Product Overview
The ATmega328P is a low-power, high-performance 8-bit AVR RISC-based microcontroller combining 32KB ISP Flash memory, 1024B EEPROM, 2KB SRAM, 23 general purpose I/O lines, 32 general purpose working registers, three flexible timer/counters, and a full duplex serial USART. This is the chip used in the Arduino Uno. Key Features: - 8-bit AVR CPU @ up to 20 MHz - 32KB self-programming Flash, 1KB EEPROM, 2KB SRAM - 23 programmable I/O lines - 6-channel, 10-bit ADC - Two 8-bit and one 16-bit timer/counter - USART, SPI, TWI (I2C) interfaces - 1.8V to 5.5V operating voltage - TQFP-32 SMD package
Procurement Notes
Use this page as a sourcing reference. Final availability, MOQ, lead time, and compliance assumptions should be confirmed through RFQ before ordering this part.
Substitute Selection Notes
When the original MPN is constrained, compare package, ratings, tolerance, temperature range, and compliance status before approving an alternate.
Typical Use Cases
Suitable for BOM review, maintenance sourcing, prototype replenishment, production-gap purchasing, and alternative-part screening.
