Renesas H8S/2268 Series Owner's manual

Regarding the change of names mentioned in the document, such as Hitachi
Electric and Hitachi XX, to RenesasTechnology Corp.
The semiconductor operations of Mitsubishi Electric and Hitachi were transferred to Renesas
Technology Corporation on April 1st 2003. These operations include microcomputer, logic, analog
and discrete devices, and memory chips other than DRAMs (flash memory, SRAMs etc.)
Accordingly, although Hitachi, Hitachi, Ltd., Hitachi Semiconductors, and other Hitachi brand
names are mentioned in the document, these names have in fact all been changed to Renesas
Technology Corp. Thank you for your understanding. Except for our corporate trademark, logo and
corporate statement, no changes whatsoever have been made to the contents of the document, and
these changes do not constitute any alteration to the contents of the document itself.

1.3 Operating Voltage and Frequency Specifications
Table 1.3 shows examples of the MCU operating voltage and frequency specifications supported
by the E6000. If the E6000 is used in an environment that exceeds the operating voltage range and
operating frequency range guaranteed for the MCU operation, normal emulator operation is not
guaranteed.

MCU Types Operating Voltage (V) Operating Frequency (φ) (MHz)
4.0-5.5 2-20.5
H8S/2268 series 2.7-4.0 2-13.5
NOTE
For details on the operating voltage and frequency
specifications, refer to the MCU hardware manual.

In the E6000, the clock can be selected by using the Configuration window or the Clock
command.
Table 1.4 Clock Selections
Clock Command
Parameter Configuration Window Setting Notes
Main clock Subclock Main clock Subclock
32 32 kHz internal clock10 t10MHz internal clock Target clock Default
32 32 kHz internal clock20 t20 MHz internal clock Target clock
t t Target Target clock
t2 t Target/2 Target clock
NOTE
The system clock (φ) frequency is the same clock
frequency input to the XTAL and EXTAL when external clock
t is specified. For example, when a 20-MHz crystal
oscillator is connected to the XTAL and EXTAL of the user
system, the system clock (φ) frequency is 20 MHz. When
external clock t2 is specified, the system clock (φ) frequency
is 1/2 of the clock frequency input to the XTAL and EXTAL.
The frequency of the E6000 internal clock specified with
the HDI CLOCK command is applied to the system clock (φ).

Section 2 User System Interface
All user system interface signals are directly connected to the MCU in the E6000 with no buffering
except for those listed below which are connected to the MCU through control circuits:
•NMI
•RESET
•MD2, MD1
•XTAL
•EXTAL
•OSC1
•OSC2
•STBY
2.1 Signal Protection
All user system interface signals are protected from over- or under-voltage by use of diode arrays
except for the AVcc and Vref.
The Vcc pins (except for the AVcc pin) at the head of the user system interface cable are
connected together. The E6000 monitors the voltage level of the Vcc pins and displays the power-
supply status in the Status Window.
2.2 User System Interface Circuits
The interface circuit between the MCU in the E6000 emulator and the user system has a signal
delay of about 8 ns due to the user system interface cable. And high-impedance signals will be
pulled up to the high level by pull-up resistors. When connecting the E6000 emulator to a user
system, adjust the user system hardware to compensate for propagation delays.
The following diagrams show the interface signal circuits
