Product details
Overview
OL2385AHN/001A2Y from NXP Semiconductors is a fully integrated industrial UHF RF transceiver IC with embedded RISC microcontroller, supporting 158–960 MHz operation, −124 dBm FSK sensitivity at 10 kHz BW, +14 dBm TX output, and 400 kbit/s NRZ data rate. It enables battery-powered narrowband systems including SigFox and smart metering.
For engineers reviewing the OL2385AHN/001A2Y datasheet, OL2385AHN/001A2Y pinout, OL2385AHN/001A2Y application, or OL2385AHN/001A2Y equivalent, key selection criteria include its dual-antenna RX input support, integrated AGC with 18×2 dB RF attenuation steps, HVQFN48 package with wettable flanks, and preflashed SigFox software stack in this variant.
Technical Context
The OL2385AHN/001A2Y implements a fractional-N PLL-based local oscillator for precise frequency synthesis in both TX and RX paths, enabling ARIB-compliant phase noise performance (−108 dBc/Hz @ 100 kHz offset at 925 MHz). Its I/Q down-conversion architecture includes on-chip amplitude/phase mismatch compensation and early digital conversion via sigma-delta ADCs.
Receiver signal processing occurs entirely in the digital domain post-ADC, featuring channel filtering, ASK/FSK demodulation, clock-data recovery, and bit processing - all managed by an autonomous DMA interface to external microcontrollers. The embedded 16-bit RISC core (32 kB EROM, 7 kB RAM) executes customer firmware and supports remote control protocol (RCP) operation without custom code.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| UHF Carrier Frequency | 158–960 MHz: Enables global sub-GHz ISM band operation across EU (868 MHz), US (915 MHz), and Asia (433/925 MHz). |
| TX Output Power | +14 dBm max: Supports long-range narrowband links; digitally controlled in 0.25 dB steps for precise power ramping and splatter suppression. |
| RX Sensitivity | −124 dBm @ FSK, 10 kHz BW: Delivers high link budget for low-duty-cycle sensor networks and battery-operated endpoints. |
| Data Rate | Up to 400 kbit/s NRZ: Meets high-throughput requirements for industrial telemetry and secure remote control. |
| Supply Voltage | 1.9–5.5 V: Allows direct single-cell Li-ion (3.6–1.9 V) or regulated 3.3/5 V operation without external regulators. |
| Power Down Current | 700 nA: Enables multi-year battery life in wake-up polling applications using integrated low-power timers. |
| Phase Noise | −109 dBc/Hz @ 100 kHz offset (868 MHz): Ensures compliance with ETSI EN 300 220 and ARIB STD-T67 spectral masks. |
| ADC Resolution | Sigma-delta 1-bit oversampled: Provides >120 dB RSSI dynamic range with fast auto-calibration (<1 µs). |
Pinout & Package
HVQFN48 package (7 × 7 × 0.85 mm, 0.5 mm pitch, wettable flanks); exposed die pad connected to GND for thermal and electrical integrity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Does OL2385AHN/001A2Y support external crystal oscillators?
Yes, OL2385AHN/001A2Y supports external crystal oscillators via XTAL_P (pin 16) and XTAL_N (pin 14), with dedicated VDD_XO (pin 13) and GND_XO (pin 15) supply domains. The device integrates crystal temperature drift compensation using its on-die temperature sensor and optionally supports high-accuracy external sensors for ARIB-compliant frequency stability across −40°C to +85°C.
How does the TRX switch in OL2385AHN/001A2Y simplify RF front-end design?
The OL2385AHN/001A2Y integrates a fully featured TRX switch with TRXSWITCH_RX (pin 3), TRXSWITCH_TX (pin 7), and TRXSWITCH_ANT (pin 5) terminals - eliminating need for discrete RF switches or PIN diodes. This reduces PCB area, insertion loss, and matching complexity while providing 50 Ω paths and >40 dB isolation between TX and RX paths in typical industrial layouts.
Can OL2385AHN/001A2Y operate from a single lithium coin cell?
Yes, OL2385AHN/001A2Y supports direct operation from a single primary lithium cell (1.9–3.6 V) without external regulators. Its wide 1.9–5.5 V supply range, 700 nA power-down current, and autonomous polling timers allow multi-year battery life in applications like wireless sensors and remote controls - with VDD_IO (pin 31) and VDD_DIG (pin 23) powered directly from the cell.
