Serial Controller Interface

Overview

Inicore’s iniSCI Slave is a synthesizable, flexible, and structured VHDL implementation of a Serial Controller Interface (SCI) that uses a two-wire bus for communicating between integrated circuits or standard peripherals like smart LCDs and keypads.

The iniSCI Slave complies with the definition of the ‘Inter-Integrated Circuit Bus’ (I2C). It is intended to be used as an interface block between the I2C buslines (SDA,SCL) and two mailbox memories. A local Mail-bus interface consisting of data, address and control lines allows you to interface registers or RAM’s up to a size of 256 bytes.

The iniSCI Slave contains the entire physical and data link layers, allowing to handle bus timing and frame generation/extraction, and thus reducing overhead from the system application.

INICORE’s strategy is not to compete with the standard chip manufacturers, but to use the ASIC and FPGA technologies for `system on chip’ design, which demands standards like I2C with customer specific user functions.

Benefits

iniSCI is modular structured into a BitSync bus interface, receiver, transmitter, and framer modules. This modular structure facilitates an understanding of the core’s functionality, thus simplifying customization.
