ADUC7020 and OP2177 for HART interface signal conditioning circuit

The ADuC7020 is fully integrated, 1 MSPS, 12-bit data acquisition systems incorporating high performance multichannel ADCs, 16-bit/32-bit MCUs, and Flash/EE memory on a single chip.
The OP2177/OP1177 is the fourth generation of ADI., industry-standard OP07 amplifier family. OP2177 is a high precision, low noise operational amplifier with a combination of extremely low offset voltage and very low input bias currents. Unlike JFET amplifiers, the low bias and offset currents are relatively insensitive to ambient temperatures, even up to 125degree.

DS18B20 Digital Thermometer provides 9-12bit temperature readings which indicate the temperature of the device

The DS18B20 Digital Thermometer provide 9-12bit temperature readings which
indicate the temperature of the device.
Information is sent to or from the DS18B20 over a one-Wire interface, so that only one wire needs to be connected from a central microprocessor to a DS18B20. Power for reading, writing, and performing temperature conversions can be derived from the data line itself with no need for an external power source.
Because each DS18B20 contains a unique silicon serial number, multiple DS18B20s can exist on the same one-Wire bus. This allows for placing temperature sensors in many different places. Applications where this feature is useful include HVAC environmental controls, sensing temperatures inside buildings,equipment or machinery, and process monitoring and control.

STM32F103VC Mainstream Performance line, ARM Cortex-M3 MCU with 256 Kbytes Flash, motor control, USB and CAN

The STM32F103xC, STM32F103xD and STM32F103xE performance line family incorporates the high-performance ARM®Cortex®-M3 32-bit RISC core operating at a 72 MHz frequency, high-speed embedded memories (Flash memory up to 512 Kbytes and SRAM up to 64 Kbytes), and an extensive range of enhanced I/Os and peripherals connected to two APB buses. All devices offer three 12-bit ADCs, four general-purpose 16-bit timers plus two PWM timers, as well as standard and advanced communication interfaces: up to two I2Cs, three SPIs, two I2Ss, one SDIO, five USARTs, an USB and a CAN
