The computer accessory solution based on Atmel megaAVR® microcontroller

Published time : 2018-01-02 Atmel microcontroller
The low-power management and high-efficiency RF capabilities built into the Atmel® AVR® solution make it the perfect application for battery-powered wireless remote control products.

Solution Introduction

The Features and advantages of solution

Atmel's single-chip battery management microcontrollers precisely control the voltage to extend the battery life of the peripherals, and use the chip to minimize the number of electronic components.

Atmel's single-chip battery-managed microcontrollers consume very little power in sleep mode and operate multiple functions at the lowest power consumption in active mode.

The Atmel megaAVR® microcontrollers feature self-programming flash memory for fast, secure, cost-effective, field upgrades and emergency programming. 

The single-chip solution uses capacitive touch to reduce cost.


Atmel microcontrollers and embedded MPUs combine system control, wired and wireless connectivity, and user interface management.

To meet the needs of the global market, our high-efficiency RF modules and software packages support the 700/800/900MHz and 2.4GHz bands.

Pre-tested and certified modules speed up prototyping and time to market.

Industry-standard connectivity support includes USB On-The-Go (OTG) wired interfaces, as well as WiFi, Bluetooth and ZigBee IEE 802 15.4 wireless interfaces.

The Atmel CryptoAuthenticationTM product is the best low-cost security solution for verifying all computer accessories and peripherals.


The wireless remote control device controls all settings from volume to device operation and temperature. Atmel offers responsive, reliable, and reliable integrated wireless connectivity.

USB hardware protection devices require connectivity, high computing performance, and fast interfaces. Atmel microcontrollers and embedded MPUs combine system control, wired and wireless connectivity, and user interface management.

The pointing device is ideal for Atmel QTouch® capacitive touch controllers. Signal processing in decision logic provides accurate and reliable button, slider or pulley touch operations. The key competitiveness is reflected in low power consumption.

With the Atmel solution, you can create a complete wireless environment with a capacitive touch remote control that can be based on a single-chip Atmel AVR microcontroller or one that is equipped with an IEEE 802.15.4 compliant Atmel low power Atmel microcontroller for external transceivers.

The Atmel remote control solution helps you enhance your RF network with a highly optimized bill of materials.

Some Descriptions about Atmel electronic parts 

The Atmel® AT24CSW01 and AT24CSW02

The Atmel® AT24CSW01 and AT24CSW02 Device Family Series provides 1,024 / 2,048 bits of Serial Electrically Erasable and Programmable Read-Only Memory (EEPROM) organized as 128 / 256 words of 8 bits each. 

The device is optimized for use in many industrial and commercial applications where low-power and low-voltage operation are essential.

The device features a Software Write Protection feature with five different programmable levels of protection for the EEPROM array. 

The protection settings of the device can made permanent if desired. Safeguards are included to prevent accidental invocation of the permanent feature.

Additionally, each device includes a Security Register with an extra 256 bits of EEPROM beyond the nominal EEPROM array. 

The Security Register is comprised of a read-only section of 16 bytes and an additional user-programmable section of 16 bytes.


ATBTLC1000-MR110CA

The ATBTLC1000-MR110CA is an ultra-low power Bluetooth® SMART (BLE 4.1) module with Integrated Transceiver, Modem, MAC, PA, TR Switch, and Power Management Unit (PMU). 

It can be used as a Bluetooth Low Energy link controller or data pump with external host MCU.

The qualified Bluetooth® Smart protocol stack is stored in dedicated ROM, the firmware includes L2CAP service layer protocols, Security Manager, Attribute protocol (ATT), Generic Attribute Profile (GATT), and the Generic Access Profile (GAP). 

Additionally, application profiles such as Proximity, Thermometer, Heart Rate, Blood Pressure and many others are supported and included in the protocol stack.

The module contains all circuitry required including a ceramic high gain antenna, 26MHz crystal, and PMU circuitry. The customer simply needs to place the module on his board and provide power and a 32kHz Real Time Clock or crystal. 

ATmega324PB

The picoPower® ATmega324PB is a low-power CMOS 8-bit microcontroller based on the AVR® enhanced RISC architecture. 

By executing powerful instructions in a single clock cycle, the ATmega324PB achieves throughputs close to 1MIPS per MHz. 

This empowers system designers to optimize the device for power consumption versus processing speed.
