TI Delivers Industry's Best Performance and Value for a Precision Data Acquisition System-on-a-Chip



Integration of Analog and Digital Cores Simplifies and Enhances System Design

TUCSON, Ariz. (March 4, 2003) - Texas Instruments (TI) Incorporated (NYSE: TXN) today introduced a low-noise, low-cost data acquisition system-on-a-chip from the company's Burr-Brown product line. The device provides unparalleled system performance for demanding applications in industrial process control, portable instrumentation, and test and measurement. (See http://www.ti.com/sc04069.)

The MSC1200 integrates a 24-bit delta-sigma analog-to-digital converter (ADC), an enhanced 8051 processor core, flash memory, internal oscillator and a variety of high-performance peripherals.

"The MSC1200 offers customers a complete, low-cost mixed-signal device which successfully extends TI's innovative MicroSystem product line," said Robert Schreiber, product line manager for TI's microsystem data converter products. "The integration of the analog and digital cores allows users to customize the device to meet specific requirements, and the low price makes the MSC1200 attractive in many new applications."

The enhanced 8051 core executes up to three times faster, with lower power, than the standard 8051 core. The MSC1200 family offers two flash memory sizes with pin and function compatibility, thus allowing the customer to freely migrate between devices as their code requirements change.

The noise performance of the ADC is 75nV, better than most standalone ADCs on the market and significantly better than any comparable mixed-signal device. The ADC also has a 1kSPS sampling rate with only 3mW of power consumption.

Inside the MSC1200

The analog features consist of a 24-bit delta sigma ADC, a flexible eight-channel multiplexer, internal oscillator, PLL, burn-out detect, selectable buffered input, offset 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 include an enhanced 8051 microcontroller core with dual data pointers, two flash memory size options (4K, 8K), 128 bytes of SRAM, four I/O ports, a 32-bit accumulator/shifter, UART, two timers/counters, basic I2C interface, basic SPI interface and a watchdog timer.

Available Today

The MSC1200 is packaged in a TQFP-48 and operates on a single 2.7V to 5.25V supply. 1,000 piece pricing is based on the two flash memory size options (suggested resale pricing): MSC1200Y2 (4K) = $5.95; MSC1200Y3 (8K) = $6.45.
