Product Brief  
MC9S12B Family  
16-bit Microcontroller  
1 Introduction  
Designed for automotive multiplexing applications, members of the MC9S12B-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 MC9S12B-Family members are composed of  
standard on-chip peripherals including a 16-bit central processing unit (CPU12), up to 256K bytes of Flash  
EEPROM, 8K bytes of RAM, 2K bytes of EEPROM, two asynchronous serial communications interfaces  
(SCI), serial peripheral interface (SPI), an input capture/output compare timer (TIM), 16-channel, 10-bit  
analog-to-digital converter (ADC), an 8-channel pulse-width modulator (PWM), one CAN 2.0 A, B  
software compatible module (MSCAN12) and an Inter-IC Bus. System resource mapping, clock  
generation, interrupt control and bus interfacing are managed by the lite integration module (LIM). The  
MC9S12B-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.

PAD = 16 input only.  
22 inputs provide Interrupt capability (H =8, P= 8, J = 4, IRQ, XIRQ  
For 80 Pin Versions:  
Port A = 8, B = 8, E = 6 + 2 input only, J = 2, M = 6, P = 7, S = 4, T = 8, PAD = 8 input only.
