MC68MH360EM33L - 33MHz CPU32+ MPU, 240-FQFP | NXP
MPN: MC68MH360EM33L ✗ סוף ייצורMC68MH360EM33L סקירה
A microprocessor (MPU) is an integrated circuit that contains the arithmetic logic unit (ALU), control unit, register set, and memory interface logic of a computer system on a single silicon die. In the system hierarchy, an MPU sits above microcontrollers (which add on-chip peripherals and memory) and below application processors (which add multimedia, security, and high-bandwidth interfaces). The M683xx QUICC family is positioned as a communications-optimized MPU, integrating dedicated serial and protocol engines to off-load the CPU32+ core.
Key features include a 32-bit CPU32+ instruction set with enhanced addressing modes, integrated communications peripherals (2 SCC, 2 SMC, 1 SPI), 4-channel DMA controller, DRAM controller with page mode support, and on-chip timers. The 33 MHz core delivers approximately 16 MIPS peak throughput while supporting M68000-family source compatibility for legacy code reuse. The 'L' suffix denotes a low-power process variant for reduced quiescent dissipation.
Typical applications include ISDN terminal adapters, router control planes, industrial serial-to-Ethernet bridges, and legacy M68K embedded control designs. The combination of an integrated communications processor and 32-bit core makes the MC68MH360EM33L particularly well-suited to multi-protocol telecom infrastructure where deterministic serial performance is required alongside general-purpose processing.
When designing with this device, validate supply-rail decoupling on all 5V-tolerant I/O banks and verify timing margins against the worst-case 33 MHz bus loading. Engineers migrating designs from earlier MH360 derivatives should review the silicon revision differences documented in the manufacturer datasheet errata.

יישומים טיפוסיים
MC68MH360EM33L מתאים עבור 6 יישוםs: ISDN Terminal Adapter, Industrial Router Control Plane, Legacy M68K Industrial Control, Telecom Multi-Protocol Bridge, Embedded Serial Concentrator, Legacy Telecom Base Station Controller.
ISDN Terminal Adapter
The MC68MH360EM33L's integrated QUICC communications processor with 2 SCC channels running HDLC and the 33 MHz CPU32+ core make it well-suited to ISDN terminal adapters that require simultaneous B-channel protocol handling and user-plane processing. The CPU32+ executes signaling stack and call-control code while the SCC off-loads the Layer-2 HDLC framing. Placed as the main MPU on the adapter board, the MC68MH360EM33L drives the external MC68160A Ethernet transceiver and ISDN U-interface codec; the 5V-tolerant bus interfaces directly to standard telecom glue logic. Its 32-bit datapath eliminates the bottlenecks seen with 8/16-bit microcontrollers in dual-channel ISDN applications.
מומלץ
Industrial Router Control Plane
In embedded router and gateway designs, the MC68MH360EM33L serves as the control-plane MPU managing routing tables, SNMP agents, and serial management interfaces. The 33 MHz CPU32+ provides sufficient throughput for low-to-mid packet rates, while the integrated 2 SCC ports handle HDLC-framed WAN links. Compared with 68k microcontrollers lacking integrated SCC, this device reduces BOM and PCB area. The QUICC peripheral set enables deterministic serial latency required by industrial control protocols, and the 240-FQFP footprint supports thermal headroom for the sustained processing loads typical of always-on industrial gateways.
מומלץ
Legacy M68K Industrial Control
For factories running long-lifecycle M68K firmware on assembly lines, the MC68MH360EM33L provides a pin-compatible refresh of the original MH360 silicon with the same CPU32+ ISA, allowing direct binary reuse. The QUICC communications engine and 4-channel DMA controller handle deterministic serial I/O for PLC backplanes, while the 32-bit datapath executes ladder-logic-to-CPU translation without breaking legacy timing budgets. The 'L' low-power suffix limits quiescent dissipation in always-on control cabinets, and the 240-FQFP package matches the original M68K board layout, eliminating costly mechanical retooling during control-system refresh projects.
מומלץ
Telecom Multi-Protocol Bridge
Multi-protocol telecom bridges that translate between HDLC, UART, and transparent serial streams benefit from the MC68MH360EM33L's 2 SCC plus 2 SMC combination, which simultaneously handles up to four independent serial channels. The CPU32+ runs protocol conversion while the QUICC engine executes DMA-driven framing. The 33 MHz speed grade delivers sufficient headroom for encryption overhead and statistical multiplexing; the integrated DRAM controller with page-mode support reduces external memory cost. The 240-FQFP package supplies the pin count needed for four serial ports plus parallel bus expansion to glue logic.
מומלץ
Embedded Serial Concentrator
The MC68MH360EM33L's 2 SCC plus 2 SMC enables an embedded serial concentrator that aggregates multiple HDLC or UART data streams into a single higher-speed uplink. Each SCC can be configured independently, with the QUICC DMA engine moving data between channels and main memory without CPU32+ intervention. At 33 MHz, the core executes channel arbitration, statistical multiplexing, and link-layer management. The wide 32-bit external data bus interfaces to fast SRAM/DRAM supporting aggregate throughput well above any single serial channel, and the 240-FQFP package provides ample I/O for status LEDs and configuration switches.
מומלץ
Legacy Telecom Base Station Controller
Base station controllers in legacy GSM/CDMA networks require deterministic serial performance for the Abis interface and backhaul links. The MC68MH360EM33L's QUICC communications processor with 2 SCC channels and 33 MHz CPU32+ core supplies the deterministic Layer-2 framing and the call-processing throughput typical of small-cell or picocell base station controllers. The integrated DRAM controller supports the working-set memory of a base station controller handling hundreds of subscribers, and the 240-FQFP package supplies the I/O count needed for backhaul, timing, and alarm interfaces. NXP's long-term support of the M683xx family has made this part a mainstay in installed telecom infrastructure.

הערות תכנון
The 240-FQFP MC68MH360EM33L draws core and I/O current on multiple VDD/VSS pin pairs distributed across the package. Use a star-ground topology with 0.1uF ceramic decoupling capacitors placed within 5 mm of each VDD pin, plus bulk tantalum or polymer capacitors (10-47uF) on the main 5V rail. The 'L' suffix reduces quiescent current relative to the standard part, but switching current at 33 MHz still requires robust bulk decoupling for the address/data bus transitions.
Route the 32-bit external data bus with matched trace lengths (delta < 1 cm) and a 50-ohm characteristic impedance to the SRAM/DRAM bank. Place the DRAM array as close as possible to the RAS/CAS outputs to minimize stub lengths. Keep the EXTAL/XTAL crystal traces short and shield them from address bus activity to avoid jitter injection into the system clock.
Do not assume the MC68MH360EM33L is fully software-compatible with newer PowerQUICC parts - the QUICC CPM register map is similar but interrupt vectors and command register layouts differ. Validate legacy M68K firmware against the M683xx programmer's reference manual before porting. Also, the part is NRND, so procurement should plan a second-source qualification in parallel with production deployment.
מידע על תאימות
RoHS compliance not confirmed in verified data. The 240-FQFP package historically used lead-containing finishes; engineers requiring RoHS assembly should request the LF suffix variant. AEC-Q100 is not applicable - this is a 5V telecom MPU, not an automotive-grade device.
