Overview
The ATMEGA88PB-MNR is an 8-bit AVR microcontroller featuring 8KB of in-system programmable Flash, 1KB SRAM, and 512B EEPROM. It operates at up to 20MHz with a supply voltage range of 1.8V to 5.5V. The device includes 27 I/O pins, an 8-channel 10-bit ADC, three Timer/Counters, USART, SPI, and TWI interfaces. It utilizes a 32-pin VFQFN package (5x5mm) and supports industrial temperatures from -40°C to +105°C.
Feature Summary
- Supports True Read-While-Write self-programming for continuous code execution during memory updates.
- Integrates PicoPower technology with six selectable sleep modes to optimize power consumption.
- Includes QTouch library support for capacitive touch sensing applications.
Applications
- Embedded control systems requiring low power operation
- Industrial automation controllers
- Capacitive touch interface devices
Procurement Notes
Verify the specific ordering suffix 'MNR' corresponds to the tape and reel packaging format as indicated in official Microchip documentation. Confirm that the speed grade matches the required operational frequency for your voltage and temperature conditions. Ensure compatibility with existing PCB footprints for the 32-pad VFQFN package.
Selection Notes
Select this component when 8KB program memory and 27 general-purpose I/O lines are sufficient for the application. Consider the ATmega88PB series for its enhanced peripheral features compared to standard variants. Verify that the industrial temperature range meets environmental requirements.
Part Context
This part belongs to the ATmega48PB/88PB/168PB family, which shares identical pinouts and core architectures but differs in memory sizes. The ATmega88PB variant specifically provides 8KB Flash and 1KB SRAM, bridging the gap between the 4KB and 16KB options within the PB series.
