MC8641VU1000NE

MC8641VU1000NE - 1GHz PowerPC e600 SoC, GbE/SRIO | NXP

The NXP MC8641VU1000NE is a 32-bit Power Architecture (PowerPC e600) single-core system-on-chip running at 1.0 GHz, housed in a 994-ball FCCBGA package (33 x 33 mm). It integrates DDR1/DDR2 memory controllers, four Gigabit Ethernet MACs, PCI Express, and Serial RapidIO (SRIO) interfaces, making it a multi-protocol embedded processor for networking and industrial control. The device operates from 1.05 V core / 1.8 V / 2.5 V / 3.3 V I/O rails across a 0 to 105 °C industrial thermal range and is fab-rated at Rev 3.0 of the silicon. A microprocessor SoC (System-on-Chip) is a single integrated circuit that combines a CPU core, memory controller, and peripheral interfaces on one die. The MC8641 belongs to the PowerPC MPC86xx family of high-performance embedded processors, descending from the Power Architecture instruction set and historically targeted at networking line cards, base stations, and storage controllers. Within the broader semiconductor taxonomy it is classified as an embedded microprocessor (MPU), a sibling category to microcontrollers (MCU) but distinguished by external DRAM, MMU-based virtual memory, and Linux/VxWorks operating-system support rather than firmware-only execution. Key features of the MC8641VU1000NE include one e600 superscalar core with AltiVec SIMD engine, dual DDR1/DDR2 32-bit memory controllers with ECC support, four 10/100/1000 Mbps Ethernet MACs, two PCI Express interfaces, two Serial RapidIO ports, and integrated I2C, UART, SPI, and GPIO peripherals. The 90 nm CMOS process and seven-stage pipeline deliver high IPC efficiency for branchy networking code, while the FCCBGA package supports high-speed SerDes escape without external termination. The e600 core uses a three-issue superscalar out-of-order pipeline with 32 KB I-cache and 32 KB D-cache per core, plus a unified 1 MB L2 cache shared with the platform. Integrated DMA engines and a hardware table-walk unit accelerate packet processing, while the memory controller supports up to 8 GB of DDR2 with ECC. This combination makes it a natural fit for control-plane and data-plane workloads on a single die. Typical applications include networking line cards and routers, where the integrated GbE/SRIO/PCIe interfaces connect directly to fabric and co-processors; telecom base-station controllers; industrial control and factory automation; military/aerospace embedded systems; and storage RAID controllers. The four Gigabit Ethernet MACs in particular make this part well suited to multi-port aggregation and switching line cards. When designing with the MC8641VU1000NE, plan PCB stack-up for the FCCBGA's high-speed SerDes lanes and provide clean 1.05 V core regulation with bulk decoupling near the package. The 33 x 33 mm BGA requires a multi-layer PCB with microvia-in-pad or HDI construction to escape the inner-row balls; design thermal copper under the lid to dissipate the 15-20 W typical power envelope. This page synthesizes distributor pricing, RoHS/compliance status, drop-in pin-compatible alternatives from the MPC86xx family, and practical PCB layout guidance not found in the manufacturer datasheet, giving engineers a single source for sourcing, comparison, and design decisions on the MC8641VU1000NE.

MC8641VU1333JE557

MC8641VU1333JE557 - 2-Core 1.333GHz PowerPC e600 MPU | NXP

The NXP (formerly Freescale) MC8641VU1333JE557 is a dual-core PowerPC e600 microprocessor IC from the MPC86xx host-processor family, operating at 1.333 GHz and packaged in a 1023-ball FCCBGA (33x33 mm). It integrates two 32-bit PowerPC e600 cores with integrated L1/L2 caches, a high-bandwidth on-chip fabric, integrated memory controllers, and multi-gigabit serial I/O. A PowerPC e600 microprocessor is a high-end embedded 32-bit RISC processor core based on the Power Architecture Book E instruction set. PowerPC processors occupy a tier above ARM Cortex-A class cores for many networking and aerospace workloads, while sitting below general-purpose x86 server CPUs; they remain popular in routers, base stations, aerospace guidance, defense signal processing, and storage arrays where deterministic performance, long-term software support, and extended-temperature silicon matter more than raw single-thread IPC. Key distinguishing features of the MPC86xx family include symmetric multiprocessing (SMP) across one, two, or four cores, a coherent L2 cache, integrated DDR2 memory controller with ECC, four integrated GbE MACs, multiple x4/x8 PCI Express lanes, and four multi-protocol RapidIO interfaces. The e600 core adds hardware cryptography accelerators and an MMU supporting 64-bit virtual addressing. Power dissipation in the 1023-FCCBGA part is high enough to require a heatsink and forced airflow at full 1.333 GHz load. Typical applications include multi-gigabit routers, LTE baseband processing cards, radar and sonar front-end DSP co-processors, secure military networking switches, and long-lifecycle industrial control servers where software is locked to the PowerPC ABI. The 33x33 mm FCCBGA is a high-density flip-chip package requiring multilayer PCB with microvia stackups. When designing with this part, plan thermal headroom for 25-40 W class dissipation and use only NXP/Freescale-qualified foundries for PCB assembly; the FCCBGA is not reworkable by hand. Verify pinmap revision letters carefully — revisions 3.0 and later added PCIe Gen2 capability that is software-disabled on earlier revisions.

MC8641VU1500KE

MC8641VU1500KE - PowerPC e600 MPU, 1.5GHz, 994-FCCBGA | NXP

The NXP MC8641VU1500KE is a 32-bit Power Architecture system-on-chip built around a single e600 superscalar core running at up to 1.5 GHz, housed in a 994-ball FCCBGA (33x33 mm) package. The part integrates a DDR1/DDR2 memory controller, four Gigabit Ethernet MACs, PCI Express and Serial RapidIO interfaces, plus AltiVec vector processing for embedded compute workloads. A microprocessor (MPU) is the central execution unit of an embedded computing platform. It fetches instructions, decodes them, performs arithmetic and logical operations, and orchestrates peripherals through on-chip buses. In the embedded hierarchy it sits above microcontrollers in complexity because it relies on external DRAM and sophisticated I/O subsystems; high-performance MPUs target networking, telecom, industrial control, and aerospace applications where deterministic throughput and rich I/O are required. The MC8641 family specifically targets embedded infrastructure requiring multi-protocol I/O and cryptographic acceleration. Key features include the three-issue e600 core with a 7-stage pipeline that handles unpredictable branches efficiently, dual-integrated DDR1/DDR2 controllers with ECC, four 10/100/1000 Mbps Ethernet MACs, and dual PCI Express endpoints. The AltiVec 128-bit SIMD engine accelerates signal processing and crypto workloads. An on-chip security engine supports DES, 3DES, AES, RSA, and elliptic curve operations. The 0 to 105°C operating range suits industrial and extended-temperature environments. Architecturally, the device uses a 90 nm process, multiple voltage rails (1.05V core, 1.1V/1.8V/2.5V/3.3V I/O), and a coherent crossbar fabric that allows future dual-core variants such as the MPC8641D family to share memory. The 33x33 mm FCCBGA is a ceramic flip-chip package suited for high-pin-count designs where signal integrity and thermal performance matter. Power management includes sleep and deep-sleep modes plus per-domain clock gating to reduce consumption when idle. Typical applications include line cards for routing and switching, industrial controllers, defense and aerospace compute platforms, and storage controllers. The combination of multi-gigabit I/O, hardware crypto, and AltiVec SIMD makes it especially well suited to secure networking and packet-processing designs. Production status is Obsolete per the latest distributor listings; remaining stock and franchised brokers should be evaluated for long-term programs. When designing with this device, plan power sequencing carefully because the 1.05V core rail must ramp with respect to the I/O rails, and route DDR signals with matched lengths and controlled impedance to preserve timing margin at 1.5 GHz core speed. Use at least eight decoupling capacitor values (from 10 nF up to 220 uF) distributed under the BGA to suppress transient current demand.

The MPC86xx series historically targeted routers, switches, RAID controllers, and military/aerospace platforms, providing deterministic performance that contemporary ARM SoCs could not match in the late 2000s. Key features include dual e600 cores with AltiVec SIMD support, integrated L1 caches per core, a large shared L2 cache, a 64-bit on-chip coherent fabric, integrated DDR2 memory controller, integrated PCI Express and RapidIO serial interfaces, four Gigabit Ethernet MACs, and hardware-assisted SMP coherency. The 1.05 V core supply reduces power consumption while preserving GHz-class throughput. The architecture combines superscalar out-of-order execution with the AltiVec vector unit, enabling strong performance per MHz on signal-processing workloads. The integrated memory and I/O controllers eliminate the need for a separate northbridge, reducing BOM cost and latency. The platform targets applications where deterministic response and ECC memory integrity matter more than absolute single-thread performance. Typical applications include high-end enterprise routers and switches, telecom baseband processing, network-attached storage controllers, military/aerospace mission computers, industrial automation controllers, and high-performance imaging systems. Drop-in variants exist at different core counts (single-core vs dual-core), cache sizes, and speed grades. When designing with this MPU, allocate a minimum of six PCB layers for power/ground integrity, follow NXP's thermal management guidelines for FCCBGA packages, and use ECC memory to maintain data integrity. Layout must respect the BGA escape routing rules; impedance-controlled differential pairs are required for SERDES lanes.

The NXP Semiconductors MC908AB32CFUE is an 8-bit M68HC08-family microcontroller with a CPU frequency of 8MHz, 32KB of embedded Flash program memory, 512 bytes of EEPROM, and a 64-QFP package measuring 14mm by 14mm. It belongs to the HC08 microcontroller category and combines an embedded MCU core, nonvolatile memory, and integrated peripherals for cost-sensitive embedded control. The relevant product class is a microcontroller rather than a general-purpose processor. A microcontroller integrates a CPU, program memory, data memory, and peripherals such as timers, serial interfaces, interrupt control, and I/O ports on one device. The MC908AB32CFUE is identified as an HC08 MCU with 32K x 8 Flash organization and 8MHz operation, making it suitable for legacy industrial, appliance, instrumentation, and control systems where an established HC08 software and hardware ecosystem is required. The principal verified features are the 8-bit architecture, 8MHz operating frequency, 32KB embedded Flash, 512-byte EEPROM, and 64-QFP package. The combination of Flash and EEPROM allows firmware to reside in program memory while calibration, configuration, or user data can be retained in EEPROM. The exact supply voltage, RAM size, I/O count, timer resources, and electrical timing values are not included in the supplied verified data and must be checked in the manufacturer datasheet before final design release. The MC908AB32CFUE is an End of Life part according to the NXP product-page search result. Engineers should therefore treat availability as constrained and avoid starting new high-volume designs unless product longevity, sourcing, and migration are explicitly approved. A replacement must be checked for package pins, memory-map compatibility, interrupt behavior, peripheral equivalence, clock requirements, and firmware changes rather than selected only by nominal processor speed. Typical HC08 applications include motor and appliance control, simple keypad interfaces, sensor acquisition, low-cost industrial controllers, and legacy embedded products. For a new design, the 8MHz CPU and 32KB Flash provide a modest control platform, while the 512-byte EEPROM is useful for small persistent parameters. The available verified data does not state a specific peripheral set, so feature-level suitability must be confirmed from the datasheet. The key purchasing consideration is supply continuity: the official NXP page identifies the part as End of Life, while distributor listings show the MC908AB32CFUE as an HC08 8-bit, 8MHz, 32KB-Flash, 64-QFP device. Check current distributor inventory, traceability, and authorized-channel status before committing a design. This page consolidates the verified manufacturer and distributor information, practical lifecycle considerations, and the supplied comparison data.

MC908AB32MFUE

MC908AB32MFUE - 8-Bit 8MHz 32KB Flash MCU | NXP

NXP Semiconductors MC908AB32MFUE is an 8-bit HC08 microcontroller rated for 8 MHz operation, with 32 KB of Flash program memory, 1 KB of RAM, and 51 I/O pins in a 64-QFP 14 x 14 mm package. It belongs to the M68HC08 family and uses the enhanced CPU08 core. The NXP product page identifies the device as end of life, so procurement should focus on verified stock rather than new long-term design commitments. A microcontroller is a programmable semiconductor that combines a CPU, nonvolatile program memory, data memory, and peripherals on one integrated circuit. The MC908AB32MFUE sits in the hierarchy MCU → 8-bit microcontroller → M68HC08 family → HC08AB family. It is suited to compact embedded-control systems where an 8-bit architecture, integrated data storage, and a moderate pin count are more useful than high processing bandwidth. The verified device data identifies 32 KB of Flash organized as 32K x 8, 1K x 8 RAM, 51 I/O pins, 8 MHz speed, and a 64-QFP package. A search result also describes 512 bytes of EEPROM, while the broader family data indicates embedded EEPROM or Flash storage for user data. Exact operating voltage, peripherals, timer resources, and electrical limits are not present in the supplied evidence and must be confirmed from the manufacturer datasheet before schematic release. Typical embedded uses include appliance controllers, simple motor-control logic, industrial interfaces, keypad and display systems, and low-cost automation nodes. Its 51 I/O pins provide useful parallel connectivity for sensors, indicators, communications peripherals, and discrete control signals. The 8 MHz CPU and 32 KB Flash footprint favor compact control firmware rather than graphics-intensive, high-bandwidth, or safety-critical workloads. The most important design step is lifecycle planning. Because the NXP page states End of Life, engineers should preserve the footprint, verify stock provenance, confirm suffix-specific temperature and qualification requirements, and assess whether a redesign is preferable to relying on obsolete inventory. Do not infer pin compatibility from package similarity alone; use the exact datasheet pin table and validate every replacement electrically and in firmware. This page consolidates verified manufacturer and distributor information, strict replacement findings, package facts, lifecycle status, and engineering guidance. It separates confirmed values from unavailable parameters so procurement and design teams can identify what must still be checked before purchasing or committing a PCB.

Operating from a 3.3V or 5V supply at 8MHz internal bus speed, it targets cost-sensitive embedded control applications. Originally developed by Freescale Semiconductor and now produced under the NXP brand following the 2015 merger, this part belongs to the legacy M68HC08 line that powered automotive body controllers, white-goods motor control, and consumer device user interfaces throughout the 2000s. An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash/ROM), data memory (RAM), peripheral set (timers, ADC, communications), and I/O pins into one package. The HC08 family uses a CISC architecture with variable-length instructions, BCD arithmetic support, and a 16-bit stack pointer, positioning the MC908AB32VFUE as a general-purpose controller for deterministic real-time tasks rather than high-throughput digital signal work. Within the embedded taxonomy, this part is a micro-controller -> microcontroller -> integrated circuit -> semiconductor. Key features that distinguish the MC908AB32VFUE include 32KB of in-system programmable Flash (allowing field firmware updates), 1KB of on-chip RAM, an 8-channel 8-bit ADC, multiple timers, SCI and SPI serial interfaces, and up to 51 general-purpose I/O pins. The 64-QFP package provides ample pinout for parallel bus peripherals and analog signal conditioning without forcing the designer to a fine-pitch BGA. Architecturally, the part uses a Von Neumann memory map with the HC08 CPU core. Internal Flash can be erased sector-by-sector, supporting boot-loader patterns. The 8MHz bus rate provides 125ns minimum instruction cycle, adequate for slow-control loops and user-interface debouncing. Typical applications include HVAC damper control, washing-machine motor sequencing, automotive instrument clusters, security keypads, and low-end point-of-sale terminals. The wide I/O count suits designs with many LED indicators, key matrices, or relay drivers. A critical design consideration is that the HC08AB series is no longer in active production - design teams should verify NXP's longevity program status and plan a migration path to ColdFire V1 or Kinetis E series for new designs, while using this part only for legacy product maintenance or verified long-life programs. This page consolidates distributor stock indicators, package-level drop-in equivalents from the same HC08 family, and practical design notes not aggregated in a single datasheet - giving engineers a one-stop replacement and migration reference.

The NXP Semiconductors MC908AP16CFAE is an 8-bit HC08 microcontroller with 16KB of flash memory, a 16-channel ADC, SCI/SPI connectivity, and a 48-LQFP package. The verified distributor data identifies an 8 MHz device with 3.3 V/5 V operation, making it a legacy embedded-control solution for cost-sensitive industrial and automotive applications. The MC908AP16CFAE belongs to the M68HC08 family of 8-bit microcontroller units. An MCU integrates a processor core, program memory, data memory, peripheral interfaces, timers, and analog conversion functions on one semiconductor device. This integration allows a compact embedded system to sense inputs, execute control logic, and communicate with external equipment without a separate processor, memory, and interface controller. Verified sources describe the part with 16KB flash, a 16-channel ADC, and SCI/SPI interfaces. The NXP family information also identifies it as part of the low-cost, high-performance M68HC08 family. Its 8-bit architecture and 8 MHz operating speed are appropriate for supervisory, measurement, and control tasks where deterministic peripheral handling is more important than high processor throughput. The supplied sources do not specify RAM size, ADC resolution, pin names, operating-temperature limits, or detailed timing values. The MC908AP16CFAE is listed as End of Life by the NXP product page. Engineers should therefore treat it as a legacy procurement item, not a new-design baseline. NXP search results also reference a discontinuance and replacement overview, but the supplied data does not identify a specific manufacturer-approved drop-in replacement. Pin-compatible alternatives must be validated against the original datasheet, package drawing, memory map, interrupt system, and peripheral electrical limits before substitution. Typical uses include industrial control panels, automotive accessory controllers, sensor-conditioning equipment, motor or actuator management, and low-cost embedded products using SCI or SPI communications. The 48-LQFP package provides a relatively high pin count for legacy control designs, while the ADC supports analog input acquisition. Because detailed memory and pin data are absent from the verified excerpts, the complete pinout and application-specific support network should be checked against the original Freescale/NXP datasheet before layout or firmware reuse. This page consolidates verified distributor listings, lifecycle information, product identifiers, and the available cross-reference context. It does not invent missing electrical specifications or claim that an unreviewed competitor is pin-compatible. For procurement, compare current authorized inventory and ask NXP for the official product-change or replacement documentation.

A microcontroller (MCU) is a single-chip computer containing a processor core, program and data memory, peripherals, and I/O. Within the embedded-systems hierarchy, an MCU is a type of integrated circuit (semiconductor -> IC -> microcontroller). The 8-bit MCU category traditionally trades peak performance for low cost, deterministic interrupt behavior, and ultra-low static power dissipation, making it suitable for cost-sensitive industrial, appliance, and automotive body applications where higher-bit parts are unnecessary. Key features of the MC908AP16CFBE include its 8MHz CPU clock, 16KB Flash program memory, 32 GPIO pins, multi-protocol serial communication (SCI, IRSCI, I²C, SPI), and a 10-bit ADC. The HC08APxA series represents the high-speed oscillator version of the HC08APx family, providing an external crystal/oscillator option for time-sensitive designs. The 44-QFP package is a plastic quad flat pack measuring 10x10mm with gull-wing leads suited for reflow soldering and moderate-density PCB designs. Technically, the CPU08 core uses an enhanced HC05 instruction set with new instructions for improved code density, stack pointer paging for high-level language support, and a 16-bit index register. Memory mapping is linear with 16KB of Flash accessible to the CPU and direct page addressing for fast variable access, while the peripheral modules are mapped into the upper address space. Typical applications include industrial control systems, appliance motor control, automotive body electronics, security and alarm panels, HVAC controllers, and remote-keyless entry receivers. The wide operating voltage (3.3V/5V) and rich peripheral set make this MCU particularly attractive for replacing legacy HC05 designs with code-compatible enhancements. When designing with this part, verify the exact ADC channel count and timer configuration against the latest NXP datasheet revision before committing to layout. The 44-QFP footprint requires careful land-pattern design and reflow profile control for production yields.

The NXP MC908AP16CFBER528 is an 8-bit HC08-family microcontroller with 16KB of Flash program memory, offered in a 44-pin QFP package (10x10 mm). The device integrates a 10-bit ADC and targets embedded control applications that require reliable Flash-based program storage with field-reprogrammability. The "ER528" suffix designates tape-and-reel packaging and a 528-related lead-finish code consistent with NXP legacy ordering options for the M68HC08 line. What is an HC08 microcontroller? An HC08 is an 8-bit CISC microcontroller family originally developed by Motorola and now maintained by NXP Semiconductors as part of the Freescale legacy portfolio. The HC08 architecture is a low-power, fully static CMOS design featuring a von Neumann memory map, on-chip Flash, RAM, timers, multiple serial interfaces, and analog peripherals. It belongs to the broader hierarchy: microcontroller -> embedded MCU -> 8-bit MCU -> HC08 family -> M68HC08AP16 sub-family. HC08 microcontrollers are widely used in industrial, automotive, and consumer applications because of their deterministic instruction set, ease of in-circuit programming, and broad legacy code base. Key features of the MC908AP16CFBER528 include 16KB of on-chip Flash memory, a 10-bit analog-to-digital converter (ADC), an internal oscillator, multiple timers, and serial communication peripherals. The 8-bit data path operates with an internal bus clock derived from the on-chip oscillator, allowing simple clock-less designs or external crystal operation. Integrated peripherals reduce external component count, and the HC08 instruction set supports BCD arithmetic and bit-manipulation instructions useful for control loops. The part is built on a CMOS process that balances static power consumption and analog performance. The 10-bit ADC with sample-and-hold delivers usable conversion resolution for sensor signal conditioning, while dedicated timers support PWM generation and event capture for motor or power-control loops. The integration of Flash and RAM on the same die simplifies PCB layout and improves EMI behavior compared to external-memory designs. Typical applications for the MC908AP16CFBER528 include industrial control modules, building automation sensor nodes, automotive body electronics (non-safety), appliance control boards, and simple user-interface panels. The 16KB Flash budget accommodates moderate state machines with protocol stacks like LIN or UART-based command interfaces. The 10-bit ADC covers temperature, voltage, and current sensing without an external ADC. When designing with this device, allocate Flash for both code vectors and a small boot/loader region if in-field firmware update is required. Ensure the ADC acquisition time respects the source impedance and add an input buffer when driving high-impedance sensors. Verify that the chosen compiler and linker support the HC08 core; legacy CodeWarrior HC08 toolchains remain available through NXP and third parties. This page synthesizes distributor pricing, drop-in same-package alternatives, and practical design notes not found in the manufacturer datasheet - supporting faster sourcing decisions for projects that still rely on the M68HC08 platform.

The NXP Semiconductors MC908AP32ACBE is an 8-bit microcontroller unit (MCU) from the HC08 family with 32KB of FLASH program memory, an 8MHz internal high-speed oscillator, and a 42-pin SDIP (0.600 inch, 15.24mm) through-hole package operating from a 4.5V to 5.5V supply. An 8-bit microcontroller is an integrated circuit that combines a processor core, memory, and peripherals on a single chip, executing instructions on 8-bit data words. Within the power-management and control hierarchy, an MCU sits above discrete logic and below 32-bit application processors, making it the workhorse for embedded control systems. The HC08 family from Motorola/Freescale (now NXP) is a legacy architecture descended from the popular 6805 core, widely used in appliance, automotive, and industrial designs throughout the 1990s and 2000s. Key features of the MC908AP32ACBE include 32KB (32K x 8) of in-circuit-programmable FLASH program memory, 2KB (2K x 8) of RAM, and an internal oscillator rated for 8MHz bus operation, which eliminates the need for an external crystal in many designs. The device provides 30 general-purpose I/O lines, giving ample connectivity for switches, relays, displays, and serial peripherals in through-hole systems. Architecturally, the part is based on the enhanced M68HC08 CPU core with a von Neumann memory map, stack pointer-based C-friendly programming model, and a low-power WAIT and STOP mode set. The internal high-speed oscillator (HS OSC) simplifies clocking, while FLASH non-volatility allows field firmware updates. Because it is a mature HC08 device, mature development toolchains and third-party programmers remain available from legacy-support channels. Typical applications include white-goods appliance control boards, industrial sensor and actuator controllers, automotive body-electronics sub-modules, battery chargers, and legacy-equipment maintenance where a through-hole 42-pin SDIP footprint must be preserved. The 5V supply range makes it directly compatible with legacy 5V industrial logic families. A key design consideration is availability: this is a mature product primarily supplied through aftermarket and authorized excess channels such as Rochester Electronics, so new designs should evaluate the newer S08 family. Verify exact peripheral configuration (timers, ADC, SCI) against the manufacturer datasheet before design reuse.

MC908AP32ACFBE

MC908AP32ACFBE - 8-Bit 8MHz 32KB Flash MCU | NXP

NXP Semiconductors MC908AP32ACFBE is an 8-bit HC08 microcontroller with a CPU08 core, 8 MHz operation, 32 KB of Flash program memory, and a 44-QFP package measuring 10 x 10 mm. The device belongs to the HC08AP high-speed-oscillator family within the M68HC08 product hierarchy. Verified distributor data identifies a -40 °C to +85 °C industrial temperature range and an operating supply range of 4.5 V to 5.5 V. NXP currently labels the product end of life, so procurement planning must account for limited future availability rather than assuming a long active lifecycle. A microcontroller is a programmable semiconductor that integrates a CPU core, memory, digital I/O, and peripherals into one device. The 8-bit MCU category is suited to compact control systems that evaluate logic and operate sensors, actuators, communication interfaces, or human-machine interfaces. Within the broader hierarchy, the MC908AP32ACFBE is an MCU, then a semiconductor, and ultimately an embedded-control component used to execute firmware and coordinate real-time system behavior. The verified feature set identifies 32 KB of Flash memory, 8 MHz clock capability, and 32 I/O ports. Flash retains program code when power is removed, allowing firmware updates and persistent configuration, while the 32 digital I/O pins provide connections for switches, indicators, sensors, and external control logic. The high-speed-oscillator HC08APxA version is distinguished from the related HC08AP family by its oscillator configuration, but detailed peripheral assignments and electrical limits were not included in the supplied source material. Architecture is centered on the enhanced M68HC08 CPU08 core. An 8-bit processor processes one byte per machine-data path and is typically used where deterministic control, modest arithmetic demands, and low system complexity matter more than high computational throughput. The verified 8 MHz operating point supports general-purpose embedded tasks, although real firmware performance depends on instruction mix, memory behavior, peripherals, and interrupt load. Typical uses include compact industrial controllers, appliance interfaces, motor-sequence controls, instrumentation, and small communication modules. For a new design, the NXP end-of-life status should trigger review of the NXP replacement program, last-time-buy timing, and firmware compatibility. Existing production equipment may continue using MC908AP32ACFBE if its 44-QFP footprint and software environment remain unchanged, but a redesign should compare any suggested replacement for memory, peripherals, pinout, voltage, timing, and toolchain compatibility. Layout must preserve the exact 44-QFP land pattern and route decoupling and clock inputs according to the manufacturer data. Because the supplied data does not include a verified pin table, designers must obtain the official package drawing before assigning signals; analogous-looking HC08 devices must not be assumed interchangeable. This page combines verified lifecycle, memory, clock, package, temperature, commercial, and cross-reference information with explicit engineering caveats. It is designed to support sourcing decisions while avoiding unsupported assumptions about electrical limits, pin functions, peripherals, or unverified replacement devices.

The MC908AP64CBE is therefore a general-purpose 8-bit embedded MCU rather than a discrete logic IC or analog regulator. The verified product data highlights a 64K x 8 flash organization, meaning 64K eight-bit storage locations, and an 8MHz operating speed. The 42-pin PDIP package supports conventional through-hole PCB assembly and provides the external signal and power connections required by the HC08 device family. The verified distributor descriptions also associate the part with a 10-bit ADC application feature, although detailed ADC operating conditions are not provided in the supplied data. Do not infer resolution, accuracy, or conversion timing beyond that explicit 10-bit ADC association. MC908AP64CBE can be used in industrial control, appliance control, instrumentation, low-cost embedded products, and legacy embedded systems where a dedicated 8-bit controller is preferred over a higher-performance processor. The 64KB flash capacity provides room for firmware and application logic, while the 8-bit CPU architecture can simplify resource-constrained control loops. Engineers should verify the complete pinout, supply limits, clock configuration, memory map, and peripheral behavior against the official Freescale or NXP datasheet before finalizing a new design. Because this is a legacy DIP MCU, PCB decisions should be driven by package outline, pin numbering, programming method, and signal requirements rather than only the base part number. A distributor listing may show the HC08 family, flash size, speed, and package, but it does not replace a full manufacturer datasheet for production qualification. Confirm authorized sourcing and current lifecycle status during procurement. This page consolidates verified distributor specifications, sourcing context, and practical replacement-selection guidance for MC908AP64CBE. Pricing, complete pin names, detailed ADC specifications, voltage limits, and verified drop-in alternatives are not available in the supplied data and must not be guessed.

MC908AP64CFAE - 8-Bit 8MHz 64KB MCU | NXP | Automotive

NXP Semiconductors MC908AP64CFAE is an 8-bit HC08 microcontroller operating at 8 MHz, with 64 KB flash memory, 2 KB RAM, an 8-channel 10-bit ADC, and LIN capability in a 48-LQFP 7x7 mm package. It is positioned for automotive and industrial control systems where compact embedded control, analog measurement, and serial connectivity are required. A microcontroller is a programmable embedded-control component that combines a CPU, memory, peripherals, and input/output functions on one integrated circuit. The MC908AP64CFAE belongs to the HC08 family of 8-bit devices and is designed for cost-sensitive control platforms that need deterministic peripheral integration without a high-performance processor core. Its 64 KB flash provides program storage, while 2 KB RAM supports working data and stack operations. The key feature set includes an 8 MHz CPU08 microcontroller core, 64 KB flash, 2 KB RAM, an 8-channel ADC identified by distributor data as a 10-bit ADC, and LIN capability. The 48-LQFP 7x7 mm package provides a substantial lead count for external peripherals and automotive or industrial signal connections. Exact pin names, voltage limits, clock details, ADC timing, and electrical limits should be confirmed in the NXP manufacturer documentation. Because this is an embedded MCU rather than a power semiconductor, its architecture is centered on firmware execution and peripheral connectivity. The ADC can support sensor acquisition and threshold-based control, while LIN capability can support low-cost vehicle or distributed industrial networks. Firmware, external clocking, memory programming, and peripheral configuration must be matched to the system requirements before production release. Typical applications include automotive body-control modules, LIN-connected nodes, industrial sensor controllers, actuator controllers, compact embedded systems, and low-cost control panels. The 8-bit architecture is appropriate when the workload is mainly I/O, state-machine, timer, and analog-signal processing rather than intensive computation, graphics, or high-bandwidth communications. Design consideration: place the MCU power, decoupling, clock, reset, and debug or programming connections according to the NXP datasheet reference layout. Confirm package pin compatibility and peripheral mappings before substituting any candidate. This page combines verified manufacturer and distributor information with practical design context, comparison criteria, and application guidance.

MC908AP64CFAER - HC08 8-Bit MCU, 64KB FLASH, 48-LQFP | NXP

The NXP (formerly Freescale) MC908AP64CFAER is a member of the HC08AP family of 8-bit microcontrollers built around the enhanced M68HC08 central processor (CPU08). The device integrates 64KB of FLASH program memory, runs at 8MHz, and is housed in a 48-pin LQFP (7x7 mm) package. It targets low-cost, high-performance embedded control with on-chip 10-bit ADC support. A microcontroller (MCU) is a single-chip computer that integrates a CPU, memory (program FLASH and data RAM), and programmable I/O peripherals. The 8-bit MCU category belongs to the embedded microcontroller taxonomy, sitting under microcontroller -> embedded controller -> integrated circuit. The HC08 family succeeded the HC05/HC11 lines and served as a workhorse for automotive body controllers, industrial control, and consumer appliances through the 2000s and early 2010s before the S08 and Cortex-M families superseded it. Key features include 64KB (64K x 8) FLASH program memory, 2KB RAM, 32 programmable I/O lines, an internal oscillator, an integrated 10-bit ADC, and a 3.3V/5V operating range. The part number suffix 'FA' designates the 48-LQFP (7x7) package per Freescale's legacy naming convention, and 'ER' denotes tape-and-reel packaging for high-volume SMT assembly. Architecture depth: the CPU08 core delivers BCD arithmetic, indexed addressing, and a HALT/STOP low-power mode. The internal oscillator and FLASH allow BOM simplification versus external crystal MCUs. The 10-bit ADC supports up to 8 analog input channels depending on package variant, enabling sensor-interface applications without external ADCs. Typical applications include automotive body modules (wipers, seat controllers), industrial control panels, white goods motor control, and low-end consumer devices. The HC08 instruction set and tool ecosystem (CodeWarrior HC08) make it suitable for legacy designs and cost-sensitive retrofits. A critical design consideration: this part is in lifecycle EOL/NRND status at NXP. Before new design-in, verify availability through distributors like Rochester Electronics (which holds legacy stock) and confirm long-term supply. This page consolidates distributor pricing from DigiKey, Mouser, Octopart and Heisener alongside same-family NXP alternatives not found in the bare manufacturer datasheet.
