The MG2475AZZ-F340C(hereinafter called “MG2475”) is a true 2.4 GHz system-on-chip (SOC) designed for low-power and low-cost applications based on industry standards, IEEE802.15.4 and RF4CE. Some special features and peripherals such as peripherals DMA, memory and I/O retention under the power down modes, etc are added to achieve both enhanced performance and low-power. MG2475 uses an ISM band of 2.4 ~ 2.48 GHz. In addition to the standard 250Kbps data-rate specified in IEEE802.15.4, enhanced high data-rate mode (1Mbps) with channel coding is supported. MG2475 combines an advanced RF transceiver with an industry-standard enhanced 8051 MCU, a baseband PHY, a MAC with AES-128 HW engine, an in-system programmable 64KB flash memory, a 7-KB RAM, and many other application-specific peripherals. For voice applications, the voice encoder/decoder of ADPCM and μ/a-law are embedded. MG2475 fits best for low-cost and low-power RF4CE remote control applications.
