PCA9500BS,118 Description

Short technical summary and product information.

The PCA9500BS,118 is an 8-bit I/O expander with an integrated 2-kbit EEPROM, designed by NXP Semiconductors. This device offers eight quasi-bidirectional data pins that can be independently configured as inputs or outputs, suitable for monitoring board status or controlling indicator devices like LEDs.

 

Key features include an I2C-bus and SMBus interface logic, operating voltage range of 2.5 V to 3.6 V, and a clock frequency of up to 400 kHz. The integrated EEPROM can store board manufacturing data or error codes for diagnostic purposes. The PCA9500BS,118 supports hot insertion, making it useful for removable card systems.

 

This I/O expander is supplied in a 16-HVQFN (4x4) package, designed for surface mounting. It operates within a temperature range of -40°C to 85°C. The device is a drop-in replacement for the PCF8574, offering enhanced functionality with its integrated EEPROM.

 

Applications include board version tracking, status reporting, multi-card systems in telecommunications, and general-purpose I/O expansion with memory.
