Microchip partnered with Kalki Technologies to provide a Device Language Message Specification (DLMS) protocol stack that is optimized for 16-bit PIC® microcontrollers (MCUs). The DLMS protocol has become the worldwide standard of choice among smart meter designers for interoperability among metering systems, including most energy types (electricity, gas, heat and water), multiple applications (residential, transmission and distribution), and numerous communication media (RS232, RS485, PSTN, GSM, GPRS, IPv4, PPP and PLC); as well as secure data access, via AES 128 encryption.

The HP 95LX is reputedly the smallest MS-DOS computer ever built, and it runs off a pair of AA batteries. Here, I have it connected up to a MAX232 level shifter and an Atmel AVR chip, the ATmega8, at 9600 baud.
MCUs offering extensive connectivity interfaces, powerful performance and robust hardware-based security.
Detail of a single chip calculator IC from 1971, arguably one of the first microprocessors or microcontrollers having a RISC instruction set in ROM and with RAM. This complex IC was drawn out by hand on Mylar film and photo-reduced 400X. Calculators became the largest market for ICs by the mid 1970s.

To enable development with the LAN9353/4/5 Three-Port 10/100 Ethernet Switches, three Microchip evaluation boards were also added that support various system architectures. These hardware systems demonstrate how to interface with the switches through basic input/output connections, or with microcontrollers such as the 32-bit PIC32MX family via serial communications.
Each of these new evaluation boards is also supported by a Software Development Kit (SDK), which enables developers to immediately start device evaluation, familiarize themselves with features, and begin building solutions for their applications. All three evaluation boards, (part # EVB-LAN9353, $300), (part # EVB-LAN9354, $250) and (part # EVB-LAN9355 $300) are available now via any Microchip sales representative or authorized worldwide distributor, or from microchipDIRECT (www.microchipdirect.com).

The PIC16F75X family of 8-bit microcontrollers (MCUs) featuring intelligent analog and core-independent peripherals, making them ideal for general-purpose applications, as well as power supplies, battery charging, LED lighting, power management and power control/smart energy applications. The new PIC16F753 MCU builds on the success of the popular PIC12F752. The PIC16F753 offers all the key features of the PIC12F752, such as the integrated Complementary Output Generator (COG) peripheral that provides non-overlapping, complementary waveforms for inputs such as comparators and Pulse Width Modulation (PWM) peripherals, while enabling dead-band control, auto shutdown, auto reset, phase control and blanking control. Additionally, the PIC16F753 offers an Op Amp with 3 MHz of Gain Bandwidth Product (GBWP), and a slope compensation circuit to help in Switch Mode Power Supply applications.

I have been building projects using PIC microcontrollers for years. This is one of my best devices. This is used during a speech in a Toastmasters club to inform the speaker of their time remaining. Green LEDs indicate they have spoken long enough, red means time is up, and yellow is halfway in-between. All of the LEDs are colored, even though some appear clear in the photo. The control panel and LCD display offer great flexibility in how the timer operates.
