Functional Description
Data Sheet
36
V2.1, 2008-08
This common memory space consists of 16 Mbytes organized as 256 segments of
64 Kbytes; each segment contains four data pages of 16 Kbytes. The entire memory
space can be accessed bytewise or wordwise. Portions of the on-chip DPRAM and the
register spaces (ESFR/SFR) additionally are directly bit addressable.
The internal data memory areas and the Special Function Register areas (SFR and
ESFR) are mapped into segment 0, the system segment.
The Program Management Unit (PMU) handles all code fetches and, therefore, controls
access to the program memories such as Flash memory and PSRAM.
The Data Management Unit (DMU) handles all data transfers and, therefore, controls
access to the DSRAM and the on-chip peripherals.
Both units (PMU and DMU) are connected to the high-speed system bus so that they can
exchange data. This is required if operands are read from program memory, code or
data is written to the PSRAM, code is fetched from external memory, or data is read from
or written to external resources. These include peripherals on the LXBus such as USIC
or MultiCAN. The system bus allows concurrent two-way communication for maximum
transfer performance.
32 Kbytes of on-chip Program SRAM (PSRAM) are provided to store user code or
data. The PSRAM is accessed via the PMU and is optimized for code fetches. A section
of the PSRAM with programmable size can be write-protected.
16 Kbytes of on-chip Data SRAM (DSRAM) are used for storage of general user data.
The DSRAM is accessed via a separate interface and is optimized for data access.
2 Kbytes of on-chip Dual-Port RAM (DPRAM) provide storage for user-defined
variables, for the system stack, and for general purpose register banks. A register bank
can consist of up to 16 word-wide (R0 to R15) and/or byte-wide (RL0, RH0, …, RL7,
RH7) General Purpose Registers (GPRs).
The upper 256 bytes of the DPRAM are directly bit addressable. When used by a GPR,
any location in the DPRAM is bit addressable.
1 Kbyte of on-chip Stand-By SRAM (SBRAM) provides storage for system-relevant
user data that must be preserved while the major part of the device is powered down.
The SBRAM is accessed via a specific interface and is powered in domain M.
