Microchips – are indeed can be considered a black box – as long as it’s working you normally don’t look inside.
But what if you want to?
Today we’ll show how to “open” chips and what’s inside.

Microchip Technology Inc today announced from EE Live! and the Embedded Systems Conference in San Jose the PIC16(L)F170X and PIC16(L)F171X family of 8-bit microcontrollers (MCUs), which combine a rich set of intelligent analog and core independent peripherals, along with cost-effective pricing and eXtreme Low Power (XLP) technology. Available in 14-, 20-, 28-, and 40/44-pin packages, the 11-member PIC16F170X/171X family of MCUs integrates two Op Amps to drive analog control loops, sensor amplification and basic signal conditioning, while reducing system cost and board space. These new devices also offer built-in Zero Cross Detect (ZCD) to simplify TRIAC control and minimize the EMI caused by switching transients. Additionally, these are the first PIC16 MCUs with Peripheral Pin Select, a pin-mapping feature that gives designers the flexibility to designate the pinout of many peripheral functions. The PIC16F170X/171X are general-purpose MCUs that are ideal for a broad range of applications, such as consumer (home appliances, power tools, electric razors), portable medical (blood-pressure meters, blood-glucose meters, pedometers), LED lighting, battery charging, power supplies and motor control.

This instructable fully describes building a PWM driver to control four LEDs from one small Microchip 12F609 board. The original design was called the “Kemper LED Lamp” and I sold a few lamps to several brave folks through my web site. However, I’ve come to discover selling small quantities to a few folks is a major pain in the backside. Hand soldering these together and then selling them at $4 bucks each is no way to make money.

Microchip announces two new 8-bit PIC microcontrollers (MCUs), the PIC16F527 and PIC16F570, which combine a PIC MCU with a dual Op Amp module, an 8-bit ADC and two comparators. The new MCUs add several features to support ease of use and system robustness.

This tiny little breakout board has Microchip’s 24LC512 EEPROM and MCP9802 temperature sensor devices, both of which support I2C protocol. This board can be used for both sensing the ambient temperature and storing it. The MCP9802 is a digital temperature sensor with an user-selectable resolution from 9 to 12 bit. It can measure temperature ranging from -55°C to +125°C and notifies the host microcontroller when the ambient temperature exceeds a user programmed set point through its ALERT output pin. This board allows you to store up to 32000 temperature samples when you use the sensor in high resolution mode (12-bit, 0.0625°C) with each sample stored as two bytes. Raj (from embedded-lab.com) is selling this board for $9.00 on Tindie.

LDOs Provide Output Current of 300 mA, Input Voltage of 16V and Noise Rejection of 70 dB. Steve Taranovich writes:
Microchip Technology Inc., announced the MCP1755 and MCP1755S family of CMOS Low-Dropout (LDO) voltage regulators. These LDOs have an input voltage range of 3.6-16V and deliver an output current of 300 mA at output voltages of 1.8-5.5V, while consuming only 68 µA of quiescent current (typical). Additionally, the LDOs have a shutdown pin, enabling them to consume less than 0.1 µA (typical) during shutdown mode, which extends battery lifetimes. The LDOs are offered in SOT and 2×3 mm DFN packages.

The PIC24F is a very versatile piece of hardware. I use it at work all the time. Along with the MPLAB IDE and the free C30 compiler, these products from Microchip make for a powerful combination. You can pretty much do anything on the lower end of the frequency spectrum. I would like to share with the web, some of the intricacies of the microcontroller as I have become somewhat familiar with the chip. Most of these resources will apply to the other processors from Microchip 16-bit series. If you have any questions, feel free the comment or email. Come back to this page often as I will be adding features and code for all of the web to see.

This project is “NanoUtils Xtal” – a crystal oscillator breakout board. The board is designed to be interfaced with microcontrollers that have their oscillator pins next to a ground pin. [via]
This board is a breakout containing a SMD crystal, two caps and a resistor meant to be used in breadboards when building something with an Atmel ATmega or a Microchip PIC that have the two crystal pins next to a GND pin. For instance the atmega328 or pic18f2550.

The UBW board is a small board that contains a Microchip PIC USB-capable microcontroller, headers to bring out all of the PICs signal lines (to a breadboard for example), only costs about $15-$20 to build and is powered from the USB connection.
