产品信息
描述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.特性ANALOG FEATURES 24-Bits No Missing Codes 22-Bits Effective Resolution At 10Hz Low Noise: 75nV PGA from 1 to 128 Precision On-Chip Voltage Reference Accuracy: 0.2% Drift: 5ppm/°C 8 Differential/Single-Ended Channels On-Chip Offset/Gain Calibration Offset Drift: 0.1ppm/°C Gain Drift: 0.5ppm/°C On-Chip Temperature Sensor Selectable Buffer Input Burnout Detect 16-Bit Monotonic Voltage DACS: Quad Voltage DACs (MSC1211, MSC1212) Dual Voltage DACs (MSC1213, MSC1214) DIGITAL FEATURES Microcontroller Core 8051-Compatible High-Speed Core 4 Clocks per Instruction Cycle DC to 40MHz at +85°C Single Instruction 100ns Dual Data Pointer Memory Up To 32kb Flash Memory Flash Memory Partitioning Endurance 1M Erase/Write Cycles, 100-Year Data Retention In-system Serially Programmable External Program/Data Memory (64kB) 1,280 Bytes Data SRAM Flash Memory Security 2kB Boot ROM Programmable Wait State Control Peripheral Features 34 I/O Pins Additional 32-Bit Accumulator Three 16-Bit Timer/Counters System Timers Programmable Watchdog Timer Full-Duplex Dual USARTs Master/Slave SPI™ with DMA Multi-master I2C™ (MSC1211 and MSC1213) 16-Bit PWM Power Management Control Internal Clock Divider Idle Mode Current < 200µA Stop Mode Current < 100nA Programmable Brownout Reset Programmable Low-Voltage Detect 24 Interrupt Sources Two Hardware Breakpoints GENERAL FEATURES Pin-Compatible with MSC1210 Package: TQFP-64 Low Power: 4mW Industrial Temperature Range: 40°C to +125°C Power Supply: 2.7V to 5.25V APPLICATIONS Industrial Process Control Instrumentation Liquid/Gas Chromatography Blood Analysis Smart Transmitters Portable Instruments Weigh Scales Pressure Transducers Intelligent Sensors Portable Applications DAS SystemsI2C is a trademark of Philips corporation.
