2.4 THEORY OF OPERATION
The 2070-1E LA City CPU consists of a single PCB assembly and a metal panel fixed by two screws and
two washers.
The assembly contains all of the control circuitry for the CPU functions: main processor, FLASH memory,
SRAM, PSRAM, RTC, a bidirectional buffer bank for the data, address lines and control lines coming from
the processor, a slave processor, the back-up capacitors, RESET circuit, isolation circuit for control
signals coming from the power supply, isolation circuit for SP8, C13S connector, C14S connector,
Ethernet circuit, DATAKEY circuit, driver filed circuit (RS 485 transceivers), LINESYNC circuit, A2 and A3
connector sensor, and A5 connector.
Main Processor
The 2070-1E LA City CPU uses the MC68360 Quad Integrated Communication Controller as the main
processor, it is clocked by and external 24.576MHz oscillator. The term "quad" comes from the fact that
there are four serial communications controllers (SCCs) on the device. However, there are actually seven
serial channels which include four SCCs, two serial management controllers (SMCs), and one serial
peripheral interface (SPI).
This processor handles the system buses, memory, serial communication ports (SP2, SP3, SP4, SP5 and
SP6), Ethernet communication and DATAKEY through SPI port; it also generates the CPU RESET and
FPA LED signals.
Slave Processor
This a MC68LC302 clocked by an external 16MHz oscillator. This processor handles the serial
communication ports SP1, SP8 and the baud rate for SP4.
Clocks

2070E LA City Controller –User Manual 11
Version 1.0
These different clock signals are used on the CPU.
24.576MHz oscillator is used for the main processor MC68EN360.
16MHz oscillator is used for the slave processor MC68LC302.
20MHz oscillator is used for the Ethernet interface transceiver.
25MHz oscillator is used for the Ethernet switch.
32.768KHz crystal is used for the RTC circuit.
Address Bus
This is a bidirectional 23-bit bus (A0-A22) capable of addressing up to 4GByte of data.
Data Bus
This is a bidirectional 32-bit bus (D0-D31) used to carry data among the processors, memories and other
system devices.
Decoding Signals
The signals for write enable, /OE, R/W’, CHIP SELECTS are used themselves and also are combined into
a glue logic stage in order to generate the required signals for the control and interaction among the
devices.
Buffer Circuit
This circuit consists of four octal bus transceivers SN74LVC245 and five octal bus transceivers
SN74LVC541 used to translate signals as data, address and some control lines from and to the other
board devices.
Transceivers SN74LVC245 connect the 32-lines data bus (D0-D31) from processor to other board
devices (memories, slave processor, RTC) and vice versa. The transceivers are enabled by the input /G
that is connected to the line D CSDB; when this line is HIGH the buses are effectively isolated, when
LOW the buses are enabled. The direction of the bus is controlled by the input DIR that is connected to
the line /DOE; when this line is LOW, communication is from bus B to bus A, when HIGH it is from bus A
to bus B.
Transceivers SN74LVC541 connect the 23-lines address bus from processor to other board devices
(memories, slave processor, RTC) and vice versa. The transceivers are enabled by the inputs /OE1 and
/OE2 that are tied to GND, then the buses are always enabled.
A5 connector
This 96-pin DIN connector is the physical interface between CPU and serial motherboard. It carries the
RS 485 differential signals for the communication ports S1 to SP6, the interruption signals LINESYNC,
POWERUP and POWERDN, the Ethernet transmission and reception lines, the +5VDC, +5VSTD and
+12VISO, A2 and A3 install lines, and the CPURESET and FPALED lines.

12
C13S Connector
This is a DB25 connector containing the RS 485 differential line communication signals for the SP8, the
external control signals from 2070 power supply also as RS 485 signals and the +5VDCISO power.
A2 and A3 Connector Sensor
This circuit is used to let know the CPU when the A2 and/or A3 slots on serial motherboard are being
used.
It is made of two inverter gates SN74LV04 (U18A and U18B) with pull-up and connected to the sensing
lines on A5 connector, these two lines come from the A2 and A3 slot connectors on serial motherboard.
The output of the inverter gates is LOW until A2 and/or A3 are used.
A2INSTALL: When A2 slot on serial motherboard is used, this line goes to GND forcing the output of
U18A to HIGH. This line enables the differential line drivers for SP1 and SP2 transmission.
A3INSTALL: When A3 slot on serial motherboard is used, this line goes to GND forcing the output of
U18B to HIGH. This line enables the differential line drivers for SP5 transmission.
Linesync Circuit
It is used to generate the /IRQ5 for processor, this interruption occurs on both rise and fall flanges of
LINESYNC signal.
It is implemented with two D-Type Flip-Flop SN74LV74, one inverter gate SN74LV04 and two buffer
gates 74LV125.
The two clear outputs are tied to +5VDC.
The two data input are tied to GND.
LINESYNC signal coming from 2070 power supply module is fed to CLK2, it is also inverted and fed to
CLK1.
The buffer gates’ inputs are tied to GND.
When LINESYNC transitions from LOW to HIGH at CLK2, Q2 goes to LOW and enables U19D
generating a LOW output.
When LINESYNC transitions from HIGH to LOW, inverter gate convert it to a LOW to HIGH transition at
CLK1, Q1 goes to LOW and enables U19C generating a LOW output.
The two active LOW preset inputs are connected to a pull-up and to the LINESYNC_CTL line; that is, the
outputs Q1 and Q2 of U6 are set to HIGH by using this line every time the processor receives the /IRQ5.
CPU Reset Circuit
This circuit receives the reset from main processor through the CPU LRESET line and sends the reset to
A5 connector through the CPURESET line; this reset is used by the other modules connected to serial
motherboard.
It is formed by using an inverter gate, two resistors, and one NPN transistor.
