External Memory
Interface
Overview
Using the External
Memory Interface
26
ATmega162/V
With all the features the External Memory Interface provides, it is well suited to operate as an
interface to memory devices such as external SRAM and FLASH, and peripherals such as LCD-
display, A/D, and D/A. The main features are:
•
•
•
•
When the eXternal MEMory (XMEM) is enabled, address space outside the internal SRAM
becomes available using the dedicated external memory pins (see
on page
shown in
Figure 11. External Memory with Sector Select
Note:
The interface consists of:
•
•
•
•
•
Four Different Wait-state Settings (Including No Wait-state)
Independent Wait-state Setting for Different External Memory Sectors (Configurable Sector Size)
The Number of Bits Dedicated to Address High Byte is Selectable
Bus Keepers on Data Lines to Minimize Current Consumption (Optional)
AD7:0: Multiplexed low-order address bus and data bus
A15:8: High-order address bus (configurable number of bits)
ALE: Address latch enable
RD: Read strobe.
WR: Write strobe.
1. Address depends on the ATmega161 compatibility Fuse. See
