Introduction
The MC9S12T64 microcontroller unit (MCU) is a 16-bit device
composed of standard on-chip peripherals including a 16-bit central
processing unit (HCS12 CPU), 64K bytes of Flash EEPROM, 2K bytes
of RAM, 2K bytes of CALRAM (Calibration RAM), two asynchronous
serial communications interfaces (SCI), one serial peripheral interface
(SPI), an 8 channel IC/OC enhanced capture timer, an 8-channel 10-bit
analog-to-digital converter (ADC), an 8-channel pulse-width modulator
(PWM), 25 discrete digital I/O channels (Port A, Port B, Port E and Port
K). System resource mapping, clock generation, interrupt control and
bus interfacing are managed by the System Integration Module (SIM).
The MC9S12T64 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.
