Product Proposal
HCS12DBFAMILYPP/D
Rev. 0.7, 8/2003
HCS12DB Family Product
Proposal
Freescale Semiconductor, Inc...
Introduction
Designed for automotive multiplexing applications, members of the
MC9S12DB-Family of 16 bit Flash-based microcontrollers are fully pin
compatible and enable users to choose between different memory and
peripheral options for scalable designs. All MC9S12DB-Family members are
composed of standard on-chip peripherals including a 16-bit central processing
unit (CPU12), up to 128K bytes of Flash EEPROM, 8K bytes of RAM, 2K bytes
of EEPROM, two asynchronous serial communications interfaces (SCI), up to
two serial peripheral interfaces (SPI), an enhanced capture timer (ECT), two 8-
channel, 10-bit analog-to-digital converters (ADC), an eight-channel pulse-
width modulator (PWM), Byteflight interface and up to two CAN 2.0 A, B
software compatible modules (MSCAN12). System resource mapping, clock
generation, interrupt control and bus interfacing are managed by the system
integration module (SIM). The MC9S12DB-Family 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. In addition to the I/O ports available
in each module, up to 22 I/O ports are available with Wake-Up capability from
STOP or WAIT mode.
