The OB1022 is 1024x8 bits serial MTP(Multi Time Programmable) storage with DATA interface in 3-Pin SOT23 package.
The OB1022 uses a DATA pin and a VSS pin for data interaction without specialized power supply PIN.
The OB1022 has a build-in Zener-diode for chip protection. The Small package makes it ideal for battery-pack identification and inventory tracking.
Single-Wire interface and no power supply required
1024x8 bits MTP for multiple Write/Read
Built in DATA pin clamp for chip protection
Low voltage(5V) for Programming
Simplify ROM command and Unified Write/Read flow
15KV IEC 61000-4-2 ESD compliance on DATA pin
Small surface-mount package available in 3-pin SOT-23
