Table 5. Reset Timing Values
Wakeup Pins
The 8051 puts itself and the rest of the chip into a power down
mode by setting PCON.0 = 1. This stops the oscillator and PLL.
When WAKEUP is asserted by external logic, the oscillator
restarts, after the PLL stabilizes, and then the 8051 receives a
wakeup interrupt. This applies irrespective of whether the FX1 is
connected to the USB or not.
The FX1 exits the power down (USB suspend) state using one
of the following methods:
■
■
■
The second wakeup pin, WU2, can also be configured as a
general purpose I/O pin. This allows a simple external R-C
network to be used as a periodic wakeup source. Note that
WAKEUP is by default active LOW.

USB bus activity (if D+/D– lines are left floating, noise on these
lines may indicate activity to the FX1 and initiate a wakeup).
External logic asserts the WAKEUP pin.

Program/Data RAM
Size
The FX1 has 16 KBytes of internal program/data RAM, where
PSEN#/RD# signals are internally ORed to allow the 8051 to
access it as both program and data memory. No USB control
registers appear in this space.
Two memory maps are shown in the following diagrams:

Internal Code Memory, EA = 0
This mode implements the internal 16 KByte block of RAM
(starting at 0) as combined code and data memory. When the
external RAM or ROM is added, the external read and write
strobes are suppressed for memory spaces that exist inside the
chip. This allows the user to connect a 64 KByte memory without
requiring the address decodes to keep clear of internal memory
spaces.
Only the internal 16 KBytes and scratch pad 0.5 KBytes RAM
spaces have the following access:
