The MCP9600 Thermocouple interface


by Martin Cooke @ elektormagazine.com:

The MCP9600 from Microchip is a single chip solution to convert thermocouple output EMF to degrees Celsius. The chip includes integrated cold-junction compensation and corrects thermocouple non-linearity for the eight most popular types of thermocouple.

User-programmable registers in the MCP9600 allow the chip to be configured for various applications including a low-power mode for battery operation and adjustable digital filter characteristics for fast-changing transient temperature sensing. There are also four programmable temperature alert outputs which can be used to detect multiple temperature zones.

TC7106 – 3 1/2 Digit ADC for LCD Display


The TC7106 3½ digit LCD direct-display drive analog-to-digital converter has a reference with a 80ppm/°C max temperature coefficient. TC7106 based systems may be upgraded without changing external passive component values to the TC7106A for a more precise system. High impedance differential inputs offer 1pA leakage current and a 1012 Ohm input impedance. The differential reference input allows ratiometric measurements for ohms or bridge transducer measurements. The 15µVp-p noise performance guarantees a great reading. The auto-zero cycle guarantees a zero display reading with a zero-volts input.

Delay using 8051 Timer

The major component of this circuit is Microchip’s SST89E54RDA-40-C-PIE, which is a pin-for-pin compatible with typical 8051 microcontroller devices. It has a built-in timer used to produce accurate time delay. The light emitting diode (LED) is connected through the 330Ω resistor to indicate the time delay. The blinking LED switches ON for 1ms and switches OFF for 1ms that indicates toggling from LOW to HIGH and HIGH to LOW. Output PIN P2.2 can be connected to an oscilloscope to generate a square wave.

SST89E58RDA-40-C-PIE comes with 72 Kbyte of on-chip flash EEPROM program memory that is partitioned into 2 independent program memory blocks. The primary Block 0 occupies 64 Kbyte of internal program memory space and the secondary Block 1 occupies 8 Kbyte of internal program memory space. The 8-Kbyte secondary blocks can be mapped to the lowest location of the 64 Kbyte address space; it can also be hidden from the program counter and used as an independent EEPROM-like data memory. In addition to the 72 Kbyte of EEPROM program memory on-chip and 1024 x8 bits of on-chip RAM, the devices can address up to 64 Kbyte of external program memory and up to 64 Kbyte of external RAM.

This design integrating Microchip’s SST89E54RDA-40-C-PIE would be used if high-accuracy, precision and timing resolution of timed events are required to activate or deactivate control outputs based on programmed time intervals. Time delay applications include pump control, food processing, and packaging control where precise ON/OFF control is necessary.

2 New Families from Microchip


by elektormagazine.com:

Microchip has introduced two new 8-bit MCU families with integrated Core Independent Peripherals (CIPs). You may be thinking that 8-bit processors are unlikely to cut the mustard for many of today’s applications but built-in interconnected CIPs combine to perform functions autonomously, without intervention from the processor. This makes these new 8-bit families suitable for a much broader range of applications. Functions are deterministically and reliably performed in hardware instead of software so the system performance is much better than you could otherwise expect from a typical 8-bit MCU. 8-bit architecture also leads to a simpler system design and reduced memory costs.

Microchip Touch and Gesture Solutions


by Martin Cooke @ elektormagazine.com:

Microchip has announced a new addition to its portfolio of human interface solutions. The MTCH6303 supports touch panel sensors with up to 1000 nodes and 10 inch diagonals. The device uses signal processing to filter noise and provide predictive tracking of up to 10 fingers, at scan rates of up to 250Hz with a minimum of 100Hz each for five touches. The projected-capacitive touch controller provides multi-touch coordinates as well as a ready-made multi-finger surface gesture suite that can bring modern user interface elements such as pinch and zoom, multifinger scrolling and swipes to any embedded design with minimal loading on the host processor. It can also be used with Microchip’s MTCH652 high-voltage line driver to achieve better SNR in noisy environments.

When combined with the MGC3130, the MTCH6303 solution is also capable of supporting 3D air gestures up to 20cm distance from the touch panel. Microchip’s MGC3130 E-field-based 3D tracking and gesture controller includes Microchip’s patented GestIC technology, allowing user input via natural hand and finger movements in free space.

Waffle implant supplies drugs


by Rob Matheson @ MIT News Office:

An implantable, microchip-based device may soon replace the injections and pills now needed to treat chronic diseases: Earlier this month, MIT spinout Microchips Biotech partnered with a pharmaceutical giant to commercialize its wirelessly controlled, implantable, microchip-based devices that store and release drugs inside the body over many years.

Invented by Microchips Biotech co-founders Michael Cima, the David H. Koch Professor of Engineering, and Robert Langer, the David H. Koch Institute Professor, the microchips consist of hundreds of pinhead-sized reservoirs, each capped with a metal membrane, that store tiny doses of therapeutics or chemicals. An electric current delivered by the device removes the membrane, releasing a single dose. The device can be programmed wirelessly to release individual doses for up to 16 years to treat, for example, diabetes, cancer, multiple sclerosis, and osteoporosis.

Microchip LoRa Network Module


Microchip Technology Inc., has announced the first in a series of modules for the LoRa technology low-data-rate wireless networking standard. The system is designed to allow Internet of Things (IoT) and Machine-to-Machine (M2M) wireless communication offering a range of more than 10 miles (suburban), a battery life of greater than 10 years, and the ability to connect millions of wireless sensor nodes to LoRa technology gateways. The 433/868 MHz RN2483 is a European R&TTE Directive Assessed Radio Module measuring 17.8 x 26.3 x 3 mm and with 14 GPIOs to provide connections and control for a large number of sensors and actuators.

The RN2483 is also supplied with the LoRaWAN™ protocol stack, allowing connection with the LoRa Alliance infrastructure—including both privately managed local area networks (LANs) and telecom-operated public networks—to create Low Power Wide Area Networks (LPWANs) with nationwide coverage. This stack integration also enables the module to be used with any microcontroller with a UART interface. The RN2483 also uses Microchip’s simple ASCII command interface for easy configuration and control.
