ATMEGA168PA-PU

The ATMEGA168PA-PU is a high-performance, low-power 8-bit AVR microcontroller from Microchip Technology. It features 16KB of in-system self-programmable Flash memory, 1KB of SRAM, and 512B of EEPROM with high endurance (10,000 write/erase cycles for Flash and 100,000 for EEPROM). The device operates at a maximum clock frequency of 20MHz, delivering up to 20 MIPS throughput.

This microcontroller includes a rich set of peripherals: two 8-bit timers, one 16-bit timer, six PWM channels, a 6-channel 10-bit ADC, and serial interfaces including I²C, SPI, and UART/USART. It also features an on-chip analog comparator, programmable watchdog timer, brown-out detection, and power-on reset. Six sleep modes (Idle, ADC Noise Reduction, Power-save, Power-down, Standby, and Extended Standby) enable efficient power management.

The device is housed in a 28-pin PDIP (0.300", 7.62mm) package and supports through-hole mounting. It operates over a supply voltage range of 1.8V to 5.5V and a temperature range of -40°C to +85°C, making it suitable for a wide variety of embedded control applications.
