The Texas Instruments CC115LRGPR is a value line sub-1 GHz RF transmitter supporting FSK, GFSK, and OOK modulation with up to 12 dBm output power and data rates up to 600 kbps, covering the 300-348 MHz, 387-464 MHz, and 779-928 MHz ISM/SRD frequency bands in a 20-pin VQFN (RGP) exposed-pad package rated from -40C to +85C. A sub-1 GHz RF transmitter is a single-chip wireless device that converts baseband data into a modulated RF carrier for license-free industrial, scientific, and medical (ISM) or short-range device (SRD) bands. Within the wireless connectivity hierarchy, it sits below full transceivers (which add a receive path) and above complete modules, forming the transmit half of a low-cost RF link. Texas Instruments designed the CC115L value line transmitter to pair with the CC113L value line receiver, enabling a bidirectional-capable but cost-optimized radio system. Key features include RF performance identical to the popular CC1101 RF transceiver, 12 dBm maximum output power for range-critical links, flexible FSK/GFSK/OOK modulation, and data rates up to 600 kbps. A fast wake-to-transmit latency of approximately 240 microseconds supports aggressive duty-cycling for battery-powered nodes. The device requires minimal external components: only a crystal, a few decoupling capacitors, and a simple antenna-matching network. Technically, the CC115L shares its radio architecture and register map with the CC1101, which means SmartRF Studio configuration files and RF register settings developed for CC1101 transmit chains port directly to the CC115L. The standard SPI interface (SCLK, SI, SO, CSn) connects to virtually any low-cost microcontroller, and packet-oriented data FIFOs offload the host MCU from bit-level timing. TX-only operation reduces die area and cost compared with the CC1101 transceiver. Typical applications include 433 MHz and 868/915 MHz remote controls and keyless entry, wireless alarm and security sensors, sub-1 GHz IoT sensor nodes for smart metering, and industrial telemetry where the 12 dBm output extends link range through building structures. According to Texas Instruments, the CC115L is EN 300 220 and FCC Part 15-friendly for SRD system designs. Design consideration: RF matching networks are band-specific; use TI reference designs (e.g., the 433 MHz and 868/915 MHz matching networks in the CC115L datasheet) and place the exposed ground pad on a solid ground plane with multiple vias for RF ground integrity and thermal dissipation.

Key features include 16-kV HBM ESD protection on the MDI pins, Energy Efficient Ethernet (EEE) per IEEE 802.3az, Wake-on-LAN (WoL), programmable Energy Detect power-down modes that drop link power below 10 mW, cable-length diagnostics, and a 25-MHz reference clock output. The MAC interface supports MII, RMII, and RGMII for direct connection to microcontrollers, FPGAs, ASICs, or industrial Ethernet controllers without glue logic. Industrial temperature range is -40 °C to +125 °C, suitable for factory automation, motor control, and outdoor equipment. Typical applications include industrial Ethernet fieldbus modules (EtherCAT, PROFINET, EtherNet/IP slave nodes), PLC communication ports, motor-drive control boards, building-automation gateways, and outdoor surveillance switches. The robust ESD margin and extended temperature range remove the need for external TVS protection in many designs, lowering BOM cost and improving MTBF. Design tip: route the 50 Ω differential MDI pairs with controlled 100 Ω differential impedance, keep the 25 MHz crystal within 8 mm of the XI/XO pins, and provide a ferrite bead on AVD supply pins to meet IEEE 802.3 return-loss masks. Always consult the TI datasheet for full layout and magnetics recommendations.
DP83822IFRHBT - 10/100 Ethernet PHY Transceiver | TI
The Texas Instruments DP83822IFRHBT is a robust, low-power 10/100-Mbps Ethernet Physical Layer (PHY) transceiver with fiber support and 16-kV ESD protection, housed in a 32-pin VQFN (RHB) 5x5 mm package. It supports MII, RMII, and RGMII MAC interfaces, and provides a fiber-mode output for 100BASE-FX operation. An Ethernet PHY (Physical Layer transceiver) is a mixed-signal IC that connects a Media Access Controller (MAC) to the physical copper or fiber medium. It performs 10BASE-T/100BASE-TX encoding/decoding, line driving, link training, and cable diagnostics. The DP83822 family belongs to the Ethernet transceiver category in the broader hierarchy of networking ICs > interface ICs > semiconductors. Key features include a wide operating temperature range of -40C to +85C, 50-MHz clock output, Energy Efficient Ethernet (EEE) support per IEEE 802.3az, built-in cable diagnostics, and integrated termination resistors. The 16-kV HBM ESD rating exceeds typical industrial requirements and reduces external protection component count. Architecturally, the DP83822I integrates the analog front-end, DSP-based adaptive equalizer, baseline wander correction, and a digital PLL, all controlled via the MDIO management interface. Multiple operating modes (MII, RMII, RGMII) make it compatible with virtually any modern Ethernet MAC, including those in Sitara processors, microcontrollers, and FPGAs. Typical applications include industrial Ethernet sensors, factory automation controllers, motor drives with Ethernet connectivity, building automation gateways, and fiber-to-the-node industrial links. The fiber support enables operation over longer distances and in electrically noisy environments where copper Ethernet is impractical. When designing with the DP83822IFRHBT, ensure the magnetics module is properly matched to the PHY and that the MDIO clock does not exceed 25 MHz. The 50-MHz clock output can drive a companion MAC or be disabled to save power in cost-optimized designs.

DP83869HMRGZT - 1G Ethernet PHY Transceiver | Texas Instruments
The Texas Instruments DP83869HMRGZT is a high-immunity, extended-temperature gigabit Ethernet Physical Layer (PHY) transceiver with integrated Physical Media Dependent (PMD) sublayers, supporting 10BASE-Te, 100BASE-TX, 1000BASE-T copper protocols plus 100BASE-FX and 1000BASE-X fiber protocols, housed in a 48-pin VQFN (RGZ) 7x7 mm package. It interfaces to a Media Access Controller (MAC) through a standard Reduced Gigabit Media Independent Interface (RGMII) or Serial Gigabit Media Independent Interface (SGMII). The device operates from a 1.8V, 2.5V, or 3.3V supply rail, allowing direct connection to common digital I/O voltages in industrial processors. Background knowledge: a Gigabit Ethernet PHY is the physical-layer transceiver in the OSI seven-layer model that encodes/decodes Ethernet frames to and from electrical or optical signaling on copper or fiber media. The PHY bridges the digital MAC layer to the analog line, performing line equalization, echo cancellation, clock-data recovery, and link training. In the system hierarchy, a PHY sits below the MAC, above the connector/MDI, and forms part of the broader Network Interface Card (NIC), Switch, or Industrial Ethernet Equipment architecture. The DP83869HM family belongs to the Industrial Ethernet PHY category, optimized for harsh-environment immunity rather than office-style connectivity. Key features include robust Electrostatic Discharge (ESD) protection exceeding 8 kV IEC 61000-4-2 direct-contact discharge, integrated MDI termination resistors, support for Energy-Efficient Ethernet (EEE) per IEEE 802.3az, and Time-Sensitive Networking (TSN) readiness. The device provides cable diagnostics with TDR-based fault location, programmable LED behavior for link/activity/speed status, and an MDIO management interface per IEEE 802.3 clause 22/45 for PHY register access. Technically, the DP83869HMRGZT combines mixed-signal CMOS with on-chip DSP-based adaptive equalization, baseline wander correction, and a robust PLL clock recovery loop that maintains GigE line-locked operation across Cat-5e cable lengths up to 100 m. Internal LDOs generate the analog and digital core rails from a single external supply, simplifying the BOM. The device is rated for an extended industrial temperature range of -40C to +125C, suitable for fanless, sealed enclosures. Typical applications include industrial Ethernet switches, Programmable Logic Controller (PLC) communications modules, grid infrastructure (IEC 61850-3) substation gateways, factory-automation line controllers, and ruggedized surveillance recorders. The dual copper/fiber interface also makes it appropriate for industrial protocol bridges (EtherCAT, PROFINET, EtherNet/IP) where a fiber uplink is needed for long-haul or noise-isolated segments. Design consideration: the RGMII timing skew between MAC and PHY must be tuned per the datasheet's TX/RX clock-to-data delay register settings; mis-tuned skew at 1 Gbps is the most common source of intermittent CRC errors. Use the TI USB-2-MDIO tool plus the DP83869 EVM register scripts to verify default skew values for your MAC partner before locking the PCB layout.

DP83TD510ERHBR - 10BASE-T1L Ethernet PHY, 32-VQFN | TI
The Texas Instruments DP83TD510ERHBR is an ultra-low power IEEE 802.3cg 10BASE-T1L single-pair Ethernet physical layer transceiver delivering 10 Mbps over a single twisted pair, packaged in a 32-pin VQFN (RHB) 5x5 mm footprint. It supports long cable reaches of 1200 meters at 1-V p2p swing and 1700+ meters at 2.4-V p2p swing, with ultra-low power dissipation of 45 mW in 1-V p2p mode and 99 mW in 2.4-V p2p mode. A 10BASE-T1L PHY (Physical Layer device) is a specialized Ethernet transceiver that operates over a single differential pair instead of the two or four pairs used in traditional 10/100/1000BASE-T. Defined by the IEEE 802.3cg standard, it enables Ethernet connectivity in industrial process automation, building automation, and remote sensor networks where cable reach, intrinsic safety, and EMC robustness matter more than raw bandwidth. 10BASE-T1L sits in the Ethernet PHY family tree, below 100BASE-T1 and 1000BASE-T1 automotive PHYs, and alongside 10BASE-T1S for shorter-reach multidrop industrial segments. Key features include compliance to IEEE 802.3cg 10BASE-T1L, IEC 61000-4-4 EFT ±4 kV at 5 kHz and 100 kHz, integrated voltage-mode line driver with external MDI termination to support intrinsic safety (IS) barriers, and an MDIO/SPI management interface. The very-low-noise coupled receiver architecture supports PoDL (Power over Data Line) signature detection and operates across industrial -40C to +105C temperature ranges. Architecturally, the DP83TD510E combines a DSP-based adaptive equalizer with a low-jitter PLL clock recovery loop, allowing the receiver to recover 10 Mbps NRZ data on cables exceeding 1.5 km with 18 AWG wiring. External MDI terminations allow designers to insert IS barriers between the PHY and the cable, a critical requirement in hazardous-area field installations. Typical applications include process field transmitters, building automation controllers, remote sensor backhaul over existing 2-wire fieldbus cabling, solar inverter monitoring, and long-reach industrial IoT nodes. The intrinsic-safe support also makes it a fit for Class I Div 2 hazardous locations in oil & gas. When designing with the DP83TD510ERHBR, prioritize a solid 4-layer PCB stack-up with a continuous ground plane beneath the PHY to meet the IEC 61000-4-4 EFT target. Place the external MDI termination network as close as possible to the MDI pins to minimize common-mode loop area and preserve IEEE 802.3cg return-loss margins.

DP83TD510ERHBT - IEEE 802.3cg 10Base-T1L Ethernet PHY | TI
The Texas Instruments DP83TD510ERHBT is an ultra-low-power Ethernet physical layer (PHY) transceiver compliant with the IEEE 802.3cg 10Base-T1L specification, housed in a 32-pin VQFN (5x5 mm) package. It supports 10 Mbps full-duplex transmission over a single twisted-pair cable with reach up to 1 km, making it ideal for long-distance industrial Ethernet. The device operates from a single 3.3V supply and includes an integrated 25 MHz reference clock output to clock companion MCUs. A 10Base-T1L PHY is a physical-layer transceiver defined by the IEEE 802.3cg standard for single-pair Ethernet (SPE). It enables 10 Mbps full-duplex data on a single balanced twisted pair, dramatically reducing cabling cost and weight compared to traditional 100BASE-TX which requires two pairs. The DP83TD510E sits at the bottom of the OSI physical layer, translating MII/RGMII digital data from a host MAC into analog signaling on the single-pair cable, and supports cable reaches up to 1 km at 1.0 Vpp or 200 m+ at 2.4 Vpp, enabling Ethernet deployment in industrial process automation, building automation, and field-sensor networks where 100BASE-TX distances and four-wire harnesses are impractical. Key features include ultra-low power consumption (approximately 130 mW active per the product page), integrated cable diagnostics with built-in self-test and loopback modes, and MII/RGMII MAC interface compatibility. The device operates over the industrial temperature range of -40C to +125C and supports 1.0 Vpp or 2.4 Vpp transmit amplitude for compliance with both 10Base-T1L and longer-reach point-to-point links. The exposed thermal pad on the VQFN-32 package simplifies PCB thermal management in sealed industrial enclosures. Architecturally, the DP83TD510E integrates the analog front-end, PHY DSP, MAC interface logic, and clock generation into a single CMOS die, eliminating external magnetics in many configurations and reducing BOM cost. The device supports both 1.0 Vpp (10Base-T1L standard) and 2.4 Vpp (extended-reach) signaling modes selectable via strap or register configuration. Wake-on-LAN and cable-fault detection further enhance its suitability for always-on industrial field nodes. Typical applications include industrial process sensors, building automation controllers, remote I/O modules, and field instruments requiring Ethernet connectivity. The 1 km reach removes the need for repeaters in many factory-floor and process-plant topologies. Compared to RS-485, 10Base-T1L provides full-duplex operation, deterministic latency, and standardized Ethernet protocol stack interoperability. When designing with the DP83TD510ERHBT, route the single-pair differential traces as a 100-ohm differential transmission line with ground reference, place the decoupling capacitors within 2 mm of the supply pins, and follow the manufacturer reference layout for the MDI interface. The integrated 25 MHz reference clock output eliminates the need for an external crystal in many MCU designs, but a high-quality crystal or oscillator should still be used when low PPM accuracy is required for timing-sensitive applications.

DW1000-I-TR13 - IEEE 802.15.4 UWB Transceiver IC | Qorvo
The Qorvo DW1000-I-TR13 is a fully integrated IEEE 802.15.4-2011 IR-UWB (Impulse Radio Ultra-Wideband) low-power transceiver IC covering 3.5 GHz to 6.5 GHz, supporting data rates up to 6.8 Mbps with a receive sensitivity of -107 dBm, housed in a 48-pin VFQFN package with exposed pad. A UWB transceiver is a radio IC that communicates using extremely short nanosecond-scale pulses spread over very wide bandwidth (typically 500 MHz or more per channel), rather than a narrowband modulated carrier. In the power-management and connectivity hierarchy of an embedded system, the DW1000 sits in the RF & Wireless > RF Transceivers layer, feeding ranging and data results to a host MCU over SPI. Because UWB pulses have sharp time-domain edges, time-of-flight between two radios can be measured with sub-nanosecond resolution, which is what enables centimeter-level positioning that Bluetooth and Wi-Fi cannot achieve. Key features of the DW1000 include two-way ranging (TWR) and TDoA location capability with 10 cm position accuracy, six programmable channels across the 3.5-6.5 GHz UWB spectrum, four programmable preamble lengths and data rates up to 6.8 Mbps, and operation compliant with IEEE 802.15.4-2011 (originally 802.15.4a). The device integrates the analog front end, receiver and transmitter, needing only an external 38.4 MHz crystal and a few passive components to form a complete UWB radio. On the receive side the DW1000 uses a direct-conversion analog receiver with programmable gain control, while the transmit side is a digitally generated pulse-based transmitter; both are synchronized to the 38.4 MHz crystal reference. The IC is controlled through an SPI slave interface, and the Decawave (now Qorvo) driver stack supports TDoA tag/anchor frameworks, SS-TWR and DS-TWR ranging modes. Its low-power architecture supports tag duty-cycling for battery-powered asset tags. Typical applications include indoor real-time location systems (RTLS) with 10 cm accuracy, warehouse and factory asset tracking, robotics navigation and drone swarm relative positioning, and secure keyless entry. Design consideration: UWB antenna placement and crystal tolerance directly affect ranging bias; follow the Qorvo reference design (DWM1000 module and related EVB1000 board) layouts and calibration guidance to meet the 10 cm accuracy figure.

DW1000SB - IEEE 802.15.4 UWB Transceiver IC 10cm | Qorvo
The Qorvo DW1000SB is a fully integrated single-chip Ultra Wideband (UWB) low-power low-cost transceiver IC compliant to IEEE 802.15.4-2011, capable of two-way ranging or TDoA location with a precision of 10 cm, housed in a 48-pin QFN package. An Ultra Wideband transceiver is a short-range, high-bandwidth radio device that transmits data using very short nanosecond-duration pulses spread across a wide spectrum (several GHz). Within the wireless communication hierarchy, UWB sits alongside narrowband technologies such as Bluetooth Low Energy, Zigbee, and Wi-Fi, but occupies its own niche: impulse-radio UWB enables centimeter-level time-of-flight measurement that narrowband radios cannot achieve, making it the physical layer of choice for indoor positioning, asset tracking, and secure ranging systems. Key features of the DW1000SB include full compliance with the IEEE 802.15.4-2011 UWB physical layer standard, two-way ranging (TWR) and time-difference-of-arrival (TDoA) location support to 10 cm accuracy, and high-rate data transfer for concurrent communication and ranging. The single-chip integration minimizes the external bill of materials, requiring only a few passives plus an antenna to form a complete UWB node. Architecturally, the DW1000 integrates the analog RF front end, pulse generator, digital baseband, and MAC-level hardware in one die. Its receiver captures extremely narrow pulses with high time-resolution, which is what underpins the precise timestamping that yields centimeter-accurate distance calculations. The IC communicates with a host microcontroller over a standard SPI interface. Typical applications include real-time location systems (RTLS) for warehouses and factories, asset tracking tags and anchors, autonomous robot and drone navigation in GPS-denied indoor environments, and secure keyless entry systems where distance bounding prevents relay attacks. Design consideration: accurate timestamping performance depends heavily on crystal oscillator quality and antenna delay calibration; budget for per-unit antenna delay calibration in production to preserve the 10 cm ranging precision. This page synthesizes distributor sourcing data, drop-in alternatives, and practical design notes not found in the manufacturer datasheet, giving engineers a complete selection view in one place.
DWM1001C - UWB Transceiver Module with nRF52832 | Qorvo
The Qorvo DWM1001C is a 6.5 GHz ultra-wideband (UWB) transceiver module with integrated BLE 4.0 (2.4 GHz), an ARM Cortex-M4 MCU and a motion sensor, in a surface-mount castellated module package. An ultra-wideband transceiver module is a complete wireless subsystem that integrates an RF transceiver IC, antenna, timing references and often a host microcontroller into a single certified package. Within the wireless hierarchy, it sits above bare transceiver ICs (such as the DW1000) and below finished IoT devices, providing IEEE 802.15.4a UWB communication with centimeter-class ranging for real-time location systems (RTLS). Key features include the DW1000 UWB transceiver IC implementing IEEE 802.15.4a on UWB Channel 5 (centered at 6.5 GHz), an integrated UWB antenna plus a Bluetooth antenna with all RF circuitry on-board, the Nordic Semiconductor nRF52832 SoC combining an ARM Cortex-M4 CPU with 512 kB flash and 64 kB RAM, and an integrated motion sensor. Production calibration is stored permanently in the DW1000 OTP memory, with the module calibrated to meet the regulatory power spectral density limit of -41.3 dBm/MHz. The architecture pairs the DW1000 UWB PHY with the nRF52832 2.4 GHz wireless SoC over an internal interface, so a single module handles both precise two-way-ranging UWB positioning and low-power BLE connectivity. The supplied PANS firmware stack provides a two-way-ranging RTLS implementation supporting anchor, tag and gateway roles out of the box, significantly shortening time to market. Typical applications include indoor asset tracking, RTLS anchors and tags, warehouse and logistics localization, and IoT sensor nodes that need both precise location and BLE backhaul. The certified module form factor (FCC compliant variant) removes the RF design and regulatory burden from the host PCB. Design consideration: because the module is factory calibrated in production, avoid reworking or reflowing the module more times than the datasheet profile allows, and route no high-speed signals directly beneath the integrated UWB antenna keep-out area. This page synthesizes distributor pricing, verified Qorvo module family comparisons and practical RTLS design guidance not found in a single manufacturer datasheet.
DWM3000TR13 - UWB Transceiver Module 6.8Mbps | Qorvo
The Qorvo DWM3000TR13 is a fully integrated Ultra-Wideband (UWB) transceiver module based on the Qorvo DW3110 IC, supporting 6.25 GHz to 8.25 GHz operation, data rates up to 6.8 Mbps, and 10 cm precise asset location accuracy, in a compact surface-mount module with an integrated ceramic patch antenna. An Ultra-Wideband transceiver module is a complete radio subsystem that integrates the antenna, all RF circuitry, power management, and clock circuitry in a single shielded package. Within the wireless positioning hierarchy, UWB modules sit alongside 802.15.4/Zigbee and Bluetooth radios but deliver centimeter-level time-of-flight ranging that narrowband technologies cannot match, making them a cornerstone technology for indoor asset tracking and secure keyless entry. Key features of the DWM3000TR13 include support for two-way ranging (TWR) and TDoA (Time Difference of Arrival) location systems, IEEE 802.15.4z compliance, and interoperability with the Apple U1 and U2 chips. The module is designed to be compliant with the FiRa PHY and MAC specifications, enabling interoperability with other FiRa-compliant devices across ecosystems. The DW3110 baseband and RF architecture integrates the complete UWB signal chain, simplifying host integration to a simple SPI interface and power connections. Because all RF matching, crystal, and antenna tuning are completed inside the module, designers avoid the most difficult aspects of UWB RF design, and 6.25 GHz to 8.25 GHz coverage supports UWB channels in the 6.5 GHz and 8 GHz bands including channel 5 compatibility with the earlier DWM1000. Typical applications include indoor asset tracking, smart-door keyless entry systems, RTLS (real-time location systems) in factories and warehouses, and secure automotive hands-free access where 10 cm positioning precision enables true user-intent detection. Design consideration: the module is pin and size compatible with the Qorvo DWM1000, which eases migration, but designers should verify antenna keep-out areas and host supply sequencing per the manufacturer datasheet. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet.
EC21AFA-512-STD - LTE Cat 1 M2M Module | Quectel
The Quectel EC21AFA-512-STD is an LTE Cat 1 cellular module for M2M and IoT applications, delivering maximum downlink data rates up to 10 Mbps with LTE and WCDMA (3G) fallback support, in a surface-mount card-edge (LCC) package without an integrated antenna. The AFA suffix designates the North America variant, targeting carriers across the US and Canada. An LTE Cat 1 module is a category of LTE UE device class defined for low-cost, low-power machine-type communication. Within the wireless connectivity hierarchy (cellular module -> RF transceiver module -> wireless communication device), Cat 1 sits above Cat M1/NB-IoT in throughput but below Cat 4 and higher, making it the traditional choice for 2G/3G sunset migrations where a full-speed LTE fallback to WCDMA is required without the cost of higher LTE categories. Key features include cost-effective LTE Cat 1 connectivity with downlink speeds up to 10 Mbps, integrated WCDMA fallback for coverage resilience, and on-module memory comprising 4 Gbit ROM and 2 Gbit RAM, which supports embedded applications and firmware headroom. Because the antenna is external, designers retain full flexibility in antenna selection and placement for optimal RF performance in enclosures. The EC21 series architecture integrates the cellular modem, baseband, RF transceiver, and memory into a single LCC-style castellated package designed for reflow soldering onto the host PCB, a pattern common across Quectel's EC2x family, which simplifies layout reuse across family members. Typical applications include telematics and fleet tracking units, smart metering and utility gateways, industrial routers and DTUs, security and alarm panels, and POS terminals - all scenarios where reliable mid-rate cellular data and long product lifecycles matter more than peak throughput. A key design consideration is thermal and RF layout: the module must be placed with adequate ground plane and the external antenna matched per the carrier band plan for the North America variant; power supply sequencing and a stable 3.3-4.2 V rail with sufficient burst current are critical for LTE transmit bursts.

EM4200 - 128-bit 125kHz Read-Only RFID IC | EM Microelectronic
The EM Microelectronic EM4200 is a 128-bit read-only CMOS low-frequency contactless identification IC designed to operate at 125 kHz carrier frequency for electronic Read Only RF transponders. Per the EM Microelectronic datasheet, the part integrates a 128-bit laser-programmed ROM memory, an on-chip resonance capacitor, and supports ISO 11785-compliant modulation with Manchester encoding. The die is supplied as a bare chip for inlay/coin/card embedding or in the EM4200A6DF2C-001+ 2-VDFN package variant. An RFID (Radio Frequency Identification) transponder IC is a passive silicon device that harvests energy from an incident electromagnetic field, stores a unique identification code in non-volatile memory, and transmits that code back to an interrogator via load modulation. Within the RFID taxonomy, the EM4200 is a low-frequency (LF, 30-300 kHz) passive read-only tag IC; within the LF tier it belongs to the 125 kHz proximity-ID family used for contactless cards, animal tagging, and access control. LF read-only tags sit below HF (13.56 MHz) and UHF (860-960 MHz) passive ICs in the RFID hierarchy, but offer superior performance near metal and water. Key features include: 128 bits of factory-locked memory (vs. 64 bits in EM4100/4102), supporting up to 100 billion unique identification codes; direct drop-in compatibility with EM4100/4102 and EM4005/4105 readers because the RF protocol, modulation, and 32-bit unique-ID framing are preserved; ISO 11785 animal-ID compliance; an operating frequency range of 100 kHz to 150 kHz; and typical read ranges of a few centimeters at 5 V antenna drive. The on-chip resonance capacitor eliminates the need for an external tuning capacitor in standard transponder layouts. Architecturally, the EM4200 uses a CMOS rectifier front-end, a bandgap-derived voltage reference, and a clock-recovery block synchronized to the 125 kHz carrier. The data path is hard-wired to the laser-programmed ROM array; there is no EEPROM, no write channel, and no anti-collision logic. This single-purpose silicon floor plan gives the EM4200 a cost advantage over the rewritable T5577/EM4305 family but limits it to read-only applications. Typical applications include 125 kHz proximity access cards, animal identification ear tags, industrial key fobs, parking transponders, and time-attendance badges. The EM4200 is the modern replacement for the discontinued EM4100/EM4102; an existing EM4100 reader decodes an EM4200-programmed credential identically. Designers should confirm antenna inductance (typically 1.0-7.5 mH) matches the on-chip resonance capacitor for the target reader field strength. When selecting an RFID transponder IC, decide whether read-only is sufficient - if credential reprogramming is needed, choose a writable chip such as T5577 or EM4305 instead. For pure read-only credentials where EM4100 protocol compliance is required, the EM4200 (original EM Microelectronic die) and TK4100 (Chinese second-source) are the dominant choices. This page synthesizes the EM Microelectronic datasheet, distributor stock data, protocol-level cross-reference information, and direct drop-in alternatives (TK4100, EM4100, EM4102) into a single engineering reference not available from any single distributor page.
