ATMEGA8A-PN  

Microcontrollers

The ATMEGA8A-PN is a low-power, high-performance microcontroller unit (MCU) manufactured by Microchip Technology. It is based on the AVR enhanced low-power 8-bit RISC architecture and is designed for a wide range of embedded applications.

Description:

The ATMEGA8A-PN is an 8-pin package version of the popular ATMEGA8A MCU. It features 8 KB of in-system programmable flash memory, 1 KB of EEPROM, and 1 KB of SRAM. The device operates at a frequency of up to 20 MHz and has a wide operating voltage range of 1.8 - 5.5 V.

Features:

1. 8 KB In-System Programmable Flash (ISP) with read-while-write capability
2. 1 KB EEPROM
3. 1 KB SRAM
4. 8 MHz to 20 MHz operation frequency
5. 8-bit RISC architecture with 65 instructions and 32 general-purpose working registers
6. 16-bit Timer/Counter with PWM channel, 8-bit Timer/Counter, and watchdog timer
7. UART, SPI, and I2C serial communication interfaces
8. 8 MHz to 20 MHz crystal oscillator
9. Internal and external interrupts
10. ADC with up to 8 channels
11. Programmable watchdog timer
12. Sleep, power-down, and power-save modes for low-power consumption
13. Brown-out detection and reset
14. 8-pin PDIP (Plastic Dual In-line Package) package

Applications:

The ATMEGA8A-PN is suitable for a wide range of applications due to its low-power consumption, versatility, and ease of use. Some common applications include:

1. Industrial control and automation
2. Home automation and smart home devices
3. Battery-powered devices and portable electronics
4. Data acquisition and signal processing systems
5. Medical equipment and monitoring systems
6. Remote monitoring and control systems
7. Security systems and access control
8. In-vehicle control systems and telematics
9. Consumer electronics and appliances
10. Toys and games

The ATMEGA8A-PN's small form factor and low-power capabilities make it an ideal choice for applications where space and power consumption are critical factors.
