PSD3200 FAMILY
DRAFT(Thursday 20 June 2002, 13:15).
ARCHITECTURE OVERVIEW
Memory Organization
The
μ
PSD3200 Family’s standard 8032 Core has
separate 64KBaddress spacesfor Program mem-
ory, Data Memory.The Program memory consists
of two flash memory blocks: the main Flash (1 or 2
Mbit) and the Secondary Flash (256 Kbit). Except
during flash memory programming or update, Pro-
gram memory can only be read, not written to. A
Page Register is used to access memory beyond
the 64K bytes address space. Refer to the PSD
Module for details on mapping of the Flash mem-
ory.
The 8032 core has two types of data memory (in-
ternal and external) that can be read and written.
The internal SRAM consists of 256 bytes, and in-
cludes the stack area.
The SFR (Special Function Registers) occupies
the upper 128 bytes ofthe internal SRAM, thereg-
isters can be accessed by Direct addressing only.
There are two separate blocks of external SRAM
inside the
μ
PSD3200 Family:one 256 bytes block
is dedicated for DDC data storage. Another 8K
bytes resides in the PSD Module that can be
mapped to an address space defined by the user.

Registers
This device has several registers that are the Pro-
gram Counter (PC), Accumulator (A), B Register
(B), the Stack Pointer (SP), the Program Status
Word (PSW), General purpose register (R0to R7)
and DPTR (Datapointer register).
