Description

Features:

Single 1.8 volt read, program and erase (1.7 to 1.9 volt)
Multiplexed Data and Address for reduced I/O count
- A0A15 multiplexed as D0D15
- Addresses are latched with AVD# control inputs while CE# low
Simultaneous Read/Write operation
- Data can be continuously read from one bank
while executing erase/program functions in other bank
- Zero latency between read and write operations
Read access times at 54 MHz/40 MHz
- Burst access times of 13.5/20 ns @ 30 pF at industrial temperature range
- Asynchronous random access times of 90/90 ns @ 30 pF
- Synchronous random access times of 106/120 ns @ 30 pF
Burst length
- Continuous linear burst
Power dissipation (typical values, 8 bits switching, CL = 30 pF)
- Burst Mode Read: 25 mA
- Simultaneous Operation: 40 mA
- Program/Erase: 15 mA
- Standby mode: 0.2 A
Sector Architecture
- Eight 4 Kword sectors and one hundred twenty-seven 32 Kword sectors
- Bank A contains the eight 4 Kword sectors and thirty-one 32 Kword sectors
- Bank B contains ninety-six 32 Kword sectors
Sector Protection
- Software command sector locking
- WP# protects the last two boot sectors
- All sectors locked when VPP = VIL
Handshaking feature
- Provides host system with minimum possible latency by monitoring RDY
Software command set compatible with JEDEC 42.4 standards
- Backwards compatible with Am29F and Am29LV families
Minimum 1 million erase cycle guarantee per sector
20-year data retention at 125°C
- Reliable operation for the life of the system
  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
Data# Polling and toggle bits
- Provides a software method of detecting program and erase operation completion
Erase Suspend/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
Hardware reset input (RESET#)
- Hardware method to reset the device for reading array data
CMOS compatible inputs, CMOS compatible outputs
Low VCC write inhibit
48-Ball FBGA package

Description

The Am29BDS643D is a 64 Mbit, 1.8 Volt-only, simultaneous Read/Write, Burst Mode Flash memory device, organized as 4,194,304 words of 16 bits each. This device uses a single VCC of 1.7 to 1.9 V to read, program, and erase the memory array. A 12.0-volt VPP may be used for faster program performance if desired. The device can also be programmed in standard EPROM programmers.

At 40 MHz, the Am29BDS643D provides a burst access of 20 ns at 30 pF with initial access times of 120 ns at 30 pF. At 54 MHz, the Am29BDS643 provides a burst access of 13.5 ns at 30 pF with initial access times of 106 ns at 30 pF. The device operates within the industrial temperature range of 40°C to +85°C. The device is offered in the 48-ball FBGA package.
