The ATTINY44-20SSU is a low-power 8-bit CMOS Microcontroller based on the AVR enhanced RISC architecture. By executing powerful instructions in a single clock cycle, the ATtiny44 achieves throughputs approaching 1MIPS per MHz allowing the system designer to optimize power consumption versus processing speed. The AVR core combines a rich instruction set with 32 general purpose working registers. All 32 registers are directly connected to the arithmetic logic unit (ALU), allowing two independent registers to be accessed in one single instruction executed in one clock cycle. The resulting architecture is more code efficient while achieving throughputs up to ten times faster than conventional CISC microcontrollers. The ATtiny44 provides 4kB of in-system programmable flash, 256byte EEPROM and 256byte SRAM. The device supports a throughput of 20MIPS at 20MHz.

Great quality Cabin and air filter bundle pack. Very solid quality.
Size: 18-22 1.5L, Size: 18-22 1.5L
First off, I like that it's a combo pack instead of me having to buy each one individually and being able to change both at the same time. Now, I must say the quality of both of them is fantastic; I'm really impressed. It's not made out of cheap junk; it feels solid and seems like it will do a good job filtering out all the debris and dirt. It was extremely easy to install and fit perfectly like an OEM air filter and cabin air filter on my Honda Accord. The cabin air filter is definitely a solid piece, and you don't have to worry about it getting crushed or deforming as it's padded, I would assume the reason for the padding on the side of the cabin air filter is that no debris or dust sneaks through which gives it a snug fit which is very smart honestly. The same applies to the air filter that goes under the hood; it definitely feels like a quality piece.
A quality filter definitely keeps outside odors and smells from coming inside the cabin, allowing you to get fresh, clean air when you turn your AC on.
Overall, definitely a solid purchase, and I will definitely be back to buy this exact bundle pack in the future as it's well-built and fits like a glove. So, you're definitely getting great value for your money with this specific engine and cabin air filter combo pack.
There are a lot of garbage ones out there, so if it were flimsy and felt like a cheap filter, I would be giving this one or two stars. But I'm actually quite impressed with this company, and it seems to be doing a fine job. My AC does work better after installing these new filters, and of course, the car runs better with the air filter installed.
