SGM4591
Low Voltage 16-Bit I2C and SMBus Low-Power I/O Expander
GENERAL DESCRIPTION
FEATURES
SGM4591
Low Voltage 16-Bit I2C and SMBus Low-Power I/O Expander
GENERAL DESCRIPTION
The SGM4591 is a general-purpose parallel input and output (I/O) expander device, which consists of two lanes and 8 bits parallel I/O expansion. The device communicates with processor through two-line bidirectional I2C bus (or SMBus), supporting I2C standard mode (100kHz) and I2C fast mode (400kHz) clock frequency. The SGM4591 provides a simple solution for the devices that need additional I/Os, such as LEDs, buttons, sensors, etc.
The SGM4591 can select device address by the A0 and A1 pins. The SGM4591 features an interrupt generated on the nINT whenever the state of input port changes. An output anomaly may also be indicated by the nINT pin when the corresponding Output Anomaly Indication port register is set to 1 and the device is in push-pull output mode. The SGM4591 can cycle the power supply and cause a power-on reset to reset itself to the default state. In addition, the device can use a hardware nRESET pin to reset itself to the default state.
The SGM4591 is available in Green TSSOP-24 and TQFN-4×4-24FL packages and supports -40 °C to +125°C temperature range.

SGM4591
低電壓 16 位元 I2C/SMBus 低功耗 I/O 擴充器
產品說明
SGM4591 為一款通用型並列輸入/輸出擴充器,內部包含兩組通道,提供 16 位元並列 I/O 擴充能力。裝置透過雙線雙向 I2C 匯流排或 SMBus 與處理器通訊,支援 100kHz 標準模式與 400kHz 快速模式時脈,能為需要額外 I/O 的系統提供簡單且有效的擴充方案,例如 LED、按鍵及感測器等應用。
SGM4591 可透過 A0 與 A1 腳位進行裝置位址設定。當任一輸入埠狀態發生變化時,會透過 nINT 腳位產生中斷訊號;在推挽式輸出模式下,若對應的輸出異常指示暫存器設定為啟用,輸出異常亦可由 nINT 腳位顯示。裝置支援電源循環復位,可於上電時自動回復至預設狀態,亦可透過硬體 nRESET 腳位強制重設至預設狀態。
SGM4591 提供符合環保規範的 Green TSSOP-24 與 TQFN-4×4-24FL 封裝,可在 −40°C 至 +125°C 的溫度範圍內穩定運作。
