Get quickly into Bluetooth LE with starter kit

October 01, 2014 // By Graham Prophet
Toshiba Electronics has a starter kit that will help shorten development times when creating Bluetooth Low Energy (BLE) subsystems. The kit features a Toshiba BLE IC and microcontroller, hosted on separate printed circuit boards, together with sensors and the associated software development tools necessary to simplify system creation.

Toshiba's TC35667FTG BLE IC is a low-power circuit design and integrates a highly efficient DC-DC converter, reducing peak current consumption to below 6 mA and deep sleep current consumption to below 100 nA. The receiver has a sensitivity of -91 dBm and transmitter output power can be varied from 0 dBm to -20 dBm in 4 dB steps. In addition to the TC35667FTG, the BLE daughter board contains two oscillators (26 MHz and 32.7 kHz), 512 kbit EEPROM, a PCB antenna and an RF connector for connection to RF testers.

The mother board is based around a TMPM395FWAXBG microcontroller using an ARM Cortex-M3 CPU core with an operating frequency of 20 MHz, 128 kB of internal ROM and 8 kB of internal RAM. The MCU has an independent RTC and IO capable of shutting off power supplies and supports low power operation at 1.8V. The board also houses a thermal sensor, accelerometer and buzzer, and has GPIO, JTAG and USB interfaces.

Integrated development environments (IDEs) from Keil and IAR Systems are usable with the starter kit enabling software debugging and testing to be conducted via the JTAG interface. Sample application source codes are also available together with a high level API software driver.
