Overview
The ATMEGA88PB-MUR is an 8-bit AVR microcontroller featuring 8 kB of in-system self-programmable Flash, 1 kB of internal SRAM, and 512 bytes of EEPROM. It operates at a maximum frequency of 20 MHz with a supply voltage range of 1.8 V to 5.5 V. The device includes an 8-channel 10-bit ADC, six PWM channels, one USART, one SPI interface, and one TWI (I²C) interface. It utilizes a 32-pin VFQFN package.
Feature Summary
- Supports True Read-While-Write operation for simultaneous code execution and memory programming.
- Integrates QTouch library capabilities for capacitive touch sensing applications.
- Provides multiple software-selectable power-saving modes including Power-down and Idle.
- Features core-independent peripherals and PicoPower technology for optimized energy efficiency.
Applications
- Embedded control systems requiring low-power operation
- Capacitive touch interface implementations
- Battery-powered consumer electronics
- Industrial monitoring devices
Procurement Notes
Verify the specific speed grade and temperature rating required for your application against the datasheet specifications. Confirm that the 32-pin VFQFN package dimensions match your PCB footprint design. Ensure compatibility with existing development tools and compilers for the AVR architecture before finalizing procurement.
Selection Notes
Select this component when 8 kB of program memory and 1 kB of RAM are sufficient for the application logic. Consider the 20 MHz operating speed and 1.8 V to 5.5 V supply range requirements. Evaluate the need for the specific peripheral set, including the 8-channel ADC and communication interfaces, relative to other variants in the ATmega48PB/168PB family.
Part Context
This part belongs to the ATmega48PB/88PB/168PB series, which shares a common architecture and peripheral set differentiated primarily by memory sizes. The PB suffix indicates the inclusion of Core Independent Peripherals and enhanced features compared to older A-series variants. It is designed for cost-effective embedded solutions using the AVR RISC architecture.
Replacement Considerations
ATMEGA88PB-MU is a pin-compatible alternative in a tray package. ATMEGA88PA-MNR offers similar specifications but may differ in manufacturing process or revision. Verify electrical characteristics and firmware compatibility when substituting.
