Atmel ATMEGA162 8-Bit Microcontroller, 16K Flash, TQFP44

The Atmel ATMEGA162 8-Bit Microcontroller is an 8-bit, high-performance, low-power AVR RISC-based microcontroller with 16K flash memory, supplied in a TQFP44 package. It is designed for embedded system control, combining in-system programmable flash, SRAM and EEPROM storage with an integrated JTAG interface for on-chip debugging and programming.

Overview

The device provides 16 KB of in-system programmable flash memory, 1 KB of SRAM and 512 bytes of EEPROM for both non-volatile and volatile storage. Its RISC architecture executes instructions in a single clock cycle, delivering throughput of up to 16 MIPS at a 16 MHz clock speed. The core includes 32 general-purpose working registers connected directly to the Arithmetic Logic Unit (ALU), supporting high-speed data processing.

Key Features

• Advanced RISC core with single-cycle instruction execution
• Integrated 2-cycle hardware multiplier
• JTAG interface compliant with IEEE 1149.1 for boundary-scan testing and debugging
• Two 8-bit and one 16-bit timer/counter with compare, capture and PWM modes
• Power-on reset, programmable brown-out detection and an internal calibrated RC oscillator
• Five sleep modes: Idle, Power-save, Power-down, Standby and Extended Standby
• 35 I/O lines with SPI and UART serial communication

Operation and Dimensions

The microcontroller operates from a wide voltage range of 2.7 V to 5.5 V, suiting both battery-powered and mains-operated designs. Listed dimensions are width 3.3, depth 1.5 and height 4.3, with a weight of 1.6 gm.
