Functional Description

PRoC LPstar devices are integrated radio and microcontroller functions in the same package to provide a dual role single-chip solution.

Communication between the microcontroller and the radio is via the SPI interface between both functions.

Features

■ Radio System-on-Chip, with built-in 8-bit MCU in a single device.

■ Operates in the unlicensed worldwide Industrial, Scientific, and Medical (ISM) band (2.400 GHz to 2.483 GHz).

■ On Air compatible with second generation radio WirelessUSB? LP and PRoC LP.

■ Pin-to-pin compatible with PRoC LP except the pin 31 and pin 37.

Intelligent

■ M8C based 8-bit CPU, optimized for human interface devices (HID) applications

■ 256 bytes of SRAM

■ 8 Kbytes of flash memory with EEPROM emulation

■ In-System reprogrammable through D+/D– pins
