LAS VEGAS — Toshiba announced three new products at this year’s CES show. EDN.com meet with Deepak Mithani, director of Mixed Signal Business Unit, to learn more about their latest products.
Toshiba's new products aid in mobile connectivity.
The first new product is a higher power wireless charger IC under the Qi standard. This new solution adds a 12W solution to Toshiba’s existing 5W solution. The new component will be for charging tablets.

Toshiba's 12W wireless charging diagram below shows a neat and simple architecture. In addition to charging a device properly, an external apps processor can access a product ID code or other information from the receiving device (see the green “Information” arrow in the diagram).
The next, Toshiba announced a data center fan system reference design. Data centers have plenty of heat nowadays with the high speed handling of volumes of data. An efficient, sophisticated, yet low cost fan system is sorely needed. Toshiba engineers have supplied the architecture in this reference design.
The fan control reference design for servers and data centers is built around the Toshiba TMPM375 microcontroller (MCU) with unique Vector Engine (VE) technology and peripherals to greatly simplify complex motor control designs in high-performance cooling fans and similar products.
Mithani told EDN:
Our cooling fan reference design demonstrates advanced vector motor control methods implemented in a space- and cost-efficient solution, enhancing power efficiency, reducing noise level and improving the overall operating cost of data center systems.
Toshiba’s approach to improving motor controls is the implementation of specific hardware accelerators within its MCU products. The company says its VE technology employs vector control in hardware to aid in handling of complex field-oriented vector control and space-vector modulation methods, which it says greatly reduces system processor loading compared to DSP- or FPGA-based vector control, while delivering highly precise, efficient, and quiet motor operations.
Toshiba components make up the electronics control system for the data center fan reference design. Each motor driver has its own MCU in a single module.
Vector control architectures were long considered cost-prohibitive because of the computational power requirements, software complexity, and associated hardware cost. Modern processor and custom accelerator technologies have emerged, enabling affordable solutions to these challenges.
The ARM Cortex-M3 core-based TMPM375FSDMG includes an advanced Vector Control hardware design that lowers system cost for field-oriented control. It features a very small footprint SS0P30 package (7.6×10 mm), reduced component count (since it does not require analog front end), high-speed operation (25ns PWM), and extended temperature range (-40 to +105°C). Combining the TMPM375FSDMG with the peripheral components and tools in the reference design should benefit designers by accelerating time to market and reducing software development effort.
The third new announcement is a TC35670-based Beacon Reference Design with Bluetooth Low Energy (BLE) and NFC Tag in one IC package.
The TC35670 reference system comprises an ultra-low-power BLE component, a best-in-class NFC Type 3 Tag, and complete system software.
Mithani told EDN that beacons represent a valuable opportunity for commercial locations to connect with consumers in a variety of settings, such as retail shopping environments or through products used in the home, such as high-function remote controls.
Toshiba’s TC35670 reference model enables devices to remain in nearly zero power standby, with wakeup mode being engaged either by the built-in microprocessor’s 6-axis sensor or by a reader coming into proximity with the NFC Tag subsystem.
Custom software is implemented in the built-in 512Kbit EEPROM, enabling a high degree of configurability, such as modifying Bluetooth parameters (e.g., advertising interval, transmit power, beacon ID3) from the NFC Tag.
The solution is in a 75×35×12mm case, and the reference model also includes the BLE RF block and NFC Tag analog and logic blocks; BLE and NFC antennas; UART, I2C, SPI, PWM, GPIO and JTAG interface blocks; SRAM and MROM blocks; and ADC and DC-DC converters. Power is supplied by a CR2032 coin battery.
