The AM263Px family of devices utilize
an integrated On-Chip Static Random Access Memory (OCSRAM). Controllers for external
memory sources such as DDR are not included. The key functionality of the OCSRAM
module includes:
- Total of up to 3MB of RAM
- Can be used as code
and data memory by the R5FSS cores
- Can be used as data
buffers accessible by EDMA
- Four 64-bit wide independent
banks of size 512KB with 200Mhz operating frequency
- Accessible by all initiator
modules via the CORE_VBUSM interconnect as detailed in CORE_VBUSM
Interconnect.
- Protected with MPU firewalls
as detailed in System Memory Protection Unit (MPU)/Firewalls
- Loadable space for the
Secondary Bootloader (SBL) as detailed in Initialization Overview
- 64-bit ECC Support
- Read-Modify-Write
mechanism to support ECC update on memory writes less then 64-bits.
Read-Modify-Write operation works independently per bank and
requires one additional cycle to update.
