PRODUCT BRIEF

MOTOROLA

General-Purpose I/O Support

• 24 Address pins and 32 data pins can be used for general-purpose I/O in single-chip mode

• 16 GPIO in MIOS14

• Many peripheral pins can be used as GPIO when not used as primary functions

• 2.6-V outputs on external bus pins

• 5-V outputs with slew rate control

NEXUS Debug Port (Class 3)

• Compliant with Class 3 of the IEEE-ISTO Nexus 5001-1999

• Program trace via branch trace messaging (BTM)

• Data trace via data write messaging (DWM) and data read messaging (DRM)

• Ownership trace via ownership trace messaging (OTM)

• Run-time access to on-chip memory map and MPC5xx special purpose registers (SPRs) via the

READI read/write access protocol

• Watchpoint messaging via the auxiliary port

• Reduced-port mode (1 MDI, 2 MDO) or full-port mode (2 MDI. 8 MDO)

• All features configurable and controllable via the auxiliary port

• Security features for production environment

• Supports the RCPU debug mode via the auxiliary port

• READI module can be reset independent of system reset

Integrated I/O System

Two Time Processor Units (TPU3)

• True 5-V I/O

• Two time processing units (TPU3) with16 channels each

• Each TPU3 is a micro-coded timer subsystem

• Eight-Kbytes of dual port TPU RAM (DPTRAM) shared by two TPU3 modules for TPU micro-code

22-Channel Modular I/O System (MIOS14)

• Six modulus counter sub-modules (MCSM)

• 10 double-action sub-modules (DASM)

• 12 dedicated PWM sub-modules (PWMSM)

• One MIOS14 16-bit parallel port I/O sub-modules (MPIOSM)

Two Enhanced Queued Analog-to-Digital Converter Modules (QADC64E)

• Two queued analog-to-digital converter modules (QADC64_A, QADC64_B) providing a total of 32

analog channels

• 16 analog input channels on each QADC64E module using internal multiplexing

• Directly supports up to four external multiplexers

• Up to 41 total input channels on the two QADC64E modules with external multiplexing

• Software configurable to operate in Enhanced or Legacy (MPC555 compatible) mode

• Unused analog channels can be used as digital input/output pins

— GPIO on all channels in Enhanced mode

• 10-bit A/D converter with internal sample/hold

• Typical conversion time of less than 5 µs (>200 K samples/second)

• Two conversion command queues of variable length

• Automated queue modes initiated by:

— External edge trigger

— Software command

— Periodic/interval timer within QADC64E module, that can be assigned to both queue 1 and 2

— External Gated trigger (queue 1only)

• 64 result registers

— Output data is right- or left-justified, signed or unsigned
