- Support secure communications for IoT
products such as wearables and small devices that use coin
batteries -
Toshiba Corporation's (TOKYO:6502) Storage & Electronic
Devices Solutions Company today announced the launch of two new
ICs, “TC3567CFSG” and “TC3567DFSG,” that match industry leading [1]
low current consumption realized by previous products[2] while
offering an enhanced security function. The new ICs are the latest
additions to Toshiba’s line-up of ICs supporting Bluetooth® Low
Energy (LE)[3] ver.4.2 communications. Sample shipments start
today.

The new ICs, like previous products, realize a peak current
consumption of 3.3mA at 3V voltage supply in transmission mode by
adopting a highly efficient DC-DC converter and an original
low-power circuit design. They are also able to acquire a random
number with a length of up to 32 bytes, using a random number
generator, newly incorporated as hardware, a function that will
help to strengthen the information security of IoT products.
“TC3567CFSG” incorporates of 128KB Flash ROM for storing user
programs and various data in stand-alone operations, and can
execute an approximately 50KB application program at maximum. As in
the previous products, integration of an RF matching circuit and
crystal load capacitors for a clock generator reduce the external
component count during IC design, and in the minimal case only
seven components are required for set development. This contributes
to reductions in cost and mounting area.
“TC3567DFSG” has no built-in Flash ROM and achieves extremely
low current operation by reducing the current consumption required
for access to Flash ROM. This allows it to achieve long operating
times for applications powered by small coin batteries. For
example, using a CR2032 type coin battery, the new IC can carry out
beacon operation for over two years[4].
The new ICs will facilitate adoption of Bluetooth® LE
communications for IoT products that require 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 optimizing
product value.
