Toshiba's Bluetooth 5 ICs for beacon tags

Toshiba launched new TC35680FSG (featuring built-in flash memory) and TC35681FSG ICs compliant with the Bluetooth low energy standard . The new TC35680FSG and TC35681FSG suggested for beacon tags, IoT devices and industrial equipment. Sample shipments will begin later this month.

TC35680FSG and TC35681FSG support the full spectrum of data rates required for the high-speed features – 2M PHY and Coded PHY (500kbps and 125kbps) of Bluetooth 5.0. These ICs feature receiver sensitivity level of -105dBm (at125kbps )2 and a built-in high efficiency power amplifier in the transmission block that provides up to +8 dBm transmission power.

Both are powered by ARM Cortex-M0 processor with 256KB Mask ROM to support the Bluetooth baseband process, and 144KB of RAM for processing Bluetooth baseband, stack and data.

TC35680FSG and TC35681FSG also feature 18-port GPIOs as interfaces, which can be set to 2 channels each for SPIs, I2C, and UART. This allows for the structuring of systems that connect to various peripheral devices. These GPIOs can be set for a wakeup function, 4-channel PWM, 5-channel AD converter interfaces, an external amplifier control interface for long-range communication, and more.

The TC35680FSG includes 128KB4 of flash memory for storing user programs and various data in stand-alone operations, making it well-suited to a wide range of applications and removing the need for external non-volatile memory. This also lowers the part count, which reduces both the cost and mounting area.

The TC35681FSG, which does not include a built-in flash memory, operates in conjunction with an external non-volatile memory or host processor. A wide operating range of -40° to +125°C makes it suitable for applications exposed to high temperatures.
