Atmel ATMEGA88-20AU 8-bit AVR Microcontroller TQFP32

The Atmel ATMEGA88-20AU 8-bit AVR Microcontroller is a low-power, 8-bit AVR RISC-based microcontroller with 8 kB of in-system programmable flash memory, supplied in a TQFP32 package.

Overview

The ATMEGA88-20AU integrates 8 kB of in-system programmable (ISP) flash memory, 1 kB of SRAM, and 512 B of EEPROM for data handling. It includes an 8-channel, 10-bit analogue-to-digital converter and the debugWIRE interface, which supports on-chip debugging during development and troubleshooting. The device delivers a throughput of 20 MIPS at 20 MHz and operates across a voltage range of 2.7 V to 5.5 V.

The core contains 32 general-purpose working registers, all directly connected to the Arithmetic Logic Unit (ALU). This allows two independent registers to be accessed in a single clock cycle. The advanced RISC architecture executes instructions in a single clock cycle and achieves nearly 1 MIPS per MHz, balancing processing speed with controlled power consumption for demanding embedded applications.

Key Features

• Advanced RISC architecture with an on-chip two-cycle multiplier for fast mathematical operations.
• High-endurance, non-volatile memory segments for reliable data storage.
• Support for the QTouch library, enabling capacitive touch buttons, sliders, and wheels.
• Real-time counter with a separate oscillator for accurate timing.
• Power management with power-on reset, programmable brown-out detection, an internal calibrated oscillator, and five selectable sleep modes: Idle, ADC noise reduction, Power-save, Power-down, and Standby.
• 23 programmable I/O lines with extensive interrupt capabilities.

Physical Details

The device is housed in a compact TQFP32 (Thin Quad Flat Pack) package with a stated weight of 1.6 gm and dimensions of 3.3 (width) x 1.5 (depth) x 4.3 (height).
