TMP86F808
Pin Function
The TMP86F808 has MCU mode and serial PROM mode.
(1) MCU mode
In the MCU mode, the TMP86F808 is a pin compatible with the TMP86C408/808 (Make sure
to fix the TEST pin to low level).
(2) Serial PROM mode
The serial PROM mode is set by fixing TEST pin, P10 and P11 at “high” respectively when
RESET pin is fixed “low”.
After release of reset, the built-in BOOT ROM program is activated and the built-in flash
memory is rewritten by serial I/F (UART).

2. Serial PROM Mode
2.1
Outline
The TMP86F808 has a 2-Kbyte BOOT ROM for programming to flash memory. This BOOT ROM
is a mask ROM that contains a program to write the flash memory on-board. The BOOT ROM is
available in a serial PROM mode and it is controlled by TEST pin and RESET pin and 2 I/O pins,
and is communicated with UART. There are four operation modes in a serial PROM mode: flash
memory writing mode, RAM loader mode, flash memory SUM output mode and product
discrimination code output mode. Operating area of serial PROM mode differs from that of MCU
mode. The operating area of serial PROM mode shows in Table 2.1.1.

Operation Mode
There are four operating modes in serial PROM mode: Flash memory writing mode, RAM loader
mode, flash memory SUM output mode and product discrimination code output mode. For details
about these modes, refer to (1) Flash memory writing mode through (4) Product discrimination code
output mode.
(1) Flash memory writing mode
The data are written to the specified flash memory addresses. The controller should send the
write data in the Intel Hex format (Binary). For details of writing data format, refer to 2.7
“Flash Memory Writing Data Format”.
If no errors are encountered till the end record, the SUM of 8 Kbytes of flash memory is
calculated and the result is returned to the controller.
To execute the flash memory writing mode, the TMP86F808 checks the passwords except a
blank product. If the passwords did not match, the program is not executed.
(2) RAM loader mode
The RAM loader transfers the data into the internal RAM that has been sent from the
controller in Intel Hex format. When the transfer has terminated normally, the RAM loader
calculates the SUM and sends the result to the controller before it starts executing the user
program. After sending of SUM, the program jumps to the start address of RAM in which the
first transferred data has been written. This RAM loader function provides the user's own way
to control on-board programming.
To execute the RAM loader mode, the TMP86F808 checks the passwords except a blank
product. If the passwords did not match, the program is not executed.
(3) Flash memory SUM output mode
The SUM of 8 Kbytes of flash memory is calculated and the result is returned to the
controller.
The BOOT ROM does not support the reading function of the flash memory. Instead, it has
this SUM command to use. By reading the SUM, it is possible to manage Revisions of
application programs.
(4) Product discrimination code output mode
The product discrimination code is output as a 13-byte data, that includes the start address
and the end address of ROM. (In case of TMP86F808, the start address is E000H and the end
address is FFFFH.) Therefore, the controller can recognize the device information by using this
function.

Note 3: Refer to 2.9 “Checksum (SUM)”.
Note 4: Refer to 2.11 “Passwords”.
Note 5: If all data of vector area are “00H” or “FFH”, the passwords comparison is not executed
because the device is considered as blank product. However, it is necessary to specify the
password count storage addresses and the password comparison start address even though
it is a blank product. If a password error occurs, the UART function of TMP86F808 stops
without returning error code to the controller. Therefore, when a password error occurs, the
TMP86F808 should be reset by RESET pin input.
Note 6: The time between data records needs over 1 ms.
86F808-13
2007-08-07
TMP86F808
Description of flash memory writing mode
1.
The receive data in the 1st byte is the matching data. When the boot program starts in serial
PROM mode, TMP86F808 (Mentioned as “device” hereafter) waits for the matching data
(5AH) to receive. Upon receiving the matching data, it automatically adjusts the UART’s
initial baud rate to 9,600bps.
2.
When the device has received the matching data, the device transmits the data “5AH” as an
echo back to the controller. If the device can not receive the matching data, the device does not
transmit the echo back data and waits for the matching data again with changing baud rate.
Therefore, the controller should send the matching data continuously until the device
transmits the echo back data.
3.
The receive data in the 3rd byte is the baud rate modification data. The six kinds of baud rate
modification data shown in Table 2.4.1 are available. Even if baud rate changing is no need,
be sure to send the initial baud rate data (28H: 9,600 bps). The changing of baud rate is
executed after transmitting the echo back data.
4.
When the 3rd byte data is one of the baud rate modification data corresponding to the device's
operating frequency, the device sends the echo back data which is the same as received baud
rate modification data. Then the baud rate is changed. If the 3rd byte data does not
correspond to the baud rate modification data, the device stops UART function after sending
3 bytes of baud rate modification error code: (62H).
5.
The receive data in the 5th byte is the command data (30H) to write the flash memory.
6.
When the 5th byte is one of the operation command data shown in Table 2.5.1, the device
sends the echo back data which is the same as received operation command data (in this case,
30H). If the 5th byte data does not correspond to the operation command data, the device
stops UART function after sending 3 bytes of operation command error code: (63H).
7.
The 7th byte is used as an upper bit (Bit15 to bit8) of the password count storage address.
When the receiving is executed correctly (No error), the device does not send any data. If the
receiving error or password error occur, the device does not send any data and stops UART
function.
8.
The 9th byte is used as a lower bit (Bit7 to bit0) of the password count storage address. When
the receiving is executed correctly (No error), the device does not send any data. If the
receiving error or password error occur, the device does not send any data and stops UART
function.
9.
The 11th byte is used as an upper bit (Bit15 to bit8) of the password comparison start
address. When the receiving is executed correctly (No error), the device does not send any
data. If the receiving error or password error occur, the device does not send any data and
stops UART function.
10. The 13th byte is used as a lower bit (Bit7 to bit0) of the password comparison start address.
When the receiving is executed correctly (No error), the device does not send any data. If the
receiving error or password error occur, the device does not send any data and stops UART
function.
11. The 15th through the m’th bytes are the password data. The number of passwords is the data
(N) indicated by the password count storage address. The password data are compared for N
entries beginning with the password comparison start address. The controller should send N
bytes of password data to the device. If the passwords do not match, the device stops UART
function without returning error code to the controller. If the data of vector addresses (FFE0H
to FFFFH) are all “FFH”, the comparison of passwords is not executed because the device is
considered as a blank product.
86F808-14
2007-08-07
TMP86F808
12. The receive data in the m’th + 1 through n’th − 2 byte are received as binary data in Intel Hex
format. No received data are echoed back to the controller. The data which is not the start
mark (3AH for “:”) in Intel Hex format is ignored and does not send an error code to the
controller until the device receives the start mark. After receiving the start mark, the device
receives the data record, that consists of length of data, address, record type, writing data and
checksum. After receiving the checksum of data record, the device waits the start mark data
(3AH) again. The data of data record is temporarily stored to RAM and then, is written to
specified flash memory by page (32 bytes) writing. For details of an organization of flash
memory, refer to 2. “Serial PROM Mode”. Since after receiving an end record, the device starts
to calculate the SUM, the controller should wait the SUM after sending the end record. If
receive error or Intel Hex format error occurs, the device stops UART function without
returning error code to the controller.
13. The n’th − 1 and the n’th bytes are the SUM value that is sent to the controller in order of the
upper byte and the lower byte. For details on how to calculate the SUM, refer to 2.9
“Checksum (SUM)”. The SUM calculation is performed after detecting the end record, but the
calculation is not executed when receive error or Intel Hex format error has occurred. The
time required to calculate the SUM of the 8 Kbytes of Flash memory area is approximately
100 ms at fc = 16 MHz. After the SUM calculation, the device sends the SUM data to the
controller. After sending the end record, the controller can judge that the transmission has
been terminated correctly by receiving the checksum.
14. After sending the SUM, the device waits for the next operation command data.

Note 5: If all data of vector area are “00H” or “FFH”, the passwords comparison is not executed
because the device is considered as blank product. However, it is necessary to specify the
password count storage addresses and the password comparison start address even though
it is a blank product. If a password error occurs, the UART function of TMP86F808 stops
without returning error code to the controller. Therefore, when a password error occurs, the
TMP86F808 should be reset by RESET pin input.
Note 6: Do not send only end record after transferring of password string. If the TMP86F808 receives
the end record only after reception of password string, it does not operate correctly.
Description of RAM loader mode
1.
The process of the 1st byte through the 4th byte are the same as flash memory writing mode.
2.
The receive data in the 5th byte is the RAM loader command data (60H) to write the user’s
program to RAM.
3.
When the 5th byte is one of the operation command data shown in Table 2.5.1, the device
sends the echo back data which is the same as received operation command data (in this case,
60H). If the 5th byte data does not correspond to the operation command data, the device
stops UART function after sending 3 bytes of operation command error code: (63H).
4.
The process of the 7th byte through the m’th byte are the same as flash memory writing
mode.
5.
The receive data in the m’th + 1 through n’th − 2byte are received as binary data in Intel Hex
format. No received data are echoed back to the controller.
The data which is not the start mark (3AH for “:”) in Intel Hex format is ignored and does not
send an error code to the controller until the device receives the start mark. After receiving
the start mark, the device receives the data record, that consists of length of data, address,
record type, writing data and checksum. After receiving the checksum of data record, the
device waits the start mark data (3AH) again. The data of data record is written to specified
RAM by the receiving data. Since after receiving an end record, the device starts to calculate
the SUM, the controller should wait the SUM after sending the end record. If receive error or
Intel Hex format error occurs, the UART function of TMP86F808 stops without returning
error code to the controller.
6.
The n’th − 1 and the n’th bytes are the SUM value that is sent to the controller in order of the
upper byte and the lower byte. For details on how to calculate the SUM, refer to 2.9
“Checksum (SUM)”. The SUM calculation is performed after detecting the end record, but the
calculation is not executed when receive error or Intel Hex format error has occurred.
The SUM is calculated by the data written to RAM, but the length of data, address, record
type and checksum in Intel Hex format are not included in SUM.
7.
The boot program jumps to the first address that is received as data in Intel Hex format after
sending the SUM to the controller.

TMP86F808
2.7
Flash Memory Writing Data Format
Flash memory area of TMP86F808 consists of 255 pages and one page size is 32 bytes.
Writing to flash memory is executed by page writing. Therefore, it is necessary to send 32 bytes
data (for one page) even though only a few bytes data are written. Figure 2.7.1 shows an
organization of flash memory area. When the controller sends the writing data to the device, be
sure to keep the format described below.
1.
The address of data after receiving the flash memory writing command should be the first
address of page. For example, in case of page 2, the first address should be E040H.
2.
If the last data’s address of data record is not end address of page, the address of the next data
record should be the address + 1 and the last data’s address must point to the last address of
this page. For example, if the last data’s address is E00FH (Page0), the address of the next data
record should be E010H (Page0) and the address of the last data should be E01FH (Page0).
3.
The last data’s address of data record immediately before sending the end record should be the
last address of page. For example, in case of page 1, the last data’s address of data record should
be E03FH.
Note: Do not write only the vector area (FFF0H to FFFFH) when all data of flash memory are the
same data. If the vector area is only written, the next operation can not be executed because of
password error.

Meaning of Transmit Data
Baud rate modification error occurred.
Operating command error occurred.
Framing error in received data occurred.
Overrun error in received data occurred.
Checksum (SUM)
(1) Calculation method
SUM consists of byte + byte.... + byte, the checksum of which is returned in word as the
result.
Namely, data is read out in byte and checksum of which is calculated, with the result
returned in word.
Example:
A1H
B2H
C3H
D4H
If the data to be calculated consists of the four bytes shown to the
left, SUM of the data is
A1H + B2H + C3H + D4H = 02EAH
= 02H
SUM (HIGH)
SUM (LOW)
= EAH
The SUM returned when executing the flash memory write command, RAM
loader command, or flash memory SUM command is calculated in the manner
shown above.
(2) Calculation data
The data from which SUM is calculated are listed in Table 2.9.1 below.

2.10 Intel Hex Format (Binary)
1.
After receiving the SUM of a record, the device waits for the start mark data (3AH for “:”) of the
next record. Therefore, the device ignores the data, which does not match the start mark data
after receiving the SUM of a record.
2.
Make sure that once the controller program has finished sending the SUM of the end record, it
does not send anything and waits for two bytes of data to be received (Upper and lower bytes of
SUM). This is because after receiving the SUM of the end record, the boot program calculates
the SUM and returns the calculated SUM in two bytes to the controller.
3.
If a receive error or Intel Hex format error occurs, the UART function of TMP86F808 stops
without returning error code to the controller. In the following cases, an Intel Hex format error
occurs:
•
When the record type is not 00H, 01H, or 02H
•
When a SUM error occurred
•
When the data length of an extended record (Type = 02H) is not 02H
•
When the address of an extended record (Type = 02H) is larger than 1000H and after that,
receives the data record
•
When the data length of the end record (Type = 01H) is not 00H
2.11 Passwords
The area in which passwords can be specified is located at addresses E000H to FF9FH. The
vector area (from FFA0H to FFFFH) can not be specified as passwords area. The device compares
the stored passwords with the passwords, which are received from the controller. If all data of
vector area are “00H” or “FFH”, the passwords comparison is not executed because the device is
considered as blank product. It is necessary to specify the password count storage addresses and
the password comparison start address even though it is a blank product.

Note 1: When all data of addresses from FFE0H to FFFFH area are “00H” or “FFH”, the device is
judged as blank product.
Note 2: The same three or more bytes consecutive data can not be used as password.
When the password includes the same consecutive data (three or more bytes), the password
error occurs. If the password error occured, the UART function of device stops without
returning error code.
Note 3: *: Don’t care.
Note 4: When the password doesn’t match the above condition, the password error occurs. If the
password error occured, the UART function of device stops without returning error code.
Note 5: In case of the blank product, the device receives Intel Hex Format immediately after receiving
PCSA without receiving password strings. In this time, because the device ignores the data

except the start mark data (3AH for “:”) as Intel Hex Format data, even if external controller
transmitted dummy password strings, process operates correctly. However, if the dummy
password strings contain data “3AH”, the device detects it as start mark data mistakenly, and
device stops process without returning error doce. Therefore, if these process becomes
issue, the external controller should not transmit the dummy password strings.

Password string
A password string sent from the controller is compared with the specified data in the flash
memory. If the password string does not match the specified data in the flash memory, a
password error occurs and the TMP86F808 stops operating.
4.
Handling of password error
If a password error occurs, the UART function of TMP86F808 stops without returning error
code to the controller. Therefore, when a password error occurs, the TMP86F808 should be reset
by RESET pin input.

Note: The recommended operating conditions for a device are operating conditions under which it
can be guaranteed that the device will operate as specified. If the device is used under
operating conditions other than the recommended operating conditions (Supply voltage,
operating temperature range, specified AC/DC values etc.), malfunction may occur. Thus,
when designing products which include this device, ensure that the recommended operating
conditions for the device are always adhered to.

Note 1: The total error includes all errors except a quantization error, and is defined as a maximum
deviation from the ideal conversion line.
Note 2: Conversion time is different in recommended value by power supply voltage.
About conversion time, please refer to “10-Bit AD Converter”.
Note 3: Please use input voltage to AIN input pin in limit of VDD − VSS.
When voltage of range outside is input, conversion value becomes unsettled and gives affect
to other channel conversion value.
Note 4: The relevant pin for IREF is VDD, so that the current flowing into VDD is the power supply
current IDD + IREF.

Note 1: To ensure stable oscillation, the resonator position, load capacitance, etc. must be
appropriate. Because these factors are greatly affected by board patterns, please be sure to
evaluate operation on the board on which the device will actually be mounted.
Note 2: For the resonators to be used with Toshiba microcontrollers, we recommend ceramic
resonators manufactured by Murata Manufacturing Co., Ltd.

Handling Precaution
•
The solderability test conditions for lead-free products (indicated by the suffix G in product
name) are shown below.
1. When using the Sn-63Pb solder bath
Solder bath temperature = 230 °C
Dipping time = 5 seconds
Number of times = once
R-type flux used
2. When using the Sn-3.0Ag-0.5Cu solder bath
Solder bath temperature = 245 °C
Dipping time = 5 seconds
Number of times = once
R-type flux used
The pass criteron of the above test is as follows:
Solderability rate until forming ≥ 95 %
•
When using the device (oscillator) in places exposed to high electric fields such as cathoderay tubes, we recommend electrically shielding the package in order to maintain normal
operating condition.
