MCU 16-bit HCS12 CISC 256KB Flash 80-Pin PQFP Tray, MC9S12A256CFUE, NXP

The MC9S12A256 MCU is a 16 bit device composed of standard on- chip peripherals, including a HCS12 CPU. System resource mapping, clock generation, interrupt control and bus interfacing are managed by the system integration module (SIM). The MC9S12A256 has full 16 bit data paths throughout, however the external bus can operate in an 8bit narrow mode so single 8bit wide memory can be interfaced for lower cost systems. The inclusion of a phase- lock loop (PLL) circuit allows power consumption and performance to be adjusted.

  • 16 bit HCS12 CPU
  • Upward compatible with M68HC11 instruction set
  • Interrupt stacking and programmer"s model identical to M68HC11
  • Instruction pipe
  • Enhanced indexed addressing
  • Multiplexed external bus
  • Memory
    • 256 KB flash EEPROM
    • 1 KB EEPROM
    • 4 KB RAM
  • Two asynchronous serial communications interfaces (SCI)
  • Three serial peripheral interfaces (SPI)
  • Two 8 channel ADCs
  • 8 channel pulse-width modulator (PWM)
  • 29 discrete digital I/O channels (Port A, Port B, Port K and Port E)
  • 20 discrete digital I/O lines with interrupt and wake-up capability
  • Inter-IC Bus
  • 10-bit resolution
  • Software-compatible modules
