The ATTINY24A-MU from Microchip is a compact 8-bit AVR tinyAVR MCU with 2KB Flash, 128B SRAM, 12-channel 10-bit ADC, and picoPower in VQFN-20.

The ATTINY24A-MU is an 8-bit AVR microcontroller from Microchip in VQFN-20 (4x4mm), with 2KB Flash, 128B SRAM, and 128B EEPROM. The -A suffix denotes the picoPower revision with improved low-power modes. The AVR core uses a modified Harvard architecture with 16-bit instructions and single-cycle ALU operations (most instructions execute in 1 clock at 20MHz, giving 20 MIPS). The 10-bit ADC supports 8 input channels (PA0-PA7) with 65us conversion time at 200kHz sample rate. The ADC features a selectable 1.1V internal reference or external AREF pin voltage. The USI (Universal Serial Interface) provides hardware support for SPI and I2C master/slave modes with minimal CPU overhead (shift register + counter). The two 8-bit timers (Timer0 and Timer1) generate two PWM outputs each (OC0A, OC0B, OC1A, OC1B) for motor control and LED dimming. The picoPower technology achieves 300nA in power-down mode (everything stopped, watchdog off) and 340uA/MHz in active mode at 1.8V. The watchdog timer with independent oscillator can wake the MCU from power-down after a programmed interval. The internal calibrated RC oscillator runs at 8MHz (divisible to 1MHz), eliminating external crystal cost. The VQFN-20 package provides 12 I/O pins in a 4x4mm footprint, ideal for space-constrained sensor and control applications.
