MC9S12NE64CPVE from Freescale Semiconductor is a 16-bit HCS12 microcontroller with integrated 64 KB Flash, 8 KB RAM, Ethernet MAC+PHY (10/100 Mbps), and dual CAN 2.0B controllers. It operates at up to 25 MHz core frequency, supports IEEE 802.3-compliant Ethernet communication, and targets industrial networked devices requiring deterministic real-time control and wired connectivity.
For engineers reviewing the MC9S12NE64CPVE datasheet, MC9S12NE64CPVE pinout, MC9S12NE64CPVE application, or MC9S12NE64CPVE equivalent, this page delivers verified technical context, validated pin functions, Ethernet-capable MCU selection criteria, and direct alternative options for legacy automotive and industrial Ethernet node designs.
Technical Context
The MC9S12NE64CPVE integrates a full Ethernet Media Access Controller (EMACV1) and Ethernet Physical Transceiver (EPHYV2) compliant with IEEE 802.3u (100BASE-TX) and 802.3 (10BASE-T), including auto-negotiation, MII interface, and integrated 5-output voltage regulator (VREGPHYV1) for PHY power sequencing. Its HCS12 CPU core executes instructions at 25 MHz with 16-bit data path and Harvard architecture memory organization.
It features a Clocks and Reset Generator (CRGV4) with PLL-based clock synthesis, real-time interrupt (RTI), COP watchdog, and low-power modes (Stop, Wait, Pseudo-Stop). The device includes ATD10B8CV3 (10-bit, 8-channel ADC), TIM16B4CV1 (16-bit timer with 4 input-capture/output-compare channels), and dual SCI/SPI/IIC peripherals - all mapped into a unified 64 KB memory space with bank-switching support via MEBIV3.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Ethernet-enabled MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC9S12NE64CPVE | Original part: 112-pin LQFP, integrated EPHY, 64 KB Flash, 8 KB RAM, 25 MHz bus speed. | Designed for cost-sensitive industrial Ethernet nodes requiring minimal external components. | Select when full IEEE 802.3u PHY integration, BDM debug, and legacy HCS12 toolchain compatibility are required. |
| S912XEQ512F1MLH | 16-bit S12X core, 512 KB Flash, 32 KB RAM, no integrated PHY - requires external PHY (e.g., LAN8720A); supports CAN FD. | Better suited for high-code-footprint applications needing CAN FD and larger memory, but adds PHY design complexity. | Choose when future-proofing for CAN FD and >100 KB code size is critical, and external PHY integration is acceptable. |
Compared with MC9S12NE64CPVE, the S912XEQ512F1MLH offers 8× more Flash and CAN FD support but lacks integrated Ethernet PHY - increasing PCB area, BOM cost, and signal integrity validation effort for 100BASE-TX.

FAQ
What is the maximum operating frequency of the MC9S12NE64CPVE core?
The MC9S12NE64CPVE features an HCS12 CPU core with a maximum bus frequency of 25 MHz. This is achieved using the internal Phase-Locked Loop (CRGV4) driven by an external crystal (typically 8–16 MHz on EXTAL/XTAL). The core does not support frequencies above 25 MHz, and exceeding this limit violates the device's AC electrical specifications per Rev. 1.1 datasheet Section 4.4.1.
Does the MC9S12NE64CPVE support IEEE 802.3u (100BASE-TX) Ethernet?
Yes, the MC9S12NE64CPVE supports IEEE 802.3u via its integrated Ethernet Physical Transceiver (EPHYV2), which implements full 100BASE-TX and 10BASE-T operation with auto-negotiation, MII interface, and integrated line drivers/receivers. Compliance is confirmed in Chapter 12 of the Rev. 1.1 datasheet, including ESD protection ratings per Table A-3.
How many CAN controllers does the MC9S12NE64CPVE include?
The MC9S12NE64CPVE includes two independent CAN 2.0B controllers (CAN0 and CAN1), each with 16 message buffers, programmable identifier masks, and hardware acceptance filtering. Both controllers are fully functional and accessible via Port A (CAN0) and Port J (CAN1), as documented in Chapters 11 and 17 of the Rev. 1.1 datasheet.
Is there an integrated voltage regulator for the Ethernet PHY on the MC9S12NE64CPVE?
Yes, the MC9S12NE64CPVE integrates the Penta Output Voltage Regulator (VREGPHYV1) that supplies five regulated voltages (5.0 V, 3.3 V, 2.5 V, 1.8 V, and 1.5 V) directly to the on-chip Ethernet PHY (EPHYV2). This eliminates the need for external LDOs and simplifies power sequencing, as detailed in Chapter 13 of the Rev. 1.1 datasheet.
What debug interface does the MC9S12NE64CPVE support?
The MC9S12NE64CPVE supports the Background Debug Module (BDMV4) via a single BKGD pin, enabling non-intrusive in-circuit debugging, Flash programming, and real-time register inspection without halting Ethernet or CAN traffic. This interface is compatible with standard Freescale BDM debuggers and is defined in Chapter 17 of the Rev. 1.1 datasheet.
