External Memory
Interface
Overview
Using the External Memory
Interface
2512K–AVR–01/10
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 Figure 1 on
page 2, Table 26 on page 66, Table 32 on page 70, and Table 38 on page 74). The
memory configuration is shown in Figure 11.
Figure 11. External Memory with Sector Select
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
