4 Design Reference
As depicted in
an application developer. Details of the software modules are described in this section.
4.1
The 73S12xxF contains a high performance, embedded 80515 core, referred to as the ‘core’. It executes
all ASM51 instructions and has the same instruction set as the 80C51.
The core supports separate Program and Data memory as shown in
devices has two program sizes (32 KB and 64 KB). This program space is segmented into 512-byte
pages. There are 2048 bytes of external data RAM (XData or XRAM) and 256 bytes of internal data
RAM (IData or IRAM).
4.1.1 Program Memory
The 73S12xxF is available with either 64 KB or 32 KB of program memory. The 73S1209F/73S1210F
have 32 KB and the 73S1215F/73S1217F have 64 KB. Contact a Teridian Sales Representative for
ordering information.
