Microchip Technology ATMEGA325PV-10MU

The ATMEGA325PV-10MU from Microchip Technology is a high-performance, low-power AVR® 8-bit microcontroller that combines 32KB ISP flash memory with read-while-write capabilities, 1KB EEPROM, 2KB SRAM, 54/69 general purpose I/O lines, 32 general purpose working registers, a real-time counter, four flexible timer/counters with compare modes, two USARTs, a byte-oriented 2-wire serial interface, an 8-channel/10-bit A/D converter with optional differential input stage with programmable gain, and more. It operates at a voltage range of 1.8V to 5.5V.

Featuring the powerful AVR RISC architecture, the ATMEGA325PV-10MU executes most instructions in a single clock cycle, achieving throughputs approaching 1 MIPS per MHz. This empowers system designers to optimize power consumption versus processing speed. The device is packaged in a 64-pad QFN surface-mount package, making it suitable for space-constrained applications.

Key features of the ATMEGA325PV-10MU include:

• 32KB of in-system self-programmable flash program memory
• 1KB EEPROM and 2KB internal SRAM
• Up to 20 MIPS throughput at 20MHz
• JTAG (Joint Test Action Group) interface for on-chip-debug
• Two 8-bit timer/counters with separate prescaler and compare mode
• Two 16-bit timer/counters with separate prescaler, compare, and capture mode
• Real Time Counter with separate oscillator
• Four PWM channels
• Programmable serial USARTs
• Master/Slave SPI serial interface
• Byte-oriented 2-wire serial interface (Philips I2C compatible)
• 8-channel, 10-bit ADC with optional differential input stage with programmable gain (TQFP and QFN/MLF)
• Programmable watchdog timer with internal oscillator
• On-chip analog comparator
• Interrupt and wake-up on pin change

With its robust set of peripherals, the ATMEGA325PV-10MU is ideal for a wide array of applications, including industrial control, sensor systems, automotive, and home automation. Its power efficiency and processing capabilities make it a go-to solution for designers who are looking for a versatile and reliable microcontroller.
