signals
Description
1
Vpp
High voltage applied on the SPI Flash to speed up the
programming and erasing operations.
2, 3
CS1, CS2
Chip select of two Serial Flashes. Serial Flash 1 or 2 can be
selected from the software.
4
Vcc
Vcc is used to supply the application SPI Flash. The Vcc level
can be adjusted from the software. A diode protects the
SF600/SF600Plus Vcc from the application Vcc.
5
MISO/DQ1
Data out from the application memory (master in slave out)
when memory work in single IO mode. Bi-directional when
memory works in Dual or Quad IO mode.
6
Hold/DQ3
Driven High when Hold function is active. Bi-directional when
memory works in Quad IO mode.
7
Wp/DQ2
Driven High when Wp function is active. Bi-directional when
memory works in Quad IO mode.
8
CLK
SPI clock signal
9
GND
GND is the common ground shared between application and
programmer
10
MOSI/DQ0
Data in of the application SPI Flash (master out slave in)
when memory work in single IO mode. Bi-directional
when memory works in Dual or Quad IO mode.
12
Reset/IO3
Open drain output driven low prior any SF600/SF600Plus
operation. Reset/IO3 can be used to turn on the application
isolation circuit or reset the target system in order to drive the
Serial bus in High Impedance.
