ATMEGA88V-10AUR

Overview

The ATMEGA88V-10AUR is a low-power CMOS 8-bit microcontroller based on the AVR enhanced RISC architecture. It features 8 Kbytes of In-System Self-Programmable Flash, 512 bytes EEPROM, and 1 Kbyte Internal SRAM. The device operates at speeds up to 10 MHz with a supply voltage range of 1.8 V to 5.5 V. It includes 23 programmable I/O lines, an 8-channel 10-bit ADC, three Timer/Counters, USART, SPI, and TWI interfaces. Packaged in a 32-lead TQFP (32A), it supports industrial temperature ranges from -40°C to +85°C.

Feature Summary

• Advanced RISC Architecture with 131 powerful instructions and fully static operation for optimized power consumption versus processing speed.
• In-System Self-Programmable Flash memory with true Read-While-Write capabilities and optional boot code section.
• Integrated peripheral set including an 8-channel 10-bit ADC, multiple timer/counters, and serial communication interfaces.
• Support for capacitive touch sensing via QTouch library integration for buttons, sliders, and wheels.

Applications

• Embedded control applications requiring low power consumption and high performance.
• Systems utilizing capacitive touch interfaces such as buttons, sliders, or wheels.
• Industrial environments operating within the specified temperature range.
• Applications requiring in-system programming and read-while-write flash operations.

Procurement Notes

Verify component authenticity through official Microchip channels. Confirm package type matches the 32-lead TQFP specification. Ensure compliance with RoHS directives and lead-free requirements. Check for any specific ordering suffix variations that may affect packaging or lead finish. Validate operational parameters against system design constraints before procurement.

Selection Notes

Select this model for designs requiring 8 Kbytes of Flash and 1 Kbyte of SRAM within a compact 32-pin package. The 'V' suffix indicates support for lower voltage operation down to 1.8 V. The '10' suffix specifies the maximum clock frequency rating. Consider the TQFP package for surface mount assembly needs. Evaluate power consumption requirements against active and sleep modes.
