Features & Applications

The MC9S12A256 microcontroller unit (MCU) is a 16-bit device composed of standard on-chip peripherals including a 16-bit central processing unit (HCS12 CPU), 256 Kbytes of Flash EEPROM, 12 Kbytes of RAM, 4 Kbytes of EEPROM.

The MC9S12A256 has full 16-bit data paths throughout. However, the external bus can operate in an 8-bit narrow mode so single 8-bit wide memory can be interfaced for lower cost systems. The inclusion of a PLL circuit allows power consumption and performance to be adjusted to suit operational requirements.

The MC9S12A256 microcontroller unit has two asynchronous serial communications interfaces (SCI), three serial peripheral interfaces (SPI), an 8-channel IC/OC enhanced capture timer, two 8-channel, 10-bit analog-to-digital converters (ADC), an 8-channel pulse-width modulator (PWM), a digital Byte Data Link Controller (BDLC), 29 discrete digital I/O channels (Port A, Port B, Port K and Port E), 20 discrete digital I/O lines with interrupt and wakeup capability, three CAN 2.0 A, B software compatible modules (MSCAN12), and an Inter-IC Bus.

Features:

  • Upward compatible with M68HC11 instruction set
  • Interrupt stacking and programmer's model identical to M68HC11
  • Instruction pipe
  • Enhanced indexed addressing
  • Multiplexed External Bus
  • Memory
  • 512 Kbyte Flash EEPROM
  • 4.0 Kbyte EEPROM
  • Two 8-channel Analog-to-Digital Converters
  • 10-bit resolution
  • Software compatible modules
