Toshiba Is Sampling an Automotive CXPI Responder Interface IC that Con…

KAWASAKI, JAPAN--(Business Wire / Korea Newswire)--Toshiba Electronic Devices & Storage Corporation (“Toshiba”) has today started to provide samples of “TB9033FTG,” an automotive Clock Extension Peripheral Interface[2] (CXPI) responder interface IC that conforms to the CXPI standard for automotive communications protocols.

TB9033FTG is the industry’s first[1] IC of its type with built-in hardware logics[3], which control transmission and reception by the CXPI protocol and general purpose input/output (GPIO). This eliminates the need for development of dedicated software and contributes to shorter product development times.

The new IC has 16 GPIO pins. Six can be switched to AD converter input, and four to pulse width modulation (PWM) output. It also integrates functions that allow use in a broad spectrum of automotive applications: input monitoring during Sleep Mode; switch matrix (max 4×4) input; and output in the event of communications disruption.

Fault detection circuits for overheat, overvoltage and low voltage are built into the IC. It also can detect conditions that precede an abnormality and send the data to the commander node, improving fault detection performance in automotive applications.

The operating temperature range is from -40 to 125°C which is suitable for automotive applications, and the IC will conform to the AEC-Q100 qualification standard for automotive electronics.

The new product’s support for multiplexing automotive communications and reducing the number of wire harnesses used in body control systems will contribute to lower vehicle weight.

Toshiba is also developing an automotive CXPI communications driver receiver IC “TB9032FNG” that can be switched between commander node and responder node via an external pin.

Notes:

[1] As CXPI interface IC for responder nodes. As of September 3, 2024, Toshiba survey.
[2] CXPI (Clock Extension Peripheral Interface): A communications standard, developed in Japan for automotive sub-networks derived from LIN[4].
[3] Logic circuits configured with hardware without a microcontroller.
[4] LIN (Local Interconnect Network): A communications standard for lower-cost, lower-speed on-board subnetworks than provided by CAN[5].
[5] CAN (Controller Area Network): A serial communications standard, primarily used for automotive communications networks.
