E0C88F360
s PROM PROGRAMMER AND OPERATING MODES
The biggest difference between the E0C88F360 and the E0C88xxx is that the E0C88F360 contains Flash
EEPROM as the ROM that allows the user to write data to it using the exclusive ROM writer (UNIVERSAL ROM
WRITER II). The E0C88F360 also has a built-in PROM programmer that controls writing data to the PROM.
The following explains the PROM programmer and the operating modes that are added for the programming
operation.
q Configuration of PROM Programmer
The configuration of the PROM programmer is shown below.

exclusive
PROM writer
The PROM programmer supports Serial Programming for writing data received in serial transfer and Parallel
Programming that uses a parallel transfer. The programming method will be described later.
Terminals
The PROM programmer uses the following input/output terminals. The following sections will explain handling the
terminals in each operating mode.
XSPRG: PROM serial programming mode setting terminal
RXD:
Serial data receive terminal
TXD:
Serial data transmit terminal
SCLK:
Serial clock input/output terminal
CLKW:
Serial programming source clock (3.072 MHz) input terminal
The parallel programming mode uses other terminals in addition to the terminals above. However, it is not neces-
sary to switch the lines on the board, because the IC is programed by directly installing it to the exclusive PROM
writer (UNIVERSAL ROM WRITER II).
q Operating Modes
Three operating modes are available in the E0C88F360: one is for normal operation and the others are for
programming.
1) Normal operation mode (Normal mode/High-speed mode)
2) PROM serial programming mode
3) PROM parallel programming mode
The operating mode is decided by the XSPRG terminal setting at power on or initial reset.
Normal operation mode
In this mode, the E0C88 core CPU and the peripheral circuits operate by the programmed PROM. The CPU can
enter this mode after the PROM programming has finished.
The PROM bit data is set to "1" at shipment. Therefore, the IC will not work even if the normal operation mode is
set before programming.
