The PCA9519 is a 4-channel level translating I2C-bus/SMBus repeater that enables theprocessor low voltage 2-wire serial bus to interface with standard I2C-bus or SMBus I/O.While retaining all the operating modes and features of the I2C-bus system during thelevel shifts, it also permits extension of the I2C-bus by providing bidirectional buffering forboth the data (SDA) and the clock (SCL) lines, thus enabling the I2C-bus or SMBusmaximum capacitance of 400 pF on the higher voltage side. The SDA and SCL pins areover-voltage tolerant and are high-impedance when the PCA9519 is unpowered.

PCA9519 是一個4 通道的I2C 總線/SMBus 中繼器，可以實現將低電壓兩線串行總線接口的處理器與標準的I2C 總線或SMBus I/O 相連。該中繼器在電平轉換中保持I2C 總線系統所有的模式和特點的同時，允許通過給數據總線（SDA）和時鐘總線（SCK）提供雙向緩沖區來擴展I2C 總線，從而使I2C 總線或SMBus 在高電壓下最大容限電容為400PF。SDA 和SCL 引腳具有耐壓保護功能，當PCA9519 掉電時，均呈現出高阻抗特性。

Although Stellaris microcontrollers have generous internal SRAM capabilities, certain applicationsmay have data storage requirements that exceed the 8 KB limit of the Stellaris LM3S8xx seriesdevices. Since microcontrollers do not have an external parallel data-bus, serial memory optionsmust be considered. Until recently, the ubiquitous serial EEPROM/flash device was the only serialmemory solution. The major limitations of EEPROM and flash technology are slow write speed, slowerase times, and limited write/erase endurance.Recently, serial SRAM devices have become available as a solution for high-speed dataapplications. The N256S08xxHDA series of devices, from AMI Semiconductor, offer 32 K x 8 bits oflow-power data storage, a fast Serial Peripheral Interface (SPI) serial bus, and unlimited write cycles.The parts are available in 8-pin SOIC and compact TSSOP packages.
