Built on the modern AVR® processor with a hardware multiplier, it delivers a potent combination of computational power, versatility, and energy efficiency in a compact 14-pin package, making it an ideal solution for a vast array of embedded control applications.
Core Architecture and Performance
At its heart, the ATTINY1614 features the AVR CPU running at up to 20 MHz, capable of executing instructions in a single clock cycle. This allows it to achieve a performance of up to 24 MIPS. The core is augmented with a hardware multiplier, significantly speeding up arithmetic operations. It operates from a wide voltage range of 1.8V to 5.5V, enabling deployment in both 3.3V and 5V systems and facilitating robust operation in battery-powered scenarios.
Memory Configuration
The microcontroller is equipped with integrated memory resources:
16 KB of In-System Self-Programmable Flash Memory for application code.
256 Bytes of EEPROM for storing non-volatile data.
2 KB of SRAM for efficient data handling during operation.
Advanced Peripherals and Features
The ATTINY1614-SSFR stands out with its rich set of sophisticated peripherals:
Event System (EVSYS): Allows peripherals to communicate and trigger actions independently of the CPU, enabling advanced functionality and significantly reducing power consumption.
Custom Logic (CCL): Provides programmable logic blocks to create custom combinatorial or sequential logic functions, offloading simple tasks from the CPU.
12-bit Differential ADC with Computation (ADC): Features a 12-bit Analog-to-Digital Converter with built-in computation, allowing it to perform filtering and oversampling while the CPU is asleep.
16-bit Timers/Counters (TCA/TCB): Multiple versatile timers support PWM generation, input capture, and frequency measurement.
Serial Communications: Includes USART, SPI, and I2C interfaces for seamless connectivity with sensors, displays, and other peripherals.
Hardware Security: Features a Cyclic Redundancy Check (CRC) module and Memory Protection Unit (MPU) for enhanced system integrity and security.
Low-Power Operation
Designed for power-sensitive applications, the ATTINY1614 supports multiple sleep modes, including Idle, Standby, and Power-Down. Its advanced picoPower® technology ensures minimal current draw in active and sleep modes, extending battery life in portable devices.
