MC68340CAB25E Ringkasan

The NXP (formerly Freescale) MC68340CAB25E is a high-performance 32-bit integrated microprocessor with direct memory access (DMA), combining an enhanced M68000-compatible CPU32 core, two independent 32-bit DMA channels, two timer modules, a serial communications interface, and a system integration block on a single die. The device operates at 25 MHz, delivers 32-bit CISC performance from a lower-cost 16-bit memory system, and is housed in a 144-pin Ceramic Quad Flat Pack (CQFP-144 / QFP-144 28x28 mm) package.

Background - What is a CPU32 microprocessor? A CPU32 is a 32-bit CISC (Complex Instruction Set Computer) microprocessor from the Freescale/NXP M68000 lineage, the direct architectural successor to the original MC68000. It executes the M68K instruction set in 32-bit form while remaining object-code compatible with older 68000/68010/68020 software. CPU32 parts such as the MC68340 family integrate not only the processor core but also system peripherals (DMA, timers, serial, chip-select logic), reducing the part count for embedded industrial designs. The MC68340 sits inside the broader hierarchy MPU -> microprocessor -> 32-bit embedded controller -> industrial computing subsystem.

Key features include the CPU32 core, two 32-bit DMA channels, dual 16-bit general-purpose timers (T1/T2), a serial communication port (SCP), a serial peripheral interface (QSPI in some mask sets), eight chip-select outputs with wait-state logic, a 16-bit data bus mode for memory-cost optimization, and a fully static CMOS design that supports DC-to-25 MHz operation. The bus is multiplexed, and the part supports DRAM refresh via internal controllers.

Typical applications are industrial control, telecommunications line cards, factory automation, medical instrumentation, point-of-sale terminals, military/aerospace systems, and legacy embedded designs that require deterministic 68K software compatibility. The 144-CQFP package is well-suited to through-hole or socketed industrial assemblies and is rated over the standard -40C to +85C industrial temperature range.

When designing with the MC68340, ensure the external bus is properly terminated, the DRAM controller is initialized before bus cycles begin, and the reset configuration mode pins are pulled to the correct levels during power-up. Designers migrating new designs away from this family should consider ColdFire MC68SECC608 or modern ARM Cortex-M parts - per NXP community guidance, no pin-to-pin drop-in replacement exists.

Aplikasi Umum

MC68340CAB25E cocok untuk 6 aplikasis: Industrial Process Control, Telecommunications Line Cards, Medical Instrumentation, Point-of-Sale Terminals, Legacy Aerospace / Military Avionics, Embedded Data Acquisition Systems.

🏭

Industrial Process Control

The MC68340CAB25E fits industrial process control because its CPU32 core delivers deterministic 32-bit CISC performance at 25 MHz with object-code compatibility with the legacy 68000/68010/68020 instruction set, allowing reuse of proven control firmware without recompilation. The two integrated 32-bit DMA channels offload high-throughput data moves (sensor acquisition, actuator pulse trains) from the CPU, and the dual 16-bit timers (T1/T2) handle encoder/PWM/precision-event timing typical of PID loops. The 144-CQFP ceramic package and -40C to +85C industrial temperature grade suit factory-floor cabinets. Compared to a modern Cortex-M3, the 68340 trades raw MHz for software legacy, but its deterministic DMA make it suitable for legacy PLCs and motor controllers that already run M68K assembly.

Telecommunications Line Cards

Although the MC68340CAB25E lacks the QUICC RISC communications processor of the MC68360, its integrated serial communication port (SCP) and QSPI handle low-density telecom line-card traffic such as D-channel signaling, control-plane messaging, and configuration EEPROM access. The 25 MHz CPU32 core can sustain light-weight protocol stacks (X.25, LAPD, simple HDLC control). For higher channel densities, designers pair the MC68340 with an external HDLC controller. The CQFP-144 package suits through-hole backplane assemblies historically used in telecom shelves. This is a cost-down approach when the application does not require the full QUICC multi-channel SCC capability.

Medical Instrumentation

The MC68340CAB25E serves medical instrumentation with its deterministic DMA, predictable interrupt latency, and the long-term reliability of the M68K instruction set used in FDA-cleared legacy devices. The CPU32 core's M68000 compatibility allows reuse of validated diagnostic code, while the dual timers and chip-select logic simplify interfacing to analog front ends, LCD/keypad controllers, and patient-monitoring peripherals. The ceramic CQFP-144 package offers hermeticity suitable for medical-imaging and patient-monitoring enclosures. Designers building new medical designs should weigh this part's obsolete/EOL status against modernization, but for installed-base support and field replacement, the 68340 is a known-quantity solution.

💳

Point-of-Sale Terminals

The MC68340CAB25E is well-suited to legacy point-of-sale (POS) terminals because its 32-bit CPU32 core, 8 programmable chip-select outputs, and DRAM controller let it interface directly to flash, SRAM, character LCD, keypad matrix, magnetic-stripe reader, and serial peripherals without external glue logic. The dual DMA channels can sustain printer bursts and cash-drawer pulse streams, and the QSPI/SCP handle secure PIN-pad or EFT-POS serial links. The 144-CQFP package fits the through-hole mainboards typical of legacy countertop terminals. Engineers maintaining installed POS fleets rely on the 68340's known firmware, but new POS designs should evaluate ARM Cortex-A or Cortex-M parts for cost and power reasons.

Legacy Aerospace / Military Avionics

The MC68340CAB25E, especially the 'A' or 'M' temperature-grade variants, has been used in military/aerospace avionics where its object-code compatibility with the Motorola 68000 family, deterministic DMA, and hermetic CQFP-144 ceramic package meet ruggedization and obsolescence-management requirements. Its extended temperature range and proven reliability make it acceptable for line-replaceable units (LRUs) where re-engineering a flight-certified board is prohibitive. For new avionics, NXP and NXP community guidance advise modern ColdFire or ARM Cortex-R parts, but legacy LRUs continue to depend on 68K CPU32 stock. The 'E' industrial variant (this part) is the commercial-off-the-shelf (COTS) baseline; 'A' and 'M' grades extend temperature further.

🖥️

Embedded Data Acquisition Systems

The MC68340CAB25E handles embedded data-acquisition systems because the CPU32 core drives fast ADC/DAC sampling while the two 32-bit DMA channels transfer samples to memory without CPU overhead, achieving sustained throughput at 25 MHz. The dual 16-bit timers provide accurate sample-rate generation, and the eight programmable chip-select outputs simplify interfacing to SRAM, flash, FIFOs, and external ADC converters. The QSPI/SCP ports link to external sensors or front-panel controllers. Designers building new high-channel-count DAQ should consider modern ARM Cortex-M4 with DMA + 12-/16-bit ADC, but the 68340 remains a viable platform for maintaining installed seismic, vibration, or rotating-machinery monitoring systems.

What is the MC68340CAB25E?
The MC68340CAB25E is a 32-bit integrated microprocessor from NXP/Freescale, part of the M683xx family, integrating a CPU32 (M68000-compatible) core, two 32-bit DMA channels, two 16-bit timers, a serial communications port (SCP), and a system integration block on one die. According to the NXP datasheet MC68340, it operates at 25 MHz and is packaged in a 144-pin CQFP. It delivers 32-bit CISC performance from a 16-bit memory system for cost-sensitive embedded designs.
What is the clock speed of the MC68340CAB25E?
The MC68340CAB25E runs at 25 MHz. The '25' designator in the part number specifies the maximum CPU clock frequency, while the 'E' suffix indicates an industrial/extended temperature grade. According to the Freescale/NXP product page, the device is fully static CMOS, allowing operation down to DC for low-power standby. For higher performance within the same family, the 16 MHz MC68340CAB16E and 20 MHz MC68340CAB20E variants also exist.
What package does the MC68340CAB25E use?
The MC68340CAB25E is housed in a 144-pin Ceramic Quad Flat Pack (CQFP-144), measuring 28 mm x 28 mm with a 0.64 mm pitch. The 'CAB' portion of the part number specifies this ceramic QFP package, per Freescale/NXP datasheet conventions. Designers should note that the CQFP-144 is a through-hole-compatible ceramic package, distinct from the plastic QFP-144 found on later mask sets. No pin-to-pin drop-in replacement exists for this package footprint.
Is the MC68340CAB25E still in production?
No. The MC68340CAB25E is listed as obsolete/End of Life on the NXP product page. The product change notification archive and NXP community confirm that no direct pin-to-pin replacement is offered and the 68K CPU32 family is not recommended for new designs. Buyers currently rely on authorized distributors (Rochester Electronics, NXP franchised stockists, and brokers) for last-time-buy and obsolete-stock inventory. Designers should evaluate ColdFire MC68SECC608 or modern ARM Cortex-M controllers for new projects.
Where can I buy the MC68340CAB25E today?
The MC68340CAB25E is available through authorized obsolete-stock specialists such as Rochester Electronics (per DigiKey listing), Win Source, Wolfchip, Xecor, and Avaq. Pricing as of 2026-10-16 ranges from approximately USD 19.85 at 1000-piece quantities to USD 38.50 at qty-1, reflecting its obsolete status. Lead times vary; Rochester Electronics, which DigiKey sources from, typically quotes immediate shipment for stock on hand. Always verify date code and traceability for legacy parts.
What is the lead time and stock status of the MC68340CAB25E?
Lead time for the MC68340CAB25E depends on distributor inventory; some brokers (Wolfchip) reported 35,545 units in stock as of 2026-05-27, while franchised distributors like DigiKey source through Rochester Electronics with immediate shipment on available stock. Because the part is obsolete/EOL, lead time on large qty-1000+ orders may extend 8-16 weeks if the broker does not hold that volume. Always request a quote for qty >500 to confirm current stock.
What is the price of the MC68340CAB25E?
The MC68340CAB25E unit price as of 2026-10-16 ranges from approximately USD 19.85 at 1000-piece quantities to USD 38.50 at qty-1, based on franchised and broker listings. Higher quantity tiers (5000+) are typically quoted on request because the part is obsolete. Pricing reflects remaining inventory rather than market production. Customers should obtain firm quotes for their required volume, as the 68K CPU32 market is thin and prices fluctuate with available stock.
What is a drop-in replacement for the MC68340CAB25E?
Per NXP community guidance (community.nxp.com/t5/ColdFire-68K-Microcontrollers), no direct pin-to-pin compatible drop-in replacement exists for the MC68340 family. The MC68340's 144-CQFP pinout is unique to that part. Modern migration paths include the ColdFire MCF68SECC608 (different package) and ARM Cortex-M controllers, both requiring PCB redesign and firmware rework. For pure software-compatible upgrades within the 68K family, the MC68360 (QUICC) is functionally similar yet uses QFP-240, not drop-in. Engineers should plan for redesign rather than seeking a drop-in.
MC68340CAB25E vs MC68302FC25C - what is the difference?
The MC68340CAB25E and MC68302FC25C are both 25 MHz 68K-family NXP/Freescale microprocessors, but they are not drop-in compatible. Per Xecor's parametric comparison, the MC68340 uses a CQFP-144 package and is a CPU32-based DMA+timer+SCP MPU, whereas the MC68302FC25C is packaged in PQFP-132 and integrates a 68K core with a built-in communication processor (serial-comm controller, RISC comm engine) for telecom line cards. The MC68340CAB25E targets general industrial use; the MC68302 targets communication/serial aggregation.
MC68340CAB25E vs MC68360AI25L - which should I choose?
The MC68340CAB25E is a CQFP-144 industrial MPU with CPU32 + DMA + timers, while the MC68360AI25L is a 25 MHz QUICC (QFP-240) that bundles a CPU32 core with a RISC communications processor, four SCCs, two SMCs, SPI, and a 16-channel DMA. Choose MC68340CAB25E for cost-sensitive industrial control where on-chip serial/serial-port needs are modest. Choose MC68360AI25L for telecom line cards or any application needing multiple HDLC/transparent serial channels. They are not pin-compatible; the MC68340 has 144 pins and the 360 has 240.
When should I choose MC68340CAB25E over a modern ARM Cortex-M part?
Choose MC68340CAB25E only when maintaining legacy 68K software compatibility, when the existing 144-CQFP PCB cannot be respun, or when an installed base demands field-replacement of EOLed stock. For new designs, an ARM Cortex-M3/M4 (e.g., NXP LPC1768 at 100 MHz, STM32F4 at 168 MHz) provides higher performance, lower power, modern toolchains, and active lifecycle support at lower cost. NXP explicitly recommends ColdFire MCF68SECC608 or modern ARM MCUs for new designs because 68K CPU32 is end-of-life.
Where can I download the MC68340CAB25E datasheet PDF?
The official NXP MC68340 datasheet PDF is available at nxp.com/docs/en/data-sheet/MC68340.pdf (referenced in NXP's product page).

Be aware that Freescale datasheet rev numbers may differ from NXP reissues, but pinout and electrical specs remain consistent.

The MC68340CAB25E has a 144-pin CQFP pinout that includes the multiplexed 32/16-bit data bus (D0-D31), 24-bit address bus (A0-A23), chip-select outputs (CS0-CS7), DMA request/acknowledge pairs (DREQ0/DACK0, DREQ1/DACK1), timer I/O (TIN1/TOUT1, TIN2/TOUT2), serial port signals (SCP TX/RX, QSPI SCK/CLK/MOSI/MISO/PCS), mode/configuration pins (MD0-MD3, HALT, RESET), and supply/ground pins. Refer to the NXP datasheet pinout section for the exact assignment, as 144-CQFP pinouts cannot be inferred without the official source.
Is the MC68340CAB25E RoHS compliant?
RoHS compliance status for the MC68340CAB25E is not explicitly stated in the verified web data available. The part is packaged in a ceramic QFP with a Freescale-era date, so it is likely non-RoHS (lead-bearing ceramic package), but this is not authoritative. Customers requiring RoHS-compliant builds should request a certificate of compliance from the distributor and consider a plastic QFP variant if offered. If RoHS is critical, the obsolescence status of the part makes compliance documentation difficult to obtain.
What is the operating temperature range of the MC68340CAB25E?
The 'E' suffix in MC68340CAB25E indicates the extended/industrial temperature grade, typically -40C to +85C ambient. This is consistent with the Freescale/NXP 68K CPU32 family industrial specification. For a wider -55C to +125C military/aerospace grade, the 'A' or 'M' suffix variants (e.g., MC68340CAB25A) are available. Always confirm the exact limits in the official NXP datasheet MC68340 because process mask revisions may shift the limits slightly. The CQFP-144 package is rated for the same industrial envelope.

Panduan Pemilihan

Choose the MC68340CAB25E when you need a 25 MHz CPU32 industrial MPU in a hermetic 144-CQFP package and your design must remain on legacy 68K firmware - particularly in factory-floor PLCs, medical-instrumentation line-replaceable units, or telecom line cards with modest serial-channel needs. Choose the MC68340CAB20E for a drop-in with 20% lower clock speed when power dissipation is a concern, or the MC68340CAB16E for 16 MHz cost-down or thermal-constrained variants (note 36% clock reduction is near the drop-in floor). Choose the MC68340AB25E plastic QFP-144 if you need the same 25 MHz performance in a non-hermetic industrial assembly. For new designs, NXP explicitly recommends migrating to ColdFire or ARM Cortex-M parts because no drop-in pin-compatible replacement exists for this family - plan for PCB redesign if migrating to modern silicon.

  • Ceramic CQFP-144 hermetic package for rugged/military-grade applications (vsMC68340AB25E)
  • Higher-density integration (CPU32 + DMA + 2 timers + 8 chip-selects + DRAM controller) than MC68302 (vsMC68302FC25C)

Catatan Desain

Do not assume a pin-to-pin drop-in upgrade path exists for the MC68340 family. Per NXP community (community.nxp.com), no direct drop-in replacement is offered; ColdFire MC68SECC608 and modern ARM Cortex-M parts require PCB redesign and firmware rework. For obsolete-part maintenance, qualify a second source through Rochester Electronics or franchised brokers with date-code traceability, and consider stockpiling to bridge obsolescence gaps. Estimated: bus timing and wait-state register defaults must be initialized during reset configuration or the system will hang at first DRAM access.

The 144-CQFP ceramic package is a surface-mount component with a gull-lead profile - it can also be socketed (e.g., through-hole PGA-style sockets) for prototyping and field replacement. Ensure the PCB land pattern uses 0.64 mm pitch with the ceramic-pad thermal-relief rules for reflow or wave soldering. The package is large (28 mm body), so place decoupling capacitors (100 nF + 10 uF bulk) within 5 mm of each Vcc/Vss pair. Per the Freescale/NXP datasheet, the multiplexed address/data bus requires external latch devices (e.g., 74HC573) when interfacing to 8/16-bit peripherals.

At 25 MHz with a multiplexed 32-bit bus, signal integrity demands controlled-impedance routing (typically 50 ohm microstrip) for the address/data bus and critical control signals (/AS, /DS, /CS, R/W). Estimated: edge rates of 2-3 ns at 25 MHz on the CQFP-144 leads (typical 5 pF pin capacitance + ~30 pF trace) call for series-damping resistors (22-33 ohm) on heavily-loaded lines. Bus termination at the memory side with parallel-diodes or 33 ohm series resistors is recommended for backplane or long-trace designs.

The MC68340CAB25E operates from a single 5 V supply (typical M68K CPU32 specification); supply tolerance and current draw are not in the verified web data. Estimated: based on similar CPU32 masks, supply current is approximately 150-250 mA at 25 MHz. Use a linear regulator (e.g., 7805 or low-dropout) for clean power, and bulk-decouple Vcc/Vss pairs with at least one 10 uF tantalum + one 100 nF ceramic per two Vcc pins. Keep the reset and HALT pins pulled high via 10 kOhm resistors and driven low only by supervisory circuitry.
