Programming the M8 USB Microcontrollers with a Hi-Lo
Programmer
Introduction
The purpose of this application note is to show developers
how to program the M8 USB microcontrollers using the Hi-Lo
programmer. Several vendors have programmers that
support the M8 USB microcontrollers. Developers using a
different programmer should contact the programming
manufacturers for support. This application note only focuses
on the inexpensive CY3649 Hi-Lo System—Cypress USB
Programmer For Starter. Cypress parts can be purchased
from the Cypress local sales office or from the Cypress Online
Store at: http://www.cypress.com/support/how_to_buy.cfm.
Materials Needed
The new CY3649 looks similar to the old programmer that
was included with the discontinued development kit, the
CY3640. The difference is that the CY3649 has been
designed to support all the M8 USB microcontrollers and is
labeled Cypress USB Programmer For Starter while the old
programmer only supports the CY7C63000 and is labeled
Programmer for CY7C63000.
The programmer’s hardware is where the programming
process takes place. Communication between the
programmer and Cystart.exe on the PC is through the RS232
cable.
The Adapter Base adapts the programmer for a specific
package type. Three types of adapters are available: SSOP,
SOIC, and PDIP. Depending on the package type of the chip,
a corresponding adapter is needed. Refer to Appendix A for
the required Adapter Base.
The Matrix Card routes the signal from the programmer to the
correct pin outs on the chip. Different parts have different pin
out listings. Refer to Appendix A for the required Matrix Card.
Figure 1 below shows the adapter inserted into the
programmer's socket, and the matrix card inserted into the
adapter. Figure 2 shows the Cystart.exe GUI running on the
PC.
The following tools are needed:
• The programmer, Hi-Lo System—Cypress USB
Programmer For Starter (Cypress Part ID: CY3649).
• A center negative, 9VDC, 1000mA output wall bug
(provided with the CY3649).
• A RS232 cable with a female connector-type at one end
and male connector-type at the other (provided with the
CY3649).
• The Cypress Starter Kit USB Programmer software
(Cystart.exe). This is freeware and can be downloaded
from the Cypress web site: http://www.cypress.com/.

• An Adapter Base (Purchased separately. See Appendix A
for the required Adapter Base).
• A Matrix Card (Purchased separately. See Appendix A for
the required Matrix Card).
1. Power the programmer with the provided wall bug.
Operational Overview
2. Connect the RS232 cable from the programmer to the PC.
Cystart (GUI) is the software that runs on the PC. Cystart
allows the user to interface with the programmer such as
choosing the file to be programmed, setting target chip being
used, choosing the COM port for the serial cable and its baud
rate, reading the existing program on the chip’s PROM,
checking whether the chip’s PROM is blank, etc.

Step-By-Step Procedures
•
3. Insert the Matrix Card into the Adapter Base with the
printed side facing up. Note that the Matrix Card is
two-sided. Each side supports a different part. The labels
printed on the card show which side belongs to which part.
4. Put the Adapter Base into the zero-insertion-force (ZIP)
socket on the programmer and push the lever on the
programmer down to lock the Adapter Base in its position.
Pin 1 of the Adapter Base should be at the top left position
on the socket as shown in Figure 1.

10.A File Format window will open. Select the File Format =
“Intel HEX,” Unused Bytes = “Don’t Care” or “FF,” then click
OK. The File Format window will automatically close.
5. Place a chip to be programmed into the Adapter Base’s
ZIP socket and push the Adapter Base’s lever forward to
secure the chip in its position. Note that the chip should be
top justified, i.e., pin 1 of the chip should be placed at the
top left position on the Adapter Base’s socket.
11.Click the Program button to start programming.
Note that after the programming is done, the user needs to
click on the “Cancel” button to close the Program window.
6. Open the Cystart.exe software on the PC. See Figure 2.
7. From Cystart, click on the Setup menu. The I/O Base
Address window will pop up allowing the user to select the
COM Port and the desired baud rate. The “Programmer
Status” message at the end of this window shows status
of the serial communication between the Cystart and the
programmer hardware. When the “Programmer Status”
message changes to “EXIST,” click the “Cancel” button to
close this window.
Other features of the programmer are:
The Blank Check enables the user to verify that the chip
PROM cells contain all 1s.
With the chip inserted in the Adapter Base’s socket, clicking
the Read button and then the Edit menu allows the user to
read the contents of the PROM in the chip. The Edit menu
also enables the user to search or move bytes in the buffer,
fill the buffer with certain values, or edit the buffer. Note that
the PROM cells are defaulted to all 1s. Even though the M8
chips are One Time Programmable (OTP), reprogramming
the chips with the cells being changed from “1” to “0” is
permissible (assuming the security fuse has not been blown),
but the reverse is not possible.
At this point, communication between the programmer and
the Cystart GUI has been established. From the Cystart GUI,
the continuing steps allow the user to select the part and the
.hex file to be programmed on the part. The .hex file is
generated by the Cyasm assembler. To learn how to create
the .hex file, refer to the Cyasm User’s Guide, which can be
downloaded
from
the
Cypress
web
site
at:
http://www.cypress.com/.
The Verify button ensures that the chip's PROM matches the
contents of the buffer.
8. Click on the Device menu and select the device to be
programmed.
After the chip has been programmed, clicking the
Security/Run buttons blows the chip’s security fuse to prevent
the program on the chip to be read. Reading the chip after the
security fuse has been blown returns 0xFFs.
9. From the File menu, select Load File to Buffer. The Load
File menu will open to allow the user to browse to the .hex
file that need to be programmed on the chip. Click on the
.hex file and then OK. Note that the Cystart software is
16-bit, so files and folders with long names will be
truncated.

Troubleshooting
• The chip is not locked on Adapter Base. Pushing the
Adapter Base's lever forward locks the chip on the ZIP
socket. See Figure 1.
“Error Identification on hardware!” message
• You may see this message the first time you open Cystart.
This means the COM port setting on Cystart does not
match the port where the RS232 cable is connected. Click
“OK” on the error message. Go to the Setup menu and
select the correct COM port. The Programmer Status
message should change to EXIST.
• The Adapter Base bottom pins have loose contact with the
programmer socket. Make sure the Adapter Base bottom
pins have good contact with the programmer, and the
Adapter Base sits firmly on the programmer (the
programmer’s lever is pushed down to lock the Adapter
Base in its position).
• The programmer is not powered. Also make sure that the
power supplied to the programmer is 9 VDC 1000-mA
center negative.
• The incorrect side of the matrix card is inserted into the
Adapter Base, or the matrix card has loose contacts with
the Adapter Base.
• The COM port has been assigned to another application
by the host PC. This problem occurs when the user unplugs
the RS232 cable from another running application without
terminating it. Therefore, when Cystart tries to set up the
serial communication with the programmer, the host PC
responds with a message saying the COM port selected is
not available even though the RS232 cable is physically
connected to the programmer.
• The security fuse has been blown.
• The chip is corrupted or not blank. Occasionally, the Blank
Check feature fails. The alternative way to check the
PROM is to do Read/Edit. If the part is blank, all bytes
should be 0xFFs.
The part has been programmed successfully, but does
not work
• No .hex file was loaded onto the buffer. This results in the
chip being programmed with 0x00.
“Error at 000000!” message.
• The chip is incorrectly positioned on the Adapter Base’s
socket. The chip should be top justified on the socket, i.e.,
pin 1 of the chip should be placed at the top, left position
on the socket. See Figure 1.
• The part being programmed does not match the device
selected in the Device menu.
• An incorrect .hex file has been programmed on the chip.
To verify, use the Read feature to compare the checksums
of the program on the PROM and the file on the buffer.
