6 MPC565/MPC566 Product Brief MOTOROLA
Detailed Feature List
1.2.11.2 22-Channel Modular I/O System (MIOS14)
• 22-channel MIOS timer (MIOS14)
• Six modulus counter submodules (MCSM)
— Four additional MCSM submodules compared to MIOS1
• 10 double action submodules (DASM).
• 12 dedicated PWM submodules (PWMSM)
— Four additional PWM submodules compared to MIOS1 (shared with MIOS GPIO pins)
• MIOS real-time clock submodule (MRTCSM) provides low power clock/counter
— Requires external 32-KHz crystal
— Uses four pins: two for 32-KHz crystal, two for power/ground.
1.2.12 Two Enhanced Queued Analog-to-Digital Converter
Modules (QADC64E)
• Two enhanced queued analog to digital converters (QADC64E A, QADC64E B) with AMUXes
for 40 total analog channels.
• 10 bit A/D converter with internal sample/hold
— Typical conversion time is 4 µs (250-Kbyte samples/sec)
— Two conversion command queues of variable length
• Automated queue modes initiated by:
— External edge trigger/level gate
— Software command
— Periodic/interval timer, assignable to both queue 1 and 2
• 64 result registers in each QADC64E module
— Output data is right or left justified, signed or unsigned
• Synchronized clock mode allows both QADC64Es to see the same conversion clock. This allows
the two modules to look like one large QADC with four queues.
• Conversions alternate reference (ALTREF) pin. This pin can be connected to a different reference
voltage
1.2.13 Three CAN 2.0B Controller (TouCAN) Modules
• Three TouCAN modules (TouCAN_A, TouCAN_B, and TouCAN_C)
• 16 message buffers each, programmable I/O modes
• Maskable interrupts
• Programmable loopback for self-test operation
• Independent of the transmission medium (external transceiver is assumed)
• Open network architecture, multimaster concept
• High immunity to EMI
• Short latency time for high-priority messages
• Low power sleep mode, with programmable wake up on bus activity
• TouCAN_C pins shared with MIOS14 GPIO pins
