Frequently Asked Questions
What is the maximum operating frequency and supply voltage range for ATMEGA164PA-PU?
ATMEGA164PA-PU operates at up to 20 MHz from a 2.7 V to 5.5 V supply, or up to 4 MHz when the supply voltage is as low as 1.8 V, giving designers flexibility for both high-performance and battery-powered applications.
How many I/O pins and ADC channels does ATMEGA164PA-PU provide for sensor-rich designs?
The device offers 32 programmable I/O lines and an 8-channel 10-bit ADC, enabling connection to multiple analog sensors, digital peripherals, and communication buses simultaneously in a single DIP-40 package.
Does ATMEGA164PA-PU support JTAG debugging for production test and in-circuit validation?
Yes. ATMEGA164PA-PU includes a JTAG boundary scan interface that supports in-circuit debugging, programming, and production board testing, reducing development time and enabling full in-system validation without custom test fixtures.
When is ATMEGA164PA-PU preferred over surface-mount AVR variants for a new PCB design?
The DIP-40 through-hole package makes ATMEGA164PA-PU ideal for rapid prototyping on breadboards, socketed evaluation boards, and low-volume production where reworkability matters more than achieving the smallest possible PCB footprint.
