Fujitsu 

MB91191/192 Series

Bus Interface

• 16-bit address output, 8/16-bit data input and output

• Basic bus cycle : 2 clock cycles

• Supports interfaces for various types of memory

• Multiplexed data/address input/output

• Automatic wait cycles : Between 0 and 7 wait cycles can be specified independently for each memory area

• Unused data/address pins can be configured as input/output ports

• Supports little endian mode

Bit Search Module

• Searches, starting from the MSB, for the position of the first 1/0 bit transition in a word. The operation is

performed in one cycle.

Serial I/O

• 3 channels with internal buffer RAM (automatic transfer of up to 128 bytes)

• Independent send and receive buffer mode (automatic transfer of up to 64 bytes)

A/D Converter (Successive Approximation Type)

• 10-bit × 16 channels

• Uses successive approximation conversion method (conversion time : 8.4 µs @ 20 MHz)

• Channel scan function

• Hardware and software conversion start functions

• Internal FIFO (Software conversion : 6 stages, Hardware conversion : 6 stages)

Timers

• 16-bit × 4 channels

• 16-bit timer/counter × 1 channel (with square wave output)

• 8/16-bit timer/counter × 1 channel (with square wave output)

FG input unit

• Incorporates capstan, drum, and reel input circuits

Capture unit

• Internal 24-bit free-run counter (Minimum resolution = 50 ns @ 20 MHz)

• Internal FIFO (Data : 21-bit × 8, Detection : 8-bit × 8)

Programmable pattern generator

• Internal RAM buffer (PPG0 : 256 bytes, PPG1 : 64 bytes)

• Output timing resolution : 800 ns @ 20 MHz

• Includes an A/D converter hardware start function

Realtime timing generator

• RTG : 3 circuits

• Output timing resolution : 400 ns or 800 ns selectable

• Timing output ports : 5 ports

PWM

• 12-bit PWM × 6 channels (rate, multi-type)

• Base frequency = 78.1 kHz or 39.0 kHz (@ 20 MHz) selectable
