ATMEGA88V-15MT

Overview

The ATMEGA88V-15MT is an automotive-grade 8-bit AVR microcontroller featuring 8 Kbytes of in-system programmable Flash, 512 bytes of EEPROM, and 1 Kbyte of SRAM. It operates within a voltage range of 2.7 V to 5.5 V and supports clock frequencies up to 16 MHz at the upper voltage limit. The device utilizes a 32-lead TQFP or QFN package and provides 23 programmable I/O lines. It includes six PWM channels, an 8-channel 10-bit ADC, three Timer/Counters, USART, SPI, and TWI interfaces.

Feature Summary

• Automotive quality grade compliant with ISO-TS-16949 and AEC-Q100 standards
• Advanced RISC architecture delivering up to 1 MIPS per MHz throughput
• Non-volatile memory with read-while-write capabilities for continuous operation during programming
• Five software-selectable power-saving modes including Idle, Power-down, and Standby

Applications

• Automotive embedded control systems requiring high reliability
• Industrial applications operating in extended temperature environments
• Battery-powered devices utilizing low-power consumption modes
• General-purpose microcontroller tasks involving sensor interfacing and data acquisition

Procurement Notes

Verify the specific suffix 'MT' against official Microchip documentation to confirm package type and temperature grade. Ensure the ordering code matches the required automotive qualification level. Confirm availability through authorized distributors as lead times may vary based on production schedules.

Selection Notes

Select this component when automotive reliability standards are mandatory. The 16 MHz speed grade suits applications needing moderate processing power without excessive heat generation. Consider the 32-lead package constraints for PCB layout. Verify that the 2.7 V minimum voltage aligns with the system's power supply design.

Part Context

This part belongs to the ATmega48/88/168 Automotive family, manufactured under strict quality controls. It shares the core AVR CPU architecture with industrial variants but offers enhanced thermal and electrical robustness. The 'V' suffix typically denotes a lower voltage variant, while '15' indicates the speed grade.
