DESCRIPTION
The M59DR008 is an 8 Mbit non-volatile Flash
memory that may be erased electrically at block
level and programmed in-system on a Word-by-
Word basis using a 1.65V to 2.2V V
DD
supply for
the circuitry. For Program and Erase operations
the necessary high voltages are generated inter-
nally. The device supports asynchronous page
mode from all the blocks of the memory array.
The array matrix organization allows each block to
be erased and reprogrammed without affecting
other blocks. All blocks are protected against pro-
gramming and erase at Power Up. Blocks can be
unprotected to make changes in the application
and then reprotected.
Instructions for Read/Reset, Auto Select, Write
Configuration Register, Programming, Block
Erase, Bank Erase, Erase Suspend, Erase Re-
sume, Block Protect, Block Unprotect, Block Lock-
ing, CFI Query, are written to the memory through
a Command Interface using standard micropro-
cessor write timings.
The device is offered in TSOP48 (12 x 20 mm)
and in TFBGA48 (0.75 mm pitch) packages and it
is supplied with all the bits erased (set to ‘1’).
Organization
The M59DR008 is organized as 512Kb x16 bits.
A0-A18 are the address lines, DQ0-DQ15 are the
Data Input/Output. Memory control is provided by
Chip Enable E, Output Enable G and Write Enable
W inputs.
Reset RP is used to reset all the memory circuitry
and to set the chip in power down mode if this
function is enabled by a proper setting of the Con-
figuration Register. Erase and Program operations
are controlled by an internal Program/Erase Con-
troller (P/E.C.). Status Register data output on
DQ7 provides a Data Polling signal, DQ6 and DQ2
provide Toggle signals and DQ5 provides error bit
to indicate the state of the P/E.C operations.
Memory Blocks
The device features asymmetrically blocked archi-
tecture. M59DR008 has an array of 23 blocks and
is divided into two banks A and B, providing Dual
Bank operations. While programming or erasing in
Bank A, read operations are possible into Bank B
or vice versa. The memory also features an erase
suspend allowing to read or program in another
block within the same bank. Once suspended the
erase can be resumed. The Bank Size and Sector-
ization are summarized in Table 7. Parameter
Blocks are located at the top of the memory ad-
dress space for the M59DR008E, and at the bot-
tom for the M59DR008F. The memory maps are
shown in Tables 3, 4, 5 and 6.
The Program and Erase operations are managed
automatically by the P/E.C. Block protection
against Program or Erase provides additional data
security. All blocks are protected at Power Up. In-
structions are provided to protect or unprotect any
block in the application. A second register locks
the protection status while WP is low (see Block
Locking description). The Reset command does
not affect the configuration of unprotected blocks
and the Configuration Register status.

SIGNAL DESCRIPTIONS
See Figure 1 and Table 1.
Address Inputs (A0-A18).
The address inputs
for the memory array are latched during a write op-
eration on the falling edge of Chip Enable E or
Write Enable W, whichever occurs last.
Data Input/Output (DQ0-DQ15).
The Input is
data to be programmed in the memory array or a
command to be written to the Command Interface
(C.I.) Both input data and commands are latched
on the rising edge of Write Enable W. The Ouput
is data from the Memory Array, the Common Flash
Interface, the Electronic Signature Manufacturer
or Device codes, the Block Protection status, the
Configuration Register status or the Status Regis-
ter Data Polling bit DQ7, the Toggle Bits DQ6 and
DQ2, the Error bit DQ5. The data bus is high im-
pedance when the chip is deselected, Output En-
able G is at V
IH
, or RP is at V
IL
.
Chip Enable (E).
The Chip Enable input acti-
vates the memory control logic, input buffers, de-
coders and sense amplifiers. E at V
IH
deselects
the memory and reduces the power consumption
to the standby level. E can also be used to control
writing to the command register and to the memo-
ry array, while W remains at V
IL
.
Output Enable (G).
The Output Enable gates the
outputs through the data buffers during a read op-
eration. When G is at V
IH
the outputs are High im-
pedance.
Write Enable (W).
This input controls writing to
the Command Register and Data latches. Data are
latched on the rising edge of W.
Write Protect (WP).
This input gives an addition-
al hardware protection level against program or
erase when pulled at V
IL
, as described in the Block
Lock instruction description.
Reset/Power Down Input (RP).
The RP input
provides hardware reset of the memory (without
affecting the Configuration Register status), and/
or Power Down functions, depending on the Con-
figuration Register status. Reset/Power Down of
the memory is achieved by pulling RP to V
IL
for at
least t
PLPH
. When the reset pulse is given, if the
memory is in Read, Erase Suspend Read or
Standby, it will output new valid data in t
PHQ7V1
af-
ter the rising edge of RP. If the memory is in Erase
or Program modes, the operation will be aborted
and the reset recovery will take a maximum ot
t
PLQ7V
. The memory will recover from Power
Down (when enabled) in t
PHQ7V2
after the rising
edge of RP. See Tables 24, 26 and Figure 10.

DEVICE OPERATIONS
The following operations can be performed using
the appropriate bus cycles: Read Array (Random,
and Page Modes), Write command, Output Dis-
able, Standby, Reset/Power Down and Block
Locking. See Table 8.
Read.
Read operations are used to output the
contents of the Memory Array, the Electronic Sig-
nature, the Status Register, the CFI, the Block
Protection Status or the Configuration Register
status. Read operation of the memory array is per-
formed in asynchronous page mode, that provides
fast access time. Data is internally read and stored
in a page buffer. The page has a size of 4 words
and is addressed by A0-A1 address inputs. Read
operations of the Electronic Signature, the Status
Register, the CFI, the Block Protection Status, the
Configuration Register status and the Security
Code are performed as single asyncronous read
cycles (Random Read). Both Chip Enable E and
Output Enable G must be at V
IL
in order to read the
output of the memory.
Write.
Write operations are used to give Instruc-
tion Commands to the memory or to latch Input
Data to be programmed. A write operation is initi-
ated when Chip Enable E and Write Enable W are
at V
IL
with Output Enable G at V
IH
. Addresses are
latched on the falling edge of W or E whichever oc-
curs last. Commands and Input Data are latched
on the rising edge of W or E whichever occurs first.
Noise pulses of less than 5ns typical on E, W and
G signals do not start a write cycle.
