ATMEGA128A-MU  

Microcontrollers

Microchip Technology's ATMEGA128A-MU is a high-performance microcontroller unit (MCU) that is part of the AVR Enhanced series. This MCU is designed for a wide range of applications, including industrial control, medical devices, and consumer electronics.

Description:

The ATMEGA128A-MU is an 8-bit MCU with a high-density, non-volatile memory. It features a high-speed embedded PI (Parallel Interface) and a JTAG (Joint Test Action Group) interface for programming and debugging. The MCU is available in a 64-pin, 0.150-inch, TQFP (Thin Quad Flat Package) package.

Features:

1. 128KB of In-System Programmable Flash memory with read-while-write capability
2. 8KB of SRAM and 4KB of EEPROM
3. 43 general-purpose I/O lines
4. 16MHz maximum operating frequency
5. 33 programmable interrupt sources
6. Three 16-bit timer/counters with input capture and compare modes
7. Two 8-bit timer/counters with input capture and compare modes
8. Eight-channel, 10-bit ADC with up to 8 analog inputs
9. Two USARTs with multi-purpose SPI/TWI serial interfaces
10. 11-channel DMA controller
11. On-chip debug support with JTAG interface
12. Sleep, power-down, and power-save modes for low-power operation
13. Internal and external crystal oscillator options
14. Watchdog timer with separate clock source

Applications:

The ATMEGA128A-MU is suitable for a wide range of applications, including but not limited to:

1. Industrial control systems
2. Medical devices and equipment
3. Consumer electronics, such as appliances and gaming systems
4. Automotive control systems
5. Telecommunication systems
6. Data acquisition and signal processing systems
7. Robotics and automation
8. Battery management systems
9. Security and surveillance systems
10. Handheld devices and portable electronics
