MC9S12A128 : Microcontroller

The MC9S12A128 microcontroller unit (MCU) is a 16-bit device composed of standard

on-chip peripherals including a 16-bit central processing unit (HCS12 CPU), 128K bytes

of Flash EEPROM, 8K bytes of RAM, 2K bytes of EEPROM, two asynchronous serial

communications interfaces (SCI), two 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), 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 and an Inter-IC Bus. System resource mapping, clock generation, interrupt

control and bus interfacing are managed by the System Integration Module (SIM). The

MC9S12A128 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.
