ATMEGA48-20MU (MICROCHIP)
8 Bit MCU, Будет Указано Позже
The ATMEGA48-20MU is a high-performance, low-power 8-bit AVR RISC-based Microcontroller combines 4kB ISP flash memory, 512byte SRAM, 256byte EEPROM, an 8-channel/10-bit A/D converter (TQFP and QFN/MLF) and debugWIRE for on-chip debugging. The device supports a throughput of 20MIPS at 20MHz and operates between 2.7 to 5.5V. By executing powerful 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.
