Product details
Overview
MC68360ZQ33L from Freescale Semiconductor is a 32-bit integrated microprocessor and communications controller featuring the CPU32+ core, System Integration Module (SIM60), and Communications Processor Module (CPM). It delivers 4.5 MIPS at 25 MHz, supports up to 32-bit data/32-bit address buses, and integrates four SCCs, two SMCs, one SPI, dual TDM support, and two independent DMAs - enabling high-throughput serial protocol handling in telecom infrastructure and industrial control systems.
For engineers reviewing the MC68360ZQ33L datasheet, MC68360ZQ33L pinout, MC68360ZQ33L application, or MC68360ZQ33L equivalent, this page provides verified technical context, validated pin functions, confirmed communication protocol support (HDLC/SDLC, UART, SPI, TDM), real-world use cases, and traceable alternative options for legacy design migration and long-life embedded deployments.
Technical Context
The MC68360ZQ33L implements a three-module architecture: CPU32+ core (M68000-compatible, 4.5 MIPS @25 MHz), SIM60 (with DRAM controller, IEEE 1149.1 JTAG, periodic timer, and slave mode support), and CPM (RISC-based communications engine with 224 buffer descriptors and autonomous serial channel management).
Its serial subsystem includes seven channels - four SCCs (supporting HDLC/SDLC up to 2 Mbps, Ethernet on SCC1 only in MC68EN360 variants), two SMCs (UART/GCI/TDM), and one SPI (master/slave/multimaster) - all coordinated by a time-slot assigner enabling dynamic routing across two independent TDM buses with 1- or 8-bit resolution.

Equivalent & Alternatives
The following parts are listed as comparable options for similar integrated communications controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC68EN360RC25 | Same CPU32+/SIM60/CPM architecture but adds Ethernet MAC on SCC1; offered in PGA package (240-pin) at same 25 MHz rating | Required where native 10-Mbps Ethernet PHY interface is needed without external MAC; not pin-compatible due to different package and signal routing | Select MC68EN360RC25 only when Ethernet MAC functionality is mandatory and PCB redesign is acceptable |
| MPC8260AZUUPEA | PowerQUICC II processor with G2 core (266 MHz), integrated SEC, and dual Fast Ethernet MACs - no CPM or SCC/SMC legacy compatibility | Targets modern high-speed gateway designs requiring crypto acceleration and Gigabit-ready interfaces; lacks direct SCC register mapping or BD architecture | Choose MPC8260AZUUPEA for new designs needing >10× performance uplift and security offload - not for MC68360ZQ33L drop-in replacement |
Compared with MC68EN360RC25, MC68360ZQ33L offers identical communications architecture without Ethernet MAC overhead, reducing power and complexity for non-Ethernet TDM/HDLC applications; versus MPC8260AZUUPEA, it provides proven long-lifecycle support and direct firmware portability from MC68302-based systems, critical for maintenance-only industrial deployments.

FAQ
What is the maximum operating frequency of the MC68360ZQ33L?
The MC68360ZQ33L is rated for operation up to 25 MHz. Its fully static CPU32+ core allows reliable function across the full 0–25 MHz range, with verified timing margins per the MC68360UM/AD specification. The "33L" suffix denotes a 25 MHz speed grade and industrial temperature range (–40°C to +85°C); operation beyond 25 MHz is not supported and violates AC timing parameters.
Does the MC68360ZQ33L include an integrated Ethernet MAC?
No, the MC68360ZQ33L does not include an integrated Ethernet MAC. Ethernet capability is exclusive to the MC68EN360 variant (e.g., MC68EN360EM25), which adds IEEE 802.3 support on SCC1. The MC68360ZQ33L supports all other QUICC protocols - HDLC/SDLC, UART, SPI, TDM - but requires an external Ethernet PHY and MAC controller for LAN connectivity.
Is the MC68360ZQ33L pin-compatible with the MC68302?
No, the MC68360ZQ33L is not pin-compatible with the MC68302. It uses a 240-pin PQFP package with 20-mil pitch, whereas the MC68302 uses a 132-pin package with 25-mil pitch. Hardware redesign is required for migration; however, the CPM buffer descriptor structure, SCC command set, and CPU32+ instruction set provide strong software compatibility for firmware porting.
What development tools are officially supported for the MC68360ZQ33L?
Officially supported tools for the MC68360ZQ33L include the M68000 Family Programmer's Reference Manual (M68000PM/AD), MC68360 User's Manual (MC68360UM/AD), and third-party BDM debuggers compatible with CPU32+ background debug mode. Freescale's CodeWarrior Development Studio v5.x and earlier versions provided native MC68360ZQ33L support, including CPM initialization libraries and SCC parameter RAM templates.
How does the CPM in the MC68360ZQ33L reduce CPU load during serial communications?
The CPM in the MC68360ZQ33L reduces CPU load by executing serial protocol processing autonomously using its RISC controller and 224 on-chip buffer descriptors. It handles HDLC flag detection, CRC generation/checking, frame assembly/disassembly, and DMA transfers - allowing the CPU32+ core to remain idle or process higher-level tasks while serial I/O proceeds without intervention.
