The ATtiny13 is a low‑power 8‑bit AVR microcontroller with 1 KB Flash, 64 B EEPROM, 64 B SRAM and up to 20 MHz operation.
ATtiny13 is an 8‑bit AVR® microcontroller built on an enhanced RISC core. It offers a rich instruction set, single‑cycle execution, 32 general‑purpose registers, and integrated peripherals such as a programmable watchdog, 4‑channel 10‑bit ADC, and an 8‑bit timer with PWM channels. The device is available in 8‑pin PDIP/SOIC packages and supports in‑system programming via SPI.
The datasheet details the pin configuration, electrical characteristics, memory organization, and revision history. It also provides programming guidelines, example code, and errata for various silicon revisions, helping developers design reliable low‑power applications. This manual is written in Chinese.
