CPU Memory

To accommodate the memory requirements of the WAP browser, the telephone uses large memory Flash and SRAM with the
following configuration:
• 32 Mbits Flash memory organised as 2 M * 16
4 Mbits RAM organised as 256k * 16 plus 128k * 16 plus 128k * 16
• The 8 Mbits RAM consists of 2 Mbits HERCULES internal RAM, 2 Mbits external RAM only, and 2 Mbits external RAM on
MCP.
