ATMEGA1281V-8MUR 詳細描述
Product Overview
The ATMEGA1281V-8MUR is a Microchip Technology AVR ATmega microcontroller intended for embedded control applications. It uses an 8-bit AVR core operating at 8 MHz and provides 128 KB (64K x 16) of FLASH program memory, 8K x 8 RAM, and 4K x 8 EEPROM. The device supports a 1.8 V to 5.5 V supply range, includes an internal oscillator, and offers 54 I/O pins. Communication options include EBI/EMI, I2C, SPI, and UART/USART, while on-chip peripherals include PWM, brown-out detect/reset, power-on reset, and a watchdog timer. An 8-channel 10-bit A/D converter is available for analog input tasks. The component is supplied in a surface-mount 64-QFN (9x9) package with an exposed pad and is rated for an operating temperature range of -40°C to +85°C (TA).
Key Features
- 8-bit AVR core with an 8 MHz operating speed and 128 KB (64K x 16) FLASH program memory.
- 54 I/O pins and multiple serial interfaces, including EBI/EMI, I2C, SPI, and UART/USART.
- 8K x 8 RAM and 4K x 8 EEPROM for volatile and nonvolatile data storage.
- Brown-out detect/reset, POR, PWM, and WDT peripherals, with an 8-channel 10-bit A/D converter.
- 1.8 V to 5.5 V supply range, internal oscillator, and -40°C to +85°C (TA) operating temperature.
- Surface-mount 64-QFN (9x9) package with 64-VFQFN exposed pad.
Applications
- Embedded control in general-purpose electronic systems using the 54 I/O pins and serial communication interfaces.
- Sensor data acquisition and measurement subsystems using the 8-channel 10-bit A/D converter.
- Peripheral expansion or memory-mapped device interfacing through the EBI/EMI bus.
- Control-signal generation using PWM outputs for external driver circuits.
- Mixed-voltage embedded designs operating from 1.8 V to 5.5 V supplies.
Design & Procurement Notes
For system design, verify that the 1.8 V to 5.5 V supply range matches the selected rail and that the 64-QFN (9x9) exposed-pad footprint is compatible with the PCB assembly process. The internal oscillator can reduce external clock circuitry, while the EBI/EMI, I2C, SPI, and UART/USART interfaces allow external peripherals to be selected based on bus type and protocol. The 128 KB FLASH, 8K x 8 RAM, and 4K x 8 EEPROM define the available code and data storage budget. The -40°C to +85°C (TA) operating range and 54 I/O pins should be considered during enclosure, thermal, and interface planning.
