How do you replace TMPN3120B1AM or TMPN3120E1M with TMPN3120A20M?
How do you replace TMPN3120A20M with TMPN3120FE3M?
How do you replace TMPN3120FE3M with TMPN3120FE5M?
TMPN3120A20M is pin-to-pin compatible with TMPN3120B1AM and TMPN3120E1M. However, TMPN3120A20M has a different firmware version as it has additional features such as increased ROM. So, the application program needs to be re-compiled/linked to use the TMPN3120A20M. Also, TMPN3120A20M, TMPN3120FE3M and TMPN3120FE5M are pin-to-pin compatible parts, with varying size of EEPROM and RAM. As your application grows, you can replace the existing part with the one with increased EEPROM and RAM. However, doing this also requires you to re-build the application image as described below. To rebuild (re-compile and link) the application program, do the following:
Step 1: Make sure you have the most current software for the LonBuilder or NodeBuilder development tools. For information on development tools software update, please refer to the Software Updates section. Note: Link Software updates above in the web-page to: http://www.toshiba.com/taec/components/Generic/software_updates.shtml
Step 2: Using the LonBuilder development tool, follow the procedure for building an application image. Refer to the LonBuilder's User Guide for detailed instructions on this procedure. Some of the key steps are described below. Select App Node option from the LonBuilder's Home menu.
1) From App Node menu options, select HW Properties, and specify the following parameters:
HW Property Name:
Neuron Chip:
3120 option for 3120B1AM and 3120E1M
3120A20 option for 3120A20M and 3120A20U
3120E3 option for 3120FE3M and 3120FE3U
3120E5 option for 3120FE5M
Input Clock Rate:
For 20MHz clock rate, see the note below.
Neuron Chip Firmware:
Firmware version: 0
Note: Current version of LonBuilder software does not support selecting 20MHz input clock rate from the menu. If you are using 20MHz clock, you can select any clock rate in the option above (temporarily), and change it later using the NEI20MHz.exe utility (as described in the step # below).
2) From App Node menu options, select HW Properties, and specify the following parameters:
App HW Name:
HW Type: Custom Node
HW Prop. Name:
Specify other parameters to be the same used in the previous application image for the Neuron Chip that you are replacing. For detailed information on selecting other steps, refer to the LonBuilder's User Guide, available from Echelon.
3) From App Node menu options, select App Images, and specify the parameters to be the same used in the previous application image for the Neuron Chip that you are replacing.
4) From App Node menu options, select Node Specs, and specify the following parameters:
Node Name:
App Image Name:
Target HW Name:
Specify other parameters to be the same used in the previous application image for the Neuron Chip that you are replacing.
5) Perform the build by selecting Automatic Build from LonBuilder's menu.
Note: In some cases, the size of application image generated may increase slightly even if you didn't make any changes to the application code. This may be because of a newer compiler version being used by LonBuilder. If you are replacing E1M with A20M, since both of these have the same size of EEPROM, in a rare scenario, the new application image generated may not fit into the EEPROM. In such a case, you can address this by using compiler instructions (#pragma codegen ***).
6) Select Node, and perform Export to create a .NEI file. Make sure to select "Intel Hex format" as the Toshiba Neuron Programmer only supports the Intel Hex Format.

Why is a service LED necessary?
The service pin of a Neuron Chip shows the Configuration State of a chip. As shown in the following figure, if LED is connected with resistance, the Configuration State of the present chip can be checked in the state of LED.
The following three states are shown according to the state of LED.
LED is OFF: Config State
The chip (node) is operating normally. All the nodes under operation should be in this state
The node of this state has a communication parameter, an application program, and address information.
LED is Blinking (1/2Hz): Unconfig State
The node of this state has a communication parameter, an application program.
By setting address information as the node of this state, it shifts to a Config state and starts operating. ?LED is dimly lit (76kHz): Application less State
All Neuron 3120 at shipping time is in this state. The node of this state has only the communication parameter.\
Service LED is the method of knowing the Configuration State of a node easily. It is highly useful at the time of installation/debugging in the field. Even if there is no service LED, there is no problem functionally. However, in order to make correspondence at a trouble smooth, we recommend you to also prepare service LED with a service pin switch (Please refer to Q**: of this FAQ).

写的不是非常清楚吗？？？
翻译过来就行了！！！
第一步：确定你的开发工具支持你的芯片固件
不支持的需要更新软件。
第二步：使用开发工具
1) 选择硬件特性
3120 对应 3120B1AM and 3120E1M
3120A20 对应 3120A20M and 3120A20U
3120E3 对应 3120FE3M and 3120FE3U
3120E5 对应 3120FE5M
时钟速率: 5 10 20
其它的都是正常步骤！！
