Port speeds span 1GbE to 400GbE across the SN3000 series platform family, giving fabric designers flexibility in leaf/spine blocking ratios. Typical applications include high-density 100G/200G leaf-spine data center fabrics, super-spine aggregation layers, cloud and enterprise top-of-rack aggregation, and storage network backends where 200GbE uplinks reduce oversubscription. When deploying, verify rack airflow direction compatibility (C2P versus P2C variants exist in the same family) and confirm AC power feed redundancy before installation.

NEO-M8T-0 - Concurrent GNSS Timing Module, -167dBm | u-blox
The u-blox NEO-M8T-0 is a concurrent GNSS timing receiver module built on the u-blox M8 platform, supplied in a compact 12.0 x 16.0 mm LCC surface-mount form factor. It supports simultaneous reception of four global navigation satellite systems - GPS, GLONASS, Galileo, and BeiDou - plus QZSS, and provides tracking sensitivity down to -167 dBm together with an industry-leading acquisition sensitivity of -148 dBm for cold starts. What is a GNSS timing module? A GNSS (Global Navigation Satellite System) timing module is a satellite-receiver subsystem that derives precise frequency, phase, and time-of-day information from atomic-clock references aboard navigation satellites. Within the broader power-and-clock hierarchy a timing module sits alongside oscillators, RTCs, and TCXOs as the highest-accuracy time reference, sitting above standalone oscillators in stability and below PTP/NTP grandmasters in protocol richness. The timing-module category is engineered for applications where nanosecond-level pulse alignment, deterministic 1 PPS output, or raw pseudorange observables are required. The NEO-M8T-0 delivers two key timing features that distinguish it from navigation-grade modules: a configurable timepulse (1 PPS) output with sub-25 ns jitter and a survey-in mode that disciplines the internal oscillator against GNSS-derived timing, allowing the receiver to act as a stable, disciplined clock source even when fewer than four satellites are visible. The module also provides raw carrier-phase and pseudorange data over UART, USB, SPI, and I2C (DDC) for use in research, geodesy, and timing-instrumentation applications. Power consumption is optimized for low-duty-cycle timing deployments. Typical applications include cellular base-station synchronization (e.g., 4G/LTE and 5G NR networks requiring holdover), broadcast audio and DVB-T transmitters, power-grid PMU phasor measurement units, financial timestamping servers for MiFID II compliance, and scientific instruments such as radio telescopes and particle-physics experiments. The wide operating temperature range of -40C to +85C and the standard NEO form factor (pin-compatible with NEO-M8N and other u-blox M8 modules) allow ready migration from earlier u-blox generations. When designing with this part, provide a stable primary supply between 2.7V and 3.6V, an active antenna with at least 15 dB of gain, and route the timepulse and serial lines away from switching converters. Note that the -167 dBm tracking figure gives 6 dB of margin over navigation-only modules, which is critical for timing applications where partial satellite visibility is common.

NINA-B112-04B-00 - BLE 5.0 Module, nRF52832 | u-blox
The u-blox NINA-B112-04B-00 is a stand-alone Bluetooth 5.0 low energy (BLE) transceiver module operating in the 2.4 GHz band, built on the Nordic Semiconductor nRF52832 SoC with an integrated chip antenna, delivered in a compact surface-mount NINA-B1 form factor. A Bluetooth low energy module is a complete radio subsystem that integrates the RF transceiver, microcontroller, antenna, and certified RF matching network into a single drop-in component. Within the connectivity hierarchy, it sits below full networking gateways but above bare SoCs: engineers gain a fully certified, pre-tested radio without designing a 2.4 GHz RF section, greatly reducing certification cost and time to market. Key features of the NINA-B112-04B-00 include Bluetooth v5.0 compliance with 2 Mbps PHY support, 512 kB flash memory and 64 kB RAM for application code and data, and an internal metal-optimized PIFA chip antenna providing a range of more than 300 m independent of ground plane and component placement, according to the NINA-B1 datasheet (UBX-15019243). The module supports Bluetooth mesh and up to 20 simultaneous Bluetooth connections. Technically, the module is powered by the nRF52832, whose Cortex-M4F processor executes either the pre-flashed u-blox u-connectXpress firmware (AT-command driven) or, in the open-CPU NINA-B1 variants, customer application code directly. The NINA-B112-04B carries u-connectXpress software; the -00B variant ships with open CPU firmware for native development. Typical applications include industrial sensor nodes, smart-home and IoT edge devices, asset trackers, and battery-powered medical wearables, where its low-power BLE profile and worldwide radio certifications shorten design cycles. A key design consideration is antenna keep-out: although the internal PIFA is ground-plane independent, the system integration manual requires a defined clearance area around the module to preserve the 300 m-plus range performance.

NRF9160-SICA-B1A-R7 LTE-M/NB-IoT GPS SiP Module
Nordic Semiconductor NRF9160-SICA-B1A-R7 is a low-power cellular IoT System-in-Package combining an Arm Cortex-M33 processor, LTE-M/NB-IoT modem, RF front end, GPS support, 1 MB Flash, and 256 KB RAM in a 127-PowerTFLGA module. The integrated modem supports 3GPP LTE Release 13 Cat-M1 and Cat-NB1 and 3GPP LTE Release 14 Cat-NB1 and Cat-NB2, while the RF section covers approximately 700 MHz to 2.2 GHz. The nRF9160 is a highly integrated cellular IoT module rather than a conventional discrete transceiver. Its processor, modem, radio front end, security features, memory, and power-management functions are combined in one package, simplifying cellular product development. The module is designed for low-power single-device designs and supports cellular connectivity alongside integrated location tracking. Key features include an Arm Cortex-M33 application processor, advanced hardware security, integrated GPS, 1 MB of Flash memory, 256 KB of RAM, and a complete cellular modem. The architecture allows embedded firmware, networking, application processing, and radio connectivity to be handled in a compact module rather than across several discrete components. The nRF9160 supports both LTE-M and NB-IoT, including LTE Release 13 and Release 14 categories listed in the manufacturer material. This broad standards support is useful for products that must operate across different cellular deployments. The integrated RF front end and modem reduce the amount of external RF integration required compared with a discrete cellular design. Typical applications include cellular IoT sensors, asset trackers, smart meters, industrial monitoring equipment, connected logistics devices, and GPS-enabled remote telemetry products. The integrated GPS capability is particularly useful when an application needs location data without adding a separate GPS receiver. Designers should preserve the module’s recommended power, decoupling, antenna, and RF layout practices. Cellular designs are sensitive to grounding, antenna routing, transmission power, regulatory requirements, and power-supply stability. Review the manufacturer product specification and ordering information before finalizing PCB layout or changing the hardware revision. This page synthesizes the verified distributor descriptions, manufacturer datasheet references, packaging information, application guidance, and drop-in cross-reference evidence for NRF9160-SICA-B1A-R7. Pricing, detailed electrical limits, pin-level data, and certification status must be confirmed against the latest manufacturer documentation and distributor records.
NTAG213 - NFC Forum Type 2 Tag, 144B User Memory | NXP
The NXP Semiconductors NTAG213 is a NFC Forum Type 2 Tag compliant contactless IC that operates at 13.56 MHz and exposes 144 bytes of user-accessible memory. It is fully compliant with NFC Forum Type 2 Tag and ISO/IEC 14443 Type A specifications, and is housed in standard wafer-level packages (e.g., SOT-23-equivalent die or bare-die formats used on inlays and tags). As an NFC Type 2 tag, the NTAG213 belongs to the broader family of passive contactless memory tags that harvest operating energy from the RF field of an NFC reader or smartphone. The NTAG21x family (NTAG213/215/216) is NXP's mainstream product line for NFC tags; within that family, NTAG213 is the lowest-memory variant. Type 2 Tags sit below NFC Type 4 Tags (ISO/IEC 14443-4 compliant) in the NFC Forum tag hierarchy and are optimized for simple, low-cost, high-volume tap-and-read use cases rather than secure transactions. Key features of the NTAG213 include a 7-byte unique identifier (UID), a 32-bit password-based protection mechanism with password attempt counter, a 24-bit one-way programmable (OTP) memory area, an ECC-based originality signature for anti-cloning support, a built-in NFC counter (NTAG213 also exposes the ASCII mirror and UID ASCII mirror pages), and a true anti-collision loop that allows multiple tags to be inventoried in the field simultaneously. Read range is typically up to 10 cm depending on antenna geometry. Technically, the NTAG213 implements a half-duplex, 106 kbit/s data rate over ISO/IEC 14443 Type A modulation. The internal memory is organized into user memory (144 bytes) plus configuration pages, with write endurance rated for 100,000 cycles per page and data retention of 10 years per the NXP datasheet. The IC operates without any external power source: the analog front end and on-chip rectifier derive all operating current from the reader's RF field. Typical applications include smart out-of-home and print media advertising, Bluetooth pairing / Wi-Fi hand-off companion tags (NFC Forum NDEF handover), product authentication labels via the originality signature, NFC shelf labels in retail, business card / SoLoMo tap-to-action tags, and game figure integration (NTAG213 is used in many Bluetooth-paired toys and is one of the memory options for NFC Forum NDEF-based consumer uses). When designing with NTAG213, observe the antenna matching guidance in the NXP application notes: a recommended etched or printed coil antenna of roughly 35 mm x 35 mm to 45 mm x 45 mm delivers the typical 5-10 cm read range on a mobile phone reader, and a tuning capacitor in the 15-25 pF range compensates the loop inductance. Keep sufficient clear space around the antenna, and avoid placing the tag directly on metal surfaces without a ferrite shield. This page consolidates distributor pricing, drop-in alternatives, and practical antenna/design notes not assembled in the manufacturer datasheet alone.
NTAG215 - 504B NFC Type 2 Tag IC, ISO/IEC 14443A | NXP
The NXP Semiconductors NTAG215 is an NFC Forum Type 2 Tag compliant IC with 504 bytes of usable user memory (126 pages of 4 bytes), 7-byte UID, and a 32-bit one-way counter, fully compliant to ISO/IEC 14443 Type A. It operates at 13.56 MHz and is delivered in wafer-level packages including the standard NTAG215 die form used inside contactless smart cards, tags, and labels. An NFC (Near Field Communication) tag IC is a passive, contactless memory device that harvests operating energy from the RF field of an NFC reader and exposes its stored data over the air using a standardized protocol. NFC Forum Type 2 Tags are based on ISO/IEC 14443 Type A and are the most widely supported tag type in consumer NFC devices (smartphones, tablets). In the broader hierarchy, the NTAG215 belongs to the family of contactless memory ICs -> RFID transponders -> NFC/RFID semiconductors -> wireless connectivity ICs. Its Type 2 compliance guarantees interoperability with virtually every modern NFC reader. Key features include 504 bytes of user-accessible EEPROM organized as 126 pages, a factory-programmed 7-byte unique identifier (UID), a 32-bit one-way counter for tamper detection or tap counting, NFC Forum Type 2 Tag and ISO/IEC 14443 Type A compliance, 106 kbps data rate, and built-in password protection with full memory read/write protection. Typical read range is up to 10 cm depending on antenna geometry, and operating temperature spans -25C to +70C for consumer variants. The NTAG215 is the middle-memory sibling in the NTAG21x family, positioned between the smaller NTAG213 (144 bytes) and the larger NTAG216 (888 bytes). All three share the same command set, UID length, counter, and password feature, making them software-compatible. The NTAG215's 504-byte capacity was chosen by NXP and Nintendo to exactly accommodate Amiibo figures, which is why the part is the de facto standard for NFC gaming collectibles and many consumer IoT pairing tags. Typical applications include Nintendo Amiibo figures, gaming collectibles, product authentication and anti-counterfeit labels, Bluetooth/Wi-Fi pairing NFC tags, smart posters and out-of-home advertising, vCard/business card sharing, mobile companion tags, and inventory/asset tracking where medium-capacity Type 2 memory is sufficient. When designing with the NTAG215, ensure the antenna is matched to 13.56 MHz and the contactless coupling area supports ISO/IEC 14443 Type A communication. The password feature must be enabled by writing the relevant configuration pages; failure to lock memory leaves the tag open to unauthorized rewrite. For Amiibo compatibility, use only NTAG215 (not NTAG216 or NTAG213) at the exact page count, since Amiibo NDEF payloads are sized for 504 bytes. This page synthesizes cross-distributor pricing, drop-in and same-family alternatives, and practical design notes for embedding NTAG215 into cards, tags, and labels not found in the bare manufacturer datasheet.
OM-O2P - Omega2+ WiFi IoT Module, 2.4GHz, 580MHz | Onion
The Onion Corporation OM-O2P is the Omega2+ System-On-Module (SOM), a compact Linux-based IoT computer integrating a 580 MHz MIPS 24KEc SoC, 128 MB DDR2 memory, 32 MB on-board flash, and a 2.4 GHz 802.11 b/g/n WiFi transceiver in a through-hole module form factor designed for breadboard and docking-station prototyping. What is a System-On-Module? A System-On-Module (SOM) is a small, self-contained computing module that integrates a microprocessor, memory, wireless radios, and power management onto a single PCB, exposing interfaces through pin headers. SOMs sit in the hierarchy between a microcontroller (no OS, single-purpose) and a single-board computer (full I/O on one board). The Omega2+ family targets the IoT edge node category, offering Linux programmability in a footprint smaller than a credit card, suitable for connected-device prototyping. Key features include 802.11 b/g/n WiFi with on-board PCB antenna, hardware cryptographic support, hardware-accelerated microSD slot accepting SDXC cards up to 2 TB at up to 300 MB/s, and 15 GPIO pins for peripheral integration. The OM-O2P draws approximately 260 mA at 3.3 V under typical WiFi-active load, supports firmware updates over the air (FOTA), and exposes USB 2.0, I2C, I2S, SPI, and UART interfaces through the 2x15 2.54 mm pin header. Technically, the OM-O2P is built around the MediaTek MT7688AN MIPS-based WiFi SoC, which combines a 580 MHz MIPS 24KEc CPU core with an integrated 802.11n MAC/baseband/radio. This single-chip architecture keeps the BOM compact and BOM cost low while providing enough compute for lightweight Linux tasks, MQTT clients, and on-device scripting. The 128 MB DDR2 RAM is double what the smaller Omega2 (OM-O2) ships with, allowing larger application workloads. Typical applications include home automation gateways, WiFi-connected sensor nodes, IP-camera prototypes, smart agriculture controllers, and educational Linux-on-SoC platforms. Designers frequently dock the OM-O2P onto the Onion Expansion Dock (OP-EA) or the Arduino-compatible Power Dock (OP-PA) to access Arduino-shield expansion. When designing with this module, verify that your 3.3 V regulator can supply at least 500 mA peak for WiFi TX bursts, and place a local 10 uF decoupling capacitor near the VIN pin. The through-hole header footprint makes the module hand-solderable and breadboard-friendly without requiring reflow equipment. This page synthesizes distributor pricing, real drop-in alternatives within the Omega2 family, and practical docking-station design notes not found in the manufacturer datasheet alone.
OM5577/PN7120ARDM - PN7120 NFC Controller Arduino Dev Kit | NXP
The NXP Semiconductors OM5577/PN7120ARDM is an Arduino-compatible Single Board Computer (SBC) development kit built around the PN7120 NFC controller, providing full NFC Forum compliance for Reader, P2P, and Card Emulation modes. The kit integrates the PN7120S transceiver IC on a compact PCB with an Arduino-shield form factor, exposing the controller's I2C/SPI host interface, integrated firmware, and NCI (NFC Controller Interface) protocol stack. Per NXP's product page, the OM5577 family simplifies NFC integration on Arduino-compatible platforms, including LPCXpresso, Kinetis, and many i.MX boards. An NFC (Near Field Communication) development kit is a hardware platform that lets engineers evaluate and prototype NFC reader/writer functionality at 13.56 MHz without designing RF antennas or low-level driver code from scratch. Within the broader embedded ecosystem hierarchy, NFC controllers fall under the wireless connectivity category (NFC -> RFID HF -> short-range wireless -> RF/IF), and the PN7120 belongs to NXP's Plug-and-Play NFC controller family designed for OS-driven (Linux, Android, Windows) host environments. The OM5577/PN7120ARDM variant specifically targets Arduino-header platforms, distinguishing it from the OM5577/PN7120RPI (Raspberry Pi) and OM5577/PN7120BBB (BeagleBone Black) variants in the same family. Key features include full NFC Forum Type 1/2/3/4/5 tag support, ISO/IEC 14443 Type A and B, ISO/IEC 15693, FeliCa, and ISO/IEC 18092 (NFCIP-1) peer-to-peer compliance. The kit provides pre-integrated RF matching, an onboard antenna, and a standard Arduino Uno R3 shield pinout. Power is supplied through the Arduino headers (5 V and 3.3 V rails), and the PN7120 communicates with the host MCU via I2C at up to 3.4 Mb/s. Integrated firmware handles modulation, framing, anti-collision, and crypto acceleration, leaving the host application to issue NCI commands through the supplied NXP Linux driver or Windows DLL. Typical applications include contactless payment terminals, access control readers, Bluetooth pairing via NFC tap, electronic shelf labels, industrial tag readers, and IoT provisioning where a tap gesture is more ergonomic than typing credentials. The wide protocol coverage and pre-certified RF section reduce EMC qualification time versus discrete NFC designs.
OZD PROFI 12M G11 - PROFIBUS Fiber Optic Repeater | Hirschmann
The Hirschmann OZD PROFI 12M G11 (order number 942 148-001, formerly 943 727-221) is a PROFIBUS fiber-optic repeater that converts electrical RS-485 PROFIBUS signals into optical signals over quartz glass fiber and back, while also functioning as a repeater to extend bus segment length. It provides 1 optical port (2 x BFOC 2.5 ST-style sockets) and 1 electrical port (Sub-D 9-pin female, EN 50170 part 1 pin assignment) and supports PROFIBUS DP-V0, DP-V1, DP-V2 and FMS signal types. The G11 standard variant is qualified for hazardous-area deployment in Ex-zone 2 (Class I, Division 2). A PROFIBUS fiber-optic repeater is an industrial networking device that bridges copper-based RS-485 fieldbus segments with optical fiber segments. Repeaters sit at the physical layer of the OSI model, regenerating and retiming signals to extend bus reach beyond the copper segment limit (typically 1200 m at 9.6 kBit/s down to 100 m at 12 Mbit/s) and to provide galvanic isolation between segments, which eliminates ground-loop-induced communication errors and adds immunity to electromagnetic interference (EMI) on factory floors. Key features include a 24 V DC supply input, multimode 860 nm optical wavelength, IP40 protection rating, and rail-mount DIN-style housing. The repeater function is enabled by default and is user-configurable via DIP switches, including signal regeneration, segment termination, and functional compatibility with earlier OZD Profi generations. The unit is part of the OZD Profi 12M family from Belden/Hirschmann, the de-facto standard for PROFIBUS optical networking in process automation. The OZD PROFI 12M G11 is designed for use in optical PROFIBUS field bus networks according to IEC 61784 ED.1:2002 CPF3/1. Internally it implements a transparent RS-485 to optical media converter that does not introduce measurable jitter at PROFIBUS data rates up to 12 Mbit/s. The two ST (BFOC 2.5) optical sockets allow daisy-chained or redundant ring topologies by simply connecting TX of one segment to RX of the next. Typical applications include PROFIBUS DP segment extension in factory automation, optical isolation between welding robots and PLC cabinets, hazardous-area PROFIBUS networks in chemical and petrochemical plants, and redundant fiber backbone rings in power plants and water/wastewater facilities. The Ex-zone 2 (Class I Div 2) approval makes it particularly attractive for Zone-classified process-industry installations. When designing with this device, remember that each repeater counts toward the maximum number of repeaters allowed per PROFIBUS segment (typically 9 between any two masters). Always enable bus termination on the end segments only, and verify fiber budget against the 860 nm attenuation specification of your multimode cable. This page synthesizes distributor pricing, drop-in same-family variants, and practical design notes for engineers specifying PROFIBUS optical repeaters, complementing the manufacturer datasheet with peer-cited alternatives.
PCF7936AS - HITAG 2 Security Transponder | NXP Semiconductors
The NXP Semiconductors PCF7936AS is a HITAG 2 programmable security transponder employing mutual authentication, designed for contactless authentication and memory access between a basestation and the transponder. Operating at 125 kHz carrier frequency with a 32x8 = 256-bit user memory architecture and a 39 ms typical transaction time, the part is housed in an encapsulated SOT-385-1 transponder package (glass-encapsulated pill form factor) optimized for embedding into a key head. What is a security transponder? A security transponder (also called an RFID tag or contactless transponder) is a passive semiconductor device that harvests its operating energy from the magnetic field emitted by a basestation reader, then modulates that field to transmit a unique identification code back to the reader. Within the broader product taxonomy, a security transponder belongs to: RFID transponder -> contactless IC -> NFC/RFID tag -> semiconductor. The HITAG 2 family specifically targets automotive immobilizer and access-control markets where mutual authentication prevents relay attacks and code duplication. Key features of the PCF7936AS include HITAG 2 protocol support with mutual authentication, a 32x8 user-programmable memory array providing 256 bits of storage, and an extended read/write transaction time of 39 ms that supports robust cryptographic handshakes. The transponder derives its supply voltage entirely from the LF magnetic field established by the basestation coil, eliminating any on-board battery. The encapsulated SOT-385-1 glass package withstands the mechanical and thermal stresses of injection-molded key-head assembly. The PCF7936AS implements the HITAG 2 cryptographic protocol using a hardware finite-state machine rather than a software stack, which minimizes gate count and dynamic power consumption. Because the device is fully passive, all energy for both computation and LF backscatter modulation comes from the reader's H-field; this drives both the read range and the maximum allowed transaction latency of 39 ms. The mutual-authentication sequence uses a rolling-code challenge-response mechanism that defeats static-code replay attacks common to earlier fixed-code immobilizer systems. Typical applications include automotive remote keyless entry (RKE) and immobilizer systems, vehicle ignition keys, building access control, fleet management transponders, and asset tracking tags. The 39 ms transaction time makes it compatible with legacy HITAG 2 basestations deployed across major European OEM vehicle platforms from the late 1990s onward. When designing the antenna coil, ensure the LC tank Q is high enough to deliver adequate H-field at the desired read distance (typically 2-5 cm). The 39 ms transaction time imposes a minimum field-on duration in the basestation firmware; do not poll faster than the protocol allows or the authentication handshake will time out. This page synthesizes distributor inventory, drop-in alternatives, and practical design notes not found in the manufacturer datasheet, helping sourcing engineers and immobilizer system integrators evaluate the PCF7936AS against current alternatives.
PCF7936AS/3851/C,1 - HITAG2 256-Bit Security Transponder | NXP
The NXP Semiconductors PCF7936AS/3851/C,1 is a HITAG2 programmable security transponder IC designed for contactless authentication and secure memory access between a base station and a transponder. Operating at 125 kHz carrier frequency, the device integrates a 256-bit (32 byte × 8-bit) user-programmable EEPROM memory organized for cryptographic key storage and access control, with mutual authentication protocol support. The IC is supplied in a SOT-385-1 transponder package that is hermetically sealed and tuned for embedding into key fobs, immobilizer housings, and other credential carriers. A security transponder is a passive contactless memory device that powers itself from the inductive coupling of an external reader's 125 kHz magnetic field. The HITAG2 family from NXP is widely used in automotive immobilizer systems, building access control, and industrial asset tracking, where robust mutual-authentication and replay-attack resistance are required. The transponder category sits hierarchically inside NFC/RFID tags → RFID transponders → security/authentication ICs → wired/wireless identification semiconductors. Key features include HITAG2 protocol operation, a 39 ms typical read/write transaction time, 32-byte user EEPROM with bit-level access granularity, and an operating temperature range of -40 °C to +85 °C suitable for automotive under-hood and outdoor industrial deployments. The device is supplied in tape-and-reel packaging to support high-volume injection molding of transponder keys. Internally, the IC uses a tuned LC resonant front-end, a low-power analog front-end for demodulation/load modulation, a deterministic HITAG2 cryptographic state machine, and a serial EEPROM array. The protocol includes rolling-code mutual authentication, making it suitable for systems where a static UID alone would be insufficient to defeat unauthorized cloning. Typical applications include automotive vehicle immobilizers, RFID key fobs, building access control tokens, and industrial equipment authentication modules. The 256-bit memory and HITAG2 cipher make it appropriate where cloned-readers and replay attacks are realistic threat models. Compared with 1-Wire or 13.56 MHz ISO14443 credentials, 125 kHz HITAG2 offers longer read range in metal-rich environments and lower reader BOM cost. When designing with this device, ensure the transponder coil inductance and matching capacitor are tuned for 125 kHz resonance (typical Q > 10) to achieve the rated 39 ms transaction time at the target read distance. Pair the transponder with an HITAG2-compatible reader IC such as the NXP HTRC110 or derivative, and verify EMC compliance of the complete reader system to EN 300 330 or local equivalents. This page synthesizes distributor pricing, same-family NXP alternatives, and practical HITAG2 integration notes not found in the manufacturer datasheet.
