S29AL016J
General Description
The S29AL016J is a 16 Mbit, 3.0 Volt-only Flash memory organized as 2,097,152 bytes or 1,048,576 words. The device is offered in
48-ball Fine-pitch BGA (0.8 mm pitch), 64-ball Fortified BGA (1.0 mm pitch) and 48-pin TSOP packages. The word-wide data (x16)
appears on DQ15–DQ0; the byte-wide (x8) data appears on DQ7–DQ0. This device is designed to be programmed in-system with
the standard system 3.0 volt V
CC
supply. A 12.0 V V
PP
or 5.0 V
CC
are not required for write or erase operations. The device can also
be programmed in standard EPROM programmers.
The device offers access time of 55 ns allowing high speed microprocessors to operate without wait states. To eliminate bus
contention the device has separate chip enable (CE#), write enable (WE#) and output enable (OE#) controls.
The device requires only a
single 3.0 volt power supply
for both read and write functions. Internally generated and regulated
voltages are provided for the program and erase operations.
The S29AL016J is entirely command set compatible with the
JEDEC single-power-supply Flash standard.
Commands are written
to the command register using standard microprocessor write timings. Register contents serve as input to an internal state-machine
that controls the erase and programming circuitry. Write cycles also internally latch addresses and data needed for the programming
and erase operations. Reading data out of the device is similar to reading from other Flash or EPROM devices.
Device programming occurs by executing the program command sequence. This initiates the
Embedded Program
algorithm—an
internal algorithm that automatically times the program pulse widths and verifies proper cell margin. The
Unlock Bypass
mode
facilitates faster programming times by requiring only two write cycles to program data instead of four.
Device erasure occurs by executing the erase command sequence. This initiates the
Embedded Erase
algorithm—an internal
algorithm that automatically preprograms the array (if it is not already programmed) before executing the erase operation. During
erase, the device automatically times the erase pulse widths and verifies proper cell margin.
The host system can detect whether a program or erase operation is complete by observing the RY/BY# pin, or by reading the DQ7
(Data# Polling) and DQ6 (toggle)
status bits.
After a program or erase cycle has been completed, the device is ready to read array
data or accept another command.
The
sector erase architecture
allows memory sectors to be erased and reprogrammed without affecting the data contents of other
sectors. The device is fully erased when shipped from the factory.
Hardware data protection
measures include a low V
CC
detector that automatically inhibits write operations during power
transitions. The
hardware sector protection
feature disables both program and erase operations in any combination of the sectors
of memory. This can be achieved in-system or via programming equipment.
The
Erase Suspend/Erase Resume
feature enables the user to put erase on hold for any period of time to read data from, or
program data to, any sector that is not selected for erasure. True background erase can thus be achieved.
The
hardware RESET# pin
terminates any operation in progress and resets the internal state machine to reading array data. The
RESET# pin may be tied to the system reset circuitry. A system reset would thus also reset the device, enabling the system
microprocessor to read the boot-up firmware from the Flash memory.
The device offers two power-saving features. When addresses have been stable for a specified amount of time, the device enters
the
automatic sleep mode.
The system can also place the device into the
standby mode.
Power consumption is greatly reduced in
both these modes.
Cypress combines years of flash memory manufacturing experience to produce the highest levels of quality, reliability and cost
effectiveness. The device electrically erases all bits within a sector simultaneously via Fowler-Nordheim tunneling. The data is
programmed using hot electron injection.
