MCF51EM256 Series Configurations

front-plane/backplane pin assignments; operation in all low power modes with blink

functionality

— SCIx — Three serial communications interface modules with optional 13-bit break; option to

connect Rx input to PRACMP output on SCI1 and SCI2; high current drive on Tx on SCI1 and

SCI2; wakeup from stop3 on Rx edge. SCI1 and SCI2 Tx pins can be modulated with timer

outputs for use with IR interfaces

— SPIx— Two serial peripheral interfaces (SPI2, SPI3) with full-duplex or single-wire

bidirectional; double-buffered transmit and receive; master or slave mode; MSB-first or

LSB-first shifting

— SPI16— Serial peripheral interface (SPI1) with 32-bit FIFO buffer; 16-bit or 8-bit data

transfers; full-duplex or single-wire bidirectional; double-buffered transmit and receive; master

or slave mode; MSB-first or LSB-first shifting

— IIC — Up to 100 kbps with maximum bus loading; multi-master operation; programmable

slave address; interrupt driven byte-by-byte data transfer; supports broadcast mode and 10 bit

addressing

— MTIMx — Two 8-bit and one 16-bit modulo timers with 4-bit prescaler; overflow interrupt;

external clock input/pulse accumulator

— TPM — 2-channel Timer/PWM module; selectable input capture, output compare, or buffered

edge- or center-aligned PWM on each channel; external clock input/pulse accumulator; can be

used modulate SCI1 and SCI2 TX pins

• Input/output

— up to 16 rapid GPIO and 48 standard GPIOs, including 1 output-only pin and 3 open-drain pins.

— up to 16 keyboard interrupts with selectable polarity

— Hysteresis and configurable pullup device on all input pins; configurable slew rate and drive

strength on all output pins

• Package options

— 100-pin LQFP, 80-pin LQFP
