Development Kits


The MG2460 is a 2.4GHz IEEE 802.15.4 and ZigBee compliant SoC(system-on-chip). The MG2460 includes a high performance transceiver, a hardwired MAC with AES-128 engine, an accelerated 80251 MCU with internal 128-KB flash memory and 16-KB SRAM, and application-specific peripherals. The MG2460 operates in the 2.4~2.4835 GHz ISM band, with Tx output power up to +9 dBm, Rx sensitivity of -98 dBm and excellent coexistence with 802.11 WLAN. It supports multiple data rates from 250 kbps to 2 Mbps, besides standard specific data rate of 250 kbps. In addition, it can also support channel coding for robust data communications.
