Atmel ATmega16A 8-bit Microcontroller Datasheet
The ATmega16A is a low‑power CMOS 8‑bit microcontroller based on Atmel's AVR enhanced RISC architecture. It offers up to 16 MIPS at 16 MHz, 16 KB of flash, 512 B EEPROM, 1 KB SRAM, and a rich set of peripherals including multiple timers, a 10‑bit ADC, USART, SPI, I²C, and JTAG debugging.
The document details pin‑out for PDIP, TQFP and QFN/MLF packages, electrical limits (2.7‑5.5 V, 0‑16 MHz), power‑down consumption (<1 µA), and extensive register descriptions. It also covers programming methods, boot‑loader support, and timing diagrams for all major modules.
