Toshiba TB9033FTG Automotive CXPI Responder Interface IC

Toshiba TB9033FTG Automotive Clock Extension Peripheral Interface (CXPI) Responder Interface IC features built-in hardware logics, which control transmission and reception by the CXPI protocol and general-purpose input/output (GPIO). This design eliminates the need to create dedicated software, helping to reduce product development times. The TB9033FTG offers 16 GPIO pins. Six can be switched to AD converter input, and four to pulse width modulation (PWM) output. The IC includes functions that enable use in automotive applications, including input monitoring during sleep mode, output during a communications disruption, and switch matrix (max 4x4) input. Fault detection circuits are integrated for overheating, overvoltage, and low voltage. The module also detects conditions that precede an abnormality and sends the data to the commander node for improved performance.

Toshiba TB9033FTG interface IC conforms to the CXPI standard for automotive communications protocols and will conform to the AEC-Q100 qualification standard. This CXPI responder interface IC is ideal for body control system applications, such as steering wheel switches, meter cluster switches, light switches, and door locks and mirrors.

Features

  • Responder interface IC conforming to CXPI standard for automotive communications protocols
