ATMEGA32L-8MU

ATMEL  ATMEGA32L-8MU  微控制器, 8位, 低功率高性能, ATmega, 8 MHz, 32 KB, 2 KB, 44 引脚, VQFN

The is a high-performance, low-power 8-bit AVR RISC-based Microcontroller combines 32kB of programmable flash memory, 2kB SRAM, 1kB EEPROM, an 8-channel 10-bit A/D converter and a JTAG interface for on-chip debugging. The device supports throughput of 16MIPS at 16MHz and operates between 4.5 to 5.5V. By executing instructions in a single clock cycle, the device achieves throughputs approaching 1MIPS per MHz, balancing power consumption and processing speed. The device is manufactured using Atmel"s high density nonvolatile memory technology. The on-chip ISP flash allows the program memory to be reprogrammed in-system through an SPI serial interface, by a conventional nonvolatile memory programmer, or by an on-chip boot program running on the AVR core. The boot program can use any interface to download the application program in the application flash memory.
