ATmega2560 Datasheet – 8-bit Microcontroller – Atmel

Part Number: ATmega2560, ATmega2560-16AU

Function : 8-bit Atmel Microcontroller with 16/32/64KB In-System Programmable Flash

Package: TQFP 100,  CBGA 100 Type

Manufacturer: ATmel




The ATmega2560 is a low-power CMOS 8-bit microcontroller based on the AVR enhanced RISC architecture. By executing powerful instructions in a single clock cycle, the ATmega640 / 1280 / 1281 /  ATmega2560 / 2561 achieves throughputs approaching 1 MIPS per MHz allowing the system designer to optimize power consumption versus processing speed.

The high-performance, low-power Microchip 8-bit AVR RISC-based microcontroller combines 256 KB ISP flash memory, 8 KB SRAM, 4 KB EEPROM, 86 general purpose I/O lines, 32 general purpose working registers, real-time counter, six flexible timer/counters with compare modes, PWM, four USARTs, byte-oriented Two-Wire serial interface, 16-channel 10-bit A/D converter, and a JTAG interface for on-chip debugging.

PIC16F74 Datasheet PDF – 8-bit CMOS FLASH Microcontroller

Part Number: PIC16F74

Function: 8-bit CMOS FLASH Microcontroller, FLASH=4K, data=192, USART, PWM, ADC, 20MHz

Package: DIP 40 Pin Type, QFP, PLCC 44 Type

Manufacturer: Microchip Technology


PIC16F74 datasheet



This powerful (200 nanosecond instruction execution) yet easy-to-program (only 35 single word instructions) CMOS FLASH-based 8-bit microcontroller packs Microchip’s powerful PIC® architecture into an 40- or 44-pin package and is upwards compatible with the PIC16C5X, PIC12CXXX and PIC16C7X devices. The PIC16F74 features 8 channels of 8-bit Analog-to-Digital (A/D) converter with 2 additional timers, 2 capture/compare/PWM functions and the synchronous serial port can be configured as either 3-wire Serial Peripheral Interface (SPI™) or the 2-wire Inter-Integrated Circuit (I²C™) bus and a Universal Asynchronous Receiver Transmitter (USART).

PIC16F73, PIC16F76 devices are available only in 28-pin pack ages, while PIC16F74/77 devices are available in 40-pin and 44-pin packages.


• High performance RISC CPU

• Only 35 single word instructions to learn

• All single cycle instructions except for program branches which are two-cycle
