MPC5553/MPC5554 Microcontroller Reference Manual, Rev. 5
Freescale Semiconductor 1-9
— 16 kilobyte shared code memory in the MPC5554, 12 kilobyte shared code memory in the
MPC5553
— 3 kilobyte (MPC5554) or 2.5 kilobyte (MPC5553)Shared data memory
— Variable number of parameters allocatable per channel
— Double match/capture channels
— Angle clock hardware support
— Shared time or angle counter bus for all eTPU and eMIOS modules
— DMA and interrupt request support
— Nexus class 3 debug support (with some class 4 support)
• Enhanced queued analog/digital converter (eQADC)
— Two independent ADCs with 12-bit A/D resolution
— Common mode conversion range of 0–5 V
— 40 single-ended inputs channels, expandable to 65 channels with external multiplexers on 416
and 324 BGA packages
— 34 single-ended inputs channels, expandable to 57 channels with external multiplexers on
208 BGA packages
— Eight channels can be used as four pairs of differential analog input channels
— 10-bit accuracy at 400 ksamples/s, 8-bit accuracy at 800 ksamples/s
— Supports six FIFO queues with fixed priority.
— Queue modes with priority-based preemption; initiated by software command, internal (eTPU
and eMIOS), or external triggers
— DMA and interrupt request support
— Supports all functional modes from QADC (MPC5xx family)
• Four (MPC5554) or three (MPC5553) deserial serial peripheral interface modules (DSPI)
— SPI
– Full-duplex communication ports with interrupt and eDMA request support
– Supports all functional modes from QSPI submodule of QSMCM (MPC5xx family)
– Support for queues in RAM
– Six chip selects, expandable to 64 with external demultiplexers
– Programmable frame size, baud rate, clock delay, and clock phase on a per-frame basis
– Modified SPI mode for interfacing to peripherals with longer setup time requirements
— Deserial serial interface (DSI)
– Pin reduction by hardware serialization and deserialization of eTPU and eMIOS channels
– Chaining of DSI submodules
– Triggered transfer control and change in data transfer control (for reduced EMI)
• Two enhanced serial communication interface (eSCI) modules
— UART mode provides NRZ format and half or full-duplex interface
— eSCI bit rate up to 1 Mbps
