Product details
Overview
MC68360CZP25L from Freescale Semiconductor is a quad integrated communications controller (QUICC) featuring a 25 MHz CPU32+ core, dual-port RAM, and an autonomous Communications Processor Module (CPM) supporting four serial channels including SCCs and SMCs. It integrates system control, memory management, and IEEE 1149.1 JTAG test access for embedded telecom and industrial protocol gateway applications.
For engineers reviewing the MC68360CZP25L datasheet, MC68360CZP25L pinout, MC68360CZP25L application, or MC68360CZP25L equivalent, key selection considerations include CPM-based offload capability, 25 MHz synchronous operation, glueless bus interface support, and compatibility with legacy MC68302-based designs requiring enhanced serial I/O density and deterministic real-time response.
Technical Context
The MC68360CZP25L implements a tightly coupled architecture where the CPU32+ core executes main application code while the CPM handles serial protocol processing-including HDLC, SDLC, UART, and transparent modes-via dedicated RISC microcode executed from on-chip dual-port RAM. Its SIM60 module provides clock generation, reset control, interrupt arbitration, and chip select logic with programmable timing.
It supports dynamic bus sizing (8/16/32-bit), misaligned operand access, and synchronous/asynchronous bus cycles with DSACK-based termination. The CPM operates independently using its own 25 MHz clock domain and shares dual-port RAM with the CPU for descriptor and buffer exchange without CPU intervention.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | CPU32+, 25 MHz maximum frequency - enables deterministic real-time execution of control-plane tasks in protocol gateways. |
| CPM Architecture | Autonomous RISC-based communications processor - offloads serial protocol handling (HDLC/UART/SDLC) from main CPU to reduce latency and CPU load. |
| Dual-Port RAM | 4 KB on-chip, shared between CPU and CPM - allows zero-copy data exchange for transmit/receive descriptors and buffers. |
| Serial Interfaces | 4 channels: 2 SCCs + 2 SMCs - supports simultaneous multi-protocol operation (e.g., T1/E1 framing + RS-232 + HDLC link layer). |
| Bus Interface | 32-bit multiplexed address/data bus, glueless design - simplifies host interface with no external bus logic required for standard memory-mapped peripherals. |
| JTAG Support | IEEE 1149.1 compliant TAP controller - enables boundary-scan testing and in-circuit debugging without halting CPU or CPM operation. |
| Power Supply | 5 V ±10% VCC, separate VCCSYN/GNDSYN and VCCCLK/GNDCLK domains - supports mixed-signal noise isolation for timing-critical serial interfaces. |
Pinout & Package
MC68360CZP25L is housed in a 256-pin Plastic Quad Flat Pack (PQFP) package with 0.65 mm pitch, designed for surface-mount assembly and thermal reliability in industrial temperature range (–40°C to +85°C). Pin assignments follow Freescale's standardized QUICC signal grouping for address/data multiplexing, peripheral control, and clock distribution.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A27–A0 | Address Bus (multiplexed) | Lower 28 address bits shared with D31–D0 during AD phase - requires external latch (e.g., 74LCX573) for demultiplexing in non-multiplexed mode. |
| D31–D0 | Data Bus (multiplexed) | 32-bit bidirectional data path - supports byte/word/dword transfers with WE0–WE3 enabling selective byte writes. |
| CS6–CS0/RAS6–RAS0 | Chip Select / Row Address | Seven independent chip selects with programmable timing - configures memory-mapped peripherals and DRAM banks without glue logic. |
| SCC1_Tx / SCC1_Rx | Serial Channel Controller 1 I/O | Differential or single-ended serial interface pins - configurable for HDLC, SDLC, or transparent mode with CPM-managed framing and CRC. |
| CLKO1 / CLKO2 | System Clock Outputs | Programmable clock outputs derived from internal PLL - drives external PHYs, transceivers, or synchronous peripherals at precise frequencies. |
| TCK / TMS / TDI / TDO | JTAG Test Access Port | IEEE 1149.1 boundary-scan interface - enables production test, debug, and firmware update without dedicated debug headers. |
Key Features
| Feature | Design Value |
|---|---|
| Glueless System Integration | Eliminates external bus logic by integrating chip select decoders, wait-state generators, and burst transfer control in SIM60 - reduces BOM cost and PCB area. |
| CPM-Based Protocol Offload | Enables concurrent HDLC, UART, and transparent serial protocols without CPU polling or interrupts - improves determinism in real-time communication stacks. |
| Dual-Port RAM Sharing | Allows CPU and CPM to access 4 KB RAM simultaneously via separate ports - avoids bus contention and enables lock-free descriptor ring management. |
| Dynamic Bus Sizing | Automatically adapts to 8-, 16-, or 32-bit peripheral widths using SIZ1/SIZ0 signals - simplifies integration with mixed-width legacy peripherals. |
| Background Debug Mode (BDM) | Provides non-intrusive debugging via BKPT/DSCLK pins - permits full visibility into CPU and CPM state without halting real-time serial traffic. |

The MC68360CZP25L is rated for a maximum CPU32+ core clock frequency of 25 MHz, with all internal modules-including the CPM, SIM60, and dual-port RAM-fully specified to operate reliably at this speed under industrial temperature conditions (–40°C to +85°C). This frequency is enforced by the external crystal oscillator circuit connected to XTAL/EXTAL pins and validated in Freescale's electrical characteristics section.
Does the MC68360CZP25L support JTAG debugging?
Yes, the MC68360CZP25L includes a fully compliant IEEE 1149.1 Test Access Port (TAP) controller with dedicated TCK, TMS, TDI, TDO, and TRST pins. This enables boundary-scan testing, in-circuit emulation, and non-intrusive debugging of both the CPU32+ core and CPM subsystem without disrupting real-time serial traffic handled by the MC68360CZP25L.
How many serial communication channels does the MC68360CZP25L provide?
The MC68360CZP25L integrates four independent serial channels: two Serial Communication Controllers (SCCs) and two Serial Management Controllers (SMCs).
