E0C88F360
In the normal operation mode, set the terminals for the PROM programmer as below. The board must be de-
signed so that the terminal settings cannot be changed.
XSPRG:
Fix at a High level.
RXD, SCLK, CLKW: Open or fix at a High level.
TXD:
Open.
PROM serial programming mode
The PROM serial programming mode should be set when writing data to the PROM using a serial transfer from
the exclusive PROM writer (UNIVERSAL ROM WRITER II). This mode will be used for the programming of chip
products, because the programming can be done even when the IC has already been mounted on the board.
To create data to be written to the PROM, use the E0C88 assembler similar to the E0C88xxx.
The following explains the procedure of PROM serial programming.
<PROM serial programming procedure>
(1) Set the required terminals for serial programming as follows:
XSPRG: Set the terminal so that it will be fixed to a Low level. (A switch should be provided on the target
board to change the XSPRG terminal level between High and Low.)
Note:
The XSPRG terminal must be fixed at a Low level in the programming mode and at a High level in
the normal operation mode. Changing the voltage level may damage the IC.
RXD, TXD, SCLK: Connect to the PROM writer.
CLKW:
Connect to the PROM writer. A 3.072 MHz clock will be supplied from the PROM writer at program-
ming.
Other terminals should be set as below.
Input port (K) and I/O port (P) terminals: Fix at a High or Low level.
TEST terminal: Fix at a High level.
(2) Turn the IC (user target board) power (+5 V) on.
A power voltage must be supplied to the VDD and VSS terminals same as the regular operation so that the
OSC1 oscillation circuits operate normally.
(3) Turn the PROM writer on.
(4) Controls the RESET and XSPRG terminals as shown below.
RESET
XSPRG
PROM writer
power ON
1–2S
0.5–1S
Start of serial programming
mode
2–3S
(5) Start up us88f360.exe or jp88f360.exe in the personal computer, then load the 88f360.frm file. This allows
serial programming to begin.
After setting this mode, data can be written to the exclusive PROM writer (UNIVERSAL ROM WRITER II).
Refer to the "E0C88Pxxx Universal ROM Writer II User’s Manual" for the connection and operation of the
PROM writer.
PROM parallel programming mode
In the PROM parallel programming mode, the exclusive PROM writer (UNIVERSAL ROM WRITER II) transfers
data in parallel to the IC installed on the PROM writer to write data to it. The terminal setting is done by the PROM
writer. Thus there is no precaution on mode setting or board design.
Refer to the "E0C88Pxxx Universal ROM Writer II User’s Manual" for the operation of the PROM writer.
To create data to be written to the PROM, use the E0C88 assembler the same as the E0C88xxx.
