ATTINY461-15SZ Description

Short technical summary and product information.

The ATTINY461-15SZ is an 8-bit AVR microcontroller from Microchip Technology, part of the ATtiny series. It features 4KB of in-system programmable Flash memory with 10,000 write/erase cycles, 256B of SRAM, and 256B of EEPROM with 100,000 write/erase cycles. The device operates at a maximum clock frequency of 16MHz when supplied with 4.5V to 5.5V, and 8MHz over the full 2.7V to 5.5V supply range.

 

This microcontroller integrates a rich set of peripherals including an 11-channel 10-bit ADC with differential inputs and programmable gain, a universal serial interface (USI), two timer/counters with PWM outputs, an on-chip analog comparator, and a programmable watchdog timer. It also features brown-out detection, power-on reset, and internal calibrated oscillator.

 

Housed in a 20-lead SOIC package (0.295" body width, 7.50mm pitch), the ATTINY461-15SZ supports surface mount assembly and operates over the automotive temperature range of -40°C to +125°C. The device is qualified to AEC-Q100 automotive standards and is suitable for demanding environmental conditions.
