STM8S207R6T6

STM8S207R6T6 - 24MHz 8-Bit MCU 32KB Flash LQFP-64 | STMicroelectronics

The STMicroelectronics STM8S207R6T6 is a performance-line 8-bit STM8S microcontroller built around a CISC Harvard architecture core running at 24 MHz (20 MIPS) with 32 KB of on-chip Flash program memory and up to 2 KB of SRAM plus an integrated EEPROM data area. It integrates a 10-bit ADC, two 16-bit timers plus one 8-bit timer, two UARTs, SPI, I2C, and CAN, all in a 64-pin LQFP (T6 suffix) package operating from 2.95 V to 5.5 V. The device is positioned in the STM8S20xxx family which scales from 32 KB to 128 KB Flash and is intended for cost-sensitive motor-control, appliance, and industrial-control applications. An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, non-volatile program memory, working RAM, and peripherals onto one silicon die. The STM8 family uses a CISC 8-bit core with a 16-bit instruction word, giving higher code density than legacy 8051 cores while retaining the predictable interrupt latency and deterministic timing that embedded control designers prefer. The STM8S207 series specifically belongs to the STM8S "performance line," sitting above the access-line STM8S103 and below the value-line STM8S105, and is paired with ST's Cosmic, IAR, and Raisonance toolchains plus the free STVD development environment. Key features of the STM8S207R6T6 include a 20 MIPS peak instruction throughput at 24 MHz, integrated CAN 2.0B interface, a 1 Mbyte linear address space, a single-wire SWIM debug interface, and an embedded bootloader stored in ROM for in-application Flash programming. The device offers 38 GPIOs with 5 V tolerance on most pins and supports up to 16 external interrupts. Watchdog, auto-wakeup, and a 4-level low-power run/wait/slow/halt scheme allow the device to drop quiescent current below 5 uA in Halt with full RAM retention. Architecturally, the STM8S core pairs a 32-bit program address bus with a 24-bit data address bus and supports up to 16 Mbytes of linear addressing for data, while code is read from a separate Flash bus. This Harvard split removes fetch-decode stalls that plague older 8-bit Von Neumann designs and is the reason the family reaches 20 MIPS at 24 MHz without wait states. A 32 KB Flash variant such as the STM8S207R6 sits at the low-memory end of the family, sharing the same peripheral set as the larger 64 KB (R8) and 128 KB (RB) siblings. Typical applications include BLDC/PMSM motor control in appliances, HVAC fan and pump control, smart metering, lighting ballast control, industrial sensor hubs, and CAN-connected remote I/O nodes. The integrated CAN controller, combined with 32 KB Flash, makes the part a good fit for distributed industrial nodes that need deterministic on-chip comms without an external transceiver MCU. When designing with the STM8S207R6T6, pay attention to the 5 V I/O tolerance (most pins are true 5 V tolerant, but a few high-current pins are FT-compat only) and to the SWIM pin shared with NRST; the debug probe needs a tri-state buffer on the SWIM line for in-circuit debugging without disabling reset. The internal 16 MHz HSI RC is accurate to about 1 percent after user trimming, but designs that need CAN bit-time accuracy must select the external HSE crystal option.

When designing with this MCU, ensure proper decoupling of the VDD and VDDA pins with 100 nF capacitors placed close to the device. The internal RC oscillator can be used for cost-sensitive designs, but for precise timing, an external crystal is recommended. The STM8S207S8T6 supports in-circuit programming and debugging via the SWIM interface, which requires a single-wire connection and simplifies firmware updates.

STPA001

STPA001 - 4 x 50W Class AB Audio Amplifier | STMicroelectronics

The STMicroelectronics STPA001 is a 4-channel Class AB audio power amplifier built with Multipower BCD technology and MOSFET output stages for high-power car-radio systems. It supports operation down to 6 V, includes a fully complementary P-channel/N-channel output structure for rail-to-rail output swing, and is identified as a quad bridge power amplifier rated up to 50 W per channel under the manufacturer’s stated test conditions. The device is supplied in a 25-Flexiwatt vertical package. A Class AB audio amplifier is a linear power-amplifier category that uses conduction overlap between push-pull output devices to reduce crossover distortion compared with Class B designs. An audio power amplifier converts a low-level audio signal into a current- and voltage-capable drive signal for loudspeakers. STPA001 occupies the power-amplifier IC, audio amplifier, and automotive infotainment electronics hierarchy rather than a small-signal or signal-conditioning amplifier role. Key features include MOSFET output power stages, high output-current capability, low Hi-Fi-class distortion, low output noise, excellent 2 Ω driving capability, standby support, and disturbance immunity. The manufacturer describes operation down to 6 V as suitable for automotive start-stop battery profiles. Its bridge configuration is intended for car-radio speaker loads, where differential speaker drive can increase usable output voltage into the load compared with a single-ended output. The P-channel/N-channel complementary output architecture is significant because it provides rail-to-rail output-voltage swing while reducing saturation losses. That behavior helps maximize the useful output signal available to the speaker and supports the amplifier’s high-power automotive use case. The IC is intended for audio systems where low distortion and controlled output noise are more important than the efficiency of a switching audio stage. Typical applications include automotive head units, car-radio power stages, four-channel speaker systems, audio sub-system amplification, and other vehicle infotainment platforms. The 6 V minimum operating capability makes it relevant to modern vehicle electrical environments, particularly where battery voltage can fall during engine stop or cranking events. The bridge outputs must be paired with the appropriate speaker wiring arrangement shown in the manufacturer’s application information. The main design consideration is power dissipation and heat spreading in the 25-Flexiwatt package. Actual thermal performance depends on supply voltage, speaker impedance, output power, channel loading, PCB copper, and ambient temperature. A replacement must match the package footprint, pinout, bridge-output topology, voltage range, channel count, and thermal conditions; simply matching nominal wattage is not sufficient for a safe drop-in substitution. This page consolidates the verified STPA001 product description, manufacturer datasheet, distributor listing information, and application guidance. It also distinguishes documented facts from parameters that were not supplied, avoiding invented ratings or unsupported replacement claims.

The standby and mute controls support system-level power management, while clip and offset detection support diagnostic or protection functions. The MOSFET output stage is designed for rail-to-rail output swing and high output current. STMicroelectronics describes the device as a class-AB audio power amplifier intended for high-power car radio applications. The datasheet also identifies its 27-Flexiwatt vertical package, which is a thermally relevant power-dissipation package and must be mounted with suitable copper and thermal design. Typical uses include automotive head-unit amplifier stages, car-radio speaker drives, four-channel cabin audio systems, and other bridge-tied audio loads where a low-voltage battery supply is available. The four-channel architecture allows independent regulation of four speaker outputs when configured with the required passive network and load arrangement. Designers should confirm the exact load impedance, supply voltage, thermal pad implementation, output-filter network, and pin-level application circuit in the STMicroelectronics datasheet before layout. Because power dissipation rises with voltage difference and output current, the PCB copper area and thermal path are critical. This page combines verified manufacturer and distributor information with engineering guidance for amplifier selection, thermal implementation, and application planning.

A Class AB audio amplifier is an audio amplifier that uses conduction overlap between its output transistors to reduce crossover distortion compared with a pure Class A amplifier. In the broader electronics hierarchy, an audio amplifier belongs to amplifier ICs, analog signal-chain ICs, and semiconductor components. The bridge-tied-load arrangement uses each output stage differentially, allowing speaker current flow in both directions without a conventional DC-blocking output capacitor. Key verified features include four output channels, Class AB operation, up to 50 W per channel as stated by distributor listings, a 27-pin horizontal Flexiwatt package, standby and mute control, clip detection, and offset detection. The standby function can place the amplifier into a low-power state, while mute supports controlled audio attenuation. Clip and offset detection give the surrounding controller useful status signals for protecting the output stage or diagnosing abnormal operation. The STPA001 family uses MOSFET technology for its audio output stage and targets automotive head units, where four speakers or multiple powered speaker channels are common. Compared with an external discrete amplifier made from many transistors and resistors, the integrated quad amplifier reduces board area and assembly effort. Its principal engineering trade-off is substantial heat: actual channel power depends on supply voltage, speaker impedance, distortion limit, thermal conditions, and PCB copper, none of which is fully specified in the supplied data. Typical applications include car-radio head units, automotive infotainment systems, four-speaker cabin audio, powered multimedia enclosures, and low-voltage high-power audio racks when the thermal and supply conditions match the complete manufacturer specification. Each speaker output must connect to a bridge-tied load; grounding either speaker terminal to chassis ground is not an equivalent wiring method. Before layout, obtain the manufacturer datasheet and verify the exact pinout, supply limits, speaker impedance, output-power conditions, thermal resistance, protection limits, exposed-tab connection, and decoupling requirements. Keep the power ground and output-current paths compact, use the prescribed input and bypass capacitors, and thermally couple the horizontal Flexiwatt tab to the PCB copper according to the manufacturer layout guidance. This page consolidates verified distributor descriptions, sourcing information, application context, and design cautions. Parameters not present in the supplied sources remain explicitly marked for verification rather than being inferred from generic Flexiwatt or Class AB amplifier data.

STPA001H

STPA001H - 4 x 50W Class AB Audio Amplifier | STMicroelectronics

The STMicroelectronics STPA001H is a four-channel Class AB audio power amplifier rated at 4 x 50 W and supplied from 6 V to 18 V. It is packaged in a 25-Flexiwatt horizontal through-hole package with formed leads. The device provides standby and mute inputs, clip detection, and a diagnostics output. According to the manufacturer datasheet, STPA001H is intended for high-power car-radio and automotive audio systems. A power audio amplifier is an integrated analog device that drives loudspeakers from a lower-voltage audio input while delivering the voltage and current required by the load. The STPA001H uses four independent Class AB output channels in a bridge-tied-load arrangement. In this topology, each channel drives the two terminals of a speaker differentially, improving output capability while avoiding a direct ground connection at the load. Key verified features include four 50 W outputs at a 4 Ω load, Class AB operation, 6 V to 18 V supply operation, and 25-Flexiwatt horizontal construction. The standby and mute controls support system-level power management and signal suppression. Clip detection and the diagnostics output provide status information that can be monitored by a vehicle or audio-system controller. The manufacturer describes the STPA001 family as using MOSFET technology for high sound quality and high-power car-radio applications. The device is intended for four-channel audio architectures in which multiple loudspeaker loads must be driven from one integrated power stage. Typical uses include car-radio amplifiers, automotive sound systems, and other bridge-tied-load audio equipment. The 25-Flexiwatt package is a substantial thermal and mechanical solution compared with small surface-mount amplifier packages, making it appropriate for designs where substantial output power and heat-spreading capability are priorities. When designing around STPA001H, preserve the datasheet supply range and account for the power dissipated by the four Class AB output stages. Speaker wiring, grounding, and decoupling should be arranged to minimize hum and switching-related disturbance. The standby and mute pins should be driven according to the manufacturer’s recommended logic levels, while clip and diagnostics signals should be incorporated into system monitoring where useful. This page consolidates verified distributor and manufacturer information with application guidance, comparison fields, and design notes intended to help engineers evaluate STPA001H for high-power automotive audio designs.

STPIC6C595TTR

STPIC6C595TTR - Power Logic 8-Bit Shift Register 16-TSSOP | ST

The STMicroelectronics STPIC6C595TTR is a monolithic medium-voltage, low-current power 8-bit shift register designed for systems that drive moderate loads such as LEDs, relays, and solenoids. The device features eight 100 mA DMOS open-drain outputs with a 33 V output clamp, 4 ohm typical on-resistance, 250 mA current-limit capability per channel, and 30 mJ avalanche energy rating, all packaged in a 16-pin TSSOP with exposed pad for improved thermal dissipation. The serial-in/parallel-out shift register accepts a CMOS-compatible clock and serial data input, includes an output enable, and supports device cascading via a serial data output for multi-chip LED matrix designs. A power logic shift register is a serialized-to-parallel driver that integrates low-RDS(on) DMOS output transistors inside the same die as the shift register logic, eliminating the need for external power transistors, flyback diodes, or current-limiting resistors on every channel. Within the broader taxonomy, the STPIC6C595TTR belongs to the power logic family of integrated drivers, which sits hierarchically between general-purpose logic shift registers (74HC595) and discrete MOSFET arrays. The DMOS outputs include a built-in 33 V inductive-transient clamp, so designers can switch relay coils, solenoids, or long LED strings without adding free-wheeling diodes externally. Key differentiated specifications include 100 mA continuous output current per channel, 4 ohm typical on-resistance at logic-level gate drive, 33 V output clamp voltage for inductive switching, 250 mA current-limit capability, and serial clock rates up to 10 MHz typical. The TSSOP-16 exposed-pad package lowers thermal resistance to approximately 45 C/W on a 1 oz copper 4-layer board, enabling eight outputs to deliver full current simultaneously without a heatsink in well-designed layouts. Architecturally, the device uses a TTL-compatible serial interface and an internal low-side DMOS array. Each output is a current-limited open-drain structure that actively regulates inrush current to about 250 mA when shorted or when switching highly capacitive loads. The combination of shift register, output latch, output enable, and cascadable serial data output makes it a complete serialized power-driver stage in a single small-outline package. Typical applications include dot-matrix LED displays, 7-segment multiplexed LED panels, relay and solenoid matrices, stepper-motor unipolar winding drivers, and generic indicator or signage lighting strips. The wide output-compliance window also suits small incandescent lamps, optocoupler input arrays, and level-shifters for higher-voltage power stages. When routing the PCB, place a 0.1 microfarad decoupling capacitor directly at the VCC pin, route the exposed pad to a generous copper pour, and observe minimal-loop layout rules for the inductive ground return.

Its pulsed output provides a convenient interface for an external counter or system controller, while digital calibration supports configuration and measurement adjustment during manufacturing or system setup. The STPM13 family is described as supporting single-phase energy measurement with sensor inputs suitable for common current-sensing arrangements. The verified listing specifically names shunt, current-transformer, and Rogowski-coil sensors, as well as live and neutral monitoring for STPM13/14 variants. These features allow the device to be evaluated for different meter architectures, but the exact electrical limits, calibration procedure, register map, and timing values must be taken from the manufacturer datasheet. STPM13ATR is packaged in a 20-TSSOP surface-mount package. The package provides a compact form factor for meter electronics, and the available DigiKey result lists the part as a 20-TSSOP single-phase meter IC. Because the supplied data does not include the full electrical tables or a verified pin diagram, individual pin assignments and absolute minimum or maximum ratings are not reproduced here. The manufacturer datasheet should be consulted before PCB routing or production qualification. Typical applications include single-phase residential electricity meters, industrial energy-monitoring equipment, smart-meter power calculations, load-monitoring modules, and embedded systems that consume pulse information. The pulsed output can be connected to a counter, capture input, or energy-management controller. The choice of current sensor and the calibration strategy remain important design decisions because they influence signal conditioning, measurement accuracy, and metrology validation. For a new design, verify the exact STPM13ATR variant, supply requirements, sensor-input configuration, pulse-output behavior, and package pinout against the official STMicroelectronics datasheet.

Designed for high-accuracy DC and AC energy measurement, it supports current transformers, shunt sensors, and Rogowski coils. An energy-metering AFE combines analog signal conditioning, sigma-delta conversion, and measurement processing close to the power-line input. Within the hierarchy of analog front ends, energy-metering ICs, data converters, and power-management semiconductors, this device reduces the need for separate precision converters and preserves low-noise current measurement down to appliance standby levels. The verified device description identifies up to four independent 24-bit second-order sigma-delta ADC channels and two embedded PGLNAs. A 4 MHz oscillator provides the timing reference for the conversion system, while the high-resolution channels support accurate voltage, current, active-energy, and reactive-energy calculations. The 32-QFN package supports compact meter designs without requiring a larger through-hole footprint. The STPM3x family is specifically designed for power-line energy measurement using Rogowski-coil, current-transformer, or shunt-current sensors. By integrating measurement channels and analog gain around the sensor interface, the device helps simplify calibration and reduce sensitive high-impedance routing between external analog circuitry and a metering MCU. Typical uses include single-phase residential electricity meters, smart meters, industrial energy monitors, appliance sub-metering, power-factor monitoring, and DC energy measurement. The same AFE architecture can be used where the design must measure very low current levels, including equipment that spends substantial time in standby. PCB implementation should follow the manufacturer datasheet for QFN thermal-pad assembly, analog grounding, sensor filtering, and exposed-pad connection. Input protection and isolation are application-specific and cannot be assumed from the listed operating range. Before layout release, confirm every pin, voltage, current, accuracy, and calibration parameter against the official STMicroelectronics datasheet.

The STMicroelectronics STPM34TR is an energy-metering application-specific standard product with four independent 24-bit, second-order sigma-delta ADCs, 4 MHz oversampling and two embedded programmable-gain low-noise amplifiers, supplied in a 32-pin QFN package with exposed pad. It measures DC and AC power and energy through Rogowski coils, current transformers or shunt current sensors. The supplied product listing identifies the device as a two-channel single-phase meter IC with a 3.3 V-class supply and a 5 x 5 mm footprint. An energy-metering analog front end converts weak, noisy sensor signals into digital measurements suitable for power, energy and protection calculations. Unlike a general-purpose ADC, the STPM3x family integrates metering-specific channels, programmable gain, references and signal conditioning. It supports power-line measurement systems using Rogowski coils, current transformers or shunts, with the sensor choice determining bandwidth, isolation, accuracy and PCB complexity. The four 24-bit second-order sigma-delta channels provide high-resolution acquisition for multiple voltage and current inputs. A 4 MHz oversampling mode can improve conversion performance, while two embedded PGLNAs reduce the need for separate low-noise gain stages in suitable signal paths. Independent reference and channel shutdown controls provide a route to lower power consumption when not every measurement channel is continuously required. The operating supply is verified at 2.95 V to 3.65 V. Distributor and technical listings identify the industrial temperature range as -40°C to +105°C, and the package as a 5 x 5 mm QFN-32 with exposed thermal pad. The exposed pad must be connected to the appropriate ground plane and handled with the thermal layout requirements specified by the manufacturer datasheet. Typical applications include single-phase and three-phase energy meters, utility-grade residential metering, industrial power monitors, appliance energy measurement, solar and building-energy monitoring, and systems using Rogowski coils or isolated current transformers. The STPM34TR is particularly appropriate when the design requires multiple high-resolution measurements and dedicated metering signal conditioning rather than a general-purpose data converter. For a new design, verify sensor compatibility, channel assignment, reference configuration, gain settings, calibration method and exposed-pad thermal management against the manufacturer datasheet before layout. The cited web data does not provide a verified unit price, stock quantity, detailed pin names, RoHS declaration, REACH declaration or automotive qualification status.

STR731FV2T6 - ARM7TDMI 32-bit MCU 256KB Flash | STMicroelectronics

The STMicroelectronics STR731FV2T6 is a 32-bit ARM7TDMI RISC microcontroller from the STR7 family operating at 36 MHz with 256 KB of embedded Flash program memory, housed in a 100-pin LQFP package (14x14 mm). It integrates a rich communications peripheral set including 3 CAN 2.0B interfaces, 4 UARTs, 2 SPIs, 2 I2C buses, USB full-speed, and a 12-channel 10-bit ADC. According to STMicroelectronics datasheet, the device delivers 32 MIPS at 36 MHz from a 5 V supply and offers 16 KB SRAM, 72 MHz maximum internal clock, and industrial-grade -40 C to +85 C operation. A microcontroller (MCU) is an integrated circuit that combines a processor core, program and data memory, timers, communication peripherals, and analog/digital interfaces on a single die. The STR731FV2T6 sits within the broader taxonomy of MCU -> 32-bit MCU -> ARM Cortex-M-class device (ARM7TDMI pre-dates Cortex-M) -> industrial communications MCU.

Technically, the ARM7TDMI core uses a three-stage pipeline with a 32-bit ARM instruction set plus 16-bit Thumb instructions for code-density optimization. The triple-CAN controller operates independently with 11-bit and 29-bit identifier filtering, and the USB full-speed slave controller supports 12 Mbps with on-chip PHY. Industrial-grade EMC, ESD protection, and wide supply tolerance (4.5 V to 5.5 V) suit harsh environments requiring extended reliability. Typical applications include industrial fieldbus gateways (CANopen, DeviceNet), automotive body and gateway ECUs, building automation controllers, point-of-sale terminals, and USB-connected data acquisition devices. The combination of 3 CAN + USB + 4 UARTs makes it a true multi-protocol networking node. Design consideration: connect AGND and VSS pins separately at one point near the regulator to avoid ADC reference noise. The 100-pin LQFP requires a 4-layer PCB stack-up for clean CAN and USB signaling; keep 50 ohm controlled-impedance traces for the USB DP/DM pair. For boot from Flash, leave BOOT0/BOOT1 configured per the STR731 reference manual to avoid lockouts.

STULPI01BTBR

STULPI01BTBR - USB 2.0 ULPI OTG Transceiver, 36-TFBGA | ST

The STMicroelectronics STULPI01BTBR is a high-speed USB 2.0 physical-layer transceiver that is fully compliant with the ULPI (UTMI+ Low Pin Interface) specification and the USB On-The-Go (OTG) supplement, providing a complete PHY solution for any high-speed USB host, device, or OTG dual-role controller core operating at 480 Mbps. Housed in a compact 36-ball TFBGA (3.5 x 3.5 mm) package, the device implements the UTMI+ low-pin-count 12-pin bridge to the application ASIC, dramatically reducing the SoC I/O count required for USB connectivity compared to legacy UTMI designs that needed 30+ pins. A USB 2.0 transceiver (also called a USB PHY) is the analog front-end of a USB system, handling the high-speed differential signaling on the DP/DM lines, the low-/full-speed termination, the 1.5 kohm pull-up for device detection, the 15 kohm pull-down on the host side, the OTG session-request comparator, and the charge-pump for VBUS drive. The STULPI01B sits in the hierarchy: USB transceiver (PHY) -> USB interface IC -> interface and transceiver -> semiconductor, and is typically paired with an application processor that implements the upper protocol layers over the ULPI link. Key features include 480 Mbps High-Speed (HS), 12 Mbps Full-Speed (FS), and 1.5 Mbps Low-Speed (LS) operation; integrated 45 ohm Hi-Speed termination and switching between HS and FS/LS terminations; 8-bit SDR ULPI interface operating at 60 MHz; integrated charge pump for OTG VBUS pulsing; on-chip pull-up/pull-down resistors for DP/DM; host, device, and OTG dual-role modes selectable via the ULPI ID pin; I/O supply 1.8 V to 3.3 V; and a 3.0 V to 4.5 V analog supply rail. The chip supports suspend, resume, remote wakeup, and chirp handshake generation required for HS negotiation. Technically the PHY uses a precise 480 MHz PLL locked to the 60 MHz ULPI clock, an HS current-mode driver with controlled edge rates for USB IF compliance, a 3.3 V tolerant ULPI link, and on-die ESD protection on the DP/DM lines. By outsourcing the analog and analog-digital mixed-signal PHY to the STULPI01B, designers can implement the USB digital controller in their standard-cell ASIC or FPGA fabric without requiring an expensive analog process node, which is why this architecture is dominant in mobile, set-top, and automotive infotainment silicon. Typical applications include USB OTG dual-role ports in smartphones, tablets, and portable media players, USB device ports in printers and storage, USB host capability in set-top boxes and automotive head units, USB-to-UART bridge ASICs, and embedded computing platforms that add USB to an FPGA or microcontroller without an internal PHY. The BGA package and small footprint suit 4-layer mobile mainboards where board area is at a premium. When laying out a board using the STULPI01BTBR, place the device as close as possible to the USB connector, keep DP/DM traces matched to 90 ohm differential impedance, and provide a clean analog 3.3 V supply decoupled with a 100 nF + 4.7 uF combination within 5 mm of the VCC pin. The ULPI bus to the SoC should be length-matched and routed over a continuous reference plane to preserve 60 MHz SDR timing margin. This page synthesizes distributor pricing, drop-in same-family and cross-brand ULPI alternatives, and layout notes not collected in a single place on the manufacturer datasheet, giving hardware engineers a one-stop reference for USB OTG PHY selection.

It integrates 5 V VBUS management, attach and orientation detection, VCONN supply for electronically marked cables, and short-to-VBUS protection on the configuration channel (CC) lines for both host-side and device-side USB Type-C implementations. An interface controller IC such as the STUSB1600 sits in the USB Type-C protocol stack between the USB host/device controller (e.g., a USB-PD or USB 3.x controller) and the physical Type-C receptacle. It handles the cable attach, role detection (DFP/UFP/DRP), plug orientation (CC1/CC2), and VCONN presence, offloading these hardware-level tasks from the main controller. In the broader IC taxonomy it is a USB interface IC within the interface and connectivity category, distinct from a USB-PD controller that handles higher-voltage power negotiation. Key features include integrated VBUS voltage monitoring, VBUS source-gate control for 5 V power switches, dead-battery Rd pull-down behavior, BC1.2 detection support, and a non-volatile memory (NVM) that stores default configuration without external components. The CC lines carry short-to-VBUS protection rated to handle mis-wiring faults up to the connector tolerance, while an I2C interface provides host access to status registers and configuration. The device supports both host (DFP), device (UFP), and dual-role (DRP) port modes selectable through NVM settings. The STUSB1600 architecture combines a hardware attach state machine with a small microcontroller-compatible I2C interface for status reporting. Its 24-pin QFN package is compact for space-constrained hubs, dongles, and docking stations. Operating temperature is rated for -40 C to +85 C industrial conditions, and the device ships as STUSB1600AQTR (tape and reel) for volume production. Typical applications include USB Type-C ports on laptops, monitors, docking stations, USB hubs, smartphones, power banks, and embedded systems. Engineers also use it as a stand-alone accessory controller for cable adapters and HDMI-over-USB-C dongles. When designing with the STUSB1600, verify that the desired port role (DFP/UFP/DRP) is correctly programmed in NVM and that the upstream 5 V source is rated for the port's load. Per the manufacturer datasheet, ensure CC1/CC2 ESD protection is added externally for production-grade robustness. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet, helping engineers evaluate the STUSB1600 for new designs and existing BOM migrations.

STUSB4500LBJR

STUSB4500LBJR - USB Type-C Sink PD Controller, 25-WLCSP | ST

The STMicroelectronics STUSB4500LBJR is a standalone USB Type-C port controller for power-sinking devices, presented in a 25-ball WLCSP package (2.59 x 2.59 mm). It implements USB Power Delivery 2.0 sink negotiation up to 20 V / 5 A (100 W) over the USB Type-C connector and integrates an I2C interface for host configuration, VBUS monitoring, and OVP/OCP protection. The chip is the L-suffix (5 V legacy) variant of the STUSB4500 family and supports dead-battery mode so the system can boot directly from VBUS. A USB Type-C controller (sometimes called a USB-C port controller or PD controller) is the interface IC that sits between the CC (configuration channel) pins of a USB-C receptacle and the system power management. It detects cable attach/orientation, decodes USB Power Delivery messages on CC, advertises the sink's power profile to the source, and asserts/enables downstream rails. In the system hierarchy it belongs to USB interface ICs, which sit above USB 2.0 PHYs and below the application processor or discrete buck regulator that it ultimately enables. Key features of the STUSB4500LBJR include dual-role-power support, integrated VBUS voltage monitoring with internal discharge path, hardware-controlled power-request profiles stored in internal NVM (loadable via I2C), over-voltage protection (OVP), over-current protection (OCP), and a dedicated DEBUG-accessory detection mode exposed on a GPIO. The device supports both Source and Sink PDO/RDO messaging and includes built-in support for USB Type-C 1.3 and USB PD 2.0 revision 2.0. Operating supply range is 3.0 V to 5.5 V on VDD, with VBUS tolerated up to 22 V for transient robustness. Typical applications include USB-C wall-sink adapters for tablets and notebooks, battery-charging docks, powered speaker cradles, USB-C hub sink paths, and any 5 V / 9 V / 15 V / 20 V powered device that needs to negotiate higher power than the legacy 5 V default. Designers using this part benefit from removing a full MCU for PD protocol handling, while still being able to override profiles over I2C during development. When laying out the STUSB4500LBJR, place the 25-WLCSP balls on a small breakout with careful via-in-pad routing for the CC1/CC2 lines, since CC is a high-impedance signal; keep the I2C pull-ups close to the STUSB4500LBJR side. Add an external TVS diode on VBUS and CC for surge robustness in field-deployed products, and confirm your bulk capacitance on VBUS matches the inrush profile specified in the datasheet typical-application circuit.

STUSB4500LQTR

STUSB4500LQTR - USB Type-C Sink Controller, 5V/3A, 24-QFN | STMicroelectronics

The STMicroelectronics STUSB4500LQTR is a standalone USB Type-C cable-connect controller and Power Delivery sink controller IC that targets 5 V sink applications up to 3 A (15 W). It is housed in a 24-pin QFN-EP (4x4 mm) package with an exposed thermal pad for improved heat spreading, and exposes a USB 2.0 billboard interface via an I2C control port. What is a USB Type-C sink controller? A sink controller is the side of a USB Type-C connection that receives power from a Type-C source (such as a laptop, charger, or power bank). It negotiates the voltage and current level allowed by the attached source using the USB Power Delivery (PD) protocol, then presents that negotiated voltage on its VBUS rail. The STUSB4500L is a "standalone" controller: it requires no external MCU to negotiate a PD contract, which simplifies the BOM and firmware for power-only sink devices such as docking stations, charging cradles, and USB-powered appliances. Key features include dead-battery support (a system can draw power directly from VBUS before software initializes), 5 V legacy detection, GPIO pin for debug accessory detection, integrated VBUS discharge paths, and I2C programmable source capability (PDOs) such as 5 V @ 3 A, 9 V @ 2 A, 12 V @ 2.25 A, and higher via PD 2.0/3.0 negotiation. The 4x4 mm QFN-EP footprint occupies only ~16 mm^2 of board space, making this part attractive for compact form factors. Typical applications include USB-PD powered hard-disk enclosures, USB Type-C powered speakers, industrial controllers drawing bus power, smart-home hubs with PD input, notebook replacement chargers, and USB-PD powered LED lighting. Automotive-grade variant is separately available as STUSB4500QTR. Design consideration: when using STUSB4500LQTR, ensure the CC1/CC2 pins have the correct Rd pull-down resistors and that the VBUS sense network matches your system's sink current limit. Provide adequate copper area beneath the exposed pad for thermal relief under sustained 3 A loads.

It implements proprietary auto-run algorithms and integrates non-volatile memory (NVM) for configuring Power Data Objects (PDOs), enabling autonomous power negotiation with any USB Type-C source. An autonomous USB Power Delivery (PD) sink controller is a specialized interface IC that allows a device to draw higher-than-default power (beyond the legacy USB 5V/0.9A baseline) through a USB Type-C connector. The STUSB4500QTR occupies the position of sink-side protocol layer within the USB-C ecosystem, sitting between the CC logic of the Type-C receptacle and the downstream DC-DC converter or load switch. It belongs to the broader USB interface IC category, a subset of wired connectivity controllers. Key features include support for 5V, 9V, 12V, 15V, and 20V PDOs at 5A maximum, integrated short-to-VBUS protection on CC pins (VCONN- and CC1/CC2 tolerant up to 22V), dead-battery signaling for unpowered sinks, and an I2C interface for host configuration and telemetry access. The device is USB-IF certified (TID 1074413) for USB Type-C R2.1 and USB Power Delivery R3.0 compliance, simplifying certification of the end product. Technically, the STUSB4500QTR combines a USB PD R3.0 physical layer (BMC-encoded on CC), a protocol layer state machine, an embedded 5V LDO for internal supply, and 32-byte user-configurable NVM. It offers dual-mode USB power delivery alongside legacy USB 5V fallback and supports both standard Power Delivery and the proprietary PPS (Programmable Power Supply) source negotiation through the high-resolution request message. Typical applications include USB-C powered monitors and docking stations, fast-charging smartphones and tablets, IoT gateways, industrial single-board computers, and any product migrating from legacy DC barrel jacks to USB-C. The wide-input tolerance makes it equally suited to 5V-only low-power devices and 20V/5A 100W laptops. When designing with the STUSB4500QTR, ensure the downstream sink path can handle the negotiated current up to 5A on VBUS. Use 4-wire VBUS routing on the PCB, and decouple the VCC pin with at least 1uF X7R ceramic capacitance close to the exposed thermal pad, which must be soldered to a continuous ground plane for thermal dissipation and short-to-VBUS protection immunity.
