Product Overview

The BQ2022AEVM-001 evaluation module purpose is to demonstrate the functionality of the bq2022A, which is a 1Kbit serial EPROM containing a factory programmed, unique 48bit identification number, 8bit CRC generation, and the 8bit family code(09h). A 64bit status register controls write protection and page redirection. The bq2022A based circuit module is ideal for programming the 1Kbit EPROM and the STATUS bytes of the bq2022A 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 12V pulse when used with a power supply and a control signal. In a typical application, only the bq2022A IC and a pull-up resistor is required. 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.
  • 1024bits of One Time Programmable (OTP) EPROM For Storage Of user programmable configuration data
  • Factory programmed unique 64Bit identification number
  • Bus interface architecture allowing multiple bq2022As attached to a single host
  • Single wire interface to reduce circuit board routing
  • Synchronous communication reduces host interrupt overhead
  • 15KV IEC 61000-4-2 ESD compliance on data pin
  • No standby power required


Security, Maintenance & Repair, Power Management


BQ2022A & HPA125 revision B board, PC interface board EV2300, CD ROM, USB Cable (Type A-B)


These devices have limited built in ESD protection. The leads should be shorted together or device placed in conductive foam during storage or handling to prevent electrostatic damage to MOS gates.
