Table 1-1. Function Specifications
Item Specification
Host interface RS-232C: D-SUB 25-pin, 9600, 19200, 38400, or 57600 bps
Printer interface
Note 1
: Half-pitch 36-pin conforming to IEEE 1284-1994
(Supports compatible mode and ECP mode.)
The interface can be selected with the I/F SELECT switch.
Target interface
Note 2
Connector: D-SUB 9-pin (receptacle)
Level conversion: Within target V
DD
input range (1.8 to 5.5 V)
Protection function: Overvoltage input protection circuit (guaranteed range: 15 V max.)
Supported interface: 3-wire, 3-wire + handshake (Max. SCK: 2.0 MHz)
Pseudo 3-wire (Max. SCK: 2.0 MHz)
UART (Max. bps: 76800 bps)
IIC (Max. SCK: 50 kHz)
Supply voltage
Note 3
Target V
PP
supply voltage: 2.7 to 10.3 V, max.: 200 mA
Target V
DD
supply voltage: 1.8 to 6.0 V, max.: 200 mA
Whether power is supplied from the PG-FP3 or from the user target can be selected
with the TARGET V
DD
switch.
An overcurrent protection circuit is provided for both V
PP
and V
DD
.
Supply voltage input Target V
DD
supply voltage input: 1.8 to 5.5 V, current consumption: 100 mA max.
CPU clock supply A 16-, 8-, 4-, or 2-MHz clock can be selected as the target CPU clock.
The on-board target clock can be also used depending on the application settings.
(PG-FP3-side interface: CMOS level output)
Master ROM A PROM (CMOS, 32-pin) to which the user program is written can be inserted in the
master ROM socket to allow the user program to be downloaded (max.: 500 kbytes).
Stand-alone Programming with only the PG-FP3.
Functions such as E.P.V., ERASE, PROGRAM, VERIFY, and LOAD can be selected and
executed with the MODE Key.
Notes 1. Only supported for Windows 95.
2. The maximum communication rate of the interface varies depending on the device used and the
environment.
3. V
DD
is supplied to the target system to supply power to the device to which a program is to be written.
The power is not enough to operate the target system of the user. Use the power supply on the target
for on-board program writing.
