MSC1200Y3 Datasheet PDF - TI

The MSC1200Yx, MSC1201Yx, and MSC1202Yx are completely integrated families of mixed-signal devices incorporating a high-resolution, delta-sigma ADC, 8-bit cuurent output DAC, input multiplexer, burnout detect current sources, selectable buffered input, offset DAC, programmable gain amplifier (PGA), temperature sensor, voltage reference, 8-bit 8051 microcontroller, Flash Program Memory, Flash Data Memory, and Data SRAM. The MSC1200, MSC1201, and MSC1202 will be referred to as the MSC120x in this document, unless otherwise noted.

●On-chip peripherals include an additional 32-bit summation register, basic SPI, basic I2C, USART, two 8-bit digital input/output ports, a watchdog timer, low-voltage detect, on-chip power-on reset, brownout reset, timer/counters, system clock divider, PLL, on-chip oscillator, and external or internal interrupts.

●The devices accept differential or single-ended signals directly from a transducer. The ADC provides 24 bits (MSC1200/01) or 16 bits (MSC1202) of resolution and 24 bits (MSC1200/01) or 16 bits (MSC1202) of no-missing-code performance using a Sinc3 filter with a programmable sample rate. The ADC also has a selectable filter that allows for high-resolution, single-cycle conversions.

●The microcontroller core is 8051 instruction set compatible. The microcontroller core is an optimized 8051 core that executes up to three times faster than the standard 8051 core, given the same clock source. This design makes it possible to run the device at a lower external clock frequency and achieve the same performance at lower power than the standard 8051 core.

●The MSC120x allow users to uniquely configure the Flash Memory map to meet the needs of their applications. The Flash is programmable down to +2.7V using serial programming. Flash endurance is typically 1M Erase/Write cycles.

●The parts have separate analog and digital supplies, which can be independently powered from +2.7V to +5.25V. At +3V operation, the power dissipation for the part is typically less than 3mW. The MSC1200 is available in a TQFP-48 package. The MSC1201 and MSC1202 are both available in a QFN-36 package.

●The MSC120x are designed for high-resolution measurement applications in smart transmitters, industrial process control, weigh scales, chromatography, and portable instrumentation.
