INTRODUCTION
Sharp’s LH28F016LL 16M Flash Memory is a revolutionary architecture which enables the design of truly
mobile, high performance, personal computing and communication products. With innovative capabilities,
3 V single voltage operation and very high read/write
performance, the LH28F0166LL is also the ideal choice
for designing embedded mass storage flash memory
systems.
The LH28F016LL is very high density, highest performance non-volatile read/write solution for solid-state
storage applications. Its symmetrically blocked architecture (100% compatible with the LH28F016SU 16M
Flash memory), extended cycling, minimum power
2.7 V operation, very fast write and read performance
and selective block locking provide a highly flexible
memory component suitable for battery operation portable equipment such as digital still camera, PDA, cellular phone, and memory card. Its x8/x16 architecture
allows the optimization of memory to processor interface. The flexible block locking option enables bundling
of executable of executable application software in a
Resident Flash Array or memory card. Manufactured
on Sharp’s 0.6 µm ETOX™ process technology, the
LH28F016LL is the most cost-effective, high-density
3 V single power operation flash memory.
DESCRIPTION
The LH28F016LL is a high performance 16M
(16,777,216 bit) block erasable non-volatile random
access memory organized as either 1M × 16 or 2M x 8.
The LH28F016LL 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
LH28F016LL:
•
•
•
•
3 V Write/Erase Operation (3 V VPP)
3 V Low Power Capability
Improved Write Performance
Dedicated Block Write/Erase Protection
The LH28F016LL will be available in a 56-pin,
1.2 mm thick × 14 mm × 20 mm TSOP (Type I) package. This form factor and pinout allow for very high board
layout densities.
A Command User Interface (CUI) serves as the system interface between the microprocessor or
microcontroller and the internal memory operation.
LH28F016LL
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
Two-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 9 µs, a 15% improvement over the LH28F008SA.
Each block can be written and erased a minimum of
100,000 cycles. Systems can achieve 1,000,000 Block
Erase Cycles by providing wear-leveling algorithms and
graceful block retirement. These techniques have
already been employed in many flash file systems and
Hard Disk Drive designs.
The LH28F016LL incorporates two Page Buffers of
256 Bytes (128 Words) each to allow page data writes.
This feature can improve a system write performance
by up to 4.8 times over previous flash memory devices.
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
LH28F016LL allows queuing of the next operation while
the memory executes the current operation. This eliminates system overhead when writing several bytes in a
row to the array or erasing several blocks at the same
time. The LH28F016LL can also perform write operations to one block of memory while performing erase of
another block.
The LH28F016LL provides user-selectable block
locking to protect code or data such as Device Drivers,
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 LH28F016LL has a master Write
Protect pin (WP ») which prevents any modifications to
memory blocks whose lock-bits are set.

LH28F016LL
The LH28F016LL 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
LH28F016LL from a LH28F008SA-based design.
• A Global Status Register (GSR) which informs
the system of command Queue status. Page
Buffer status, and overall Write Status Machine
(WSM) status.
• 32 Block Status Registers (BSRs) which provide
block-specific status information 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 LH28F016LL incorporates an open drain
RY »/BY » output pin. This feature allows the user to ORtie many RY /» BY » pins together in a multiple memory configuration such as a Resident Flash Array.
The LH28F016LL also incorporates a dual chipenable function with two input pins, CE 0» and CE 1» . These
pins have exactly the same functionality as the regulary
chip-enable pin CE » on the LH28F008SA. For minimum
chip designs, CE »1 may be tied to ground and use CE »0
as the chip enable input. The LH28F016LL 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 device and if either one becomes inactive, the chip will be disabled. This feature, along with
the open drain RY »/BY » pin, allows the system designer
to reduce the number of control pins used in a large
array of 16M devices.
The BY T
» E » pin allows either x8 or x16 read/writes to
the LH28F016LL. BY T
» E » at logic low selects 8-bit mode
with address A0 selecting between low byte and high
byte. On the other hand, BY T
» E » 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 device diagram is shown in Figure 1.
The LH28F016LL is specified for a maximum access
time (tACC)150 ns, in operating voltage 2.7 V to 3.6 V
and in operating temperature 0°C to +70°C.
The LH28F016LL incorporates an Automatic Power
Saving (APS) feature which substantially reduces the
active current when the device is in static mode of
operation (address not switching).

In APS mode, the typical ICC current is 1 mA at 3.0 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 power 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 480 ns is required from RP » switching high until outputs are again
valid. In the Deep Power-Down state, the WSM is reset
6
(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 » stays high
with all input control pins at CMOS levels. In this mode,
the device typically draws an ICC standby current of
10 µA.

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

NOTES:
1. RA can be the GSR address or any BSR address. See Figure 4.1 and 4.2 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 T
» E » must be at VIL. A0 value determines which WD/BC is supplied
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 - DQ 7 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.

2. If DWS and ES are set to ‘1’ during an erase attempt, an
improper command sequence was entered. Clear the CSR
and attempt the operation again.
3. The VPPS bit, unlike an A/D converter, does not provide
continuous indication of VPP level. The WSM interrogates
VPP’s level only after the Data-Write or Erase command
sequences have been entered, and informs the system if
VPP has not been switched on. VPPS is not guaranteed to
report accurate feedback between VPPL and VPPH.
4. CSR.2 - CSR.0 = Reserved for future enhancements.
These bits are reserved for future use and should be

cross point definitions. Each timing parameter consists of 5 characters. Some common examples are defined below:
tCE
tELQV
time (t) from CE » (E) going low (L) to the outputs (Q) becoming valid (V)
tOE
tGLQV
time (t) from OE » (G) going low (L) to the outputs (Q) becoming valid (V)
tACC tAVQV
time (t) from address (A) valid (V) to the outputs (Q) becoming valid (V)
tAS
tAVWH time (t) from address (A) valid (V) to WE » (W) going high (H)
tDH
tWHDX time (t) from WE » (W) going high (H) to when the data (D) can become undefined (X)
