TUCSON, Ariz. -- Texas Instruments (TI) Incorporated (NYSE: TXN) today introduced a family of low-noise 24-bit data acquisition system solutions from the company´s Burr-Brown product line which offers the industry´s highest level of performance and integration. By incorporating high-precision analog and digital processing into a small package, the MSC1210 family is the ideal choice for high-resolution measurement applications in industrial process control, portable instrumentation, weigh scales, smart transmitters and chromatography. (See http://dataconverter.ti.com/sc02059).
The MSC1210 family integrates a 24-bit delta-sigma analog-to-digital converter (ADC) with an enhanced 8051 processor core, flash memory and a variety of high-performance on-chip peripherals to achieve unparalleled system performance -- all at 4mW power consumption. The integration of the analog and digital cores gives customers the ability to customize the device to meet their specific requirements. It would be much more costly and difficult to achieve the same level of flexibility and performance using multiple devices.
The enhanced 8051 core executes up to three times faster, with lower power, than the standard 8051 core. The MSC1210 family offers a variety of flash memory sizes with pin and function compatibility, thus allowing the customer to freely migrate between devices as their code requirements change.
In terms of analog performance, the MSC1210 family offers the industry's lowest noise performance in a mixed-signal device (75nV). Furthermore, the ADC on the MSC1210 family has a much faster sampling rate than comparable devices.
"Providing an unsurpassed level of high-performance functionality in a single chip, which was traditionally implemented with external circuitry, has positioned the MSC1210 family as the most valuable data conversion system on the market. This device will simplify the design of complex systems and reduce overall component cost," said Robert Schreiber, product line manager for TI's data acquisition system products. "The noise performance of the ADC is better than most standalone ADCs on the market and is significantly better than any comparable mixed-signal device. The enhanced 8051 core, along with the high-performance peripherals, pushes the performance envelope of the digital processing while maintaining analog signal integrity."
The analog features of the MSC1210 family consist of a 24-bit delta sigma ADC, a flexible eight-channel multiplexer, burn-out current sources, selectable buffered input, offset digital-to-analog converter (DAC), programmable gains of up to 128, selectable data output rate, programmable single-cycle settling filter, precision on-chip voltage reference or external differential voltage reference, on-chip temperature sensor, on-chip calibration, low voltage detect and brown-out reset.
The digital features of the MSC1210 family include an enhanced 8051 microcontroller core with dual data pointers, four flash memory size options (4k, 8k, 16k, 32k) -- all with external memory capability as well -- 1.2kbytes of SRAM, 34 I/O lines, an additional 32-bit accumulator/shifter, dual UARTs, three timers/counters, SPI interface with direct memory access and a watchdog timer. The four different sizes of flash memory allow the customer to optimize the memory size to their application and provide an easy migration path to larger memory sizes without having to add external memory, as required in other devices.
The MSC1210 family is packaged in a TQFP-64 and operates on a single 2.7V to 5.25V supply. Suggested resale pricing is based on the four flash memory size options (prices for 1,000 piece quantities):
- MSC1210Y2 (4K) $8.95
- MSC1210Y3 (8K) $9.50
- MSC1210Y4 (16K) $10.75
- MSC1210Y5 (32K) $12.25
