Frequently Asked Questions
How much Flash and SRAM does the ATmega16L-8PI provide, and what clock speed does it run at?
The ATmega16L-8PI includes 16 KB of Flash program memory and 1 KB of SRAM, running at a maximum clock frequency of 8 MHz. This combination supports moderately complex real-time control firmware and is sufficient for applications ranging from sensor interfacing to basic motor control.
What supply voltage range does the ATmega16L-8PI accept, and is it compatible with 3.3 V microcontroller systems?
The ATmega16L-8PI operates from 2.7 V to 5.5 V, making it compatible with both 3.3 V and 5 V systems without requiring level shifters. The wide supply range also makes it suitable for battery-powered designs using two or three AA cells or a single-cell LiPo with a boost converter.
For a 40-pin DIP prototyping board, which built-in communication peripherals can the ATmega16L-8PI use?
The ATmega16L-8PI integrates a UART, SPI, and TWI (I2C-compatible 2-wire) interface directly on-chip, along with an 8-channel 10-bit ADC. These built-in peripherals allow direct connection to sensors, displays, and wireless modules on a standard 40-pin DIP breadboard without additional interface ICs.
