APPENDIX A. HARDWARE INTERFACE EXAMPLES
Nand Flash devices can be connected to a micro-
controller system bus for code and data storage.
For microcontrollers that have an embedded
NAND controller the NAND Flash can be connect-
ed without the addition of glue logic (see
Figure 43.
). However a minimum of glue logic is
required for general purpose microcontrollers that
do not have an embedded NAND controller. The
glue logic usually consists of a flip-flop to hold the
Chip Enable, Address Latch Enable and Com-
mand Latch Enable signals stable during com-
mand and address latch operations, and some
logic gates to simplify the firmware or make the de-
sign more robust.
Figure 44.
gives an example of how to connect a
NAND Flash to a general purpose microcontroller.
The additional OR gates allow the microcontrol-
ler’s Output Enable and Write Enable signals to be
used for other peripherals. The OR gate between
A3 and CSn maps the flip-flop and NAND I/O in
different address spaces inside the same chip se-
lect unit, which improves the setup and hold times
and simplifies the firmware. The structure uses the
microcontroller DMA (Direct Memory Access) en-
gines to optimize the transfer between the NAND
Flash and the system RAM.
For any interface with glue logic, the extra delay
caused by the gates and flip-flop must be taken
into account. This delay must be added to the mi-
crocontroller’s AC characteristics and register set-
tings to get the NAND Flash setup and hold times.
For mass storage applications (hard disk emula-
tions or systems where a huge amount of storage
is required) NAND Flash memories can be con-
nected together to build storage modules (see
Fig-
ure 45.
).
