Key Features
- 8-bit AVR RISC core at 10 MHz with single-cycle instruction execution for low-power embedded control
- Wide supply voltage range of 1.8 V to 5.5 V enabling battery-powered and 3.3 V or 5 V system designs without level translation
- Integrated 10-bit ADC with 6 channels, UART, SPI, and TWI interfaces plus three timer/counter modules in a prototyping-friendly DIP-28 package
Applications
The ATmega48V suits low-power sensor nodes, home automation controllers, and hobby prototyping projects where the 1.8 V to 5.5 V wide operating voltage extends battery runtime in coin-cell or AA-powered designs. Its DIP-28 package enables direct breadboard and through-hole PCB development without SMD rework tools, making it ideal for educational platforms and rapid prototyping. The 10-bit ADC and hardware UART also support industrial sensor readout and simple RS-232 communication bridges.

Frequently Asked Questions
What supply voltage range does the ATmega48V-10PU support, and how does it affect battery-powered designs?
The ATmega48V-10PU operates from 1.8 V to 5.5 V, making it directly compatible with 2-cell AA alkaline batteries delivering nominally 3 V down to approximately 2 V at end of life, extending battery runtime in wireless sensor nodes and portable measurement tools without a boost regulator.
How much program Flash and SRAM does the ATmega48V provide for embedded firmware?
The ATmega48V provides 4 KB of in-system programmable Flash and 512 bytes of SRAM, with 256 bytes of EEPROM for non-volatile parameter storage, which is sufficient for a sensor acquisition loop, a software UART bootloader, and a simple state machine controlling up to 23 GPIO outputs.
What ADC resolution and channel count does the ATmega48V offer for analog sensing applications?
The ATmega48V integrates a 10-bit successive-approximation ADC with 6 multiplexed input channels and a conversion time of approximately 65 µs at 200 kSPS sample rate, enabling accurate reading of temperature sensors, potentiometers, and current shunts in industrial monitoring applications.
For a beginner microcontroller project, why is the DIP-28 package of the ATmega48V-10PU particularly convenient?
The ATmega48V-10PU uses a 600 mil DIP-28 through-hole package with 2.54 mm pin pitch, fitting directly onto standard breadboards and single-sided prototype PCBs without SMD soldering equipment, making it the preferred choice for students and makers doing hands-on embedded systems learning with AVR toolchains.
When would the ATmega48V-10PU be chosen over the ATmega88 or ATmega168 in a cost-sensitive design?
The ATmega48V-10PU is selected when firmware fits within 4 KB Flash and the lower per-unit cost compared to ATmega88 with 8 KB or ATmega168 with 16 KB matters at high production volumes, for example in disposable medical sensors or consumer electronics accessories where code size has been optimized through careful refactoring.
