OL2385 Industrial RF transceiver Rev. 2.0 24 June 2021 Product data sheet COMPANY PUBLIC 1 General information 1.1 General description The device is a fully integrated single-chip transceiver intended for use in an industrial environment. The device incorporates several commonly used building blocks including a crystal stabilized oscillator, a fractional-N-based phase-locked loop (PLL) for accurate frequency selection in both TX and RX, Low Noise Amplifier (LNA), attenuator for Automatic Gain Control (AGC), I/Q down-mixer and two high-resolution Analog to Digital Converters (ADC). The conversion into the digital domain is done in an early phase, enabling a software defined radio like approach. By transforming signals in the digital domain in an early phase, one highly configurable RX channel is available including channel mixer, channel filter, ASK/FSK demodulator, clock-data recovery, bit processor and a microcontroller memory interface (DMA) allowing the microcontroller to complete the data handling and handshaking. The device has an embedded RISC microcontroller optimized for high performance and low power as well as an EROM for customer applications. The device also includes a medium power UHF transmit system with a high dynamic range of - 35 to +14 dBm which makes it ideal for the use in narrowband communication systems. The TX system allows transmission with data rates up to 400 kbit/s NRZ. Power ramping and splatter avoidance filters are included to ensure that the transmit spectrum fulfills all the common standards in Europe, USA, and Asia. The phase noise of the transmitter supports ARIB operation. The device includes a series of timers to allow for autonomous polling and wake-up applications. The TX and RX data buffers are located in the RAM with autonomous direct memory access (DMA), reducing the real-time overhead for the accompanying microcontroller. The device can be interfaced via SPI, UART, or LIN protocol compatible UART. Simplified programming of the device is facilitated by the HAL (Hardware Abstraction Layer). The transceiver is configured to operate with low active and standby power consumption, ideal for battery powered applications.NXP Semiconductors OL2385 Industrial RF transceiver 2 Features and benefits Single IC for worldwide usage in bands between 160 MHz and 960 MHz Wide dynamic range with AGC to achieve excellent blocking performance I/Q down conversion with digital IF processing and automatic gain compensation Integrated I/Q phase and amplitude mismatch compensation Receiver path with 2 multiplexed antenna inputs enables different antenna matching Advanced signal monitoring and data management for fast and reliable signal detection and processing High dynamic range RSSI measurement Programmable PA with digitally controlled power ramping and shaping Operation up to 400 kbit/s 4FSK for high data rate applications RX and TX data buffer in RAM with independent DMA channels Integrated temperature sensor for crystal temperature drift compensation Support of high accuracy external temperature sensor for ARIB systems Integrated 16-bit extended micro RISC kernel for system on chip solutions with up to 32 kByte EROM 10 independent DMA channels for powerful data transfer and configuration Integrated copy machine for fast data transfer Coprocessor for bit manipulation and code redundancy cycle calculation (CRC) Several timers for firmware development including 3 general purpose timers, 3 RX channel timers, low power mode polling timer and watch dog timer Clock driver for micro controller crystal sharing Controlled via SPI, UART, LIN compatible UART 10 bit ADC sensor interface with up to 100kSps sampling rate Tool chain (compiler, assembler, linker, debugger) with in circuit debug capability API available to simplify custom firmware development IREC evaluation and demonstration kit available for basic RF operation Remote control protocol (RCP) to operate RF without custom firmware via SPI/UART OL2385 All information provided in this document is subject to legal disclaimers.
