TECHNICAL INF ORMATION CHAPTER 18
CPU
Z8S180, 18. 432 MHZ clock
ELECTRICAL
Memory
CAMBASIC, 32K ROM (U1). Mapped per below.
Programming and data is 128K RAM (U2). Expandable
to 512K by installing part number 1039.
Program s are stored in 128K Flash type EPRO M (U3).
Expandable to 512K by installing part number 1301.
Digital I/O
The RPC-2350 has 48 digital I/O lines from 82C55 IC.
24 are from J2, which is a general purpose port. The
other 24 are from J3. J3 has 8 high current outputs,
which may be jumpered for inputs. Keypad port J5 uses
8 of the 24 lines. LCD display port J6 uses another 8.
The specifications below are for all digital I/O except for
the eight high current lines at J3.
Drive current 2.5 mA. maximum per line,
sink or source. TTL
compatible.
Output low voltage 0.45V max at 2.5 mA, 1V
max at 15 mA. for opto rack.
Output high volts 2.4V minimum, sink or source
at rated current.
All digital input lines are TTL compatible.
High cu rrent ou tput at J3
8 of the 24 lines can drive up to 500 mA. at 50V. Refer
to CHAPTER 6, DIGITAL AND OPTO PORTS for
limitations.
Analog input(A/D)
Channels: 8
Ranges: 0-5V, ±2.5V
Resolution: 12 bits (4096 counts)
Accuracy: ±3 counts + 3 counts offset
Type: Single ended or pseudo differential
Conversion time: 500 m icro-seconds in CAMBASIC
Analog voltage output(D/A) (option)
Channels: 2
Ranges: 0-5V, ±5V, 0-10V
Resolution: 12 bits (4096 counts)
Accuracy: ±3 counts + 3 counts offset
Current output: 5 mA. for accuracy
Settling time: 2 micro-seconds
4-20 mA. output(option)
Channels: 2 (each requires its own D/A),
non-isolated
Input voltage: 12V to 30V or use on card supply
(.15V available)
Keypad input
10 lines accept a 16 to 24 position matrix keypad.
Scanning and debounce performed in CAMBASIC.
Uses 8 lines from J3. 24 position uses additional 2 lines
from J3.
Serial ports
Two RS-232D serial ports. COM1 has TxD and RXD
only. C OM2 also has RTS and C TS lines.
Programmable baud rates fr om 600 to 3 8.4 K, 7 or 8 data
bits, parity even, odd, or none, 1 or 2 stop bits.
Flash EPROM
Accepts Atmel 29C010A, 29C040A or equivalent
PEPROM.
Size:128K (29C010A) or 512K (29C040A)
Speed:120ns or faster.
Watchdog timer, reset
Watch dog timer resets card for 150 ms minimum when
enabled. Push button reset included.
Input power
+ 5VDC ±5% at 375 ma.
+ 12V at 250 mA. (RPC-2350G)
Current draw for 7-30V input depends upon applied
voltage. 7V supply draws more current (about 420 mA)
than 12V (about 200 ma).
Current consumption does not include any opto-modules
or other accessories.
Output power
+ 5V at P2: 750 mA. with 7 to 30V input at “7-30V”
terminal on P2, W8 jumpered.
±12V at J7 Up to 40 mA. @ + 12, 20 mA. @ -12V
Note: Subtract any curr ent used by analog
outputs.
