- What Is a Mixed-Signal Controller ?
The term "mixed-signal" means an integrated circuit that contains both analog and digital circuit elements. Toshiba's mixed-signal controller incorporates a CPU on the same chip to allow adjustment of the characteristics of on-chip analog circuits.
The market of Micro Electro Mechanical System (MEMS) sensors is growing rapidly, with many applications being introduced one after another. The mixed-signal controller is specifically designed to address such needs by integrating peripheral circuits on the same chip. Embedded software for the controller simplifies sensor calibration, and the integrated peripheral circuits reduce board component count.
- Combination of Analog Circuits and Embedded Software
Embedded software is executed by the CPU and peripheral functions such as a timer and a serial I/O, whereas the integrated analog circuits such as an op amp, multiplexer and lowpass filter capture analog data from various sensor devices.
The mixed-signal controller offers a solution for incorporating even the main MCU on the same chip.

Future Roadmap for Sensor Support
Toshiba is planning to develop mixed-signal controllers for a wide variety of sensors, including products in compact packages highly demanded by sensor applications. Sample software will also be made available.
Bare die products can be supplied as well as packaged products. By integrating sensor devices and an MCU in a single package, Toshiba's mixed-signal controller helps develop an intelligent sensor. Toshiba is dedicated to delivering the best solutions for your needs by supporting application-specific customization and software development.
Software Development Support
Toshiba offers a suite of sample software that can be commonly used for various sensors (such as automatic offset calibration and averaging routines). Toshiba also provides application software for specific types of sensor (e.g., tilt sensing, vibration sensing, etc. for acceleration sensors). For details, contact your nearest Toshiba sales representative.
The software running on the TMP89FH00 calibrates sensor data and translates it into a digital form so that the PC can display sensor data without processing it in any way. Additionally, the PC can issue simple data manipulation instructions to the TMP89FH00; thus sensor data can be adjusted on the starter kit side according to the sensor connected. You can also collect logs while viewing a waveform display at the same time.
Toshiba offers a starter kit for sensor applications that contains a mixed-signal controller with the TMP89FH00 microcontroller with preloaded software. The starter kit board has a connector for attaching a variety of sensors. You can verify the operation of the TMP89FH00 on a PC by connecting the board via a USB cable.
