ATTINY88-AUR

The ATTINY88-AUR is an 8-bit AVR microcontroller from Microchip Technology based on the high-performance, low-power AVR RISC architecture. It features 8KB of in-system self-programmable Flash memory, 512B of SRAM, and 64B of EEPROM with high endurance (10,000 write/erase cycles for Flash, 100,000 for EEPROM) and data retention of 20 years at 85°C or 100 years at 25°C.

The device includes a rich set of peripherals: one 8-bit and one 16-bit timer/counter, an 8-channel 10-bit ADC, Master/Slave SPI and I2C serial interfaces, a programmable watchdog timer, an on-chip analog comparator, and a temperature sensor. It also supports debugWIRE for on-chip debugging and in-system programming via SPI.

Operating from 1.8V to 5.5V, the ATTINY88-AUR offers multiple speed grades: up to 4 MHz at 1.8V, 8 MHz at 2.7V, and 12 MHz at 4.5V. Power consumption is optimized for battery-powered applications, with 240 µA typical active current at 1 MHz/1.8V and 0.1 µA in power-down mode. The microcontroller is housed in a 32-lead TQFP package (7x7mm) for surface mount assembly and operates over an industrial temperature range of -40°C to +85°C.
