2990
max2990英文文挡 The MAX2990 power line communication (PLC) baseband modem delivers a cost-effective, reliable, halfduplex asynchronous data communication over AC power lines at speeds up to 100kbps. The MAX2990 is a highly integrated system-on-chip (SoC) that combines the physical (PHY) and media access control (MAC) layers using Maxim’s 16-bit MAXQ microcontroller core. The MAX2990 utilizes OFDM modulation techniques to enable robust data communication using the same electrical network that supplies power to all other devices on the network. The MAX2990 includes the MAXQ microcontroller core. The MAXQ is a 16-bit RISC microcontroller with 32kB flash memory, 5.12kB of ROM, and 8kB SRAM, of which 4kB that can be simultaneously accessed by the MCU and the PHY. The MAX2990 is integrated with modules for serial communication (SPI™, I2C, UART) and a real-time clock (RTC) for time stamping, in addition to standard blocks such as timers, GPIO, and external interrupts.
