NS7520 modules
CPU module
The CPU uses an ARM7TDMI core processor. The ARM architecture is based on Reduced Instruction
Set Computer (RISC) principles, which result in high instruction throughput and impressive real-
time interrupt response for a small, cost-effective circuit. For more information about ARM7TDMI,
see the ARM7TDMI Data Sheet from ARM Ltd. (www.arm.com).
GEN module
The GEN module provides the NS7520 with its main system control functions, as well as these
features:
Two programmable timers with interrupt
One programmable bus-error timer
One programmable watchdog timer
Two 8-bit programmable general-purpose I/O ports
System (SYS) module
The system module provides the system clock (SYS_CLK) and system reset (SYS_RESET) resources.
The system control signals determine the basic operation of the chip:
Signal mnemonic
Signal name
Description
{XTALA1, XTALA2}
Clock source
Operate in one of two ways:
The signals are affixed with a 10-20 MHz parallel mode
quartz crystal or crystal oscillator and the appropriate
components per the component manufacturer.
XTALA1 is driven with a clock signal and XTALA2 is
left open.
{PLLVDD, PLLVSS}
PLL power
Provide an isolated power supply for the PLL.
RESET_
Chip reset
Active low signal asserted to initiate a hardware reset of the
chip.
{TDI, TDO, TNS,
TRST_, TCK}
JTAG interface
Provide a JTAG interface for the chip. This interface is used
for both boundary scan and ICE control of the internal
processor.
{PLLTEST_, BISTEN_,
SCANEN_}
Chip mode
Encoded to determine the chip mode.
