Microcontrollers

Microchip Technology's ATMEGA168-20MU is a low-power, high-performance 8-bit microcontroller unit (MCU) that belongs to the AVR Enhanced series. It is designed to provide a cost-effective solution for a wide range of applications, including industrial control, medical devices, and consumer electronics.

Description:

The ATMEGA168-20MU is a microcontroller based on the AVR architecture, featuring a high-speed 20 MHz clock frequency. It is housed in a 32-pin, 0.3-inch (8mm) wide, 4.9mm high, and 1.5mm pitch, QFN (Quad Flat No-leads) package. The package is designed for surface-mount technology (SMT) and offers a compact form factor suitable for space-constrained applications.

Features:

1. CPU: 8-bit AVR RISC-based microcontroller with a 20 MHz clock frequency.
2. Memory:
   • 16 KB of In-System Programmable (ISP) Flash memory for program storage.
   • 1 KB of EEPROM for non-volatile data storage.
   • 1 KB of SRAM for temporary data storage.
3. I/O: 14 digital I/O pins with support for various I/O modes, including PWM, ADC, and digital communication interfaces like SPI, TWI, and USART.
4. ADC: 8-channel, 10-bit Analog-to-Digital Converter (ADC) with a maximum conversion rate of 100 ksps (kilo samples per second).
5. Communication Interfaces: Serial Peripheral Interface (SPI), Two-Wire Interface (TWI), and Universal Synchronous/Asynchronous Receiver/Transmitter (USART).
6. Timers: 2 independent 8-bit Timer/Counters with PWM and Input Capture/Output Compare modes.
7. Interrupts: 15 interrupt sources, including external interrupts, timer interrupts, and I/O pin change interrupts.
8. Power Management: Sleep mode, Power Reduction Register (PRR), and Brown Out Detector (BOD) for energy-efficient operation.
9. Security: JTAG interface for debugging and programming, with an option to disable it for added security.
10. Operating Voltage: 1.8V to 5.5V.
11. Operating Temperature Range: -40°C to +85°C.

Applications:

1. Industrial control systems: Programmable logic controllers, motor control, and sensor interfacing.
2. Medical devices: Glucose meters, blood pressure monitors, and portable diagnostic equipment.
3. Consumer electronics: Home automation, portable gaming devices, and smart appliances.
4. Automotive applications: Instrumentation, infotainment systems, and body control modules.
5. Telecommunications: Modems, routers, and other network devices.
6. Energy management: Smart meters, energy monitoring systems, and lighting control.
7. Security systems: Access control, intrusion detection, and surveillance cameras.

The ATMEGA168-20MU is a versatile and efficient microcontroller suitable for a wide range of applications that require low power consumption, high performance, and a compact form factor.
