ATTINY26-16SJ is an 8-bit AVR microcontroller developed by ATMEL. It has 8K Bytes of In-System Programmable Flash, 384 Bytes EEPROM, 512 bytes SRAM memory, and 27 programmable I/O pins. It has a wide operation voltage range of 2.7-5.5V and a small operating temperature range of -40℃ to +125℃ . Its integrated workload efficiency and low power consumption make it suitable for application field that require low power consumption and tiny size controllers, such as home appliances, small monitoring systems, industrial automation, etc.

ATTINY26-16SJ uses a stackless fixed 16-bit RISC microcontroller architecture, a single cycle Hardware Multiplier, enhanced on-chip debugging and a two way read/write instruction. It uses a single CPU core with three operating modes to enable the user to switch between single cycle control or extended instruction when needed, the operating modes are easy to configure. The AVR core features 32 different registers which enable fine-grained control over the flow of data and instruction execution.

The working principle of ATTINY26-16SJ mainly involves enabling the user to program specific instructions into the microcontroller, which subsequently control and manage the data flow and instruction execution. The main application field of ATTINY26-16SJ is in low power consumption products, small monitoring devices, smart home appliances, industrial and auto pilot systems, etc. The instructions consist of instructions for the AVR core, instructions for the peripherals, instructions for the I/O components, instructions for the system clock, instructions to manage the RAM, instructions for interrupts and instructions for data transmission and reception.

The chip works as a Translation Look-aside Buffer (TLB) to enable the processor to index and address memory locations. The chip supports a variety of input/output peripherals such as USART, UART, SPI, PWM, etc. The chip is also capable of accessing external memory for data storage and transferring data to the main processor. Additionally, it supports an advanced battery operating capacity which allows debugging and configurations without the need of an external power source.

This chip also features an external reset pin and an internal reset circuit. The external reset pin allows the user to soft reset or hard reset the microcontroller. The internal reset circuit is designed to detect certain problems such as sleep mode, power supply overload, etc. and will trigger a reset if anything is found to be abnormal.

In conclusion, ATTINY26-16SJ is built on an 8-bit AVR core with a RISC microcontroller architecture. It supports different input/output peripherals and supports an internal reset circuit. It is suitable for applications that require low power consumption and tiny size controllers and therefore is mainly used in home appliances, small monitoring systems and industrial automation.
