Microchip ATMEGA88-20MU, 8bit AVR Microcontroller, Microcontrollers, 20MHz, 8 kB Flash, 32-Pin VQFN

The Microchip ATmega88 CMOS 8-bit microcontroller is based on the AVR enhanced RISC architecture. It operates on 2.7V to 5.5V voltage range. It features 8 KB ISP Flash memory with read-while-write capabilities, 512B EEPROM, 1 KB SRAM, 23 general purpose I/O lines, 32 general purpose working registers, three flexible timer/counters with compare modes, internal and external interrupts, serial programmable USART, a byte-oriented Two-Wire serial interface, SPI serial port, 6-channel 10-bit A/D converter (8-channels in TQFP and QFN/MLF packages), programmable watchdog timer with internal oscillator, and five software selectable power saving modes.Up to 20 MIPS throughput at 20MHz On-chip 2-cycle multiplier In-system programming by on-chip boot program Programming lock for software security Two 8-bit timer/counters with separate prescaler and compare mode One 16-bit timer/counter with separate prescaler, compare mode, and capture mode Master/slave SPI serial interface Byte-oriented 2-wire serial interface Programmable watchdog timer with separate on-chip oscillator On-chip analog comparator Interrupt and wake-up on pin change DebugWIRE on-chip debug system Power-on reset and programmable brown-out detection Internal calibrated oscillator External and internal interrupt sources 32-pad QFN/MLF package
