Product details
Overview
MC68EN360VR25VL from Freescale Semiconductor is a 25 MHz QUICC™ (Quad Integrated Communication Controller) IC integrating CPU32+ core, System Integration Module (SIM60), and Communications Processor Module (CPM). It delivers 4.5 MIPS, supports four SCCs (including Ethernet/IEEE 802.3 on SCC1), two SMCs, one SPI, dual TDM buses, and operates across –40°C to +85°C for industrial communications gateways and protocol bridges.
For engineers reviewing the MC68EN360VR25VL datasheet, MC68EN360VR25VL pinout, MC68EN360VR25VL application, or MC68EN360VR25VL equivalent, key selection criteria include its 240-pin PQFP package, 25 MHz max clock, slave mode support for MC68040 companion operation, and verified Ethernet-capable SCC1 channel - all critical for legacy telecom controller upgrades and deterministic serial protocol aggregation.
Technical Context
The MC68EN360VR25VL implements a tightly coupled dual-module architecture: the CPU32+ core handles general-purpose execution while the RISC-based CPM offloads serial protocol processing (HDLC, UART, BISYNC, transparent bit-stream) using 224 buffer descriptors and independent IDMA channels. Its SIM60 provides system-level services including bus arbitration, periodic interrupt timer, software watchdog, and IEEE 1149.1 JTAG test access.
It features dynamic bus sizing (8/16/32-bit), 32 address lines (≥28 always available), DRAM controller with RAS/CAS support, and time-slot assigner enabling independent transmit/receive routing across two TDM buses - each configurable for T1, CEPT, ISDN Basic/Primary Rate, or user-defined PCM formats.

Equivalent & Alternatives
The following parts are listed as comparable options for similar integrated communication controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC68EN360RC25 | Identical core, CPM, and SIM60 functionality; differs only in PGA package (240-pin Pin Grid Array) instead of PQFP | Preferred for high-vibration environments requiring mechanical stability; less suitable for automated SMT assembly | Select MC68EN360RC25 when board-level shock resistance >15 g is required or when existing tooling supports PGA reflow profiles |
| MC68360EM25 | Lacks Ethernet-capable SCC1; no IEEE 802.3 support; otherwise identical CPU32+, CPM, and SIM60 specs at 25 MHz | Suitable for non-Ethernet serial concentrators (e.g., HDLC-only base station controllers) where cost reduction outweighs Ethernet feature need | Choose MC68360EM25 only if Ethernet PHY interface is implemented externally or not required - saves $12.40/unit at 1k volume |
Compared with MC68EN360RC25, MC68EN360VR25VL offers identical electrical and functional behavior in a surface-mount PQFP package optimized for automated manufacturing; versus MC68360EM25, it adds essential IEEE 802.3 Ethernet capability on SCC1 - a hardware-differentiated feature unavailable via firmware upgrade.

FAQ
Does MC68EN360VR25VL support IEEE 802.3 Ethernet, and which serial channel provides it?
Yes, MC68EN360VR25VL supports full 10-Mbps IEEE 802.3 Ethernet exclusively on SCC1. This capability is a hardware-differentiated feature of the "EN" variant (vs. standard MC68360), requiring no microcode or external logic. The SCC1_TXD/SCC1_RXD pins drive an external Ethernet PHY, and the CPM handles MAC-layer framing and CRC generation in hardware.
What is the maximum operating frequency and temperature range for MC68EN360VR25VL?
The MC68EN360VR25VL is rated for 25 MHz maximum clock frequency and operates across –40°C to +85°C. This specification is validated per Freescale's industrial qualification standards and applies to all functional blocks - CPU32+, SIM60, and CPM - under worst-case voltage and process corners.
How does MC68EN360VR25VL differ from MC68360EM25 in terms of Ethernet capability?
MC68EN360VR25VL includes hardware-enabled IEEE 802.3 Ethernet support on SCC1, whereas MC68360EM25 lacks this feature entirely. No microcode or external components can add Ethernet to MC68360EM25 - the EN-series silicon contains dedicated Ethernet signal routing and timing logic absent in the base MC68360 mask set.
Can MC68EN360VR25VL operate as a peripheral to an external processor, and what modes support this?
Yes, MC68EN360VR25VL supports slave mode operation, enabling use as an intelligent communications peripheral. It implements MC68040 companion mode - allowing seamless integration with MC68EC040 or MC68040 hosts - and general slave mode for any MC68030-compatible bus master. In both cases, the CPU32+ is disabled while SIM60 and CPM remain fully functional.
What package type and pin count does MC68EN360VR25VL use, and is it pin-compatible with other MC68EN360 variants?
MC68EN360VR25VL uses a 240-pin Plastic Quad Flat Pack (PQFP) with 20-mil pitch. It shares identical pinout and signal mapping with MC68EN360EM25 (same PQFP) and MC68EN360RC25 (same 240-pin count but PGA package), ensuring PCB layout compatibility across the EN-series family for drop-in replacement within same package type.
