ATTINY461-15SZ

Overview

The ATTINY461-15SZ is an automotive-grade, 8-bit AVR microcontroller featuring a 20-pin SOIC package. It provides 4KB of in-system programmable Flash memory, 256 bytes of EEPROM, and 256 bytes of internal SRAM. The device operates at speeds up to 15MHz within the automotive temperature range of -40°C to +125°C. Key peripherals include an 11-channel 10-bit ADC, two timers/counters, and a universal serial interface.

Feature Summary

• Automotive qualified per AEC-Q100 Grade 1 standards for high reliability
• Advanced RISC architecture with single-cycle execution capability
• Integrated analog comparator and programmable watchdog timer
• Supports in-system programming via SPI port

Applications

• Automotive electronic control units
• Sensors and actuators in vehicle systems
• Body electronics modules
