ATTINY24-20MU

The Atmel ATtiny24-20MU is a high-performance, low-power 8-bit AVR microcontroller based on an advanced RISC architecture. It executes 120 powerful instructions, most in a single clock cycle, and features 32 x 8 general-purpose working registers. The device integrates 2KB of in-system programmable Flash memory with 10,000 write/erase cycles endurance, 128B of SRAM, and 128B of EEPROM with 100,000 write/erase cycles. Data retention is rated at 20 years at 85°C and 100 years at 25°C.

Peripheral features include one 8-bit and one 16-bit timer/counter with two PWM channels each, a 10-bit ADC with 8 single-ended and 12 differential input pairs (with programmable gain), a programmable watchdog timer, an on-chip analog comparator, and a universal serial interface (USI). The microcontroller also supports debugWIRE on-chip debugging and in-system programming via SPI.

The ATtiny24-20MU operates over a supply voltage range of 2.7V to 5.5V, with a maximum clock speed of 20 MHz at 4.5V-5.5V and 10 MHz at 2.7V-5.5V. It is specified for the industrial temperature range of -40°C to +85°C. The device is available in a 20-lead QFN package with an exposed pad (4x4 mm) for surface-mount assembly.
