Drop-in Bluetooth 4.0 module-on-module for control systems

September 11, 2014 // By Graham Prophet
Toshiba has a development module-on-module (or “Module2”) that combines a Bluetooth 4.0 module with a microcontroller in order to shorten development times. The Module2 enables simple integration into sensor control systems, lighting and heating systems, PC peripheral systems and legacy host control systems.

The Module2 measures 25 x 17 mm and is suited for battery driven applications. It comprises a Toshiba TMPM395FWAXBG ARM Cortex M3 core MCU along with a Panasonic PAN1026 Bluetooth 4.0 dual mode module, with antenna, that incorporates a Toshiba TC35661-501 Bluetooth LSI with embedded Bluetooth stack and SPP and BLE Gatt profiles.

The Bluetooth module is programmable using high-level Bluetooth APIs and includes 128 kB NAND flash memory to store the Bluetooth host control and system application software. The device supports a range of hardware interfaces including UART, I2C, SPI and JTAG debugger interface. With pre-certified Bluetooth hardware and firmware, the module provides a simple path to Bluetooth SIG EPL listing.

The MCU is bvased on an ARM Cortex M3 CPU core with an operating frequency of 20 MHz, 128 MB of internal ROM and 8 kB of internal RAM. It has independent RTC and IO capable of separating or shutting off power supplies and operates down to 1.8V. Toshiba will supply samples, full BoM and circuit diagrams to volume customers, as well as allowing them to utilise the design.
