Frequently Asked Questions

How much program memory does the ATMEGA88PB-AU microcontroller provide?

The ATMEGA88PB-AU includes 8KB of flash program memory alongside 1KB of SRAM and 512B of EEPROM, giving designers enough on-chip storage for typical 8-bit control applications running at up to 20MHz.

Can the ATMEGA88PB-AU run at low supply voltages for battery designs?

Yes, the ATMEGA88PB-AU is rated to operate down to a 1.8V minimum supply voltage at 4MHz, which lets designers build battery-powered 8-bit control systems that conserve power while retaining 8KB flash.

Which embedded designs benefit most from the ATMEGA88PB-AU's 32-pin TQFP footprint?

Space-constrained embedded designs such as small appliance controllers and sensor nodes benefit most, since the 32-pin TQFP package pairs an 8-bit AVR core with 20MHz clock speed and 8KB flash in a compact surface-mount footprint.
