5.19 External Bus Interface (EBI)
5.19.1 Overview
5.19.2 Features
The NuMicro™ NUC100 Low Density LQFP-64 package equips an external bus interface (EBI) for
external device used.
To save the connections between external device and this chip, EBI support address bus and
data bus multiplex mode. And, address latch enable (ALE) signal supported differentiate the
address and data cycle.
External Bus Interface has the following functions:
External devices with max. 64K-byte size (8 bit data width)/128K-byte (16 bit data width)
supported
Variable external bus base clock (MCLK) supported
8 bit or 16 bit data width supported
Variable data access time (tACC), address latch enable time (tALE) and address hold
time (tAHD) supported
Address bus and data bus multiplex mode supported to save the address pins
Configurable idle cycle supported for different access condition: Write command finish
(W2X), Read-to-Read (R2R)
