Overview
The ATMEGA88PB-MN is an 8-bit AVR microcontroller featuring 8KB of in-system programmable Flash, 1KB SRAM, and 512B EEPROM. It operates at a maximum clock frequency of 20MHz with a supply voltage range of 1.8V to 5.5V. The device includes 27 programmable I/O pins, an 8-channel 10-bit ADC, and three Timer/Counters. It utilizes a 32-pin VFQFN package and supports industrial operating temperatures from -40°C to +105°C.
Feature Summary
- Supports QTouch library for capacitive touch sensing applications
- Features Core Independent Peripherals (CIP) for low-power background tasks
- Includes True Read-While-Write capability for non-volatile memory operations
- Integrates PicoPower technology for optimized power consumption
Applications
- Capacitive touch interface implementations
- Industrial sensor nodes requiring extended temperature ranges
- Battery-powered embedded control systems
- Low-power consumer electronics
Procurement Notes
Verify the specific suffix 'MN' corresponds to the 32-pin VFQFN package and the -40°C to +105°C industrial temperature grade. Confirm RoHS compliance status as indicated in official documentation. Ensure ordering codes match the required speed grade and voltage specifications for the target application environment.
Selection Notes
Select this component when high-speed processing up to 20MHz is required alongside extensive I/O capabilities. The VFQFN package suits space-constrained designs. Consider the PB series features like CIP if background task offloading is necessary. Verify compatibility with existing development tools and compilers for the AVR architecture.
