Microcontrollers

The ATMEGA48-20MU is a microcontroller unit (MCU) manufactured by Microchip Technology. It is part of the ATmega family of 8-bit AVR microcontrollers, which are known for their high performance, low power consumption, and versatility.

Description:

The ATMEGA48-20MU is an 8-bit microcontroller with a maximum operating frequency of 20 MHz. It is housed in a 28-pin, 0.3" μMAX package, which is a small-outline integrated circuit (SOIC) package with a μ-exposed pad for heat dissipation.

Features:

1. 4,096 bytes of in-system programmable flash memory for storing the program code.
2. 256 bytes of static RAM (SRAM) for temporary data storage.
3. 256 bytes of EEPROM for non-volatile data storage.
4. 23 general-purpose input/output (GPIO) pins for interfacing with external devices.
5. 8-bit analog-to-digital converter (ADC) with up to 8 channels for analog signal processing.
6. 2-channel 8-bit pulse-width modulator (PWM) for generating PWM signals.
7. 2-channel 8-bit timer/counter with input capture and output compare for time measurement and pulse generation.
8. USART for serial communication with other devices.
9. Internal calibrated oscillator for precise clock generation.
10. Sleep mode for low-power operation during periods of inactivity.
