Microchip today announced a new series of its low-cost, high pin count 32-bit PIC32 microcontrollers (MCUs). By blending the key features of Microchip’s existing PICM32MX1/2 and PIC32MX5 MCU families, this latest PIC32MX1/2/5 MCU series delivers designers the benefits of a rich peripheral set for a wide range of cost-sensitive applications that require complex code and higher feature integration at a lower cost. With up to 83 DMIPS performance and large, scalable memory options from 512/64 KB Flash/RAM to 64/8 KB Flash/RAM, these new PIC32MX1/2/5 MCUs are ideal for executing the Bluetooth® audio software required for low-cost Bluetooth audio applications, such as speakers, consumer music-player docks, noise-cancelling headsets and clock radios. Flexible, easy-to-use CAN2.0B controllers are also integrated into these MCUs, with DeviceNet™ addressing support and programmable bit rates up to 1 Mbps, along with system RAM for storing up to 1024 messages in 32 buffers. This feature allows designers to easily employ CAN communication schemes for industrial and automotive applications. For more info, visit www.microchip.com/PIC32MX-Page-110314a

Programming Your Serialized LCD Display
This month we’re going to turn our attention to some of the details of programming the display. Specifically, we’ll investigate two of the most useful features of LCD displays: scrolling a long line of text across the relatively small width of the display and creating custom characters to enhance the functionality of the display.

Phrases such as “going green” and “carbon footprint” have become ubiquitous and even trendy. The United States Green Building Counsel (USGBC) has even developed a green building rating system called LEED by which new buildings are designed to be as energy efficient as possible. Those with the knowledge to innovate technologies for renewable resources might soon find themselves highly sought after!

How To Achieve One Gigabit Per Second Data Rate Over Wireless
Longer distances, interference, and other environmental issues usually prevent that, but what we get is typically enough. With the new 802.11n standard, Wi-Fi speeds will be going up as more of the access points adopt the multiple input multiple output (MIMO) technology that will make 100+ Mbps common.
Developing Perspectives
by Bryan Bergeron
I got this board because I needed a development platform for one of my microcontrollers. At the same time, I ordered an Atmel AVR ISP MkII programmer, which I wanted to use because it is a native USB device and is a little easier to use on the Mac. Of course, it turns out that the programmer has a different type of ISP connector than this board was expecting.
So, this is a Olimex development board for Atmel AVR 20-pin microcontrollers, modified it to accept input from the AVR ISP MkII, which has a six-pin output connector. The header that I added is at the bottom of the board.

Microchip announced an expansion of its eXtreme Low Power (XLP) PIC® microcontrollers (MCUs) with the PIC24F “GB2” family. This new family features an integrated hardware crypto engine, a Random Number Generator (RNG) and One-Time-Programmable (OTP) key storage for protecting data in embedded applications. The PIC24F “GB2” devices offer up to 128 KB Flash and 8 KB RAM in small 28- or 44-pin packages, for battery-operated or portable applications such as “Internet of Things” (IoT) sensor nodes, access control systems and door locks.

Sometimes we need to extend or add more I/O ports to our microcontroller based project; the question is how fast the response we need for these new I/O ports. Because usually we only have a limited I/O port left than the logical choice is to use the serial data transfer method; which usually only required maximum one to four ports for doing the data transfer.
Currently there is few type of modern embedded system serial data transfer interface widely supported by most of the chip’s manufactures such as I2C (read as I square C), SPI (Serial Peripheral Interface), 1-Wire (One Wire), Controller Area Network (CAN), USB (Universal Serial Bus) and the RS-232 families (RS-423, RS-422 and RS-485).
MCUs offering extensive connectivity interfaces, powerful performance and robust hardware-based security.
The short M3 nylon spacers are 8.25mm long over the hexagonal part, and the long ones are 12.5mm. A better length, for this purpose, would be 10mm.

The Motorola smart card sample is from the very early 90s or the late 80s. Motorola became very successful in the early days of smart cards providing 8 bit microcontrollers to companies such as Gemplus and Schlumberger. The smart card was first developed in France. The first GSM mobile phones had compete credit card sized smart cards inserted, before it made sense to provide a smaller SIM card.
The Hughes ID proximity card was developed in the 90s. Hughes were an early leader in the RFID market. The format is pretty much unchanged today. Inside the card is a coil (antenna), chip capacitor and an RFID chip.

This is a re-shoot of an old chip I opened up previously. I knew at the time that I could only see the metal layers and I needed a metallurgical scope to see anything else, so here we are.
Thanks to the improved camera and scope I can make out smaller details. According to the datasheet this chip has 128 Bytes of onboard SRAM and there are 32 rows and 32 columns in the mid-right block which equates to 1024 bits or 128 Bytes. Because of this I am fairly confident that block is the SRAM and the other two are the ROM.
This was pulled from an old opto-mechanical mouse which used a serial RS-232 connector. The top of the mouse and the ball were missing, so I was unable to identify the model. I think it is made by Logitech since the package has that written on it.
It was designed in 1988 and it uses HCMOS and It was based off of the Motorola 6800.

Microchip announced a new series within its high-performance PIC32MZ family of 32-bit microcontrollers (MCUs) that features an integrated hardware floating point unit (FPU) for high performance and lower latency in intensive single and double-precision math applications. This new 48-member PIC32MZ EF series also offers a 12-bit, 18 MSPS analog-to-digital converter (ADC) for a wide array of high-speed, wide-bandwidth applications. Additionally, the PIC32MZ EF supports an extensive DSP instruction set. This combination of DSP instructions, a double-precision FPU and a high-speed ADC improves code density, decreases latency and accelerates performance in process-intensive applications.
