Overview

Description

ATtiny25-15SZ is an 8‑bit AVR microcontroller from Atmel/Microchip, part of the TinyAVR family. It’s designed for compact, low‑power applications and fits in an 8‑pin package (SZ denotes the package/silks). The “-15” suffix indicates a 15 MHz maximum clock.
Key specs (typical):
- Memory: 2 KB flash program memory, 128 bytes RAM, 128 bytes EEPROM.
- I/O: small number of I/O lines across two ports (8 I/O pins total).
- Peripherals: ADC (10-bit, multiple channels), timers/counters, and a USI serial interface (used for SPI/I2C), plus watchdog and various sleep modes for low power.
- Power and clock: operates from ~1.8 V to 5.5 V; up to 15 MHz clock (speed/power dependent).
- Programming: in‑system programmable via SPI; supported by standard AVR toolchain (GCC, avrdude, etc.).
Applications: simple sensors, LED/motor control, small timers, hobby/educational projects, where a tiny, low‑cost MCU is sufficient.

Features

Key features of ATtiny25-15SZ (8-pin AVR):
- 8-bit AVR RISC microcontroller
- Program memory: 2 KB Flash
- RAM: 128 bytes; EEPROM: 256 bytes
- I/O: 6 general-purpose I/O pins
- Timers: Timer/Counter0 (8-bit with PWM) and Timer/Counter1 (16-bit)
- Analog: 10-bit ADC (2 channels) + analog comparator
- Serial/communication: USI for SPI/I2C (TWI)
- Clock and voltage: up to 15 MHz at 5V; operating voltage 1.8–5.5 V; internal 8 MHz RC oscillator plus clock options
- Power/low‑power: Brown-out detector; Watchdog timer; multiple sleep modes (Idle, ADC Noise Reduction, Power-down, Standby)
- In-system programming: via SPI; debugWIRE option on reset
- Package: 8-pin (SZ suffix denotes small 8-pin package, e.g., SOIC-8/related)
Ideal for compact, low-power applications requiring modest memory and peripherals.

Package

An 8-pin Small Outline Integrated Circuit (SOIC) package.

Pinout

- Pin count: 8 pins (SZ = 8-pin SOIC package)
- Function: ATtiny25 is an 8-bit AVR microcontroller with 5 I/O pins on Port B (PB0–PB4) plus Reset, Vcc and GND. It includes ADC, timers, and a serial interface (USI) for SPI/I2C-style communication, suitable for simple embedded control tasks.

Manufacturer

- Manufacturer: Microchip Technology Inc. (the current maker of the ATtiny line, including ATTINY25-15SZ; Atmel was acquired by Microchip in 2016).
- What kind of company: A global semiconductor company that designs, manufactures, and sells embedded microcontrollers and other ICs (analog, memory, etc.); publicly traded (NASDAQ: MCHP), headquartered in Chandler, Arizona.

Application

- Small, low-power battery-powered controllers
- Sensor interfacing and data acquisition (ADC)
- LED driving and PWM-based motor control
- Displays, indicators, and simple user interfaces (buttons, keypads)
- Remote controls, IR receivers, and wireless sensor nodes
- Simple data logging with EEPROM; hobbyist/educational/Arduino-like projects

Equivalent

Closest equivalents in the AVR Tiny family (8-pin, 15 MHz) are:
- ATtiny25-15SU
- ATtiny45-15SU
- ATtiny85-15SU
These share the same memory footprint and peripherals with the ATtiny25-15SZ in an 8-pin package; their main differences are I/O/configurations and available peripherals.
