MCF54453VR266 - ColdFire V4 32-bit MPU, 266MHz, 360-TEPBGA | NXP

The NXP MCF54453VR266 is a 32-bit ColdFire V4 microprocessor (MPU) running at 266 MHz, housed in a 360-ball TEPBGA (23x23 mm) package. It integrates a rich set of connectivity peripherals including 10/100 Ethernet MAC, USB On-The-Go (OTG), and a PCI bus controller, designed for high-performance embedded control applications that require extensive wired connectivity. An MPU (microprocessor unit) is a CPU-centric integrated circuit that typically requires external memory for program and data storage, distinguishing it from a microcontroller (MCU) that integrates flash/RAM on-chip. The MCF5445x family targets power-conscious embedded designs where the application code and operating system exceed internal memory limits; ColdFire V4 implements a variable-length RISC architecture (ColdFire instruction set) that maintains software compatibility with the legacy 68k family while delivering modern performance per MHz. Key features include a 266 MHz ColdFire V4 core with MMU (memory management unit) for full virtual memory operating systems such as Linux or MQX, ROMless external memory bus supporting SDRAM, SRAM, and flash, dual 10/100 Fast Ethernet controllers with MII/RMII interfaces, USB 2.0 On-The-Go with integrated PHY, 32-bit PCI 2.3 bus, four 32-bit timer units, multiple UARTs (including SCI), I²C, and an interrupt controller. Operating voltages are 1.8V core / 2.5V / 3.3V I/O according to the FindIC specifications record. The ROMless designation indicates external flash must be connected to boot the device. Architecturally, the ColdFire V4 core uses a 7-stage pipeline with branch prediction, supporting 32-bit addressing and DSP-like MAC instructions for signal processing. The MMU enables demand-paged virtual memory, allowing full Linux kernels (uClinux, MQX) and complex RTOS deployments. Integrated peripherals are mapped through the ColdFire peripheral bus with a unified interrupt controller. Typical applications include industrial automation controllers, point-of-sale (POS) terminals, networked printers, factory-floor gateways, medical instrumentation with connectivity, and embedded Linux single-board computers. The combination of Ethernet + USB OTG + PCI in a single package allows compact designs where multiple external bridge chips would otherwise be needed. Design considerations include careful PCB layout for the 360-ball BGA, multiple decoupling rails for 1.8V/2.5V/3.3V domains, boot configuration via external flash, and thermal management given the 23x23 mm package thermal characteristics.

The principal verified characteristics are a 266 MHz operating frequency, 32-bit architecture, one CPU core, a 32-bit data-bus width, and compatibility with 1.8 V, 2.5 V, and 3.3 V rails. Its 360 TEPBGA package offers extensive connectivity for embedded systems, but every pin assignment, signal-routing requirement, and thermal condition must be checked against the official MCF54454 datasheet before layout or firmware deployment. MCF54454AVR266 can suit industrial controllers, networked equipment, automation systems, communications equipment, and real-time embedded control platforms. Its 32-bit processing architecture is appropriate for firmware combining peripheral control, protocol handling, data acquisition, and supervisory logic. The exact memory capacity, peripheral set, clocking requirements, and electrical limits are not available in the supplied verified results and must not be inferred from the MPN. The critical design consideration is package-level implementation. A 23 x 23 mm, 360-terminal TEPBGA requires multilayer PCB routing, exact land-pattern compliance, controlled escape routing, and careful via placement. Confirm the manufacturer pinout, recommended PCB stack-up, decoupling network, exposed thermal strategy, and manufacturing tolerances before releasing artwork. This page consolidates verified package and processor listings, source links, sourcing limitations, and engineering context beyond a distributor search result.

MCF54454CVR200

MCF54454CVR200 - ColdFire V4 MPU, 200MHz, 360-PBGA | NXP

The NXP (formerly Freescale) MCF54454CVR200 is a 32-bit ColdFire V4 microprocessor running at 200MHz, housed in a 360-pin TE-PBGA (23x23) package and announced as End of Life per the NXP product page snapshot retrieved 2026-10-18. The MCF5445x family integrates a rich connectivity peripheral set including 10/100 Ethernet with hardware MAC, USB On-The-Go (USB OTG), PCI, I2C, SPI, SSI and multiple UART/USART channels, addressing power-conscious industrial and embedded control applications. Core highlights are 200MHz ColdFire V4 with VFP (vector floating-point) support, up to 32KB SRAM, 132 general-purpose I/Os, ROMless external memory interface, and 1.8V/2.5V/3.3V mixed-voltage I/O with 1.35V to 3.6V core supply range. What is a ColdFire microprocessor? ColdFire is a 32-bit variable-length RISC ISA descended from the Motorola 68000 family, optimized for embedded systems requiring high code density, deterministic interrupt latency and low active power consumption. Within NXP's processor taxonomy ColdFire sits between 8-bit MCUs and the higher-tier Power Architecture (PowerPC/e200) cores, giving embedded designers an upgrade path from 8/16-bit control without moving to a full Linux-capable MPU. The V4 subfamily is the highest performance ColdFire generation and adds a hardware VFP unit, DDR SDRAM controller, and integrated Ethernet+USB+PCI connectivity. Key differentiators include the integrated triple-role connectivity (Ethernet MAC + USB OTG + PCI in a single chip), on-chip DMA controller for offloading memory moves, watchdog timer, JTAG/BDM debug interface, and support for DDR SDRAM and NAND flash boot. The TE-BGA 360 package with 23x23 body and 1mm pitch provides ample I/O for external bus and connectivity peripherals while remaining PCB-manufacturable on 4-layer FR-4 stack-ups. Architecturally the MCF5445x uses a superscalar ColdFire V4 core with hardware floating-point and a unified cache hierarchy feeding an enhanced SRAM/SDRAM controller, which avoids the latency penalty of discrete memory interfaces. The crossbar-based system bus arbitrates simultaneous DMA, Ethernet and USB transactions, suiting multi-protocol gateways that must serve real-time industrial traffic without dropping packets. Typical applications include industrial control and Human-Machine Interface (HMI) panels, factory automation PLCs, networked point-of-sale terminals, multi-protocol gateways, USB-connected peripherals, and embedded imaging or motion control nodes. The wide connectivity set allows a single chip to bridge Ethernet, USB and legacy serial fieldbus segments. When designing with this part, allocate sufficient PCB real-estate for the 360-ball TE-BGA and verify the DDR controller's IBIS/termination network matches the chosen SDRAM. Customers should also check the NXP PCN/Discontinuance notice for last-time-buy windows, second-source options, and recommended migration devices.

Connectivity peripherals encompass I2C, SPI, SSI (Synchronous Serial Interface), and UART/USART channels. An MMU (Memory Management Unit) is included for running protected operating systems, and the integrated DMA (Direct Memory Access) controller offloads data movement from the core. An FPU (Floating-Point Unit) is included in this variant for hardware-accelerated single-precision floating-point math. The ColdFire V4 core uses a 7-stage pipeline with branch prediction and a unified L1 cache, achieving 1.56 Dhrystone MIPS per MHz at the 266 MHz top speed. Operating voltages include 1.8V, 2.5V, and 3.3V rails, allowing flexible I/O interfacing with external SDRAM, NOR flash, and peripheral devices.

MCF54455VR266 - Coldfire V4 32-Bit MPU, 266MHz, 360-TEPBGA | NXP

The NXP MCF54455VR266 is a 32-bit ColdFire V4 microprocessor running at 266 MHz in a 360-ball TEPBGA package (23x23 mm) with ROMless boot. It integrates Ethernet, USB OTG, and PCI connectivity alongside a memory management unit (MMU) for protected operating systems. A microprocessor (MPU) is a single-chip CPU that integrates the core, cache, memory controller, and a broad set of peripherals on a single die. The ColdFire V4 architecture is a 32-bit RISC-style ISA derived from the original Motorola 68000 family, offering strong code density, deterministic interrupt latency, and wide peripheral integration. Within the embedded hierarchy, the MCF5445x sits between microcontrollers (less integration, easier PCB design) and application processors (higher GHz cores, complex SoCs), targeting mid-range industrial and connectivity-rich designs that need TCP/IP stacks and rich I/O without an external MMU companion chip. Key specifications include a 266 MHz V4 core with MMU, ROMless external memory interface supporting DDR/SDRAM, 10/100 Ethernet MAC, USB 2.0 On-The-Go, a PCI v2.3 bus controller, four SSI/I2S audio interfaces, three UARTs, two I2C buses, and a FlexCAN module. The 360-TEPBGA package exposes a wide external memory bus for SRAM, NOR flash, and SDRAM boot, supporting systems that need larger code storage than typical internal-flash MCUs provide. Typical applications include industrial control with TCP/IP connectivity, factory automation nodes requiring deterministic Ethernet, networked point-of-sale terminals, HVAC control with remote management, medical instrumentation with PCI expansion, and embedded gateways handling USB peripherals. The combination of MMU + Ethernet + USB OTG also supports Linux/uClinux deployments where protected address spaces and a full TCP/IP stack are mandatory. A key design consideration is that the ROMless variant requires an external boot flash, so engineers must add an 8- or 16-bit boot ROM (or a managed NAND boot) before main firmware executes. Designers should also pay attention to 1.8V/2.5V/3.3V mixed-I/O power sequencing to avoid latch-up on the SDRAM interface.

The integrated security engine (SEC) accelerates DES, 3DES, AES, SHA-1/MD5 — purpose-built for secure networked control. Architecturally, the V4E core supersedes V4 with branch acceleration, larger TLBs, and improved DMA-coupled peripheral throughput. The 200 MHz core drives up to 305 MIPS sustained, with deterministic interrupt latency suitable for real-time Ethernet/control loops. On-chip 32 KB SRAM and external SDRAM/DDR-style memory controller (plus FlexBus for NAND/NOR/FPGA) deliver headroom for protocols like uClinux, RTEMS, or VxWorks with full MMU protection. Typical applications include industrial Ethernet gateways, factory-automation PLCs with secure remote management, networked printers and multifunction peripherals, building-automation controllers, smart-grid concentrators, point-of-sale / payment terminals, and embedded web/Ethernet servers. The dual-Ethernet + PCI combination is the classic industrial-control signature; the encryption accelerator answers the secure-management slot. When designing with the MCF5470VR200, plan for a 6–10 layer PCB to fan out the 1.00 mm-pitch 388-ball grid and place at least four 0.1 µF/10 µF decoupling groups near each power quadrant (1.5 V core, 2.5 V/3.3 V I/O). The part is now NRND, so RoHS-compliant lead-free assembly is mandatory and a second-source plan is recommended for new designs.

The NXP (Freescale) MCF5474VR266 is a 32-bit ColdFire V4e microprocessor (MPU) operating at 266 MHz with integrated MMU and FPU, housed in a ROMless 388-pin PBGA (27 x 27 mm) package. It belongs to the MCF547x family of network-connected control processors. A microprocessor unit (MPU) is the central computing engine of an embedded system, sitting above microcontrollers in the hierarchy by offering higher clock speeds, external memory interfaces, and richer peripherals while requiring external program memory. The ColdFire V4e architecture is an enhanced 32-bit RISC-derived CISC-compatible core that adds a memory management unit (MMU) and a floating-point unit (FPU) directly on the core, enabling running of high-level operating systems such as Linux. Key features of the MCF5474VR266 include the 266 MHz V4e core with hardware divide, MMU, and FPU; dual Ethernet media access controllers (MACs) for redundant or dual-port networking; a PCI controller for host/expansion connectivity; a hardware encryption accelerator supporting secure communications; and multiple serial interfaces including USB, I2C, UART, and DMA-capable serial peripherals. Architecturally, the device couples the ColdFire V4e execution core with a system bus that services the on-chip peripherals and an external bus interface, allowing ROMless operation where boot code and applications are fetched from external flash or SDRAM. The ROMless design (denoted by the V in the part number suffix) gives system designers full control of code storage, which suits scalable networking products. The hardware encryption accelerator offloads DES/3DES/AES-class operations from the core, sustaining line-rate secure throughput in network control planes. Typical applications include industrial Ethernet switches and gateways, networked building and process control, print and imaging systems, and secure remote-management nodes where dual Ethernet plus PCI and cryptographic acceleration are required. A key design consideration is supply architecture: the MCF5474VR266 operates from dual 2.5V (core) and 3.3V (I/O) rails, so a proper power-sequencing and decoupling plan is required. Thermal design should also budget for the power dissipated by the 266 MHz core in the 27 x 27 mm PBGA. This page adds information gain beyond the datasheet by synthesizing distributor inventory, pin-compatible family alternatives, lifecycle status (NRND), and practical drop-in replacement guidance in one place.

An MPU (microprocessor unit) is a CPU-centric chip that requires external RAM, ROM, and peripherals to form a complete system, distinguishing it from a microcontroller (MCU) which integrates memory and I/O on-die. The ColdFire V4e ISA implements a streamlined 32-bit RISC-style instruction set derived from the original Motorola 68000 family, optimized for high code density in networking and embedded control. Within the broader NXP taxonomy, the MCF547x belongs to the high-tier ColdFire segment above MCF52xx and MCF53xx, sitting just below PowerQUICC parts. The PBGA-388 package has a junction-to-ambient thermal resistance suitable for industrial convection-cooled enclosures without forced airflow. Key features of the MCF5474ZP266 include 32 KBytes of unified instruction cache (I-Cache) and 32 KBytes of SRAM, a DDR SDRAM controller supporting up to 133 MHz operation, 8-channel DMA, four 32-bit timers, programmable interrupt controller, and integrated security through hardware encryption (DES, 3DES, AES, SHA, MD5, RC4). The dual Ethernet ports enable router, gateway, and industrial switch designs without external MACs, while the PCI controller provides high-bandwidth expansion to ASICs or co-processors. Peripherals such as DMA, PWM, and a watchdog timer (WDT) further reduce external component count. The MCF5474ZP266 is built on a 0.13 um CMOS process, runs from a 1.5 V core / 2.5 V and 3.3 V I/O supply, and provides 99 general-purpose I/O pins for board-level interfacing. Operating temperature range is -40 C to +105 C (industrial grade), making the device suitable for harsh environments. NXP has designated this part as NRND (Not Recommended for New Designs) in favor of newer ColdFire and i.MX parts, with Rochester Electronics listed as a continuing-source distributor for legacy maintenance. Typical applications include industrial Ethernet gateways and PLCs, networked factory automation controllers, point-of-sale and secure transaction terminals, networked printers and imaging controllers, and telecom/datacom access equipment. The combination of MMU (for embedded Linux/uClinux), FPU (for control algorithms), and hardware encryption makes the device attractive for security-sensitive connected-control products that need a deterministic real-time response. When designing with the MCF5474ZP266, allocate at least four PCB layers for signal integrity on the DDR SDRAM bus, maintain the 50 ohm controlled impedance on Ethernet pairs, and place bypass capacitors within 5 mm of every power pin. Because of NRND status, system architects selecting this part for new designs should consult NXP PCN (Product Change Notice) documentation and confirm longevity support with the franchised distributor or authorized aftermarket supplier.

Key features include the enhanced ColdFire V4e core with memory management unit and emulated hardware floating-point acceleration, two integrated Ethernet media access controllers (MACs) for dual-port networking, a PCI controller for peripheral expansion, and a hardware encryption accelerator supporting secure communications. These connectivity peripherals dramatically reduce external component count in gateway and bridge designs. Architecturally, the V4e core is a variable-length RISC implementation with a six-stage pipeline, and the double-reduced instruction execution improves instruction throughput at the 266 MHz operating frequency. The internal system bus connects on-chip peripherals to the core with DMA support across multiple channels, offloading data movement from the CPU in high-bandwidth packet-processing workloads. Typical applications include industrial Ethernet switches and gateways, networked control systems, protocol converters, secure communication nodes, and embedded PCI-based equipment. The dual Ethernet ports and encryption acceleration make it a natural fit for secure industrial gateways where both throughput and data protection matter.

MCHC11F1CFNE2 - 8-Bit HC11 MCU, 1KB RAM, 512B EEPROM | NXP

The NXP MCHC11F1CFNE2 is an 8-bit HC11 CISC microcontroller unit (MCU) housed in a 68-pin PLCC (Plastic Leaded Chip Carrier) J-Lead package measuring 24.21 x 24.21 mm. It operates at a core clock speed of 2 MHz, integrates 1 KB of SRAM and 512 bytes of EEPROM, and is a ROMless variant (no internal mask ROM; program memory is supplied externally). The device provides 30 general-purpose I/O lines and includes an on-chip EPROM/OTP option that historically supported 512 bytes of user-programmable non-volatile storage alongside the EEPROM. What is an HC11 microcontroller? The HC11 is a classic 8-bit CISC (Complex Instruction Set Computer) microcontroller family originally developed by Motorola (later Freescale, now NXP). It belongs to the broader category of microcontrollers (MCUs) within the semiconductor hierarchy: MCU -> Microcontroller -> Embedded Processor -> Semiconductor Device. The HC11 architecture is known for its rich instruction set, on-chip peripherals (timers, A/D converter, serial communication interfaces), and flexible memory configuration, which made it popular for automotive and industrial embedded designs from the 1980s onward. Key features of the MCHC11F1CFNE2 include the 2 MHz bus frequency derived from an external oscillator, low-power operating modes for battery-sensitive applications, multiple serial interfaces (SCI and SPI), and a robust interrupt controller. The ROMless configuration allows designers to pair the MCU with external program memory, which was commonly used for prototyping and low-volume automotive/industrial control applications where in-system updates to firmware were required. The internal architecture combines a CPU core, 1 KB of static RAM for scratchpad and variable storage, 512 bytes of byte-erasable EEPROM for non-volatile parameter storage, and a peripheral subsystem including timers, an 8-channel 8-bit A/D converter, and serial communication peripherals. The 2 MHz clock supports deterministic execution suitable for real-time control loops in automotive ECUs. Typical applications include automotive body controllers, instrument cluster electronics, HVAC controls, industrial sensor interfaces, and legacy industrial automation controllers. The wide operating temperature range and PLCC packaging make the part especially suited for harsh-environment automotive applications. When designing with this device, ensure that the external oscillator and reset circuitry follow the HC11 reference manual recommendations. Because the part is ROMless, the designer must also select a compatible external memory interface; the boot mode selected at reset determines how the part fetches its initial program.

The NXP MCHC11F1CFNE5 is an 8-bit HC11 microcontroller IC delivering 5MHz CPU performance in a 68-pin PLCC package with surface-mount J-lead termination. It is a ROMless variant of the legacy M68HC11F1 family, supplied in the FN-suffix 68-LCC (J-Lead, 24.21 x 24.21 mm) outline, and is targeted at embedded control designs requiring an external memory option. An HC11 microcontroller is a member of the Motorola/Freescale/NXP 6800-derived 8-bit M68HC11 family of microcontrollers — historically one of the most widely deployed 8-bit MCU architectures for automotive body electronics, industrial control, and consumer embedded designs. The HC11 combines a CPU12-like instruction set with on-chip peripherals such as timers, serial communications interface (SCI), serial peripheral interface (SPI), analog-to-digital converters, and general-purpose I/O. 'ROMless' indicates the device has no internal program memory and relies entirely on external EPROM/Flash for code storage, simplifying prototyping and field-update workflows. Key features of the MCHC11F1CFNE5 include a 5MHz maximum bus clock, an 8-bit data path with 16-bit addressing capability, 1KB of on-chip RAM (per the Mouser catalog summary), 512 bytes of on-chip EEPROM, multiple 8-bit I/O ports, and a comprehensive interrupt and reset architecture. The device integrates an SCI, an SPI, a programmable timer system, pulse-width modulation channels, and an 8-channel 8-bit ADC. Peripherals are accessible via a unified memory-mapped register interface. Architecturally the MCHC11F1CFNE5 uses the HC11 CPU core with a 16-bit internal index/data structure (X, Y, SP, PC), allowing C and assembly compilers familiar with the legacy Freescale toolchain to target it directly. The ROMless memory map provides a 64KB linear address space and dedicated modes (single-chip, expanded, special test) selectable via the MODA/MODB pins. An on-chip oscillator with divide-by-256 option supports low-power standby. Typical applications span automotive body controllers, HVAC actuators, industrial sensor concentrators, legacy industrial automation controllers, and field-replaceable instrumentation requiring an external program memory interface. Designers maintaining installed HC11 fleets will find this part functionally identical to the earlier MC68HC11F1-series devices. When porting older designs, designers should verify the MODA/MODB mode pins are strapped for expanded-multiplexed mode to enable the external memory bus, and confirm the E-clock rate does not exceed 5MHz at the chosen VDD.

MCHC705JJ7CPE - 8-bit HC05 MCU, 6KB OTP, 2.1MHz, DIP-20 | NXP

The NXP (formerly Freescale) MCHC705JJ7CPE is an 8-bit HC05-family microcontroller with 6KB of one-time-programmable (OTP) program memory, 224 bytes of RAM, and 14 I/O pins, housed in a 20-pin PDIP (0.300 inch) through-hole package. The device runs at a 2.1 MHz bus clock from an internal oscillator and is targeted at cost-sensitive, low-volume embedded control applications where simple 8-bit processing, in-system programming via the monitor ROM, and a DIP footprint simplify prototyping and field service. An 8-bit microcontroller (MCU) is a single-chip computer built around an 8-bit data path, on-chip program memory, RAM, peripherals, and I/O. It belongs to the broader hierarchy: microcontroller -> embedded processor -> semiconductor -> electronic component. The HC05 line from NXP/Freescale is one of the longest-lived 8-bit families, designed for deterministic, low-power control tasks that do not need the throughput of a 16- or 32-bit core. Compared with modern ARM Cortex-M0 parts, HC05 MCUs trade raw performance for simplicity, an easy-to-write instruction set, and a small memory footprint that fits mass-market appliance and consumer applications. Key features of the MCHC705JJ7CPE include 6KB (6144 bytes) of OTP program memory, 224 bytes of on-chip RAM, 14 general-purpose I/O lines, an internal oscillator that removes the need for an external crystal on many designs, a serial communications interface (SCI) for UART-style asynchronous serial, a 16-bit timer with capture and compare, and a five-channel 8-bit ADC. The on-chip monitor ROM provides in-circuit serial programming for development and field updates. The 'C' temperature grade supports 0C to +70C operation, while the 'E' suffix denotes the -40C to +125C extended grade - a key discriminator when selecting between suffixes in the family. The device uses the legacy HC05 core with a von Neumann memory map. The OTP memory is one-time programmable, so firmware must be fully verified before production programming; for high-volume runs, the masked-ROM equivalent (MCHC705JJ7MPE or similar) is more economical. The internal oscillator and the absence of an external bus make the device suitable for single-chip-mode applications where the MCU is the only active logic on the board. Typical applications include white-goods motor drivers, small appliance controllers, simple sensor interfaces, security and alarm panels, remote-control transmitters, and educational/development boards where a through-hole DIP package aids manual soldering and lab rework. Designers should note that OTP memory cannot be re-programmed, so a debug-and-reflash workflow typically uses the windowed or EPROM-emulator sibling (MCHC705JJ7PBE) during development, with the OTP device reserved for production. When designing with the MCHC705JJ7CPE, ensure adequate decoupling on VDD/VSS (typically 100 nF plus bulk), keep the RESET pin high through a pull-up with optional capacitor for POR, and verify that the chosen I/O lines are 5V-tolerant when interfacing 3.3V peripherals. Trade-off: the 2.1 MHz clock caps instruction throughput but minimizes EMI and power consumption versus faster HC08/HC11 derivatives. This page synthesizes distributor pricing, OTP-versus-mask trade-offs, and practical design notes not found in the legacy NXP datasheet alone.
