PCU9669B,118 Description

Short technical summary and product information.

The PCU9669B,118 is a fourth-generation I2C-bus controller designed for data-intensive transfers. It offers three independent I2C-bus channels: one with Fast-mode Plus (Fm+) capability up to 1 Mbit/s and two with Ultra Fast-mode (UFm) up to 5 Mbit/s. Each channel is equipped with a 4352-byte data buffer, totaling 13056 bytes of buffer space, minimizing CPU interruptions.

 

This controller functions as an 8-bit parallel-bus to I2C-bus protocol converter. It can manage up to 64 slaves in a single sequence without CPU intervention and includes a sequence loop control feature for automatic retransmission. The onboard oscillator and PLL generate necessary clocks, reducing CPU overhead. An external trigger input allows synchronization with external events, controlling the retransmission rate of stored sequences.

 

Error reporting is handled at transaction, channel, and controller levels with maskable interrupts for customization. The parallel bus interface operates at 3.3V, while the I2C-bus I/O logic levels are referenced to a VDD(IO) pin ranging from 3.0V to 5.5V. The device operates within a temperature range of -40°C to 85°C and is supplied in a 48-LQFP package.
