The MSC1211/12/13/14 are completely integrated families of mixed-signal devices incorporating a high-resolution delta-sigma () ADC, 16-bit DACs, 8-channel multiplexer, burnout detect current sources, selectable buffered input, offset DAC, Programmable Gain Amplifier (PGA), temperature sensor, voltage reference, 8-bit microcontroller, Flash Program Memory, Flash Data Memory, and Data SRAM.
On-chip peripherals include an additional 32-bit accumulator, an SPI-compatible serial port with FIFO, dual USARTs, multiple digital input/output ports, a watchdog timer, low-voltage detect, on-chip power-on reset, 16-bit PWM, breakpoints, brownout reset, three timer/counters, and a system clock divider. The MSC1211 and MSC1213 also contain a hardware I2C peripheral.
The devices accept low-level differential or single-ended signals directly from a transducer. The ADC provides 24 bits of resolution and 24 bits 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 conversion.
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 devices at a lower external clock frequency and achieve the same performance at lower power than the standard 8051 core.
The MSC1211/12/13/14 allow users to uniquely configure the Flash and SRAM memory maps to meet the needs of their applications. The Flash is programmable down to 2.7V using both serial and parallel programming methods. The Flash endurance is 100k Erase/Write cycles. In addition, 1280 bytes of RAM are incorporated on-chip.
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 each part is typically less than 4mW. The MSC1211/12/13/14 are all available in a TQFP-64 package.
The MSC1211/12/13/14 are designed for high-resolution measurement applications in smart transmitters, industrial process control, weigh scales, chromatography, and portable instrumentation.
