ATTINY1617-MNR 8-bit AVR MCU
The ATTINY1617-MNR is a high-performance, low-power 8-bit AVR® RISC-based microcontroller from Microchip Technology, part of the tinyAVR® 1-series family optimized for compact embedded control applications. This device integrates 16KB of ISP Flash memory, 256 bytes of EEPROM, and 2KB of SRAM, all accessible via a high-speed 2-cycle core running at up to 20MHz. Housed in a 24-VQFN wettable flank package with an exposed pad for improved thermal performance, the ATTINY1617-MNR operates from a supply voltage range of 1.8V to 5.5V and is specified over an extended industrial temperature range of -40°C to +105°C. The microcontroller features a 10-bit differential ADC with programmable gain, a configurable custom logic (CCL) block, a hardware CRC module, and a full suite of timer/counter and communication peripherals including USART, SPI, and TWI (I²C), making it an ideal solution for sensor nodes, small actuator controllers, and human-interface subsystems in space-constrained designs.
Key Features and Specifications
The ATTINY1617-MNR delivers a rich peripheral set with a 12-channel 10-bit ADC supporting single-ended and differential measurements with internal 1×/16× gain options, enabling precise analog signal acquisition without external amplifiers. It includes two 16-bit Timer/Counters (TCA and TCB) with waveform generation and input capture, one 8-bit Timer/Counter type D (TCD) optimized for motor control applications, and an RTC with separate clock source for timekeeping. The Configurable Custom Logic (CCL) block provides up to four look-up tables (LUTs) and a sequencer that can implement combinatorial/sequential glue logic internally, reducing external component count. Communication interfaces comprise one USART with fractional baud rate generator, one SPI, and one I²C/TWI slave/master. The device also integrates a programmable brown-out detector (BOD), power-on reset (POR), and a 24-bit CRC scan engine for runtime Flash integrity verification. Event System (EVSYS) allows peripheral-to-peripheral signaling without CPU intervention, lowering latency and power draw.
Alternative MCUs
● ATTINY1617-MF: Microchip 24-pin VQFN (4×4 mm) variant with standard (non-wettable flank) package option, offering identical 16KB Flash, 2KB SRAM, and peripheral set as the ATTINY1617-MNR for designs not requiring wettable flanks.
● ATTINY3217-MNR: Higher-memory member of the same tinyAVR 1-series in 24-pin VQFN, featuring 32KB Flash and 4KB SRAM with identical peripherals, ideal for applications needing more code space.
● ATTINY817-MNR:Lower-memory 8KB Flash / 512B SRAM variant in the same 24-pin VQFN package and peripheral architecture, offered as a cost-optimized option for simpler control tasks.
● ATMEGA328P-AU: Classic 8-bit AVR with 32KB Flash in TQFP-32; not pin-compatible but functionally richer in legacy AVR ecosystem, sometimes chosen when more established toolchains or larger packages are acceptable.
