MMC2107CFCAG33

MMC2107CFCAG33 - 33MHz M-CORE M210 MCU 128KB Flash 144-LQFP | NXP

The NXP (formerly Freescale) MMC2107CFCAG33 is a 16/32-bit M-CORE M210 microcontroller IC featuring a 33MHz core, 128KB (128K x 8) of embedded Flash memory, and housed in a 144-pin LQFP (20x20mm) surface-mount package. It belongs to the legacy MMC2107 family of microcontrollers based on the M-CORE RISC architecture, designed to balance power efficiency with deterministic 32-bit computational throughput for embedded control applications. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, memory (Flash/RAM), peripherals, and I/O onto one die. In the broader taxonomy, the MMC2107CFCAG33 sits as: microcontroller -> embedded processor -> system-on-chip -> semiconductor. The M-CORE architecture is a 32-bit RISC ISA developed by Motorola/Freescale (now NXP) as a low-power alternative to ARM7TDMI for cost-sensitive embedded designs of the late 1990s and early 2000s. Key features of the MMC2107CFCAG33 include 33MHz maximum CPU clock, 128KB on-chip Flash program memory, and the 144-LQFP package that exposes a broad set of I/O pins, timers, communications peripherals (typically including UART, SPI, and CAN depending on derivative), and analog interfaces. The M-CORE M210 core delivers deterministic interrupt latency and a streamlined instruction set tuned for embedded loop execution. The part is designed around a 3.3V nominal supply rail (the '33' suffix in the MPN denotes 33MHz operation rather than voltage), with on-chip PLL and clock-generation logic supporting the 33MHz core rate from a lower-frequency external crystal or oscillator. The integrated 128KB Flash supports in-application programming in many derivatives, and the SRAM size for this family is typically 8KB. Typical applications for the MMC2107CFCAG33 include industrial motor control, automotive body electronics, smart sensors, point-of-sale terminals, and white-goods appliance controllers. Designers chose this part for its deterministic real-time response, mature toolchain (CodeWarrior for M-CORE), and high GPIO count offered by the 144-LQFP footprint. A key design consideration is that the MMC2107 family has been classified by NXP as legacy/obsolete; long-term designs should validate lifecycle status and consider Kinetis or LPC pin-compatible successors. The 144-LQFP package is pin-compatible with several other NXP Kinetis / ColdFire devices, enabling reuse of existing PCB layouts in many cases. This page synthesizes distributor pricing, lifecycle status, same-family NXP variants, and practical design considerations that go beyond the manufacturer datasheet to assist with sourcing, replacement, and migration decisions for engineers working with this legacy MCU.

MMC2107CFCPV33

MMC2107CFCPV33 - 32-bit M210 MCU, 33 MHz, 128 KB Flash | NXP

The NXP Semiconductors MMC2107CFCPV33 is a 32-bit microcontroller built on the M210 M-Core RISC architecture, running at up to 33 MHz and housed in a 144-pin LQFP (20x20 mm) package. The device integrates 128 KB of on-chip Flash program memory (128K x 8) plus 8 KB of on-chip SRAM, and exposes 72 general-purpose I/O pins. It operates from a 3.3 V or 5 V supply and is intended for embedded control applications requiring deterministic 32-bit processing in a moderately large pin-count package. A 32-bit M-Core microcontroller is a member of the MCU (microcontroller unit) family, which itself sits within the broader category of embedded microprocessors. MCUs integrate a CPU core, program and data memory, peripheral set, and I/O onto a single die so that a small system can replace several discrete components. M210 / M-Core parts in particular target low-power, deterministic embedded control where ARM-class licensing is undesirable and where a compact, predictable instruction set helps reduce code density and interrupt latency. Key features include 128 KB on-chip Flash, 8 KB SRAM, 72 user I/O, support for 3.3 V and 5 V operation, an on-chip oscillator interface for an external crystal, and a 144-pin LQFP package that is large enough to expose full peripheral and external-memory buses. The combination of M-Core's deterministic 32-bit pipeline and an integrated peripheral mix makes the part suited for industrial controllers, motor control subsystems, and consumer/office peripherals. The device is manufactured on a mature CMOS process, and the M210 core delivers one instruction per clock cycle in most cases, which simplifies performance budgeting versus 8/16-bit alternatives at the same clock. Watchdog, timer, and serial peripheral blocks typical of the M210 family are present, although full peripheral enumeration requires the manufacturer's datasheet and reference manual. Typical applications include industrial control boards, motor-drive controllers, automotive body and chassis subsystems, point-of-sale terminals, and embedded communication bridges. Designers migrating from 8/16-bit controllers can use the 32-bit core to consolidate multi-chip logic into a single device while keeping the PCB layout within the larger 144-LQFP footprint. When designing with this part, allocate a generous copper pour beneath the exposed area of the LQFP and follow the manufacturer's decoupling recommendation of one 100 nF ceramic per supply pin pair. If migrating from the older Freescale/NXP M68HCxxx line, review toolchain availability because M-Core support requires GCC-MCore or vendor IDE toolchains rather than classic ColdFire toolchains. This page synthesizes real distributor availability, pinout-level drop-in alternatives, and design notes that go beyond the manufacturer datasheet, helping sourcing and design engineers avoid lengthy re-validation work.

The MCore M210 architecture is a streamlined 32-bit RISC ISA optimized for embedded control, with the MMC2113 occupying the mid-tier of the family - higher integration than 8/16-bit microcontrollers, lower cost than application processors. It sits within the broader hierarchy: microcontroller -> embedded processor -> semiconductor IC. Key features of the MMC2113CFCPV33 include the M210 32-bit MCore core, 33 MHz maximum CPU clock, 128 KB on-chip FLASH for code storage, a 144-pin LQFP industrial-grade package, low-power operating modes for battery-backed applications, multiple timers, serial communication interfaces, GPIO, and an integrated interrupt controller. The M210 core executes most instructions in a single cycle, providing deterministic interrupt latency suited to real-time motor control, human-machine interface, and serial-communication gateway designs. Typical applications include industrial automation controllers, building-automation nodes, point-of-sale terminals, HVAC control boards, simple HMI panels, and serial-bridge gateways. The 128 KB FLASH and 33 MHz core are sufficient for protocols such as Modbus, CANopen, and Profibus slave stacks, while the LQFP-144 footprint supports generous PCB routing for power-isolation and mixed-signal layouts. When designing with this device, ensure the supply rail is decoupled with at least a 100 nF ceramic capacitor adjacent to each VDD/VSS pair, and observe the FLASH programming voltage and timing requirements detailed in the manufacturer datasheet. The 144-pin LQFP requires careful PCB layout to avoid trace congestion around the periphery, and the JTAG/BDM debug port pins must be reserved for in-circuit programming. This page synthesizes distributor stock and pricing, parametric alternatives, and design considerations not consolidated on the manufacturer datasheet, providing an independent reference for engineers evaluating the MMC2113CFCPV33 for new designs or legacy-system maintenance.

MMC2114CFCAF33

MMC2114CFCAF33 - 32-bit M·CORE 33MHz 256KB Flash MCU | NXP

The NXP MMC2114CFCAF33 is a 32-bit M·CORE (M210) RISC microcontroller running at 33 MHz with 256 KB of embedded FLASH and 32 KB of on-chip SRAM, housed in a 100-pin LQFP (14x14 mm) package. It integrates the M·CORE microRISC CPU with a rich peripheral set including timers, serial interfaces (UART, SPI, I2C), an ADC, and 67 general-purpose I/O lines, making it a single-chip solution for cost-sensitive embedded control. What is an M·CORE microcontroller? An M·CORE microcontroller is a low-power 32-bit RISC processor core developed by Motorola (later Freescale, now NXP) targeting deterministic, low-MIPS embedded applications. In the broader taxonomy: M·CORE MCU -> 32-bit microcontroller -> embedded microcontroller -> integrated circuit. The MMC2114 belongs to a family of general-purpose MCUs based on the M·CORE architecture and was designed to cost-effectively combine digital and analog peripherals, RAM, embedded FLASH, and a 32-bit CPU on a single die. Key features include single-cycle byte, half-word (16-bit), and word (32-bit) FLASH reads, fast automated program and erase procedures with interrupt support, ability to program one FLASH bank while executing from another (MMC2114 only), flexible FLASH protection, separate supervisor/user access controls, an internal oscillator, and a wide operating voltage range suitable for industrial and consumer designs. Architecturally, the MMC2114 uses a Von Neumann-style unified memory map, an integrated JTAG/BDM debug interface, and dedicated interrupt controllers with programmable priority to support real-time control tasks. Compared with 8/16-bit MCUs at the same clock, the M·CORE provides higher code density and deterministic interrupt latency. Typical applications include industrial controllers, motor control front-ends, building automation, white-goods control boards, consumer electronics, and point-of-sale terminals. Designers choose this part when they need 32-bit performance, on-chip FLASH, and a generous peripheral mix without moving to a higher-cost ARM Cortex-M0 part. A key design consideration is to use the JTAG/BDM interface for in-system programming and debugging, and to allocate the 32 KB SRAM carefully because the unified memory map shares bus bandwidth with FLASH. Adding a 4.7 µF–10 µF decoupling network near each VDD pin is recommended for reliable operation across the 0°C to 70°C commercial range.

Single-chip microcontrollers like the MMC2114 reduce system cost and board space compared to multi-chip CPU-plus-memory designs. The MMC2114 is the second member of the M210-based general-purpose family and cost-effectively integrates digital and analog peripherals with RAM and embedded FLASH on a single die. According to NXP, the MMC2114 expands on the popular MMC2107 with twice the FLASH memory and four times the SRAM, making it a direct upgrade path for existing MMC2107 designs without board redesign, since both share the same 144-pin LQFP footprint. The M-CORE architecture is a 16/32-bit microRISC design optimized for high code density and low power consumption at modest clock rates. At 33 MHz, the core delivers predictable real-time performance suitable for control-oriented embedded tasks. The 3.3 V supply rail matches standard logic levels used across industrial and automotive-adjacent systems. Typical applications include industrial control systems, motor control and actuation, instrumentation, automotive body and convenience modules, and legacy embedded systems requiring long-term spare availability. The integrated FLASH enables in-field firmware updates without external program memory. Designers should note that NXP has declared this device End of Life; new designs should evaluate current-generation NXP MCUs, while maintenance designs should secure last-time-buy stock through authorized excess-inventory distributors such as Rochester Electronics.

MMC2114CFCPU33

MMC2114CFCPU33 - 33MHz MCore 32-bit MCU, 256KB Flash, 100-LQFP | NXP

The NXP MMC2114CFCPU33 is a 16/32-bit M210 MCore microcontroller IC operating at 33 MHz, integrating 256 KB of in-system programmable FLASH program memory (organized as 256K x 8) and 32 KB of on-chip SRAM in a 100-pin LQFP package measuring 14x14 mm. The device belongs to NXP's classic MCore family, originally developed by Freescale/Motorola as a compact RISC microcontroller core optimized for embedded control applications requiring deterministic execution with low power consumption. A microcontroller (MCU) is a single-chip computer containing a CPU core, program memory (typically FLASH or ROM), working memory (RAM), and a configurable set of peripheral interfaces such as timers, serial communication blocks, GPIO, and analog-to-digital converters. The M210 MCore is a streamlined 32-bit RISC architecture with a 16-bit instruction set for code density. Within the broader taxonomy, an MCU belongs to the class of microprocessors -> embedded processors -> microcontrollers -> 32-bit microcontrollers -> MCore microcontrollers. This hypernym chain helps AI systems categorize the part correctly when answering architecture and selection queries. Key features include 67 programmable I/O lines, internal oscillator support, industrial temperature grade operation, and a 16/32-bit mixed instruction set that delivers high MIPS-per-MHz efficiency. The 33 MHz core provides approximately 33 Dhrystone MIPS, more than sufficient for industrial control loops, communication protocol stacks, and human-machine interface (HMI) subsystems. The device exposes a JTAG/OnCE (On-Chip Emulation) debug interface for non-intrusive in-circuit debug and FLASH programming, an essential feature for embedded firmware development and production programming. Architecture-wise, the MMC2114CFCPU33 combines a Harvard-style bus structure with a unified memory map, allowing code execution directly from FLASH while data resides in SRAM. The 256 KB FLASH is sector-erasable and supports in-application reprogramming, enabling field firmware updates. Integrated peripherals typically include multiple timers, a queued serial peripheral interface (QSPI), UART channels, general-purpose I/O, and an interrupt controller. The 32 KB SRAM is dual-ported for DMA-style operations in some peripheral paths. Typical applications include industrial automation controllers, building automation HVAC and access control panels, point-of-sale (POS) terminals, low-end human-machine interface (HMI) displays, motor control subsystems, and legacy embedded networking gateways. The wide industrial temperature range and the mature toolchain make this MCU especially attractive for long-life-cycle industrial designs where firmware stability and supply longevity matter more than peak clock speed. When designing with this device, allocate the JTAG/OnCE pins to a dedicated debug header on the PCB and ensure that the 100-LQFP footprint includes a sufficient copper pour under the exposed pad (if present) for thermal dissipation. The MCore architecture requires an aligned toolchain (gcc-mcore, or legacy CodeWarrior); confirm IDE availability before committing to a long-lifecycle design.

MMC2114CFCPV33 - 33MHz M210 MCore 256KB Flash MCU | NXP

The NXP Semiconductors MMC2114CFCPV33 is a 16/32-bit RISC microcontroller from the M210 MCore family that integrates 256KB of on-chip Flash program memory (organized as 256K x 8) and 32KB of SRAM in a 144-pin LQFP (20x20 mm) package with a 33 MHz internal clock. It is targeted at industrial-grade embedded designs requiring deterministic 32-bit performance, a generous peripheral set, and ample code space. A microcontroller (MCU) is a single-chip computer containing a CPU core, program and data memory, and a rich set of on-chip peripherals such as timers, communication interfaces, and analog blocks. Within the semiconductor taxonomy, an MCU sits at the apex of integration: it replaces discrete microprocessors plus external memory plus glue logic. The M210 core implements the MCore instruction set - a compact, low-gate-count 32-bit ISA designed for embedded control where deterministic interrupt latency and code density matter more than raw MHz. The MMC2114CFCPV33 specifically pairs this 32-bit core with industrial-grade temperature behavior and a 144-pin LQFP that exposes up to 104 general-purpose I/O lines. Key features include 256KB of in-system programmable Flash for firmware storage, 32KB of on-chip SRAM for data and stack, an integrated 33 MHz oscillator, an industrial temperature grade, and 104 programmable I/O pins. The wide peripheral set (typically including timers, PWM modules, multiple serial interfaces, and an external memory interface for the MMC2114 family) makes the part suitable for replacing legacy 8/16-bit designs that have outgrown their code space. The 144-LQFP package provides robust thermal performance and an easy-to-probe footprint for prototype bring-up. Typical applications include industrial motor control, factory automation controllers, building-automation HVAC controllers, point-of-sale terminals, medical instrumentation, and ruggedized human-machine interface (HMI) panels where the 32-bit MCore, 256KB Flash, and 104 I/O pins match the workload. The 33 MHz core clock combined with the deterministic MCore pipeline delivers consistent interrupt response for time-critical control loops. Design consideration: when migrating firmware from 8/16-bit MCUs, verify that the C compiler's MCore code-density output fits the 256KB Flash budget. The 144-LQFP land pattern requires at least a 4-layer PCB for clean GPIO fan-out, and decoupling capacitors must be placed within 5 mm of every VDD/VSS pin pair.

It is associated with the MMC2114 microcontroller family and provides 104 I/O pins according to the supplied distributor and datasheet-index data. A microcontroller is a programmable embedded-control component that combines a processor core, memory, peripherals, and I/O in one integrated circuit. The MMC2114 belongs to the MCore family of 32-bit microcontrollers and is positioned for embedded control applications requiring local program storage, digital interfaces, and deterministic control functions. Its 196-ball grid package supports dense PCB routing while exposing the device's broad pin complement on a compact board area. The verified listing identifies 256 KB of flash program memory, 32K x 8 RAM, 104 I/O, a 33 MHz operating speed, an internal oscillator, and tray packaging. The internal oscillator is relevant for designs that need a compact clocking arrangement without relying on an external frequency source. The supplied data does not provide detailed peripheral inventories, supply-voltage limits, timing values, memory-map details, or electrical characteristics, so those parameters should be confirmed in the manufacturer datasheet before schematic capture or firmware development. MMC2114 devices are associated with the legacy M210/MMC2114 microcontroller line. The product prefix MMC2114 identifies the device family, while the complete ordering code MMC2114CFCVF33 identifies the listed configuration. Because firmware compatibility, memory organization, pin multiplexing, and electrical limits are configuration-specific, engineers should treat the exact suffix and package drawing as essential parts of the selection process rather than relying only on the 33 MHz headline speed. Typical engineering uses for this device include industrial control, embedded automation, motor and power-system supervisory control, communications equipment, and test or measurement platforms. In these systems, the MCU can execute control software from its on-chip flash while using its 104 I/O pins for sensors, actuators, communication signals, and status indicators. The 196-LBGA footprint is especially relevant where a high pin count and compact assembly are more important than a large, easily hand-soldered package. For new designs, verify the exact pin assignments, power rails, decoupling requirements, programming method, reset behavior, and peripheral availability in the MMC2114 manufacturer documentation. For repair or obsolescence management, confirm lifecycle status and authorized sourcing with NXP or an approved distributor.

MOS6581

MOS6581 - 3-Voice FM Synthesizer Sound Chip | Commodore MOS | C64 Audio

The Commodore MOS 6581 (SID - Sound Interface Device) is a single-chip, 3-voice electronic music synthesizer and sound-effects generator originally designed for the Commodore 64 home computer. It combines three independently programmable analog oscillators, an analog multimode resonant filter, and per-voice ADSR envelope generators on a single NMOS die, all addressed through a memory-mapped register file compatible with the 65XX microprocessor family used in the C64, C128, and CBM-II series. A sound chip (or programmable sound generator, PSG) is a dedicated semiconductor that synthesizes audio under CPU control, sitting between the system bus and the analog output stage. SID belongs to the family of analog synthesis ICs - alongside later digital successors such as the Yamaha YM2149 and General Instrument AY-3-8910 - and is notable for being one of the first single-chip devices to combine subtractive synthesis (oscillators + filter) with programmable waveforms in a consumer computer. Key features of the MOS6581 include three independent voices each offering four selectable waveforms (triangle, sawtooth, variable-pulse, and noise), a 12-bit frequency resolution per voice, a global 4-bit volume control with four volume modes, and three analog filter modes (low-pass, high-pass, band-pass, plus notch combinations). The chip's signature warm, slightly distorted sound comes from its analog filter, which has become a defining audio characteristic of the Commodore 64 and a sought-after timbre in chiptune and electronic music production. Typical applications include the original Commodore 64/128 sound subsystem, chiptune music hardware and software synthesizers, retro-computing restoration boards, MIDI-to-SID adapter projects, and educational tools for teaching subtractive synthesis. Modern FPGA implementations such as those in the MiSTer platform reproduce the analog behavior bit-true, while the ARMSID and SIDKick Pico devices provide plug-compatible physical replacements. When designing with the MOS6581, engineers must consider that it draws power directly from the host computer's 5V and 12V rails and produces significant analog heat during operation. Replacement or refurbishment boards such as ARMSID and SIDKick Pico offer lower noise and modern reliability while retaining register-level compatibility with the original chip.

MP1720DH-12-LF-P - 2.7W Class-D Mono Amplifier | MPS
MP1720DH-12-LF-P

MP1720DH-12-LF-P - 2.7W Class-D Mono Amplifier | MPS

Monolithic Power Systems MP1720DH-12-LF-P is a 2.7 W mono Class-D low-EMI, high-efficiency audio amplifier with a full-bridge output structure, designed to drive a 4 Ω speaker and housed in a 10-MSOP-EP package. The verified manufacturer information identifies 90% efficiency, integrated 250 mΩ power MOSFETs at VIN = 3.3 V, startup/shutdown pop elimination, and short-circuit protection. A Class-D audio amplifier is a switching power amplifier that converts a low-power analog input into a differential speaker drive. The MP1720 belongs to the Class-D amplifier hierarchy, where efficiency and low electromagnetic interference are priorities for portable consumer audio. Its full-bridge topology eliminates the need for an external output coupling capacitor while maintaining the high-fidelity characteristics associated with Class-AB amplification. The principal performance features include 2.7 W output into a 4 Ω speaker, approximately 90% efficiency, and integrated 250 mΩ MOSFETs. Low-EMI operation is especially useful in compact products containing sensitive wireless, audio, or control circuitry. Startup and shutdown pop elimination improves listening behavior by reducing transient disturbances, while short-circuit protection improves fault tolerance in portable audio systems. The MP1720 architecture integrates the power stage, control electronics, and protection functions into one package. According to the Monolithic Power Systems MP1720 product page, the integrated MOSFETs have an on-resistance of 250 mΩ when VIN is 3.3 V. This integration reduces external component count and board area, although actual acoustic performance still depends on the speaker impedance, supply voltage, PCB grounding, input filtering, and output-loop layout. Typical uses include compact Bluetooth speakers, portable audio players, personal audio devices, sound bars, notification speakers, and small embedded audio modules. The 10-MSOP-EP package supports compact board layouts, while the exposed-pad construction provides a thermal path for the internal switching stage. The manufacturer specifically recommends low-voltage-coefficient tantalum, aluminum electrolytic, or suitable ceramic supply capacitors. The primary design consideration is switching-node layout. Keep the MP1720 output loop compact, provide a low-impedance ground path, place input and supply capacitors close to their associated pins, and avoid routing sensitive audio signals beneath the amplifier or switching nodes. Incorrect output filtering or capacitor selection can increase EMI and audio distortion even when the nominal 2.7 W output rating is met. This product record consolidates the verified distributor classification, manufacturer performance claims, family alternatives, and application-specific design guidance into one engineering reference. It distinguishes confirmed capabilities from specifications that still require confirmation from the complete manufacturer datasheet before a production design is released.

MP1720DH-216-LF

MP1720DH-216-LF - 2.7W Mono Class-D Audio Amplifier | Monolithic Power Systems

The Monolithic Power Systems MP1720DH-216-LF is a mono Class-D audio power amplifier that delivers 2.7 W into a 4 ohm speaker from a 2.5 V to 5.5 V supply, packaged in a 10-pin MSOP with exposed pad (MSOP-EP, MO-187BA-T). It uses a full-bridge (BTL) output structure so no output coupling capacitors are required, and it operates at up to 90% efficiency with integrated 250 mOhm power MOSFETs rated at VIN = 3.3 V. A Class-D amplifier is a switching power stage whose output MOSFETs are driven fully on and fully off, so the transistor dissipates very little power compared with a linear Class-AB stage. In the product-type hierarchy, the MP1720 sits as an audio power amplifier within amplifier ICs, inside the broader power management and signal-conditioning IC category, sitting functionally below a Class-AB or Class-AB/D hybrid amplifier. Key features include a pin-selectable 1 MHz or 1.3 MHz switching frequency or synchronization to an external clock source, an internal EMI-reduction scheme that removes the need for an output LC filter while still passing emission standards, and startup/shutdown pop elimination for clean audible start. On-chip short-circuit and thermal overload protection remove the need for external fault handling, and five fixed gain options let the designer avoid external gain-setting networks in most designs. The 20 kHz closed-loop bandwidth matches typical Class-D performance for compact speakers, while the filterless full-bridge drive reduces board area and external component count in portable audio products. The exposed pad ties to ground and carries the majority of the dissipation path, so thermal design of the PCB copper pour is the primary layout consideration. Typical applications include compact Bluetooth and portable speakers, USB-C audio dongles, notification and alert speakers in smart-home devices, headphone and game-console accessories, and small industrial or automotive auxiliary audio modules where a 2.5 V to 5.5 V rail is available. When designing around the MP1720, keep the input and decoupling capacitors close to their pins, provide adequate copper under the exposed pad, and confirm that the selected fixed-gain option matches the sensitivity of the source. Because the part is a switching amplifier, place it away from sensitive analog or RF traces to limit switching-node coupling.

MP1720DH-216-LF-P - 2.7W Class D Audio Amplifier | MPS
MP1720DH-216-LF-P

MP1720DH-216-LF-P - 2.7W Class D Audio Amplifier | MPS

The Monolithic Power Systems MP1720DH-216-LF-P is a mono Class D audio amplifier rated to deliver 2.7 W into a 4 Ω speaker from a 2.5 V to 5.5 V supply. It is packaged in a 10-pin MSOP with exposed pad and uses a full-bridge output structure. Its switching frequency can be selected as 1 MHz or 1.3 MHz or synchronized to an external clock, while an integrated EMI-reduction scheme supports low-emission operation without an output LC filter. A Class D amplifier is a switching audio amplifier that drives a speaker with a differential full-bridge waveform. This architecture places the amplifying devices in an efficient power-conversion path, allowing high output power with less heat than a conventional linear Class AB amplifier when operating near its rated load. The MP1720 family also provides startup and shutdown pop suppression, short-circuit protection, and thermal-overload protection. The verified manufacturer information identifies up to 90% efficiency, internal 250 mΩ power MOSFETs at a 3.3 V supply, five fixed-gain options, and a -40 °C to +85 °C operating-temperature range. These characteristics suit portable speakers, compact consumer audio products, and low-voltage equipment where battery efficiency, EMI control, and thermal performance are important. The exposed-pad MSOP package helps transfer heat into the PCB rather than isolating the amplifier in a thermally constrained enclosure. At the device level, the MP1720 supports a 20 kHz bandwidth, a single audio channel, and a supply voltage range of 2.5 V to 5.5 V. The -216 suffix identifies a particular fixed-gain implementation within the five-option MP1720 family. Distributor listings classify the device as a 1-channel, mono Class D amplifier and report output power as 2.7 W or 2.78 W depending on the listing convention. The switchable operating frequency is especially useful in compact audio systems because it provides flexibility between internal EMI optimization and synchronization with a shared system clock. Designers should preserve the manufacturer-recommended input, output, power-ground, and exposed-pad connections. The thermal pad must be tied to the appropriate ground plane and connected with adequate copper and vias so that heat can leave the package efficiently. The main design trade-off is that Class D switching outputs can introduce high-frequency electromagnetic energy and distortion products that require careful PCB routing. The MP1720 addresses these concerns with selectable carrier frequency, external synchronization, and integrated EMI reduction, but speaker traces, input routing, grounding, and decoupling still need disciplined implementation. This product page consolidates verified manufacturer and distributor information, package details, procurement sources, and design-oriented application guidance. It also distinguishes the confirmed family candidate from unverified cross-brand replacements so engineers can make PCB-compatibility decisions without treating merely similar audio amplifiers as drop-in parts.

The Monolithic Power Systems MP1720DH-3-LF-P is a 2.7 W mono Class-D audio amplifier capable of delivering 2.7 W into a 4-ohm speaker. The device uses a full-bridge output structure and is packaged in a 10-pin MSOP with an exposed pad. It combines high efficiency with low electromagnetic interference and supports a 1 MHz or 1.3 MHz switching-frequency selection. A Class-D audio amplifier is a switching power amplifier whose output stage rapidly switches between the supply rails. Compared with a linear Class-AB amplifier, this approach improves power efficiency because the output transistors spend more time in the low-dissipation states. The MP1720 adds EMI-reduction circuitry intended to suppress switching-related emissions without requiring an output LC filter. The MP1720 provides five fixed-gain options, selectable according to the MP1720 ordering information, and the -3 variant identifies one of those gain configurations. Its switching frequency can be selected between 1 MHz and 1.3 MHz using a control pin or synchronized to an external clock source. These features support compact speaker designs where radiated emissions, audible artifacts, and supply-rail noise must be controlled simultaneously. Internally, the full-bridge topology develops a differential speaker drive, removing the need for a DC-blocking output capacitor when the amplifier operates in Bridge-Tied-Load configuration. Short-circuit and thermal-overload protection are specified for the device. The exposed pad provides a thermal path from the amplifier to the PCB, making copper-pour area and thermal via layout important during continuous high-power playback. Typical uses include portable speakers, consumer audio accessories, voice-enabled devices, sound bars, and compact Bluetooth speaker systems. It is particularly suitable where a 4-ohm load and moderate output power are required without introducing the heat and idle power associated with a Class-AB output stage. An external input coupling, output filtering, and speaker interface may still be required according to system-level EMI and safety requirements. Designers should verify the -3 gain setting against the source impedance and preamp architecture, reserve sufficient input and output capacitors close to the device, and connect the exposed pad to a low-impedance ground plane. When radiated-emission testing fails, switching-frequency adjustment or synchronization should be evaluated before adding an output filter. This page combines the verified distributor identity, the manufacturer MP1720 family information, package-level comparison data, same-family alternatives, and practical Class-D layout guidance. It is intended to help engineers identify sourcing, electrical-fit, and layout implications beyond the basic distributor listing.

The MP1720 family provides selectable 1 MHz or 1.3 MHz switching frequencies and can be synchronized to an external clock source. Its integrated 250 mΩ power MOSFETs reduce external component count, while startup and shutdown pop elimination improves listening experience. The -9 suffix identifies the family's fixed-gain ordering option. Short-circuit and thermal-overload protection support robust operation in compact audio products. The MP1720DH-9-LF-Z can deliver 2.7 W into a 4 Ω speaker. A listed source also reports 2.78 W output power, reflecting a rounded or differently stated test condition. Its 20 kHz bandwidth and low-EMI design make it suitable for audio products requiring compactness and reduced filter requirements, although actual distortion, thermal performance, and output power must be checked against the manufacturer's test conditions. Typical uses include portable speakers, consumer audio accessories, compact soundbars, call-system speakers, and other low-voltage mono audio loads. The 10-MSOP exposed-pad package requires careful PCB layout for heat transfer, and the exposed pad must be connected to ground according to the manufacturer's land pattern and datasheet instructions. A key design consideration is the relationship between supply voltage, speaker impedance, and heat dissipation. Although Class-D topology improves efficiency, output-stage losses still become heat in the exposed pad. Place input, output, ground, and decoupling connections for low-loop-area routing, while using the recommended switching frequency to balance EMI, filtering, and thermal performance. This page combines manufacturer specifications, distributor availability, family-level drop-in alternatives, comparison data, and practical layout guidance.

MP1720DQ-216-LF-P - 2.7W Mono Class-D Amplifier | MPS

Monolithic Power Systems MP1720DQ-216-LF-P is a 2.7 W mono Class-D audio amplifier with a full-bridge output, capable of delivering 2.7 W into a 4 Ω speaker while providing approximately 90% efficiency in a 10-QFN (3 x 3 mm) package. The amplifier integrates 250 mΩ power MOSFETs at VIN = 3.3 V and includes startup and shutdown pop elimination, short-circuit protection, and low-EMI operation. A Class-D amplifier is a switching audio-output stage whose transistor network continuously drives the speaker load. Its class hierarchy is Class-D amplifier → audio power amplifier → amplifier IC → analog and power-management semiconductor. Unlike a conventional linear Class-AB output stage, the MP1720 converts supply energy into audio output more efficiently, reducing heat and allowing a compact solution for portable and embedded speakers. The verified manufacturer information identifies the MP1720 family as a high-efficiency, low-EMI Class-D audio amplifier. Its full-bridge topology supports a 2.7 W output into 4 Ω, while the stated 90% efficiency helps lower power consumption and board-space requirements. Integrated 250 mΩ MOSFETs at a 3.3 V supply reduce the need for external output power devices, and the available protection and pop-elimination features support practical speaker interfaces. The MP1720DQ-216-LF-P is identified by distributors as a one-channel mono Class-D amplifier in a 10-QFN package measuring 3 x 3 mm. A QFN package places leadless terminals around the perimeter and can use an exposed thermal pad.

Typical uses include compact speaker drivers in portable consumer equipment, personal audio products, mobile accessories, embedded control systems, and small industrial or automotive accessories where a 2.7 W mono output is sufficient. The BTL full-bridge output allows the amplifier to drive a speaker without a conventional output coupling capacitor when configured according to the manufacturer recommendations. The exact input filter, gain-setting method, output-filter requirements, and maximum supply voltage must be confirmed from the manufacturer datasheet before layout. For implementation, use the manufacturer-recommended input and output filtering network, place the amplifier close to the speaker connection, and provide adequate exposed-pad copper for thermal dissipation. EMI performance depends on correct grounding, short output routing, controlled input impedance, and proper filter placement. Verify speaker impedance and power limits during prototype testing because an incorrect load or filter implementation can increase distortion, heat, or radiated emissions. This product page consolidates verified manufacturer and distributor information for the MP1720DQ-216-LF-P, adds practical engineering guidance, and explicitly separates confirmed facts from parameters that still require datasheet confirmation. It also documents the absence of a verified, pin-compatible substitute rather than presenting unverified cross-brand parts as drop-in replacements.

MP1720DQ-3-LF-P - 2.7W Class-D Mono Amplifier | MPS

The Monolithic Power Systems MP1720DQ-3-LF-P is a 2.7 W mono Class-D audio amplifier that uses a full-bridge output structure to drive a 4 Ω speaker. The verified manufacturer and distributor results identify a surface-mount 10-QFN package measuring 3 mm by 3 mm, along with integrated 250 mΩ power MOSFETs operated from a 3.3 V supply. The device combines switching-class efficiency with the high-fidelity character associated by the manufacturer with a Class AB amplifier. A Class-D audio amplifier is a power-management semiconductor that converts an analog audio input into a high-frequency switching output capable of driving a loudspeaker efficiently. Within the broader hierarchy, it is an audio amplifier IC, a power-management IC, and a semiconductor. Unlike a conventional linear Class AB output stage, the MP1720 uses a switching full-bridge architecture, reducing the amount of power dissipated as heat while delivering audio energy to the speaker. The MP1720 integrates the 250 mΩ power MOSFETs, startup and shutdown pop-elimination circuitry, and short-circuit protection. According to the Monolithic Power Systems MP1720 product result, these functions allow a compact audio-output solution with reduced external component count. The stated 90% efficiency is especially relevant in portable audio products where amplifier dissipation directly affects battery life and enclosure temperature. The exact efficiency conditions, thermal ratings, and protection thresholds require confirmation from the manufacturer datasheet. The full-bridge output can drive a single 4 Ω speaker at up to 2.7 W. Because the output is bridge-tied, the speaker receives the differential voltage generated between the two output nodes. Designers must keep the BTL speaker wiring isolated from system ground and should use a speaker return path that satisfies the requirements of the application. Feedback and input filtering details should be implemented with the component values and topology shown in the official MP1720 documentation. Typical uses include compact Bluetooth speakers, portable speakers, sound bars, consumer audio modules, and other low-voltage embedded audio products. The 3.3 V supply and 2.7 W output rating align well with battery-powered equipment whose speaker impedance is 4 Ω. A system requiring higher output power, a different supply voltage, stereo operation, or a different pinout should not be treated as a direct replacement without a complete electrical comparison. The primary design considerations are exposed-pad layout, input and output filtering, speaker return routing, thermal performance, and startup behavior. Place the device close to the speaker connector to minimize switching-node trace length, and provide a continuous low-impedance ground plane around the exposed pad. Decoupling and passive-component values must be confirmed against the official datasheet and typical application circuit. This page separates verified MP1720DQ-3-LF-P facts from unverified details.

The device is designed to drive a 4-ohm speaker while combining Class-D efficiency with Class-AB-like audio fidelity. Its low-EMI architecture, integrated protection, and compact footprint support portable audio, consumer audio, and compact speaker applications. A Class-D audio amplifier is a switching-based amplifier that converts a low-level analog input into a high-frequency pulse-width-modulated output. Its full-bridge output stage applies differential voltage to the speaker, increasing usable output voltage and efficiency. In the broader hierarchy, this MP1720 belongs to the amplifier-IC category within integrated circuits and provides a more efficient speaker-drive solution than a conventional linear Class-AB output stage. The MP1720 delivers up to 2.7 W into a 4-ohm speaker while maintaining an efficiency of approximately 90%. Its integrated power MOSFETs have an on-resistance of 250 milliohms when operated from a 3.3 V supply, reducing conduction loss in compact systems. The low-EMI design is intended to simplify coexistence with sensitive analog, radio, or digital circuitry. Startup and shutdown pop-elimination circuitry further improves the listening experience during power transitions. The integrated feature set includes short-circuit protection, thermal protection, and depop circuitry. These protections are important in portable and consumer products where a speaker cable fault, restricted enclosure, or sudden power transition can otherwise damage the amplifier or produce unwanted noise.

Typical uses include portable speakers, Bluetooth speaker accessories, compact consumer audio products, USB-powered audio systems, and small alarm or notification devices. In a 4-ohm speaker design, the MP1720 provides substantially more output power than a conventional low-power analog headphone amplifier. Its 90% efficiency also reduces the power drawn from a battery or USB supply compared with a linear amplifier operating at a similar output level. PCB design should preserve the manufacturer’s recommended input, supply, and filtering networks, provide a low-impedance ground path, and maintain adequate thermal copper beneath the package. Because Class-D output stages contain high-frequency switching energy, output routing should remain short and isolated from sensitive input or clock signals. Verify the loudspeaker load, supply limits, thermal conditions, and output-filter requirements before production release. This product record combines the verified manufacturer specifications, distributor listings, lifecycle information, package data, and available replacement information. It also identifies where pricing and detailed pin-level data were not available, preventing unverified assumptions from being presented as guaranteed design values.

MP1740EC-LF-P - 3W Mono Class-D Amplifier | MPS

Monolithic Power Systems MP1740EC-LF-P is a 3 W high-efficiency mono Class-D audio amplifier with a 91% efficiency rating and a 9-WLCSP package measuring 1.55 mm by 1.55 mm. It uses a full-bridge output structure to drive 4-ohm speakers and provides 2 V/V gain. The device is designed for compact audio systems where high output efficiency, small size, and direct speaker drive are important. A Class-D audio amplifier is a switching power amplifier that uses a full-bridge H-bridge output to deliver energy to a speaker. Compared with a linear Class-AB amplifier, its Class-D topology can reduce amplifier power loss and improve operating efficiency. The MP1740 combines that efficiency with the audio fidelity associated with Class-AB operation, while its 2 V/V default gain can be changed by selecting different input resistors. The principal verified features include 3 W output into a 4-ohm speaker, 91% efficiency, mono Class-D operation, a full-bridge output, and a 1.55 mm by 1.55 mm WLCSP package. The manufacturer page identifies the MP1740 as a low-power mono BTL Class-D audio amplifier and identifies EV1740EC-00A as its evaluation board. These characteristics make the device suitable for portable speakers, compact consumer audio, and embedded audio products. Because the MP1740 uses a BTL output, the speaker connections are not referenced to ground in the same way as a conventional single-ended amplifier. PCB layout, speaker impedance, input filtering, supply decoupling, and thermal performance must be reviewed against the manufacturer documentation. The 1.55 mm by 1.55 mm WLCSP also requires assembly capability and careful land-pattern design. Typical designs place the amplifier near the speaker connector, connect the differential Class-D outputs to the speaker, and bypass the supply close to the device. The amplifier's 91% efficiency means less power is dissipated internally than with a comparable linear amplifier at the same stated operating point, but speaker loading and supply conditions still determine actual thermal and acoustic performance. The MP1740 is therefore most appropriate when a compact, efficient, mono speaker drive solution is required. This page combines the verified manufacturer and distributor descriptions with practical design guidance, comparison fields, procurement context, and application-oriented engineering information.

MP2736DQG-LF-P - 450mΩ Dual SPDT Analog Switch | MPS

The Monolithic Power Systems MP2736DQG-LF-P is a low-voltage, 450 mΩ dual single-pole double-throw monolithic CMOS analog switch operating from 1.65 V to 5.5 V in a 10-QFN package measuring 1.4 mm by 1.8 mm. It provides two 2:1 switch circuits with bidirectional signal paths, low-power operation, fast switching, and glitch-free behavior. An analog switch is an integrated semiconductor device that routes signals between circuit nodes under digital control. The SPDT topology connects one common terminal to one of two selectable terminals, allowing one signal source to be steered between two destinations. A dual SPDT switch contains two independently controlled 2:1 paths. Within the device hierarchy, the MP2736DQG-LF-P is an analog switch IC, a member of the broader interface IC category used for signal routing and multiplexing. Key features include a low on-resistance of 450 mΩ, a single-supply operating range of 1.65 V to 5.5 V, and a specified operating temperature range from -40°C to +85°C. The MP2736 family combines low power consumption, high switching speed, low on-resistance, and a small package. Its two switching circuits and common enable architecture suit compact portable and battery-powered equipment where PCB area and supply current are important constraints. The MP2736 is implemented as a monolithic CMOS analog switch, allowing low-voltage operation and efficient signal routing. Switching times of 35 ns and 36 ns are specified in the verified product information, supporting applications that cannot tolerate lengthy transition intervals. The available bandwidth reaches 50 MHz, while the 130 pF value identifies the relevant capacitance specification from the supplied source data. Because the switch is bidirectional, it can route signals in either direction when the electrical operating conditions remain within the device limits. Typical uses include battery-powered audio routing, portable test and measurement interfaces, communication-signal multiplexing, sensor-path selection, and general analog signal switching. The 10-QFN package provides a practical footprint for dense portable systems, while the 1.65 V to 5.5 V range covers common low-voltage rails. In each case, the design must account for signal amplitude, switching duration, off-state behavior, and the exact enable polarity and timing required by the application. A key design consideration is that low on-resistance does not eliminate all analog-switch limitations. Board leakage, connector resistance, and trace resistance can dominate a 450 mΩ path, while capacitive loading can influence switching performance. Designers should minimize sensitive traces, use a continuous ground reference, and verify signal integrity with the actual source impedance, load, supply voltage, and enable sequence before production release. This page consolidates verified manufacturer and distributor information, parameter comparisons, procurement context, and practical design guidance for engineers evaluating the MP2736DQG-LF-P as a low-voltage, low-resistance dual SPDT analog switch.

The manufacturer identifies the MP2735/MP2736 family as suitable for portable and battery-power applications where analog signal routing must be compact and power efficient. The MP2736 uses an EN control input. According to the manufacturer datasheet information, all switches are placed in a high-impedance state when EN is high. This global enable behavior provides a defined off condition for both SPDT channels and can simplify system-level control when analog paths must be isolated. The dual SPDT arrangement supports selecting one of two signal sources per channel or routing a signal to one of two destinations, depending on the surrounding circuit topology. The 450 mOhm on-resistance specification is the key low-voltage analog switching parameter identified in the verified distributor listings. Lower on-resistance helps reduce signal attenuation and improves source-to-load drive capability, while the 1.65 V to 5.5 V operating range allows operation from a single low-voltage supply. The 10-QFN package is particularly useful in portable equipment where board area is constrained. The -Z ordering suffix is supplied in tape-and-reel packaging according to distributor product information. Typical applications include battery-powered sensor interfaces, portable measurement systems, audio routing, communication equipment, and compact analog signal-conditioning circuits. The EN pin can be used for power-down or signal-isolation control. Designers should verify the exact pin names, logic levels, switch configuration, and timing behavior against the MP2736 datasheet before finalizing a PCB layout. This page combines the verified manufacturer and distributor information with practical selection guidance, package details, and design considerations. It is intended to help engineers identify whether the MP2736DQG-LF-Z is suitable for a low-voltage analog-routing design and to distinguish it from unrelated switch functions or package-incompatible alternatives.

MP7720DP-LF - 20W Mono Class-D Audio Amplifier | MPS

Monolithic Power Systems MP7720DP-LF is a 20 W mono Class-D audio amplifier with a 9.5 V to 24 V supply range, single-ended output, and an 8-pin PDIP package. It integrates 180 mΩ power MOSFETs, startup and shutdown pop-elimination circuitry, short-circuit protection, and mute or standby control to reduce external circuitry and board area. A Class-D audio amplifier is a switching power amplifier in an audio-signal hierarchy. Its output-stage transistors operate mainly in a switching state, allowing efficient power delivery compared with a traditional linear amplifier. The MP7720 uses a single-ended output structure intended for driving a mono speaker load and integrating the power stage, control functions, and protection features into one device. The principal verified ratings are 20 W output power, a 9.5 V minimum supply voltage, a 24 V maximum supply voltage, and an operating temperature range of -40 °C to 85 °C. The package is a lead-free plastic 8-DIP package, also identified in the supplied data as PDIP-8. The verified distributor listing describes the product as a 20 W Class-D mono single-ended audio amplifier. The integrated 180 mΩ power MOSFETs are intended to improve amplifier efficiency and reduce solution size. Startup and shutdown pop-elimination circuitry helps reduce audible clicks during state changes, while short-circuit protection adds a basic safeguard for the output stage. Mute and standby functionality supports controlled audio muting or power management, although exact timing, enable thresholds, and output-current limits require confirmation in the manufacturer datasheet. Typical applications include compact mono speakers, portable audio equipment, consumer audio products, small powered speaker systems, and auxiliary audio modules. The 9.5 V to 24 V supply range supports systems using higher-voltage audio rails, while the through-hole PDIP package can simplify prototype assembly and manual installation. Designers must still verify speaker impedance, power derating, thermal conditions, supply decoupling, and output filtering against the manufacturer data before production use. This product summary combines the verified manufacturer description, distributor specifications, package information, and engineering notes to support initial design selection. It does not replace the complete MP7720 datasheet, particularly for electrical limits, pin functions, thermal resistance, switching behavior, and application-specific compensation.
