Product details
Overview
MC68360VR25VL from Freescale Semiconductor is a 32-bit integrated communications controller (QUICC™) combining CPU32+ core, System Integration Module (SIM60), and Communications Processor Module (CPM) in a single PQFP-240 package. It delivers 4.5 MIPS at 25 MHz, supports four SCCs, two SMCs, one SPI, dual TDM buses, and operates across –40°C to +85°C for industrial telecom edge nodes.
For engineers reviewing the MC68360VR25VL datasheet, MC68360VR25VL pinout, MC68360VR25VL application, or MC68360VR25VL equivalent, key selection considerations include its quad-SCC HDLC/SDLC support up to 2 Mbps per channel, slave-mode compatibility with MC68040-family processors, and on-chip 2.5 KB dual-port RAM for CPM buffer descriptor management.
Technical Context
The MC68360VR25VL implements a tightly coupled dual-processor architecture: the CPU32+ core handles general-purpose execution while the RISC-based CPM offloads serial protocol processing-including HDLC, UART, BISYNC, and transparent bit-stream modes-using 224 buffer descriptors and dedicated IDMA controllers. Its SIM60 provides bus arbitration, clock synthesis, periodic interrupt timer, and IEEE 1149.1 JTAG test access.
It features dynamic bus sizing (8/16/32-bit), 28+ address lines, four general-purpose timers (configurable as four 16-bit or two 32-bit), and a time-slot assigner enabling independent transmit/receive routing across two TDM buses supporting T1, CEPT, ISDN, and user-defined formats at 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 | Identical architecture but in 241-pin PGA package; includes Ethernet MAC layer hardwired to SCC1; same 25 MHz rating and –40°C to +85°C range | Preferred for high-vibration environments where PGA mechanical stability outweighs PQFP board-space efficiency | Select MC68EN360RC25 only when requiring pin-compatible Ethernet PHY integration and board-level shock resistance beyond PQFP capabilities |
| MPC860TVR25B | PowerPC 603e core (up to 66 MHz), QUICC II architecture, integrated FEC Ethernet, but no TDM time-slot assigner or SMC peripherals | Targets higher-throughput routing with integrated 10/100 Mbps Ethernet, but lacks native T1/CEPT or AppleTalk support present in MC68360VR25VL | Choose MPC860TVR25B for new designs needing >10 Mbps routed throughput; retain MC68360VR25VL for legacy protocol continuity and TDM flexibility |
Compared with MC68EN360RC25, MC68360VR25VL offers superior PCB area efficiency and thermal performance in PQFP form, while MPC860TVR25B trades legacy serial protocol breadth for raw packet-processing speed and modern Ethernet integration - making MC68360VR25VL irreplaceable for TDM-centric or multi-protocol edge node upgrades.

FAQ
What is the maximum serial data rate supported by each SCC on the MC68360VR25VL?
The MC68360VR25VL supports up to 2 Mbps per SCC channel for HDLC/SDLC operation, as confirmed in the official MC68360 Product Brief and User's Manual. This rate applies to all four SCCs simultaneously under full CPM load, with hardware CRC generation and bit-stuffing handled autonomously. The MC68360VR25VL does not support higher rates like 10 Mbps on SCC1 unless paired with the MC68EN360 variant, which integrates additional Ethernet MAC logic not present in the base MC68360VR25VL.
Does the MC68360VR25VL include an integrated Ethernet MAC?
No, the MC68360VR25VL does not include a hardware Ethernet MAC. While SCC1 can be configured for IEEE 802.3 framing in software-defined mode, full Ethernet PHY interface requires external transceiver and media access control logic. Only the MC68EN360 variant - explicitly designated with "EN" in the part number - adds hardwired Ethernet MAC functionality to SCC1. The MC68360VR25VL relies on CPM-managed HDLC framing for Ethernet-like packetization but lacks dedicated MAC registers or MII interface signals.
Can the MC68360VR25VL operate without external memory?
Yes, the MC68360VR25VL can execute basic initialization and CPM setup from internal resources: it contains 2.5 KB of dual-port RAM exclusively allocated to the CPM for buffer descriptors and parameter RAM, and the CPU32+ core supports ROM-based boot from CS0-mapped EPROM or Flash. However, full application code execution and runtime data storage require external memory - the MC68360VR25VL has no internal program or data SRAM beyond the CPM's dedicated RAM block.
What is the function of the time-slot assigner in the MC68360VR25VL?
The time-slot assigner in the MC68360VR25VL dynamically maps individual time slots from two independent TDM buses (TDM Bus 1 and TDM Bus 2) to any of the six serial channels - four SCCs and two SMCs. It supports T1, CEPT, ISDN, and user-defined formats with 1- or 8-bit resolution, and enables independent transmit/receive routing, frame sync generation, and clock sourcing per channel. This allows the MC68360VR25VL to serve as a T1-to-ISDN converter or voice/data multiplexer without external TSI chips.
Is the MC68360VR25VL pin-compatible with the MC68302?
No, the MC68360VR25VL is not pin-compatible with the MC68302. The MC68360VR25VL uses a 240-pin PQFP package with 0.5 mm pitch, whereas the MC68302 uses a 132-pin package with different signal allocation and timing. The Product Brief explicitly states "Pinout-The pinout is not the same" and notes that the QUICC's increased functionality results in more multifunctional pins than the MC68302. Migration requires complete PCB redesign, though software drivers for CPM peripherals retain significant structural similarity.
