Quick Links

The bq2022A is a 1 K-bit serial EPROM containing a factory-programmed, unique 48-bit identification
number, 8-bit CRC generation, and an 8-bit family code. A 64-bit status register controls write protection
and page redirection.
The purpose of the evaluation software is to demonstrate the functionality of the bq2022A. The bq2022A
evaluation board can be used for one or two ICs.
The bq2022A is ideal for applications such as battery pack configuration parameters, record maintenance,
asset tracking, product revision status, and access-code security.

    IC. The circuit module includes a 3-pin SOT23 dual socket, a bq2022A IC, a Zener diode for host protection during EPROM programming, and a programming circuit that generates a 12-V pulse when used with a power supply and a control signal. In a typical application, only the bq2022A IC and a pullup resistor is required.

  • Page 8: Performance Specification Summary

    This section describes how to install the bq2022AEVM PC software, and how to connect the different components of the EVM. Use the following steps to install the bq2022A evaluation software: 1. Insert the CD ROM into a CD ROM drive.
  • Page 9: Wire Connection

    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: •...
  • Page 10 Sections Within the ROM CMD Page Application — This section determines the number of bq2022A devices that are on the SDQ bus. If only one device is used, then select Single Device. This option sends the SKIP ROM command before any communication attempt is made with the device.
  • Page 11 Once the file is opened, the grid is filled in with the values contained in the data file. Click on the Write Memory button so that the values are programmed into the EPROM.

  • Page 12 8.3.2 Status Bytes This section allows the user to read or write the EPROM Status bytes of the bq2022A. The registers are programmed by clicking on the appropriate grid, entering the desired value, and pressing ENTER. Buttons are provided for the user to select specific pages for write protection. By selecting any of the Write Protection Bits button, register 0x00 of status registers is written automatically so that the corresponding bit is cleared.
