Discussion Groups | LPC900 | Abusing the LPC915 as slave for a 32-bit CPU
Find help, specifications and source code for the LPC900. The LPC900 challenges Microchip and AVR based on the worlds most popular 8-bit architecture the 80C51. With a 2-clock core the LPC900 series is a high performance, very flexible and low cost 8-bit microcontroller family. Designers using or interested in these devices are encouraged to share their know-how and ask questions.
Abusing the LPC915 as slave for a 32-bit CPU - lpc900 - Jul 12 18:49:00 2004
The LPC915 / LPC916 / LPC917 can be used as a companion chip for
higher performance CPUs. The functions performed range from external
EEPROM, power control device, low precision analog sensor, based on
multiple serial communication options.
The most interesting point is the minimal external requirements for
the LPC900 devices. The IRC is accurate enough to be used for serial
communications UART, SPI or I2C. With 2k Flash, there is enough memory
to combine a serial interface with a 1 KB EEPROM.
What do you think about such an abuse of the LPC microcontrollers?

An interesting approach to use a microcontroller instead of several
peripheral devices. I proposed the power control in the LPC2000 group
before but using a part of the micro es serial EEPROM sounds like good
use of existing resources.
Thanks for this hint.
