MC9S12NE64VTUE - 16-bit HCS12 MCU, 64KB Flash, Ethernet | NXP
料号： MC9S12NE64VTUE ✗ 停产MC9S12NE64VTUE 概述
A microcontroller (MCU) is a single-chip computer that integrates a CPU, memory (Flash/RAM), and peripherals onto one silicon die. The HCS12 is the 16-bit successor of Freescale's HC11 architecture, and the S12 family occupies the mid-tier between 8-bit MCUs (8-bit -> 16-bit -> 32-bit microcontroller hierarchy) and high-end 32-bit ARM Cortex-M parts. The 'NE' sub-family specifically adds an on-chip 10/100 Mbps Ethernet MAC + PHY, eliminating the need for an external network interface chip in connected-embedded designs.
Key features of the MC9S12NE64VTUE include: 64 KB program Flash, 8 KB SRAM, hardware IEEE 802.3 Ethernet MAC with 10/100 PHY on-chip, dual CAN 2.0 controllers (msCAN), three SCI (UART) channels, one SPI, one I2C, an 8-channel 10-bit ADC, a 16-bit timer with 8 PWM channels, and a background debug module (BDM) for in-circuit programming and debug. The 80-pin TQFP-EP package is small enough for compact embedded boards while exposing ample GPIO and bus lines for industrial connectivity.
The architecture is built on the standard HCS12 CPU core with a 16-bit data path, indexed addressing, and a memory-mapped register model. The integrated Ethernet subsystem follows the IEEE 802.3 specification, with the MAC performing CSMA/CD framing and the embedded PHY handling line-side analog signaling (MLT-3 on the twisted pair, auto-negotiation, link integrity). The 25 MHz system clock is derived from an internal Phase-Locked Loop (IPLL) from an external crystal. Background Debug Mode (BDM) allows flash programming and real-time debug over a single-wire interface.
Typical applications include industrial Ethernet gateways, building-automation controllers (BACnet/IP, Modbus-TCP), sensor-to-cloud bridges, embedded web servers for SCADA integration, and automotive telematics prototyping where CAN-to-Ethernet routing is needed.
Designers should note that VDD/VDDX decoupling must be placed within 5 mm of each supply pin, and the 25 MHz crystal loop requires short, symmetrical traces. The on-chip EMAC + PHY removes the BOM cost of an external network controller but adds approximately 50 mA of additional supply current during active link transmission.

典型应用
MC9S12NE64VTUE 适用于 6 应用s: Industrial Ethernet Gateway / SCADA Node, Building Automation Controller (BACnet/IP / Modbus-TCP), Sensor-to-Cloud IoT Edge Bridge, Embedded Web Server / Web-Interface Equipment, Automotive Telematics / CAN-to-Ethernet Router (Prototype Only), Remote Sensor Monitoring in Power Utilities.
Industrial Ethernet Gateway / SCADA Node
The MC9S12NE64VTUE is purpose-built for compact industrial Ethernet gateways because its integrated 10/100 Mbps IEEE 802.3 MAC+PHY eliminates the BOM cost of an external Ethernet controller. With 64 KB Flash and 8 KB SRAM, the part runs a Modbus-TCP or BACnet/IP server stack plus a CAN-to-Ethernet bridge - the on-chip dual msCAN controllers read field-bus traffic from a sensor, package it as UDP frames and push it up to a SCADA master. The 25 MHz HCS12 core delivers sufficient throughput for packet forwarding at modest node counts (10-50 sensors), while the VQFP-EP package's 14x14 mm footprint is small enough to fit inside an inline DIN-rail enclosure alongside a 1:1 isolation transformer and a 49.9 ohm termination network.
推荐
Building Automation Controller (BACnet/IP / Modbus-TCP)
For HVAC controllers and access-control panels needing a standards-compliant Ethernet interface, the MC9S12NE64VTUE combines the on-chip EMAC+PHY with three SCI (UART) channels that simultaneously talk RS-485 to lighting/HVAC field modules. The MCU's integrated 10/100 Ethernet MAC transparently handles the TCP/IP packetization, leaving the HCS12 CPU free to run the BACnet scheduling logic; in contrast to a discrete PHY+MCU solution, this single-chip approach cuts board area by ~40 percent. Per the Freescale/NXP datasheet, the PHY auto-negotiates link speed and duplex with the Ethernet switch, removing firmware state-machine logic for the link layer. Use cases include VAV boxes, thermostat controllers, and BACnet/IP routers in commercial buildings.
推荐
Sensor-to-Cloud IoT Edge Bridge
The MC9S12NE64VTUE serves as an IoT-edge device that bridges slow local sensors to a cloud MQTT broker over Ethernet, leveraging the on-chip EMAC+PHY to avoid pulling in a heavy network stack on a discrete MCU. The on-chip 8-channel 10-bit ADC reads thermocouples, pressure sensors or analog flow meters; SCI UARTs handle Modbus RTU to sub-instruments; the on-chip IEEE 802.3 stack publishes converted values to a Mosquitto broker on the LAN at polling intervals set by the user firmware. Compared to a discrete Ethernet PHY, the integrated PHY cuts standby power by 25-30 mW during idle-link states, an important efficiency bonus for always-on industrial-edge nodes.
推荐
Embedded Web Server / Web-Interface Equipment
The S12NE family's 16-bit HCS12 core plus its integrated TCP/IP-friendly EMAC make the MC9S12NE64VTUE suitable for embedded web servers that need to expose a simple HTML/Telnet interface to lab instruments or low-end printers. Designers commonly run the Freescale/NXP TCP/IP lite stack on this part and serve ~30 KB web pages, sufficient for device status, configuration and diagnostic logs. The on-chip EMAC+PHY removes the external-bus bandwidth bottleneck that an external MAC would impose on the 25 MHz CPU, allowing full 10/100 Mbps line-rate throughput on small frames.
推荐
Automotive Telematics / CAN-to-Ethernet Router (Prototype Only)
While the MC9S12NE64VTUE is only industrial-grade and not AEC-Q100 qualified, prototyping teams frequently use it as a CAN-to-Ethernet bridge for automotive telematics development benches because of its dual on-chip msCAN controllers and integrated Ethernet. The MCU can be pre-programmed to capture CAN traffic from an ECU development harness and stream it to a PC for analysis without requiring a separate OBD-II dongle. In production, designers should migrate to the AEC-Q100-qualified S12G family, but for lab, demo and proof-of-concept work the NE64 is a fast path to a working bridge.
推荐
Remote Sensor Monitoring in Power Utilities
The MC9S12NE64VTUE's industrial -40C to +105C temperature range and integrated Ethernet allow it to be deployed in outdoor substation monitoring cabinets and remote meter-telemetry boxes over twisted-pair Ethernet backhaul. The on-chip EMAC+PHY handles 10BASE-T/100BASE-TX line signaling across the typical 100 m cable run, while the part's 64 KB Flash holds both the protocol stack and the local averaging/sampling logic. With the integrated network interface, the designer avoids a separate PHY which would otherwise consume an additional 50-80 mW from the rail - non-trivial for solar-powered remote installations. Compared to a discrete solution, this single-chip approach also reduces PCB area by ~25 percent, helping in the constrained splicing-closure format factor.

设计说明
The 80-pin TQFP-EP relies on its bottom-side exposed thermal pad for heat removal. At 25 MHz core clock and simultaneous Ethernet transmission the worst-case power dissipation is ~340 mW per the Freescale/NXP datasheet. Recommended PCB: at least 8 thermal vias (0.3 mm drill, 0.6 mm pad) inside the EP land pattern, plus a 2 cm^2 copper pour on the top side and a 4 cm^2 solid ground plane on layer 2. Without these measures junction temperature will rise above 105C and the on-chip thermal protection will fire, suppressing Ethernet transmission. Estimated: assuming theta_JA ~35 C/W (4-layer, 1-oz copper, no airflow), 340 mW yields about 12 C rise above ambient - acceptable for the part's 105C industrial ceiling.
The Ethernet analog pins (ETH_TX+/-, ETH_RX+/-, RBIAS, REF_CLK) are noise-sensitive: keep the 49.9 ohm 1% termination resistors within 8 mm of the TQFP-EP pins, route the differential pair over a continuous ground plane with 100 ohm differential impedance, and never cross these signals with the HCS12 external bus (e.g. address/data lines). The RBIAS pin requires a precision 12.4 kohm 1% resistor to ground; poor selection here will bias the internal PHY current sources off-spec and force re-transmits. Keep the magnetics (1:1 isolation transformer) within 25 mm of the connector.
The MC9S12NE64VTUE requires two supplies: a 2.5 V VDD/PLL_VDD rail for the core and PLL, and a 3.3 V VDDX/EVDD rail for the I/O ring and Ethernet analog. Per the Freescale/NXP datasheet, both supplies must come up within a defined tracking window - VDD should reach 2.5 V first and VDDX second, or the on-chip voltage monitor holds the part in reset. Place 100 nF ceramic decoupling on every VDD/VDDX pin within 5 mm trace length, plus a 4.7 uF bulk capacitor on each rail. An estimated inrush current of ~250 mA per rail suggests using a soft-start regulator (e.g. TPS7A4701) for the 2.5 V line to avoid startup glitch on shared backplanes.
Do not attempt to re-program the MC9S12NE64VTUE with a non-BDM tool - the part does not expose JTAG and the S12 flash security bit can be locked out only via Background Debug Mode. Avoid driving ETH_RX+/- when the part is in reset or the PHY will latch a fault; gate these lines through the on-chip EMAC clock-enable if possible. Finally, do not exceed 25 MHz on EXTAL/XTAL - higher crystal frequencies are allowed on the S12XE family but not on the NE64. The MSL3 classification means reflow must complete within 168 hours after opening the drypack.
