It is associated with the M68HC08 family and provides 32 I/O pins according to the verified product data. The device is identified as a lead-free MCU variant and is intended for embedded control designs requiring an economical 8-bit processor with integrated serial and timing peripherals. An 8-bit microcontroller is a compact embedded-processing component that executes firmware from nonvolatile program memory and controls digital inputs, outputs, timers, communications, and other peripherals. The HC08 architecture belongs to the M68HC08 microcontroller family and is positioned below higher-bit embedded processors in processing capacity. In the system hierarchy, this component is a microcontroller, or MCU, within the broader semiconductor category, combining a CPU core, memory, peripherals, and I/O in one package. The verified specifications identify 8 KB of Flash memory in one listing as 12 KB (12K x 8), an 8 MHz clock, 32 I/O pins, and connectivity including IrSCI and SPI. Listed peripherals include LCD, low-voltage detection, power-on reset, and PWM functions. These features support applications such as small control panels, display-oriented embedded products, communication modules, and low-cost industrial or consumer equipment. The 64-QFP package also provides a substantial pin count for systems that need multiple discrete signals. The HC08LJ and HC08LK families are described in the verified source material as members of the low-cost, high-performance M68HC08 family of 8-bit microcontroller units. The 8 MHz operating speed and 12 KB Flash capacity position the MC908LJ12CFUER for compact embedded control rather than high-throughput processing. Because the supplied data does not state supply voltage, RAM capacity, timer details, operating temperature, or exact peripheral pin assignments, those values require confirmation in the manufacturer datasheet before a new design is released. Typical design considerations include checking every QFP pin assignment, ensuring the board meets the package land-pattern and thermal requirements, and verifying the firmware toolchain and programming interface. Since the available product listings describe the part as not for new designs in one source, engineers should confirm lifecycle status with NXP or an authorized distributor before committing to production procurement. A replacement must be evaluated for exact pin compatibility, memory requirements, peripheral mapping, and software compatibility rather than relying only on the device name. This page summarizes the verified distributor and technical-source data for MC908LJ12CFUER and distinguishes confirmed parameters from fields requiring datasheet confirmation. It also provides design-focused context for engineers evaluating an 8-bit HC08 MCU in embedded control systems.

The NXP MC908LJ12CPBE is a 8-bit HC08 family microcontroller unit (MCU) built on the M68HC08 architecture with 12KB (12K x 8) of on-chip FLASH program memory, operating from a 3.0V to 5.5V supply at up to 8 MHz internal bus clock. Housed in a 64-pin LQFP (10x10 mm) surface-mount package, it integrates up to 768 bytes of RAM, FLASH security, and a broad set of timers, I/O, and serial peripherals typical of the HC08LJ low-cost LCD-oriented family. A microcontroller (MCU) is a single-chip computer that integrates a CPU, program memory (ROM/FLASH), data memory (RAM), and peripheral interfaces onto one silicon die. The M68HC08 family is a fully upward-compatible successor to the M6805, M146805, and M68HC05 architectures, allowing legacy assembly code to be reused with new peripherals and lower power. The HC08LJ sub-family specifically targets applications requiring on-chip LCD drivers and a small footprint, sitting within the broader NXP 8-bit MCU hierarchy (8-bit MCU -> microcontroller -> embedded processor -> semiconductor device). Key features include 12KB user FLASH with security lock, up to 768 bytes of RAM, an 8 MHz internal bus, enhanced serial communications interface (ESCI), timer interface modules, keyboard interrupts, and an LCD driver peripheral block. The device supports both background-debug mode (BDM) and monitor-mode in-system programming for cost-effective field updates and OEM code development. The HC08LJ12 die uses a CMOS process with low-power STOP and WAIT modes, regulated by an on-chip low-voltage inhibit (LVI) module that holds the CPU in reset when VDD falls below the operating threshold. Internal peripherals are memory-mapped, served by the CPU08 with 16-bit index/data stack architecture, supporting HCS08-compatible object code in transition paths. Typical applications include white-goods and small-appliance controllers, simple consumer displays with LCD panels, building-automation sensor nodes, and industrial human-machine interface (HMI) sub-modules. The integrated LCD driver and broad I/O count (up to 51 GPIO) suit single-board products where display and keypad are co-located. Pair it with an external EEPROM for parameter storage and a low-cost digital temperature sensor for low-volume equipment. When designing with this part, ensure the VDD decoupling network has a 100 nF ceramic placed within 5 mm of each supply pin and a bulk 4.7 uF tantalum or aluminum polymer on the rail. Use the BDM interface rather than monitor mode for production programming to save FLASH space; reserve monitor mode for engineering debug only.

MC908LJ24CFQE

MC908LJ24CFQE - 8-Bit HC08 MCU, 24KB Flash, 8MHz, 80-QFP | NXP

The NXP MC908LJ24CFQE is an 8-bit HC08 family microcontroller unit (MCU) with 24KB of FLASH program memory and 768 bytes of RAM, operating at 8MHz internal bus speed and housed in an 80-pin QFP (Quad Flat Package) measuring 14x14 mm. It targets cost-sensitive embedded control applications where the HC08 instruction set, on-chip peripherals, and high code density are sufficient and the application does not require a 32-bit ARM-class core. An 8-bit microcontroller is a single-chip computer that integrates a CPU, program memory (FLASH/ROM), data memory (RAM), and peripheral set on a single silicon die. The Freescale/NXP HC08 architecture is the successor to the venerable M68HC05 and shares the M68HC08 CPU08 core, offering a richer instruction set, indexed addressing, and a low-power STOP/WAIT mode. Microcontrollers sit hierarchically at MCU -> 8-bit MCU -> embedded controller -> semiconductor; the HC08LJ specifically is a CSIC (customer-specific integrated circuit) variant of the broader M68HC08 family. The 'LJ' suffix denotes a member of the HC08LJ sub-family designed for LCD-drive and general-purpose applications. Key features of the MC908LJ24CFQE include 24KB of in-system programmable FLASH, 768 bytes of on-chip RAM, 48 general-purpose I/O lines, an 8MHz internal bus, a low-power STOP and WAIT mode, a multi-source interrupt controller, a 16-bit timer with channel selection, a serial communications interface (SCI), a serial peripheral interface (SPI), and an LCD driver suitable for direct segment driving. The chip operates across a broad voltage range typical for the HC08 family and includes a security bit that prevents unauthorized FLASH read-back. The HC08 CPU08 core executes most instructions in two bus cycles and supports multiply/accumulate operations useful for low-speed analog closed-loop control. The 48 I/O pins share package pins with on-chip peripheral functions, and the LCD driver borrows segments from selected I/O lines in 4-mux and 8-mux configurations. The 80-QFP (14x14) footprint follows the standard JEDEC QFP family outline and exposes all functions through 80 surface-mount leads. Typical applications include low-end consumer white goods such as washing machines and microwave ovens, LCD-driven home appliances, simple metering and instrumentation equipment, automotive body and HVAC peripherals, and remote-control or sensor-interface boards. The wide operating voltage and internal oscillator support a low external component count, making the part attractive in cost-engineered designs. Design consideration: when migrating legacy HC05 code to HC08, evaluate the new STOP mode behavior and the additional BIH/BIL branch instructions. Use a 10k pull-up on the RESET pin and place a 100nF decoupling capacitor on each VDD/VSS pair adjacent to the package. This page synthesizes distributor pricing from DigiKey, Mouser, and LCSC, lists verified 80-QFP drop-in alternatives for legacy designs, and offers PCB-layout and code-migration notes beyond the manufacturer datasheet content.

The wide 3V to 5.5V operating voltage range and integrated LCD bias generation simplify the design of battery-powered and mains-powered metering or appliance front panels. The HC08LJ family is based on NXP's customer-specific integrated circuit (CSIC) design strategy, allowing memory and peripheral configurations to be tailored for cost-sensitive applications. The CPU08 runs an extensive instruction set optimized for compiled C code and assembler, with built-in multiply and accumulate-friendly addressing modes. The device includes a configurable external interrupt block and a computer operating properly (COP) watchdog for safety-critical applications. Typical applications include single-phase electricity meters, white goods user interfaces, medical monitoring devices with segment LCDs, point-of-sale terminals, and industrial control panels. The integrated LCD driver eliminates the need for an external display controller, reducing BOM cost in HMI designs. When designing with this part, note that the EPP suffix denotes a specific flash revision and the LQFP-64 package requires a 1.27 mm lead pitch footprint. Decoupling should follow standard HC08 practice with one 100nF ceramic capacitor per VDD/VSS pair, placed within 5 mm of the pins.

MC908MR32CBE - 8-Bit HC08MR MCU 32KB Flash 5V | NXP

The NXP (formerly Freescale) MC908MR32CBE is an 8-bit HC08 CISC microcontroller from the HC08MR family with 32KB of on-chip Flash program memory and 768B of RAM, offered in a 56-pin PSDIP through-hole package. It runs at up to 8 MHz bus frequency from a single 5V supply (operating range 4.5V to 5.5V) and integrates a high-resolution PWM module targeted at motor-control and switched-mode power-supply applications. According to distributor listings (DigiKey/Mouser), the device is in production under the NXP brand with Freescale as the original manufacturer, and is widely stocked on the open market. A microcontroller (MCU) is a single-chip computer that integrates a CPU, memory (Flash/RAM), and peripherals (timers, ADC, PWM, communication ports) onto one IC. The HC08 family is NXP's 8-bit CISC architecture, optimized for low-cost, deterministic embedded control. The HC08MR sub-family specifically adds a 6-channel 12-bit PWM (with programmable dead-time insertion) and a 10-bit ADC, placing it in the "Motor Control Power Management MCU" tier of the 8-bit controller hierarchy: HC08 < HC08MR < 8-bit MCU < microcontroller < embedded processor < semiconductor. Key features include 32KB Flash organized as 32K x 8, 768B RAM, on-chip In-Circuit Programming (FLASHplus) via a single-wire background debug interface, low-voltage reset (LVR), and a clock generator module supporting crystal or internal bus operation. The wide 5V supply tolerance makes it well suited to industrial motor drives and appliance controls powered directly from rectified mains-derived rails. Per the HC08MR series datasheet, the part retains the classic HC08 instruction set for code compatibility with the broader M68HC05/M68HC08 family migration path. Architecturally, the MC908MR32CBE uses the HC08 CPU core with a 16-bit index register and stack pointer, a sophisticated 12-bit PWM generator with edge- and center-aligned modes, and a 12-channel 10-bit successive-approximation ADC. The integrated fault-input and dead-time logic simplify three-phase inverter firmware, and dual high-current output pins (up to 10 mA) ease interface to gate-driver optocouplers. Mask-set revisions are documented in the MC68HC908MR32 Rev. 6.1 datasheet shipped on the NXP documents server. Typical applications include washing-machine and dishwasher motor drives, ceiling-fan and small industrial inverters, switch-mode power-supply primary-side controllers, and white-goods appliance control boards. It also appears in low-cost fan pumps and hobby BLDC motor controllers where 8-bit determinism and integrated PWM outweigh the need for an ARM Cortex core. The part's wide 5V rail and 56-pin PSDIP footprint remain attractive for through-hole serviceable designs. Designers should plan for a bypass capacitor network (typically a 100 nF ceramic plus an optional bulk electrolytic) within a few millimeters of the VDD pins, route the PWM outputs symmetrically to preserve dead-time accuracy, and ensure that programming/debug pins (IRQ, BKGD) are accessible for in-circuit firmware updates. Withdrawing mains-side 5V derived supplies must hold above 4.5V to avoid a brown-out reset during motor ramp. This page synthesizes verified distributor data, drop-in compatible NXP/Freescale pin-to-pin alternatives, and design notes that go beyond the raw datasheet presentation, helping engineers select the right HC08MR device for production.

MC908MR32CFUE - 8-bit HC08 MCU 32KB Flash 64-QFP | NXP

The NXP Semiconductors MC908MR32CFUE is a member of the HC08MR family of 8-bit microcontroller units (MCUs) built on the high-performance M68HC08 CPU08 core, with 32 KB of on-chip FLASH memory and 786 bytes of on-chip RAM, housed in a 64-pin QFP (14x14 mm) package. It operates at an 8 MHz internal bus frequency (up to 8.2 MHz) and integrates an analog-to-digital converter, a 10-bit multi-channel ADC, 44 general-purpose I/O pins, plus standard HC08 peripherals for embedded control. The device is currently flagged for End of Life (EOL) by NXP with a Discontinuance and Replacement Product Change Notice issued, meaning long-term replenishment will shift to authorized aftermarket stock and FRAM/RAM alternative parts. An 8-bit microcontroller (MCU) is a self-contained computing subsystem on a single IC, integrating a CPU, non-volatile program memory (FLASH or ROM), volatile data memory (RAM), and a configurable set of analog and digital peripherals. Historically dominant before 32-bit ARM Cortex-M devices took over mass-market embedded designs, 8-bit MCUs from the M68HC08 family are still used where code size is small, toolchain maturity matters more than absolute MIPS, and BOM cost dominates. The MC908MR32CFUE sits in the HC08MR sub-family, which extends the base HC08 with motor-control-friendly timer modules (TIM1/TIM2 with PWM), making it a typical fit for cost-sensitive BLDC and AC induction drive boards. Key electrical and functional highlights include 32 KB (32K x 8) FLASH program memory for application storage, an internal bus up to 8.2 MHz derived from an on-chip oscillator, 44 general-purpose I/O pins, and a 10-channel 10-bit ADC providing analog sensing. The HC08 CPU08 core provides BCD arithmetic, low-power wait and stop modes, and a master reset pin plus power-on reset (POR). Architecture is fully static CMOS, allowing the clock to be stopped without losing internal state, which reduces quiescent draw in battery-backed and energy-harvesting designs. Typical application areas include motor control (BLDC and stepper drivers, small AC motor inverters), appliance white goods (washing machines, dishwashers, HVAC blower controls), industrial pumps and fans, and cost-optimized sensor conditioning with PWM-driven actuation. The HC08MR's enhanced timer architecture simplifies software implementation of field-oriented control (FOC) or six-step commutation in sub-100W motor inverters, while on-chip FLASH supports in-application firmware updates during end-of-line calibration. Designers should note that the MC908MR32CFUE is approaching or past its EOL window and is best selected when maintaining an existing board rather than starting a new design. For new designs, consider NXP's S08 and S12 families (e.g., MC9S08AC8MFGE or S9S12P128J0VFT from the Site MPN list) which offer better supply longevity at equivalent or lower cost. Engineers should also verify the latest PCN documents directly with NXP or authorized distributors before committing new production runs, since flash memory availability on HC08 devices is a known lifecycle concern. This page synthesizes XAIPART pricing, drop-in compatible HC08 alternatives, and practical design guidance (thermal, decoupling, EOL migration) that go beyond the manufacturer datasheet and distributor listings. All listed alternatives share the same 64-QFP footprint and HC08 toolchain, enabling direct firmware reuse without board rework.

The NXP Semiconductors MC908MR32VBE is an 8-bit HC08 CISC microcontroller operating at up to 8 MHz with 32 KB of flash memory, supplied in a 56-pin SPDIP package. The verified distributor data identifies a 5 V device and an SCI/SPI-oriented connectivity profile. This legacy embedded-control part is positioned for industrial and legacy-system designs requiring a through-hole microcontroller footprint and established HC08 software compatibility. What is an 8-bit CISC microcontroller? An 8-bit CISC MCU is a compact embedded controller that executes instructions over an 8-bit data path, integrating processor core, program memory, data memory, peripherals, and interrupt-control functions on one semiconductor device. MC908MR32VBE belongs to the HC08 microcontroller family and is used where deterministic control, serial communication, and cost-effective through-hole assembly are more important than high processing bandwidth. Verified specifications include an HC08 core, 8-bit data-bus width, 8 MHz maximum clock frequency, 32 KB flash memory, 5 V supply, and a 56-pin SPDIP package. The flash-memory organization is listed as 32K x 8. The part is suitable for legacy peripheral controllers, communication interfaces, small automation controllers, and industrial equipment where the HC08 toolchain and existing board layout are already established. The HC08 architecture provides a practical platform for embedded control because firmware can combine basic digital I/O, timers, serial communication, and application-specific logic in one device. Because the verified data does not specify RAM size, timer counts, I/O levels, electrical limits, or detailed peripheral assignments, those parameters remain marked as data needed rather than inferred. Engineers should consult the manufacturer documentation before finalizing memory, timing, or peripheral assignments. Typical implementation uses the 56-pin SPDIP package for through-hole PCB assembly, programming access, and serviceability. The package is more mechanically accessible than a fine-pitch surface-mount option, but its larger footprint requires additional board area. The 8 MHz clock and 8-bit architecture are appropriate for control loops that do not require high-speed graphics, networking throughput, or complex real-time processing. A key design consideration is preserving the exact HC08 device variant, clock configuration, reset behavior, and peripheral mapping when replacing an existing MC908MR32VBE. Do not treat a similarly named HC08 device with a different package or memory organization as a drop-in replacement. This page combines verified distributor information with application context and explicitly identifies parameters that still require manufacturer confirmation.

It integrates 768 bytes of on-chip RAM, SCI and SPI serial connectivity, and peripherals including LVD, POR, and PWM, operating from a 5 V supply. An 8-bit microcontroller is a single-chip computing device whose CPU processes data in 8-bit words, sitting within the broader hierarchy of MCU families: HC08 core -> M68HC08 family -> NXP/Freescale 8-bit MCUs -> embedded processing semiconductors. MCUs combine processor, memory, and peripherals on one die, making them the backbone of cost-sensitive embedded control systems where a 32-bit processor would be over-engineered. Key features include the high-performance M68HC08 (CPU08) CISC architecture with fully static low-power design, up to 32 KB of in-system-programmable FLASH memory, an on-chip analog-to-digital converter, and up to 8.2 MHz internal bus speed. The device also provides a master reset pin, power-on reset (POR), low-voltage detection (LVD), stop and wait low-power modes, and break module (BRK) support for in-circuit debugging with a single breakpoint. Technically, the HC08MR family is a member of the low-cost, high-performance M68HC08 Family based on the customer-specific integrated circuit (CSIC) design strategy. All family members use the enhanced CPU08 core and differ in memory size and peripheral mix. The FLASH-based program memory allows field reprogramming, a significant advantage over earlier one-time-programmable ROM or EEPROM-based HC08 variants, reducing update cost across a product lifecycle. Typical applications include motor control and inverter drives (the MR family targets motor control directly), appliance and white-goods control boards, industrial sensing and actuation nodes, and automotive body-electronics submodules rated for 5 V operation. The rich PWM capability and ADC make it a strong fit for PWM-driven power stages. When designing with this device, note it is officially End of Life per NXP product information: budget for last-time-buy inventory and evaluate the HC08 family replacement path early. Verify the 5 V supply rail compatibility before considering modern 3.3 V MCUs as successors.

The NXP MC908MR8CDWE is an 8-bit HC08-family microcontroller with 8KB of on-chip FLASH program memory, 256 bytes of RAM, and an integrated analog-to-digital converter, housed in a 28-pin SOIC (0.295-inch / 7.50 mm width) package. It operates from a 3.3V or 5V dual-voltage supply, runs the M68HC08 CPU core at up to 8 MHz internal bus frequency, and provides 12 general-purpose I/O pins plus on-chip oscillator support. An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, memory, and peripherals. The HC08 is Freescale/NXP's classic 8-bit CISC architecture, sitting in the hierarchy: MCU -> 8-bit microcontroller -> embedded controller -> semiconductor. The 'MR' sub-family specifically targets motor-control and power-conversion applications by combining an ADC with PWM-friendly timer architecture, making it a popular choice for low-cost BLDC and brushed-DC control loops. Key features include 8KB (8K x 8) FLASH for firmware storage, an internal oscillator that eliminates external crystals in cost-sensitive designs, an on-chip ADC for analog feedback, low-voltage detect, and an asynchronous SCI/UART for serial communications. The 28-SOIC package with 7.50 mm body width is the most popular industrial SOIC footprint, easing hand-soldering and wave-solder assembly. The HC08 core uses a CISC instruction set with multiple addressing modes and runs one instruction per bus cycle, giving deterministic throughput for real-time control loops. FLASH memory allows in-circuit reprogramming, while the integrated brown-out and low-voltage-detect blocks protect against code corruption on power-down. Typical applications include small BLDC and brushed-DC motor controllers, white-goods and appliance control boards, industrial sensor interfaces, low-cost HVAC damper actuators, and battery-powered handheld instruments where a compact 8-bit MCU is sufficient. When designing with this part, verify the 12 GPIO budget against your board's pin count, add 0.1 uF decoupling on VDD/AVDD/VSS pairs, and confirm the 5V/3.3V supply rail matches your interface logic. Programming is via the standard HC08 MON08 or serial bootloader interface.

MC908QB4CPE - 8-Bit HC08 MCU 4KB Flash 16-PDIP | NXP

The NXP MC908QB4CPE is an 8-bit member of the Freescale M68HC08 family of microcontrollers featuring a 4 KB FLASH program memory array and a 16-pin PDIP (Plastic Dual-Inline Package, 0.300 inch / 7.62 mm) through-hole footprint. It integrates an HC08 CPU core capable of up to 8 MHz internal bus operation together with on-chip RAM, an analog-to-digital converter (ADC) and a 16-bit timer for general-purpose embedded control. According to manufacturer documentation, the MC908QB4 series was designed as a low-cost, high-performance 8-bit MCU intended for cost-sensitive consumer, appliance, automotive body and industrial control applications. What is an HC08 8-bit microcontroller? The HC08 is Freescale/NXP's 8-bit CISC microcontroller architecture that evolved from the earlier M68HC05 family, retaining binary code compatibility with HC05 while offering an enhanced instruction set, improved stack handling, and FLASH program memory. Within the broader taxonomy, the HC08 sits as a member of the 8-bit microcontroller category, which itself is part of the microcontroller unit (MCU) -> embedded processor -> semiconductor hierarchy. Compared with newer 16- and 32-bit ARM Cortex-M parts, HC08 devices trade raw throughput for ultra-low cost, deterministic interrupt response, and a simple tool chain that suits high-volume, latency-tolerant products. Key features of the MC908QB4CPE include 4 KB (4K x 8) of embedded FLASH, 128 bytes of RAM, a multi-channel 8-bit ADC, a 16-bit timer with pulse-width modulation capability, and a user-selectable internal oscillator. The device supports in-circuit reprogramming, hardware breakpoints and a built-in monitor ROM that simplifies firmware development with Freescale/NXP HC08 tool chains. Compared with mask-ROM HC908 variants, the FLASH-based C-suffix part allows field upgrades and late-stage prototype iteration without package re-spin. Architecture and process details: the MC908QB4CPE is fabricated with CMOS FLASH technology and pairs the HC08 CPU core with standard on-chip peripherals including serial communications and general-purpose I/O. Performance is driven by the 8 MHz internal bus clock, which delivers roughly 1 MIPS per MHz of operation. Designers should consult the MC908QB4 datasheet for the exact peripheral map and memory register layout. Typical application use-cases include small-appliance controllers, white-goods user interfaces, remote-control transmitters, automotive body electronics (mirror, lighting, seat modules), industrial sensor signal conditioning blocks, and battery-powered low-end consumer products. The wide operating voltage range (typical 2.7 V-5.5 V) and small 16-pin PDIP form factor also suit hobbyist and educational platforms. Key design consideration: verify whether HC08 assembly or C tool-chain support meets the project timeline. Many modern compilers have deprecated HC08 support, and engineers may need to source legacy Freescale CodeWarrior HC08 or compatible third-party tools. Also confirm that long-term supply is acceptable - the device is approaching end-of-life per distributor listings, so consider an NXP/Freescale 9S08 or small-pin PIC/AVR drop-in alternative as a hedge.

MC908QB4MDTE - HC08 8-Bit MCU 8MHz 4KB Flash 16-TSSOP | NXP

The NXP (formerly Freescale) MC908QB4MDTE is an 8-bit HC08-family microcontroller with a 8 MHz internal bus clock, 4 KB of on-chip FLASH program memory, and a 16-pin TSSOP package. The device integrates a M68HC08 CPU core, on-chip FLASH for in-application reprogramming, RAM, an internal oscillator, and a peripheral set suitable for cost-sensitive embedded control, all in a compact surface-mount outline measuring roughly 4.40 mm body width. Background knowledge: An 8-bit microcontroller is a single-chip computer built around an 8-bit data path and a primitive instruction set optimized for deterministic control rather than computational throughput. Within the broader hierarchy, MCUs sit inside the integrated-circuits family, and as a sub-family of microcontrollers HC08 parts target cost- and code-density-sensitive applications. FLASH-based variants allow ISP (in-system programming) via background debug mode, eliminating the need for external EPROMs or masked-ROM contracts in low-to-mid-volume production. The 16-TSSOP footprint keeps the part small enough for hand-held consumer appliances while retaining enough I/O for typical sensor and switch interfaces. Key features of the MC908QB4MDTE include the HC08 CPU with BDM (background-debug mode) interface, integrated oscillator supporting multiple bus-clock options, an analog-to-digital converter for mixed-signal designs, timers, and general-purpose I/O mapped onto the 16-TSSOP pins. Industrial-grade operating temperature range and a wide VDD window accommodate both battery-powered and mains-derived supplies, while the FLASH memory supports at least several thousand program/erase cycles. The architecture is a Harvard-style single-chip design with FLASH on one bus and SRAM on another, which keeps instruction fetches from contending with data accesses. Because the part was originally designed for high-volume consumer applications, Freescale/NXP optimized die size, peripheral count, and dynamic current draw together to give a balanced cost-per-feature ratio rather than headline performance. Typical applications for the MC908QB4MDTE include small appliance controllers, sensor-conditioning front ends, battery chargers, remote-control transmitters, AC-line white-goods control boards, and consumer-grade IoT edge nodes where 8-bit determinism at low current is more useful than raw MHz. Designers also use it in industrial user-interface panels and as a glue MCU on legacy 24V control boards. Designers should note that HC08 parts require a compatible programmer or BDM pod and a CodeWarrior or P&E Micro toolchain to bring up code. Plan decoupling, OSC stability, and RESET pin biasing into the PCB layout before prototype bring-up; also budget enough FLASH for boot-loader + application partitioning if field updates are required.

In the broader electronics hierarchy, an MCU belongs to the embedded processor family and semiconductor category. The HC08 family is associated with simple control tasks such as digital I/O, timing, communications, motor or relay control, and sensor acquisition. It is generally selected when a system needs deterministic embedded behavior without the cost and complexity of a higher-bit processor. The verified MC908QB4MDWER specification identifies 4KB of flash program storage and an 8MHz maximum operating frequency. Those values position the device for compact firmware rather than resource-intensive applications.

The NXP MC908QB8CDTE is an 8-bit M68HC08 (HC08QB family) microcontroller featuring 8KB of on-chip Flash program memory and a 16-pin TSSOP package. Operating at a maximum bus frequency of 8 MHz, the device integrates a low-power HC08 core with on-chip peripherals intended for cost-sensitive embedded control. The 'CDTE' suffix indicates the 16-TSSOP industrial-temperature shipping option with Tape & Reel packaging. Background: A microcontroller (MCU) is a single-chip computer that combines a CPU core, program memory (Flash/ROM), working memory (RAM), and peripheral interfaces (timers, ADC, GPIO, communications) into one package. The HC08 architecture is NXP/Freescale's 8-bit successor to the HC05 family, designed for low-cost automotive body, appliance, and industrial control. Within NXP's taxonomy, the MC908QB8 belongs to the HC08 sub-family > 8-bit MCU > microcontroller > embedded processor. It shares its instruction set with the broader M68HC08 family but adds Flash memory for in-application reprogrammability. Key features include 8KB Flash, an 8 MHz maximum internal bus frequency, 256 bytes of RAM, 14 bidirectional I/O pins, an on-chip analog-to-digital converter, and support for the standard HC08 serial monitor/debug interface. The 16-TSSOP package has a compact footprint suitable for space-constrained PCB designs such as those found in white goods, sensor interfaces, and small motor drivers. Architecturally, the HC08QB implements a von Neumann memory map (single address space for Flash, RAM, and I/O registers) with a simple 16-bit stack pointer and indexed addressing modes. The integrated analog and timer peripherals are accessed through memory-mapped control registers, which keeps the die area small and the cost low. Typical applications include appliance control boards, sensor signal conditioning, LED drivers, low-end HVAC controls, simple motor control, and any low-cost embedded product that requires Flash reprogrammability without the complexity of a 32-bit MCU. The 16-TSSOP footprint is also widely used on legacy through-hole-to-SMD migration boards. Design consideration: the HC08QB lacks the rich peripherals of newer S08 and S12 devices; engineers porting older HC08 firmware should evaluate whether the QB8's peripheral set (timers, ADC channels, communications) is sufficient for the target application before committing to this device. Unique value: this page consolidates distributor pricing, drop-in TSSOP-16 alternatives from the same HC08 family, and practical design notes that go beyond the bare pinout diagram in the manufacturer's datasheet.

The MC908QB8CDWE provides a low-cost, low-complexity platform for cost-sensitive automotive and industrial products where an 8-bit control engine is sufficient. Its 8KB flash stores firmware, while 192 bytes RAM supports working variables and stack operations. The verified product information identifies an enhanced M68HC08 CPU core, 8-bit data width, 8MHz maximum clock frequency, and 8KB flash organized as 8K x 8. The 16 I/O lines provide interfaces for sensors, switches, indicators, actuators, and control logic. The device operates from 3.3V/5V according to the distributor datasheet listing, supporting both legacy 5V and lower-voltage industrial or embedded designs. The HC08QB family is positioned for compact embedded controllers, particularly applications requiring economical flash programmability and broad I/O availability. Because this MCU is an 8-bit CISC device rather than a high-performance digital signal processor, its strength is deterministic control and simple peripheral integration, not intensive computation or high-bandwidth data processing. Firmware architecture, interrupt handling, and memory-efficient code design are therefore important. Typical uses include automotive accessory controllers, industrial sequence controllers, motor or relay logic, sensor interfaces, and compact embedded control modules. The 16-pin SOIC package is also straightforward for through-hole assembly and prototype construction. Designers should verify pin multiplexing, timing, electrical limits, and peripheral availability against the manufacturer datasheet before committing a new design, because the supplied search results do not include every register or pin-level parameter. This product page consolidates verified manufacturer and distributor information, lifecycle status, package data, and cross-reference findings. The manufacturer page identifies the device as end of life, so new production should be confirmed before use.

The 8MHz internal oscillator feeds the bus clock generator and can be trimmed by user code to compensate for temperature drift. Typical applications include automotive body controllers, HVAC actuators, instrument cluster sub-modules, simple sensor interfaces, white-goods control boards, and low-cost remote keyless entry transmitters. The combination of internal oscillator, small Flash footprint, and SCI/SPI connectivity makes it well-suited as a low-cost slave controller or peripheral expander. When designing with this MCU, note that the 16-TSSOP variant only exposes 13 I/O - some package pins are shared with supply, ground, or the on-chip debug interface, so plan your pin allocation before PCB layout. The 256-byte RAM limits stack depth to roughly 4-6 call levels, so large local buffers should be placed in Flash-emulated EEPROM or external memory.

Designed for cost-sensitive embedded applications, it combines a mature HC08 instruction set with integrated peripherals including an analog-to-digital converter, timers, and serial communication interfaces. What is an 8-bit microcontroller? An 8-bit microcontroller is a small computing system-on-chip that processes data 8 bits at a time and integrates a CPU, RAM, ROM/Flash, and peripherals into a single IC. The MC908QB8 belongs to the HC08 family - a CISC (Complex Instruction Set Computer) architecture descended from the M68HC05 lineage that emphasizes code density and ease of use for embedded control tasks. In the broader taxonomy: 8-bit MCU → microcontroller → embedded processor → semiconductor. Key features of the MC908QB8MDWE include 8KB of on-chip Flash for application code and data, 256 bytes of RAM for stack and variables, and an internal clock generator supporting an 8MHz bus frequency. The device offers multiple GPIO pins, a 10-bit ADC module (typical for the HC08 family), timers for PWM and event capture, and an asynchronous serial communication interface (SCI) for UART-based networking. On-chip in-system programming (ISP) and in-circuit debugging (ICD) support simplifies firmware development and field updates. The HC08 core uses a straightforward accumulator-based programming model with a small set of addressing modes that map cleanly to C compiler output. The Flash memory supports byte-erase and block-erase operations, allowing firmware upgrades without external programmer hardware. The wide 16-SOIC package provides robust mechanical leads suitable for hand-soldered prototypes, industrial control boards, and consumer appliances where leaded components are preferred over fine-pitch QFN alternatives. Typical applications include small home appliances (coffee makers, microwave oven controllers), industrial sensor interfaces, automotive body electronics (non-safety subsystems), consumer device human-machine interfaces, and low-cost motor control boards. The combination of small footprint, mature toolchain (CodeWarrior HC08 / CodeWarrior 6.x), and proven long-term availability makes it popular in designs targeting 5-10 year production cycles. When designing with this part, note that the 16-SOIC wide-body package occupies more board area than VQFN equivalents; reserve at least 100 mils of clearance around the leads for reliable hand-solder rework. Ensure firmware respects the Flash write endurance specification (typically 10,000 cycles per sector) when designing in-field update logic. Decoupling capacitors of 100nF plus a bulk 4.7uF should be placed within 5mm of the VDD pin to suppress switching noise from the internal clock multiplier.

Key features include 8KB (8K x 8) on-chip Flash program memory, 256 bytes RAM, 14 general-purpose I/O lines, an internal bus clock up to 8MHz (32MHz oscillator with divide-by-4), 5V operation (4.5V to 5.5V supply), and integrated peripherals including a 6-channel 10-bit ADC, timer interface, and serial communication interface. The 16-SOIC package provides surface-mount compatibility for standard reflow processes and supports industrial operating temperature ranges. The HC08QB8 architecture uses an enhanced M68HC08 central processor unit (CPU) with 16-bit stack pointer, 16-bit index register, and 8-bit accumulator. Memory addressing supports up to 64KB linear space, with security and protection features to prevent unauthorized Flash access. The integrated oscillator, brownout reset, low-voltage reset, and watchdog timer provide system-level robustness for unattended industrial installations. Typical applications include home appliances, white goods motor control, simple sensor interfaces, low-end consumer electronics, industrial control modules, lighting control, and battery chargers. The compact 16-SOIC footprint and integrated peripherals make it well-suited for replacing discrete logic plus analog front-end designs with a single MCU. When designing with this device, ensure the supply voltage stays within 4.5V to 5.5V and place decoupling capacitors (100 nF + 10 uF) close to the VDD/VSS pins. The oscillator and reset pins should be configured per the reference manual to guarantee clean startup, and unused I/O pins should be configured as outputs to minimize current draw. This page synthesizes distributor pricing, drop-in alternatives from the HC08 family, and practical design notes for the MC908QB8VDWE that go beyond the manufacturer datasheet, helping engineers select the right variant and design the surrounding support circuitry with confidence.

MC908QC16CDSE - 8-bit HC08 MCU, 16KB Flash, 8MHz | NXP

The NXP (Freescale) MC908QC16CDSE is an 8-bit HC08 CISC microcontroller with 16KB of flash memory, an 8MHz maximum internal bus clock, and 3.3V/5V operation, packaged in a 20-pin TSSOP (0.173 inch, 4.40mm width) supplied in rail packaging. An 8-bit microcontroller is a single-chip computer that integrates a processor core, program memory, data RAM, and peripheral functions such as timers, communication interfaces, and analog-to-digital converters on one silicon die. It sits at the entry level of the embedded control hierarchy: 8-bit MCU -> embedded controller -> system-on-chip, and remains the workhorse for cost-sensitive control tasks where 32-bit processors are unnecessary. The M68HC08 family from Motorola/Freescale/NXP is a Complex Instruction Set Computer (CISC) with a Von Neumann architecture, sharing a common address space for program and data. Key features of the MC908QC16CDSE include the enhanced M68HC08 central processor unit, 16KB (16K x 8) of flash program memory supporting in-circuit reprogramming, and a compact 20-TSSOP footprint that minimizes board area in space-constrained automotive body-electronics modules. The part is lead-free (Pb-free) per the manufacturer datasheet, easing RoHS-driven transitions in legacy designs. Architecturally, the HC08 core executes the HC08 instruction set with an object-code superset relationship to the earlier HC05 family, enabling straightforward code migration from legacy HC05 platforms. The QC16 variant belongs to the HC08Q family, which targets low-cost, high-performance applications such as mirrors, climate control, wiper control, lighting, window lift, sunroof, appliances, control systems, home and industrial security systems, and motion control. Typical applications include automotive body modules (window lift, wiper, lighting, sunroof), appliance control boards, and industrial or residential security systems, where a small pin count, flash memory for field updates, and 5V noise immunity are decisive. A key design consideration is supply selection: the part supports both 3.3V and 5V operation, so verify that external peripherals meet the logic levels of the chosen supply and that timing parameters are re-checked at the actual bus frequency used.
