Toshiba Offers BLE IC for Automotive Applications

Toshiba Electronic Devices & Storage Corp. has announced a new integrated circuit compliant with Bluetooth Low Energy (BLE) core specification 4.2, including support for secure connection, LE privacy features and extended packet length support. It is available for use in harsh automotive environments and extended temperature ranges. The mixed-signal TC35679IFTG contains both analog RF and baseband digital parts to provide a complete solution in a single, compact and low-profile, 40-pin 6-millimeter by 6-millimeter by 1-millimeter QFN "wettable flank" package, with a pin pitch of 0.5 millimeter.

The TC35679IFTG provides Bluetooth host control interface (HCI) functions alongside low-energy GATT profile functions (as defined by Bluetooth) specifications. The new IC becomes an application processor when used in conjunction with external non-volatile memory, or can be used in combination with an external host processor.

The integrated device is based on an Arm Cortex-M0 processor. It includes 384 kilobytes of on-board mask ROM to support the Bluetooth baseband process and 192 kilobytes of on-board RAM for Bluetooth application programs and data.

A key feature of the TC35679IFTG is its ability to form part of sophisticated systems as a result of 17 general-purpose input-output (GPIO) lines and multiple communications options. The GPIO lines offer access to a range of on-chip features, including a wake-up interface, a four-channel PWM interface and a six-channel AD converter. On-chip DC-DC converter or LDO circuits adjust the external voltage supply to the required values on chip.

Designed for compliance with AEC-Q100, the low-energy IC is primarily intended for use in automotive applications. The wettable flank package simplifies automatic visual inspection needed to deliver the high levels of soldering quality required to withstand vibration experienced in automotive applications.

Current applications include remote key systems and reducing cables by providing a reliable wireless connection to sensors. The device will also facilitate remote connection to diagnostic equipment, creating a Bluetooth on-board diagnostic (OBD) port, thereby saving the cost and weight of the associated cabling and OBD connector.

The TC35679 accepts a wide range of supply voltages (1.8 volts to 3.6 volts), making it suitable for automotive applications. The operating temperature range is -40 degrees to +105 degrees Celsius for input voltages from 2.7 volts to 3.6 volts, and -40 degrees to +85 degrees Celsius from 1.8 volts to 3.6 volts.
