ATMEGA328P-15MZ

The ATMEGA328P-15MZ is a high-performance, low-power 8-bit AVR microcontroller from Microchip Technology designed for automotive and embedded applications. It features an advanced RISC architecture with 131 instructions, most executing in a single clock cycle, enabling throughput up to 20 MIPS at 20MHz (maximum speed of the core family, though this specific device is rated for 16MHz).

The device offers 32KB of in-system self-programmable Flash program memory, 2KB of SRAM, and 1KB of EEPROM with high endurance (10,000 Flash write/erase cycles, 100,000 EEPROM cycles). On-chip peripherals include two 8-bit timers, one 16-bit timer, six PWM channels, an 8-channel 10-bit ADC, and a programmable USART, master/slave SPI, and byte-oriented 2-wire serial interface (I²C). It also includes a brown-out detect/reset, power-on reset, and watchdog timer.

The microcontroller operates over a wide voltage range of 2.7V to 5.5V and a temperature range of -40°C to +125°C, making it suitable for harsh environments. It is available in a compact 32-VFQFN exposed pad package (5x5mm) with 23 I/O pins and surface-mount tape-and-reel packaging for automated assembly. An internal oscillator reduces external component count.
