ATMEGA168PA-AN Description

Short technical summary and product information.

The ATMEGA168PA-AN is an 8-bit AVR microcontroller from Microchip Technology based on the advanced RISC architecture. It executes 131 powerful instructions, most in a single clock cycle, achieving up to 20 MIPS throughput at 20MHz. The core includes 32 general-purpose working registers and an on-chip 2-cycle multiplier.

 

Memory includes 16KB of in-system self-programmable Flash, 1KB SRAM, and 512B EEPROM with high endurance: 10,000 write/erase cycles for Flash and 100,000 for EEPROM, with data retention of 20 years at 85°C. Peripheral features include two 8-bit and one 16-bit timer/counter, six PWM channels, an 8-channel 10-bit ADC, and serial interfaces I2C, SPI, and USART.

 

The device operates from 1.8V to 5.5V and features multiple sleep modes (Idle, Power-down, Power-save, etc.) for low-power applications. Active current is 0.2mA at 1MHz/1.8V, and power-down current is 0.1µA. It is available in a 32-TQFP surface mount package (7x7mm) and is specified for an operating temperature range of -40°C to 85°C.
