概述

Description

Here’s a concise intro to the ATtiny25-20PU:
- What it is: An 8‑bit AVR microcontroller (ATtiny25/45/85 family) from Atmel/Microchip, housed in an 8-pin DIP. The “-20” suffix means it supports up to a 20 MHz clock; “PU” denotes the DIP packaging.
- Core specs: 2 KB flash program memory, 128 bytes RAM, 128 bytes EEPROM.
- Peripherals: 1x 8-bit Timer/Counter0 with PWM, 1x 16-bit Timer/Counter1, 4-channel 10-bit ADC, analog comparator, USI serial interface (SPI/I2C), watchdog timer, brown‑out detector, multiple sleep modes.
- I/O and power: about 6 general-purpose I/O pins in the 8-pin package; operates from 1.8–5.5 V (at 20 MHz, typically 2.7–5.5 V).
- Programming and tooling: programmed via SPI; supported by AVR-GCC, Atmel Studio, and AVRDUDE.
- Applications: tiny, low-cost, low-power tasks—LED drivers, sensors, simple control loops, battery-powered gadgets.
- Pros/cons: Small footprint, cheap, easy for simple projects; limited memory and peripherals compared to larger AVRs.

Features

ATTINY25-20PU (20‑pin PDIP) features:

- ADC: 10‑bit ADC with 4 input channels
- Analog comparator
- Serial interface: USI for SPI/I2C communication
- Power management: multiple sleep modes (Idle, ADC Noise Reduction, Power‑down), watchdog timer, brown‑out detector
- Programming: In‑system programming via SPI (ISP)
- Package: 20‑pin PDIP (ATTINY25-20PU)
Optional programming/debug features may vary; refer to the datasheet for exact specifications and voltage/frequency recommendations.

Package

Plastic DIP (through-hole) 14-pin package.

Pinout

- Pin count: 14 pins (PDIP-14 / DIP package)
