ATMEGA88V-10AU

Overview

The ATMEGA88V-10AU is a low-power CMOS 8-bit microcontroller based on the AVR enhanced RISC architecture, manufactured by Microchip Technology. It features 8KB of In-System Self-Programmable Flash, 512 bytes of EEPROM, and 1KB of internal SRAM. The device supports an operating voltage range of 1.8V to 5.5V and operates at frequencies up to 10MHz within this range. It includes 23 programmable I/O lines, six PWM channels, an 8-channel 10-bit ADC, and communication interfaces such as SPI, USART, and TWI (I2C). The component utilizes a 32-lead Thin Plastic Quad Flat Package (TQFP) with industrial temperature ratings.

Feature Summary

• Advanced RISC Architecture: Executes powerful instructions in a single clock cycle for high throughput efficiency.
• High Endurance Non-volatile Memory: Supports 10,000 Flash write/erase cycles and 100,000 EEPROM write/erase cycles.
• Low Power Consumption: Offers multiple software-selectable power-saving modes including Idle, Power-down, and Standby.
• On-chip Debugging and Programming: Enables In-System Programming via SPI and supports debugWire interface.

Applications

• Industrial control systems requiring robust performance at low voltages
• Consumer electronics utilizing capacitive touch sensing interfaces
• Sensors and instrumentation applications needing analog-to-digital conversion
• Embedded control solutions optimizing power consumption versus processing speed

Procurement Notes

Verify the specific ordering code against official Microchip documentation to ensure compatibility with required package types and lead finishes. Confirm that the 'V' suffix indicates the extended 1.8V operating voltage range suitable for your design. Check current lifecycle status, as older revisions may be marked as Not Recommended for New Designs (NRND). Ensure environmental compliance requirements match the RoHS directive specifications provided in the datasheet.

Selection Notes

Select the ATMEGA88V-10AU when designs require operation down to 1.8V, distinguishing it from standard variants limited to 2.7V minimum. Consider the 32-pin TQFP package if surface-mount assembly with moderate pin density is preferred over QFN or PDIP options. Evaluate memory requirements carefully, as this model provides 8KB Flash and 1KB SRAM, which may necessitate larger variants like the ATmega168V for more complex applications.

Part Context

This microcontroller belongs to the ATmega48/V/88/V/168/V family, designed for cost-effective embedded control applications. The 'V' designation specifically denotes support for lower supply voltages starting at 1.8V, expanding usability in battery-powered devices. Manufactured using high-density non-volatile memory technology, these devices balance processing speed with energy efficiency through picoPower techniques.

Replacement Considerations

Direct functional replacements within the same voltage range include the ATMEGA88V-20AU for higher frequency needs. For legacy designs, verify if the non-V variant ATMEGA88-10AU is acceptable if the 1.8V minimum is not required. Always consult the latest Microchip product change notices to confirm pinout and electrical characteristic consistency before substituting components.
