ATTINY88 in ATtiny Family
The ATTINY88 is a high-performance, low-power Microchip 8-bit AVR RISC-based microcontroller designed for space-constrained applications. It bridges the gap between smaller ATtiny chips and larger ATmega parts by offering 8KB of Flash memory and up to 28 I/O lines. Known for its efficiency, it executes powerful instructions in a single clock cycle, achieving throughputs approaching 1 MIPS per MHz. It is widely utilized in industrial and consumer electronics where cost and power efficiency are paramount.

The ATTINY88 sub-family variants are primarily distinguished by their physical packaging and temperature ratings. The -AU suffix denotes a 32-lead TQFP package for surface-mount designs, while -MU identifies the space-saving 32-pad VQFN. For prototyping or through-hole manufacturing, the -PU variant provides a 28-pin PDIP format. All variants maintain core silicon parity, though different packages may expose different numbers of usable ADC channels and I/O pins.
