FAQ

What is the maximum operating frequency of the MC9S12NE64VTU core?

The MC9S12NE64VTU features an HCS12 CPU12 core with a maximum bus frequency of 25 MHz. This is achieved using the internal PLL (CRGV4) with a 1–25 MHz crystal or external clock source. The core executes instructions at 25 MHz, enabling real-time Ethernet frame processing and deterministic interrupt response critical for industrial control applications involving the MC9S12NE64VTU.

Does the MC9S12NE64VTU include an integrated Ethernet PHY?

Yes, the MC9S12NE64VTU integrates both the Ethernet Media Access Controller (EMACV1) and the Ethernet Physical Transceiver (EPHYV2) on-die. This eliminates the need for an external PHY IC and associated magnetics interface components, reducing BOM cost and PCB area. The EPHYV2 supports IEEE 802.3 10/100BASE-TX with autonegotiation and MII/RMII interface modes - a defining feature of the MC9S12NE64VTU.

What type of memory does the MC9S12NE64VTU provide, and how much?

The MC9S12NE64VTU includes 64 KB of on-chip Flash memory (S12FTS64KV3) and 8 KB of RAM. The Flash supports in-application programming (IAP), background debug, and security features including backdoor key access. The RAM is SRAM mapped into the HCS12 memory space and retains data during low-power Stop mode - essential for maintaining state in battery-backed applications using the MC9S12NE64VTU.

How many CAN controllers are integrated into the MC9S12NE64VTU?

The MC9S12NE64VTU integrates two independent CAN 2.0B controllers. Each supports full CAN protocol features including message buffering, hardware ID filtering, error handling, and bit-rate configuration up to 1 Mbps. These controllers operate concurrently and are accessible via dedicated CANH/CANL pins - making the MC9S12NE64VTU suitable for automotive gateways and industrial networks requiring dual-fieldbus redundancy.

What is the ADC resolution and channel count of the MC9S12NE64VTU?

The MC9S12NE64VTU features the ATD10B8CV3 analog-to-digital converter: a 10-bit successive-approximation ADC with 8 input channels (AN0–AN7). It achieves 12 µs conversion time and supports hardware triggering from timers or external pins. This ADC is fully integrated into the HCS12 memory map and supports scan sequences - a key capability for sensor monitoring tasks implemented on the MC9S12NE64VTU.
