Product details
Overview
OL2385AHN/001B0Y from NXP Semiconductors is a fully integrated industrial UHF RF transceiver IC supporting 158–960 MHz carrier frequencies, featuring an embedded 16-bit RISC microcontroller, fractional-N PLL, I/Q down-conversion, and programmable +14 dBm TX output. It delivers -124 dBm FSK sensitivity at 10 kHz bandwidth and operates with 700 nA power-down current for battery-powered smart metering and LPWAN applications.
For engineers reviewing the OL2385AHN/001B0Y datasheet, OL2385AHN/001B0Y pinout, OL2385AHN/001B0Y application, or OL2385AHN/001B0Y equivalent, this page provides verified technical context, validated HVQFN48 pin mapping, real-world use-value per application, and two confirmed alternative transceivers with documented functional trade-offs.
Technical Context
The OL2385AHN/001B0Y implements a low-IF receiver architecture with sigma-delta ADCs, integrated I/Q phase/amplitude mismatch compensation, and dual-antenna RX input multiplexing. Its fractional-N PLL supports 400 kbit/s 4FSK modulation with digitally controlled power ramping and splatter-avoidance filtering compliant with ARIB, ETSI, and FCC standards.
Transmit path uses a switchable +14 dBm / 0 dBm PA with 0.25 dB step power control; receive path includes 18-step RF and 15-step mixer attenuators under AGC, high-accuracy RSSI (120 dB dynamic range), and autonomous DMA-managed RX/TX buffers. The embedded microcontroller runs customer firmware from 32 kB EROM and interfaces via SPI, UART, or LIN-compatible UART.

Equivalent & Alternatives
The following parts are listed as comparable options for similar UHF transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SX1276IMLTRT | No embedded MCU; LoRa modulation only; 127–1020 MHz; +20 dBm max output | Requires external host MCU and LoRaWAN stack; better for long-range (>15 km) but less flexible protocol support | Select when LoRaWAN compliance and maximum range outweigh need for integrated firmware execution. |
| CC1312R1F3RGZR | ARM Cortex-M4F MCU; 320 kB Flash; 80 kB RAM; Sub-1 GHz + 2.4 GHz dual-band; +20 dBm | Higher BOM cost and power; supports TI-RTOS and multiple protocols (BLE, IEEE 802.15.4g) out-of-box | Select when multi-protocol flexibility, larger code space, and BLE coexistence are required over ultra-low-power optimization. |
Compared with SX1276IMLTRT and CC1312R1F3RGZR, OL2385AHN/001B0Y offers lower system-level power (700 nA vs. >1 µA standby), tighter integration (32 kB EROM + RISC core vs. external flash + ARM), and superior narrowband FSK performance (-124 dBm vs. -120 dBm), making it optimal for cost-sensitive, battery-constrained industrial telemetry.

FAQ
What is the primary function of the OL2385AHN/001B0Y in a wireless system?
The OL2385AHN/001B0Y serves as a complete UHF transceiver SoC, integrating RF front-end, fractional-N PLL, sigma-delta ADCs, 16-bit RISC microcontroller, and 32 kB EROM. It handles all physical layer functions-including modulation/demodulation, AGC, RSSI measurement, and packet framing-enabling standalone wireless nodes without external processors or memory. Its architecture supports both proprietary and standardized protocols like SigFox out of the box.
Does the OL2385AHN/001B0Y support both ASK and FSK modulation schemes?
Yes, the OL2385AHN/001B0Y natively supports ASK/OOK and FSK (including 4FSK) modulation. It achieves 400 kbit/s NRZ data rates in FSK mode using direct PLL modulation, and provides programmable PA ramping and splatter filters to meet spectral mask requirements for EN 300 220 and FCC Part 15. ASK sensitivity is specified at -123 dBm @ 10 kHz BW, while FSK reaches -124 dBm under identical conditions.
How does the OL2385AHN/001B0Y manage power consumption in battery-operated devices?
The OL2385AHN/001B0Y achieves ultra-low power operation through multiple mechanisms: 700 nA power-down current, autonomous polling timers, hardware-accelerated DMA transfers that minimize CPU wake-ups, and configurable supply domains (VDD_PA, VDD_RF, VDD_DIG) that can be powered independently. In active RX mode at 10 kHz bandwidth, supply current is 11 mA; in TX at 0 dBm, it draws 9 mA-enabling multi-year operation on coin-cell batteries in intermittent telemetry applications.
What interface options are available to configure and control the OL2385AHN/001B0Y?
The OL2385AHN/001B0Y supports SPI, UART, and LIN-compatible UART for host communication. It also implements the Remote Control Protocol (RCP), allowing full RF configuration-including frequency, modulation, power level, and packet format-via standard SPI/UART commands without custom firmware. Debug access is provided through MSDA/MSCL pins supporting in-circuit debugging with NXP's toolchain.
Is the OL2385AHN/001B0Y pin-compatible with other variants in the OL2385 family?
Yes, OL2385AHN/001B0Y shares the same HVQFN48 package (SOT619-13), pinout, and electrical characteristics with other OL2385AHN variants (e.g., /00100, /001A1, /001A2). Differences are limited to pre-flashed firmware content (SigFox stack vs. generic) and marking codes-not hardware or pin functionality. This ensures PCB design reuse across firmware-defined SKUs.
