Microchip Technology's ATMEGA168-15MT Microcontroller

The ATMEGA168-15MT is a high-performance, low-power Atmel 8-bit AVR RISC-based microcontroller from Microchip Technology, combining 16KB ISP flash memory, 512-Byte EEPROM, 1KB SRAM, and a wealth of versatile peripherals. This microcontroller operates at a voltage range of 1.8-5.5 volts, making it suitable for a broad spectrum of applications, from consumer electronics to industrial control systems.

Featuring an advanced RISC architecture, the ATMEGA168-15MT offers efficient processing with a throughput approaching 1 MIPS per MHz, balancing power consumption and processing speed. The device is clocked at 15 MHz, providing ample speed for complex operations in embedded systems. Its high endurance, non-volatile memory segments are programmable in-system through an SPI serial interface, by a conventional non-volatile memory programmer, or by an on-chip boot program running on the AVR core.

The ATMEGA168-15MT boasts a comprehensive feature set, including:

• 23 general-purpose I/O lines
• 32 general-purpose working registers
• Three flexible Timer/Counters with compare modes
• Internal and external interrupts
• A serial programmable USART
• A byte-oriented Two-Wire Serial Interface
• A 10-bit ADC with 8 channels
• A programmable Watchdog Timer with internal oscillator
• Five software selectable power saving modes

The ADC feature offers a resolution of 10 bits and is capable of conversions in 13 to 260 microseconds. The device supports a variety of power-saving modes, which enable the design of low-power applications. These modes include Idle, ADC Noise Reduction, Power-save, Power-down, and Standby.

Designed with an emphasis on robustness and reliability, the ATMEGA168-15MT incorporates an on-chip analog comparator and a brown-out detection mechanism, ensuring stable operation under variable power conditions. The package is a 32-lead, thin quad flat pack (TQFP) form factor, ideal for space-constrained applications.

Microchip Technology's ATMEGA168-15MT microcontroller is a versatile and powerful component for designers looking to create efficient and feature-rich embedded systems. With its extensive set of peripherals, low power consumption, and large memory capacity, it is an excellent choice for a wide range of applications.
