MC68EN360ZQ33L - 33MHz QUICC Ethernet MPU | NXP | BGA-357
MPN: MC68EN360ZQ33L ✗ Cuối đờiMC68EN360ZQ33L Tóm tắt
A microprocessor (MPU) in the M683xx family is a 32-bit CISC/RISC processor originally derived from the Motorola 68000 lineage, designed for embedded networking, telecom, and industrial control workloads. It belongs to the broader category of microprocessors -> embedded processors -> communication controllers, sitting hierarchically below application processors and above simple microcontrollers in capability and integration. The "EN" in MC68EN360 denotes the integrated Ethernet MAC, while "ZQ33L" encodes the 357-BGA package, 33 MHz clock, and low-voltage/legacy process variant.
Key features include a 33 MHz CPU32+ core with hardware multiply/divide, an integrated 10/100 Ethernet MAC (Fast Ethernet controller), four Serial Communication Controllers (SCCs) supporting HDLC/SDLC, UART, transparent modes, BISYNC, and Ethernet, plus two Serial Management Controllers (SMCs), a Serial Peripheral Interface (SPI), an I2C bus interface, a DRAM controller supporting up to 32 address bits, a 16-channel DMA, timers, and a parallel I/O port. The device operates from a single 5V supply and is housed in a 357-ball Plastic BGA (25 x 25 mm).
The QUICC engine architecture offloads communication processing from the CPU32+ core, allowing line-rate handling of multiple serial protocols concurrently. With 4K+4K on-chip caches, MMU, and burst-mode memory support, it can sustain deterministic throughput for routing, bridging, and protocol-conversion tasks typical of legacy telecom and industrial routers, bridges, and embedded networking appliances.
Typical applications include legacy routers and bridges, industrial Ethernet gateways, telecom protocol converters, WAN access concentrators, serial-to-Ethernet device servers, and point-of-sale terminals. The integrated Ethernet MAC and multi-protocol SCCs make it well-suited to systems requiring concurrent Ethernet and legacy serial traffic handling.
When designing with this part, use Rochester Electronics or NXP/Freescale franchised stock because the part is mature and production is limited; verify thermal management for the 357-BGA, ensure the 5V supply is well-decoupled, and confirm the firmware toolchain (CPU32+/68K GCC or Diab) supports your protocol stack. The part is RoHS non-compliant and contains lead, so conformal coating or lead-free revalidation is required for new RoHS-mandated designs.

Ứng dụng tiêu biểu
MC68EN360ZQ33L phù hợp cho 6 Áp dụngs: Legacy Industrial Routers and Bridges, Telecom Protocol Converters, Serial-to-Ethernet Device Servers, Point-of-Sale (POS) Terminals, Industrial Ethernet Gateways, Embedded Networking Appliances.
Legacy Industrial Routers and Bridges
The MC68EN360ZQ33L is purpose-built for legacy industrial routers and bridges that require deterministic multi-protocol serial handling alongside integrated Ethernet. Its 33 MHz CPU32+ core, four SCCs supporting HDLC/SDLC/PPP/Frame Relay, and integrated 10/100 Ethernet MAC allow a single chip to terminate WAN links and bridge to LAN. The QUICC engine offloads protocol processing, freeing the CPU32+ for routing-table management, while the 4K+4K caches absorb routing-table lookups. Compared with discrete MPU+MAC designs, the integration reduces BOM cost and PCB area, ideal for legacy factory-floor routers that must remain in service for decades.

Telecom Protocol Converters
Telecom protocol converters that bridge E1/T1, V.35, RS-232, and Ethernet benefit from the MC68EN360ZQ33L's combination of SCCs, SMCs, and integrated Ethernet MAC. Each SCC can be independently configured for HDLC, transparent, or UART operation, allowing a single device to terminate a T1 on one channel and present Ethernet on another without external glue logic. The QUICC DMA engine handles line-rate bit stuffing and CRC, eliminating CPU interrupts at high baud. With commercial-grade temperature rating and 5V tolerance, the part fits central-office and outside-plant enclosures where 3.3V-only modern parts would require additional level shifting.

Serial-to-Ethernet Device Servers
Serial-to-Ethernet device servers use the MC68EN360ZQ33L to encapsulate RS-232/RS-485 traffic over TCP/IP. The two SMCs and the SPI controller drive multi-drop RS-485 ports, while the integrated Ethernet MAC provides the LAN uplink. The CPU32+ runs a lightweight IP stack and socket manager, with the QUICC engine handling continuous serial framing. The 357-BGA package supports compact board layouts that fit inside DIN-rail enclosures, and the 5V supply matches existing industrial backplanes. Compared with microcontroller + external MAC solutions, the integrated approach reduces latency and frees CPU cycles for protocol conversion.

Point-of-Sale (POS) Terminals
POS terminals rely on the MC68EN360ZQ33L for secure payment processing, receipt printing, and Ethernet/IP backhaul. The I2C controller interfaces with secure PIN pads and smart-card readers, the SPI drives the thermal printer, the parallel port connects to the LCD and keypad, and the Ethernet MAC handles IP-based transaction upload. The QUICC engine offloads encryption and serial framing, leaving the CPU32+ available for application logic. Its commercial temperature range and 5V tolerance suit retail environments where industrial-grade parts are unnecessary but reliability is mandatory.

Industrial Ethernet Gateways
Industrial Ethernet gateways that translate between Profibus, Modbus, DeviceNet, and TCP/IP benefit from the MC68EN360ZQ33L's mix of SCCs, SMCs, and integrated Ethernet. The QUICC engine handles cyclic Profibus token passing deterministically, while the Ethernet MAC presents the gateway as a Modbus-TCP slave to the SCADA host. The 4K+4K caches absorb large device-database tables, and the 16-channel DMA moves data without CPU intervention. With surface-mount BGA assembly and proven long-term NXP/Freescale support through Rochester Electronics, this part suits industrial gateways with 10-20 year field-life requirements.

Embedded Networking Appliances
Embedded networking appliances such as VPN concentrators, print servers, and IP-based data loggers leverage the MC68EN360ZQ33L's balance of CPU performance, peripheral integration, and deterministic QUICC communication. The CPU32+ runs embedded Linux or RTOS embedded sources, the Ethernet MAC provides the WAN/LAN uplink, and the SCCs/SMCs connect to legacy peripherals. The integrated MMU supports protected-mode operating systems, while the 5V supply tolerates industrial power rails. For long-lifeCycle designs where migration risk is high, this mature processor provides proven firmware support across decades of deployed units.

Ghi chú thiết kế
The 357-BGA package at 1.27 mm pitch requires via-in-pad or dog-bone PCB fanout. Use 4-layer stack-up with continuous ground planes under the BGA to control impedance for the MII (50 ohm to PHY) and DRAM bus (matched-length routing across byte lanes). Decoupling: 0.1 uF X7R ceramic cap within 5 mm of every power-pin cluster, plus 47-100 uF tantalum bulk on each 5V rail. Estimated: a 4-layer FR-4 board with proper stack-up yields ~70 ohm differential for MII signals, which is acceptable for 100 Mbps Ethernet.
The MC68EN360ZQ33L dissipates approximately 1.5-2.0 W under full load (33 MHz CPU + active Ethernet + multiple SCCs at line rate). The 357-BGA theta_JA is typically ~25 C/W on a 4-layer JEDEC test board, yielding a junction-to-ambient rise of ~50 C. For enclosed industrial cabinets at 60 C ambient, ensure at least 10 sq cm of copper pour directly under the BGA, or attach a small clip-on heatsink. Avoid placing the BGA directly above a sealed enclosure's bottom plate without thermal vias.
Three common pitfalls when designing with the MC68EN360ZQ33L: (1) Do not assume the part is RoHS-compliant - it contains lead in the BGA balls, and lead-free reflow profiles will damage it. (2) Do not enable both an SCC and the Ethernet MAC on overlapping DMA channels without configuring channel priority in the QUICC parameter RAM, or buffer corruption will occur. (3) Do not omit the external PHY's clock-to-MAC skew budget - the QUICC MII expects the RX_CLK within +/- 8 ns of the data, which requires source-synchronous routing on the PCB.
