General
Description
Features
Flash memory
organization
7663E–8051–10/08
The Flash memory increases EPROM and ROM functionality with in-circuit electrical erasure
and programming. It contains 128K bytes of program memory organized in 1024 pages of 128
bytes. This memory is both parallel and serial In-System Programmable (ISP). ISP allows
devices to alter their own program memory in the actual end product under software control. A
default serial loader (bootloader) program allows ISP of the Flash.
The programming does not require external high programming voltage. The necessary high pro-
gramming voltage is generated on-chip using the standard V

Flash internal program memory.
Boot vector allows user provided Flash loader code to reside anywhere in the Flash memory
space. This configuration provides flexibility to the user.
Default loader in Boot Flash allows programming via the serial port without the need of a
user provided loader.
Up to 64K byte external program memory if the internal program memory is disabled (EA =
0).
