SE8R01

1 Introduction

The SE8R01 is a single chip 2.4GHz transceiver with an embedded baseband protocol engine, suitable for ultralow power wireless

applications. The SE8R01 is designed for operation in the world wide ISM frequency band at 2.400 - 2.4835GHz.

To design a radio system with the SE8R01, you simply need an MCU (microcontroller) and a few external passive components.

You can operate and configure the SE8R01 through a Serial Peripheral Interface (SPI). The register mAp, which is accessible through

the SPI, contains all configuration registers in the SE8R01 and is accessible in all operation modes of the chip.

The embedded baseband protocol engine is based on packet communication and supports various modes from mAnuAl operation to

advanced autonomous protocol operation. Internal FIFOs ensure a smooth data flow between the radio front end and the system’s

MCU. Protocol engine reduces system cost by handling all the high speed link layer operations.

The radio front end uses GFSK modulation. It has user configurable parameters like frequency channel, output power and air data rate.

SE8R01 supports an air data rate of 500kbps, 1Mbps and 2Mbps. The high air data rates combined with two power saving modes make

the SE8R01 very suitable for ultralow power designs.

The addition of internal filtering to SE8R01 has improved the mArgins for meeting RF regulatory standards.

Internal voltage regulators ensure a high Power Supply Rejection Ratio (PSRR) and a wide power supply range.
