INTRODUCTION
Sharp’s LH28F016SA 16M Flash Memory is a revolutionary architecture which enables the design of truly mobile, high performance, personal computing and
communication products. With innovative capabilities,
5 V single v oltage operation and very high read/write performance, the LH28F016SA is also the ideal choice for
designing embedded mass storage flash memory systems.
The LH28F016SA is a v ery high density , highest performance non-volatile read/write solution for solid-state
storage applications. Its symmetrically blocked architecture (100% compatible with the LH28F008SA 8M
Flash memory), extended cycling, low power 3.3 V
operation, very fast write and read performance and
selective bloc k locking provide a highly fle xible memory
component suitable for high density memory cards.
Resident Flash Arrays and PCMCIA-ATA Flash Drives.
The LH28F016SA’s dual read voltage enables the
design of memory cards which can interchangeably be
read/written in 3.3 V and 5.0 V systems. Its x8/x16
architecture allows the optimization of memory to processor interface. The flexible block locking option
enables bundling of executable application software in
a Resident Flash Array or memory card. Manuf actured
on Sharp’s 0.55 µm ETOX™ process technology, the
ERASE/WRITE POWER SUPPLY: For erasing memory array blocks or writing
words/bytes/pages into the flash array.
DEVICE POWER SUPPLY (3.3 V ±0.3 V, 5.0 V ±0.5 V): Do not leave any
power pins floating.
NO CONNECT: No internal connection to die, lead may be driven or left floating.
DESCRIPTION
The LH28F016SA is a high performance 16M
(16,777,216 bit) block erasable non-volatile random
access memory organized as either 1M × 16 or 2M × 8.
The LH28F016SA includes thirty-two 64K (65,536)
blocks or thirty-two 32-KW (32,768) blocks. A chip
memory map is shown in Figure 3.
The implementation of a new architecture, with many
enhanced features, will improve the device operating
characteristics and results in greater product reliability
and ease of use.
Among the significant enhancements of the
LH28F016SA:
• 3.3 V Low Power Capability
• Improved Write Performance
• Dedicated Block Write/Erase Protection
A 3/5» input pin reconfigures the device internally for
optimized 3.3 V or 5.0 V read/write operation.
The LH28F016SA will be available in a 56-pin,
1.2 mm thick × 14 mm × 20 mm TSOP (Type I) package. This f orm factor and pinout allow f or very high board
layout densities.
LH28F016SA is the most cost-effective, high-density
3.3 V flash memory.

Page 5
16M (1M × 16, 2M × 8) Flash MemoryLH28F016SA
A Command User Interface (CUI) serves as the system interface between the microprocessor or
microcontroller and the internal memory operation.
Internal Algorithm Automation allows Byte/Word
Writes and Block Erase operations to be executed
using a Two-Write command sequence to the CUI in
the same way as the LH28F008SA 8M Flash memory.
A Superset of commands have been added to the
basic LH28F008SA command-set to achieve higher
write performance and provide additional capabilities.
These new commands and features include:
• Page Buffer Writes to Flash
• Command Queuing Capability
• Automatic Data Writes During Erase
• Software Locking of Memory Blocks
• T w o-Byte Successive Writes in 8-bit Systems
• Erase All Unlocked Blocks
Writing of memory data is performed in either byte or
word increments typically within 6 µs, a 33% improvement over the LH28F008SA. A Block Erase operation
erases one of the 32 blocks in typically 0.6 seconds,
independent of the other blocks, which is about 65%
improvement ov er the LH28F008SA.
The LH28F016SA incorporates two Page Buffers of
256 Bytes (128 W ords) each to allow page data writes.
This feature can improve a system write performance
over pre vious flash memory de vices.
All operations are started by a sequence of Write
commands to the device. Three Status Registers (described in detail later) and a RY»/BY» output pin provide
information on the progress of the requested operation.
While the LH28F008SA requires an operation to complete before the next operation can be requested, the
LH28F016SA allows queuing of the next oper ation while
the memory executes the current operation. This eliminates system overhead when writing sev eral b ytes in a
row to the array or erasing several blocks at the same
time. The LH28F016SA can also perform write operations to one block of memory while performing erase of
another block.
The LH28F016SA contains three types of Status
Registers to accomplish various functions:
• A Compatible Status Register (CSR) which is 100%
compatible with the LH28F008SA Flash memory’s
Status Register. This register , when used alone, provides a straightforward upgrade capability to the
LH28F016SA from a LH28F008SA-based design.
• A Global Status Register (GSR) which informs the
system of command Queue status, Page Buff er status, and over all Write State Machine (WSM) status.
• 32 Block Status Registers (BSRs) which provide
block-specific status inf ormation such as the block
lock-bit status.
The GSR and BSR memory maps for Byte-Wide and
Word-Wide modes are shown in Figures 4 and 5.
The LH28F016SA incorporates an open drain
RY»/BY» outpin. This feature allows the user to OR-tie
many RY»/BY» pins together in a multiple memory configuration such as a Resident Flash Array.
The LH28F016SA also incorporates a dual chipenable function with two input pins, CE »0 and CE»1. These
pins have exactly the same functionality as the regular
chip-enable pin CE» on the LH28F008SA. F or minimum
chip designs, CE»1 may be tied to ground and use CE»
as the chip enable input. The LH28F016SA uses the
logical combination of these two signals to enable or
disable the entire chip. Both CE»0 and CE»1 must be active low to enable the de vice and if either one becomes
inactive, the chip will be disabled. This feature, along
with the open drain RY»/BY» pin, allows the system de-
signer to reduce the number of control pins used in a
large array of 16M de vices .
The BY»TE» pin allows either x8 or x16 read/writes to
the LH28F016SA. BY»TE» at logic low selects 8-bit mode
with address A0 selecting between low byte and high
byte. On the other hand, BY»TE» at logic high enables
16-bit operation with address A1 becoming the lowest
order address and address A0 is not used (don’t care).
A block diagram is shown in Figure 2.
The LH28F016SA is specified for a maximum access
time of each version, as follo ws:
0
The LH28F016SA provides user-selectable block
locking to protect code or data such as Device Driv ers,
PCMCIA card information, ROM-Executable O/S or
Application Code. Each block has an associated nonvolatile lock-bit which determines the lock status of the
block. In addition, the LH28F016SA has a master Write
Protect pin (WP
memory blocks whose lock-bits are set.
MEMORY MAPThe LH28F016SA incorporates an Automatic P ow er
Saving (APS) feature which substantially reduces the
active current when the device is in static mode of
operation (addresses not switching).
In APS mode, the typical ICC current is 2 mA at
5.0 V (1 mA at 3.3 V).
A Deep Power-Down mode of operation is invoked
when the RP» (called PWD on the LH28F008SA) pin
transitions low . This mode brings the device pow er consumption to less than 5 µA, typically , and provides additional write protection by acting as a device reset pin
during power transitions. A reset time of 400 ns
(VCC = 5.0 V ± 0.25 V system) is required from RP»
switching high until outputs are again valid. In the Deep
Power-Down state, the WSM is reset (any current
operation will abort) and the CSR, GSR and BSR registers are cleared.
A CMOS Standby mode of operation is enabled when
either CE»0 or CE»1 transitions high and RP» sta ys high with
all input control pins at CMOS levels. In this mode, the
device typically dra ws an ICC standby current of 10 µA.
NOTE: In word-wide mode A0 don't care, address values
are ignored A0.

NOTES:
1. X can be VIH or VIL for address or control pins except for RY»/BY», which is either VOL or VOH.
2. RY»/BY» output is open drain. When the WSM is ready, Erase is suspended or the device is in deep power-down mode,
RY»/BY» will be at VOH if it is tied to VCC through a resistor. When the RY»/BY» at VOH is independent of OE
operation is in progress.
3. RP» at GND ± 0.2 V ensures the lowest deep power-down current.
4. A0 and A1 at VIL provide manufacturer ID codes in x8 and x16 modes respectively. A0 and A1, at VIH provide device ID
codes in x8 and x16 modes respectively. All other addresses are set to zero.
5. Commands for different Erase operations, Data Write operations of Lock-Block operations can only be successfully completed when VPP = V
6. While the WSM is running, RY»/BY» in Level-Mode (default) stays at VOL until all operations are complete. RY»/BY» goes to
VOH when the WSM is not busy or in erase suspend mode.
7. RY»/BY» may be at VOL while the WSM is busy performing various operations. For example, a status register read during a
write operation.

2. The CSR is automatically available after device enters Data Write, Erase or Suspend operations.
3. Clears CSR.3, CSR.4, and CSR.5. Also clears GSR.5 and all BSR.5 and BSR.2 bits. See Status register definitions.
4. While device performs Block Erase, if you issue Erase Suspend command (B0H), be sure to confirm ESS (Erase-Suspend-Status) is
set to 1 on compatible status register. In the case, ESS bit was not set to 1, also completed the Erase (ESS = 0, WASM = 1), be sure
to issue Resume command (D0H) after completed next Erase command. Beside, when the Erase Suspend command is issued,while
the device is not in Erase, be sure to issue Resume command (D0H) after the next erase completed. When you use Erase Suspend/
Resume command, we recommend to issue serial Block Erase command (20H, D0H) and Resume command (D0H). (Refer to Performance Enhancement Command Bus Definitions.)

NOTES:
1. RA can be the GSR address or any BSR address. See Figure 4 and 5 for Extended Status Register Memory Maps.
2. Upon device power-up, all BSR lock-bits come up locked. The Uploaded Status Bits command must be written to reflect the actual
lock-bit status.
3. A0 is automatically complemented to load second byte of data. BY»TE
first: A0 = 0 looks at the WDL/BCL, A0 = 1 looks at the WDH/BCH.
4. BCH/WCH must be at 00H for this product because of the 256-Byte (128 Word) Page Buffer size and to avoid writing the Page Buffer
contents into more than one 256-Byte segment within an array block. They are simply shown for future Page Buffer expandability.
5. In x16 mode, only the lower byte DQ0 - DQ7 is used for WCL and WCH. The upper byte DQ8 - DQ15 is a don’t care.
6. PA and PD (Whose count is given in cycles 2 and 3) are supplied starting in the 4th cycle which is not shown.
7. This command allows the user to swap between available Page Buffers (0 or 1).
8. These commands reconfigure RY»/BY» output to one of two pulse-modes or enable and disable the RY»/BY» function.
9. Write address, WA, is the Destination address in the flash array which must match the Source address in the Page Buffer. Refer to the
LH28F016SU User’s Manual.
10. BCL = 00H corresponds to a Byte count of 1. Similarly, WCL = 00H corresponds to a Word count of 1.
11. Unless you issue erase suspend command, it is not necessary to input D0H on third bus cycle.

CE» is defined as the latter of CE»0 or CE»1 going Low or the first of CE»0 or CE»1 going High.
1. Read timing during write and erase are the same as for normal read.
2. Refer to command definition tables for valid address and data values.
3. Sampled, but not 100% tested.
4. Write/Erase durations are measured to valid Status Register (CSR) Data.
5. Word/Byte write operations are typically performed with 1 Programming Pulse.
6. Address and Data are latched on the rising edge of CE» for all Command Write Operations.
