MC68EC060RC50 概要
What is a 32-bit embedded microprocessor? A 32-bit microprocessor is an integrated CPU core that processes 32-bit data words, instructions, and addresses in a single operation. The MC68EC060 belongs to the CISC (Complex Instruction Set Computer) M68000 lineage (microprocessor -> 32-bit MPU -> CISC -> M68k family -> M68060 generation), with hypernyms including CPU, MPU, processor IC, and embedded processing unit. The 'EC' suffix denotes the Embedded Cache variant, where both I-cache and D-cache are integrated on-die. The part targets designers maintaining legacy VMEbus, Amiga, Atari, or industrial M68k control systems that prefer backward binary compatibility over migration to ColdFire or ARM.
Key features of the MC68EC060RC50 include its MMU with 4-entry fully associative instruction and data translation lookaside buffers (ITLB/DTLB) supporting 4KB to 8MB pages, a branch cache combining buffer (CB), and a barrel shifter for single-cycle shifts. The device implements the M680x0 instruction set fully, supporting BERR/BR/ACK arbitration, bus snooping for SMP, and an interrupt controller. Its on-die FPU runs double-precision operations at sub-microsecond latency and includes an operand pipelining mechanism typical of the 68060 family.
Typical applications include VMEbus single-board computers (SBCs), industrial automation controllers, military/aerospace avionics, Amiga/Atari-compatible accelerator boards, and telecom base stations built around legacy M68k firmware. At 50 MHz it executes Dhrystone 1.1 at approximately 60 MIPS. Designers must implement a bus arbiter, reset controller, and clock source (50 MHz fundamental or 2x with internal PLL); the 'EC' lacks the PMMU unit found on the full MC68060, so systems requiring virtual memory must use the MC68060RC50 or add a discrete MMU. Lead-free / RoHS status: per distributor data this BEPGA variant contains lead, so it is RoHS non-compliant by default.
When designing with this part, treat thermal management as the primary constraint: the 206-pin BEPGA dissipates up to 7 W at full load with no integrated heatsink, so a heatsink and forced-air cooling are mandatory in enclosed chassis. The 5 V tolerant I/O simplifies legacy peripheral glue logic, but 5 V inputs on 3.3 V rails must be current-limited. Cache coherency for multi-master designs requires bus snooping enabled via the SNOOP pin and proper BR/BG arbitration.

主な用途
MC68EC060RC50 の用途: 6 件s: VMEbus Industrial SBC, Amiga/Atari-class Accelerator Boards, Military and Aerospace Avionics, Telecom Base Station Controllers, Medical Imaging Front-End Controllers, Printer and Imaging Engine Controllers.
VMEbus Industrial SBC
The MC68EC060RC50 serves as the host CPU on legacy VMEbus single-board computers used in factory automation and defense C4I systems where M68k firmware is mature and certified. Its 50 MHz execution rate (approximately 60 MIPS Dhrystone 1.1) and integrated 8KB+8KB caches provide adequate headroom for process-control loops while preserving binary compatibility with installed SCADA code. The integrated IEEE-754 FPU accelerates inverse-kinematics and PID calculations in robotic controllers without requiring an external coprocessor. Unlike the full MC68060RC50, the omitted PMMU simplifies the VME memory map when running flat-model real-time kernels (RTEMS, OS-9, VxWorks AE). Designers should pair the EC060 with a discrete bus arbiter and 50 MHz synchronous SRAM with a 20 ns tCO budget.
おすすめ
Amiga/Atari-class Accelerator Boards
Retro-computing enthusiasts use the MC68EC060RC50 as an upgrade processor on Amiga 4000 and Atari Falcon/CT63 accelerator cards, replacing the stock 68040 in a PGA socket. The 50 MHz clock yields a 4-5x speedup in Dhrystone benchmarks over a 25 MHz 68040 while preserving AmigaOS / TOS / MiNT binary compatibility. Its on-die caches reduce CPU-to-RAM bottleneck cost relative to 68040 with off-chip cache, important for tile-based blitter workloads. The 5 V tolerant I/O and 206-pin BEPGA package retain mechanical compatibility with aftermarket tower coolers designed for the 68040 form factor. Designers of such accelerators must retain a discrete bus arbiter (e.g., 74LS245-style) because the EC060 lacks the 68040-era BG/BR handshake logic at higher speeds.
おすすめ
Military and Aerospace Avionics
The MC68EC060RC50's wide -40C to +85C industrial temperature screening and BEPGA hermetic ceramic package suit avionics and MIL-STD-1553 databus systems running classified M68k firmware. At 50 MHz it executes navigation routines and Kalman-filter floating-point math within the latency windows required for tactical-grade IMU processing. The lack of PMMU on the EC060 variant avoids virtual-memory thrash under vibration-induced memory faults, an important consideration for DO-178C design assurance. Its 5 V tolerant I/O allows direct connection to legacy ARINC-429 transceivers and MIL-1553 Manchester II codecs without level shifters. Long-life support for this part is available via Rochester Electronics' franchised military legacy product line.
おすすめ
Telecom Base Station Controllers
Cellular base-station baseband controllers in 2G/3G legacy networks (GSM, TDMA, early UMTS) used the MC68EC060RC50 as the Layer-2 protocol engine because its on-die FPU handles Viterbi soft-decision decoding efficiently while the integrated caches shelter the L1 datapath from GMSK burst pipeline stalls. The 50 MHz clock offers enough processing margin for 4-channel TRX baseband while keeping dissipation under 6 W in a sealed outdoor enclosure. Its 5 V tolerant I/O connects directly to legacy E1/T1 framers and HDLC controllers used in BSC cabinets. Although newer base stations have migrated to PowerQUICC and QorIQ, North American brownfield sites still deploy EC060 designs in live networks.
おすすめ
Medical Imaging Front-End Controllers
MRI and CT scanner front-end controllers (gradient drivers and RF receiver boards) deploy the MC68EC060RC50 for deterministic, low-jitter task dispatching where predictable interrupt latency is more critical than peak throughput. Its 5 V tolerant I/O interfaces directly to legacy ultrasound transmitter ASICs and high-voltage gradient amplifier control ADCs from the 1990s/2000s installation base. The on-die FPU accelerates the discrete Fourier transforms used in beam-forming arrays without an external math coprocessor. Embedded Cache (EC) eliminates the PMMU's TLB-miss variance, helping deterministic real-time guarantees required for IEC 60601-1 medical safety standards. Long-term service programs through NXP authorized distributors keep these medical devices in service for decades.
おすすめ
Printer and Imaging Engine Controllers
High-end monochrome and color laser printers of the late-1990s/early-2000s deployed the MC68EC060RC50 as the page-description-language (PDL) interpreter, parsing PostScript Level 2, PCL 6, and proprietary JBIG streams at engine speeds above 60 pages per minute. Its 50 MHz clock and dual-issue integer pipeline rasterize 1200-dpi halftones in real time while running the user interface panel controller. The integrated FPU accelerates 2D coordinate transforms in Adobe-recommended PostScript rendering without an external coprocessor. The EC060's flat-memory model is sufficient since most embedded printer firmware is compiled to physical RAM only. Field-upgrade to the 75 MHz variant inside the same BEPGA socket noticeably improves first-page-out time on heavy color jobs.

設計ノート
Estimated: at 50 MHz full-load with all four functional units active, core power is approximately 5.5 W (3.3 V x ~1.7 A). With theta_JA of ~8 C/W for the BEPGA-206 package and a 25 C ambient, Tj rises ~44 C above ambient to ~69 C - within the 110 C Tj max, but leaves only ~41 C margin for altitude/altitude-derating. Mount a 25 C/W extruded aluminum heatsink with thermal interface material and add 100 LFM forced airflow inside enclosed chassis. If upgrading to the 75 MHz drop-in (RC75), dissipation rises to ~8 W so a 15 C/W heatsink or 200 LFM airflow is required.
The 206-pin BEPGA uses a 0.10 inch pin pitch through-hole footprint that matches the MC68040 PGA layout exactly, enabling drop-in socket reuse. Place 0.1 uF X7R ceramic decoupling caps within 5 mm of each VCC pin (G9/G11) and one 10 uF tantalum per VCC pair. Run the 50 MHz clock trace as a 50 ohm microstrip with series damping at the source, keep the CLK trace shorter than 25 mm, and shield it with GND on both sides. The RESET, IPL[2:0], BERR, and BR lines must be pulled high with 4.7 kohm external resistors because the EC060's internal pullups are too weak for noisy industrial environments.
First: do not assume the EC060 has a PMMU - it does NOT, so do not include MMU tables in your linker script and bypass any early Linux/m68k boot code that expects 68060 PMMU registers (TT0/TT1 transparently return 0 on EC060). Second: the EC060's CDIS pin disables BOTH caches simultaneously when driven low; tying it high through a 4.7 kohm pullup is mandatory at board reset. Third: do not exceed the absolute maximum VCC of 3.6 V - the EC060 has no internal 5 V regulator, unlike the original 68040. Finally, before migration from 68040 code, audit instructions that touch pmmu tables, line-fill buffers, or branch cache flush registers, since EC060 behavior differs in these areas.
The EC060's 32-bit address and data buses operate at 50 MHz (20 ns period) with 5 V swing and edge rates of 0.5 - 1.0 ns. To meet FCC/CE radiated emissions on industrial enclosures, series-terminate the address, data, AS, DS, and R/W lines with 33 ohm resistors at the driver pins. Use a four-layer PCB with continuous GND planes under the BEPGA footprint to provide a return-current reference for the 32-bit bus; vias through power planes should be staggered, not stacked. Maintain a 50 ohm impedance on the bus and clock traces, and verify with TDR that stubs from the PGA socket are < 10 mm. Avoid 90-degree bends on all 32-bit bus traces - use 45-degree or curved traces exclusively.
