ATMEGA164P-B15MZ

ATmega164P-B15MZ is a member of Microchip/Atmel’s AVR megaAVR 8-bit microcontroller family. It uses an AVR RISC core and is designed for embedded control tasks.
Key points:
- Core: 8-bit AVR, most instructions execute in one cycle; up to ~16 MIPS at full speed.
- Memory: includes on-chip program flash, RAM, and EEPROM (exact sizes vary by variant).
- Peripherals: timers (Timer0/1/2), USART, SPI, I2C (Two-Wire), ADC with multiple channels, PWM outputs, and multiple I/O ports.
- Voltage and speed: typically operates from a range around 1.8–5.5 V; clock up to 16 MHz (depending on package/grade).
- Package/availability: the -B15MZ suffix refers to the specific package/temperature grade (commonly a 44-pin variant in the ATmega164P line); check the datasheet for exact packaging.
- Common uses: general embedded control, motor control, sensing, data acquisition, and similar applications.
For exact specifications (memory sizes, pinout, and packaging), consult the ATmega164P datasheet or product page.
