4 - MEMORY ORGANIZATION
ST10F269
14/184
4 - MEMORY ORGANIZATION
The memory space of the ST10F269 is configured
in a unified memory architecture. Code memory,
data
memory,
registers
and
I/O
ports
are
organized within the same linear address space of
16M Bytes. The entire memory space can be
accessed Byte wise or Word wise. Particular
portions of the on-chip memory have additionally
been made directly bit addressable.
Flash: 128K or 256K Bytes of on-chip Flash
memory.
IRAM:
2K
Bytes
of
on-chip
internal
RAM
(dual-port) is provided as a storage for data,
system stack, general purpose register banks and
code. A register bank is 16 Wordwide (R0 to R15)
and / or Bytewide (RL0, RH0, …, RL7, RH7)
general purpose registers.
XRAM: 10K Bytes of on-chip extension RAM
(single port XRAM) is provided as a storage for
data, user stack and code.
The XRAM is divided into 2 areas, the first 2K
Bytes named XRAM1 and the second 8K Bytes
named XRAM2, connected to the internal XBUS
and are accessed like an external memory in
16-bit demultiplexed bus-mode without wait state
or read/write delay (50ns access at 40MHz CPU
clock on PQFP144 devices and 62.5ns access at
32MHz CPU clock on TQFP144 devices). Byte
and Word accesses are allowed.
The
XRAM1
address
range
is
00’E000h
- 00’E7FFh if XPEN (bit 2 of SYSCON register),
and XRAM1EN (bit 2 of XPERCON register) are
set. If XRAM1EN or XPEN is cleared, then any
access in the address range 00’E000h - 00’E7FFh
will be directed to external memory interface,
using the BUSCONx register corresponding to
address matching ADDRSELx register
The
XRAM2
address
range
is
00’C000h
- 00’DFFFh if XPEN (bit 2 of SYSCON register),
and XRAM2 (bit 3 of XPERCON register are set).
If bit XRAM2EN or XPEN is cleared, then any
access
in
the
address
range
00’C000h
- 00’DFFFh will be directed to external memory
interface,
using
the
BUSCONx
register
corresponding to address matching ADDRSELx
register.
As the XRAM appears like external memory, it
cannot be used as system stack or as register
banks. The XRAM is not provided for single bit
storage and therefore is not bit addressable.
SFR/ESFR: 1024 Bytes (2 x 512 Bytes) of
address space is reserved for the special function
register areas. SFRs are Wordwide registers
which are used to control and to monitor the
function of the different on-chip units.
CAN1: Address range 00’EF00h - 00’EFFFh is
reserved for the CAN1 Module access. The CAN1
is enabled by setting XPEN bit 2 of the SYSCON
register and by setting CAN1EN bit 0 of the new
XPERCON register. Accesses to the CAN Module
use demultiplexed addresses and a 16-bit data
bus (Byte accesses are possible). Two wait states
give an access time of 100ns at 40MHz CPU clock
on PQFP144 devices (or 125ns at 32MHz CPU
clock on TQFP144 devices). No tri-state wait
states are used.
CAN2: Address range 00’EE00h - 00’EEFFh is
reserved for the CAN2 Module access. The CAN2
is enabled by setting XPEN bit 2 of the SYSCON
register and by setting CAN2EN bit 1 of the new
XPERCON register. Accesses to the CAN Module
use demultiplexed addresses and a 16-bit data
bus (Byte accesses are possible). Two wait states
give an access time of 100ns at 40MHz CPU clock
on PQFP144 devices (or 125ns at 32MHz CPU
clock on TQFP144 devices). No tri-state wait
states are used.
In order to meet the needs of designs where more
memory is required than is provided on chip, up to
16M Bytes of external RAM and/or ROM can be
connected to the microcontroller.
Note
If one or the two CAN modules are used, Port
4 cannot be programmed to output all 8
segment address lines. Thus, only 4 segment
address lines can be used, reducing the
external memory space to 5M Bytes (1M Byte
per CS line).
Visibility of XBUS Peripherals
In order to keep the ST10F269 compatible with
the ST10C167 and with the ST10F167, the XBUS
peripherals can be selected to be visible and / or
accessible on the external address / data bus.
CAN1EN and CAN2EN bits of XPERCON register
must be set. If these bits are cleared before the
global
enabling
with
XPEN-bit
in
SYSCON
register, the corresponding address space, port
pins and interrupts are not occupied by the
peripheral, thus the peripheral is not visible and
not available. Refer to Chapter : Special Function
