3.10 SDRAM Controller (SDRAMC)
can be used as data memory, program memory, or display memory.
(1) Supported SDRAM
(2) Supported initialization sequence commands
(3) Access mode
(4) Access cycles
(5) Auto generation of refresh cycles
The TMP92CF26A incorporates an SDRAM controller (SDRAMC) for accessing SDRAM that
The SDRAMC has the following features:
•
•
•
CAS latency (clock)
Note: The SDRAM address area is determined by the CS1 or CS2 setting of the memory controller. However, the

Auto Refresh is performed while the SDRAM is not being accessed.
The Auto Refresh interval is programmable.
The Self Refresh function is also supported.
