Toshiba Semiconductor and Storage Products announced two new "TC3567CFSG" and "TC3567DFSG" leading industry [1] to achieve lower current consumption than the plateau [2] and enhance the safety communication function. These two ICs are Toshiba's latest members of Bluetooth-enabled low power (LE) [3] ver.4.2 communication chips. The sample is available.
"TC3567CFSG" contains 128KB of flash memory for storing user programs and data in standalone work operations, up to approximately 50KB of applications. Like the previous generation, the crystal load capacitance of the clock oscillator and wireless matching circuit is integrated to reduce the number of external components required to design the wafer during the design. In the most streamlined case, only seven components outside the IC and the IC will be able to work properly. Significantly reduce costs and board area.
"TC3567DFSG" no built-in flash memory, the use of reduced access to flash memory required current consumption, to achieve very low current operation. This chip for a small button battery-powered applications to achieve longer operating time. Such as the use of CR2032 button battery, which can be more than two years of communication operations [4].
The new IC uses a highly efficient DC-DC converter and a low-power circuit design, which achieves 3.3mA peak current consumption in the 3V voltage supply outside the Bluetooth transmission mode. But also to enhance the safety of Bluetooth communications, IoT products for high security needs, including wearing equipment for medical care applications and a variety of small devices such as sensors and toys for button batteries.
