Product details
Overview
MC68EN360ZP25VL from Freescale Semiconductor is a quad integrated communications controller (QUICC) featuring a 32-bit CPU32+ core, dual-ported RAM, and an autonomous Communications Processor Module (CPM) for offloading serial protocol handling. It operates at 25 MHz, supports IEEE 1149.1 JTAG test access, and integrates UART, SCC, SMC, and I²C peripherals - used in industrial gateways requiring deterministic real-time communication control.
For engineers reviewing the MC68EN360ZP25VL datasheet, MC68EN360ZP25VL pinout, MC68EN360ZP25VL application, or MC68EN360ZP25VL equivalent, key selection criteria include CPM-based serial offload capability, 25 MHz system clock timing, dual-port RAM size (8 KB), and compatibility with legacy MC68302-based designs.
Technical Context
The MC68EN360ZP25VL implements a split-processor architecture: the CPU32+ core handles main application tasks while the CPM independently manages up to four serial channels (SCC/SMC) using microcode-driven RISC engines. Its SIM60 module provides memory mapping, interrupt arbitration, and bus interface logic compliant with M68000-family timing.
It supports glueless interfacing to DRAM, SRAM, and peripheral devices via a 32-bit multiplexed address/data bus, with configurable chip selects, programmable wait states, and dynamic bus sizing for 8/16/32-bit transfers - enabling direct integration into legacy 68k-based industrial control systems without external bus logic.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | CPU32+, 32-bit M68000-family instruction set compatible, enables reuse of existing 68k toolchains and firmware. |
| Max Clock Frequency | 25 MHz - defines maximum instruction throughput and CPM serial baud rate ceiling (e.g., 2.5 Mbps on SCC). |
| Dual-Port RAM | 8 KB on-chip - shared between CPU and CPM with hardware arbitration, eliminating external FIFOs for protocol buffering. |
| CPM Peripherals | 4x Serial Communication Controllers (SCC), 2x Serial Management Controllers (SMC), 1x I²C, 1x USB-like parallel port - enables concurrent HDLC, UART, and bisync link management. |
| JTAG Support | IEEE 1149.1 compliant TAP controller - enables boundary-scan testing and in-circuit debugging without halting CPU or CPM operation. |
| Bus Interface | 32-bit multiplexed address/data bus with 4-byte write enable, DSACK handshaking, and dynamic sizing - supports direct connection to standard SRAM/DRAM without glue logic. |
| Power Supply | 5.0 V ±5% - matches legacy 68k system rails; no separate I/O or core voltage domains required. |
Pinout & Package
MC68EN360ZP25VL is housed in a 256-pin Plastic Quad Flat Pack (PQFP) package with 0.65 mm pitch, designed for surface-mount assembly and thermal dissipation in industrial temperature-grade applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A27–A0 | Address Bus (Multiplexed) | 28-bit address output during AS assertion; used for memory/peripheral decode in 32-bit address space. |
| D31–D0 | Data Bus (Multiplexed) | 32-bit bidirectional data path; byte-enable signals (WE3–WE0) allow partial writes without read-modify-write cycles. |
| AS | Address Strobe | Indicates valid address on A27–A0; initiates bus cycle timing for memory or peripheral access. |
| DS | Data Strobe | Valid during data transfer phase; synchronized with DSACK to confirm data sampling window. |
| RESETS | Soft Reset Input | Asynchronous reset of CPU and CPM logic only; preserves contents of dual-port RAM and configuration registers. |
| EXTAL/XTAL | Crystal Oscillator Inputs | Supports fundamental-mode quartz crystal (25 MHz) or external clock source for system timing reference. |
| TCK/TMS/TDI/TDO | JTAG Test Interface | Enables IEEE 1149.1 boundary scan, device programming, and real-time debug without CPU intervention. |
Key Features
| Feature | Design Value |
|---|---|
| Autonomous CPM | Offloads UART, HDLC, bisync, and I²C protocol processing from CPU, freeing >40% of CPU bandwidth for application tasks. |
| Dual-Port RAM Arbitration | Hardware-mutexed 8 KB RAM allows simultaneous CPU read/write and CPM DMA access with zero-cycle conflict resolution. |
| Glueless Bus Interface | Native support for DRAM refresh, SRAM wait-state insertion, and chip-select decoding eliminates need for external PAL/GAL logic. |
| Background Debug Mode (BDM) | On-chip debug interface enables non-intrusive breakpoint setting, register inspection, and flash programming via BKPT/DSCLK pins. |
| Legacy MC68302 Upgrade Path | Pin-compatible memory map and register layout simplifies migration from MC68302 designs with minimal PCB or firmware changes. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad communications controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC68360ZP25VL | Same die, commercial temperature grade (0°C to +70°C); lacks EN prefix denoting extended industrial temp range. | Not rated for -40°C operation; unsuitable for outdoor or rail-mounted deployments. | Select MC68EN360ZP25VL when operating below 0°C or above 70°C is required. |
| MPC860TVR52D4 | PowerPC-based successor with integrated FEC Ethernet MAC, higher clock (52 MHz), but no native M68k compatibility or CPM microcode environment. | Requires full firmware rewrite; supports modern TCP/IP stacks but loses legacy protocol microcode libraries. | Choose MPC860TVR52D4 only when Ethernet connectivity and PowerPC toolchain adoption are priorities over backward compatibility. |
Compared with MC68360ZP25VL, the MC68EN360ZP25VL adds extended temperature qualification (-40°C to +85°C) critical for harsh environments, while the MPC860TVR52D4 trades CPM-based serial offload for integrated Ethernet and higher performance - making it suitable for next-gen designs but incompatible with legacy QUICC firmware.

FAQ
What is the operating temperature range of the MC68EN360ZP25VL?
The MC68EN360ZP25VL is specified for industrial temperature operation from –40°C to +85°C. This extended range distinguishes it from the commercial-grade MC68360ZP25VL (0°C to +70°C) and makes it suitable for deployment in outdoor enclosures, rail vehicles, and utility substations where ambient conditions exceed standard commercial limits. The "EN" prefix in MC68EN360ZP25VL explicitly denotes this extended qualification.
Does the MC68EN360ZP25VL support JTAG boundary-scan testing?
Yes, the MC68EN360ZP25VL includes a fully compliant IEEE 1149.1 Test Access Port (TAP) controller with dedicated TCK, TMS, TDI, and TDO pins. This enables board-level boundary-scan testing, in-system programming, and non-intrusive debugging without halting the CPU32+ core or CPM operation - a key requirement for high-reliability industrial manufacturing and field maintenance workflows involving the MC68EN360ZP25VL.
How does the CPM in the MC68EN360ZP25VL reduce CPU overhead?
The CPM in the MC68EN360ZP25VL contains a dedicated RISC microengine that executes protocol-specific microcode for UART, HDLC, bisync, and I²C - handling framing, CRC generation, and DMA without CPU intervention. This offloads ~40–60% of serial processing from the CPU32+ core, allowing the MC68EN360ZP25VL to sustain multiple concurrent serial links while maintaining deterministic response for time-critical application tasks.
Is the MC68EN360ZP25VL pin-compatible with the MC68302?
No, the MC68EN360ZP25VL is not pin-compatible with the MC68302 due to its larger 256-pin PQFP footprint and expanded peripheral set. However, it provides architectural and register-level compatibility: memory maps, CPM register layout, and CPU32+ instruction set align with MC68302 software, enabling straightforward firmware migration - though PCB redesign is required to accommodate the MC68EN360ZP25VL's physical interface.
What type of external memory interface does the MC68EN360ZP25VL support?
The MC68EN360ZP25VL supports a 32-bit multiplexed address/data bus with seven chip selects (CS0–CS6), programmable wait-state insertion, DRAM row/column addressing, and dynamic bus sizing for 8-, 16-, and 32-bit peripherals. It interfaces directly with standard SRAM, DRAM, and flash devices without external glue logic - a feature confirmed in Section 4 of the MC68360 User's Manual and validated in MC68EN360ZP25VL reference schematics.
