1 CMT2380F16 Writer Introduction
1.1 Hardware Introduction
The CMT2380F16 Writer is a programmer designed for the CMT2380F16 chip applying USB interface for programming. It can be
programmed online using USB bus power, or programmed offline using an external power supply. Moreover , multiple units can
be connected together for one-click batch programming (or for batch programming in factory). The Writer hardware structure is
both simple and compact. The user-friendly software UI interface makes this programmer very easy to use.
The Writer's PCBAappearance is shown in the below figure.

3 Serial Number Usage
The serial number consists of 12 characters (ASCII code) plus a 4-byte number and is stored between the starting address and
the end address. For different chips, the string is the same; if the auto increment number flag is checked, the number will be
automatically incremented by 1 for each chip programmed.
Figure 20. Series Number Usage
The operation flow is as follows.
enable the serial number function. The serial number has a total of 16 bytes (a 12-byte string and a 4-byte number).
the is string, up to 12 bytes of characters ,is used for factory or product name
the number, up to 4 bytes with a valid value range as 0x00000000~0xFFFFFFFF.

4 Special Consideration
IAP Space
Figure 23. IAP Space

AN211
Rev 0.5 | 18/24
www.cmostek.com
This value determines the the IAP space size. Users can also change the IAP space size by changing the register IAPLB in the
program (IAP start address = IAPLB*256, IAPLB must be even).
2. The Chip provides 16 K Flash。The space near to 0x0000 address is for user AP program, near to 0x3FFF (ie 16K) address is
for ISP code and the space between the 2 spaces is for IAP (including IAP (data), serial number and IAP space). Pleas make
sure the 3 spaces setting are not overlapped (Note that the minimum unit of Flash area division is a sector, which is 512 bytes).
3. If the contents of IAP (Data) and Serial Number are not changed after programming, it is highly recommended not put them
into the same sector with IAP Space. Otherwise, when IAP is erased in the program, IAP (data) and serial number will also be
erased. Suggest put them between tje AP (program) space and IAP space space.
Firmware upgrading
When the following message shows up that means the U1 writer needs to be updated firmware. Please make sure the USB cable
should NOT unplug during the updating process. Otherwise, The U1 writer will cause unrecoverable damaged.

5 Appendix
5.1 Chip Storage Space Configuration
The storage space of the CMT2380F16 is divided into the 3 categories.
AP space: used to store client applications and data. This part of the data can be erased, read and written by the
programmer and ISP program.
IAP space: It is a non-volatile data storage space that can be used as an EEPROM. This part of the data can be erased,
read and written by the programmer, ISP program andAP application.
ISP space: It is a special storage space, where program code can run independently. It is generally used for online
programming of AP and IAP space, and the storage space of ISP itself can only be programmed by the programmer.
CMT2380F16 provides a total of 8 Kbytes (0000h ~ 1FFFh) storage space as shown in the below figure.
Figure 25. CMT2380F16 Storage Space
The ISP space is configured by the user through the programmer with ISP space ranging from 0 kbytes to 3.5
kbytes. As the IAP space and AP space of the CMT2380F16 are shared, apart from the ISP space, the rest of
8K space is the AP and IAP space.
