Digital signal controller
powers inertial sensor
BEI Systron Donner Inertial Division has used TI's TMS320F2812 digital signal controller in its micro-electromechanical systems inertial measurement unit, the MMQ-50
BEI Systron Donner Inertial Division (SDID) has selected TI's TMS320F2812 digital signal controller for its micro-electromechanical systems (MEMS) inertial measurement unit (IMU), the MMQ-50. The F2812 is a highly integrated embedded controller that combines TI's leading DSP technology for 150MIPS of control-optimised processing power with the flexibility of integrated peripherals and the ease of use of a traditional microcontroller (MCU).

This combination allows the F2812 to handle both the control system processing requirements as well as the control system functions typically handled by additional host MCUs.
IMU technology is used in a number of commercial aircraft, automotive and military applications to sense the relative position of the vehicle or craft.
MEMS technology allows the miniaturisation of the IMU through the use of one piece, micromachined quartz inertial sensors that measure angular rotational velocity.
These sensors produce a signal output proportional to the rate of rotation sensed, which are converted to relative positioning information.
'The F2812 digital signal controller gave us the best combination of price, integration and size as well as the ease of configuration and programming with TI's eXpressDSP software and development tools', said Mark Chamberlain, Director of Marketing and Sales, SDID.

'The F2812 controller allowed us to leverage our automotive-based MEMS rate sensor technology into high performance aerospace and defence applications and make the MMQ-50 one of the smallest and lowest cost IMUs available on the market today'.
TI's highly integrated F2812 controllers have the processing power and small package size that enable manufacturers to build smaller designs with increased functionality and features.
The MMQ-50 IMU offers enhanced performance at a low cost and includes six full degrees of freedom sensing capability in a compact size of less than 6in3.
With an unmatched level of memory and peripheral integration, the F2812 embedded controller gives designers system-on-a-chip like benefits which greatly reduces board space and overall system cost, and leads to simpler, more cost-effective designs with higher functionality and features.
The F2812 controller integrates 128Kword of Flash memory at 110MIPS for simple reprogramming during development and in-field software updates.
Optimised event managers include pulsewidth modulation (PWM) generators, programmable general-purpose timers and glueless capture encoder interfaces.
The device also features a 12bit analogue-to-digital convertor (ADC) with a throughput of 16.7Msample/s and dual sample-and-hold, providing critical support in tight control loops.
Five different on-chip standard communication ports provide simple communication interfaces to hosts, test equipment, displays and other components.
