Specification

On-chip ROM

• 256 kbytes

On-chip RAM

• 8 kbytes

Bus state controller

(BSC)

• Address space: A maximum 64 Mbytes for each of two areas (CS0 and

CS1) (only in SH7149)

• 8-bit external bus (only in SH7149)

• 16-bit external bus (only in SH7149)

• The following features settable for each area independently

 Bus size (8 or 16 bits)

 Number of access wait cycles

 Idle wait cycle insertion

 Supports SRAM

• Outputs a chip select signal according to the target area

Data transfer

controller (DTC)

(only in F-ZTAT

version)

• Data transfer activated by an on-chip peripheral module interrupt can

be done independently of the CPU transfer.

• Transfer mode selectable for each interrupt source (transfer mode is

specified in memory)

• Multiple data transfer enabled for one activation source

• Various transfer modes

Normal mode, repeat mode, or block transfer mode can be selected.

• Data transfer size can be specified as byte, word, or longword

• The interrupt that activated the DTC can be issued to the CPU.

A CPU interrupt can be requested after one data transfer completion.

• A CPU interrupt can be requested after all specified data transfer

completion.

Interrupt controller

(INTC)

• Five external interrupt pins (NMI and IRQ3 to IRQ0)

• On-chip peripheral interrupts: Priority level set for each module

• Vector addresses: A vector address for each interrupt source

User debugging

interface (H-UDI)

(only in F-ZTAT

version)

• E10A emulator support

Advanced user

debugger (AUD)

(only in F-ZTAT

version supporting full

functions of E10A)

• E10A emulator support
