bq2022AEVM (HPA125 Rev. B) EV2300
SDQ HDQ
VSS GND
PROG VOUT
To program the EPROM of bq2022AEVM, a 12-V pulse must be generated on the SDQ line. The HPA125
board has an additional circuit included that permits generating this pulse when using a power supply set
to 12 V and the VOUT output of the EV2300. The evaluation software controls this pulse for EPROM
programming.
When programming the EPROM, it is expected that a 12-V supply must be connected to the HPA125
board at the 12-V input terminal of the HPA125 board. Ensure that the ground of the power supply is
connected to VSS of the board.
A jumper (J3) must be connected when using the EPROM programming circuit.
7.2.1 Normal Operation
Normal operation includes performing any of the ROM commands, reading the 1 K-bit EPROM and
reading the EPROM Status Memory.
7.2.2 EPROM Programming
To program EPROM registers, a 12-V pulse must be sent across the SDQ line after sending the code
0x5A during a write command. See the bq2022A data sheet (SLUS724) for a specific description of
EPROM programming requirements. When programming EPROM registers, the following must be
ensured:
• J3 jumper is connected.
• VOUT output of EV2300 is connected to PROG input of HPA125 board.
• Power supply set to 12 V is connected across the 12 V and VSS inputs of HPA125 board.

program the STATUS bytes. It requires that the hardware is set up as described in the EPROM
programming of this user’s guide.
8.3.1 1 K-Bit EPROM
The EPROM memory map is organized in four pages of 32 bytes each. All registers can be read by
clicking on the Read Memory button. As the registers of a specific page are being read, the page number
is highlighted in red.
The two methods of programming the EPROM using the EVSW follow.
1. Click on a specific grid that corresponds to the register that needs to be written. Write the hexadecimal
value of the data that needs to be written, and then press ENTER.
2. The other method of programming the EPROM is by importing a data file that contains all the values to
be programmed. The data file has the file extension .epr. An example of a data file is included with the
EVSW. To create additional data files, modify the example file so that the values on the right side of
the file represent the desired values. Save the file with a different name ensuring that the extension
.epr is used. To import a file into the grid, go to File|Open Data File, and select the appropriate file.
Once the file is opened, the grid is filled in with the values contained in the data file. Click on the Write
