7.26 Flash program memory
The P89LPC9381 flash memory provides in-circuit electrical erasure and programming.
The flash can be erased, read, and written as bytes. The Sector and Page Erase functions
can erase any flash sector (1 kB) or page (64 B). The Chip Erase operation will erase the
entire program memory. In-Circuit Programming using standard commercial programmers
is available. In addition, IAP and byte-erase allows code memory to be used for
non-volatile data storage. On-chip erase and write timing generation contribute to a
user-friendly programming interface. The P89LPC9381 flash reliably stores memory
contents even after 100000 erase and program cycles. The cell is designed to optimize
the erase and programming mechanisms. The P89LPC9381 uses V
voltage to perform the Program/Erase algorithms.
The program memory consists of four 1 kB sectors on the P89LPC9381 devices. Each
sector can be further divided into 64 B pages. In addition to sector erase, page erase, and
byte erase, a 64 B page register is included which allows from 1 B to 64 B of a given page
to be programmed at the same time, substantially reducing overall programming time.
The flash code memory array of this device supports individual byte erasing and
programming. Any byte in the code memory array may be read using the MOVC
instruction, provided that the sector containing the byte has not been secured (a MOVC
instruction is not allowed to read code memory contents of a secured sector). Thus any
byte in a non-secured sector may be used for non-volatile data storage.
Four different methods of erasing or programming of the flash are available. The flash may
be programmed or erased in the end-user application (IAP) under control of the
application’s firmware. Another option is to use the ICP mechanism. This ICP system
