ATMEL ATMEGA16-16PU 8-bit AVR MCU, 16KB Flash, DIP40

The ATMEL ATMEGA16-16PU is a high-performance, low-power 8-bit microcontroller, utilising an advanced AVR RISC architecture to deliver exceptional efficiency and speed. It integrates 16KB of in-system programmable flash memory for flexible code storage, 1KB of SRAM for data handling, and 512 bytes of EEPROM for non-volatile parameter storage. With a throughput of 16 MIPS at 16 MHz, it executes powerful instructions in a single clock cycle, achieving a performance of nearly 1 MIPS per MHz.

The core features 32 general-purpose working registers, all directly connected to the Arithmetic Logic Unit (ALU). This design allows two independent registers to be accessed within a single instruction cycle, creating a highly code-efficient architecture that can be up to ten times faster than conventional CISC microcontrollers.

Key Technical Features:

• Advanced RISC Core: Includes an on-chip two-cycle multiplier for fast arithmetic operations.
• Rich Peripheral Set: Features an 8-channel, 10-bit A/D converter, two 8-bit timer/counters, and one 16-bit timer/counter with capture and compare modes.
• Communication Interfaces: Supports I2C, SPI, and UART for versatile system connectivity.
• Debugging & Programming: Includes a JTAG (IEEE 1149.1 compliant) interface for on-chip debugging and boundary-scan capabilities.
• Robust System Control: Equipped with power-on reset (POR), programmable brown-out detection, an internal calibrated RC oscillator, and multiple internal and external interrupt sources.
• Power Management: Offers six sleep modes—Idle, ADC Noise Reduction, Power-save, Power-down, Standby, and Extended Standby—for optimal power efficiency in battery-sensitive applications.

Operating from a 4.5V to 5.5V supply and across a broad temperature range from -40°C to 85°C, this 40-pin DIP package microcontroller is engineered for reliability in demanding environments.
