytes)
—
Factory locked and identifiable:
16 bytes for secure,
random factory Electronic Serial Number; remainder may
be customer data programmed by AMD
—
Customer lockable:
Can be read, programmed or erased
just like other sectors. Once locked, data cannot be
changed
■
Persistent Sector Protection
— A command sector protection method to lock
combinations of individual sectors and sector groups to
prevent program or erase operations within that sector
(requires only V
CC
levels)
— A sophisticated sector protection method to lock
combinations of individual sectors and sector groups to
prevent program or erase operations within that sector
using a user-definable 64-bit password
■
Password Sector Protection
■
Programmable Burst interface
— Interface to any high performance processor
— Modes of Burst Read Operation:
—
Linear Burst:
4 double words (x32), 8 words (x16) and
double words (x32), and 32 words (x16) with wrap
around
■
Supports Common Flash Interface (CFI)
■
Unlock Bypass Program Command
— Reduces overall programming time when issuing multiple
program command sequences
■
Single power supply operation
— Optimized for 2.5 to 2.75 Volt read, erase, and program
operations
■
Data# Polling and toggle bits
— Provides a software method of detecting program or erase
operation completion
■
Compatibility with JEDEC standards (JC42.4)
— Software compatible with single-power supply Flash
— Backward-compatible with AMD Am29LV and Am29F
flash memories
HARDWARE FEATURES
■
Program Suspend/Resume & Erase Suspend/Resume
— Suspends program or erase operations to allow reading,
programming, or erasing in same bank
PERFORMANCE CHARACTERISTICS
■
Hardware Reset (RESET#), Ready/Busy# (RY/BY#),
and Write Protect (WP#) inputs
■
ACC input
— Accelerates programming time for higher throughput
during system production
■
High performance read access
— Initial/random access times as fast as 64 ns
— Burst access time as fast as 10 ns
■
Quality and reliability levels equivalent to standard
packaged components
