Overview

Description

ATtiny406-MNR is Microchip’s tinyAVR 1‑series microcontroller in a small package (MNR), designed for ultra‑low‑power, simple embedded tasks.
Key points:
- AVR 8‑bit core, up to ~20 MHz operation.
- Memory: small flash (about 2 KB), RAM around ~128 bytes, EEPROM (a few hundred bytes).
- Peripherals: 10‑bit ADC, PWM/timers, event system, serial interfaces (USI/USART for I2C/SPI/UART), analog comparator, and interrupt/pin‑change features.
- Power: wide supply range with sleep modes and brown‑out detection for battery operation.
- Programming: UPDI (single‑wire) programming (HV programming also supported).
- Packaging: MNR denotes the tiny 8‑pin/compact variant in the 1‑series.
- Use cases: tiny sensors, handheld controls, LED drivers, wearables, capacitive touch, and other low‑pin‑count projects.
- Development: supported in MPLAB X / AVR‑GCC toolchain; consult the datasheet for exact specs and pinout.
Note: exact memory sizes and features can vary by variant; check the ATtiny406 datasheet for precise numbers.

Features

Here are the key features of the ATtiny406-MNR (TinyAVR 0-series, 8-pin package):
- Core: 8‑bit AVR RISC, UPDI programming interface.
- Memory: 4 KB Flash, 256 B RAM, 256 B EEPROM.
- Clock: up to 20 MHz operation at 4.5–5.5 V; up to 8 MHz in 2.7–3.6 V range.
- Peripherals:
- 6-channel 10‑bit ADC with programmable reference.
- Analog comparator; internal reference.
- Timers: one 8‑bit Timer/Counter with PWM; one 16‑bit Timer/Counter with PWM.
- Configurable Custom Logic (CCL) and Event System for peripheral routing.
- Communications: USART (serial) and USI for SPI/I2C.
- Power: multiple sleep modes, wake-up from sleep, Brown‑out Detector, Watchdog Timer.
- Oscillator: internal calibrated RC oscillator options.
- Package: MNR (8-pin device/package).
Note: exact counts and features can vary by package revision; verify with the latest datasheet for your specific lot.

Package

ATTINY406-MNR uses an 8-pin MSOP package (narrow body), i.e., MSOP-8 (about 3x3 mm).

Pinout

- Pin count: 8 pins (8-pin package)
- Function: ATtiny406-MNR is an 8-bit AVR microcontroller (tinyAVR) for small embedded control applications.

Manufacturer

- Manufacturer: Microchip Technology Inc.
- What kind of company: An American multinational semiconductor company that designs and manufactures microcontrollers (including AVR/ATTiny), analog, and memory devices; it acquired Atmel in 2016.

Application

- Ultra-low-power battery-powered sensors and wearables
- Small home-automation/IoT nodes (temp/humidity, light, presence)
- Data logging and environmental monitoring
- Compact displays, user interfaces and indicators
- LED lighting control and simple motor/actuator drive
- Educational, hobby projects and rapid prototyping

Equivalent

Equivalent products are other tinyAVR 0-series devices with similar features:
- ATtiny402
- ATtiny404
- ATtiny202
- ATtiny212
The 402/404 are in the same 4 KB flash family as the 406; 202/212 are the lower-memory options. Package variants (like MNR) differ by package only.
