8.24 Flash program memory
8.24.1
General description
The P89LPC920/921/922 Flash memory provides in-circuit electrical erasure and
programming. The Flash can be read, erased, or 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. In-System Programming and
standard parallel programming are both available. On-chip erase and write timing
generation contribute to a user-friendly programming interface. The
P89LPC920/921/922 Flash reliably stores memory contents even after 10,000 erase
and program cycles. The cell is designed to optimize the erase and programming
mechanisms. The P89LPC920/921/922 uses V
DD
as the supply voltage to perform
the Program/Erase algorithms.
8.24.2
Features
Parallel programming with industry-standard commercial programmers.
In-Circuit serial Programming (ICP) with industry-standard commercial
programmers.
IAP-Lite allows individual and multiple bytes of code memory to be used for data
storage and programmed under control of the end application.
Internal fixed boot ROM, containing low-level In-Application Programming (IAP)
routines that can be called from the end application (in addition to IAP-Lite).
Default serial loader providing In-System Programming (ISP) via the serial port,
located in upper end of user program memory.
Boot vector allows user-provided Flash loader code to reside anywhere in the
Flash memory space, providing flexibility to the user.
Programming and erase over the full operating voltage range.
Read/Programming/Erase using ISP/IAP/IAP-Lite.
Any flash program or erase operation in 2 ms.
Programmable security for the code in the Flash for each sector.
>100,000 typical erase/program cycles for each byte.
10 year minimum data retention.
8.24.3
ISP and IAP capabilities of the P89LPC920/921/922
Flash organization:
The P89LPC920/921/922 program memory consists of
two/four/eight 1 kB sectors. 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 to 64 bytes of a given page to be programmed at the
same time, substantially reducing overall programming time. An In-Application
Programming (IAP) interface is provided to allow the end user’s application to erase
and reprogram the user code memory. In addition, erasing and reprogramming of
user-programmable bytes including UCFG1, the Boot Status Bit and the Boot Vector
are supported. As shipped from the factory, the upper 512 bytes of user code space
contains a serial In-System Programming (ISP) routine allowing for the device to be
programmed in circuit through the serial port.
