ATTINY261A-SU ATTINY261A-SUR AVR Series Microcontroller Integrated Circuits IC

ATMEL 8-bit Microcontroller integrated circuits with 2/4/8K Bytes In-System Programmable Flash IC

The ATtiny261A/ATtiny461A/ATtiny861A of microchip provides the following features:

2/4/8K byte of In-System Programmable Flash, 128/256/512 bytes EEPROM, 128/256/512 bytes SRAM, 16 general purpose I/O lines, 32 general purpose working registers, an 8-bit Timer/Counter with compare modes, an 8- bit high speed Timer/Counter, a Universal Serial Interface, Internal and External Interrupts, an 11-channel, 10-bit ADC, a programmable Watchdog Timer with internal oscillator, and four software selectable power saving modes.

Idle mode stops the CPU while allowing the SRAM, Timer/Counter, ADC, Analog Comparator, and Interrupt system to continue functioning.

Powerdown mode saves the register contents, disabling all chip functions until the next Interrupt or Hardware Reset.

ADC Noise Reduction mode stops the CPU and all I/O modules except ADC, to minimize switching noise during ADC conversions. In Standby mode, the crystal/resonator oscillator is running while the rest of the device is sleeping, allowing very fast start-up combined with low power consumption.

The device is manufactured using Atmel’s high density non-volatile memory technology.

The On-chip ISP Flash allows the Program memory to be re-programmed In-System through an SPI serial interface, by a conventional non-volatile memory programmer or by an On-chip boot code running on the AVR core.

The ATtiny261A/461A/861A AVR is supported by a full suite of program and system development tools including: C Compilers, Macro Assemblers, Program Debugger/Simulators, and Evaluation kits.

Angel Technology Electronics Co Was Founded In HongKong Since 2006, Our branch Located In The Silicon Valley Of China, Shenzhen.Angel Technology provide one stop service for electronic components,PCB and PCB Assembly(SMT).

The Mission Of  Angel Technology Electronics Co has always been to provide Quality Electronics Components To Manufacturers Worldwide.Angel-tech's vision is become the excellent electronic components supplier with the highest satisfaction between employees and customers. Early On We became the Primary channel for project closures And Inventory build-ups for Major Distributors such as Arrow Electronics and Contract Manufacturers. Angel Technology Electronics Co Has since then added Sourcing Of High Quality Components From Local Manufacturers In China.

The corporate Philosophy Policy of  Angel Technology Electronics Co is Innovation,Not limited by the inhereent thinking,always looking for new ways to meet the needs of the market.So We have specialized in providing customers with one-stop service of electronic components, PCB and SMT since 2006, helping end customers to efficiently complete the full project including BOM list procurement process etc.

Angel Technology Electronics Co Has always been Customer Driven Rather than Opportunity Driven. Meaning- Angel Tech Will Always Choose Path That is the best For Long Term Relationship With Customer Over Short Term View. It Is Why We Have One Of The Highest Customer Retention Scores Of China Based Distributors.

Prioritizes client satisfaction:

Because of our clients are at the heart of how we work,At Angel Technology Electronic Co, our goal is to provide customers with electronic components supply,PCB production, SMT assembly one-stop service.

IInnovation and creativity:
We believe that innovation is fundamental to our success and we take particular pride in regularly working closely with industry innovators and our clients to set new standards. In recent years, Angel Technology Electronics co have also started collaborating with more and more corporations to explore new technologies in smart home and PMIC.

Inventory management:
Angel Technology Electronics co provides a third-party warehousing and professional IT inventory management software for customers to achieve seamless docking. The ownership of parts can only be transferred when the customer uses parts.

Angel Technology Electronic's incoming parts have undergone rigorous inspection, and the products are stored in standard anti-static, anti-humidity, anti-high temperature, and the stock are regularly tested to make the parts safe.

Packaging transportation standard :
The parts are tested for performance during shipment, and the packaging must be waterproof, moisture-proof and shock-proof. At the same time, Angel Technology Electronics cooperates with a number of international first-class freight companies to ensure that the parts of first- and second-tier cities can be delivered at that day, and arrive the next day.
