8.27 Flash program memory
8.27.1
General description
The P89LPC904 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 (256 bytes) or page (16 bytes). The
Chip Erase operation will erase the entire program memory. In-Circuit Programming
using standard commercial programmers is available. In addition, In-Application
Programming (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 P89LPC904 Flash reliably stores memory contents even
after more than 100,000 erase and program cycles. The cell is designed to optimize
the erase and programming mechanisms. The P89LPC904 uses V
DD
as the supply
voltage to perform the Program/Erase algorithms.
8.27.2
Features
Programming and erase over the full operating voltage range.
Byte-erase allowing code memory to be used for data storage.
Read/Programming/Erase using ICP.
Any flash program/erase operation in 2 ms.
Programming with industry-standard commercial programmers.
Programmable security for the code in the Flash for each sector.
More than 100,000 minimum erase/program cycles for each byte.
10-year minimum data retention.
8.27.3
Flash organization
The P89LPC904 program memory consists of four 256 byte sectors. Each sector can
be further divided into 16-byte pages. In addition to sector erase, page erase, and
byte erase, a 16-byte page register is included which allows from 1 to 16 bytes of a
given page to be programmed at the same time, substantially reducing overall
programming time. In addition, erasing and reprogramming of user-programmable
configuration bytes including UCFG1, the Boot Status Bit, and the Boot Vector is
supported.
8.27.4
Flash programming and erasing
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 In-Circuit Programming (ICP)
mechanism. This ICP system provides for programming through a serial clock- serial
data interface. Third, the Flash may be programmed or erased using a commercially
available EPROM programmer which supports this device. This device does not
provide for direct verification of code memory contents. Instead this device provides a
32-bit CRC result on either a sector or the entire 1 KB of user code space.
8.27.5
In-circuit programming (ICP)
In-Circuit Programming is performed without removing the microcontroller from the
system. The In-Circuit Programming facility consists of internal hardware resources
to facilitate remote programming of the P89LPC904 through a two-wire serial
