1.5K-Bit Serial EPROM With SDQ Interface

Check for Samples: bq2026

FEATURES

DESCRIPTION

The bq2026 is a 1.5K-bit serial EPROM containing a

factory-programmed, unique 48-bit identification

number, 8-bit family code, and a 64-bit status

•

1536 bits of One-Time Programmable (OTP)

EPROM For Storage Of User-Programmable

Configuration Data

•

Factory-Programmed Unique 64-Bit

Identification Number

The bq2026 SDQ™ interface requires only a single

connection and a ground return. The SDQ pin is also

the sole power source for the bq2026.

Single-Wire Interface to Reduce Circuit Board

Routing

The small surface-mount package options saves

printed-circuit-board space, while the low cost makes

it ideal for applications such as battery pack

configuration parameters, record maintenance, asset

tracking, product-revision status, and access-code

security.

Synchronous Communication Reduces Host

Interrupt Overhead

6KV IEC 61000-4-2 ESD Compliance on Data

•

No Standby Power Required

Available in a 3-Pin SOT23 Package and TO-92
