NXP's LPCHD00 and LPC12D00 integrate segment-LCD drivers

摘要

HThe Cortex-M0-based LPC11D00 and LPC12D00 microcontrollers integrate LCD drivers, enabling high contrast and brightness. Featuring the vendor's PCF8576D LCD driver, the units can drive any static or multiplexed LCDs containing as many as four backplanes and 40 segments. Designers can easily cascade these LCD drivers to accommodate as many as 2560 segments. The PCF8576D LCD driver supports a supply range of 2.5 to 6.5V, making the microcontrollers suitable for use in interfacing with both low- and high-threshold LCDs.
