MKL46Z256VLL4

MKL46Z256VLL4 - 48MHz Cortex-M0+ MCU, 256KB Flash, USB, LCD | NXP

The NXP Semiconductors MKL46Z256VLL4 is an ultra-low-power ARM Cortex-M0+ microcontroller in the Kinetis KL4x sub-family, delivering up to 48 MHz core performance with 256 KB of flash and 32 KB of SRAM in a 100-pin LQFP (14x14 mm) package. The part integrates a full-speed USB 2.0 device controller, a segment LCD controller with up to 8x40 segments, multiple low-power modes including a new compute mode, and a rich set of analog and digital peripherals for portable and battery-powered designs. A Cortex-M0+ microcontroller is an entry-level 32-bit ARM core optimized for energy efficiency and deterministic interrupt handling in embedded systems. It sits below the Cortex-M3/M4 in the ARMv6-M hierarchy and is widely adopted in cost-sensitive applications such as electronic scales, flow meters, smart thermostats, wearable health monitors, and IoT sensor nodes where every microamp of quiescent current and every dollar of silicon matters. Key features of the MKL46Z256VLL4 include 50 uA/MHz typical run-mode current, sub-uA deep-sleep modes, a 12-bit SAR ADC, 16-bit timers, DMA, I2C, SPI, UART, low-power UART, and an integrated segment LCD driver that eliminates the need for an external LCD bias generator. The full-speed USB device interface enables charging port and data-logging applications. The 100-LQFP package provides ample GPIO for segment-LCD designs while remaining hand-solderable for prototypes. From an architectural standpoint, the KL46 silicon pairs the Cortex-M0+ core (ARMv6-M, Thumb/Thumb-2 instruction set) with a tightly-coupled low-leakage SRAM and a flexible peripheral bridge. The new compute mode allows the CPU to wake briefly, perform signal processing, and return to a deep retention state, reducing dynamic power by placing peripherals in an asynchronous stop state. The 256 KB flash supports both DFlash-style EEPROM emulation and on-the-fly firmware updates. Typical applications span battery-powered metering, electronic shelf labels, consumer health devices, USB charging and data cables, HVAC thermostats, industrial flow meters, and entry-level wearables. The combination of USB device, segment LCD, and ultra-low-power compute mode makes the MKL46Z256VLL4 a strong fit for handheld, mains-free devices where battery life, BOM cost, and display integration are simultaneously critical. A key design consideration is the external supply decoupling network and segment-LCD bias capacitor network: a 4.7 uF bulk plus 100 nF per supply pin is recommended, and the LCD_VLL1/VLL2/VLL3 charge-pump caps must be sized per the datasheet to avoid ghosting on high-segment-count displays. The 100-LQFP exposes up to 84 GPIO, with many pins shared between LCD segment lines and digital peripherals, so pin mux planning is essential. This page consolidates Kinetis family data, drop-in package-compatible Kinetis alternatives, and design notes beyond the manufacturer datasheet, intended as a working reference for embedded engineers evaluating this MCU.

It is positioned by NXP as the entry point of the Kinetis V series for real-time motor control. A microcontroller (MCU) is a single integrated circuit that combines a processor core, program memory (flash), data memory (SRAM), and a rich set of peripherals in one package. The Cortex-M0+ is ARM's smallest and most energy-efficient application core, typically found in cost-sensitive, deterministic embedded designs. Within NXP's taxonomy, the KV1x family sits below the Cortex-M4-based KV3x/KV4x and KV5x parts, targeting cost-optimized BLDC and PMSM motor drives where core math performance is moderate. Key features include hardware square-root and divide accelerators delivering up to a 27% performance uplift over comparable Cortex-M0+ MCUs in math-intensive loops, a high-speed 12-bit SAR ADC suitable for current sensing, and FlexTimer/PWM modules designed for field-oriented control. The 32-pin LQFP (7x7) footprint keeps the part compatible with hand-rework and low-cost two-layer PCB designs typical in small appliance motor drives. A single 2.7V-5.5V supply is supported, matching common 3.3V and 5V bus rails. Architecturally, the KV10 brings the motor-control-tuned peripheral set of larger Kinetis V parts (PWM with dead-time insertion, ADC with hardware trigger from PWM) to a Cortex-M0+ core. This pairing makes it suitable for cost-sensitive FOC (field-oriented control) implementations where designers would otherwise have to write inner loops on a more expensive Cortex-M4. Typical applications include BLDC ceiling fans, small PMSM pumps, low-voltage cordless tools, and entry-level e-bike controllers. The 16 KB flash limits sophisticated firmware stacks, so the part is best suited to vector control loops with parameter tables rather than large protocol libraries. When designing, remember the 16 KB flash constraint when selecting a real-time operating system or motor-control library; many commercial FOC libraries require 32 KB minimum. Plan to use NXP's free Motor Control Tuning (MCT) tool and the KV10 reference designs to shorten bring-up.

MM74C948N - 8-Bit ADC w/ 16-Ch MUX | Texas Instruments | DIP-40

The Texas Instruments MM74C948N is an 8-bit CMOS analog-to-digital converter with a built-in 16-channel analog input multiplexer, housed in a 40-pin PDIP (N) through-hole package. Operating from a single 5 V supply over an industrial -40C to +85C temperature range, it features a successive-approximation register (SAR) architecture with a maximum conversion time of 116 us, making it suitable for microprocessor-controlled data-acquisition systems. A SAR ADC (Successive-Approximation Register Analog-to-Digital Converter) is a type of data converter that converts an analog input voltage into a digital code by iteratively comparing the input against an internal DAC. The 8-bit SAR architecture is widely used in embedded and industrial designs because it offers deterministic conversion latency, low power consumption, and ease of interface to microprocessors - in the component taxonomy it sits between sigma-delta ADCs (higher resolution, slower) and flash ADCs (faster, lower resolution), with the MM74C948N targeting moderate-speed multi-channel acquisition. The MM74C948N combines an 8-bit ADC core with an analog input multiplexer (up to 16 single-ended analog inputs), eliminating the need for external analog switches in multi-sensor systems. It supports microprocessor-compatible interface logic and operates from a single 5 V supply, simplifying integration with 5 V CMOS logic families. Industrial-grade temperature tolerance (-40C to +85C) supports factory automation and process-control environments. Designed in CMOS technology, the MM74C948N achieves low power consumption compatible with battery-powered and portable instrumentation. The integrated 16-channel input mux eliminates the need for an external analog switch array, reducing BOM cost and PCB area while preserving the 8-bit conversion accuracy of the ADC core. Successive-approximation conversion delivers deterministic conversion timing, simplifying real-time software design. Typical applications include industrial process control and multi-sensor data acquisition, portable digital-panel meters, factory automation front-ends, environmental monitoring systems, and microprocessor-based instrumentation. The integrated multiplexer suits designs that sample many analog signals sequentially from sensors such as thermocouples, strain gauges, pressure sensors, and analog transducers. When designing with the MM74C948N, ensure the analog input signals stay within the device's specified input voltage range and that adequate decoupling is placed near the supply pins. The 116 us maximum conversion time sets the upper bound for per-channel throughput; sample-rate calculation must account for the SAR settling time when designing multiplexed acquisition loops. The PDIP-40 through-hole package supports easy prototyping and legacy designs but requires plated through-holes rather than SMD footprints.

MM74C949N

MM74C949N - 8-Bit Microprocessor-Compatible ADC, 28-PDIP | TI

The Texas Instruments MM74C949N is a monolithic CMOS 8-bit microprocessor-compatible analog-to-digital converter (ADC) with an on-chip 8-channel analog multiplexer, housed in a 28-pin plastic DIP (28-PDIP) package and operating from a single +5 V supply. Per the manufacturer datasheet, the device delivers a successive-approximation conversion with an 8-channel analog input MUX, providing a single-chip data-acquisition front end for microprocessor-based systems. Key headline parameters include 8-bit resolution, an 8-channel single-ended multiplexer, a 5 V supply requirement, and 116 microseconds typical total conversion time. The CMOS construction yields low power consumption suitable for battery-instrumented and industrial control systems. What is an 8-bit ADC with multiplexer? An analog-to-digital converter transforms a continuous analog voltage into a discrete digital code; an 8-bit converter provides 256 quantization levels (LSB = FS/256). Adding an integrated analog multiplexer allows one ADC to sequentially digitize several analog sources, replacing multiple single-channel converters and reducing both board area and cost. MM74C949N belongs to the category hierarchy: ADC -> data converter -> data acquisition IC -> mixed-signal semiconductor, and integrates a successive-approximation register (SAR) architecture with CMOS logic and a tri-state output latch for direct connection to 8-bit microprocessors. Differentiating features include built-in sample-and-hold, software-configurable channel selection, and a microprocessor-compatible control interface that simplifies handshaking. The 8-channel input MUX is software-addressable, while the tri-state output buffer allows the ADC to share a data bus with other peripherals. Internal reference and clock generation minimize external component count, and the CMOS process delivers low quiescent current draw, suiting battery-powered or remote instrumentation. Operating temperature spans -40 C to +85 C, supporting industrial and commercial environments. Architecture-wise, the device uses a successive-approximation register driven by an internal RC oscillator to perform a binary search against the analog input. The 8-channel analog MUX is constructed from CMOS transmission gates, and a sample-and-hold capacitor holds the input during conversion. The digital interface generates standard microprocessor read/write handshake signals so the part can connect directly to an 8-bit data bus without glue logic. Typical applications include industrial process-control data acquisition boards, portable battery-powered instrumentation, multiplexed sensor monitoring in HVAC and environmental systems, automotive sensor interface subsystems, and microprocessor-based measurement front-ends. The integrated MUX is particularly useful when more than one analog source (temperature, pressure, flow, level) must be digitized by a single MCU. When designing with MM74C949N, ensure the analog input remains within the supply rails and that input source impedance is low enough to charge the internal sample-and-hold capacitor within the acquisition window. Add 0.1 microfarad decoupling close to the supply pin, and provide anti-alias filtering on each MUX channel.

MM74HC573WMX - 3-STATE Octal D-Type Latch | onsemi

The onsemi MM74HC573WMX is a high-speed 3-STATE octal D-type latch built with silicon-gate P-well CMOS technology and supplied in a 20-pin SOIC package. It provides eight transparent D inputs, eight non-inverting Q outputs, a common latch enable, an active-low output enable, and 3-STATE bus outputs capable of driving 15 LS-TTL loads. These characteristics make it suitable for bus-interface, buffering, and register applications. An octal D-type latch is a level-sensitive storage element: while its enable input is active, the Q outputs follow the corresponding D inputs; when the enable is inactive, the last presented data level is retained. The 3-STATE output control allows each output to be driven, placed in a high-impedance state, or otherwise controlled for shared-bus use. The MM74HC573WMX therefore belongs to the broader CMOS logic family, specifically latches and bus-interface logic. Key features include low power consumption, high noise immunity, and output-drive capability for 15 LS-TTL loads. The transparent architecture supports data transfer when the latch-enable timing is controlled externally. The output-enable function is useful for preventing multiple devices from driving a shared data bus during multiplexing or address-latch applications. Exact propagation-delay, supply-voltage, and current limits should be confirmed against the manufacturer datasheet for the selected operating conditions. The MM74HC573WMX is commonly used where an eight-bit parallel data path must be temporarily latched or isolated. Typical implementations include address or data-bus buffering, microprocessor and microcontroller interface logic, temporary data storage between parallel buses, and general-purpose digital control systems. The 20-pin SOIC package supports conventional surface-mount PCB assembly, while the latch and output-enable signals provide sequencing control. When designing around this device, treat enable and output-enable timing as part of the system interface. Ensure that bus contention is prevented during output-disable transitions, account for load capacitance when timing is critical, and use pull-up or pull-down arrangements where required by the surrounding bus architecture. The manufacturer datasheet and device-specific timing tables are the authoritative references for final design decisions. This product page combines verified source information, package and functional context, comparison criteria, and practical design guidance. It is intended to help engineers identify suitable applications and confirm whether the MM74HC573WMX is appropriate for a particular bus-interface or logic design.
