NSC COP411L Single-chip n-channel microcontroller Datasheet

COP410L/COP411L/COP310L/COP311L
Single-Chip N-Channel Microcontrollers
General Description
Features
The COP410L and COP411L Single-Chip N-Channel Microcontrollers are members of the COPSTM family, fabricated
using N-channel, silicon gate MOS technology. These Controller Oriented Processors are complete microcomputers
containing all system timing, internal logic, ROM, RAM and
I/O necessary to implement dedicated control functions in a
variety of applications. Features include single supply operation, a variety of output configuration options, with an instruction set, internal architecture and I/O scheme designed to facilitate keyboard input, display output and BCD
data manipulation. The COP411L is identical to the
COP410L, but with 16 I/O lines instead of 19. They are an
appropriate choice for use in numerous human interface
control environments. Standard test procedures and reliable
high-density fabrication techniques provide the medium to
large volume customers with a customized Controller Oriented Processor at a low end-product cost.
The COP310L and COP311L are exact functional equivalents but extended temperature versions of COP410L and
COP411L respectively.
The COP401L should be used for exact emulation.

Functional Description
A block diagram of the COP410L is given in Figure 1 . Data
paths are illustrated in simplified form to depict how the various logic elements communicate with each other in implementing the instruction set of the device. Positive logic is
used. When a bit is set, it is a logic ‘‘1’’ (greater than 2V).
When a bit is reset, it is a logic ‘‘0’’ (less than 0.8V).
All functional references to the COP410L/COP411L also
apply to the COP310L/COP311L.
may also be loaded into the Q latches or loaded from the L
ports. RAM addressing may also be performed directly by
the XAD 3,15 instruction. The Bd register also serves as a
source register for 4-bit data sent directly to the D outputs.
The most significant bit of Bd is not used to select a RAM
digit. Hence each physical digit of RAM may be selected by
two different values of Bd as shown in Figure 4 below. The
skip condition for XIS and XDS instructions will be true if Bd
changes between 0 and 15, but NOT between 7 and 8 (see
Table III).
PROGRAM MEMORY
Program Memory consists of a 512-byte ROM. As can be
seen by an examination of the COP410L/411L instruction
set, these words may be program instructions, program data
or ROM addressing data. Because of the special characteristics associated with the JP, JSRP, JID and LQID instructions, ROM must often be thought of as being organized into
8 pages of 64 words each.
ROM addressing is accomplished by a 9-bit PC register. Its
binary value selects one of the 512 8-bit words contained in
ROM. A new address is loaded into the PC register during
each instruction cycle. Unless the instruction is a transfer of
control instruction, the PC register is loaded with the next
sequential 9-bit binary count value. Two levels of subroutine
nesting are implemented by the 9-bit subroutine save registers, SA and SB, providing a last-in, first-out (LIFO) hardware subroutine stack.
ROM instruction words are fetched, decoded and executed
by the Instruction Decode, Control and Skip Logic circuitry.
DATA MEMORY
Data memory consists of a 128-bit RAM, organized as 4
data registers of 8 4-bit digits. RAM addressing is implemented by a 6-bit B register whose upper 2 bits (Br) select 1
of 4 data registers and lower 3 bits of the 4-bit Bd select 1 of
8 4-bit digits in the selected data register. While the 4-bit
contents of the selected RAM digit (M) is usually loaded into
or from, or exchanged with, the A register (accumulator), it
*Can be directly addressed by
LBI instruction (see Table III)

Functional Description (Continued)
each low-going pulse (‘‘1’’ to ‘‘0’’) occurring on the SI
input. Each pulse must be at least two instruction cycles
wide. SK outputs the value of SKL. The SO output is
equal to the value of EN3. With EN0 reset, SIO is a serial
shift register shifting left each instruction cycle time. The
data present at SI goes into the least significant bit of
SIO. SO can be enabled to output the most significant bit
of SIO each cycle time. (See 4 below.) The SK output
becomes a logic-controlled clock.
2. EN1 is not used. It has no effect on COP410L/COP411L
operation.
3. With EN2 set, the L drivers are enabled to output the data
in Q to the L I/O ports. Resetting EN2 disables the L
drivers, placing the L I/O ports in a high-impedance input
state.
4. EN3, in conjunction with EN0, affects the SO output. With
EN0 set (binary counter option selected) SO will output
the value loaded into EN3. With EN0 reset (serial shift
register option selected), setting EN3 enables SO as the
output of the SIO shift register, outputting serial shifted
data each instruction time. Resetting EN3 with the serial
shift register option selected disables SO as the shift register output; data continues to be shifted through SIO and
can be exchanged with A via an XAS instruction but SO
remains reset to ‘‘0.’’ Table I provides a summary of the
modes associated with EN3 and EN0.
INTERNAL LOGIC
The 4-bit A register (accumulator) is the source and destination register for most I/O, arithmetic, logic and data memory
access operations. It can also be used to load the Bd portion of the B register, to load 4 bits of the 8-bit Q latch data,
to input 4 bits of the 8-bit L I/O port data and to perform
data exchanges with the SIO register.
A 4-bit adder performs the arithmetic and logic functions of
the COP410L/411L, storing its results in A. It also outputs a
carry bit to the 1-bit C register, most often employed to indicate arithmetic overflow. The C register, in conjunction with
the XAS instruction and the EN register, also serves to control the SK output. C can be outputted directly to SK or can
enable SK to be a sync clock each instruction cycle time.
(See XAS instruction and EN register description, below.)
The G register contents are outputs to 4 general-purpose
bidirectional I/O ports.
The Q register is an internal, latched, 8-bit register, used to
hold data loaded from M and A, as well as 8-bit data from
ROM. Its contents are output to the L I/O ports when the L
drivers are enabled under program control. (See LEI instruction.)
The 8 L drivers, when enabled, output the contents of
latched Q data to the L I/O ports. Also, the contents of L
may be read directly into A and M. L I/O ports can be directly connected to the segments of a multiplexed LED display
(using the LED Direct Drive output configuration option) with
Q data being outputted to the Sa–Sg and decimal point
segments of the display.
The SIO register functions as a 4-bit serial-in serial-out shift
register or as a binary counter depending on the contents of
the EN register. (See EN register description, below.) Its
contents can be exchanged with A, allowing it to input or
output a continuous serial data stream. SIO may also be
used to provide additional parallel I/O by connecting SO to
external serial-in/parallel-out shift registers.
The XAS instruction copies C into the SKL Latch. In the
counter mode, SK is the output of SKL in the shift register
mode, SK outputs SKL ANDed with internal instruction cycle
clock.
The EN register is an internal 4-bit register loaded under
program control by the LEI instruction. The state of each bit
of this register selects or deselects the particular feature
associated with each bit of the EN register (EN3 – EN0).
1. The least significant bit of the enable register, EN0, selects the SIO register as either a 4-bit shift register or a
4-bit binary counter. With EN0 set, SIO is an asynchronous binary counter, decrementing its value by one upon
INITIALIZATION
The Reset Logic will initialize (clear) the device upon powerup if the power supply rise time is less than 1 ms and greater than 1 ms. If the power supply rise time is greater than
1 ms, the user must provide an external RC network and
diode to the RESET pin as shown below (Figure 5) . The
RESET pin is configured as a Schmitt trigger input. If not
used it should be connected to VCC. Initialization will occur
whenever a logic ‘‘0’’ is applied to the RESET input, provided it stays low for at least three instruction cycle times.

Functional Description (Continued)
Upon initialization, the PC register is cleared to 0 (ROM address 0) and the A, B, C, D, EN, and G registers are cleared.
The SK output is enabled as a SYNC output, providing a
pulse each instruction cycle time. Data Memory (RAM) is
not cleared upon initialization. The first instruction at address 0 must be a CLRA.
CKO PIN OPTIONS
In a resonator controlled oscillator system, CKO is used as
an output to the resonator network. As an option, CKO can
be a RAM power supply pin (VR), allowing its connection to
a standby/backup power supply to maintain the integrity of
RAM data with minimum power drain when the main supply
is inoperative or shut down to conserve power. Using no
connection option is appropriate in applications where the
COP410L system timing configuration does not require use
of the CKO pin.
RAM KEEP-ALIVE OPTION
Selecting CKO as the RAM power supply (VR) allows the
user to shut off the chip power supply (VCC) and maintain
data in the RAM. To insure that RAM data integrity is maintained, the following conditions must be met:
1. RESET must go low before VCC goes below spec during
power-off; VCC must be within spec before RESET goes
high on power-up.
2. During normal operation, VR must be within the operating
range of the chip with (VCC b 1) s VR s VCC.
3. VR must be t 3.3V with VCC off.
I/O OPTIONS
COP410L/411L inputs and outputs have the following optional configurations, illustrated in Figure 7 :
TL/DD/6919 – 8
a. StandardÐan enhancement-mode device to ground in
conjunction with a depletion-mode device to VCC, compatible with LSTTL and CMOS input requirements. Available on SO, SK, and all D and G outputs.
b. Open-DrainÐan enhancement-mode device to ground
only, allowing external pull-up as required by the user’s
application. Available on SO, SK, and all D and G outputs.
c. Push-PullÐan enhancement-mode device to ground in
conjunction with a depletion-mode device paralleled by
an enhancement-mode device to VCC. This configuration
has been provided to allow for fast rise and fall times
when driving capacitive loads. Available on SO and SK
outputs only.
d. Standard LÐsame as a., but may be disabled. Available
on L outputs only.
e. Open Drain LÐsame as b., but may be disabled. Available on L outputs only.
f. LED Direct DriveÐan enhancement mode device to
ground and to VCC, meeting the typical current sourcing
requirements of the segments of an LED display. The
sourcing device is clamped to limit current flow. These
devices may be turned off under program control (see
Functional Description, EN Register), placing the outputs
in a high-impedance state to provide required LED segment blanking for a multiplexed display. Available on L
outputs only.

FIGURE 6. COP410L/411L Oscillator
OSCILLATOR
There are three basic clock oscillator configurations available as shown by Figure 6 .
a. Resonator Controlled Oscillator. CKI and CKO are
connected to an external ceramic resonator. The instruction cycle frequency equals the resonator frequency divided by 8. This is not available in the COP411L.
b. External Oscillator. CKI is an external clock input signal.
The external frequency is divided by 4 to give the instruction frequency time. CKO is now available to be used as
the RAM power supply (VR), or no connection.
Note: No CKO on COP411L.
Note: Series current limiting resistors must be used if LEDs are driven directly and higher operating voltage option is selected.
c. RC Controlled Oscillator. CKI is configured as a single
pin RC controlled Schmitt trigger oscillator. The instruction cycle equals the oscillation frequency divided by 4.
CKO is available as the RAM power supply (VR) or no
connection.
g. TRI-STATE Push-PullÐan enhancement-mode device
to ground and VCC. These outputs are TRI-STATE outputs, allowing for connection of these outputs to a data
bus shared by other bus drivers. Available on L outputs
only.
9
Functional Description (Continued)
h. An on-chip depletion load device to VCC.
i. A Hi-Z input which must be driven to a ‘‘1’’ or ‘‘0’’ by
external components.
The above input and output configurations share common
enhancement-mode and depletion-mode devices. Specifically, all configurations use one or more of six devices
(numbered 1 – 6, respectively). Minimum and maximum current (IOUT and VOUT) curves are given in Figure 8 for each
of these devices to allow the designer to effectively use
these I/O configurations in designing a COP410L/411L system.
The SO, SK outputs can be configured as shown in a., b., or
c. The D and G outputs can be configured as shown in a. or
b. Note that when inputting data to the G ports, the G outputs should be set to ‘‘1’’. The L outputs can be configured
as in d., e., f., or g.
a. Standard Output
An important point to remember if using configuration d. or
f. with the L drivers is that even when the L drivers are
disabled, the depletion load device will source a small
amount of current. (See Figure 8 , device 2.) However, when
the L port is used as input, the disabled depletion device
CANNOT be relied on to source sufficient current to pull an
input to a logic ‘‘1’’.
COP411L
If the COP410L is bonded as a 20-pin device, it becomes
the COP411L, illustrated in Figure 2, COP410L/411L Connection Diagrams. Note that the COP411L does not contain
D2, D3, G3, or CKO. Use of this option of course precludes
use of D2, D3, G3, and CKO options. All other options are
available for the COP411L.

L-Bus Considerations
In this program the internal Q register is enabled onto the L
lines and a steady bit pattern of logic highs is output on L0,
L1, L6, L7, and logic lows on L2 –L5 via the two-byte CAMQ
instruction. Timing constraints on the device are such that
the Q register may be temporarily loaded with the second
byte of the CAMQ opcode (XÊ 3C) prior to receiving the valid
data pattern. If this occurs, the opcode will ripple onto the L
lines and cause negative-going glitches on L0, L1, L6, L7,
and positive glitches on L2 –L5. Glitch durations are under
2 ms, although the exact value may vary due to data patterns, processing parameters, and L line loading. These
false states are peculiar only to the CAMQ instruction and
the L lines.
False states may be generated on L0 – L7 during the execution of the CAMQ instruction. The L-ports should not be
used as clocks for edge sensitive devices such as flip-flops,
counters, shift registers, etc. the following short program
that illustrates this situation.

Note 1: All subscripts for alphabetical symbols indicate bit numbers unless explicitly defined (e.g., Br and Bd are explicitly defined). Bits are numbered 0 to N where
0 signifies the least significant bit (low-order, right-most bit). For example, A3 indicates the most significant (left-most) bit of the 4-bit A register.
Note 2: For additional information on the operation of the XAS, JID, and LQID instructions, see below.
Note 3: The JP instruction allows a jump, while in subroutine pages 2 or 3, to any ROM location within the two-page boundary of pages 2 or 3. The JP instruction,
otherwise, permits a jump to a ROM location within the current 64-word page. JP may not jump to the last word of a page.
Note 4: A JSRP transfers program control to subroutine page 2 (0010 is loaded into the upper 4 bits of P). A JSRP may not be used when in pages 2 or 3. JSRP
may not jump to the last word in page 2.
Note 5: The machine code for the lower 4 bits of the LBI instruction equals the binary value of the ‘‘d’’ data minus 1 , e.g., to load the lower four bits of B (Bd) with
the value 9 (10012), the lower 4 bits of the LBI instruction equal 8 (10002). To load 0, the lower 4 bits of the LBI instruction should equal 15 (11112).
Note 6: Machine code for operand field y for LEI instruction should equal the binary value to be latched into EN, where a ‘‘1’’ or ‘‘0’’ in each bit of EN corresponds
with the selection or deselection of a particular function associated with each bit. (See Functional Description, EN Register.)

Description of Selected Instructions
Option List
The following information is provided to assist the user in
understanding the operation of several unique instructions
and to provide notes useful to programmers in writing
COP410L/411L programs.
The COP410L/411L mask-programmable options are assigned numbers which correspond with the COP410L pins.
The following is a list of COP410L options. The LED Direct
Drive option on the L Lines cannot be used if higher VCC
option is selected. When specifying a COP411L chip, Option
2 must be set to 3, Options 20, 21, and 22 to 0. The options
are programmed at the same time as the ROM pattern to
provide the user with the hardware flexibility to interface to
various I/O components using little or no external circuitry.
Option 1 e 0: Ground Pin Ð no options available
XAS INSTRUCTION
XAS (Exchange A with SIO) exchanges the 4-bit contents of
the accumulator with the 4-bit contents of the SIO register.
The contents of SIO will contain serial-in/serial-out shift register or binary counter data, depending on the value of the
EN register. An XAS instruction will also affect the SK output. (See Functional Description, EN Register, above.) If
SIO is selected as a shift register, an XAS instruction must
be performed once every 4 instruction cycles to effect a
continuous data stream.
Option 2: CKO Output (no option available for COP411L)
e 0: Clock output to ceramic resonator
e 1: Pin is RAM power supply (VR) input
e 3: No connection
Option 3: CKI Input
e 0: Oscillator input divided by 8 (500 kHz max)
e 1: Single-pin RC controlled oscillator divided by 4
e 2: External Schmitt trigger level clock divided by 4
Option 4: RESET Input

JID INSTRUCTION
JID (Jump Indirect) is an indirect addressing instruction,
transferring program control to a new ROM location pointed
to indirectly by A and M. It loads the lower 8 bits of the ROM
address register PC with the contents of ROM addressed by
the 9-bit word, PC8, A, M. PC8 is not affected by this instruction.
Note that JID requires 2 instruction cycles to execute.
LQID INSTRUCTION
LQID (Load Q Indirect) loads the 8-bit Q register with the
contents of ROM pointed to by the 9-bit word PC8, A, M.
LQID can be used for table lookup or code conversion such
as BCD to seven-segment. The LQID instruction ‘‘pushes’’
the stack (PC a 1 x SA x SB) and replaces the least
significant 8 bits of PC as follows: A x PC7:4, RAM(B)
x PC3:0, leaving PC8 unchanged. The ROM data pointed
to by the new address is fetched and loaded into the Q
latches. Next, the stack is ‘‘popped’’ (SB x SA x PC),
restoring the saved value of PC to continue sequential program execution. Since LQID pushes SA x SB, the previous contents of SB are lost. Also, when LQID pops the
stack, the previously pushed contents of SA are left in SB.
The net result is that the contents of SA are placed in SB
(SA x SB). Note that LQID takes two instruction cycle
times to execute.
INSTRUCTION SET NOTES
a. The first word of a COP410L/411L program (ROM address 0) must be a CLRA (Clear A) instruction.
b. Although skipped instructions are not executed, one instruction cycle time is devoted to skipping each byte of
the skipped instruction. Thus all program paths except
JID and LQID take the same number of cycle times
whether instructions are skipped or executed. JID and
LQID instructions take 2 cycles if executed and 1 cycle if
skipped.
c. The ROM is organized into 8 pages of 64 words each.
The Program Counter is a 9-bit binary counter, and will
count through page boundaries. If a JP, JSRP, JID or
LQID instruction is located in the last word of a page, the
instruction operates as if it were in the next page. For
example: a JP located in the last word of a page will jump
to a location in the next page. Also, a LQID or JID located
in the last word of page 3 or 7 will access data in the next
group of 4 pages.
