Random Access Memory
PS015313-0508
The eZ80F92 features 8 KB (8192 bytes) single-port data Random Access Memory
(RAM) for general-purpose use. The eZ80F93 features 4 KB (4096 bytes) general-pur-
pose RAM. RAM can be enabled or disabled, and it can be relocated to the top of any
64 KB page in memory. Data is passed to and from RAM via the 8-bit data bus. On-chip
RAM operates with zero WAIT states.
For the eZ80F92, RAM occupies memory addresses in the range {RAM_ADDR_U[7:0],

able 16 MB address space.
For the eZ80F93 device, RAM occupies memory addresses in the range
{RAM_ADDR_U[7:0],
RAM is enabled with RAM_ADDR_U set to
ory map of on-chip RAM. In this example, the RAM Address Upper Byte register,
RAM_ADDR_U, is set to
very small fraction of the available 16 MB address space.
