The device is manufactured using Atmel’s high density non-volatile memory technology.
The On-chip ISP Flash allows the program memory to be reprogrammed In-System
through an SPI serial interface, or by a conventional non-volatile memory programmer.
By combining an 8-bit RISC CPU with In-System Self-Programmable Flash on a monolithic
chip, the Atmel ATtiny2313 is a powerful microcontroller that provides a highly
flexible and cost effective solution to many embedded control applications.
