ATMEGA164PA-AU Description

Short technical summary and product information.

The ATMEGA164PA-AU is an 8-bit AVR microcontroller from Microchip Technology based on the enhanced RISC architecture. It features 16KB of in-system self-programmable Flash memory with 10,000 write/erase cycles, 1KB SRAM, and 512B EEPROM with 100,000 cycles. The device operates at a maximum clock frequency of 20MHz, delivering up to 20MIPS throughput. It supports a supply voltage range of 1.8V to 5.5V and is rated for an operating temperature range of -40°C to 85°C.

 

Peripherals include brown-out detect/reset, power-on reset, PWM, and watchdog timer. The microcontroller integrates an 8-channel 10-bit analog-to-digital converter and provides 32 general-purpose I/O pins. Connectivity interfaces include I²C, SPI, and UART/USART. It also features an internal oscillator and supports JTAG boundary scan for debugging and programming.

 

The device is housed in a 44-TQFP (10x10mm) surface-mount package, suitable for compact PCB designs. Data retention is specified as 20 years at 85°C and 100 years at 25°C. The microcontroller supports QTouch capacitive touch sensing, making it applicable to human-machine interface applications.
