ADuC812

ARCHITECTURE, MAIN FEATURES
The ADuC812 is a highly integrated, true 12-bit data acquisi-
tion system. At its core, the ADuC812 incorporates a high
performance 8-bit (8052 compatible) MCU with on-chip
reprogrammable nonvolatile Flash program memory control-
ling a multichannel (eight input channels) 12-bit ADC.
The chip incorporates all secondary functions to fully support
the programmable data acquisition core. These secondary
functions include User Flash Memory, Watchdog Timer
(WDT), Power Supply Monitor (PSM), and various industry-
standard parallel and serial interfaces.

Figure 1. Program and Data Memory Maps
The lower 128 bytes of internal data memory are mapped as
shown in Figure 2. The lowest 32 bytes are grouped into four
banks of eight registers addressed as R0 through R7. The next
16 bytes (128 bits) above the register banks form a block of
bit addressable memory space at bit addresses 00H through 7FH.

MEMORY ORGANIZATION
As with all 8052 compatible devices, the ADuC812 has separate
address spaces for program and data memory as shown in Fig-
ure 1. Also as shown in Figure 1, an additional 640 bytes of
User Data Flash EEPROM are available to the user. The User
Data Flash Memory area is accessed indirectly via a group of
control registers mapped in the Special Function Register (SFR)
area in the Data Memory Space.
The SFR space is mapped in the upper 128 bytes of internal data
memory space. The SFR area is accessed by direct addressing
only and provides an interface between the CPU and all on-chip
peripherals. A block diagram showing the programming model
of the ADuC812 via the SFR area is shown in Figure 3.
