7.1 LPC1227 microcontroller
See the
LPC122x data sheet
for a detailed functional description of the LPC1227
microcontroller.

See the
PCF8576 data sheet
for a detailed functional description of the PCF8576D LCD
driver.
7.2.1
General description
The PCF8576D is a peripheral device which interfaces to almost any Liquid Crystal
Display (LCD) with low multiplex rates. It generates the drive signals for any static or
multiplexed LCD containing up to four backplanes and up to 40 segments. It can be easily
cascaded for larger LCD applications. The PCF8576D communicates via the two-line
bidirectional I
2
C-bus. Communication overheads are minimized by a display RAM with
auto-incremented addressing, by hardware subaddressing and by display memory
switching (static and duplex drive modes). Please refer to
PCF8576D data sheet
for
electrical data.
