6" Color Video Touch Panels
Specifications AXD-CV6 (Cont.)
Memory:
• 512 KB of SRAM and 2 MB of Flash for a total memory of 2.5 MB.
The following is a detailed explanation of the on-board memory parameters:
• Graphics Buffer Memory:
- SGRAM
- 1 Mbit x 32 ==> 4 MByte
- Non-user accessible
- Volatile
• Flash Memory:
- CMOS Flash
- 16 MBit x 8 ==> 2 MByte
- Partially user accessible
- Non-volatile
Note: ~400 kByte is used by the firmware and is accessible only to the
firmware during both normal operation and firmware downloads.
Note: ~1600 kByte is used by the user program and is used by TPD3
designs for bitmaps, icons, and fonts. This can be cleared using either the
external "ZAP!" command or the on-panel Factory Reset button.
• RAM:
- SRAM
- 256 kByte x 16 ==> 512 kByte
- Partially user accessible
- Non-volatile via the battery backup (
volatile when batteries are removed
)
Note: 256 kByte is used by firmware and is accessible only to the firmware
during normal operation.
Note: 256 kByte is used by the user program and is used by TPD3 designs
for buttons, pages, and everything else not listed in the above Flash param-
eter. This can be cleared using the external "ZAP!" command or
on-panel Factory Reset button.
• Component Video Buffer Memory:
- DRAM
- 256 kByte x 16 ==> 512 kByte
- Non-user accessible
- Volatile
• Clock Chip:
- RAM
- 31 Byte
- Non-user accessible
- Non-volatile via the battery backup (
volatile when batteries removed
)
- 31 bytes are used by the firmware to store AMX configuration information.
Note: If the battery is removed to clear the memory, it wipes out the AMX
configuration information.
• EPLD:
- EEPROM
- 32 Macrocells
- Non-user accessible
- Non-volatile
- Used by hardware for board logic (unable to clear or update)
