ATMEGA168PA-CCU Description

Short technical summary and product information.

The ATmega168PA-CCU is a low-power, 8-bit AVR microcontroller from Microchip Technology based on the enhanced RISC architecture. It achieves up to 20 MIPS throughput at 20 MHz maximum clock frequency.

 

Memory resources include 16KB of in-system self-programmable Flash, 1KB SRAM, and 512B EEPROM with high endurance (10,000 Flash/100,000 EEPROM write/erase cycles). Peripheral features include two 8-bit timers, one 16-bit timer, six PWM channels, an 8-channel 10-bit ADC, and serial interfaces (I2C, SPI, USART). The device also supports QTouch capacitive touch sensing.

 

Operating from 1.8V to 5.5V supply, it is suitable for battery-powered and low-voltage applications. The internal oscillator simplifies design. The operating temperature range is -40°C to 85°C.

 

Packaged in a 32-UFBGA (4x4 mm) surface-mount package, it is ideal for space-constrained designs. The microcontroller includes brown-out detection, power-on reset, and watchdog timer for reliable operation.
