ATTINY24-20PU

The ATTINY24-20PU is an 8-bit AVR microcontroller from Microchip Technology, featuring a high-performance RISC architecture. It offers 2KB of in-system programmable Flash program memory, 128 bytes of SRAM, and 128 bytes of EEPROM with high endurance (10,000 write/erase cycles for Flash, 100,000 for EEPROM). Operating at a maximum speed of 20MHz, it provides 120 powerful instructions, most executed in a single clock cycle.

The device includes a rich set of peripherals: one 8-bit and one 16-bit timer/counter with two PWM channels each, a 10-bit ADC with 8 single-ended channels and 12 differential channel pairs with programmable gain, a programmable watchdog timer with separate on-chip oscillator, an on-chip analog comparator, and a universal serial interface (USI). It also features debugWIRE on-chip debug system, brown-out detection, power-on reset, and an internal calibrated oscillator.

Designed for low-power operation, the ATTINY24-20PU consumes 300 µA in active mode at 1MHz and 0.1 µA in power-down mode, making it suitable for battery-powered and energy-sensitive applications. It operates over a supply voltage range of 2.7V to 5.5V and supports an industrial temperature range of -40°C to +85°C.

The microcontroller is housed in a 14-pin PDIP (plastic dual in-line package) with a 0.300-inch (7.62mm) body width, suitable for through-hole mounting. It provides 12 programmable I/O lines and supports multiple interrupt sources including pin change interrupts on all 12 pins.
