The ADuCRF101 is a fully integrated, data acquisition solution that is designed for low power, wireless applications. It features a 12-bit analog-to-digital converter (ADC), a low power ARM Cortex?-M3 processor, a 862 MHz to 928 MHz and 431 MHz to 464 MHz RF transceiver, and Flash?/EE memory. The ADuCRF101 is packaged in a 9 mm ? 9 mm LFCSP.The data acquisition section consists of a 12-bit SAR ADC. The six inputs can be configured in single-ended or differential mode. When configured in single-ended mode, they can be used for ratiometric measurements on sensors that are powered, when required, from the internal low dropout regulator (LDO). An internal battery monitor channel and an on-chip temperature sensor are also available.This wireless data acquisition system is designed to operate in battery-powered applications where low power is critical. The device can be configured in normal operating mode or different low power modes under direct program control. In flexi mode, any peripheral can wake up the device and operate it. In hibernate mode, the internal wake-up timer remains active. In shutdown mode, only an external interrupt can wake up the device.The ADuCRF101 integrates a low power ARM Cortex-M3 processor. It is a 32-bit RISC machine, offering up to 1.25 DMIPS peak performance. The ARM Cortex-M3 processor also has a flexible 14-channel direct memory access (DMA) controller that supports communication peripherals, serial peripheral interface (SPI), UART, and I2C. Also provided on chip are 128 kB of nonvolatile Flash/EE memory and 16 kB of SRAM.A 16 MHz on-chip oscillator generates the system clock. This clock can be internally divided for the processor to operate at a lower frequency, thus saving power. A low power, internal 32 kHz oscillator is available and can be used to clock the four timers, as follows: two general-purpose timers, a wake-up timer, and a system watchdog timer.A range of communication peripherals can be configured, as required, in a specific application. These peripherals include UART, I2C, SPI, GPIO ports, PWM, and RF transceivers.The RF transceiver communicates in the 862 MHz to 928 MHz and 431 MHz to 464 MHz frequency bands using multiple configurations.On-chip factory firmware supports in-circuit serial download via the UART, and nonintrusive emulation and program download are also supported via the serial wire interface. These features are incorporated into a low cost development system supporting this precision analog microcontroller family.The ADuCRF101 operates from 2.2 V to 3.6 V and is specified over an industrial temperature range of ?40?C to +85?C. It is available in a 64-lead LFCSP packageApplications Battery powered wireless sensor Medical telemetry systems Industrial and home automation Asset tracking Security systems (access systems) Health and fitness applications??

The ADuC832 is a complete, smart transducer front end, integrating a high performance self-calibrating multichannel 12-bit ADC, dual 12-bit DACs, and programmable 8-bit MCU on a single chip.The device operates from a 32 kHz crystal with an on-chip PLL, generating a high frequency clock of 16.78 MHz. This clock is, in turn, routed through a programmable clock divider from which the MCU core clock operating frequency is generated. The microcontroller core is an 8052 and is therefore 8051 instruction set compatible with 12 core clock periods per machine cycle. 62 kB of nonvolatile Flash/EE program memory are provided on chip. There are also 4 kB of nonvolatile Flash/EE data memory, 256 bytes of RAM, and 2 kB of extended RAM integrated on chip.The ADuC832 also incorporates additional analog functionality with two 12-bit DACs, a power supply monitor, and a band gap reference. On-chip digital peripherals include two 16-bit Σ-Δ DACs, a dual-output 16-bit PWM, a watchdog timer, timeinterval counter, three timers/counters, Timer 3 for baud rate generation, and serial I/O ports (SPI, I2C®, and UART).Applications Optical networking—laser power control Base station systems Precision instrumentation, smart sensors Transient capture systems DAS and communications systems Upgrade to ADuC812 systems; runs from 32 kHz External crystal with on-chip PLL.

The ADuC841/ADuC842/ADuC843 are complete smart transducer front ends, that integrates a high performance self-calibrating multichannel ADC, a dual DAC, and an optimized single-cycle 20 MHz 8-bit MCU (8051 instruction set compatible)on a single chip.The ADuC841 and ADuC842 are identical with the exception of the clock oscillator circuit; the ADuC841 is clocked directly from an external crystal up to 20 MHz whereas the ADuC842 uses a 32 kHz crystal with an on-chip PLL generating a programmable core clock up to 16.78 MHz.The ADuC843 is identical to the ADuC842 except that the ADuC843 has no analog DAC outputs.The microcontroller is an optimized 8052 core offering up to 20 MIPS peak performance. Three different memory options are available offering up to 62 kBytes of nonvolatile Flash/EE program memory. Four kBytes of nonvolatile Flash/EE data memory, 256 bytes RAM, and 2 kBytes of extended RAM are also integrated on-chip. The parts also incorporate additional analog functionality with two 12-bit DACs, power supply monitor, and a band gap reference. On-chip digital peripherals include two 16-bit Σ-Δ. DACs, a dual output 16-bit PWM, a watchdog timer, a time interval counter, three timers/counters, and three serial I/O ports (SPI, I2C, and UART).On the ADuC812 and the ADuC832, the I2C and SPI interfaces share some of the same pins. For backwards compatibility, this is also the case for the ADuC841/ADuC842/ADuC843.However, there is also the option to allow SPI operate separately on P3.3, P3.4, and P3.5, while I2C uses the standard pins. The I2C interface has also been enhanced to offer repeated start, general call, and quad addressing.On-chip factory firmware supports in-circuit serial download and debug modes (via UART) as well as single-pin emulation mode via the EA pin..Applications Optical networking—laser power control Base station systems Precision instrumentation, smart sensors Transient capture systems DAS and communications systems
