Product specification
Microcontrollers for monitors with DDC
interface, auto-sync detection and sync proc.
P83Cx80; P87C380

MEMORY ORGANIZATION
The Central Processing Unit (CPU) manipulates operands in two memory spaces. There are 512 bytes of internal data
memory, consisting of 256 bytes standard RAM and 256 bytes RAM buffer which is accessible as the Auxiliary RAM
(AUX-RAM) or addressed through DDCADR and RAMBUF. The memory map and address spaces are shown in Fig.3.
7.1
Program memory
The program memory consists of ROM: 8 kbytes (P83C880), 16 kbytes (P83C180), 24 kbytes (P83C280) and 32 kbytes
(P83C380). The program memory implemented in the P87C380 is a 16 kbytes EPROM (OTP).
7.2
Internal data memory
The internal data memory is divided into three physically separated parts: 256 bytes of RAM, 256 bytes of AUX-RAM,
and a 128 bytes Special Function Registers (SFRs) area. These can be addressed each in a different way as described
in Sections 7.2.1 to 7.2.3 and Table 3.

Internal data memory map
Notes
1. RAM locations 0 to 127 can be addressed directly and indirectly as in the 80C51.
2. RAM locations 128 to 255 can only be addressed indirectly.
