The P89LPC9401 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 bytes). The Chip Erase operation will erase
the entire program memory. ICP 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 P89LPC9401 flash reliably stores memory contents even after
100,000 erase and program cycles. The cell is designed to optimize the erase and
programming mechanisms. The P89LPC9401 uses V
the Program/Erase algorithms.
The program memory consists of eight 1 kB sectors on the P89LPC9401 device. Each
sector can be further divided into 64-byte pages. In addition to sector erase, page erase,
and byte erase, a 64-byte page register is included which allows from 1 byte to 64 bytes 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.
