P89LPC9331/9341/9351/9361
8-bit microcontroller with accelerated two-clock 80C51 core
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.
7.30.3 Flash organization
The program memory consists of sixteen 1 kB sectors on the P89LPC9361 devices and
eight 1 kB sectors on the P89LPC9341/9351 devices and four 1 kB sectors on the
P89LPC9331 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.
7.30.4 Using flash as data storage
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.
7.30.5 Flash programming and erasing
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
provides for programming through a serial clock/serial data interface. As shipped from the
factory, the upper 512 bytes of user code space contains a serial ISP routine allowing for
the device to be programmed in circuit through the serial port. The flash may also 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
user code space.
Remark: When voltage supply is lower than 2.4 V, the BOD FLASH is tripped and flash
erase/program is blocked.
7.30.6 ICP
ICP is performed without removing the microcontroller from the system. The ICP facility
consists of internal hardware resources to facilitate remote programming of the
P89LPC9331/9341/9351/9361 through a two-wire serial interface. The NXP ICP facility
has made in-circuit programming in an embedded application - using commercially
available programmers - possible with a minimum of additional expense in components
and circuit board area. The ICP function uses five pins. Only a small connector needs to
be available to interface your application to a commercial programmer in order to use this
feature. Additional details may be found in the P89LPC9331/9341/9351/9361 User
manual.
7.30.7 IAP
IAP is performed in the application under the control of the microcontroller’s firmware. The
IAP facility consists of internal hardware resources to facilitate programming and erasing.
The NXP IAP has made in-application programming in an embedded application possible
