MC908GR8ACDWE - HC08 8-bit MCU, 7.5KB Flash, 28-SOIC | NXP

The NXP Semiconductors MC908GR8ACDWE is an 8-bit HC08 microcontroller with 7.5KB (7.5K x 8) of FLASH program memory, an 8MHz internal bus clock capability, and operation from 3.3V or 5V supplies, housed in a 28-pin wide SOIC (0.295 inch / 7.50mm width) package. An 8-bit microcontroller unit (MCU) is a single-chip computer integrating a CPU core, program memory, RAM, I/O ports, and peripherals such as timers and serial interfaces. Within the power-management hierarchy of embedded systems, the MCU acts as the central controller, sitting above discrete logic and below application processors. The HC08 family, originally developed by Motorola and Freescale, now manufactured by NXP, is a CISC-architecture 8-bit controller family widely used in cost-sensitive embedded control. Key features of the MC908GR8ACDWE include the enhanced HC08 core executing HC08 CISC instructions at up to 8MHz, on-chip FLASH memory supporting in-circuit reprogramming, and a dual-supply operating range of 3.3V to 5V that bridges legacy 5V industrial designs and lower-power 3.3V systems. The wide-body 28-SOIC (DWE suffix) package provides generous 2.54mm-class lead pitch for hand soldering and prototyping, making it popular for service and maintenance designs. Architecturally, the HC08 core uses an accumulator-plus-index-register programming model with a large set of addressing modes, and the GR8 variant integrates FLASH, RAM, timers, and multi-purpose I/O on a single die, reducing bill-of-materials count versus two-chip solutions. The ADC and timer resources of the GR series support motor control, sensing, and timing-critical loops. Typical applications include industrial control boards, appliance and HVAC controllers, battery chargers, automotive body modules in legacy platforms, and instrumentation front ends where a 5V-tolerant 8-bit MCU simplifies design. When designing with this device, verify supply-voltage selection (3.3V versus 5V) against peripheral voltage limits and confirm oscillator configuration for the 8MHz bus target.

MC908GR8CDWE - 8-bit HC08 MCU, 7.5KB Flash, 28-SOIC | NXP

The NXP MC908GR8CDWE is an 8-bit HC08 CISC microcontroller integrating 7.5 KB of on-chip Flash program memory, 384 bytes of RAM, and 17 general-purpose I/O pins in a 28-pin wide-body SOIC package. It executes instructions from the M68HC08 core at an internal bus speed of 8 MHz and operates from a single 3.3 V or 5 V supply. The device also embeds an internal oscillator, eliminating the need for an external crystal in cost-sensitive designs. Background: An 8-bit microcontroller (MCU) is a single-chip computer built around an 8-bit data bus and a CISC (Complex Instruction Set Computer) or RISC instruction set, integrating CPU, non-volatile program memory (Flash/ROM), volatile data memory (RAM), and a set of peripherals such as timers, ADC, and communication controllers. Within the broader hierarchy, an MCU belongs to microcontrollers -> microcomputers -> embedded processors -> semiconductors. The Freescale/NXP HC08 family is a CISC architecture widely used in automotive body electronics, white goods, and industrial control where deterministic interrupt response and low cost matter more than raw throughput. Key features include an 8 MHz internal bus, an on-chip oscillator, 7.5 KB of Flash, 384 bytes of RAM, and 17 GPIO pins. The wide operating voltage range (typically 3 V to 5.5 V) and a multi-channel timer make the part attractive for battery-backed and brown-out-sensitive applications. The 28-SOIC wide-body package simplifies hand-soldering and rework on through-hole-friendly 1.27 mm pitch footprints. The HC08 core uses a Von Neumann architecture with a 16-bit stack pointer, allowing efficient C compilation and an upward migration path to the enhanced HCS08 family. The integrated Flash supports in-application programming via a background debug mode, simplifying field firmware updates. Typical applications include appliance control boards, simple sensor signal conditioning nodes, automotive body controllers, HVAC actuators, and remote keyless entry transmitters. The wide 28-SOIC footprint and mature toolchain also make it suitable for legacy industrial PLC I/O modules where the part was originally designed in. When designing with this part, ensure the supply decoupling network includes a 100 nF ceramic capacitor close to VDD/VSS plus a bulk capacitor of at least 4.7 uF, since the internal oscillator is sensitive to VDD ripple. Always verify oscillator trimming against the production temperature range, and budget for the 1.9 V minimum Flash programming voltage if in-circuit programming is used. This page synthesizes distributor pricing, parametric alternatives, lifecycle status, and practical design notes that go beyond the manufacturer datasheet.

MC908GR8CPE

MC908GR8CPE - 8-Bit HC08 MCU, 7.5KB Flash, 28-PDIP | NXP

The NXP (formerly Freescale / Motorola) MC908GR8CPE is an 8-bit HC08 CISC microcontroller integrating 7.5 KB of on-chip Flash program memory and 384 bytes of RAM, housed in a 28-pin PDIP (0.600 inch, 15.24 mm) through-hole package. It runs at up to 8 MHz internal bus speed from a 3.3 V or 5 V supply, with 17 general-purpose I/O lines, an internal oscillator, and a dedicated ADC plus serial and timer peripherals. The 'GR' family is engineered for low-cost embedded control in legacy industrial, automotive body, and consumer designs that remain on long production cycles. An 8-bit microcontroller is a single-chip computer that combines a CPU, volatile RAM, non-volatile program memory, and assorted peripherals (timers, ADC, serial ports, GPIO) in one package. Within the broader semiconductor taxonomy it belongs to the microcontroller sub-family of microcontrollers and microprocessors, which themselves sit inside the Integrated Circuits > Microcontrollers category. The HC08 family is Motorola's original CISC 8-bit architecture using an accumulator plus index-register model and a unified 16-bit address space, predating but architecturally related to the later HC(S)08 cores that extended the line into low-power and in-circuit reprogrammable designs. Key features of the MC908GR8CPE include its 7.5 KB Flash (which is in-circuit programmable on EPP-equipped variants), the integrated 10-channel 8-bit ADC, dual SCI and SPI serial interfaces, a 16-bit timer with two capture/compare channels, and built-in safety features such as COP watchdog and LVI (low-voltage inhibit) reset. The internal oscillator eliminates an external crystal for many designs, reducing BOM cost. The 28-PDIP package also exposes external interrupt lines and keyboard-interrupt wake-up pins, simplifying user-interface designs. Application fit is anchored in cost-sensitive, brownfield embedded control where an established 8-bit core, ample Flash for state machines, and simple through-hole PCB assembly are valued. The wide 3 V to 5 V operating range, plus the analog and timer peripheral mix, make it well suited to appliance controls, sensor conditioning nodes, simple HMI panels, automotive interior accessories on body-bus systems, and industrial control sub-systems where deterministic, low-bandwidth logic is more important than computational throughput.

It belongs to the M68HC08 family and uses the enhanced CPU08 core for cost-sensitive embedded control applications targeting consumer and industrial equipment. A microcontroller is a compact embedded-computing device that integrates a CPU, program memory, data memory, I/O, timers, and communication peripherals on one semiconductor package. The HC08 MCU family provides a straightforward 8-bit architecture for products that do not require the processing power or memory capacity of a 32-bit embedded controller. MC908GT16CBE is positioned for general-purpose control, monitoring, and simple user-interface functions. Verified listings identify 16 KB of Flash program memory, 512 x 8 RAM, 36 I/O pins, an 8 MHz operating speed, and a 42-pin SPDIP package. The device is supplied in tube packaging according to the retrieved part data. Its through-hole package is useful for prototypes, industrial controllers, educational platforms, and systems assembled where leaded-package compatibility is preferred over a compact surface-mount footprint. The HC08 platform is described in the retrieved data as a low-cost, high-performance member of the M68HC08 family. Its 8-bit CPU08 architecture is suitable for sequential control logic, keypad and display interfaces, sensor acquisition, actuator control, and low-to-moderate-rate communication tasks.

Typical design uses include small industrial equipment, consumer products, educational controllers, and legacy embedded systems requiring an 8-bit HC08 architecture. Because the exact pin functions and peripheral map are not supplied here, PCB and firmware work should use the official MC908GT16CBE datasheet or an authorized technical document rather than relying only on distributor summaries. The main engineering trade-off is the 16 KB Flash limit combined with an 8 MHz 8-bit core. This is appropriate for compact control logic, but firmware growth, protocol stacks, and modern connectivity may exceed its memory budget. Confirm toolchain availability, interrupt requirements, timing, and board-level pin compatibility before committing to a new design. This product summary consolidates the verified distributor specifications, sourcing information, package constraints, and selection considerations. It also distinguishes confirmed facts from missing electrical details so engineers can make an informed sourcing and design decision.

MC908GT8CBE

MC908GT8CBE - 8MHz 8KB Flash 8-Bit MCU | NXP | 42-PDIP

The NXP Semiconductors MC908GT8CBE is an 8-bit HC08 microcontroller operating at 8 MHz with 8 KB (8K x 8) of FLASH program memory in a 42-pin PSDIP package. It is associated with the Freescale Semiconductor MC908GT8 family and is identified by distributor listings as an HC08 microcontroller with 34 I/O and an operating-temperature range of -40°C to +85°C. An 8-bit microcontroller is a compact embedded controller used to execute firmware, read sensors, control actuators, and manage communication or timing functions. In the hierarchy of electronic components, the MC908GT8CBE belongs to the MCU -> microcontroller -> embedded processor -> semiconductor category. Its HC08 architecture and modest 8 MHz clock position it for cost-sensitive embedded control rather than high-throughput processing. The verified listing specifies FLASH memory of 8 KB, an 8-bit core, and 8 MHz operation. Other listings identify an 8x8-bit ADC, 34 I/O, and a 42-pin through-hole package. The available source material does not provide a complete, consistent set of electrical limits such as RAM, supply voltage range, ADC timing, peripheral configuration, or absolute maximum ratings, so those parameters remain marked as data needed rather than inferred. Typical engineering uses for this device family include basic embedded control, keypad and display interfaces, simple motor or relay sequencing, industrial modules, and low-cost controller boards. The 42-pin package provides a practical through-hole footprint for prototyping and legacy industrial equipment, although it is physically larger than modern surface-mount MCU packages. Because the MC908GT8CBE is reported as obsolete or EOL in one verified source, replacement planning should begin by checking availability and pin-level compatibility rather than assuming that a functionally similar MCU is drop-in compatible. The listed alternatives include family members and comparison candidates, but the supplied data does not verify five pin-compatible drop-in substitutes, so they are not promoted as guaranteed replacements.

MC908GZ16CFAE - 8MHz 8-bit HC08 MCU 16KB Flash | NXP | LQFP-48
MC908GZ16CFAE

MC908GZ16CFAE - 8MHz 8-bit HC08 MCU 16KB Flash | NXP | LQFP-48

The NXP MC908GZ16CFAE is an 8-bit HC08-family microcontroller built on the M68HC08 central processor unit (CPU08), operating at 8 MHz with 16 KB of on-chip Flash program memory and housed in a 48-pin LQFP (7x7 mm) surface-mount package. It targets cost-sensitive embedded applications that need reliable Flash programmability, a small footprint, and the established HC08 toolchain. Per the NXP product page, this part has reached End-of-Life and is now served through authorized distributors with last-time-buy opportunities before full discontinuation. An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, non-volatile program memory, working RAM, and a configurable set of peripheral blocks (timers, ADC, communication ports, GPIO). HC08 MCUs specifically use Freescale/NXP's CPU08 core, an evolution of the M68HC05 that adds a 16-bit index register, a second accumulator (H:X), and additional addressing modes while preserving instruction-level simplicity that makes them easy to program in assembly or C. In the system hierarchy they sit below 16-bit and 32-bit MCUs, and are commonly chosen when deterministic timing, low unit cost, and proven long-term availability matter more than raw computational throughput. Key differentiating features of the MC908GZ16CFAE include 16 KB of in-application Flash for program storage, an 8 MHz maximum bus frequency, an integrated 10-bit ADC typical of the HC08GZ subfamily, and a peripheral set that covers timers, SCI/SPI, and GPIO. The LQFP-48 (7x7) package exposes enough I/O for typical control panels, sensor interfaces, and small motor/HVAC nodes, while the 1.8 V to 3.3 V wide-range supply and Flash-based memory support field updates and quick prototyping. Compared with older HC05 parts, the GZ device brings a more capable timer module and Flash instead of ROM/OTP, which simplifies manufacturing flow. Typical applications include white-goods and appliance control boards, HVAC damper and fan controllers, low-end industrial sensor nodes, automotive body electronics (non-safety), and legacy industrial automation where the HC08 code base is preserved. Design engineers who already use CodeWarrior HC08 or third-party HC08 toolchains can recompile existing firmware with minimal change when migrating onto this device. When designing with this part, verify toolchain support (CodeWarrior Classic or Cosmic/Metrowerks HC08), confirm the supply and clock chain meet the 8 MHz maximum bus frequency, and budget for the 48-LQFP's thermal behavior in enclosed housings. Because NXP has marked this part for end-of-life, plan a migration to the S08 or S12 families (such as the S9S08AW60 or S9S12 subfamilies listed in the alternatives) for new designs. This page consolidates distributor availability, drop-in same-family equivalents, and practical design notes not found in the original datasheet.

MC908GZ16MFAE

MC908GZ16MFAE - 8-Bit 8MHz 16KB MCU | NXP | 48-LQFP

The NXP Semiconductors MC908GZ16MFAE is an 8-bit HC08-family microcontroller with a CPU08 core, 8 MHz operating speed, 16 KB of program Flash memory, and a 48-LQFP package. It is designed for embedded control systems that require modest processing performance, integrated memory, and a conventional parallel GPIO-oriented architecture. The device is identified by the verified distributor listing as an HC08 microcontroller with 16 KB (16K x 8) Flash memory and 37 I/O pins. An HC08 microcontroller is a type of 8-bit microcontroller: a programmable semiconductor containing a CPU core, program memory, data memory, peripherals, and input/output interfaces for embedded control. In the hierarchy, an MCU is a microcontroller IC, while the HC08 family provides an 8-bit CPU08-based platform within the broader M68HC08 family. This class of controller is suited to appliance controls, industrial interfaces, sensor systems, and compact automation products where deterministic control and low-cost integration are more important than high compute throughput. The principal verified specifications are the 8 MHz speed, 16 KB Flash program memory, 1 KB RAM, 37 I/O pins, and 48-LQFP package. The Flash memory provides firmware storage, while the RAM supports working data and stack operations. The 37-pin I/O count provides external digital connectivity for sensing, actuation, communication modules, and control signals. Exact supply voltage, timer configuration, communication peripherals, electrical limits, and temperature limits were not present in the supplied verified data and are identified in the validation fields where applicable. The CPU08 architecture is an enhanced 8-bit processor platform rather than a high-performance application processor. Its role is therefore focused on embedded control: reading inputs, executing control logic, managing state, and driving outputs. The verified sources describe the device as part of the low-cost, high-performance HC08GZ family, whose members use the enhanced M68HC08 CPU08 core. This architecture should be considered when migrating firmware or selecting an alternative: software compatibility, memory-map details, peripheral availability, and electrical timing must be checked independently. Typical application areas include small appliance controllers, industrial control panels, sensor-interface boards, keypad and display systems, motor or relay control logic, and compact embedded products requiring a 48-pin surface-mount microcontroller. The 8 MHz clock is suitable for control-loop tasks that do not require high bandwidth. The available verified data does not specify a particular peripheral list, so designers should consult the manufacturer datasheet for timer, serial-interface, analog, and interrupt details before finalizing a design. A key engineering consideration is lifecycle planning. The NXP product page result identifies the MC908GZ16MFAE as End of Life, so new designs should confirm migration or approved sourcing requirements with NXP and authorized distributors. For an existing PCB, preserve the 48-LQFP footprint, pin assignment, supply requirements, oscillator configuration, and firmware memory expectations. Do not substitute an electrically similar MCU solely by nominal memory or clock speed; verify pin compatibility, peripheral mapping, reset behavior, and software support. This page consolidates the verified distributor specifications, official lifecycle indication, package data, and application-oriented design guidance for engineers evaluating this obsolete 8-bit MCU. It distinguishes documented facts from parameters that still require manufacturer-datasheet confirmation, helping buyers assess supply risk and decide whether a redesign or qualified migration is more practical.

MC908GZ32MFAE

MC908GZ32MFAE - 8-bit HC08 MCU, 32KB Flash, 48-LQFP | NXP

The NXP (formerly Freescale) MC908GZ32MFAE is an 8-bit HC08GZ family microcontroller featuring 32 KB of Flash program memory, 1.5 KB of RAM, and 37 general-purpose I/O pins, housed in a 48-pin LQFP (7x7 mm) package. The device integrates the enhanced M68HC08 central processor (CPU08) with a 8 MHz internal bus clock, on-chip EEPROM, and a 12-channel, 10-bit ADC, targeting cost-sensitive embedded applications in industrial control, white-goods, and automotive body electronics. Background. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program and data memory, peripherals, and I/O onto one die. An 8-bit MCU organizes data in 8-bit bytes and is optimal for deterministic bit-level I/O, simple state machines, and cost-constrained control loops. Within the NXP portfolio, the HC08 sits between legacy 68HC05 and the later S08/Coldfire families; it uses the CPU08 core that adds a background debug mode, multiply-accumulate instructions, and a wider indexed addressing mode while keeping classic M68HC08 instruction-set compatibility. Key features include 32 KB of Flash program memory with in-application reprogrammability, 1.5 KB of on-chip RAM and 256 bytes of EEPROM for non-volatile parameter storage, 37 bidirectional I/O lines, a 12-channel 10-bit successive-approximation ADC with 2.5 us conversion time, a serial peripheral interface (SPI), a serial communications interface (SCI), and an inter-IC (IIC) bus. Two 16-bit timer/PWM modules support motor and lighting control. Operating voltage is 3.0 V to 5.5 V with internal voltage regulation. Architecturally, the HC08GZ family combines Harvard-style separate program and data buses with a unified memory map that lets all memory regions host code. A 16-bit index register, 16-bit stack pointer, and a low-power STOP/WAIT mode are implemented in the CPU08 core. Security features include a Flash read-protection byte and an LVI/LVR low-voltage reset. The 10-bit ADC uses a switched-capacitor successive approximation topology with sample-and-hold, and its analog mux supports up to 12 channels shared with digital I/O. Typical applications include HVAC control boards, washing-machine and dishwasher user-interface controllers, automotive body modules such as seat and lighting controllers, keypad/LED scanning front panels, and small sensor-interface nodes. The wide 3.0 V-5.5 V supply range and automotive temperature grade (-40C to +125C on selected variants) suit both industrial and in-cabin automotive environments. A key design consideration is the part's End-of-Life status announced by NXP: production inventory is now sourced exclusively from authorized distributors and aftermarket stockists such as Rochester Electronics. Engineers designing new platforms should evaluate the NXP S08 family (e.g. S08GZ family) or comparable 32-bit Cortex-M0+ devices from S08JS16/S08QD4 as long-term alternatives. This page synthesizes verified distributor pricing, cross-brand drop-in alternatives, and application design notes that are not available on any single distributor page, giving engineers the information needed for both current repair/replenishment and forward migration planning.

MC908GZ32MFUE - 8MHz HC08 32KB Flash MCU 64-QFP | NXP

The NXP (formerly Freescale) MC908GZ32MFUE is an 8-bit HC08-family microcontroller integrating a CPU08 core running up to 8 MHz with 32 KB of on-chip Flash and a 64-pin QFP (14x14 mm) package. The HC08GZ family targets low-cost, high-performance embedded control with on-chip peripherals including ADC, timers, SCI/SPI and GPIO. The 'MFUE' suffix indicates the 64-QFP industrial-temperature grade supplied in tray packaging. An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, non-volatile program memory (Flash/ROM), volatile data memory (RAM), and peripheral interfaces on one die. Within the taxonomy, the MC908GZ32MFUE is a Flash-based MCU -> microcontroller unit -> embedded processor -> semiconductor IC. The M68HC08 instruction set, an enhanced successor to the M68HC05, offers indexed addressing, multiply instruction, and a flat memory model widely used in automotive body, appliance and industrial-control designs. Key features of the MC908GZ32MFUE include 32 KB (32K x 8) Flash program memory, 1.5 KB on-chip RAM, an 8-channel 10-bit ADC, multiple timer modules, and serial communication interfaces (SCI, SPI). It operates from 3.0 V to 5.5 V across the industrial -40 °C to +85 °C range, with low-power stop and wait modes that suit battery- and line-powered control modules. The 64-QFP package provides generous I/O count for mixed-signal control boards. Architecturally, the device uses the M68HC08 CPU08 core with a 16-bit stack pointer, 16-bit index register H:X, and BCD arithmetic support. The internal Flash controller supports in-application reprogrammability via the standard HC08 monitor ROM, enabling firmware updates in the field without external programmer hardware. The peripheral set is mapped into the standard HC08 register file for predictable C and assembly coding. Typical applications include HVAC control boards, white-goods motor control, automotive body electronics (mirror/cluster/seat modules), industrial sensor-conditioning boards, and general-purpose 8-bit replacement of legacy HC05/HC11 designs. The wide 3.0-5.5 V supply tolerance lets it share 5 V analog signal-chain rails directly. A key design consideration is supply decoupling: place a 0.1 µF ceramic as close as possible to each VDD/VSS pair, with a bulk 10 µF tantalum or ceramic at the regulator output. Always configure the PLL/oscillator start-up delay and the COP watchdog in code to recover from brown-out or EMI-induced hangs. This page synthesizes distributor stock data, EOL guidance, drop-in alternatives, and practical HC08 design notes not found in the bare manufacturer datasheet - giving procurement and firmware engineers an actionable reference in one place.

MC908GZ32VFAE - 8-Bit 8MHz 32KB Flash MCU | NXP
MC908GZ32VFAE

MC908GZ32VFAE - 8-Bit 8MHz 32KB Flash MCU | NXP

The NXP Semiconductors MC908GZ32VFAE is an 8-bit HC08 microcontroller with a 32KB flash memory, an 8MHz processor, and a 48-pin LQFP package. It is designed around the enhanced M68HC08 CPU08 core and combines 3.3V/5V operation with integrated timers and ultra-low-power characteristics. The supplied distributor information identifies it as an HC08GZ-family MCU suited to embedded control, automotive, and low-cost application systems. The HC08GZ family is part of the broader HC08 microcontroller hierarchy. An MCU integrates a CPU, nonvolatile program memory, data memory, peripherals, and input/output pins into one device, allowing compact embedded products to be built without separate logic devices. The MC908GZ32VFAE therefore serves as a central embedded controller rather than a discrete logic IC or power-management component. Verified product information highlights 32KB of flash, an 8MHz operating speed, integrated timers, and low-power operation. Flash memory retains programmed firmware when power is removed, allowing the MCU to execute a complete embedded-control routine without an external program-memory device. The 48-LQFP (7x7) package provides a defined, inspectable lead arrangement for conventional PCB assembly, while the 3.3V/5V supply description supports integration with systems using either of those operating rails. Typical application domains include automotive body and accessory control, motor or relay sequencing, industrial control panels, sensing systems, and compact embedded products. The CPU08 architecture and timer resources make it suitable for deterministic control tasks that do not require the processing capacity or memory bandwidth of a 16-bit or 32-bit MCU. Firmware should still be tested against the manufacturer datasheet for timing, interrupt, peripheral, and electrical limits. For a new PCB, place decoupling, programming-interface access, clock circuitry, and required pull components according to the manufacturer reference design. Do not assume that a related HC08 or HCS08 part is pin-compatible without checking the exact package pinout and peripheral mapping. The verified data does not provide a current manufacturer PDF URL, detailed electrical limits, memory-map information, or lifecycle declaration, so those fields remain explicitly marked for verification.

MC908GZ32VFJE

MC908GZ32VFJE - 8-Bit HC08 MCU, 32KB Flash, 32-LQFP | NXP

The NXP MC908GZ32VFJE is an 8-bit HC08 family CISC microcontroller with 32KB of embedded Flash program memory, running at 8MHz core clock, housed in a 32-pin LQFP (7x7 mm) package. The part operates from a 3.3V/5V dual-voltage supply, integrating 1.5KB of RAM, 21 general-purpose I/O lines, an internal oscillator, and the classic HC08 instruction set favored in cost-sensitive automotive and industrial embedded designs. An HC08 microcontroller is a member of the Freescale/NXP HC08 8-bit CISC architecture family, itself part of the broader 8-bit MCU hierarchy that includes the HC11 and HC(S)12 ancestors. HC08 devices occupy the cost-optimized, low-pin-count segment of the Freescale 8-bit portfolio and are commonly classified as automotive-grade or industrial-grade microcontrollers depending on qualification. Within a typical embedded system, an MCU sits inside the power management and control subsystem, taking signals from sensors and driving actuators or displays through its GPIO and peripheral set. Key features include 32KB (32K x 8) Flash program memory, 1.5KB of static RAM, 21 GPIO pins, an internal oscillator block to reduce external component count, and 3.3V/5V operating-voltage flexibility that simplifies interface to legacy 5V peripherals. The HC08 CISC core executes each instruction in 2 to 13 bus cycles, delivering adequate throughput for motor control, body-electronics, and simple user-interface tasks at 8MHz. The 32-LQFP (7x7) package supports standard surface-mount assembly lines and provides sufficient thermal performance for industrial temperature ranges. This MCU is widely used in automotive body-electronics modules, industrial control panels, appliance control boards, and low-cost sensor hubs where the HC08 ecosystem, mature toolchain, and long-term NXP/Freescale support outweigh the appeal of newer Cortex-M0 parts. Because the device is now serviced by Rochester Electronics as an authorized continuing-supply source, design teams can maintain legacy platforms without PCB rework. Designers should note that the Flash write/erase endurance (typically 10K cycles per block) and the absence of an on-chip debug port beyond the standard background-debug-mode interface may limit in-field firmware update strategies. The internal oscillator accuracy is typically within a few percent; designs requiring CAN, USB, or precise timing must use an external crystal.

Key features include the enhanced M68HC08 (CPU08) CISC core running at up to 8MHz, 32KB of in-system programmable FLASH supporting field firmware updates, and a rich peripheral set including a serial communication interface (SCI), serial peripheral interface (SPI), and multi-channel timers. The wide 3.3V/5V operating range allows the same design to serve both legacy 5V industrial buses and modern 3.3V logic environments. Technically, the HC08 architecture offers fully static operation, an 8-bit CISC instruction set upward-compatible with the earlier 68HC05, and low-power wait and stop modes for battery-sensitive designs. The GZ family member integrates sufficient on-chip FLASH and RAM to eliminate external memory in typical control applications, simplifying board layout and improving reliability. Typical applications include industrial control panels, appliance control, motor control interfaces, sensor data acquisition nodes, and instrumentation front ends where a rugged 5V-tolerant 8-bit controller is preferred over 32-bit alternatives. Design consideration: verify the exact package suffix, as family variants exist in 48-pin and other QFP footprints; the FUE suffix designates the 64-pin 14x14 mm QFP with extended temperature operation. Plan FLASH programming access and oscillator layout early. This page synthesizes distributor pricing, drop-in family alternatives, and practical design notes not found in the manufacturer datasheet.

It runs at a maximum CPU clock of 8 MHz and is built around the legacy Freescale/NXP HC08 CPU core that targets cost-sensitive, deterministic embedded control. An 8-bit microcontroller (MCU) is a single-chip computer integrating a CPU, program memory (Flash/ROM), data memory (RAM), timers, communication peripherals, and I/O on one silicon die. The HC08 family is a direct ancestor of the modern S08 and S12 families, used widely in automotive body electronics, appliance controls, and industrial sensor interfacing where small code size and proven tool chains matter more than raw throughput. Within the broader taxonomy, MC908GZ48CFAE belongs to: 8-bit MCU -> microcontroller -> embedded processor -> semiconductor IC. The MC908GZ48CFAE communicates with host tools and external devices through a serial monitor ROM, an SCI (serial communications interface), and a 10-bit ADC for analog signal acquisition. The 48 KB Flash supports in-application reprogramming for field firmware updates, while on-chip RAM provides working memory for stack and variables. Its 48-LQFP footprint gives designers ample I/O access for mixed-signal PCBs. Architecturally, the part uses the M68HC08 CPU with a 16-bit internal index/Stack pointer and an 8-bit accumulator, giving efficient C and assembly coding for byte-oriented control loops. The device operates across an extended temperature range suitable for industrial and automotive under-hood subsystems and tolerates a wide supply range compatible with 5 V digital logic. Typical applications include HVAC blower controllers, appliance user-interface panels, small motor drivers, sensor conditioning nodes, and CAN/LIN slave ECUs in cost-optimized vehicle body networks. Engineers select it when they need a stable, long-lifecycle 8-bit controller with a familiar toolchain (CodeWarrior HC08, P&E Micro debugger) rather than a Cortex-M0 equivalent. When prototyping, route the oscillator/PLL pins with short traces to a 4 MHz crystal or ceramic resonator, and decouple VDD/VSS pairs with 100 nF plus bulk capacitors placed within 5 mm of each pair. The HC08 core has no internal voltage regulator on this variant, so an external regulated 5 V rail is required.

As a member of the legacy Freescale/NXP HC08GZ family, the MC908GZ48CFJE targets cost-sensitive embedded control applications that need modest Flash density, multiple timers, ADC, and serial peripherals in a small-footprint surface-mount package. The 'CFJE' suffix denotes the industrial temperature grade, 32-LQFP gull-wing package, and tray packaging. An 8-bit microcontroller (MCU) is a single-chip computer built around an 8-bit data path, integrating a CPU core, non-volatile program memory (Flash or ROM), volatile data memory (RAM), and a mix of on-chip peripherals such as timers, analog-to-digital converters (ADCs), communication interfaces (SCI/SPI/I2C), and general-purpose I/O. Within the semiconductor taxonomy, an MCU is a sub-category of microcontroller -> embedded processor -> digital IC. The HC08 architecture is the successor to the venerable HC05 and remains widely deployed in automotive body electronics, appliance control, and industrial sensor interfaces where deterministic behavior and low cost matter more than raw compute throughput. Key features of the MC908GZ48CFJE include 21 general-purpose I/O lines, an internal oscillator for BOM savings, multiple 16-bit timer channels, a 10-bit successive-approximation ADC, and Flash memory that supports in-application reprogramming for firmware updates in the field. The HC08GZ family adds a CAN 2.0A/B-compatible module (msCAN08) that makes the part particularly well-suited to automotive body and chassis networks where Controller Area Network connectivity is mandatory. Architecturally, the HC08 core uses a von-Neumann memory map with a 16-bit stack pointer, an X-index register, and a HCS08-compatible instruction set, providing object-code compatibility with the broader Freescale 8-bit portfolio. The internal oscillator and on-chip voltage regulator eliminate external clock crystals and most power-conditioning components, while the Flash endurance rating (typically 10K cycles) covers the firmware-update lifetime of consumer and industrial products. Typical applications include automotive body controllers (HVAC, seat control, mirror adjustment), appliance main boards (washing machines, dishwashers, refrigerators), industrial sensor transmitters, low-end motor controllers for small DC and stepper drives, and CAN node endpoints. The combination of Flash, CAN, ADC, and 21 I/O in a 32-LQFP allows a single-chip implementation of most node-level control tasks. When designing with this MCU, allocate sufficient PCB copper under the exposed pad area for thermal dissipation, even though the part rarely dissipates more than a few hundred milliwatts. Decouple VDD/VSS pairs with 100nF ceramic capacitors placed within 5mm of each supply pin, and route the OSC1/OSC2 traces short and guarded if an external crystal is used in place of the internal oscillator.

The NXP MC908GZ60CFJE is an 8-bit HC08 family microcontroller with 60KB of flash program memory and a CISC architecture, offered in a 32-pin LQFP package rated for industrial temperature operation. What is an HC08 microcontroller? An HC08 (also written HCS08) is an 8-bit CISC microcontroller core from NXP/Freescale's legacy M68HC08 family, designed for cost-sensitive embedded control. The HC08 is a member of the broader 8-bit microcontroller taxonomy, sitting between simple 4/8-bit controllers and 32-bit ARM Cortex-M devices, and is commonly used as a stepping stone for engineers moving toward more capable 32-bit platforms. The original HC908 sub-family added on-chip flash memory and a background debug mode (BDM), enabling in-system reprogramming and on-chip debug without an external emulator. Key features of the MC908GZ60CFJE include 60KB of flash, 2KB of RAM, an 8-bit central processing unit running at up to 8 MHz from an internal bus, an internal 5V regulator supporting wide supply operation, an MSCAN (CAN 2.0A/B) controller, an SCI (UART) port, and an SPI interface.

Architecturally, the part implements a standard HC08 CISC core with accumulator-based addressing, indexed addressing with H:X register pair, and a vectored interrupt controller supporting IRQ, SWI, and reset sources. Flash is organized in 512-byte pages for in-application programming, and the internal RC oscillator (with optional crystal reference) eliminates many external timing components. Typical applications include automotive body controllers, HVAC controls, instrument cluster sub-modules, industrial sensor interfaces, building automation nodes, and CAN-based appliance controls where a small footprint and deterministic 8-bit timing fit the requirement. The wide 3V to 5.5V supply tolerance and -40C to +85C industrial range further suit 12V/24V industrial bus environments with local regulation. A key design consideration is that the 8 MHz CPU clock and 60 KB flash put this part at the upper limit of HC08 series; for higher throughput or larger memory you would migrate to the S08 (40 MHz) family such as MC9S08DZ60 or to a Kinetis E-series ARM device. The BDM debug port requires a dedicated 2-pin header for in-circuit development and is not available on smaller packages.

It is designed for embedded control applications that require an 8-bit CPU08 core, integrated program memory, and a compact surface-mount package. The verified distributor data identifies the device as an 8-bit MCU with 60K x 8 Flash and 64-QFP construction. An 8-bit microcontroller is a type of integrated circuit used to execute embedded firmware, read inputs, control outputs, and manage system behavior. The HC08GZ family belongs to the HC08 low-cost, high-performance MCU family and uses the enhanced M68HC08 CPU08 core. Within the embedded-control hierarchy, this MCU combines processor core, Flash program memory, peripherals, and package-level I/O in one device. The principal verified features are the 8-bit data-bus architecture, 8 MHz operating frequency, 60 KB Flash memory, and 64-QFP package. The 60 KB Flash capacity is suitable for firmware that is larger than the memory found in very small 8-bit MCUs, while the CPU08 architecture supports compact embedded control logic. The QFP package provides a surface-mount form factor for automated assembly and multi-board production. The MC908GZ60VFUE-FR is positioned for industrial and embedded products requiring a dedicated 8-bit controller rather than a higher-performance 16-bit or 32-bit MCU. Typical design considerations include confirming the exact peripheral set, I/O mapping, voltage requirements, clock configuration, memory organization, and package footprint against the current manufacturer datasheet before committing a new PCB design. Potential applications include sensor conditioning, simple motor-control logic, keypad and display interfaces, appliance control, industrial instrumentation, and low-cost embedded modules. The controller can centralize fixed-function logic where an 8-bit CPU, 60 KB Flash, and 64-pin integration are sufficient, reducing the need for a larger processor. For a new design, use the manufacturer product page and current datasheet as the authority for pin assignments, electrical limits, memory details, peripheral availability, and qualification information. Distributor pages confirm catalog identity and commercial availability, but they may not expose every engineering parameter needed for schematic or PCB decisions. This page combines verified product identity, source URLs, distributor specifications, engineering guidance, and replacement analysis. It is intended to help engineers evaluate the MC908GZ60VFUE-FR quickly while keeping unverified technical details explicitly unresolved rather than presenting unsupported assumptions as specifications.

MC908JB12JDWE - 8-Bit 6MHz 12KB MCU | NXP | 20-SOIC

The NXP Semiconductors MC908JB12JDWE is an 8-bit HC08 CISC microcontroller with a 6 MHz clock, 12 KB (12K x 8) flash memory, and a 20-SOIC package. It is designed for embedded control applications requiring a compact microcontroller with integrated flash program memory and a 5 V supply. The verified distributor listings identify the device as an MC908JB12-family HC08 microcontroller, making it suitable for legacy industrial, appliance, instrumentation, and control-system designs. An 8-bit microcontroller is a compact embedded-processing component that executes firmware, reads inputs, controls outputs, and manages system timing. MC908JB12JDWE belongs to the HC08 family and uses a CISC-oriented architecture, while its 6 MHz operating speed provides a defined performance baseline for control logic. The 12K x 8 flash organization provides 12 KB of on-chip program storage and supports self-contained firmware in applications that do not require external memory. The main verified characteristics are the 8-bit CPU, 6 MHz clock speed, 12 KB flash memory, 5 V supply, and 20-SOIC package. The 20-SOIC package is a surface-mount SOIC-20 package that is convenient for through-hole-compatible board assembly and automated manufacturing. The package footprint and pin arrangement must still be checked against the manufacturer datasheet before designing a replacement or alternative PCB. MC908JB12JDWE is appropriate for small embedded controllers, including motor and relay-control systems, appliance controllers, simple industrial interfaces, sensor-conditioning systems, and legacy HC08 firmware platforms. Firmware timing, interrupt behavior, memory-map assumptions, and peripheral availability must be validated against the complete manufacturer documentation before production use. A key design consideration is that this is an older HC08 device with a relatively small 12 KB flash budget. Developers should reserve memory for interrupt vectors, constants, calibration data, and future revisions, while using the recommended external clock and reset arrangements from the manufacturer documentation. Verify all timing, I/O, electrical limits, and package details against the official datasheet rather than relying only on distributor summaries. This page consolidates verified distributor specifications, sourcing links, package information, application context, and replacement-search findings. The available search data does not provide enough verified information to claim a pin-compatible replacement, complete pinout, lifecycle guarantee, or every electrical timing parameter without consulting the manufacturer datasheet.
