Data Acquisition System Single ADC Dual DAC 24-Bit 64-Pin TQFP T/R

The MSC1213 are completely integratedfamilies of mixed-signal devices incorporating ahigh-resolution delta-sigma (?S) ADC, 16-bit DACs,8-channel multiplexer, burnout detect current sources,selectable buffered input, offset DAC, Programmable GainAmplifier (PGA), temperature sensor, voltage reference,8-bit microcontroller, Flash Program Memory, Flash DataMemory, and Data SRAM, as shown in Figure 8.On-chip peripherals include an additional 32-bitaccumulator, an SPI-compatible serial port with FIFO, dualUSARTs, multiple digital input/output ports, a watchdogtimer, low-voltage detect, on-chip power-on reset, 16-bitPWM, breakpoints, brownout reset, three timer/counters,and a system clock divider. The MSC1213also contain a hardware I2C peripheral.The devices accept low-level differential or single-endedsignals directly from a transducer. The ADC provides 24bits of resolution and 24 bits of no-missing-codeperformance using a Sinc3 filter with a programmablesample rate. The ADC also has a selectable filter thatallows for high-resolution, single-cycle conversion.The microcontroller core is 8051 instruction setcompatible. The microcontroller core is an optimized 8051core that executes up to three times faster than thestandard 8051 core, given the same clock source. Thisdesign makes it possible to run the devices at a lowerexternal clock frequency and achieve the sameperformance at lower power than the standard 8051 core.The MSC1213 allow users to uniquely configure theFlash and SRAM memory maps to meet the needs of theirapplications. The Flash is programmable down to 2.7V usingboth serial and parallel programming methods. The Flashendurance is 100k Erase/Write cycles. In addition, 1280bytes of RAM are incorporated on-chip.The parts have separate analog and digital supplies, whichcan be independently powered from 2.7V to +5.25V.At +3V operation, the power dissipation for each part istypically less than 4mW. The MSC1213 are allavailable in a TQFP-64 package.The MSC1213 are designed for high-resolutionmeasurement applications in smart transmitters, industrialprocess control, weigh scales, chromatography, andportable instrumentation.
