MC9S12A256MPVE

S12A 16-bit MCU, HCS12 core, 256KB Flash, QFP 112; • 16-bit HCS12 CPU\n• Upward compatible with M68HC11 instruction set\n• Interrupt stacking and programmer's model identical to M68HC11\n• Instruction pipe\n• Enhanced indexed addressing\n• Multiplexed external bus\n• Memory\n• 512 KB flash EEPROM\n• 4 KB EEPROM\n• 14 KB RAM\n• Two asynchronous serial communications interfaces (SCI)\n• Three serial peripheral interfaces (SPI)\n• Two 8-channel ADCs\n• 8-channel pulse-width modulator (PWM)\n• 29 discrete digital I/O channels (Port A, Port B, Port K and Port E)\n• 20 discrete digital I/O lines with interrupt and wake-up capability\n• Inter-IC Bus\n• 10-bit resolution\n• Software-compatible modules\n;

The MC9S12A512 MCU is a 16-bit device composed of standard on-chip peripherals, including a HCS12 CPU.\nSystem resource mapping, clock generation, interrupt control and bus interfacing are managed by the system integration module (SIM).\nThe MC9S12A512 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.\nThe inclusion of a phase-lock loop (PLL) circuit allows power consumption and performance to be adjusted.\n
