The MC9S12NE64 is a 112-/80-pin cost-effective, low-end connectivity applications MCU family. The MC9S12NE64 is composed of standard on-chip peripherals including a 16-bit central processing unit (HCS12 CPU), 64K bytes of FLASH EEPROM, 8K bytes of RAM, Ethernet media access controller (EMAC) with integrated 10/100 Mbps Ethernet physical transceiver (EPHY), two asynchronous serial communications interface modules (SCI), a serial peripheral interface (SPI), one inter-IC bus (IIC), a 4-channel/16-bit timer module (TIM), an 8-channel/10-bit analog-to-digital converter (ATD), up to 21 pins available as keypad wakeup inputs (KWU), and two additional external asynchronous interrupts.

The inclusion of a PLL circuit allows power consumption and performance to be adjusted to suit operational requirements. Furthermore, an on-chip bandgap-based voltage regulator (VREG_PHY) generates the internal digital supply voltage of 2.5 V (VDD) from a 3.15 V to 3.45 V external supply range. The MC9S12NE64 has full 16-bit data paths throughout. The 112-pin package version has a total of 70 I/O port pins and 10 input-only pins available. The 80-pin package version has a total of 38 I/O port pins and 10 input-only pins available.
