EM2420 General Description

The EM2420 is a true single-chip 2.4 GHz IEEE 802.15.4 compliant RF transceiver designed for low-power and low-voltage wireless applications. The EM2420 includes a digital direct sequence spread spectrum baseband modem and an effective datarate of 250 kbps. The EM2420 chip is only available from Ember with a licensed Ember networking stack and is targeted to approved 8-bit processors.

The EM2420 is a low-cost, highly integrated solution for robust wireless communication in the 2.4 GHz unlicensed ISM band. It complies with world-wide regulations covered by EN 300 440 (Europe), CFR47 Part 15 (US) and ARIB STD-T-66 (Japan).

The EM2420 provides extensive hardware support for packet handling, data buffering, burst transmissions, data encryption, data authentication, clear channel assessment, link quality indication and packet timing information. These features reduce the load on the host controller and allow the EM2420 to interface low-cost microcontrollers. The configuration interface and transmit / receive FIFOs of the EM2420 are accessed via a SPI interface. In a typical application, the EM2420 will be used together with a microcontroller and a few external passive components.

The EM2420 is manufactured to a 0.18 m CMOS process.
