32-bit RISC Microprocessor - TX19 Family
TMP19A64F20AXBG
1.
Overview and Features
The TX19 family is a high-performance 32-bit RISC processor series that TOSHIBA originally developed by
integrating the MIPS16TMASE (Application Specific Extension), which is an extended instruction set of high code
efficiency.
TMP19A64 is a 32-bit RISC microprocessor with a TX19A processor core and various peripheral functions
integrated into one package. It can operate at low voltage with low power consumption.
Features of TMP19A64 are as follows:
(1) TX19A processor core
1)
2)
Improved code efficiency and operating performance have been realized through the use of two ISA
(Instruction Set Architecture) modes - 16- and 32-bit ISA modes.
•
The 16-bit ISA mode instructions are compatible with the MIPS16 TMASE instructions of superior
code efficiency at the object level.
•
The 32-bit ISA mode instructions are compatible with the TX39 instructions of superior operating
performance at the object level.
Both high performance and low power consumption have been achieved.

Note 1: For BUSMD, ENDIAN and BOOT pins, the state designated for each pin ("H" or "L"
level) must be maintained during one system clock before and after the rising of a
reset signal. The reset pin must always be in a stable state at both "L" and "H" levels.
Note 2: For DREQ2, DACK2, DREQ3 and DACK3, it is necessary to go to the port function
register and to select one port from two groups of ports, PF3 to PF6 and PJ0 to PJ3.
Two ports cannot be operated simultaneously to use the same function.
Likewise, for pins INT0 through INT4, one port must be selected from ports PI0 to PI4
and ports PO0 to PO4.

Flash Memory Operation
This section describes the hardware configuration and operation of the flash memory. The feature of this device
is that the internal ROM of TMP19A64C1DXBG is replaced by an internal flash memory. Other configurations
and functions of the device remain the same as with TMP19A64C1DXBG. Please refer to the
TMP19A64C1DXBG data sheet for functions not described in this section.
3.1
Flash Memory
3.1.1
Features
1)
Memory capacity
The TMP19A64F20AXBG device contains two 8M bits (1MB) of flash memory capacity. The
memory area consists of 4 independent memory blocks (128 kB × 16) to enable independent write
access to each block. When the CPU is to access the internal flash memory, 32-bit data bus width
is used.

The above values are theoretical values not including data transfer time.
The write time per chip depends on the write method to be used by the user.
Programming method
Two modes are available, i.e., the onboard programming mode to allow programming on the
user's board and the writer mode to program the device using an EPROM writer.
• Onboard programming mode
1) User boot mode
The user's original rewriting method can be supported.
2) Single boot mode
The rewriting method to use serial data transfer
(Toshiba's unique method) can be supported.
• Writer mode
Use of a general purpose EPROM writer is supported.
5)
Rewriting method
The flash memory included in this device is generally compliant with the applicable JEDEC
standards except for some specific functions. Therefore, if the user is currently using an external
flash memory device, it is easy to implement the functions into this device. Furthermore, the user
is not required to build his/her own programs to realize complicated write and erase functions
because such functions are automatically performed using the circuits already built-in the flash
memory chip.
This device is also implemented with a read-security function to inhibit reading flash memory
data from any external writer device. On the other hand, rewrite protection is available only
through command-based software programming; any hardware setting method to apply +12VDC
is not supported. The above described security function is automatically enabled when all the four
area are configured for protection. When the user removes protection, the internal data is
automatically erased before the protection is actually removed.

Operation Mode
This device has four operation modes including the mode not to use the internal flash memory.
Table 3.2.1.1 Operation Modes
Operation mode
Single chip mode
Operation details
After reset is cleared, it starts up from the internal flash memory.
Normal mode
In this operation mode, two different modes, i.e., the mode to execute user application programs
and the mode to rewrite the flash memory onboard the user’s card, are defined. The former is
referred to as "normal mode" and the latter "user boot mode."
User boot mode
The user can uniquely configure the system to switch between these two modes.
For example, the user can freely design the system such that the normal mode is selected when the
port "00" is set to "1" and the user boot mode is selected when it is set to "0."
The user should prepare a routine as part of the application program to make the decision on the
selection of the modes.
After reset is cleared, it starts up from the internal Boot ROM (Mask ROM). In the Boot ROM, an
algorithm to enable flash memory rewriting on the user’s set through the serial port of this device
is programmed. By connecting to an external host computer through the serial port, the internal
flash memory can be programmed by transferring data in accordance with predefined protocols.
This mode allows use of a general purpose EPROM writer to rewrite the internal flash memory.
Please use a special program adaptor and an EPROM writer that are recommended for use.
Single boot mode
Writer mode
Among the flash memory operation modes listed in the above table, the user boot mode, single boot mode, and
writer mode are programmable modes. These two modes, the User Boot mode and the Single Boot mode, are
referred to as "Onboard Programming" modes where onboard rewriting of internal flash memory can be made
on the user's card.
TMP19A64(rev1.1)-3-3
TMP19A64F20AXBG
Either the single chip, single boot, or writer operation mode can be selected by externally setting the levels of
the BW0, BW1, and BOOT input pins while the device is in the reset state.
Except for the case of the writer mode, the CPU starts operation in the selected operation mode when the reset
condition is removed after the pin levels are set. The writer mode is used with RESET set to "0". Be sure not to
change the levels during operation once the mode is selected. The mode setting method and the mode transition

3.2.1
Reset Operation
To reset the device, ensure that the power supply voltage is within the operating voltage range, that the
internal oscillator has been stabilized, and that the RESET input is held at "0" for a minimum duration of
12 system clocks (1.8 μs with 54 MHz operation; the "1/8" clock gear mode is applied after reset).
(Note 1) Regarding power-on reset of devices with internal flash memory;
For devices with internal flash memory, it is necessary to apply "0" to the RESET inputs
upon power on for a minimum duration of 60 microseconds regardless of the operating
frequency.
During this period, each protection bit, to be described later, is locked in the state it is
written regardless of the state it ought to be. The original values of protection bits can be
checked by reading the register FLCS <BLPRO 3:0> after the power on reset operation is
normally terminated.
(Note 2) While flash programming is in progress, at least 0.5 microseconds of reset period is
required regardless of the system clock frequency.

3.2.2
DSU (EJTAG) - PROBE Interface
This interface is used when the DSU probe is used in debugging. This is the dedicated interface for
connection to the DSU probe. Please refer to the operation manual for the DSU probe you are going to use
for details of debugging procedures to use the DSU probe. Here, the function to enable/disable the DSU
probe in the DSU (EJTAG) mode is described.
1)
Security function
This device allows use of an on-board DSU probe for debugging. To facilitate this, the device is
implemented with a security measure to prevent easy reading of the internal flash memory by a third
party other than the authorized user. By enabling the security function, it becomes impossible to read
the internal flash memory from a DSU probe. Use this function together with the security function of
the internal flash memory itself as described later.
2)
DSU probe enable/disable function
This device allows use of on-board DSU probes for debugging operations. To facilitate this, the device
is implemented with the "DSU probe inhibit" function (hereafter referred to as the "DSU inhibit"
function) to prevent easy reading of the internal flash memory by a third party other than the
authorized user. By enabling the DSU inhibit function, use of any DSU probe becomes impossible.
3)
DSU enable (Enables use of DSU probes for debugging)
In order to prevent the DSU inhibit function from being accidentally removed by system runaway, etc.,
the method to cancel the inhibit function requires a double action operation so it is necessary to set
DSU security mode register DSUSEC1<DSUOFF> to "0" and also write the security code
"0x0000_00C5" to the DSU security control register DSUSEC2 to cancel the function. Then,
debugging to use a DSU probe is allowed. While power to the device is still applied, setting
DSUSEC1<DSUOFF> to "1" and writing "0x0000_00C5" to the DSUSEC2 register will enable the
security function again.

3.3
On-board Programming of Flash Memory (Rewrite/Erase)
In on-board programming, the CPU is to execute software commands for rewriting or erasing the flash memory.
The rewrite/erase control program should be prepared by the user beforehand. Because the flash memory
content cannot be read while it is being written or erased, it is necessary to run the rewrite/erase program from
the internal RAM or from an external memory device after shifting to the user boot mode. In this section, flash
memory addresses are represented in virtual addresses unless otherwise noted.
3.4
Flash Memory
Except for some functions, writing and erasing flash memory data are in accordance with the standard JEDEC
commands. In writing or erasing, use the SW command of the CPU to enter commands to the flash memory.
Once the command is entered, the actual write or erase operation is automatically performed internally.
Table 3.4.1.1 Flash Memory Functions
Major functions
Automatic page program
Automatic chip erase
Automatic block erase
Write protect
Security function
Description
Writes data automatically (in 128 word blocks).
Automatically erases the flash memory area one chip at a time (1 MB at a time).
Erases a selected block automatically (128 kB at a time).
The write or erase function can be individually inhibited for each area (of 512 kB). When all
areas are set for protection, the security function is automatically enabled.
A security function is implemented to inhibit reading from the flash memory when the
device is in the writer mode. By setting protection to all the four areas, the security function
is enabled. In order to disable the security function, it is necessary to cancel write protection
when the entire flash memory is automatically erased.
Note that addressing of operation commands is different from the case of standard commands due to the specific
interface arrangements with the CPU as detailed operation of the user boot mode and RAM transfer mode is
described later. Also note that the flash memory is written in 32-bit blocks. So, 32-bit (word) data transfer
commands must be used in writing the flash memory.

Fig. 3.4.1.2 Block Configuration of Flash Memory
TMP19A64(rev1.1)-3-8
TMP19A64F20AXBG
(2) Basic operation
Generally speaking, this flash memory device has the following two operation modes:
•
The mode to read memory data (Read mode)
•
The mode to automatically erase or rewrite memory data (Automatic operation)
Transition to the automatic mode is made by executing a command sequence while it is in the memory
read mode. In the automatic operation mode, flash memory data cannot be read and any commands
stored in the flash memory cannot be executed. During automatic operation, be sure not to cause any
exceptions other than debug exceptions and reset while a DSU probe is connected. Any interrupt or
exception generation cannot set the device to the read mode except when a hardware reset is generated.
1)
Read
When data is to be read, the flash memory must be set to the read mode. The flash memory will
be set to the read mode immediately after power is applied, when CPU reset is removed, or when
an automatic operation is normally terminated. In order to return to the read mode from other
modes or after an automatic operation has been abnormally terminated, either the Read/reset
command (a software command to be described later) or a hardware reset is used. The device
must also be in the read mode when any command written on the flash memory is to be executed.
•
Read/reset command and Read command (software reset)
When an automatic operation is abnormally terminated, the flash memory cannot return to the
read mode by itself (When FLCS<RDY/BSY> = 0, data read from the flash memory is
undefined.) In this case, the Read/reset command can be used to return the flash memory to
the read mode. Also, when a command that has not been completely written has to be
canceled, the Read/reset command must be used to return to the read mode. The Read
command is used to return to the read mode after executing the SW command to write the
data "0x0000_00F0" to two arbitrary addresses 0x001x_xxxx and 0x000x_xxxx of the flash
memory.
•
2)
With the Read/reset command, the device is returned to the read mode after completing the
third bus write cycle.
Command write
This flash memory uses the command control method. Commands are executed by executing a
command sequence to the flash memory. The flash memory executes automatic operation
commands according to the address and data combinations applied (refer to Command Sequence).
If it is desired to cancel a command write operation already in progress or when any incorrect
command sequence has been entered, the Read/reset command is to be executed. Then, the flash
memory will terminate the command execution and return to the read mode.
Also, when issuing a command, the address [20:19] must be fixed to either "1" or "0" in order to
enable a decision to select either chip 0 or 1.
While commands are generally comprised of several bus cycles, the operation to apply the SW
command to the flash memory is called "bus write cycle." The bus write cycles are to be in a
specific sequential order and the flash memory will perform an automatic operation when the
sequence of the bus write cycle data and address of a command write operation is in accordance
with a predefined specific sequence. If any bus write cycle does not follow a predefined
command write sequence, the flash memory will terminate the command execution and return to
the read mode. The address [31:21] in each bus write cycle should be the virtual address [31:21]
of command execution. It will be explained later for the address bits [20:8].
TMP19A64(rev1.1)-3-9
TMP19A64F20AXBG
(Note 1) Command sequences are executed from outside the flash memory area.
(Note 2) The interval between bus write cycles for this device must be 15 system clock cycles or
longer. The command sequencer in the flash memory device requires a certain time period to
recognize a bus write cycle. If more than one bus write cycles are executed within this time
period, normal operation cannot be expected. For adjusting the applicable bus write cycle
interval using a software timer to be operated at the operating frequency, use the section 10)
"ID-Read" to check for the appropriateness.
(Note 3) Between the bus write cycles, never use any load command (such as LW, LH, or LB) to the
flash memory or perform a DMA transmission by specifying the flash area as the source
address. Also, don't execute a Jump command to the flash memory. While a command
sequence is being executed, don't generate any interrupt such as maskable interrupts (except
debug exceptions when a DSU probe is connected).
If such an operation is made, it can result in an unexpected read access to the flash memory
and the command sequencer may not be able to correctly recognize the command. While it
could cause an abnormal termination of the command sequence, it is also possible that the
written command is incorrectly recognized.
(Note 4) The SYNC command must be executed immediately after the SW command for each bus
write cycle.
(Note 5) For the command sequencer to recognize a command, the device must be in the read mode
prior to executing the command. Be sure to check before the first bus write cycle that the
FLCS[0] RDY/BSY bit is set to "1." It is recommended to subsequently execute a Read
command.
(Note 6) Upon issuing a command, if any address or data is incorrectly written, be sure to perform a
system reset operation or issue a reset command (for Chip 0 and Chip 1) to return to the read
mode again.
3)
Reset
Hardware reset
The flash memory has a reset input as the memory block and it is connected to the CPU reset
signal. Therefore, when the RESET input pin of this device is set to VIL or when the CPU is reset
due to any overflow of the watch dog timer, the flash memory will return to the read mode
terminating any automatic operation that may be in progress. The CPU reset is also used in
returning to the read mode when an automatic operation is abnormally terminated or when any
mode set by a command is to be canceled. It should also be noted that applying a hardware reset
during an automatic operation can result in incorrect rewriting of data. In such a case, be sure to
perform the rewriting again.
Refer to Section 3.1 "Reset Operation" for CPU reset operations. After a given reset input, the
CPU will read the reset vector data from the flash memory and starts operation after the reset is
removed.
4)
Automatic Page Programming
Writing to a flash memory device is to make "1" data cells to "0" data cells. Any "0" data cell
cannot be changed to a "1" data cell. For making "0" data cells to "1" data cells, it is necessary to
perform an erase operation.
The automatic page programming function of this device writes data in 128 word blocks. A 128
word block is defined by a same [31:9] address and it starts from the address [8:0] = 0 and ends at
the address [8:0] = 0x1FF. This programming unit is hereafter referred to as a "page."
TMP19A64(rev1.1)-3-10
TMP19A64F20AXBG
Writing to data cells is automatically performed by an internal sequencer and no external control
by the CPU is required. The state of automatic page programming (whether it is in writing
operation or not) can be checked by the FLCS <RDY/BSY> register.
Also, any new command sequence is not accepted while it is in the automatic page programming
mode. If it is desired to interrupt the automatic page programming, use the hardware reset
function. If the operation is stopped by a hardware reset operation, it is necessary to once erase
the page and then perform the automatic page programming again because writing to the page has
not been normally terminated.
The automatic page programming operation is allowed only once for a page already erased. No
programming can be performed twice or more times irrespective of the data cell value whether it
is "1" or "0." Note that rewriting to a page that has been once written requires execution of the
automatic block erase or automatic chip erase command before executing the automatic page
programming command again. Note that an attempt to rewrite a page two or more times without
erasing the content can cause damages to the device.
No automatic verify operation is performed internally to the device. So, be sure to read the data
programmed to confirm that it has been correctly written.
The automatic page programming operation starts when the fourth bus write cycle of the
command cycle is completed. On and after the fifth bus write cycle, data will be written
sequentially starting from the next address of the address specified in the fourth bus write cycle
(in the fourth bus write cycle, the page top address will be command written) (32 bits of data is
input at a time). Be sure to use the SW command in writing commands on and after the fourth bus
cycle. In this, any SW command shall not be placed across word boundary. On and after the fifth
bus write cycle, data is command written to the same page area. Even if it is desired to write the
page only partially, it is required to perform the automatic page programming for the entire page.
In this case, the address input for the fourth bus write cycle shall be set to the top address of the
page. Be sure to perform command write operation with the input data set to "1" for the data cells
not to be set to "0." For example, if the top address of a page is not to be written, set the input data
of the fourth bus write cycle to 0xFFFFFFFF to command write the data.
Once the fourth bus cycle is executed, it is in the automatic programming operation. This
condition can be checked by monitoring the register bit FLCS <RDY/BSY>. Any new command
sequence is not accepted while it is in automatic page programming mode. If it is desired to stop
operation, use the hardware reset function. Be careful in doing so because data cannot be written
normally if the operation is interrupted. When a single page has been command written normally
terminating the automatic page writing process, the FLCS <RDY/BSY> bit is set to "1" and it
returns to the read mode.
When multiple pages are to be written, it is necessary to execute the page programming
command for each page because the number of pages to be written by a single execution of the
automatic page program command is limited to only one page. It is not allowed for automatic
page programming to process input data across pages.
Data cannot be written to a protected block. When automatic programming is finished, it
automatically returns to the read mode. This condition can be checked by monitoring FLCS
<RDY/BSY>. If automatic programming has failed, the flash memory is locked in the mode and
will not return to the read mode. For returning to the read mode, it is necessary to use the reset
command or hardware reset to reset the flash memory or the device. In this case, while writing to
the address has failed, it is recommended not to use the device or not to use the block that
includes the failed address.
Note:
Software reset becomes ineffective in bus write cycles on and after the
fourth bus write cycle of the automatic page programming command.
TMP19A64(rev1.1)-3-11
TMP19A64F20AXBG
5)
Automatic chip erase (1MB at a time)
The automatic chip erase operation starts when the sixth bus write cycle of the command cycle is
completed.
This condition can be checked by monitoring FLCS <RDY/BSY>. While no automatic verify
operation is performed internally to the device, be sure to read the data to confirm that data has
been correctly erased. Any new command sequence is not accepted while it is in an automatic
chip erase operation. If it is desired to stop operation, use the hardware reset function. If the
operation is forced to stop, it is necessary to perform the automatic chip erase operation again
because the data erasing operation has not been normally terminated.
Also, any protected blocks cannot be erased. If all the blocks are protected, the automatic chip
erase operation will not be performed and it returns to the read mode after completing the sixth
bus read cycle of the command sequence. When an automatic chip erase operation is normally
terminated, it automatically returns to the read mode. If an automatic chip erase operation has
failed, the flash memory is locked in the mode and will not return to the read mode.
For returning to the read mode, it is necessary to use the reset command or hardware reset to reset
the flash memory or the device. In this case, the failed block cannot be detected. It is
recommended not to use the device anymore or to identify the failed block by using the block
erase function for not to use the identified block anymore.
6)
Automatic block erase (128 kB at a time)
The automatic block erase operation starts when the sixth bus write cycle of the command cycle
is completed.
This status of the automatic block erase operation can be checked by monitoring FLCS
<RDY/BSY>. While no automatic verify operation is performed internally to the device, be sure
to read the data to confirm that data has been correctly erased. Any new command sequence is not
accepted while it is in an automatic block erase operation. If it is desired to stop operation, use the
hardware reset function. In this case, it is necessary to perform the automatic block erase
operation again because the data erasing operation has not been normally terminated.
Note that any block in the protected area is not erased. It returns to the read mode upon
completing the last bus cycle of the command sequence. If an automatic block erase operation has
failed, the flash memory is locked in the mode and will not return to the read mode. In this case,
use the reset command or hardware reset to reset the flash memory or the device.
Note:

Commands can be accepted only by Chip 0. Even if automatic protection bit
programming or erasure is commanded to Chip 1, it will not result in any
setting or clearing of the protection.
Automatic programming of protection bits (for each 512 kB block)
This device is implemented with four protection bits. The protection bits can be individually set in
the automatic programming. The applicable protection bit is specified in the seventh bus write
cycle. By automatically programming the protection bits, write and/or erase functions can be
inhibited individually for each protection area. The protection status of each area can be checked
by FLCS <PROTECT3:0> to be described later. Any new command sequence is not accepted
while automatic programming is in progress to program the protection bits. If it is desired to stop
the programming operation, use the hardware reset function. In this case, it is necessary to
perform the programming operation again because the protection bits may not have been correctly
programmed. If all the protection bits have been programmed, the flash memory cannot be read
TMP19A64(rev1.1)-3-12
TMP19A64F20AXBG
from any area outside the flash memory such as the internal RAM. In this condition, the FLCS
<PROTECT3:0> register is set to "0xF" (secure state). After this, no command writing can be
performed.
Note:
Commands can be accepted only by Chip 0. Even if automatic protection bit
programming or erasure is commanded to Chip 1, it will not result in any
setting or clearing of the protection.
Note:
Software reset is ineffective in the seventh bus write cycle of the automatic
protection bit programming command. The FLCS <RDY/BSY> bit turns to "0"
after entering the seventh bus write cycle.
8)
Automatic erasing of protection bits
Different results will be obtained when the automatic protection bit erase command is executed
depending on the status of the protection bits. It depends on the status of FLCS<PROTECT3:0>
before the command execution whether it is set to "0 x F" or to any other values. Be sure to check
the value of FLCS<PROTECT3:0> before executing the automatic protection bit erase command.
• When FLCS<PROTECT3:0> is set to "0 x F" (all the protection bits are programmed):
When the automatic protection bit erase command is command written, the flash memory is
automatically initialized within the device. When the seventh bus write cycle is completed, the
entire area of the flash memory data cells is erased and then all the protection bits are erased. This
operation can be checked by monitoring FLCS <RDY/BSY>. If the automatic operation to erase
protection bits is normally terminated, FLCS<PROTECT3:0> will be set to "0x0." While no
automatic verify operation is performed internally to the device, be sure to read the data to
confirm that it has been correctly erased. For returning to the read mode while the automatic
operation after the seventh bus cycle is in progress, it is necessary to use the hardware reset to
reset the flash memory or the device. If this is done, it is necessary to check the status of
protection bits by FLCS<PROTECT3:0> after retuning to the read mode and perform either the
automatic protection bit erase, automatic chip erase, or automatic block erase operation, as
appropriate.
• When FLCS<PROTECT3:0>is other than "0 x F" (not all the protection bits are programmed):
The protection condition can be canceled by the automatic protection bit erase operation. With
this device, protection bits can be erased handling two bits at a time. The target bits are specified
in the seventh bus write cycle and when the command is completed, the device is in a condition
the two bits are erased. The protection status of each block can be checked by
FLCS<PROTECT3:0> to be described later. This status of the programming operation for
automatic protection bits can be checked by monitoring FLCS <RDY/BSY>. When the automatic
operation to erase protection bits is normally terminated, the two protection bits of
FLCS<PROTECT3:0> selected for erasure are set to "0."
In any case, any new command sequence is not accepted while it is in an automatic operation to
erase option bits. If it is desired to stop the operation, use the hardware reset function. When the
automatic operation to erase option bits is normally terminated, it returns to the read mode.

Bit 0: Ready/Busy flag bit
The RDY/BSY output is provided as a means to monitor the status of automatic operation. This bit is a
function bit for the CPU to monitor the function. When the flash memory is in automatic operation, it outputs
"0" to indicate that it is busy. When the automatic operation is terminated, it returns to the ready state and
outputs "1" to accept the next command. If the automatic operation has failed, this bit maintains the "0"
output. Returns to "1" upon power on.
(Note)
Be sure to confirm the ready status whenever a command is to be issued.
Issuing a command while the device is busy may result in a situation where further command inputs
are rejected in addition to the fact that the command cannot be transferred correctly. In such a case,
restore the system by using system reset or a reset command.
Bit 1: Programming bit
This bit notifies the flash interface that a command is to be issued to the flash memory.
Be sure to set this bit to "1" whenever a command is to be issued to the internal flash memory. Also, when all
commands have been issued, set this bit to "0" after confirming that the <RDY/BSY> bit is set to "1."
Bit 2: ROM type identification bit
This bit is read after reset to identify whether the ROM is a flash ROM or a mask ROM.
Flash ROM: "0"
Mask ROM: "1"
Bits [7:4]: Protection bits (x: can be set to any combination of areas)
Each of the protection bits (4 bits) represents the protection status of the corresponding area. When a bit is
set to "1," it indicates that the area corresponding to the bit is protected. When the area is protected, data
cannot be written into it.
TMP19A64(rev1.1)-3-14
TMP19A64F20AXBG
10) ID-Read
Using the ID-Read command, you can obtain the type and other information on the flash memory
contained in the device. The data to be loaded will be different depending on the write address to
the flash [15:14] of the fourth and subsequent bus write cycles (any input data other than 0xF0
can be used). On and after the fourth bus write cycle, when an LW command (to read an arbitrary
flash memory area) is executed after an SW command, the ID value will be loaded (execute a
SYNC command immediately after the LW command). Once the fourth bus write cycle of an IDRead command has passed, the device will not automatically return to the read mode. In this
condition, the set of the fourth bus write cycle and LW/SYNC commands can be repetitively
executed. For returning to the read mode, reset the system or use the Read or Read/reset
command.
The ID-Read command can be used when it is necessary for an application to identify whether the
device in the product has an internal flash memory or an internal ROM. This is effective because
a mask ROM doesn't have a command sequencer so it interprets any ID-Read command written
as simply a pair of SW and LW commands applied to the mask ROM. If an ID-Read command is
to be executed on a device with an internal mask ROM, it is necessary to select an address at
which the return value to a normal LW command is different from the ID-Read execution result
(ID) from a device with an internal flash memory, also taking into account any applicable security
conditions.
Note:
Setting is required when a command is to be issued to Chip 0 or Chip 1.
Refer to (4) List of Command Sequences.

TMP19A64F20AXBG
(4) List of Command Sequences
This product is implemented with two 1 MB flash ROM chips (1 MB x 2). It is necessary to identify
the target chip (0 or 1) before executing a command. This identification is made by the address bit [20].

To select the target memory access area (block), set either "0" or "1" to the address bits [20:19] in the first bus
cycle.
Always set "0" to the address bits [1:0] in the entire bus cycle. (Setting values to bits [7:2] are undefined.)
Bus cycles are "bus write cycles" except for the second bus cycle of the Read command, the fourth bus cycle of
the Read/reset command, and the fifth bus cycle of the ID-Read command. Bus write cycles are executed by SW
commands. Use "Data" in the table for the rt register [7:0] of SW commands. The address [31:16] in each bus write
cycle should be the target flash memory address [31:16] of the command sequence. Use "Addr." in the table for the
address [15:0].
In executing the bus write cycles, the interval between each bus write cycle shall be 15 system clocks or more.
The "Sync command" must be executed immediately after completing each bus write cycle.
Execute the "Sync command" immediately following the "LW command" after the fourth bus write cycle of the IDRead command.

Electrical Characteristics
The letter x in equations presented in this chapter represents the cycle period of the fsys clock
selected through the programming of the SYSCR1.SYSCK bit. The fsys clock may be derived from
either the high-speed or low-speed crystal oscillator. The programming of the clock gear function
also affects the fsys frequency. All relevant values in this chapter are calculated with the high-speed
(fc) system clock (SYSCR1.SYSCK = 0) and a clock gear factor of 1/fc (SYSCR1.GEAR[2:0] =
000).

Note 1:
SCL clock low width (output) is calculated with: (2n-1 +58)/(fsys/2)
Note 2:
SCL clock high width (output) is calculated with (2n-1 +12)/(fsys/2)
Notice: On I2C-bus specification, Maximum Speed of Standard mode is 100KHz ,Fast mode is
400Khz. Internal SCL clock Frequency setting should be shown above Note1 & Note2.
Note 3:
The output data hold time is equal to 12x
Note 4: The Philips I2C-bus specification states that a device must internally provide a hold time of at
least 300 ns for the SDA signal to bridge the undefined region of the fall edge of SCL.
However, the 19A64 SBI does not satisfy this requirement. Also, the output buffer for SCL
does not incorporate slope control of the falling edges; therefore, the equipment manufacturer
should design so that the input data hold time shown in the table is satisfied, including tr/tf of
the SCL and SDA lines.

Note 1: If the current bus cycle has not terminated due to wait-state insertion, the
TMP19A64F20BXBG does not respond to BUSRQ until the wait state ends.
Note 2: This broken line indicates that output buffers are disabled, not that the
signals are at indeterminate states. The pin holds the last logic value present
at that pin before the bus is relinquished. This is dynamically accomplished
through external load capacitances. The equipment manufacturer may
maintain the bus at a predefined state by means of off-chip restores, but he
or she should design, considering the time (determined by the CR constant)
it takes for a signal to reach a desired state. The on-chip, integrated
programmable pullup/pulldown resistors remain active, depending on
internal signal states.
