Communication

function

Ethernet controller

(ETHERC)

 2 channels

 Input and output of Ethernet/IEEE 802.3 frames

 Transfer at 10 or 100 Mbps

 Full- and half-duplex modes

 MII (Media Independent Interface) or RMII (Reduced Media Independent Interface) as

defined in IEEE 802.3u

 Detection of Magic PacketsTM*1 or output of a "wake-on-LAN" signal (WOL)

 Compliance with flow control as defined in IEEE 802.3x standards

 Filtering of multicast frames

 Direct transfer of frames between two channels by cut-through

PTP controller for

Ethernet controller

(PTP)

 A block compatible with the IEEE 1588 standard is connected to the Ethernet controller

(ETHERC).

 Matching with a time stamp can start counting by MTU3 and the GPT.

DMA controller for

Ethernet controller

(EDMAC)

 3 channels (the round-robin method determines the priority of the channels)

2 channels for ETHERC; 1 channel for EPTPC

 Alleviation of CPU load by the descriptor control method

 Transmission FIFO: 2 Kbytes; Reception FIFO: 4 Kbytes

USB 2.0 FS host/

function module (USBb)

 Includes a UDC (USB Device Controller) and transceiver for USB 2.0 FS

 One port

 Compliance with the USB 2.0 specification

 Transfer rate: Full speed (12 Mbps)

 Self-power mode and bus power are selectable

 OTG (On the Go) operation is possible

 Incorporates 2 Kbytes of RAM as a transfer buffer

 External pull-up and pull-down resistors are not required

USB 2.0 FS host/

function module with

battery charging

(USBA)

 Includes a UDC (USB Device Controller) and transceiver for USB 2.0 FS

 One port (only in 176-pin devices)

 Compliance with the USB 2.0 specification

 Transfer rate: full speed (12 Mbps), low speed (1.5 Mbps) (host only)

 Self-power mode and bus power are selectable

 OTG (On the Go) operation is possible

 Incorporates 8.5 Kbytes of RAM as a transfer buffer

 External pull-up and pull-down resistors are not required

Serial communications

interfaces (SCIg, SCIh)

 9 channels (SCIg: 8 channels + SCIh: 1 channel)

 SCIg

Serial communications modes: Asynchronous, clock synchronous, and smart-card

interface

Multi-processor function

On-chip baud rate generator allows selection of the desired bit rate

Choice of LSB-first or MSB-first transfer

Average transfer rate clock can be input from TMR timers for SCI5, SCI6, and SCI12

Start-bit detection: Level or edge detection is selectable.

Simple I2C

Simple SPI

9-bit transfer mode

Bit rate modulation

Double-speed mode

Event linking by the ELC (only on chanel 5)

 SCIh (The following functions are added to SCIg)

Supports the serial communications protocol, which contains the start frame and

information frame

Supports the LIN format

Serial communications

interface with FIFO

(SCIFA)

 4 channels

 Methods of transfer: Asynchronous and clock synchronous

 Desired bit rates can be selected from the internal baud rate generators.

 LSB or MSB first is selectable.

 Both the transmission and reception sections are equipped with 16-byte FIFO buffers,

allowing continuous transmission and reception.

 Bit rate modulation

 Double-speed mode
