Toshiba’s new ICs for bluetooth® smart devices

Toshiba Electronics Europe has announced the launch of two new ICs - TC3567CFSG and TC3567DFSG.

The latest additions to the company’s line-up of high-performance devices supporting Bluetooth® Low Energy [3] ver.4.2 communications match the industry-leading[1] low current consumption delivered by its previous products[2] while also offering enhanced security functionality.

Both ICs realize a peak current consumption of just 3.3mA at 3V supply when in transmission mode, through use of a highly efficient DC-DC converter and an extremely effective proprietary low-power circuit design. From a security perspective they are able to acquire a random number with a length of up to 32B, using a random number generator. This function will help to strengthen the protection of information in IoT application.

TC3567CFSG comprises a 128KB Flash ROM for storing user programs and various other forms of data in stand-alone operations, and can execute application programs of up to 50KB in size. As in the previous products, integration of an RF matching circuit and crystal load capacitors for timing purposes help to reduce the external component count for board level designs, with as little as seven peripheral components being required. This contributes to marked reductions in bill-of-materials costs and the PCB area utilised.

As the TC3567DFSG has no built-in Flash ROM it is able to achieve even lower power budgets. This means that it can support longer operating times for applications powered by small coin batteries. For example, using a CR2032 type coin battery, this IC can carry out beacon operation for a period of over two years[4].

The new ICs will aid the adoption of Bluetooth® LE in IoT products requiring a high level of security, including wearable devices for healthcare applications and high-grade small devices that use coin batteries, such as sensors and toys. They will support set makers in optimising product value.

Samples for both devices are now available.
