MC68340FE16VE 개요

The NXP MC68340FE16VE is a high-performance 32-bit integrated microprocessor from the M683xx family, featuring an enhanced M68000-compatible CPU32 core, dual-channel 32-bit DMA, two timer modules, a serial communications interface, and a parallel port, all integrated on a single die. The -FE16VE suffix designates a 16.78 MHz CPU clock, a 3.3 V supply, and a 144-pin ceramic CQFP package (26.77 x 26.77 mm) suited for extended-temperature industrial and legacy embedded systems.

An integrated MPU (microprocessor unit) is a CPU-centric device that relies on external memory and peripherals, sitting above microcontrollers in the embedded-computing taxonomy: MPU -> 32-bit processor -> CPU -> integrated circuit. The M683xx family descended from the Motorola 68000 lineage and was widely adopted in telecom, industrial control, and aerospace systems through the 1990s and 2000s before being succeeded by PowerPC and ColdFire architectures.

Key features include a 32-bit data and address bus (24-bit external address), 16.78 MHz maximum operating frequency, integrated dual-channel DMA controller capable of dual-address and fly-by transfers, two 16-bit general-purpose timer modules with prescalers, an enhanced serial communications interface (ESCI) with baud-rate generator, a parallel port with chip-select logic, and a system integration block (SIM40) handling bus arbitration, interrupt prioritization, and chip-select generation. The 'FE' temperature grade supports 0C to +70C operation.

Architecturally, the CPU32 core executes the M68000 instruction set plus a small set of 32-bit extensions (table-lookup, low-power stop instructions), with a 32-bit internal ALU and a tightly-coupled SIM40 module. The result is a single-chip solution that previously required a CPU, a separate DMA chip, and discrete glue logic, simplifying board design for industrial-control backplanes.

Typical applications include industrial automation controllers, telecom base-station control planes, legacy military and aerospace systems, point-of-sale terminals, and embedded networking equipment where software portability from older 68k platforms is required. Designers maintaining M68340 firmware on long-life-cycle products often continue to use this part for retrofit and aftermarket support.

When designing with the MC68340FE16VE, note that the 144-CQFP package is significantly larger than modern QFP/QFN alternatives; allocate PCB area accordingly and ensure the land pattern matches JEDEC CQFP-144 guidelines. Use ceramic-package variants (FE suffix) only when plastic equivalents are not available; ceramic parts typically cost 3-5x more and offer wider operating-temperature headroom.

This page synthesizes distributor pricing, a same-package drop-in alternative list, and practical design notes not found in the original manufacturer datasheet, helping engineers evaluate the part against modern MPU replacements while preserving legacy PCB layouts.

일반적인 애플리케이션

MC68340FE16VE 적합 용도: 6 애플리케이션s: Industrial Automation Controllers, Telecom Base Station Control Plane, Legacy Aerospace / Avionics Subsystems, Point-of-Sale (POS) Terminals, Embedded Networking Equipment (Routers / Bridges), Medical Instrumentation (Long-Life-Cycle).

🏭

Industrial Automation Controllers

The MC68340FE16VE's 32-bit CPU32 core with integrated timer modules, dual-channel DMA, and serial communications interface makes it a self-contained controller for legacy PLC-style industrial-automation backplanes. Its 3.3V supply matches modern industrial-rail designs while the CPU32 instruction set preserves firmware portability from earlier 68k-based controllers. Typical in this role: the device runs background DMA-driven sensor scans while the CPU executes ladder-logic-equivalent control loops. Compared to a discrete CPU + external DMA design, the MC68340FE16VE replaces three ICs with one, reducing board area and BOM cost in industrial-control products with 10+ year lifecycles.

🌐

Telecom Base Station Control Plane

The MC68340FE16VE was widely adopted in telecom equipment for control-plane processing (call setup, signalling, alarms) rather than user-plane DSP workloads. The enhanced SCI with hardware baud-rate generator simplifies direct connection to telecom supervisory links, while the integrated parallel port and chip-select logic interface to companion framers and TDM chips. The 16.78 MHz clock provides sufficient throughput for control-plane tasks at sub-1 ms latency. In this role, the device typically sits alongside a separate DSP or ASIC for user-plane processing, with the MC68340 handling housekeeping and low-level protocol stacks via the M68000 instruction set.

✈️

Legacy Aerospace / Avionics Subsystems

The MC68340FE16VE in its ceramic CQFP package is qualified for many legacy aerospace programs that specified the M683xx family decades ago and cannot easily migrate to modern processors without re-qualification. The ceramic package offers hermeticity and reliability suitable for high-vibration, wide-temperature avionics environments, and the 68k instruction set allows reuse of DO-178B-validated software baselines. The 3.3V supply reduces power dissipation compared to 5V variants, important for thermal budgets in sealed aerospace enclosures. This is a 'fit-and-function' maintenance role rather than a new-design role.

🖥️

Point-of-Sale (POS) Terminals

The MC68340FE16VE's combination of a 32-bit CPU32 core, integrated DMA, and parallel port with chip-select logic made it a common choice for late-1990s POS terminals that required cryptographic acceleration offload to a coprocessor plus magnetic-stripe reader DMA. The 16.78 MHz clock and 32-bit ALU handle transaction encryption in software when no dedicated accelerator is present, and the integrated timers drive display refresh and key-scanning without external timer ICs. The 3.3V supply simplifies integration with modern POS peripherals that share the same rail. Many deployed POS terminals continue using this part for spare-parts replacement and 10-year support contracts.

🌐

Embedded Networking Equipment (Routers / Bridges)

The MC68340FE16VE is suited to mid-1990s/early-2000s bridge and router control planes where a CPU32 handles routing-table management, SNMP agent execution, and low-speed serial WAN link management. The enhanced SCI with hardware baud-rate generator directly drives RS-232/RS-485 console and management ports, while the parallel port glues to Ethernet MAC or framers via external chip-select lines. The 24-bit external address bus supports up to 16 MB of external DRAM and ROM, sufficient for embedded routing firmware of that era. Many such systems remain in service today.

💊

Medical Instrumentation (Long-Life-Cycle)

The MC68340FE16VE is specified in several long-life-cycle medical-instrumentation platforms (patient monitors, infusion controllers) where regulatory re-qualification costs make MPU changes prohibitively expensive. The integrated DMA and timers simplify deterministic data acquisition from analog front-ends, while the CPU32 executes validated measurement and control firmware written for the 68k toolchain. The ceramic CQFP package offers the reliability demanded by IEC 60601-1 medical safety standards. This is a continuing-aftermarket role rather than a new-design role.

What is the MC68340FE16VE and what core does it use?
The MC68340FE16VE is a 32-bit M683xx-family microprocessor from NXP featuring a CPU32 core that is M68000-compatible with table-lookup and low-power extensions. According to the manufacturer datasheet, the device integrates a CPU32, dual-channel DMA, two timer modules, an enhanced serial interface, and chip-select logic on a single die operating up to 16.78 MHz.
What is the maximum clock frequency of the MC68340FE16VE?
The MC68340FE16VE operates at a maximum clock frequency of 16.78 MHz, encoded by the '32' in 'FE16' inside the MPN. This places it in the lower-band of M683xx MPU performance, suitable for control-plane rather than compute-intensive workloads such as industrial automation.
What package does the MC68340FE16VE use?
The MC68340FE16VE comes in a 144-pin Ceramic Quad Flat Package (CQFP, also written 144-BCQFP) measuring 26.77 x 26.77 mm. This is a large surface-mount package with gull-wing leads, typical of late-1990s MPU designs, requiring substantial PCB land area and JEDEC-standard CQFP layout.
What supply voltage does the MC68340FE16VE require?
The MC68340FE16VE operates from a 3.3 V supply, the 'VE' suffix in the MPN denoting 3.3V operation as opposed to the 5V 'E' suffix. Older M68340 variants required 5V rails; modern designs using this part must provide a clean 3.3V source with adequate bulk decoupling.
Is the MC68340FE16VE RoHS compliant and lead-free?
Yes. According to NXP's product information, the MC68340FE16VE is RoHS compliant and lead-free, confirmed by multiple distributors including DigiKey and Heisener. This makes it suitable for integration into modern lead-free assembly lines despite being a legacy MPU design.
What is the operating temperature range of the MC68340FE16VE?
The MC68340FE16VE has a commercial operating temperature range of 0C to +70C, as indicated by the 'FE' temperature grade in the MPN suffix. For extended-temperature industrial or aerospace applications, the 'FE' variant should be replaced with a V (extended) or M (military) temperature grade part.
How much does the MC68340FE16VE cost and is it in stock?
The MC68340FE16VE lists at approximately $55.53 per unit at qty-1 as of 2026-10-16, with breaks reaching about $33.32 at qty-1000. Heisener reports 6,496 units in stock; XAIPART inventory should be confirmed before ordering as the part is approaching end-of-life.
Where can I buy the MC68340FE16VE online?
The MC68340FE16VE can be sourced from DigiKey Marketplace (Flip Electronics), Mouser, Heisener, Xecor, Nantian, and authorized distributors as of 2026-10-16. For OEM production volumes, requesting a direct quote from NXP or franchised distributors is recommended due to the part's legacy status.
What is the lead time for the MC68340FE16VE?
Heisener reports the MC68340FE16VE can ship immediately from stock, with estimated delivery between April 24 and April 29 if expedited shipping is chosen (as of 2026-10-16). Lead time may extend significantly if stock depletes, since the part is NXP NRND.
What is a drop-in replacement for the MC68340FE16VE?
The MC68340FE16AE is a drop-in replacement for the MC68340FE16VE, sharing the same 144-CQFP package and pinout but operating at 5V instead of 3.3V. For 3.3V operation with identical pinout, the MC68340FE16VE itself is the canonical choice; for modern designs a PowerPC or ColdFire MCU is recommended.
How does the MC68340FE16VE compare to a ColdFire or PowerPC MPU?
Compared to a modern ColdFire or PowerPC MPU, the MC68340FE16VE delivers far less compute performance (16.78 MHz CPU32 vs hundreds of MHz ColdFire V2/V4), consumes more power per instruction, and uses the legacy 144-CQFP footprint. However, it preserves 68k software portability, which is why it remains specified in long-life-cycle industrial and aerospace retrofits.
When should I choose the MC68340FE16VE over a modern microcontroller?
Choose the MC68340FE16VE when your application requires 68k binary portability, must drop into an existing 144-CQFP PCB layout, or is part of a long-life-cycle industrial/aerospace retrofit that forbids redesign. For new designs, a ColdFire MCF5225x or Kinetis K-series typically offers better performance per dollar and integrates peripherals the 3.34 lacks.
Is the MC68340FE16VE pin-compatible with the MC68340FE16AE?
The MC68340FE16VE (3.3V) and MC68340FE16AE (5V) share the same 144-CQFP pinout and are pin-compatible at the PCB level. However, they cannot be freely swapped in the same design because the supply rails differ; substituting one for the other requires verifying that downstream logic tolerates the voltage change.
Where can I download the MC68340FE16VE datasheet PDF?
The MC68340FE16VE datasheet is available on NXP's website at https://www.nxp.com/docs/en/data-sheet/MC68340.pdf, which contains the full electrical characteristics, AC timing, DMA descriptor format, and chip-select programming model. DigiKey and Mouser also host the datasheet on their product pages.
Where do I find the MC68340FE16VE pinout?
The MC68340FE16VE pinout for the 144-CQFP package is documented in section 9 (Pin Assignment) of the NXP MC68340 datasheet, listing pin numbers, signal names, and pin multiplexing for the bus, DMA, timers, SCI, and parallel port. The XAIPART product page also renders the same pinout in SVG form for direct reference.

선택 가이드

Choose the MC68340FE16VE when maintaining 68k firmware portability, fitting into an existing 144-CQFP PCB layout, or supporting long-life-cycle industrial/aerospace retrofits is critical. Choose the MC68340FE25VE (same package, 25 MHz) when you need 49% more throughput without redesigning the PCB. Choose the MC68340FE16VBE (burn-in screened) for reliability-critical avionics or medical programs. Choose the MC68340FE16AE only when the surrounding logic requires a 5V supply. For new designs not constrained by 68k legacy, evaluate the ColdFire MCF5225x family, which offers higher clock rates, lower power, and smaller QFP packages at comparable BOM cost. All five parts share the same 144-BCQFP footprint, enabling PCB reuse across frequency grades and temperature/voltage variants.

설계 노트

Provide a clean 3.3V rail with at least 200 mA of headroom for the MC68340FE16VE plus peripherals. The MPU's core logic and I/O buffers draw from the same VDD plane; place a 10 uF tantalum + 0.1 uF ceramic decoupling pair within 25 mm of each VDD pin. The 144-CQFP package spreads VDD/VSS around the perimeter to reduce inductance, so prefer multi-point power injection rather than single-feed wiring.

The MC68340FE16VE is specified for 0C to +70C operation; derate clock frequency by 1% per degree above 60C if operating in enclosed industrial cabinets. The ceramic CQFP package has a thermal resistance of approximately 25 C/W junction-to-ambient in still air; ensure at least 50 mm of copper heat-sink area beneath the package or attach a small clip-on heatsink if the enclosure exceeds 50C ambient. (Estimated thermal value based on typical 144-CQFP packaging.)

Use a 4-layer PCB with continuous ground and power planes to control the impedance of the 32-bit data bus and 24-bit address bus. Match trace lengths to within 25 mm across byte lanes to preserve bus timing margins; keep bus traces short (<150 mm) and avoid routing parallel to high-current switching signals. The 144-CQFP land pattern requires 0.64 mm pitch pads with 0.15 mm solder mask relief per JEDEC CQFP guidelines.

Do not confuse the FE16VE (3.3V) with FE16AE (5V) variants; substituting one for the other will damage downstream 3.3V peripherals. Ensure unused IRQ pins are tied high through 10 kohm pull-ups to avoid spurious interrupts during reset. The TEST pin (124) must be left floating or tied high in normal operation - pulling it low forces factory test mode and prevents normal boot. Always pull the RESET pin high with a 10 kohm pull-up to VDD for proper startup.

Series-terminate the address and data buses with 33 ohm resistors close to the MPU to damp ringing on the 144-CQFP's relatively long gull-wing leads. Place termination resistors within 25 mm of the MPU pins and isolate bus traces from clock and reset signals with at least 3x the trace-spacing distance. Use a 4-layer stackup with 0.2 mm dielectric and matched-impedance routing for bus signals operating above 8 MHz.
