ATTINY13A-PU 8-Bit picoPower AVR Microcontroller DIP-8 (ATTINY13A-PU IC)
The ATTINY13A-PU is a high-performance, low-power 8-bit AVR RISC-based microcontroller from Microchip (formerly Atmel). Housed in an 8-pin DIP package, it is a favorite for space-constrained projects due to its tiny footprint and high efficiency. Despite its small size, it features 1KB of ISP Flash, 64 bytes of EEPROM, and 64 bytes of SRAM. Its "picoPower" technology allows it to operate with extremely low power consumption, making it ideal for battery-operated handheld devices.
This IC is widely used in the Indian maker community for building simple automated controllers, LED blinkers, and sensor nodes. Its breadboard-friendly through-hole design and ability to run without an external crystal (using its calibrated internal oscillator) make it one of the most popular choices for entry-level AVR programming and compact hobbyist electronics.
Key Features
- picoPower Technology: Optimized for ultra-low power consumption in active and sleep modes.
- Advanced RISC Architecture: 120 powerful instructions, most executing in a single clock cycle.
- Internal Calibrated Oscillator: Eliminates the need for an external crystal for most applications.
- In-System Programmable: Flash memory can be updated via the SPI port without removing the chip.
- Self-Programming: Supports system-programmable Flash for flexible firmware updates.
- Peripheral Rich: Includes one 8-bit timer, two PWM channels, and a 4-channel 10-bit ADC.
- Wide Voltage Range: Operates reliably from 1.8V to 5.5V.
