ATTINY25V-10SU

The ATTINY25V-10SU is a high-performance, low-power 8-bit AVR microcontroller from Microchip Technology. It features an advanced RISC architecture with 120 instructions, most executing in a single clock cycle, and includes 32 x 8 general-purpose working registers. The device provides 2KB of in-system programmable Flash memory, 128B of SRAM, and 128B of EEPROM, with endurance ratings of 10,000 write/erase cycles for Flash and 100,000 for EEPROM.

This microcontroller operates at a maximum speed of 10MHz and supports a supply voltage range of 1.8V to 5.5V. It includes a 10-bit ADC with 4 single-ended channels, a USI (Universal Serial Interface) for connectivity, and peripherals such as brown-out detection, power-on reset, PWM, and a watchdog timer. The device also features an internal calibrated oscillator, eliminating the need for external clock components.

The ATTINY25V-10SU is housed in an 8-SOIC surface-mount package with a width of 5.30mm. It operates over an industrial temperature range of -40°C to +85°C. Typical active mode current is 300 µA at 1MHz and 1.8V, and power-down mode current is 0.1 µA at 1.8V, making it suitable for battery-powered and low-power applications.

With six programmable I/O lines and a compact package, this microcontroller is well-suited for space-constrained embedded designs requiring basic control, sensing, and communication functions.
