Microcontrollers

The ATTINY85-20SU is a microcontroller unit (MCU) manufactured by Microchip Technology. It is a part of the AVR Enhanced series of 8-bit MCUs and is based on the low-power AVR RISC architecture. The ATTINY85-20SU is available in a 20-pin SOIC (Small Outline Integrated Circuit) package.

Description:

The ATTINY85-20SU is a low-power, high-performance microcontroller with 8 KB of In-System Programmable Flash memory, 512 bytes of EEPROM, and 512 bytes of SRAM (Static Random Access Memory). It operates at a supply voltage range of 2.7 V to 5.5 V and has a wide operating temperature range of -40°C to +85°C.

Features:

1. 8-bit RISC CPU with 16 general-purpose working registers.
2. Up to 8 KB of In-System Programmable Flash memory for program and data storage.
3. 512 bytes of EEPROM for non-volatile data storage.
4. 512 bytes of SRAM for temporary data storage.
5. Internal calibrated RC oscillator with a frequency range of 1.0 MHz to 20.0 MHz.
6. I/O lines with optional internal pull-up resistors.
7. Six interrupt priority levels for efficient interrupt handling.
8. Sleep mode for low-power consumption during periods of inactivity.
9. Two 8-bit Timer/Counters with PWM and phase-corrected PWM modes.
10. USART for serial communication with support for SPI and TWI (I2C) interfaces.
11. ADC (Analog-to-Digital Converter) with up to 8 channels.
12. Internal and external interrupts with configurable interrupt priorities.
13. Brown-out detection and reset feature.
14. In-System Programming (ISP) and In-Application Programming (IAP) capabilities.
