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.

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.

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.

40 & 28 PIN PIC Development Board

PIC004

The PIC 40 / 28 PIN (DIP) Development / Evaluations board demonstrates the capabilities of Microchip’s 8-bit microcontrollers, specifically, 28- and 40-pin PIC16FXXX, PIC16F1XXX, and PIC18 devices. It can be used as a standalone demonstration board with a programmed part. With this board you can develop and prototype with all Microchip’s 40 & 28 PIN PIC microcontrollers which doesn’t require crystals (External Oscillator). On board connector for UART (RX-TX) allows an easy connection with embedded hardware. The board has a Reset switch and status LEDs.

Microchip LoRa Network Module

microchipRN2483

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.

Microchip Introduces New 5V dsPIC33 “EV” Family for Enhanced Noise Immunity and Robustness in Harsh Environments

15843781961_7a919ec82f_z

Microchip Technology Inc. announced from the SPS IPC Drives Conference in Germany a new family of 16-bit dsPIC33 Digital Signal Controllers (DSCs) with the dsPIC33 “EV” family. This new family provides 5V operation for improved noise immunity and robustness, ideal for devices operating in harsh environments such as appliance and automotive applications. The dsPIC33EV family is the first dsPIC DSC with Error Correcting Code (ECC) Flash for increased reliability and safety. For safety-critical applications, the dsPIC33EV devices also include CRC, Deadman Timer (DMT), and Windowed Watchdog Timer (WWDT) peripherals as well as a backup system oscillator and certified Class B software.

Original PICKIT-2 microcontroller programmer

These days I was thinking about a better PIC programmer that can work with Microchip MPLAB IDE software so that I can write my own programs or edit someone else’s programs. I found that there are numerous versions of the famous Microchip PICkit 2 on the web.

Some of them are using the original schematic published by Microchip and some are lite versions – with different parts or simplified schematics. None of them satisfied my requirements. So I got the original schematic, removed the memory chips and the input ICSP connector (which I didn’t plan to use anyway) and made a new single sided PCB. I used mostly SMD parts.
